How to use xmp with 4 sticks of DDR5?

Hi, i have recently upgraded to amds AM5 platform and with that i have got 4 new sticks of Corsair Vengeance RGB DDR5 16GB (6000mts).

However i am unable to run it at its rated speeds of 6000mts and instead am only able to reach 4800 with xmp off.

Does anyone know why this is and if i am able to get the rated speeds of 6000mt with 4 sticks

 

My build:

 

 

Motherboard: MSI MAG X670E TOMAHAWK WIFI

 

CPU : Ryzen 9 7900X

 

GPU: 3060ti xlr8 (i am upgrading soon dw)😅

 

RAM: Corsair Vengeance RGB DDR5 32GB (6000mts).

Running 4 sticks of DDR5 at 6000Mhz on AM5 is very difficult due to the memory controller.

You are defintely not the first person to ask this question here.

You would be better off sending the RAM back and getting 2 sticks instead.

You can try to update the BIOS to the latest version if you haven't already, this can improve memory compatability

6000Mhz across 4x DIMM's at Zen4's launch was near impossible unless you got lucky and really knew what you were doing. Today on the latest BIOSes it shouldn't be that bad, at least with Hynix kits. I don't know what that Corsair kit is using (half the reason I don't buy or suggest them) but setting XMP and manually lowering the clockspeed until its stable should be doable. 

 

Or are you saying you already did this and 4800 was as high as it would go?

4800mt was as high as i could set it with the 4 sticks

i had already tried updating bios to latest version and all my drivers are up to date too

Would i be better off using 2 sticks at the 6000mts with xmp or the 4 with no xmp at 4800?

It'll be practically impossible to reach 6000MHz unless you manually adjust the timings by hand. You could try your luck with 5200 or even 5600MHz, but 4x32gb is hard in any current platform. You probably could get a bit more lucky with 4x48gb sticks at 5600MHz, for some reason those are easier to manage.

Or just give up on using 4 sticks and go with 2 instead.

4x32gb is still nearly impossible to run at such frequencies.

Do you need 128gb of ram? In case you do, then having it be slower will be many times better than having to rely on swap.

Otherwise, just go with 64gb at 6000MHz.

i edited the topic sorry it is a 16gbx2 kit not 32gbx2

i only use this pc for heavy gaming loads and running Spotify ect at the same time

The graphics card i was going to get is a 4070ti super gigabyte gaming oc and im just worried that 32gb might not be enough for it or maybe im wrong?

32GB is plenty for heavy gaming 🙂

64GB is plenty overkill and 128 is just nuts.

Is there a reason you bought this and not 2x16GB? (which most of us have and its more than enough) 

 

Research prior to making purchases is important and would have prevented this problem. 

 

Can you achieve 6000 with just two DIMM's?

havent tried it with two dimms yet but i believe it will work and if speed is more preferable over "capacity" then i may settle with 32gb and sell the other two dimms

Yep. 32GB is plenty and speed over capacity at 32GB++ for gaming 🙂 Check the video above

Just to clarify/restate from some of the above comments: when you set manual speeds on DDR5, you're usually best off leaving XMP/EXPO enabled, because by enabling these you also get the board to configure itself for high speed memory and it will adjust more than just the RAM voltage. With DDR4 you could often get away with manual frequency and DRAM voltage, but DDR5 isn't like that.

 

If you turn XMP/EXPO off entirely, then you have to do DDR5's configuration manually and you'd need to read some memory overclocking guides to know which things to adjust on your motherboard.

 

The rated speed for 4 sticks (single or dual channel) for Zen 4 is just 3600, so AMD are really signalling there "...just don't", but you can definitely get 4x 16GB sticks a lot higher than 4800 if you push the right buttons.

Yeah, having more than 32gb is irrelevant in this case.

return the rams and buy a normal 2x32 kit done no more headaches with 4 stick not working cause garbage early gen imcs/boards

 

im just gonna assume that you play some really ram heavy games like modded minecraft or something like that

Absolutely. And owning this platform since the its release week, how easy this is has changed dramatically. 

 

I've done, no joke, 15 BIOS updates on my one motherboard since new. This isn't the same animal it was when it launched.
