Hi
There appears to be quite a variation on Vcore between the various branded GTX580's.

I thought it might be interesting to set up a thread so that we can get an idea of the Vcore range and ultimately, how this may affect overclocking.

AFAIK, all current 580's are reference cards.

For the moment, please just state the following info in your post:-

Brand
default Vcore

Thanks:)
 
Gainward (vanilla version).
Default Vcore: 1.037v
Overclcoks to 870core with complete stability on default volts. Needs a bump to get any higher and 940 seems to be the stable maximun @ 1.1v. Can bench at 960 but crashes at vgpu max 1.137v.

I think NVidia recommends the vcore by batch. My two ASUS 460's had the same BIOS revision but different default vcores. Both ultimately overclocked to similar levels until Furmark popped one.

daft question
is voltage limited to bios or what afterburner allows ?

Afterburner will only allow what vgpu max is set to within BIOS. Currently, only ASUS 580's (or other cards flashed with ASUS BIOS) allow vgpu max to be set above 1.137v. Flashing is easy, but ultimately not worth it due to heat.
 
Every core has its own Vcore within a range, so every brand (barring something like gigabytes super overclock series) will have the same vcore variations.
