I have the Extreme, but at default settings with no XMP or anything something probably is cooked, considering Karhu threw an error after 7 minutes?

Edit: now I've been running XMP Tweaked with 8000 for nearly 2 hours with no mistakes. I'm seriously confused at this point, Karhu finds issues at stock speeds within 7 minutes, same if I use a memory preset as you suggested earlier, but XMP Tweaked with higher speeds and better timings hold much longer, and in the current case of 8000 are even still going. @Silent_Scone 

Edit 2: I've passed 3 hours with the 8000 now. Can I rule out faulty RAM / hardware, was Karhu failing with stock 6400 a false positive maybe?

[Silent_Scone]

If the system passes Karhu at 8000MT then the DIMMs are not faulty. I'd aim for 4-6K coverage, more than enough for a gaming rig. 

Karhu certainly should not be throwing errors if the system is at Optimised Defaults. Check CPU mount, and if you're using a CPU contact frame revert to the original retention mechanism, or ensure it's not over-torqued.

[markusm]

Thanks, but I don’t have a contact frame and if the mount or CPU were the issue, why would Karhu then not throw an error with faster speeds? 

CPU mount seems fine otherwise. @Silent_Scone

Random result? To avoid this you would have to run the same test probably a dozens of times.  And also, because Karhu is running from within the OS, I think there will be at any time a small portion of the memory it can't access,  because it is in use by the OS itself. I still wonder how your memory would deal with the IMC torture test in P95. It's also running from within the OS. But running the IMC  test for 1 hour without getting "warnings" or "failures" , has always indicated stable memory for me. It is certainly more demanding than MemTest86, and it is testing the memory in the context of the entire system. 

At the end of the day, I think for overall system performance, the CPU ist more relevant than running the memory at 8400 or 8800MT.  For Arrow Lake tuning the E-cores or D2D and NGU has more impact than squeezing out another 400MT  from the memory.

[markusm]

Yeah, I'll leave it where it is at 8000 for now, cleared Karhu for 3 hours, followed by 90 minutes Indiana Jones. I had tried Prime 95 following your suggestion the other day, I believe I was at 8200 and passed that for 15 minutes.

Another reason to love my APEX. 😍

Updated to the 1602 Bios for my Asus Z890-A. Ran into a bug, and wondering if anyone else experience the same issue.

Bug - Sync All core for Pcores stopped working. Was working in 1501 Bios. Using the same settings for both BIOSes.

I ended up reverting back to 1501 bios just in case.

[SBLive]

Works fine on my Z890 Maximus Extreme. My P-Cores are synced at 55x.

Ok, so I finally mitigated the issues with the 1602 Beta, I actually applied the BIOS update again, after clearing CMOS, and finally have keyboard and mouse detection in BIOS again, and the error setting traits on provider issues seem to be clear as well thank god, there always seems to be some weird USB related issue, I did also manually install the latest ME, and Chipset drivers (again)

I simply could not get the G.Skill 8800 CUDIMMS stable on my Z890E. I am going to RMA them, I am sure it is something to do with the RAM not being in spec, otherwise it would not be on the QVL for my motherboard. It would be a worse thing to believe that QVLs are released which don't account for XMP settings. These are gamer products, how do they think people will use the parts?

I could not even get it stable at 7600. I had to drop it to 7400 to get it stable and at that point, what is the purpose of CUDIMMS.

Interestingly, I replaced it with brand new CORSAIR Vengeance RGB DDR5 CUDIMM 48GB (2 x 24GB) DDR5 8000MHz CL38 1.40V (CMHC48GX5M2X8000C38).

These sticks worked perfectly, at a higher MTS than the G.Skill, lower latency and lower power consumption. 5000%+ in Karhu. They are Rev. 4 M-Die's I think. Also on the QVL for my motherboard. Will be sticking with these for now.

It is not as simple as high end kits won't work on 4 DIMM mobos, as I am running 8000 comfortably on mine now. But the higher you go the more expensive the kit and the more diminishing returns. At some point up the chain only an Apex will work anyway. Find a sweet spot, then as others have said move on to OCing other components.

This whole launch has been one big disappointment, but I'm hoping this platform, RAM and motherboards can age like fine wine with further updates, enhancements and the refresh which will be released later this year or next.
