7900xtx flash just OC bios

[MrDeed5]

Late to the party lol. I just ordered my ch341a programmer and adapter. My red devil 7900xtx silent bios is borked trying to flash the aqua to it. I just wanna know how to tell which is my silent bios in the software since it has 1 eeprom and it has both bios' on it. I don't wanna touch the OC bios. Thanks in advance

since it has 1 eeprom and it has both bios' on it.

That actually shouldnt be the case. I have never seen any gen share the chip. I have seen 1 chip be on the front of the PCB while the other is on the back, but not the same. Infact this person that seems to have successfully flashed his and is helping others heree: https://www.overclock.net/threads/official-amd-radeon-rx-7900-xtx-xt-owners-club.1802706/page-208 Also seems to mention "both" chips.

As for how to tell. Im not sure; never looked into the 7xxx series vbios's. You could probably use a simple hex editor like HxD and compare your dump to one from the data base here for your exact model card and see the differences if they are indeed on the same chip.

From an AMD and Nvidia standpoint the roms are dumped raw (no partitioning or formatting) so you could download the vbios you need and flash it.

I hope you will manage to fix the card by reflashing the original silent VBIOS on the proper chip.

I know you may not need this kind of advise now but the Aqua BIOS is pretty much useless.
Makes the GPU to pull 550W and the performance gains is marginal (+1~2%) over the more conventional performance VBIOSs of 450~460W.
My XTX can go up to 467W but it does not worth the power and the heat above 400W. I keep it at 382W max.
550W on a GPU that meant to be a 350W one... sucks
Sucks power and sucks in general.

Start with a gpu-z screenshot, then go to advanced tab and select BIOS or AMD BIOS on it, if you see memory timings select that too, post pics from both. We need to know your specific part number of the pcb.

Yeahhhh, no. If you saw only 1-2% gain on your card with the extreme bios, is user error...Or your card is borked.

Its a massive upgrade, and with it I was able to hit 40k gpu score on timespy on 550w asrock bios, And the memory was able to clock a fair bit higher using asrock bios. There are many many many 4090s that have a lesser score than40k gpu on timespy btw...., Stock I hit 35k gpu score on Timespy with 463 watt bios, (This is on xfx 7900 xtx black ed.) Stock cooling with ptm7950 on core and upsiren pro on mem. here is a quick comparison between the two using 3dmark comparison tool:



Clean 14.4% increase, Way into 4090 territory...


Here is card with clamps on it:

So yeah dont listen to this other guy.. Its massive upgrade, if you're afraid on using clamps go to overclock.net 7900xtx/XT owners thread there is a method to flash the bios without the clamps at all, and just using software, but it isnt the easiest.. I've used it to sucess myself. And I've used clamps. On my XFX I believe the front chip like you see on my pic was silent and the chip on the back was performance, Because the switch towards the IO is silent and the switch towards the power connectors is performance IIRC, your mileage may vary though, cant speak for every card.... Once you have the clamps hooked up or using amdflash you can dump the bios of each and figure out which is corrupt and then you'll know

Thanks for the response. My ch341a comes today and I'll take it apart today. I read somewhere from someone there was only 1. I could flash the stock oc bios on one and see if that fixes it. If not I'd assume it would be the other eeprom that is silent.

I'll be using the clamp that comes with my ch341a, I used the newer asus version of amdflash and it didn't work even though it said flash successful. I even tried flashing the silent bios back onto it but still nothing. Only boots on my OC bios, don't wanna touch that bios in case I mess something up again.

I believe the front chip would be the silent on mine too. Was hoping it would be the one on the backplate so I wouldn't risk ripping my cryosheet lol.

I was able to flash to the normal aqua bios but it won't let flash to the extreme using the asrock tool. Any suggestions?

Then, I don't think you quite got it flashed w/ the base Aqua BIOS.
Once the base Aqua vBIOS is on the card, the card 100% IDs as an ASRock card, and the update tool 'just works' (in my experience)

Even tho it's supposed to be impossible, after EXTENSIVE fiddling w/ ATIflash versions and combining ASUS' provided ver. w/ one off TPU
I was able to software flash my NITRO+ with the Aqua BIOS (and use the ASrock 550W update tool) *and* crossflash my friend's 7900 XTX Pulse w/ my NITRO+ vBIOS.

On my particular 7900XTX NITRO+ (On stock Air Cooling), the improvements were seemingly unimpressive. I lost patience in trying to 'tweak' further and just switched the vBIOS switch back to the NITRO+'s.

I got it figured out. Had to do it in safe mode. Tip 9% 3dmark with my hardware now. Insane.

9% in 3Dmark for 25% more power and in games would be even less than 9%. More like 2-3% for 25% more power.
If anyone is doing this for the bragging rights, by all means… But for actual gaming performance does not worth it.

Idk, my graphics core went from 29576 to 35853, and I still have plenty of thermal headroom. I'm seeing about 25 more fps in marvel rivals at 4k max settings.

How did you flash it? Can you provide a guide?
