new V-Bios, same like in G.Skill comp thread, is in the first post.

since a few versions of intel chips it`s not longer possible to adjust RTL`s manually in memory settings. Only with different CL and frequency it´s more or less adjustable. For example, CL32 and 8k on mem you will get 59/60 or 60/60 RTL`s als long as you have activated RoundTripLatency in memory training options. In this case you`ll get tight RTL`s automatically And yes, it`s sometimes very hard to get 100% stable frequency for mem, because each board, cpu and mem are different. also cooling is important. As soon your memory will be warmer as before, settings are not stable. For stability is also sometimes necessary to adjust a little bit VCINN and the third VPP A0 voltages. 0,02v more are sometimes very helpfull

I would use X6o ?

It works but I also wasn’t able to go over 9100, import are timings and voltages. If Mem VDD and VDDQ are to high, system don’t start

Which CPU do you use? I don’t have any problems with 0x15 and 12900k

0x15 microcode and AVX512 only possible with 12th gen CPU`s

Is it also ok for bios availability if it is in Mainboard thread? how does it looks with modification of available bios? Allowed like last time?

For stability are many things important. For example voltages. If you have it @“auto” check you stable voltages with Hwinfo and set it manually in bios. Same is also necessary for timings. This low tREFi you have only after loading setup defaults. Different CPU’s and Mem need different voltage/timings settings. Sometimes are lower voltages for SA/CPU_VDD/CPU_VDDQ better for Mem OC ?

Have you played with Round trip latency? I’ve never seen that RTL’s are different after reboot without changing something in Mem-settings. lower CL value is connected to RTL’s and also depends on Mem frequency. If you want higher RTL’s, disable round trip latency in memory training area and don’t leave it with “auto” settings

It’s not possible to enter RTL’s manually. If your RTL’s are too high, please set “Round Trip Latency” to “Enabled” after it your RTL’s are tight.

New bios with correction of postcode 11 during memory training is in the first post

New bios wich postcode 11 fix is in the first post

Glad to hear it mate!

If you want to update all bios versions together, select first bios and the switch for bios must be on position “1” put your bios on fat32 usb drive and rename it to gigabyte.bin. After it flash it with q-flash button on the AIO side

yes, MCU 0X15 check first post, I`ve uploaded tool to prevent AVX512 drop. couldn`t test it at the moment but this one helps me on Z790

You must disable all energy saving futures, you can see it in your screenshot already. P- and E-core frequency dropped down
