Asus z690 hero + kingston fury 64 gb ddr5 5200 -> very unstable with xmp i on - help

OS: WINDOWS 11 updated

GPU/DRIVER: EVGA Geforce RTX 3080 FTW3 - Driver: 497.09
MOBO/BIOS: Asus ROG Maximus Z690 Hero - BIOS: 0803
CPU: Intel i9 12900K
RAM: 4X Kingston Fury Beast 16 GB DDR5 5200

Guys, I'd like some help here.
I don't know what is happening.

I bought 1 kit with two RAM and 2 separeted RAM from Kingston. All of them are Kingston Fury Beast DDR5 5200.

I named them:
- RAM 1 - 32
- RAM 2 - 32
- RAM 3 - 16
- RAM 4 - 16
(32 because the RAM is from the kit with 2 of them)
(16 because it came alone)
(1,2,3,4 just to differentiate them)

Because of the blue screens (BSOD), crashes on games and so on, I started to suspect that the RAM could be the issue.
Since memtest86 is built-in on my motherboard I used it to try to spot the stick with the problem.

The results are in this spreadsheet that I'm using to organize my tests:

OBS:
[CPU] A B C D
AI OC is the AI Overclock from Asus.

As you can see:
- Testing all of them together, but with XMP I off, I got 0 errors on memtest86 (Test #1)
- Testing everyone individually, with XMP I on, I got 0 errors on memtest86 (Test #2, #3, #4 e #5)
- Testing "RAM 1 - 32" and "RAM 2 - 32" together (both came from 1 kit) and testing "RAM 3 - 16" and "RAM 4 - 16" together, with XMP I on, I also got 0 erros on memtest86 (Test #6 e #8)
- But on the test #7, when I put 1 extra stick (48 GB total), the memtest86 already found 5 errors in 3 minutes. FAILED.

I have a friend that has the same CPU and the same motherboard but with Corsair Dominator Platinum 64 GB DDR 5 5200 and he is using XMP I on with 0 problems.

Test #0 FAIL (It isn't on spreadcheat - I tested all of them with XMP II on) - https://i.imgur.com/47gj08y.png



What is happinng?
- Other members that are using this combination (Z690 Hero + Kingston Fury)... are they having similar issues?
- Is there a problem in combine RAM sold in Kits and sold individually?
- Is there a problem with XMP I and Z690 with RAM from kingston?
- Is there a problem with XMP I using 64 GB of RAM from kingston?

Xmp 1 and 2 on (4) dimms is not stable as of current. Will need to set it to auto and it will default to 4000mhz.

This is known issue, though may be a limitation of using all 4 dimm slots with DDR5 per Intel design specs.

Update your BIOS to 0811 then set your timings manually to 40-40-40-77 then DRAM frequency to 4800mhz and VDD voltage to 1.3v and VDDQ to 1.3v. Then for Asus Multicore Enhancement, set it to Disable - Enforce All Limits. This worked for me with all 4 RAM slots populated. XMP1 and XMP2 just cause system instability and BSODs when 4 sticks are installed

Do you also have Kingston Fury Beast 64 GB?

and the same motherboard?

I have a couple of Asus Z690 motherboard rigs. One has the Z690 Hero with the Kingston Fury RAM while the other has the Z690 Strix-E with G.Skill Trident Z5 RAM. Both machines using 4x 16GB sticks.

You saying "Xmp 1 and 2 on (4) dimms is not stable as of current." is because of some official statement or based in what you're seeing on the internet?

Mix n matching "kits" is never a good idea, especially when trying to OC it (which is what your doing when enabling XMP).....
For 64G try and find a 4*16G kit (all sticks within the same package) or better yet 2*32G kit....
