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

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

Cheers will give that a try ?
EDIT
Gave it ago but didn't work, still dropped down
MCU 0x15 the right one?
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
-
It’s really easy, you can set AVX512 drop to 1, set your frequency 100mhz higher, open benchmark, reduce frequency 100mhz and let it run
i have to test a tool which prevents drop for AVX512 CPU on z690, if it works I‘ll upload it.

Yes, you need right value for this to get high Mem score but you must adjust voltages for Mem
-
With 8400 CL34 you will break 16k Mem score.
Can’t upload screenshots here now, but you can check screenshot from ocn forum ?

You can choose X6h bios and select necessary microcode direct in bios
-
try one of old X3 bios versions. I prefer X3c or X3k

For everyone who gets a Gigabyte Z790 Tachyon, here is some bios and tools.
As soon as my arm has recovered from the car accident and I can write more, more information comes.
Just as an info and clue, I don't set up high voltages:
My startpoint for Air and LN2
VCCSA: 1.25
VDDQ CPU: 1.35
VDD2 CPU: 1.45
Mem-Voltages:
VDD: 1.675-1.775
VDDQ: 1.535-1.635
Gigabyte Z790 Tachyon Bios:
Gigabyte Z790 Tachyon X4b (one of best bios versions for me)
Gigabyte Z790 Tachyon X6h (I've used also multiple times)
Gigabyte Z790 Tachyon X6k (have sometimes CB)
Gigabyte Z790 Tachyon X6m (with higher VCCIN Voltage)
Gigabyte Z790 Tachyon X6n (tRCD_WR added in Mem-Settings)
Gigabyte Z790 Tachyon X6o (Fix code "11" during memory training)
Gigabyte Z790 Tachyon X6U (Update for Gear4 mode, can be used for all benchmarks)
Gigabyte Z790 Tachyon X6V (Updated for Gear4 mode with lower bclk)
Gigabyte Z790 Tachyon X7b with different microcodes for 13th gen
Gigabyte Z790 Tachyon X7d (we have used it for max mem)
Gigabyte Z790 Tachyon X7J (14th Gen Support)
Gigabyte Z790 Tachyon X7L (14th Gen)
GIGABYTE Z790 Tachyon X Bios:
GTL Tools:
You can choose XP-Version for all OS

LOL nice buggy run Post right Screenshot for this score
-
93+ is a good one. My best 12900k have 94 with x4b bios (for 12th gen)
95 is my 13900k
-
If your CPU have good IMC 8400 are not a big problem. If IMC is ?, you can’t reach same frequency like some other ppl.
I’ve tested many CPU’s also for IMC, some of them can do it, some not-

With right settings for Mem you shouldn’t have any problems with boot with X4b or x6h bios. If they are wrong, boot will be a little bit longer. Try to play with voltages on it. Also SA voltage, with 12th Gen I always used 1.35v, with 13th Gen are 1.25v enough

With a-die 8k should be possible without problems. Can upload my profile later
