Just got done water cooling my card today, and it's staying at ~ 31C.



580mhash/s / 99.484W = 5.83Mhash/W Cheesy

factoring in 15% loss in power ->

580/(99.484*1.15) = 5.069 Mhash/W o.o

Nice!  You should post pics of the gear, I'd love to see that! Smiley

Have you measured from the wall or rely on software reading ?
Also wouldn't Diablominer give you around 650Mhash ?

You should try the latest version of CGMiner (or DiabloMiner).  Like ice_chill said, you should be getting a little more hashing speed.

Out of curiosity, how are you getting 700MHz memory?  The lowest I'm able to force it to is 800.  Tried CGMiner, MSI Afterburner (with unofficial overclocking enabled), and CCC.

I have not measured from the wall; however, HWiNFO64 has been known to be pretty reputable.  Remember the 7 series performs at it's peak with lower temps. (less leakage - superconductor theory)

Here are some pictures:

According to WIKI hardware comparison you can squeeze 820Mhash if you overclock to 1290 core.

You need a massive increase in voltage though :p

I'm at .985v atm.  It's stable at .955, but I figure a little extra juice wont hurt.

Nice photos. When you can, would you mind going over what you used to change the mem clocks?

factoring in 15% loss in power
580/(99.484*1.15) = 5.069 Mhash/W o.o

Why factor out 15% again?

I'm using afterburner beta 15.  Set clocks to what you want, then go into cgminer and adjust the memory clock to < what you have set in after burner.  I usually type 300 in afterburner then 300 in cgminer.

Ah makes sense. Forgot you were reading off on-card power measurement devices. Thanks.

I like your radiator setup. I have a similar quad radiator setup on top of my Antec P280 Smiley

Personally, I wish it would fit in the case :p

But it will do.  Waiting for the "what the hell is that monster" stare I'll get when I move out of my dorm :p

Also, how do you recommend I thread my fan cables inside of my case?  This case was build for an internal skinny 240 rad, lol.

I actually thread the molex connector out the watercooling tubing holes then I just cable-tie them together and let them hang out the back. If I wanted to make them look even neater I'd prolly buy a sleeving kit.

I'm a jerk when I go to LAN parties and run all 4 of my Ultra Kaze on the radiator at 3000 RPM then put on my noise-cancelling headphones Smiley

Good idea, but I have my fans connected to my pwm ports :p 2k rpm fans are alittle loud to sleep with.
