My cards are working at 74-77C. I Lifted the cards out of the chassis by using pci extenders and a wooden frame. There is also a big fan facing the rig. These cards definitely win the prize for the best toasters of 2013.

Topic: CRAP XFX 7970 ~380 hash - page 2. (Read 2545 times)
Well, I brought down the core to 855 and mem to 1575 which jumped the hash up to 529ish. BUT the card is now running at 88 C which is unacceptable. I swear XFX made a shit card here. Their new support site is the worst thing ive seen too.
I would change the intensity if the temp didnt skyrocket.

Yeah I'm using a xfx 7970 black edition with a 380 hash. pretty sh*tay.
any suggestions?
win 7,
--shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256 --lookup-gap 2
clocked from 855 to 1025 and mem 1475 to 1575. For some reason msi afterburner will not allow me to clock memory past 1575?
thanks!

Your intensity isn't very intense.
I agree that those cards are not the best but you have to admit that they where good bargain and they have good return rate.
I run three of them at 645/675/675. these are my prefs:

Something to try:
Reduce the mem clock and then try to find the sweet spot again. Worked for me on my 7970 Gigabyte cards. I couldn't get a Kh rate above 550 at mem clock 1600. I reduced mem clock to 1500 and found the sweet spot with a 1050 eng clock. I'm sitting at 720Kh/s now with 1 card.
Edit: Actually I have 2 7970s cards in the system and can get 720K on the second card when running by itself and 680K from each card when I enable them both. Still trying to figure this one out. I just made a post about it. I have a XFX 7970 that I will be adding to this rig when I get the riser figured out. I'm still a newb at this but from what I've seen so far you might not be able to get the "full" hash rate out of a card that is your primary card in the system. At least that's what I've experienced so far.
