Question Will this motherboard limit my RAM speed?

[Shadow Slasher]

Hello guys! Today I bought a 64GB kit(2x32GB) RAM and a motherboard (Asus Rog Strix x570-e). However, the guy working at the shop told me that this motherboard might not support the full speed of my RAM, meaning it will not run at full speed on dual channel. Is he right about this? How can I check?

That RAM kit is 4x16gb and not 2x32gb. When using 4 sticks it can be harder to achieve higher RAM speeds.

If you are running Ryzen 3000 you will probably be able to run 3200Mhz in 4x16GB, but if it's Ryzen 2000 you will need to drop it down to 2933/3000Mhz.

I am running 2 sticks of 32GB each. My CPU is Ryzen 9 3950X. What do you think?

So you actually have 2x32GB for a total of 64GB and not a 4x16GB kit that you posted? Two modules have better chance of running at the rated specs than with four modules. So if it's actually 2x32GB, you should be fine to run it at 3200Mhz. The only way to know for sure is to try it and the worst that will happen is you will be stuck at 2666-3000Mhz.

Yes it was a mistake by me. I actually have 2x32GB sticks. So they'll run on dual channel at 3200MHz right?

This looks like the kit you meant to post https://www.corsair.com/us/en/Categ...EANCE-LPX/p/CMK64GX4M2C3200C16#tab-tech-specs. The tech specs state it's compatible with x570, so it will likely work at 3200Mhz. Just try it, that is the only way to know if it works. If it doesn't work, reduce the speed to 3000Mhz.
