Gained 50mhz core and shader in games I play.
Not shabby for a fast mod.

Its however clear it needs a hard modd, the card got potential.

To anyone who thinks their clocks are rock-stable. Try running the crysis demo gpu benchmark a couple of times. I have a slight feeling that some of you will be a bit dissapointing...with the red textures appearing all across the screen suddenly :P. Even tho' my shader clock was ati-tool hairball stable, it was nowhere near stable with the crysis gpu benchmark. My whole screen froze and was filled with small red squares at some point in the loop.

So by all means, if you want to REALLY check your clocks, go grab the crysis demo and run the gpu benchmark.

I can actually run Crysys GPU test at higher speeds than atitool stable so as usual, every system is different.

agreed. All my other games were running fine at 756/1890, but Crysis locks up with 756 core and 1890 gives me artifacts, tile squares pop up randomly.

That's nothing...

This is what I use for my Crysis test... http://aycu07.webshots.com/image/329...4552298_rs.jpg

I shoot a few nukes off for good measure as well. 713/1728/999(run at 948) stable

3dmark06 able to run at 750core. Pushed me over 12k which was nice.
However, once you start add some draw, and I test games, LOTRO using dx10 i get stable at 690core, which is a 50mhz increase since the bios mod.
It runs cool under water.
A hard modd is needed since the card got some headroom built in.
But stable 2 days testing 690core.
Gonna try 695 next to see if that works.

Same here. I can run AT artifact free at 705/1728/1000 but will lock up in Crysis anything above 690/1674/1000.

Crysis is like P95 for GPU :ROTF:

Just bought a new floppy drive and I'm going to try the bios mod to get +.05 Vcore and see I it gives me better results.

Then my Computer is all wacky as I can play and bench Crysis at higher (not a lot mind you) speeds.
I am going to find my floppy and do the mod as well. :)

Indeed crysis is the main tester to the GPU. Surely I'm enjoying my 720/1782/950 stable easy, would right the memory at 999 but worried about that memory issue going around, which really it sounds like a heat problem more than anything. But playing it safe, rather then sorry.

Gotta give that bios thing ago again, just gotta give it a whirl with a little more time this time to see why I can't backup my existing bios. I'd love more speed :)

Before ni couldnt get my XFX card stable @ 738 / 1782 / 1044

And now? :up:

Its now 771mhz Core and 1890mhz Shader stable.

Havent tried Crysis yet but it runs benchmark in 756 / 1836 / 1044

What process are you using to back up the BIOS? I just open up Nibitor 3.5a, and go to Tools-->Read BIOS-->Select Device, and then select the gfx card. Then I go to File-->Save BIOS.

Somehow I can't read or backup BIOS with nibitor. I have to use nvflash to back it up.

Is there any way to create a nvflash capable boot disc? I did one with Nero and added the nvflash file but couldnt find it when I rebooted....
PS Never mind I will just drop everything on a C:// folder and go there using command prompt. :-)

There are 2 files that need to be added to the boot disc. They are cwsdpmi.exe and nvflash.exe. I have no experience creating a bootable CD for this purpose, though, so I'm not sure if there is something else you need to do.

Follow the instructions given in the links below, you don't need Nero, you just need to format the floppy with windows and check "create a MS-DOS boot disk":

1. Create MS-DOS boot disk
2. Copy on it latest nVFlash.exe and cwsdpmi.exe that comes with it
3. Boot into DOS and with "a:\nvflash.exe -b a:\backup.rom" backup existing BIOS
4. Edit autoexec.bat on MS DOS floppy so that it has only "a:\nvflash.exe -4 -5 -6 -a -y a:\backup.rom" (commands taken from here.) ONLY USE THIS DISK FOR RECOVERY! It will flash your card at each boot!

Actually I wanted to avoid finding a floppy and a disc as I dont use floppy in my computer. :)

Laugh all you want, but the floppy still comes in handy every now and then.

Struggling to get a proper CD made, or getting USB Flash Drive to work is a PITA!

Hey folks, thanks for answering my mail! I am almost ready to go through the procedure. When I format and create a ms-dos bootable floppy, it adds like 8 files to the floppy disk. I suppose these need to say in there while I do the flashing?

The nero boot cd works and I get to command prompt so all I need to do is go to the C folder where I put the files and flash right?

Yes. Just leave those files alone, and add the 2 nvfalsh (xxx.exe) files, and your 2 BIOS (xxx.rom) files.

Reboot to the floppy drive and go!

In theory, yes, that should work. Just make sure your nvflash files (2 xxx.exe files) and BIOS files (xxx.rom) are in the same folder and navigate to that subdirectory. I've never tried it, though.

Early flash report by me: The flash succeeded!!! Thank goodness, the thing did not burn up or blast me in the face with fire. The gpu temperature has raised by 3 celcius. This is an indication of success!

I've just had thought to add my 3 cents.

So I've modified bios with NiBiTor v3.5a. All volts set to 1.1 exempt for 3d.

I can now confirm that this mod is working 100%.
Just before the mod I've again tested max stable OC just to confirm my previous results. The ambient temperature before and after the test remained the same.

Standard bios - gpu/shaders - 729/1674 anything above that would give me errors in ATITool

Oc bios - gpu/shaders - 738/1728 anything above that gives me errors in ATITool

Just wanted to say thanks for the author of this !

YEAH Babe, every little help ( especially in Crysis )
