Topic: 3x7970 Mining Results. - page 14. (Read 61705 times)
this will be good as DeathandTaxes has triple 5970 rigs to compare with. All my 5970 rigs are 4 per, except one (3x5970 + 1x6950).
Power draw at the plug please!
I have 3 7970's that will be here tomorrow(if the fedex plane/truck doesn't crash and burn or a herd of angry hamsters hijack it and eat my gpus...).
I will post what hash rates I get with them along with power draw figures.
Any special requests post them here.
Just reserving this for now. :p
EDIT:
Wattage is measured at the wall plug as total system draw. Subtract the 224 Watts of the system idle from the total then divide by 3 to get individual 7970 power draw. Mining results are of 7970 power draw only. My power supply has about 92% efficiency but I did not factor that into the results.

EDIT2: Just remember that this is the wattage difference from idle wattage to load wattage(btc mining). Your results may vary.
EDIT3: Updated with watercooling results.
