what is fan optimized?

And have you tried the mod bios with 1,4125? I shall work, the other for 580pro almost fried my card

Last time I tried CCC, it didn't apply the clocks that I asked it to. Change in CCC indicated no change in ATITool, even with the ativexx2 2d/3d clock switcher disabled.
 
im keeping a good watch on this threat, i want to see the first one that gets the unlocked pipelines thingy right :).

Try it out, if your fans act funny, Ill change back the fan pwm.

This is made from Migou's Sapphire BIOS, it should work for yours.

I would say the first person who gets it right would probably be laydback. He's fiddling around with the BIOS hex codes more than I am. Besides, I don't know much about HEX and ASCII.
 
I need someone who's willing to test it for me, someone who knows the bios recovery process. And their card's BIOS.

thats the max for me to.. but when i go higher then 620 my card crashes. and remember im on the stock cooler aswell..

my card is a Sapphire X1900GT....
 
tofu, when you modded the Sapphire BIOS. Did you try to also change the deviceID to match the pro?

NO, deviceID remains as 724B
 
Hrmm, that might be worth a try. I opened up the BIOS you just modded the vgpu on , and its already set to "18" , maybe changing the deviceID to match the pro bios triggers something. It's worth a try for whoever is willing to risk it.

CCC overdrive thingy works fine for me. i use ATI TRAY TOOLS to monitor temp and clock speeds.. everytime i go in to 3d mode the clock raises and lowers.. but as soon as i use atitool and disable the overdrive triggering system it just stays at the stock clocks.. try not to dissable the switcher and you should see a change..

and sorry about you card.. best of luck to get it to work yet again

You need increase GPU voltage. Default 3D voltage is 1.25V, increase to 1.4-1.5V and then you see...

ur cpu is bottleneking ur card i think because i got 10,147 on 3d mark 05

No, its not... i check serveral tests X1900GT and its all 8500 - 8800 points... (CPU AMD X2 4800+)
I run 3Dmark05 again and result is 8950 points, its maximum.... (on 12 pipes)
 
tofu have you tryed the modded vgpu bios for sapphire out.. Are there any problems with movies with higher vgpu
 
i can oc to 650/720 on stock volts on water

try if this build of atitool works on the x1900 gt

Nice, W1zzard!!! If only I still had my X1900GT! :banghead: :banghead: :banghead:

Works perfectly for me.. Fan controle. volt controle.. still no go for the mem timings. but i dont know if thats even possible.

From all that I've tried (x1300pro, x1300pro agp, x1600pro agp, x1600xt, x1800xl, x1900gt) mem timings cannot be changed.
 
This is for all those inquiring minds out there: my x1900gt (unlockable)
