 PC was get here with something new from asrock the B 450 M pro 4 motherboard along with the Athlon 200 G II processor why did I pick this processor you think with this board well I'm gonna tell you no give you good reasons for it first off this is an integrated APU with the GPU being the Vega 3 ok the Radeon Vega 3 this is running up 3.2 gigahertz this this processor ok and remember that so the CPU itself is 3.2 gigahertz with 5 mix of cash for of it is by the way 


level 3 cache which is pretty good for an entry level you know type of processor and 35 watts total very low energy low wattage and why would you get this for well for your home family PC right so you're doing some browsing video streaming photo editing email you're doing your presentations your homework office type of work you know stuff like that you want to hook up a couple monitors sure you can hook up up to 3 monitors in there will the support 4k video yes 

streaming 4k or watching 4k video yes it'll support that so pause the screen again any time that you want to look at this maximum temperature that this processor will support is 95 degrees Celsius so that's very high but it won't even get that high you know you can run this very cool and quiet now I'm not going to use the heatsink that it came with I'm gonna had liquid cooling on this one I'll tell you why now also other technologies that this will support nvme SSDs ok 

USB 3.1 gen2 4k video ddr4 and it uses the AM for socket so AMD has no plans on changing that for a while so you get yourself a cheap processor like this for anywhere from 50 to 60 dollars you pair it up with a board that has a sweet spot so a board that has the B 450 chip on it is the sweet spot for me because it's almost at the enthusiast higher-end level and it'll allow you to upgrade from the Athlon 200 GE later to a rise in processor for example right so save your 

money now wait for the prices that come down on the rise in processor then make the jump when you're ready for a risin and then you'll get the huge performance increase of that because the B 450 chipset will allow you to do that right not only that the B 450 allows you to get the store mi feature right which other chipsets other lower and boards will not have only so you only if you get the higher-end boards and the B 450 basically has that feature and I'll make a 

separate video about the store in life because it's quite interesting taking together your RAM your SSD and your regular hard drive putting it all together to really give you a boost and loading times is really a neat little trick now let's look at the asrock B 450 M pro 4 board ok features features features quality - we're looking for that right quality and construction something that's gonna last ok so first thing that kind of stands out to me is ok the ability for 

overclocking great ddr4 memory 3 200 megahertz and up if you're into that allowing you to have the crossfire X is a great feature if you're looking into that as well but I do like the 7.1 channel audio higher-end audio is really something that I look for I want the crisp low noise I want low leaks on those capacitors and want higher quality components in there and that's what it's got not just the fact that it has a super alloy board meaning that it has a layer of 2 ounce of copper in there for the conductivity and an efficiency of the energy delivery but also 

it's made with this fiberglass type of material on it as well and it's got digi power technology in there that they added in there basically to improve the CPU voltage efficiency on there right so later on down the line when you go to do your rise in overclocking you're gonna get some really nice results in the box you're gonna get the drivers your SATA cable your i/o plate manual and 2 screws should you decide to install an nvme m2 SSD so those SSDs that are basically a nice 

little thin slot that you can just slide it in there and then attach it with the one screw on to the board you can see one right there at the bottom of the board you can see that along with the fan headers and all those other clear CMOS and things like that so you got one down there and I'll show you the other one in a second USB ports along the bottom RGB header also along the bottom you've got your two PCI Express for your graphics cards as well and underneath that heat sink this asrock heatsink by the way that is keeping your B 450 chip cool okay in case 

you're wondering what that is the ultra MDOT 2 here is for another SSD so do you want to install another one in there and again it gives you that buffer that extra little space to future-proof yourself for different sized SSDs right so that's why we're calling it ultra now at the back of the board you've got all your input/output ports two USB regular ports with the ps/2 connector interesting to see that still VGA DVI HDMI you got it all there for your triple 

monitor setup and also your USB type a and type C Ethernet and your audio plug everything is there everything is there now at the back of the board right where the your DDR is you've got two fan headers two headers there if that's where your CPU cooler and that's why I'm going to be installing a CPU cooler in here to future-proof myself you know you can get it for about forty to fifty dollars right now for a new egg for a cooler master CPU cooler yes it's a little bit overkill for a processor such as the Athlon 200 GE but if I get that now I'm ready to go if I want

 to install a rising processor down the road no because of that this system is running super cool super cool and quiet okay I have it on defaults here is the ufi by us from asrock very nice clean design easy to read I like the color combo that they're using here the blue the gray is the blacks the white really easy to read and navigate the OC Tweaker section has all the options that you need to do some overclocking again the capabilities are there down the road your advanced 

settings allows you to turn on and off CPU and chipset features should you want to do that and of course you have under the tools section an RGB you know the the RGB header that I showed you earlier on the board you can control the colors for that one if you buy the appropriate components that make use of that right so again features are there you want to be able to control the fan you have the fan tuning option or you can manually set the fan modes yourself I 

like to set the fan mode sometimes they'll set them to silent mode because on a board like this with a chip like this you can do that right so why not why run things loud when you can run them nice and cool and quiet and that's pretty much it that's pretty much it like I said I'll be running more benchmarks but right now I'm gonna show you the temperatures right at full load so right now I've got this processor running a 3.2 gigahertz I forced it to run at a hundred 

percent full guns blazing full load 1.1 vaults is all it needed and basically running it out full load it barely breaks the sweat on those 2 cores 4 threads it's running about 40 degrees Celsius to be honest so again this is on the asrock B 450 M pro 4 board as you can see right there I didn't upgrade the bias this is right out of the factory right out of the box running it it's running stable I had no issues with it crashing I used memory that is running at 26 66 megahertz at CL 16 time and there you can see the Vega 3 graphics is basically idle because I'm only doing 2d right 

now I'm just recording my screen I'm not doing any 3d gaming yet so that's basically what it's doing it has one gig of memory right remember that's built in on the chip I didn't actually buy a separate graphics card it's built in on the same chip so that's the savings that you're getting when you buy this chip you can then future-proof yourself and down the road get a Rison processor and a graphics card and then you get a huge boost in performance but if you're not 

doing that for now and you just want it for your home use this is great this is this is gonna do the job if you're using it for school for studying for home office look at the temperatures here on the sensor that there it's saying that it's about 25 degrees 26 degrees there about 80 degrees Fahrenheit on the motherboard that's the motherboard temperature and then the CPU okay the actual processor is about 40 degrees Celsius or about a hundred degrees it's not even 

halfway of the full capabilities of the temperature so imagine you know how much hotter would be if I put a regular heat sink in there it'll be a little bit hot hotter but not that much still it's all relative I got the liquid cooling solution I've got a great board right and I've got a low-energy power saving type of processor so obviously you know the combination of all that means lower 

temperatures overall in the system now when we do some system benchmarks I'm gonna start off with CPU Z believe it or not now I'm running it on idle I took it off being a full load okay so it's running at idle there's the voltage it went down to 0.9 volts as you can see here and it has a benchmark tab here at the top and if I go into the benchmark tab at the top I ran here the single thread benchmark and the multi thread benchmark and it gave me two scores and it 

compared it to an AMD a10 7850 Cape processor right previous generation processor which also ran with two cords for two cores four threads and it beat it obviously and I would hope so because this is a newer newer chip I would expect it to be faster on all fronts but and when I wasn't fully convinced I took the score and went online and compared my scores on the single thread first to other processors scores and here it gives you a good sense on where this 

processor really fits compared to other generations right with other processors so you get a good feel for how this performs when it comes to single core type of benchmarks with the cpu-z benchmark now on the multi thread score which is 9 6 9 it changes right because there are different performance different tests it's multi-threaded for threads right and it compared it to these other types of processors so that's very interesting to see you know for those of you that 

are curious on where this really compares but I took at a level further we went to a 264 the CPU Queen and it does an overall benchmark on the processor working together of course with the asrock p450 empro right and it really you can tell that this board is bringing out maximum capabilities of this processor because it compared it to other four and eight core processors yes some of them are previous generations but still remember this is a two core entry level 

processor with the built-in graphics and it's comparing it to those other processors and and beating a lot of those so it's pretty pretty impressive now looking here at the performance test 9.0 again CPU score compared to other generation and other types of processors I was still impressed I'm impressed I mean of course it's not gonna beat eight core processors it better not but I mean for fifty to sixty US dollars you're getting a chip here that has a mix of features a 

mix of capabilities and again for your home office family regular use streaming video doing homework you know stuff like that it's good some very light gaming by the way so when it comes to 2d and 3d graphic benchmarks performance tests that well it's okay for 2d compared to these other graphics cards great for 2d okay but now if you try to push it and make some 3d graphics well obviously you know you can't expect much out of this for 3d graphics right so 

what does that mean can we still play games can we still do stuff with this when it comes to 3d well sure you can you just have to make sure that you run things on lower graphics settings so where this put it is about a three star rating maybe four and if you added a rise in processor in here it would have brought out the four star maybe even five star rating okay so keep that in mind now a PC mark and 3d mark work together there's different types of benchmarks nitrate is the new one that has tests on integrated graphics and again the temperature levels they're 

about 40 degrees Celsius and that's what I was looking for to see if we can push this to the max and comparing it to other office pcs that beat the score as well so I'm really happy to see that when we do some light gaming at 720p low graphic settings you can get about 30 plus frames per second which is you know what you want you want to at least 30 frames per second or higher for smooth visuals otherwise you know it's just not going to be good enough but again 

this is where it compares so there's some benchmarks that you can see from Final Fantasy and slide here from AMD that mentions a couple of other games running at 720p on different graphics settings so great combo here between these two future-proof yourself get the Athlon for now with the rising processor for later on this be 450m pro 4 board from asrock which is on sale now so not bad at all or that I'll add the link below if you're interested and comment let me know what you think .


the ass rock be 450m pro 4 this is a micro ATX board I picked this up to build another computer for another customer so before we do that we're gonna be taking a look at it doing some boxing maybe some memory a little bit of memory overclocking and some CPU overclocking with this thing and see how far we can push it alright so let's go ahead and get to the unboxing here ok so


 the first thing that greets us is memory configuration here this is just detailing how a strut recommends that you set up your memory you have your manual driver cities and you also get a Ches badge here this is just a sticker so those of you who are fans of this kind of stuff it's a pretty thick so nice little ass truck sticker there they've been to this kind of things yeah we're going to use the drivers on this city by the way we're gonna go to the website and get the latest 

drivers from that and then you get your back plate here just their ordinary all metal backplate you get your MDOT two screws here for screwing on your SSD into your MDOT to a slot don't lose those and you get your SATA cables one is at a 90 degree angle there okay okay so let's get to the motherboard here so let's split the box each side get all these accessories back in here 

alright guys so let's take a look here and here is the motherboard okay okay so let's take a good look at this thing here and I have to say that it's got a pretty nice-looking layout as far as aesthetically aesthetics go this doesn't have that matte black to the BCB that color but it does have a darker color it doesn't have that you know dark brown that other boards have seen have so it looks pretty nice and the heat sinks for the VRMs aren't actually a you know bit taller 

than I expected which is quite nice in my opinion I think that this should help with the BRM cooling there and not only do you get the RMS here on this side of the MOSFETs but you also get them up here where your SOC and you see the thermal pad there between the MOSFETs and the the heatsink that ass rock is using very nice you also get for ddr4 slots here dims for up to thirty two hundred megahertz we're gonna see if we can push beyond that but of course 

there's never any guarantees with that here you have your eight pin power connector here up at the top and your you've got a CPU fan header here and another chassis fan header and it looks like actually that's a that's an additional CPU fan header so you can you know you can use both of them as fan fan headers basically is what they're trying to say if you want to add like a pump or anything like that you also get another fan header here at the bottom you can see that there let's see what else do you have any other end you get two more fan headers sure the bottom 

PWM of course is very nice you don't have any debug LED lights with this board unfortunately but that shouldn't be a problem here you have your AMD fan LED or your for the LED lights on your MD cooler if you get like a rate cooler rate cooler that has the LEDs on it and now your 24-pin power cable there of course here also you have your USB 3.0 port for the front port your case from case connector there you have a four SATA six connectors here at a ninety degree 

angle you get one SATA in that two slot here you get your front panel connections here for your connector for your LED lights and hard drive activity lights all that stuff you get that down here oh yeah so you have to amped up two slots with this board which is really nice but this one here is a PCIe nvme slot so if you have a nvme card you want to put that here this will be your just regular SATA SATA 6 m dot 2 SSD if you're going with that here you have your two USB 

2.0 ports here at the bottom your comp connector you have your another RGB connector here which is really nice you have your audio out for your front panel and you have an isolated PCB as well on this on this board I'm not sure if this lights up it might we'll see when we turn it on and you have a high-quality caps as well for better audio quality and you also get a one PCI PCI e 4 x 4 here one slot here for your if you're using a like a PCIe type little SSD or you know

 a sound card or anything like that you have that there ok so see what else I want to forget to mention anything here but yeah pretty pretty neat layout here so let's go and move on to the back plate here or to the i/o ports yeah up at the top you see your two USB 2.0 ports you have your legacy ps/2 connector there you also get this is really nice going in old-school here you got your VGA connector there you have your HDMI connector yeah DB I'm sorry HDMI 

connector you also get a type-c connector there USB 3.1 port USB 4 USB 3.0 ports you have your Gigabit Ethernet port here and your audio out so yeah very nice looking very nice layout let's look at the back of the board here not that I'm expecting to see anything out of the ordinary but yeah you know just normal layout pretty simple one thing that I do pay attention though is again is these this soldering points here under PCI slots see that they're using some soldering there I mean I've seen that other boards they use a little bit more than this but this 

should be enough I mean it's is better than having the the old school like this retention brackets here instead of having this plastic stuff here and now they're using soldering which is really nice and see that's what I mean there that's what you don't want to see you see how that is I'm not using any solder there it's just the pin sticking out you don't want to see that here so that's very nice that they're doing that on your on your main slot there and you don't want these plastic 

stuff here either so yeah very nice one thing I didn't notice is that they're using plastic retention pins here for your for your vrn cooling for your heat sinks so these things can easily just move like this if you notice that I mean this is not an issue because it does have a thermal pad there so you don't do any damage but I prefer the screws in my opinion that's just you know I think it's more durable and a lot more reliable but yeah this shouldn't be an issue it should be a I made a 

major concern or anything like that but okay so aesthetically speaking the board looks really nice I think you guys would agree with that this is the ass Rock B 450m Pro floor this is the micro ATX option bypass rock for the AMD and for platform alright guys so let's go ahead and get this thing fired up or installed I should say and then we'll take a look at the BIOS , going into the BIOS were greeted by the typical ass rock layout they're simplistic very intuitive 

I love the ass rock BIOS us business actually one of my favorite boards for overclocking cioppino just to doing tweaking and things like that I have a lot of fun with this with this setup here basically here I was able to push my 2600 to 4.2 gigahertz stable 24/7 tested with prime95 for over two hours you know small FFTs as well as memory just that it would tested it with large FFTs for memory stability i did a little bit of tweaking on the sub timings as well using the rising calculators just to give me a little boost in performance there using the accent people 

profile and everything you know was flawless sparked right up as soon as i hit the power button so had no complaints with this board very stable very nice feature layout and also I didn't see much V group MIDI --scent v RM which I'm going to go a little more into here later in the video but I wonder to mention that up front so it is it is okay it is pretty decent it's better than a lot of the entry before 50 motherboards that I've seen out there so this is one one if you're 

gonna be looking for it before 15 motherboard make sure you put this one here on your list and as you can see I'm turned off all the things that you should turn off if you're gonna be doing overclocking like and be cool and quiet you know turn that off a global sea state turned it off you know you have another thing another good thing that I love here is how Astra has implemented fan control you know it's very simple very straightforward of you set to speed you know it gives you the the options are to choose whether if it's PWM DC mode or whatever and 

you go from there and you can see the changes live action as soon as you select the speed or whatever you want it actually you could hear the fans wind up so very nice bio setup so let's go ahead and take a look at some applications here I'm gonna go ahead and just do this kind of in a raw format I'm not going to edit so much of the stuff out because I want you guys to kind of you know see what it will be like and you know real life experience as you're going through the operating system here you know starting up and looking at your at your processor speed the 

voltage you know what that looks like your memory timings your you know your board BIOS all that stuff here my timings that I'm using what by tweaking the sub timings and the primary times with the rising calculator you can see here with all the changes that I made in case you've missed that in the BIOS and just to give it give you guys an idea what you can expect your you know with with this little board and doing a little bit of overclocking there on the memory or

 some out of 64 extreme just quick testing I'm sure I can get a little squeezed out a little more performance but I want to just kind of give you guys show these here this results are kind of you know live sort of speak but just so you guys get an idea what you're looking at there and also we're gonna go into prime95 not prime95 what am I saying Cinna pitch Cinebench r15 and do a quick run and keep it in mind that I have other stuff running in the background so that's you know the the score that you see here it's not a direct indicative of the actual performance I 

mean you can achieve a higher higher performance a higher score by doing a little bit of tweaking still and also shutting down some programs that are running in the background so yeah very stable I'm very happy with this board so I'm highly recommend it but now let's go ahead and talk a little bit about some extra features if you go to the ass Rock website so let's go ahead and get into that going to the ass Rock website and you can see a few more details on this 

board like AMD quad crossfire X if you want to go for that route if you want to set up like a quad crossfire setup on this board I wouldn't recommend such a thing because of the space and you know it's just the heating and all that stuff but that's your thing hey to each drone I was not able to go very much higher than thirty two hundred megahertz on this board for the RAM but I was able to improve the performance nevertheless ease in the rise in calculator and just you know dead a few sub timing tweaking there and that got me pretty good stable 

performance also they're using two ounce of copper PCB with this board here which is typical I mean ass rock they pride themselves with this kind of stuff also they're using a premium 42 amp power choke now this is the ISL 95 712 controller that they're using for the vrm on the on this board this is a three-phase a real three-phase to be our em but they're using double your service like you know three plus three you know six but it's a real three-phase plus I'm sorry by 

two so it's three by two two for the SOC so it's not the most powerful vrm you're gonna find out there but it is a before 50 board it is a you know sort of speaking kind of an entry board entry level or so for eighty dollars I mean you're getting good quality you got it you get into a strong quality here and you're getting pretty decent ventilation here with your VRM heatsinks you got you know those fins there to allow the air to flow ruling it you know keep you vrm 

temperatures down in case you want to do a little bit of tinkering with your mammary and you know bump up the clocks on your cpu that's really nice to have there also you get Elden audio quality here's two of them so that's another thing to look to look at but yeah overall like I said I'm very happy with the board I you know brought off the bat that have any issues with this 

just bark right up as soon as I press the power button so this thing is just up and rolling now and yeah I'm going to leave it here .
