Does anyone have any profiles they would be willing to share with me ? This is my 5th 13900k and only one able to boot above 8000 on this board. My 12900ks had a much nicer IMC. For me it seems leaving my SA on auto results in no boot. Playing with the new 8000 lumi daily profile. I have to set the SA at 1.25 to boot up. In memtest lots or error 2 and 6. Which I believe is IMC and poor voltage timeout.

I just moved to water ;p using the 6400 g skill a die kit. I also have a Gskill 7800 aide kit that I want to return if I can get this one 7800 + stable. Theoretically if it boots there should be a way to stabilize the frequency right ? Using the byski kit with Arctic thermal pads.

I actually have gotten 7600 stable on air, since I switched to water I’m still stuck ;p using your info though to tweak my 7800
Profile since I played with the Pl and mc im actually getting 7 min into occt without error temps hitting like 40c. I usually use tm5 and occt. I will switch to y cruncher though!

I’ve been playing with your profile mr.fox all week. No luck ;p

Yeah don't you just love the silicon lottery? It really sucks.

You have M- or A-die?

A die, 6400 g skill and 7800. I think it’s my 13900k. 12900ks was much easier to get stable for me.

Yes it could be the CPU, but it could also be the memory. I returned two kits of A-die that were garbage and I RMA'd my way through more than a half dozen kits of M-die that were junk. The A-die kits with a default SPD clock of 4800 (vs 5600) were rubbish. The two M-die kits and one A-die kits that were good enough to keep were generic green Hynix modules with no heatsinks or RGB puke.

If it seems to be stable but errors out after a number of minutes of memory stability tests it may be overheating. If your memory exceeds 45°C you will begin seeing memory errors during tests. Unless you have a hotbox case, having a fan blowing directly on the modules should keep them below that temperature.

The memory is water cooled on my Dark mobo. On my Asus setup it is air cooled. If I turn off the fan on the Asus I error out on memory tests. It passes stability tests with the fan blowing on them.

It depends. I notice you use tREFI max. That might be part of it. I’ve been able to run ABSOLUT on 7600 up to 50.5c (it equalised).

Mr. Fox
The additional 8 E-cores probably has an influence. My overclock capacity (both core and memory) was slightly less with 12900KS, but easier to stabilize with fewer cores. Hard for anyone that doesn't have dozens of samples to compare, but it seems logical. Motherboard, CPU and CPU IMC, and memory silicon quality variance among samples throws too many wildcards into the mix. I've seen examples of CPUs with really high SP ratings that overclock the cores easily with low voltage that suck at memory overclocking. When testing memory (and returning the numerous garbage samples) I kept everything consistent except for the modules. When the memory did not overclock well, I would retest it in my other system and the bad behavior followed the memory to the other system. The good modules performed well and were stable on both systems.

interesting.   Question.   Can different memory kits rated same speed pass where others won't?   Example would be a 7800 kit that will pass at 7600 and not at 7800.   Should I try another 7800 kit?   And believe me, I've tried everything to get 7800 minus taking the e-cores out of the picture.  Might try that and see what happens.   7600 is plenty fast but I haven't been able to get xmp or manual settings for 7800 yet.  I get it that it could be the IMC, but want to rule out the dimms

I finally received the Trident Z5 RGB DDR5 8000J3848H16GX2-TZ5RK, but I am unable to successfully boot after loading the XMP profile. I am currently using EVGA Z690 DP (bios 2.08) and 13900K with an AIO CPU cooler. I also tried the various OC profiles that come with the BIOS, but none boot. Any help would be appreciated. Thank you.
 
 Update: Trident Z5 RGB DDR5 8000J3848H16GX2-TZ5RK XMP profile 1 works with i9-13900KS on an EVGA Z690 DP (bios 2.08) and an AIO CPU cooler, so my initial issue was inadequate processor IMC.
