Get your X1950Pro modded BIOS here

Kursah · Mar 21, 2007

It'll be worth the wait when Ketxxx pulls out the new bios. I think it'll open new OC levels for the x1950 pro. I'm very excited to try it and see the results!

Ketxxx · Mar 21, 2007

Ok the first version of my ultimate tweaked BIOS is just about complete. Heres a full list of what its had done to it;

- Memory timing tweaks
- Memory refresh rate tweak
- Fan speed 100%
- Default VGPU 621MHz
- Default memory 1.4GHz
- Attempt at improving overclocked stability
- Improved memory overclocking

Notes: This BIOS is strongly recommended to be tried with Palit, Xpertvision, and Gecube cards which are having trouble OCing and stability problems. It should be fine for most cards, feedback of how the BIOS performs on other cards is welcome.

Compatibility Notes:

- Compatible with Samsung memory, other memorys untested.
- VIVO is not supported in this BIOS
- Based on a PCI-E 512MB 1950Pro BIOS

While testing it was noted that this BIOS improved VGPU OCs. Previously ATItool would lock at 648MHz instantly, now ATItool will continue scanning for max VGPU frequency to 661MHz on the weakest X1950Pro the BIOS has been tested with. ATItool has been set to scan for 20 seconds before increasing clock frequency, so this was not a one-time fluke, and has consistently passed its previous limit of 648MHz.

I hope the BIOS brings as much success in the "real world" as it has done in testing :cool:

It would be great if people can give me feedback on new VGPU \ memory OCs so I can perhaps make a few adjustments for speed and stability.

Nice. Will have to give it a try (moded to 256 of corse) in a bit.

BTW Are timings tightened or relaxed.

Ketxxx · Mar 21, 2007

Their a combination of both, they should allow for a maximum performance to OC ratio. I opted for this method as the card is not bandwidth limited by any means, it seemed pointless completely relaxing timings on a card with no bandwidth limitation. This BIOS combined with a VGPU vmod should see some insane performance too. Quite possible the 1950Pro could crack 14k in 05 with this BIOS and a VGPU vmod.

ed- I already have a v1.2 thats almost complete

it just has a little testing to be done as I want to try and improve stability a little more.

josh64fx · Mar 21, 2007

They work fine with ATI X1950pro 256mb PCI-E??

Whats the highest you guys have it?

Formula350 · Mar 21, 2007

Yea, its a simple edit to make it 256.

And how do you do the VMod?

Ketxxx · Mar 21, 2007

Vmod depends on your card. Its trickier for me cos I have a non reference PCB, thats not all bad tho as I dont have to deal with that damn vitec\pulse chip, my card stays nice an cool.

josh64fx · Mar 21, 2007

simple edit for the 256mb?? How do I do that?

I thought this one was ready..

X1950PRO 256MB v1.1.zip << Does this work fine with the ATI X1950pro 256mb?

Formula350 · Mar 21, 2007

Yes, simple

Hope you don't mind Ket, here's yours as 256mb nothing else touched.

Ket: What all else is done that would allow for higher core? The few mem timings I saw looked stock to me. The Voltage just said "Default" heh but if I wanted I'm sure I could look, is itjust 1.45?

Ketxxx · Mar 21, 2007

I havent done anything like voltages.. yet anyway. I took a BIOS that was specific to Samsung memory for maximum compatibility and tweaked the crap out of it to improve stability and overclocking. Timings while looking stock have actually had suttle changes and rest on a platue between 1.1ns and 1.2ns timings. As I said, a balance between performance and maximum OC

unsmart · Mar 21, 2007

A core increase without a VGPU increase :wtf:

What did you find in the bios a speed lock or just sloppy settings like the mem?
I figured mine was PWM IC related, I really hope I'm wrong

I would love to get my core over 621 stable.
My hats off to you on the timings :respect:

I messed with them last night and thats some real tedious sh*t, I could only handle about and hour of it. The tighter times did raise my ATT bench by about 140 at stock

elfizs · Mar 21, 2007

Cant flash

I'd tried to flash using flashrom 2.40 cmd line but not succeed

A:\>flashrom -f -p 0 modv1.rom

Adapter 0 not found

A:\>flashrom -i

ATi video adapter not found

I am using ABIT AB9 QUADGT. Please help with the solution. :respect:

skandal · Mar 21, 2007

Use atiflash, altough it didn't worked with my X1950GT it should work with the pro.

Formula350 · Mar 21, 2007

He hasnt gotten a GT BIOS dump yet, so I wouldn't be tryin to flash a GT with a Pro one yet.

On that note, dump and UL your BIOS, Skandal.

Elfizs. You using DOS, or command prompt?

I couldn't upload my bios.... none of the tools detected my graphic card. The pro bios shouldo work perfectly in the GT.

Command prompt after restarting windows. I'll try Atiflash later on. Ehm, is there need to dump my bios too?

elfizs · Mar 21, 2007

OK. now i had already flashed the bios using atiflash. But somehow the result is not going well with my xpertvision. Kentxxx, is there any specific driver that u used for tweaking the bios? Is it becoz of pcb revision? I tried 3dmark and it quickly showed artifact and then blue screen. I tried using NGO 1.7.2, catalyst 7.1 and 7.2 and the result was the same.

Is your card using samsung memory? If its using something like hynix memory the BIOS deffinately wont work

Flashrom doesnt work with X1950 cards, you need to use atiflash 3.25

Sloppy settings, which in turn sort of act like a clock lock as the settings arent as stable as they could be.

Marioace · Mar 21, 2007

any one who owns an Sapphire X1950Pro Ultimate could submitt their VGA BIOS please?

Dumah Brazorf · Mar 21, 2007

Atiflash worked with my Peak vga using -sst option.
I've flashed a bios with different fan settings, nothing changed. Useless.

Why dont you dump your bios and upload it here if that is what you have? Have you not made a backup of it?

cause i think the BIOS is wrong, because my VGA is not detected by the drivers, but it shows image

Sounds like a system \ driver level problem.
