SAPPHIRE 100352-4L 7950 Power Draw

[boozer]

I have seen voltage and power draw for this card all over the place. 1.17v to 1.25v and 200 watts to 305 watts.  Probably due to different clocking etc...

I believe the stock voltage is 1.25v.  Can someone running at this voltage tell me their hash rate (Scrypt and or SHA) and power draw at the max OC for this card?

As a side bonus, can the voltage for this card be changed in Linux or does one have to flash the bios for a lower voltage in Linux?  I heard cgminer/atitweak etc dont change the voltage in linux.

I'm getting around 650-660khash/s for scrypt on my vapor-x 7950.  1.25v (stock), Core @ ~1100MHz, RAM @ ~1500MHz.  Not sure about the power draw but its probably around 300w.

I don't know about Linux voltage adjustments. I thought you could adjust with AB in Linux.

I run 2 of these cards. I was running at 1.25v (stock volts) and 1100 MHz, RAM 300 MHz, with (1)575, (2)550 Mh/s and the setup pulled 640-650 watts.

Yesterday I stopped using AB and did a direct cgminer config. I am now running 0.975v, 1100 MHz, RAM 300 MHz @ 605 Mh/s for each pulling 600 watts.
