Flashing the X800 Pro, among other things...

[Kunaak]

well tonight I spent the last 5 hours playing around with various bioses for the X800 XT and Pro, to see if anything interesting would happen.

using this flash utility, in the link I could flash to various bioses and try out things.

flashing from the X800 pro bios to the XT bios did nothing for me, Kinda...

see it didn't up any pipelines or anything.
but it did make my memory ALOT more overclockable, from 540 max to 575 stable and easy with the X800XT bios. (default for the X800 XT bios)
so it didn't make it open the last 4 pipelines, but it did allow me to OC the Mem alot better, but the core was the same (570 for me)

so it wasn't a bad flash at all.

heres the exact way I did it.

download the flashrom235, extract it to a bootdisk, put the bios you want on there, and reboot.

at the A:\ promt, put in...

flashrom -f -p 0 "BIOS NAME HERE" .BIN.

for the BIOS NAME HERE, I renamed the BIOSes according to the card they came from, so it was a X800XT.Bin file for me.
so my flash command was.

A:\FLASHROM -F -P 0 X800PRO.BIN

thats all if you wanna try to mod the card yourself to X800XT speeds = minus the last 4 pipelines still.

flashing it was worth a shot, and trying a few different, bioses I got a more overclockable card.
except I kinda screwed up.

I left Powerstrip on and it must have locked in the speeds I shutdown at cause now my card is back to a X800 Pro Bios, but the default speeds are now 525/520.
it's not bad cause thats 100% stable.
but I would like the option to edit my default speeds back to normal incase I have problems later on.

so I need a ATI Bios Editor.
anyone know of one that works with the X800 series??

cause none I tried yet do.

heres some bioses to those feeling adventurous.

Supossedly, if you want 16 pipelines you have to close a bridge.

You connect the bridge when the card is a Pro.

Next you flash the bios to XT.

This is supossed to work, I'll be trying it this afternoon.

I'm guessing it didn't. Haven't heard a word from him all day.

from what i understand you have to connect the two dots AND the fine cut of the line connecting those dots. to see that line and connect all the three points you need to carefully scrape off the protective layer first. its the same clear epoxy layer we have on intels chipsets/cpus and amds cpus.

so actually you have to short the two dots with the second copper layer underneath the two dots through the laser cut, and not connect the two dots like we all thougt.

I was thinking along those lines too after reading about this topic in many of the boards. Something peculiar though about this process....

Why have the people with Sapphire boards been able to mod this card sucessfully and everyone with a BBA card not? I don't think that the Sapphire owners connected the two points AND the trace underneath as a coincidence and the owners of the BBA not.

Could the Sapphire cores be different? I don't think so.

I hope someone with driver/BIOS knowledge will figure out how to do this on BBA cards as for the moment I see that as the only "possible" solution. We'll just have to wait and see.

Thanks to Kunaak, it works, : )

Now can bench with 3dmark at 585MHz (RAM) without any Artifacts, before it was 567MHz (RAM), any higher, it hangs!!!!

And now my X800pro can run 3dmark at max 605MHz (RAM) with some triangles, it seems that it can still be higher.

But the X800XT's BIOS is with VIVO???
