Radeon 6950/70 oc'ing voltage weirdness

[Deaks2]

For over a year my 6950 has been soft modded into a 6970. I have been investigating the vcore, because even though the BIOS was modded to 1.175v (like a 6970) some monitoring tools still show 1.1v, while GPU-Z shows 1.175v.

Apart from running a multi-meter on the card, how do I determine if my card is getting the juice it needs? Based on the fact that Kombuster/GPU Shark is showing that my card is a 6950 with 1408 shaders @ 1.1 vCore, while GPU-Z states 1536 shaders @ 1.175 vCore, perhaps the first tool is simply showing what it thinks a 6950 should look like?

I have attached a screenshot and a dump of my video BIOS here: https://dl.dropbox.com/u/22601891/Cayman.rom

Any ideas?

Download HWinfo64 and see what it tells you. It is one of the truly reliable programs that will relay the correct information.

Just to add some info.
Kombuster has never properly read my cards voltage either, so the issue isn't isolated to your setup, its a Kombuster issue.
While GPU-Z has always been accurate for showing proper shaders, speeds and voltages in 2d and 3d modes as does HWINFO64 as mentioned above, so trust those and ignore Kombuster.
