BSOD with Memory Related Issues

[scottyseng]

I recently obtained a 9900K and a Maximus Formula XI board. I bought a GSkill 128GB kit of RAM (4 x 32GB @ 3600MHz C18) F4-3600C18Q-128GVK. 

 

I'm running in to constant BSOD errors regarding RAM (Memory Management, Unexpected end of stack). Any ideas on what may be the case?

What I've done so far:

Ran Intel Burn Test at maximum, Linpack Extreme at 10GB for 10 runs (then 30GB for 5), Cinebench R23 for an hour, and Memtestx86+ for 10 hours. These all passed with the CPU around 70-75C. I did update the BIOS to the latest BIOS, only loaded the ASUS recommended default (which does turn Multicore enhancement on) and used XMP 2 for the RAM profile.

 

However, I am running into issues where the PC randomly BSODs after letting the PC idle for some time. Now it's gotten to the point where windows will only stay open for 5 minutes before bluescreening. I read that the RAM may be overheating so I will put a fan directly over it and the VRM. I have even tried putting the CPU to stock stock (no Multicore enhancement) and no XMP (2666MHz) and it still crashes. 

 

I also note that the BIOS now refuses to post at all with XMP now stating "The System has posted in safe mode."

Test one stick of ram in a single slot on the motherboard rinse and repeat with different sticks and slots and see if the issue persists. Also is this a fresh install of Windows or is it the same Windows install from before your upgrades?

or it might be the IMc trying to run 4 sticks of 32gb at such high speed, 4 sticks of 32gb is even hard enough to run at low speeds, but at those speeds you are lucky if you can run it at those speeds, try to set XMp on and then manually set the speed to 3200mhz and try again

Will try one stick at a time, good point there. 

 

This is a clean install of Windows Server 2022 Standard (Yes, I run windows server as my personal PC OS). It also does it with Windows 10 when I was testing it. 

 

It would suck if the memory controller can't handle the kit. The whole reason of upgrading was to get more RAM.

It crashes with XMP off. 2666MHz.

Fixed by enabling XMP, but setting RAM speed to 3400MHz. No crashes since.

Edit: Sadly over time, it kept getting worse, with me only being stable at 2666MHz at the XMP timings at 1.37v on DRAM voltage.

 

I actually found a random amazon review that mentioned that the RAM stick order mattered, and that each pair of RAM needed to be on the same channel. Since this was a set of 4 from GSkill, the two on the top of the packaging needed to be in one channel and same for the other. I had to label each RAM stick, shuffle the positions, and I got it to post on 3600MHz on XMP (Which I could not do at all up until this point). I ran Testmem5 on anta777's extreme profile for two cycles (8 hours), Linpack extreme on 10GB for 5 passes, 30GB for two, Intel Burn Test at maximum for two, and it is running solid now.

 

More edit a few months later. The ram continued to act up and gskill confirmed the odd behavior was faulty ram. I rma'd the ram and it has been working great since. First time in my life I've run across faulty ram.
