DDR5 Memory won't go past 4000mhz to reach 4800mhz on Z690-F

[birdjungle]

Page 8 of your motherboard memory QVL shows all three 8GB, 16GB, and 32GB Dell 4800 modules, they are listed as Venders: SK Hynix.

Attachment 92331

Attachment 92332

Attachment 92333

This is what I see when I go to my boards memory compatibility list.

Try this Memory QVL Support Link for your board : https://rog.asus.com/us/motherboards...esk_qvl_memory

Looks like the link your on is wacked, thare should be like 10-pages of memory in your QVL.

I think the disconnect is that I chose 2x32GB under size. But if I unselect that I see 4 pages worth

Hi guys, i have a question. i have a z690-a prime and 2 8gb crucial rams at 4800. if i put the sticks at recommended slots(A2 B2) every thing is fine and i can run them at full speed (4800mh) but if i put those 2 sticks in A1 B1 slots the speed is limited to 4000mhz. Is this how these new motherboards build?

This worked for me:

ddr5 dimm XMP fix (especially for 4 dims):
VDD = 1.300
VDDQ = 1.300
PMIC voltages = By Per PMIC

Note: Your CPU overclock also may play apart in stability as it did me, I did not win the CPU lottery (SP= 88) so I overclocked manually all core 5ghz, 51x4,52x2 core, vcore 1.328 with 0.100 negative offset combined with the above for my corsair dominators CL40 (2x32). = stable and temps are bellow 87 under load and cinebench (realtime) score = 28140

Hope this helps someone.

Stick to the slots as allocated in the manual to utilise the correct number of channels/speed. There are reasons at an electrical level why these are the preferred slots.

Hi guys, i have a question. i have a z690-a prime and 2 8gb crucial rams at 4800. I put the sticks at recommended slots(A2 B2) but now i noticed a little problem. my ram frequency is a little lower in cpu-z. Its 2394.1 instead of 2400 and also cpu core clock is at 4588 instead of 4600(core i5 12500) is this normal? for example margin of error for cpu core clock and ram frequency? i attached a picture from cpu-z
