:: Kasvain's Modded vBIOSes for AMD videocards ::This thread is mainly for discussion about my releases. Please post your vBIOSes to some another thread if they are not left for modding
I have done so called memory strap mods for some AMD videocard vBIOSes lately just for fun. I'll keep a list of all modded vBIOSes in the first post.
The major thing in the modification in these is a faster video memory achieved by using modded memory straps and sometimes lowered voltages to achieve better effiency.
I'm using all the modded vBIOSes myself I've posted in here and will update to newer if doing changes to ones already posted.
Every vBIOS will have some information about it and what card it's made for and so on. I don't take any kind of responsibility of any damages or loss made by my modifications. Use with own risk. Always backup your original ROM first, I recommend strongly using AtiFlash or AtiWinFlash for backing up the original vBIOS and for writing the new vBIOS.

This is a OC model vBIOS. The OC model does have a 1330MHz core instead of 1286MHz. If you card can handle a little higher GPU clock speed, feel free to use it.
