HD 2600XT 512MB (Palit) Voltmods

[albertwesker]

Hello,
I'm searching for a voltmod for my Palit/Xpertvision 2600XT 512MB. Is there any mod available?

thanks

i could find these voltage regulators on the card:

APW7065 and RT9199

[albertwesker]

these measure points seems to be unrealistic for Vgpu and Vmem. Which other points could i measure for getting Vgpu and Vmem voltages?

APW7065 I think this one control vgpu, solder 20Kohm multiturn trimer on pin 6 and gnd.

For vdd i think there is other IC. Wait for more answers/ideas or ask persivore/johnny (they rock).

thanks for the answer, icy.

here are some pictures from the card and the regulators on the PCB.

Don't touch RT9199!

BN-9D L0G - Vgpu-controller. Measure resistance from all legs of BN-9D L0G to ground and post here. I think pin 14 is feedback. You need to find smd-resistor that connected to pin 14 of BN-9D L0G and ground.

APW7065 - Vmem-controller. Solder 10K ohm VR between pin3 and pin6.

Measure Vgpu at "CP4" holes and Vmem at "CP1" holes.

I'm 100% sure.
