Z690 Hero Bios issues with gpu

[Undertoker]

Hi guys
i need some help before i throw this damn hero board in the bin in anger and frustration - please

The troubles began when i upgraded the bios from 811, 811 was fine, 803 was fine , 811 was fine
with 1003 the gpou ran really poorly, so i rolled back to 811

But since then every bios update above 811 i try as they release slaughters my gpu performance and i cannot understand why.

If i roll back to 811 the gpu runs as it should and back at full speed.

Ive tested this with both synthetic bencmarks and gaming and the gpu is around 60% of what it should be in any bios higher than 811....

My system spec is as follows
12900KS
Asus ROG Z690 Hero Motherboard
Asus ROG Strix 3090 OC Gpu
32GB G-Skill Trident Z5 @ 6000mhz
Thor 12000w PSU

Windows 10 64 bit

Ive tried the gpu in another machine it is fine, its just on this damn hero board when i run a bios higher then 811, 803 is also fine.
But any bios above 811 simply cripples the gpu

Ive tried two different 12900 cpu's one a K version and the other a KS both see the same issue, the CPU's run fine its solely the GPU with any bios above 811.

Im not sure what to do to sort it, ive even formatted and deleted the partitions and start3ed over reloading a totally new OS
It still wont let me get anything more than about 60% of what my GPU should run at i just dont know what to do to resolve it

To give you an idea i run Pubg for example at 3440 x 1440, ultra everything and i easily get 180 to 200 fps, now i hover around 90-100 fps
When i run Timespy extremem i usually score around 18-19 k on the GPU using bios 803 or 811, but with any bios higher it down to between 9 and 11k

Now i am running a 12900KS cannot roll back to 811 bios because that doesnt support the 12900KS, itll only run at 5.4Ghz, with the newly released bios of 1403 the cpu does as it it supposed to do - at the expense of losing about 40% of my GPU performance.....

Now i dont want to throw this Hero board away - but i am very close to doing so and im very reluctant now to buy another Asus board in honesty as ive found this 12th gen to be nothing but unstable aggro frankly with this Asus board , it doesnt like running memory as it should and now the GPU runs like a snail, unless i roll back to 83 or 811 and the GPU runs fine.......

Does anyone have any ideas please ? Ive so far spent around 20 hours trying to fix this and gotten nowhere but bloody annoyed

Thankyou in advance

You might look at your GPU overclocking settings, here are my scores for timespy and cinibench with my overclock on GPU settings, Note I manually overclocked my CPU in the BIOS to 5 GHZ based on my cores ASUS performance predictions instead of using AI:

BIOS: 1403
Timespy: 19212
Cinibench (Realtime): 28140
MSI afterburner config:
- power: 100%
- Temp limit: 83
- Core Clock:+0
- mem clock: +100
- fan speed: 0 (water cooling)

P-cores by core overclock to 50 (limits set 51 for my best cores and 50 for the rest)
e-cores: 40
Vcore: 1.328
negative offset voltage: -0.100 (this is to keep the temps below 90c)
Corsair dom 5200ghz (2x32) CL 40 XMP 1 - with manual set OC by DIMM in bios

this is Stable for me and get around 140 FPS in COD warezone on a 144hz untra wide 49 inch monitor
