I can't speak for the 030 or 032 BIOS but the 028 BIOS solved my issues with the core clock jumping up and down, my powercolor EZ came shipped with 031 BIOS installed

It's not hard to flash a card even if it only has one switch position. SEt up boot disk with atiflash and rom to filed... boot...

Even in the dark just type atiflash -f -p 0 nameofbios.rom

Done.

Yup! That's what I think I might try doing with on own in the near future.
I really wonder what changed in there between 028 and 031 to bork it.

Anyways, I pointed it out to ere on the side of caution. If you can't afford a 200$ paperweight, be careful, But id that warranty is mostly just a piece of scrap paper anyway, have fun! And be careful.smile.gif

028 solved all my problems with gpu usage and clocks throttling thumb.gif

Both my crossfired Mysts have the 028 bios and I have not experienced issues. I've learned from hard experience if it ain't broke, don't fix it. Can't comment on the other bios releases but have not heard many complaints from 028 owners.

028 bios was the original bios when the card was released. I got one from Ncix at initial release.

Bummer I was looking forward to seeing how you got it mounted on the VRMs.


I have used that block on a MSI GTX 560 ti 448 card before and it worked out well. I have photos of it in my 2nd sig that is offset to the left.

Flashing your card with a different BIOS than that which it was shipped with will just about void your warranty, and there is the possibility that you may brick the card in the process.


I doubt updating the BIOS on a card to fix a problem that has been corrected by a new BIOS will void the warranty.

Do these cards come with 1 and 2 BIOS switch? If so it shouldn't be to hard to experiment with BIOS flashing with ATIflash.

My Sapphire card has a BIOS switch. 2 options.

That is good to know and having 2 BIOS switch positions is super handy to have when experimental BIOS flashing because with only 1 BIOS and a bad flash and the display is lost and it can be tricky to run ATIflash without a display image but it can be done but you have to know how to boot to ATIFLASH and type commands properly without having display in the dark/blindly.


Another option is to boot from a cpu that has integrate gpu for image out to monitor like a 2500k/3770k extra and do the flashing from there but then its a hassle to swap video cable around if you only have 1 monitor. With 2 monitors it is easier to do... But yeah 2 switch on BIOS is the way to go for experimental flashing with ATIflash.

Just did a "suicide run" on my 7870 MYST. 1350/1500 @ 1.3v(it really goes up to 1.32 in this case).



If someone could tell me how to properly get the results from an html to a picture, itd be appreciated. Thus far i have been print screening. 1254 on extreme though, thats only 100 shy of a gtx 680...unfortunately I can't duplicate the results mad.gif
Impressive from a 200$ card nonetheless.
