3200MHz RAM speed, OC in B450 VS not OC in X570 AMD chipsets difference?

[Roy.Z]

Hi friends, 

 

I'm choosing parts for a new workstation build. I'm looking at motherboards and chipsets, The CPU will be Ryzen 3700x.

 

From what I see, RAM memory at the speed of 3200Mhz is listed with the B450 chipset motherboards as O.C only and the last speed which is not OC is 2133Mhz.

In X570 on the other hand its listed as not OC, and OC speeds starts at 3300Mhz while the last speed which is not OC is 3200Mhz. 

 

My question is, is there a difference? does it matter? in my country an X570 board costs double the price of a B450 board so the price does matter, but how about performance? 

 

I am looking at Corsair 3200Mhz CL16 2x16gb memory for the new build.

 

Thanks for your help!

 

Roy.

x470 /b450 Had some memory issues beyond 3000 mhz in certain boards. I would highly suggest getting a Quality kit in your area, Look if you can find a Samsung B-die or Micron Die type RAM. Avoid Hynix ram as its hit or miss a lot and not consistent (ive tried a few different ones on my x570 Aorus master and they are wonky) so keep an eye out. 16 GB shouldnt cost much at all.

If you're only running 3200MHz memory, then it makes no difference. older boards are rated for lower only because they were tested with older Ryzen carrying their worse memory controllers.

Thank you, I'll sure will take your advice and make sure it's not Hynix.

Thanks, are you sure about that? Both Motherboards list their support for 3rd generation Ryzen CPU's so why wont they update the RAM clocks on the B450 boards?

 

One of the boards I'm looking at is the ASUS TUF-B450-PLUS-GAMING and this is what it says in the specs:

 

Quote

4 x DIMM, Max. 128GB, DDR4 4400(O.C)/3466(O.C.)/3200(O.C.)/3000(O.C.)/2800(O.C.)/2666/2400/2133 MHz Un-buffered Memory
Dual Channel Memory Architecture

I want to know if it's perfectly fine or I should be looking at an x570 board like the ASUS PRIME X570-P which says this in the specs:

4 x DIMM, Max. 128GB, DDR4  4400(O.C)/4266(O.C.)/4133(O.C.)/4000(O.C.)/3866(O.C.)/3733(O.C.)/3600(O.C.)/3466(O.C.)/3400(O.C.)/3200/3000/2933/2800/2666/2400/2133 MHz Un-buffered Memory

 

I'm also looking at the GigabyteB450-AORUS-M which lists this: 

 

Quote

Support for DDR4 3600(O.C.) / 3466(O.C.) / 3200(O.C.) / 2933/2667/2400/2133 MHz memory modules

 

How come the two different B450 have different RAM specs? isn't it suppose to be the same and what's supported with the CPU? 

 

I'm so tired digging into specs lol.. Thanks a lot!

The asu tuf b450 is decent. If you do not need gen 4 m.2ssds or gpus then you do not need x570. Yes you can upgrade better in future and it has better vrm. If you want to upgrade in the future without byuing new mobo the x570 asus prime-P will be good enough.

You do not need 32gigs of ram. Save that money for future or better x570 (asus prime pro).

Get 2x8 gb 3600mhz cl16 instead (for x570, g.skill rippjaws 3600mhz cl16 is decent). For b450 some 3200mhz cl16 kit is enough

Had to do with the quality of the chip as it's binned by the manufacturer

.

The same binning process used for a CPU is also done with a chipset and if the particular chip doesn't measure up to X570 standards for example, it gets named as a B450 and it's specs are set that way to guarantee it will perform as stated. If it's a really underperforming chip when tested it gets called and spec'ed as something of an even lesser chipset model, it all depends on how good the chip is once it's made and checked.

.

All chips when the manufacturing process is done has to go through the binning process and the goal is to get as many good chips (X570's) as possible but rather than toss all that fails to meet the specs of an X570 they just use them as lesser chipsets by name.

 

The other factor is in how the manufacturer of a board themselves classify and spec them, some tend to be more generous than others with the specs but they don't always measure up according to the tweaking options it has.

Some make it, some don't.

Thank you, that's interesting to know.. 

 

So after all that, should I trust the B450 chipset with a 3200MHz memory? or I should opt for an X570 board?

 

Thank you all!

There is a marked difference between the 2xxx and 3xxx chips in terms of RAM speed achieved.

The CPU makes the biggest difference here, not so much the board but it's a factor too. The 3700X should be capable of 3200 with either board but for options, tweaking and so on the X570 board is the better choice to use.

 

Also, since you're talking about a workstation the X570 would have more useful features too such as extra USB ports and so on. I'd check things over for features between board makes and models and whatever has what you need, go with it because once you buy the board it's yours.

 

Just doesn't make sense to pay for something that comes up short on what you really may need or want.

Buy it once, buy it right.

Thank you, I really don't need anything the x570 offers in terms of connectivity, and it costs $240 in my country when the B450 boards cost $120.. so I just wanted to be sure the 3200MHz will work with the B450 and I wont have an issue with it.. 

 

Thanks again.

because changing rated specs after you start selling a product is the best way to attract lawsuits. You cant guarantee products already shipped out to be equally good as those you're making now (even if they are the same model) as those werent tested the same way today and could pass past QC but fail today's.

Zen 2 (3rd gen) CPUs support 3200MHz without overclocking, Zen+ (2nd gen) only goes up to 2933. You could go higher, but that's considered an overclock and no guarantees from AMD to do that.

 

the 4400MHz spec on the Asus B450 TUF Plus board is done with Zen 2 CPU, since Asus decides that the marketing benefits outweigh the costs of validation and risk of old boards getting RMA (even though they can still fault it for a ton of reasons, "your CPU isnt good enough" or "you didnt use the same memory kit as we do")

This can't be more wrong, B450 is designed by Asmedia while X570 is designed by AMD (literally, the I/O die inside a Zen 2 CPU). You cant bin a bad X570 chipset into a B450 when they arent even the same thing

Hmmm.... I'll have to check on that.
Not doubting you since I had always thought most if not all of the AM4 chipsets were made by the same company.

They are all made by GlobalFoundaries, you're not wrong on this one

Thank you all, so @Jurrunio, So does that might mean that the X570 will give somewhat better quality being made by AMD for an AMD CPU?

no, since all chipsets are made to fit specs set by AMD
