Long story short I bought what I thought was a good deal on some Mllse 6600s that wont run above 500 mhz. It appears to be some kind of mining bios flashed on the card.

Unfortunately I do not have the correct bios and after doing some further research it appears that although they report as 6600s in GPUZ when you look on Aliexpress they look identical to the ones listed there as 6600m.

I dont care one way or the other they both should clock above 500 mhz and play 1080p fine but for the life of me I cant find a bios that matches that will unlock them back to the way they should perform.

Just throwing it out there hoping someone who knows more than me can point me in the right direction

Please remove the cooler and share the pictures of the PCB with us. One large picture as well so we can compare the PCB with other cards

Interesting threads about the same card:

This bios should be the correct one. Don't forget to make a backup before flashing.

Follow this post (on another forum) for flashing at own risk:

Sorry It has been a while since I have flashed a video card but isnt that the same clock speeds Im trying to avoid? It says 500 mhz gpu. . . These are supposed to clock up over 2000?
