Sapphire 7950, 640 khash @ 200 watts

[Kinetic915]

Hello all,

I keep seeing posters reporting their 7950s can hash at 640 @ 200 watts. 

I currently have no idea how this is possible.  I can hash at 550 per card @ 585 power draw, which seems extremely high?  Any trick to this?

1.019 v, 10 powertune, 925 core, 1250 clock ~ 585 total

Have one hard drive, a cheap celeron cpu, wifi card and no other peripherals.

Any help always appreciated!

Thanks!

Hi

Where are you looking at the measure? Just the GPU or the whole PC? Check the GPU consumption with GPU-Z by Powertechup
I have a 7870, mining at 1200 clock, cgminer, poclbm kernel, and hashing at 450MH/s with 89W power draw

However, I believe that we have just 4 weeks more because difficulty is going to be increased x2 in the next 2 biweekly shifts, so possibly the consumption will be over the BTC earns. Well, I waiting my BFL Single SC... :-)

Im confused as to where to find that information in gpu-z,  the vddc voltage?
