5970 linux voltage tool?

Just got my 5970 yesterday.  It wasn't detected by catalyst 9.11, but it is with catalyst 9.12 which is out today!  Performance numbers are right about where they should be compared to my 5770 ... that is 2*725/850 per GPU.  But I understand it should overclock easily to 850 by volting up to the 5870.  Is there a way to do this for linux?  At the very least, can one volt-up in windows and have it preserved when booting linux (haven't tried it because I don't have windows installed)?

WARNING DANGEROUS you can damage your card and varanty is void

you simply download BIOS of card. GPU-Z can do the job. (this is safe)

download RBEand edit voltage frequenci and fan rmp.

flash modified BIOS onto card with ATIflash.

everthing you must done in windows. before flash you should overclock card with RivaTuner or ATItool to measure you maximumu clock when it is stable. then modife BIOS with new values. then will card run with new frequencies and voltage under linux too.

OT: emuller did you brake 4 GPU in system barrier?

You may try ADL_SDK provided by AMD. And I have used it successfully on 4870x2.

Finally got around to trying out ADL.  AFAICT, ADL Overdrive5 API doesn't support voltages over 1050mV for the 5970.  A 5870 voltage would be like   1.1625v, no?

AFAIK this limits are in BIOS. you can edit BIOS and get higher limits.
