Did some research last night and apparently tr4 has issues with running 128gb of RAM. I'm going to attempt to manually set the RAM in BIOS and will let ya know.

Ok understood and thanks cw. I'll wait a bit for some of your comrades to hopefully chime in and start looking at chips.

Got another BSOD as I was attempting to respond to this. Here's the minidump. It now definitely seems to be tied to those memory slots. But first I'd like to describe the sequence of events that led...

Ok I've populated A1, B1, C1, D1, the BIOS reads quadruple channle and the system boots fine. I'm going to initiate a GPU render and see what happens. Do you think this could be a CPU problem?

Nope I surely didn't and will try here shortly.

Got a BSOD. UNEXPECTED_KERNEL_MODE_TRAP caused by amdppm.sys. This latest occurrence is typical: late at night when the system is idle.

Here's the minidump.

Some things to remember are that...

OK I reinstalled all RAM, initiated a GPU render and the system is still running strong as of last night. Any final thoughts? Tests?

Ok thanks for the detailed response CW. I've updated the mobo to the latest BIOS (3.3), will reinstall all 8 DIMMs and see what happens.

Ok understood CW. Could it be possible that even though the memory used is in the QVL list for the motherboard that it would still cause BSODs? I don't really feel like futzing with Memtest so would...

Hey cw I'm not sure what you're saying. Test with memtest86 to confirm the speed at which it's running? Also where are you ultimately going with this?

Okydoky I removed D2 and the BIOS shows the RAM operating in single channel. CPUz shows "Channels # - Triple" however. See image. Thoughts?212081

Ok fair enough, I'll start with D2 and I do have CPU-Z I stalled.

On pg21 of the manual:

"If only two memory modules are installed in the DDR4 DIMM slots, then Dual Channel
Memory Technology is activated. If three memory modules are installed, then Triple ...

Ok understood CW. Which do you think I should do first? Triple channel test or update BIOS?

I'm back and I switched RAM sets. Interestingly enough I had to replace my Liqtech 360 because the pump died. I replaced it with the Liqtech II 280 and at almost 24 hrs of uptime I'm getting decent...

Up-time is addictive. The project I'm currently on is currently ramping into high gear and given that I havn't had nary a single BSOD since the extraction I feel I need to continue working as is...

Haven't noticed a difference at all. I invested in the full 128gb for multitasking (running After Effects and C4D concurrently) as well as longer RAM previews in AE.

Okydoky we made it to Tuesday morning. As I'm in the middle of a project now I think I'm going to try the other RAM group on Friday evening. This up-time is nice... :)

No BSODs as of this morning and now going about a regular work day with fingers crossed.

Okydoky I've been running since this morning on half RAM and so far so good. If I'm BSOD free tomorrow morning then there's a good chance it's the other group of RAM and I'm thinking 48hrs (or...

Yes it does and thanks. I'll dive into the manual this weekend, create a strategy based on your suggestion and report back when appropriate. Thanks much.

Interesting... Can you describe "...in such a way that preservers the dual channel configuration of the remaining memory..." in further detail please?

Regarding if I've been able to reliably reproduce the crash, the short answer is no. At one point I thought I had traced it to the initiation of a GPU rendering session however after doing a complete...

Hey guys I'm back and am going to plan on using Spectrum's DIMM testing strategy above. Given that I've Furmarked (per instructions) each GPU (of which ther are a total of 4) and am using a brand new...

Hey Spectrum thanks for your suggestion. It would be prohibitive for me to test RAM at this time using either your strategy or to test in one session. After the current project I'm on wraps I'm...
