Memory JEDEC or XMP

[Mercury98]

So, I'm running my PC without XMP. Because I want to test my computer this way first to see if everything is good. But I noticed that after a cold boot the input lag is different and I experienced a few other minor things (fast startup, fast boot disabled). It is possible that the motherboard always sets different timings or voltages after each cold boot, because after restarting the computer I do not experience this problem.

Cold post may train memory (voltages, not just timings) where a restart this process is not required.

Step one, fill out that PC information tab. It helps in trouble shooting.

Step two, read up on memory training. No clue if you have a DDR4/DDR5 (or a true "value" option DDR3)...so we can only point you in directions to educate yourself: Crucial article on memory training


Step three, now is the time to get your BIOS/UEFI updated. Yes, that's before you install an OS. Latest today will make updates later (barring critical security ones) less likely to be game changers. That said, every updated BIOS is likely to also require a full settings reset...so now is the time to get all your ducks in a row.



That's all the advice I can offer. Best of luck, and if you can bring more to the table it's more likely that you'll get a less generic answer.

Okay, I will update my specs as soon as I can. I think it's not my RAM, because I tested it with XMP and without XMP. Still changes input lag etc. Since I don't update it here is my
Pc specs:
-ASUS B660M Plus wifi d4
-I5-12400f
-DDR4 4000MHz Trident Z (from qvl list)
-Rtx 3070Ti
-750W Coolermaster MPE-7501-ACABW
-Kingston 1Tb ssd
-Windows 11 24H2
-Windows 10
-Dell G2723H
-Irid 503 argb V2: intel stock fan (cpu), 3 front and 1 back.

You probably can't get to 4000mhz memory (XMP) with that motherboard. The system Agent (memory controller) voltage is locked at 1.1v and requires more than that for high speed memory capabilities. You would need a Z series chipset to fully utilize the memory speed.

Try XMP enabled, but manually set 3600mhz and see if it posts.

I'm not sure I understand correctly. Theoretically, my motherboard can handle 4000MHz and can handle 1.4V. Also, before this, I had a RAM capable of maxing out at 3600MHz, which I only replaced because it wasn't on the qvl list at the suggestion of ASUS.

Because of the B series chipset, it is limited for overclocking, even the memory.

I do not overclock anything just the RAM.

Even the memory is limited.

Because System Agent voltage ️ is locked

Okay I understand it, but that mean should I to use it JEDEC? Or what is it mean? Because now my memory voltage is 1,4V, so it means it's higher than it should be? But this RAM is from the qvl list. So theoretically it shouldn't be a problem. Or does this belong to the cpu now? Because I know that the f series cannot be overclocked.

-ASUS B660M Plus wifi d4

This board is the issue. Ram on a support list does not mean it will actually work at this speed.

Yes, F processors can be overclocked, just not on that particular motherboard. You need a Z series motherboard for high frequency memory.


Try XMP enabled, but manually set 3600mhz and see if it works at that speed.

Oh, I ser now. I have had a 3600mhz RAM which also worked like that. Then I bought this one from qvl list (for b660m plus wifi d4). Should I try 3200MHz?
