Modified RTX3000 series BIOS files with memory channels disabled

[benwaterson]

Hi All

I was looking for ways to disable memory channels in BIOS for a GTX 980 (found nothing) - however I did find a load for RTX3000 series cards - file name describes which memory channel is disabled and for which card - maybe of use to someone with a card that has a bad memory controller (and ram chip is good) to get the card running again with slightly less RAM.

They look to be from Gigabyte cards originally.

I've been looking for the same software for a gtx 1080 ti
With one bad Chanel.
Sure there must be some way to disable a chip by moding the bios/ firmware.
Anyone when to add to the topic?
Thanks

looking for the same in a 3080ti with a bad ic . it turns out its the E1 chip location but may have bad connection under the core. im not tryint to reflow it with my skill. dont mind a cheap 3080ti with less memory. it was cheap

Anyone know if these 3060 bios files are for the 8 or 12 gb versions of these cards?

Work on 3080 Lhr versión?

Curios where these came from. Looking for one for an rtx 2070 and hoping modified files for the 20 series cards are also present wherever these were found.

great resource, got my 3090 to work which had broken pads on channel B.
Is there is a similar trick for 1080/1080ti to disable memory channels?

if these are from gigabyte originally how can we adapt and write these into other brands like PALIT which is also LHR?

Is there a rom available for the 3080 LHR?
