Need help with 7950GX2 volt mod

[mdzcpa]

Well, I'm stumped.

I performed the Vgpu volt mod as described below, connecting the two pads for the 1.5v mod. I used a conductive pen. It simply didn't work :confused:

Here is what I followed:

I performed the simpe 1.5v connection.

Before the mod I measured 1.25v, and I get the same after the mod.

I've done lots of bridge closings with conductive grease and conductive pens in the past. I know I have two clean connections. I also show 1.25v on both cards, so I would have had to botch 2 connections which isn't as likely.

The card is the XFX 7950 GX2. Any tips would be appreciated.

noob question but did you do it to both cards?

[mdzcpa]

Yep, both cards modded.

Both show no change in vgpu.

Here's crappy pic of the top card connection. The bottom card is the same. I used a brand new conductive pen to connect the pads.

(The pic is bad as the card is still installed):

Re-did both bridges again with conductive grease. Still no joy :(

Maybe try soldering? No idea really, Shamino might explain :)

What do connection points say measuring them with DMM? Before mods they should be like 1.14V and 0.02V

[mdzcpa]

Before the mod, the vgpu point measures 1.25v. After the mod....the same 1.25v.

Well, I've tried both conductive grease and conductive pen. Both have worked great with mobo traces and old AMD XP bridge connections. Perhaps solder is the way to go. :confused:

I meant these 2 points, marked with red :)

What do they read before/after the mod? The one closer to 0520 should read around 1.14V before mod

Okay....I got ya. Hmm.....good question. It'll take me some time to remove the bad connection material and try to measure the V while the card is installed in the case. This won't be easy, but I'll try to get the measurements.
