Well I probably don't remember that exact numbers, maybe it was 193W

But in furmark 1.9.0 when using the 'dynamic background' test for burn-in, it lists the watts, volts, amps live on screen

And using GPUZ 0.5.2 with my non-ref sapphire, I get loads of info, present, maxs, mins....

I just did a quick furmark of 970/1520 @1.3V, it artifacted for 1 sec, then ran alright, but it started to look like it was skipping...

So I set it to 965/1500 @1.3V and it didn`t artifact and ran smooth, I just let it run till the temp settled at 78C



So 117A*1.3V=152W, but I`m not going to try 1.4V again anytime soon.

And heres a crysis warhead stable with 970/1370 at 1.25V (before I knew what the VRAM could handle) with 87 Amp max during however long I played

is your card reference? my vreg temps or current doesn't show up in that version of gpu-z.

Yep, his card is non-ref which uses the TI DrMOS vrm units which is supported. The digital Volterra vrms are not supported. It's a love hate relationship with the volterras.
