OK I give up WHY WONT IT BE A PE!!??

INSTG8R · Jun 23, 2005, 06:37 PM

Okay so I thought I had this PE thing licked but NO NO its still unstable when flashed to PE BUT!! if I leave it as an XT and put it at PE speeds it runs artifact free for hours.
As soon as I flash it BOOM! artifacts I tracked thru a few BIOS's(very little changes in them really)I even tryed using the Modified Flashrom and put a blank BIOS(the one used for X800s to open the pipes) thru it once. I also discovered while in there the ROM is locked(wondering if that may have something to do with it?
I did the cheat way of changing my BIOS ID and clocks now granted its stable and shows up as a PE but the Cat's know its not cuz if I flip to the OD screen its set to XT clocks in there(no I dont use OD but its good reference)
FOR THE LOVE OF RADEON WHY!!???

if it works with out the Flashed at PE speeds then dont flash it. all a PE is a overclocked XT. so flashing it to PE will not make it any better then what you got it overclocked at.

True Claymore but there shouldnt be any reason it wont take a PE flash thats the part thats frustrating me

There can be several reasons why this happens but a BIOS swap does not guarantee 100% compatibility. What happens when you flash then downclock? Do you still get artifacts?

***Zardon*** · Jun 24, 2005, 05:48 AM

its possible the PE bios has different ram timings.

wow zardon, NICE new sig and avatar!

Its also possible that BIOS has a different voltage setting or a BIOS for a different fan controller/temperature monitor.

Just take your BIOS you have now, edit it to have the PE speeds you want, then flash it with that to guarantee compatibility

Yes Hex that is a possiblity I have considered and flashing it with Powercolors own PE Bios makes no difference in fact I edited the device IDs and clocks of my original BIOS tho it showed up as PE the Cats still knew it was an XT ans the Overdrive clocks were 500/500.
Zardon I always check BIOS's before flash and the Mem timings are Identical.
daedel yes IF I flash it to PE and downclock it to say 520/540 the artifacts stop tho I can crank the crap out of it with the XT BIOS 540/573 is where I gave up. this Issue has something to do with the Memory tho I cannot for the life of me figure out what..

H3X4D3C1M4L · Jun 25, 2005, 03:06 PM

Well you'd do better off just to overclock it to 540/573 rather than suffer for just a name to show up and for overdrive to be there.

No point in using overdrive once you've overclocked that high as you've already voided the warranty

take a close look at the bios files fine setting by useing rabit 1.7 (Radeon BIOS Tuner)

I don't even think it matters. For a few letters to change that you see once in a while, I don't think it is.

Just flash it with its own BIOS, using RaBit to edit the clock values to reflect the max OC

Thats a verry bad idea O/cing via the bios can land you in a world of hurt. He need only chage the timeing of the PE bios to match to orgional bios and see if it fixes the corruption issue..

How is it a bad idea?

Its the same thing if he runs his card @ those speeds, its just now his BIOS defaults to his best OC speeds.

Its better than screwing around with RAM timings which causes irreversable damage really easily
