Hey everyone...I recently got my hands on a Voodoo3 2000 SGRAM that, to my surprise, has the Samsung 5ns RAM chips. The card runs great at 166mhz and stable at 184mhz, but with artifacts. I was wondering if anybody has a Voodoo3 3000 SGRAM (PCI) on hand that could tell me what are the values of the resistors right next to the voltage regulator (R10 and R11). I'm thinking about doing a voltmod just to bump the voltage up a bit and get rid of the artifacting. Thanks!

Here's a pic....you can also see the resistors right next to it....I'm wanting to know what are the values of those resistors in the 3000 card.

this is weak 3A VREG.
no way it can push 3dfx chip to 184mhz.

Voodoo 3000 has 7A VREG.
