When I put 4 memory modules together then my memory speed is only 4000! This is below than the official level, Kingston says MINIMUM 4800, Intel i9-12900KF CPU says NON OVERCLOCK 4800, Asus ROG Strix motherboard says NON OVERCLOCK 4800. When I did memtest with 4 modules together I got always a lot of various memory errors. Do you know why? Because when I do memtest with the same single or double memory modules I do not get error in the memtest.
I have only 2x16GB memory in the A2+B2 slots, the many hours long memtest was OK in default settings
According to the QVL list, the promised XMP 6000 and even the XMP 5600 does not work at all!
In BIOS in the XMP list, these settings do not work:
These settings works:
default 4800 (40-...)
XMP 4800 38-38-38-70-1.10V
If I choose XMP list (6000 40-40-40-80-1.35V) then I change only the Mhz:
XMP 5000 40-40-40-80-1.35V
XMP 5067 40-40-40-80-1.35V
XMP 5200 40-40-40-80-1.35V
XMP 5400 40-40-40-80-1.35V
XMP 5600 40-40-40-80-1.35V (it was a longer black screen in the first time to set up this)
So (XMP 5600 40-40-40-80-1.25V) does not work, but the slightly modified (XMP 5600 40-40-40-80-1.35V) works.
But later I got many blue screens at 5600, so it does not work at all.
I set up this in the XMP list: (6000 40-40-40-80-1.35V)
Then I set up the other suggested settings:
Set CPU System Agent voltage to Manual then type in 1.35v
VDD voltage - 1.40v
VDDQ voltage - 1.40v
IVR Transmitter VDDQ voltage - 1.40v
Memory Controller voltage - 1.35v
Then I got all the time various Windows crashes during the Windows load.
In any case still I have 20-second black screen time before BIOS screen appears. Is this normal?
It seems the promised advertised things does not work at all, just they ask more money for functions that does not work. I do not know what is the problem, the CPU or the motherboard or the Memory. Because if I would know this I could buy cheaper stuffs which could works on the same lower speed as the expensiver premium stuffs works actually.
Ok, I see that 4x16GB is not in QVL list, that is why errors and 4000 speed. But I do not see any "4x" or any "4x32GB" or "2x64GB" on that list, which means the advertised max 128GB is unrealistic and the 4 DIMM slots are a useless joke. So I understand this, 4 rams do not work, this is shame.
I plan to buy a ram from the supported list maybe KF556C40BBK2-64 2x32GB 5600, and this is much cheaper than 4x16GB 6000 was, and I found a very expensive G.Skill 6000 2x32GB, but this is unnecessary.

There is ppl running 4xXX sticks , you can check either youtube ( one guy has a vid that said to change the setting "sync all pmics" to the other setting that pmics are separate), also check overclocker forums.. I dont have link to the vid or the forum posts here. But i would try to get 2xXX working first , then try 4xXX with lower speeds if you need to .
Hello ! How is your progress on this case? I have almost the same component configuration as you. I'm just trying to run another memory with 4x16gb G.SKILLF5-6000J3636F16GX2-TZ5K .
As for short-term fan noise, I also noticed this, and not only when loading Windows. Especially when I switch Intel AI Overlock.
Now my master is trying to test the processor (12900KF) and possibly make an exchange. But I also have a suspicion on the motherboard (I have the same as yours). The only thing that differs for us is the error code, it basically gives me IRQL_NOT_LESS_OR_EQUAL.
In single-channel mode, the system works OK, but in dual-channel memory mode it fails either immediately or after some time. I don’t know how it will end, but I want to believe that general reason in the processor, not the motherboard, and they will change it for me.
