Flashing X800XL to X850XT !!!

[AllBrain]

Hello,

I just thought I would tell the world and his wife about the success of the brilliant X800XL by Powercolor that I bought from overclockers. I think the problem with overclocking was always bios written limitations and so flashed the X800 XL with the X850 XT (not PE) bios and not only has it worked, but also is rock stable and runs alot better than Powercolor ever intended.

I used ATIFLASH and got the bios from a saved file from a mate who actually has a bonified X800 XT.

Try it guys it really works, cracking cards those XL's £230 was a bargain.

Overclocked core is sitting pretty at 535 and memory at a slightly overclocked 1180.

Can this be true?

[mcnbns]

Sounds a little far-fetched, TBH. He flashes his 90nm card to a 130nm BIOS (not sure if that's possible), and then miraculously he gets another 100MHz out of the core and RAM?

[alexio]

Maybe in some X800XL's (the ones with the power connector) they use X850 XT cores that didn't pass th test but did have 16 working pipes.

In general it just seems impossible to me. If the X800XL is so much cheaper to build but still can run at such speed they'd have just cancelled the R480 before production and made dual core R430 cards and very cheap X800 XT's or something like that.

[zA.Gosu]

Well, a bit more core voltage?

[mcnbns]

They're built on completely different architecture! It's like changing the BIOS in your motherboard to make your Winchester an FX-55. It doesn't work like that.

[GazC]

It's be nice to see one of the powercolor X800XL vivos with the heatsink off. Even so, with 2ns ram it is still going to be crippled for overclocking.

Only worth considering if you have actually bought one already, imo.

[Jamo]

i agree with mcnbns, that it couldnt be done, getting the core from 400 to 535 is just taking it a little too far if you ask me, i cant see 0.1v vgpu giving those sort of miraculous results

[AllBrain]

This does sound a little too far fetched. But just think if it did work.

My post in charlie's thread about it

I know that the limits of X800XL in oc are low voltage and production process @ 0.11 infact it's hard to reach 450/550 with dissy stock and default voltage. And these are hardware limits not software/bios limitations... true?

Anyway my X800XL card has power connector and 1.6 ns chips ... uhm ... maybe ...

[XiN]

I've taken my 3D Club X800XL ViVo (with power connector and 1.6 ns chips) bios, ATI X850XT reference board bios and Sapphire X850XT ViVo bios to compare:



X800XL has R430, X850XT R480 but for the rest they are identical .... but I don't think flashing could be possible ...

[AllBrain]

Is the top right one the Sapphire? Looks a lot like the Club 3D bios...

[XiN]

Is the top right one the Sapphire? Looks a lot like the Club 3D bios...

Yes, top right one is Sapphire X850XT

... mine and sapphire have the same memory chips and they are both VIVO ... I haven't find a 3D Club X850XT bios to compare ...

anyway the problem is gpu: they have different names (R430 / R480) and they would be quite different for architecture ...

How can I see voltage of 3D CLub/ Sapphire?

[caater]

They're built on completely different architecture! It's like changing the BIOS in your motherboard to make your Winchester an FX-55. It doesn't work like that.

actually, it could be done..
think the ati pcb as a motherboard and gpu as a.. cpu.
they are using the same pcb for saving costs.
also 800xl and 850xt are basically the same, only diff is 850 being 0.13 lowk and 800xl 0.11.. also there is no need for different bios for fx-55 and winchester. mostly

so that leaves bios only ram-dependent.. and there's plenty of bioses floating around.

i think it's worth a try. but better have spare pci video for emergency

[don_vercetti]

i'm sure it is possible. Architecture size really doesn't effect the BIOS at all. The only real differences that the BIOS can affect are vgpu and vmem voltage (not sure if they are BIOS alterable on ati though) clock speeds and memory timing. I'm pretty sure in charlies mod he raised the Vgpu to 1.55 (i.e. stock x850xt) and got it up to about 530 or so. I think this mod is perfectly possible, and if i had one, i would try it.

um no, stock voltage of x850xtpe is ~1.4v, mine was 1.42v

[don_vercetti]

i thought you weren't going to oc it??

anyway charlie got his to similar, and it's not bad considering the new core is it.

Sorry about the error in x850xt voltage btw. I'm more of an NV guy at the mo.

[Magnj]

how are you guys doing volt mods, and are you gainging signifacant OCage as compared to stock voltages?

More like he wernt going to vmod it, ahhaha looks like that plan went out the window fast!!!!

Am waiting patiently to see where this thread goes, will be getting one of these as soon as it show sup at my fav store (better be soon stella!!!!).

mong

[sinsinking]

What's the deal..
both are running 16 pixel pipe. 6 vertex ...
if the 11nm is under clock like 100 mhz.. the card will be sooooo cold. But it's warm but not cold. We can't overclock from 400-500 without watercool or phase change.
Looking for LN2/phase change on 550+ clock :P

[AllBrain]

Here is another flashed X800XL that works just fine...

[Funny_S]

looks like it's really possible according to this thread. My X800XL will ship to me on fryday. Will try it myself and post a review-guide of the flashing.

[Gokou]

Still dont get it.... X800XT speed is 500+, havent seen anyones core being able to do that, soooooooo really need an X800XT bios with default XL clocks and go from there?

also would like a compare url from 3dmark.... not a picture, a link.

[_Eduard_]

Just a quick question: does the x800xl by default have 16 pipes or 12?

"16"

clocks are the ONLY difference!
