DDR5 RAM - DRAM Status 4800Mhz? Corsair Dominator 2x16GB 6000MT/s C30 + ASUS X670E-Plus WIFI.

01001101 · 30 Dec 2022 at 11:56

Hello..

I was wondering if anyone here is able to help? I'm a bit lost with the following..

I don't understand why my system is telling me that my DRAM status is 4800Mhz when in the bios is says it's set to 6000Mhz?

Thank you in advance!

Could be a glitch

Download cpuz and check memory to confirm your at 6000mhz and same timmings as xmp.

Remember it's double date ram so it will show 3000 and then doubled .

@01001101 If you click on memory not SPD it should show frequency and timings the memory is running at.

That looks correct its running at 6000mhz I'm guessing the 4800mhz you see is just default frequency.

01001101 · 30 Dec 2022 at 12:46

@mickyflinn So.. No worries then? Everything looks good?

the memory in the bios will always show its default speed and timmings, speed is always 4800mhz but timmings differ between kits, as long as you enable expo your ram will run at its rated max speed and not 4800hmz, its the same on my asus board, until i boot my system shows ram at 4800mhz, think of it as a fail safe if expo goes wrong the board will default back during memory traning (code15) and allow you to boot instead of not and boot looping.

all's sorted above so dont worry
