Still using R6E - random hard lock-ups with 8× RAM; any fixes without removing sticks?

[Thireus]

Hi all! I was one of the early adopters of the Rampage VI Extreme and I’m still running mine today. For a long time I’ve been fighting random hard lock-ups: the system just freezes solid (no BSOD, nothing) and it happens irregularly — anywhere from about every 24 hours to once every couple of weeks. I’m running 8 sticks of RAM (full population).

This exact problem has been described by many people in this thread: the OP and others reported the same behaviour. I’m so glad that after all these years people finally identified the root cause.

My question: has anyone actually resolved this while keeping all 8 sticks installed (i.e., without removing sticks or dropping to fewer DIMMs)? If you did fix it, what exactly worked - BIOS version, settings you changed, memory kit/model, or hardware swap (RMA board, different CPU, etc.)? The original topic got locked and I wish I’d found it sooner, so any up-to-date advice or personal success stories would be much appreciated.

Thanks

I have not found a solution for 8 sticks. The only way I got the system stable was to keep 4 RAM sticks on the left side of the CPU and nothing on the right. Tried all newer BIOS since we discussed this 2019-2022 in this thread https://rog-forum.asus.com/t5/rampage-vi-strix-x299-series/asus-rampage-vi-extreme-ram-problem/td-p/... . But in the end only 4 sticks on right side works. I bought a R6EE system (back in 2020 I think) and that worked flawlessly.

Im using this mobo with 10900x and i have 7960x both all memories working 4left 4 right without problems

Thank you for the replies guys.

Interesting @PanosXidis24. Do you often turn it off or make it sleep or leave it always on? Mine never sleeps for weeks. Only times I restart it is when it freezes. And may I ask what kind of RAM you have and if you were an early adopter of this motherboard?

Edit: btw, over the lifespan of this motherboard I have used 3 different CPUs and 2 different GPUs, only thing I have not changed is the RAM (G.Skill F4-3200C14Q2-128GTZS). Freezes happen even at stock, even using non-XMP profile. The fact that they happen infrequently after the computer is always on (not even sleep) for days and weeks makes it near-impossible to troubleshoot.

you have 128GB RAM theres one tool the name is Coffeetime 0.99 on this program you have unlock 128gb!but im sure 128gb ram is working 100% you can check your memory ram with memtest86 one by one or karhu!! @Thireus

What memory model and make do you use to make it work with all 8 sticks of RAM? G.Skill? Corsair?

I use: G.SKILL TridentZ Series 128GB (8 x 16GB) DDR4 3600 (PC4 28800) Desktop Memory Model F4-3600C17Q2128GTZSW

and that randomly fails with all 8 installed. have to remove the 4 on the right side and then it works.

CORSAIR Dominator platinum 3000cl15 is samsung bdie version 4.31

@PanosXidis24, sorry I didn't quite understand what you mean by using a program called "Coffeetime 0.99"

I suppose the kit is this one: https://www.corsair.com/us/en/p/memory/cmt128gx4m8c3000c15/dominatora-platinum-rgb-128gb-8-x-16gb-dd...

Hi 😊 👋 

1. Do you testing your GSkill 128GB with other board yet?

2. For G-Skill CL-14 kit I think they 'll need more VDIMM and VCCSA than my CL-16 a little bit such as 1.4V VDIMM and VCCSA 1.0 to make sure see manual again 

My 64GB CL-16 kit working on VDIMM 1.35V VCCSA Auto 

3. You may need to update your R6E with latest Bios 4201 version .
