ATI X1900gt Unlock Bios Found ???

[xforce]

Someone in techpowerup found a way to unlock the 16 pipelines.

Original thread

Update:

DO NOT USE THE BIOS YOU PREVIOUSLY DOWNLOADED FROM THIS FORUM, IT MAY NOT WORK ON YOUR CARD AS THERE ARE TWO REVISIONS TO THE R580 CORE

Long story short, there are basically two revisions of the ATI R580 core. One is referred by the engineers as the R580"XL" and the other one is known as R580"PRO". Apparently, if you swap the BIOS on the cards, IT WILL NOT WORK. I just flashed Migou's R580"XL" version BIOS into my card, which is based on the R580"PRO" core, it fked up, and ATIFlash no longer recognizes the card.

If you still want to pursue the 16pp unlock, please post your dumped BIOS and I will mod it for you. If you want to mod it yourself see the X1800GTO @ X1800XT mod thread. Works upon the same principle.

Before sending me the BIOSes, open the BIOS with Rabit and see if the Description says R580 "XL", if it does, don't bother. Make sure before sending me the BIOSes that the description says R580 "PRO" as shown below:



To sum it up, here are the requirements:

i)Make a backup of your card's bios. The bios description must reflect as "R580 Pro" when opened using RaBIT editor
ii)Rams must be Samsung 1.4ns
iii)Use ATIflash dos proggie to flash the bios

Someone test this one please !!!

Definetly need verification before I buy a x1900gt before price spikage.

Heck, even if it doesn't work, an X1900GT still is better bang/buck than anything else out there.

I decided to just ask w1zzard real quick before I headed off to bed whether or not he thought it was legit. He replied "should work fine", but wasn't sure if it would at all be brand dependent.

What would the GT turn in to? XTX?

An XT.

not x1800xt. i picked my 512 x1800xt at newegg open box for 240 a couple of weeks ago.


we need verification of this working though. anyone want to test it?

[Timmay]

I thought most XT's had 1.1Ns Ram not 1.4??

[Shadowmage]

Tested it, and failed. Still 12 pipes, and my card acted funny. Flashed back with no dmg

BTW X1900GT 256MB is still faster than X1800XT 512MB in most cases, when both are OCed.

sorry your card didnt work

that's simply not true

[Shadowmage]

The X1900GT OCs more than the X1800XT in most cases, which is why I say that...

I'm pushing mine up past 720mhz GPU (still got a lot more voltage headroom to go, only using 1.375v) and 863mhz RAM (1726mhz )

[dimcar]

Sapphire and GeCube DO NOT UNLOCK!

[Shadowmage]

Mine is BBA and it didn't work as well.

The pipeline count was still 12.

There should be a better method for unlocking...

[keiths]

It's better bang for the buck if you don't count your electric bill. ATI uses way more electricity.

[Shadowmage]

Ha, once you OC and vmod, any card will have super-high power consumption. What you said is only true at stock.

[laydback]

Opinions please...

x1900GT or x1900AIW?

[K404]

Arent the pipes laser cut on the GT, so it`ll take a pencil or similar mod to stand a chance of getting all the goodness from the GT? I reckon ATI would be...unwilling? to repeat the success of the X800GTo seeing as the X1900 is not at the end of its life?

[Shadowmage]

Opinions please...

x1900GT or x1900AIW?

The AIW has the 4 pipes unlocked, but it costs like $300. Your choice.

[laydback]

I already have an AIW, but was considering trading it for a GT cause it clocks better? But the AIW has more pipes and vertex shaders.

[Shadowmage]

nvm

[hot_fifty]

sapphire cards have Xl core and not pro.. i have sapphire X1900GT.. so dont unlock sapphire cards

Keep the AIW, unless someone finds a way to unlock the newer GTs.

[ganescha]

i had no luck on unlocking my BBA X1900GT, but i have only tryed Winflash, cant get atiflahs in dos to work. I use 3.09 but i stil get "adapter not found" any ideas on what version i should use to fix that?
what drivers do you use with your X1900 card? is 6.2 faster then 6.6?

[mitsirfishi]

i hear that the older r580 core on the his ones are the most sucessful but only a few have been unlocked but the newer x1900gt's have an r575/r570 core which is slower and clocked at 513 but they have speeded up the memory to 1312 so suppose the slow down of the core compensates for the memory a great card for its money i would take 1 over a 7900gt
