Hi,
I have a problem...
I used ntimings with my Peak 6600 (non GT) card....
with this settings:
TIMING0 : 060b1003
TIMING1 : 05010407
TIMING2 : 00240306...
After reboot, during boot
I can't see the windows logo...
I can see only a blank screen...
I tried to flash firmware but, with different firmware, I have the same result...
I used also sparkle ultra firmware... before ntimings this worked....
Anyone have an Idea?
Best regards...
Antonio

P.S. excuse my little english....

i got a chaintech 256mb 6600 agp.

i shaded the R87 resistor and the result is the same. still a max of 452mhz on the core. so i used the eraser to clean it off falowed by 90% alch.

so the pencil i used im not shure what number it was should be a number 2 but it was a cheap one with no number on it. should i use a good number 2 pencil? how dark should i shade it?

ok stock R87 was 500ohm i penciled it to 460ohm and at first i could get to 500mhz but it would haing i would restart and it wouldent let me go to 500mhz only 452mhz on the core and would run it fine. anyone know whats wrong?

why don't you try with the original firmware?
It is possible that the firmware is OK, but there is no image on the screen becouse you have "burned" some of the video RAM chips.

Hmm... pretty old topic .
But yes, I have a 6600 to voltmod - maybe someone can help?
I've been looking for VMod for some time but no luck - I doesn't find any PCB similar to that used in my card .

It's Leadtek PX6600 TD, non-GT, 256MB, PCI-E version.

I have a pencil and a multimeter (and I'm noob in VGA modding , only VDimm on P5B-Dlx and VDroop on Commando already {both by pencil, succesful}). Any suggestions?
