Hi,
My PC specs are the following:
i7-12700KF
ROG Strix z690-f Gaming WiFi Motherboard
32 (2x16) Corsair CMK32GX5M2B5600C36 Vengeance memory
I recently purchased G.Skill F5-6000J3040G32GX2-TZ5RK to replace the corsair memory to have a total of 64GB of ram.
However I'm finding when i try and run XMP1 or XMP2 at 6000MHz, i get errors when i run Memtest.
I tried the scaling the frequency down to 5800MHz and 5600MHz, and I'm still getting errors when i run Memtest.
I don't seem to get errors in Memtest if i run it at 5200MHz or 4800MHz.
This memory is listed on the QVL for this motherboard so I'm not sure why it's not working at 6000MHz.
Is there any reason why this would be happening and is there any other settings i can adjust to get this working?
I really would like this to work at 6000MHz.
Any advice or help is appreciated

try using 1 stick of ram and see if 1 works while another doesnt. that would indicate a faulty ram stick.

I did as you suggested,
I ran one stick in slot 2, set it to XMP 1 and let it do 4 passes in Memtest. it passed without any errors (first image below)
I took out the single stick and replaced it with the other stick (in slot 2) and left all the settings the same ie XMP1.
I'm up to test 9 in the first pass in memtest and I already have 22 errors (second image below).
So the first stick gave no errors.
The second is giving errors...
I'm guessing that means the second stick is faulty?
edit: I ran both sticks in slot 4.
Surprisingly the first stick got 1 error after 4 passes and the second stick got no errors after 4 passes!

Hello sterps316
I have almost the same setup as you.
ROG Strix Z690-F Gaming Wifi
i7-12700KF
16GB (2x8GB) Kingston Fury Beast DDR5 6000MHz 40-40-40-80-2T
ROG Strix 3090 Ti LC OC
Seagate Firecuda 530 1TB
EVGA 1600w psu
Your G.Skill memory part number shows it's a 64GB (2x32GB) 6000MHz CL30 memory kit.
For Z690, G.Skill shows only the ROG Maximus motherboards on the QVL for that memory kit. Plus, Intel 13th and 14th Gen cpu's. The CL30 is probably what is putting a hurt on the 12700KF's cpu memory controller.
With 16GB, I'm able to overclock my memory to 6200MHz 36-36-36-40-2T.
Hwinfo shows half the frequency, 3100MHz = 6200MHz.
Click the pic to make it bigger.
Here's what I'd try.
1) Enable X.M.P.
2) Scroll down to Dram Timing Control and click it.
3) At the very top of the Dram Timing Control page are the primary timings, they should look like this:
30
40
40
96
Command Rate - Auto (should be 2N)
4) Set them to:
40
40
40
96
Command Rate - 2N
5) Hit F10 and Enter to save and exit.
See how this goes and take it from there.

Thanks for this.
When i run a single 32GB stick as XMP 1 profile and do a memtest, it passes.
Currently running the second 32GB stick on its own with the same settings, I'm up to 27 errors in memtest.
Could this be the timings that you've mentioned that I should change, or is it more likely i have a faulty stick of ram?
Settings might come in handy though, so I'll keep them in mind.
Can I ask, how you know what numbers to assign in the timings?
This is new to me.
edit: I ran both sticks in slot 4.
Surprisingly the first stick got 1 error after 4 passes and the second stick got no errors after 4 passes!
edit2: I tried what you suggested by manually changing the primary timings with XMP enabled. Unfortunately i still received errors.

Hi @sterps316
Are you using a CPU contact frame?
Increase VDD/VDDQ by 40mV on the second stick that was failing and retry Memtest.

@Silent_Scone Is that the latch that locks down against your CPU?
If so, I'm just using the one that came with the Motherboard, I have an AIO cooler attached to the CPU.
I ended up testing both sticks of ram in slot 4.
Surprisingly the first stick got 1 error after 4 passes and the second stick got no errors after 4 passes! Which is the opposite of the first result.
