DCLARBK means Dual Channel LAncer RGB Black. Without DC is only one kit. DCLARBK also appears as M Die on Asus, but it depends on manufacturing date. New kits are A Die.

So, since disabling CO, my RAM overclock is completely unstable now. I'm at a loss as to what to poke next. Just threw an error code 4 in 1usmusV3 which seems to point at too tight tRFC, so I guess I will reboot with that slightly loosened.

Looks like you are running 4 DIMMs. ODT settings play a big role with 4 DIMMs.
Try:
ProcOdt: 48
DramDqDs: 34
RttNomWr: 40
RttNomRd: 40
RttWr: 48

Error 12,0,2,10 spamming TM5 in minutes. This all stemmed from yesterday I wanted to try out Project Hydra for CO testing (so I turned off my bios set CO, which was only -15), had a couple full system reboots during testing....I wonder if it corrupted my bios somehow.

6400MT/s with 4x16GB? I thought it was impossible :|
Which works better, 2x32GB or 4x16GB?

Was -15 on all cores stable? I have my two preferred cores at 0 and -4. Tested each individual core at -30 (only 1 at -28) in SSE and AVX and they worked for 12hs+, but my preferred core cant go lower than 0 with AVX2.

Sorry for the off topic

Passed occt cpu small/avx2/extreme, so it seemed stable enough for my purposes.

6400 fclk 2133 64GB, vdd at 1,4V, seems a bit low.... I would start there

Could be memory training issue.

I'am also using X670E PG LIGHTNING.

My 6K C26 timings was rock stable @ 1.52 VDD. But after flashing 1.20/1.21 BIOS its pure luck right now.

Its only stable 1 out of 10 boots. Other 9 boots gives MEMORY_MANAGEMENT BSOD.

Yea, you pretty much have stressed every timings with the given VDD 1.4, and VSOC 1.3. I tend to believe it is the VSOC 1.3 not enough. Even with the same VSOC on the old bios, the motherboard might add 50mv secretly in the past. You never know. Try 2000FCLK. If it works, work it back up. If not, try 6200MT/s instead.

I'm going to give this a shot, running a quick test with no ram OC to make sure it's not a borked cpu (somehow?).

Maybe you need an Intel forum?

You can increase the VDD to 1.66 - 1.68 and put on water cooling.
high voltage and cold water will do the trick.
But it makes no sense to increase the frequency strongly on the Intel for games. It is better to take 32GB x 2. 2 ranks. More memory banks will always be faster in games than one rank and high frequency. DualR 6800mhz vs SingleR 32gb 7800mhz

I definitely would not run for 8800-9200 memory. Buy a motherboard for a thousand dollars and buy / sell 5-10 processors in search of a good memory controller. It's just ridiculous to tears.

* ps

If your memory controller is crap, all that's left is to sell the processor and buy a new one so that the RAM is overclocked :D

Welp. I give up. Went back to xmp which oddly is about 4-5ns slower than it was when I originally used it for a baseline.

edit: interesting observation TM5 1usmus continues to dump memory on test 11 with xmp and that's all.

Download TM5 again, re-extract it and run again. @Veii mentioned that TM5 can get corrupted
