its a very good card too. will beat any g2 card except for the g2ultra! cant help you though...sorry :D
i think any pre g3 cards took the voltage for their memory directly from the agp slot, so its tricky to raise that voltage.

i love the GF1 DDR,
i have one now too, fixed from death from an friend, modded the coolant, and modded to quadro....
got 4339 3dmarks atm, but anyone know whats the fastest detonator for this card , and im also interested in getting the vmod/ for core and mem
mem could reach 343 but only 3dmark staBLE on 338 or so. ;(
PLEASE help us out here! :p

I'm currently first on the ORB for Geforce DDR cards.. but as i ran it as a Quadro, it can't submitted.

On you VGA, is there a voltage regulator IC Unisem US 1150 ? this chip has 5 pins.
If yes, then on pin 1 (Vsense) and pin 2 (adjust) connect 120 ohm resistor. To measure, use voltmeter on pin 3 (Vout) to ground. It should be 2.5V ( normal / default 2.05V for GPU ).
For memory?? too bad..... the voltage power comes directly from 3.3V lines. You need to increase 3.3V lines from PSU.

:confused: I didn't find that component, do you have a pic ?
My 3.3v has already been increased to 3.55

does your card got this chip:
Linfinity LX8368-00CCD
?
edit: i mean: LX8386-00CDD , sorry.

I think I have it, but i'm not sure : Linfinity LX8386-00CDD (and not 8368-00CCD)

sorry my fault.
of course i mean the LX8386-...... :
http://www.microsemi.com/datasheets/LX8386.pdf
i think it produce ~3.3volts from the 5volt line from psu, but is it the ram or the gpu who needs this 3.3v?
i will try to increase this 3.3v outgoing from this chip to 3.6-3.8v and see what happens.
actually ive got artifacts when i running the ram over 180mhz (360ddr) .
btw: #1 in gf1-ddr class in 03 with whql drivers and default bench. juicy 300 points :D
