Agreed, I am curious on the hashrate. I've heard people say 1200ish but I wonder if those are unoptimized hashrates without proper settings.
I have hit 1330-1340 mh/s using msi afterburner on my sapphire 7990.
100mhz ram, 0% voltage, using guiminer.
If linux or cgminer its probably possible to hit quite a bit higher. Right now I run 1240-1285 mh/s range 24/7 for weeks. Temps 79C or below. 3 GPUs.
*note I am only giving results for my 7990 card.
It can probably hit 1376-1400+mh/s...yes I believe its possible.
Do u mean 1330-1340 mh/s on each 7990 card? can u share to me how you did that cause i'm only getting around 1150mh/s per card...thanks
sorry for being such a newbie but what is stock cooling and how do you open the case for a 7990? I have two xfx 7990 but temps gets to as high as 95 degree C with a hash rate of around 500MH/s.
Can someone please help me with the best configuration to maximize hashing power.....I did pay big $$$ to get them..thanks

Stock cooling is the cooling already on the card. As for people referring to open case they generally mean taking the side(s) off of the computer case. For dual 7990 you also want a big fan aimed into the general pc case, 500Mhash sounds like they're throttling back due to getting too hot!
Thanks Tom_o!!! Do I still need to use a crossfire for 2 xfx 7990? Also, just wondering what type of fans are the best to cool down the cards?

can u please! please! post a step-by step solution to exactly what you did. i am having the same problem with XFX7990. hash rate keeps dropping from 500MH/s to 100KH/s after 4-5 minutes after i get a " Communication Problem" message. I am not a programmer so I'm kinda not familiar with hotkeys..thanks
I am having similar problems with XFX 7990 using GUIMiner. The hash rate fluactuates and then after 4-5 minutes I get a "Connections Problem" message and then the hash rate drops from 500MH/s to 100KH/s. Anyone know how to fix this? pls advise...thanks
Re: Sapphire 7990 Extremely Hot Running CGminer - Need Suggestions
i am using GUIminer with my 7990 and keep getting a "problem communicating" error every 3-5 minutes interval. Anyone know why and how to fix it please let me know.....my hashrate drops from 500GH/s to 100KH/s when this happens....

can someone help me with my GUI miner using a 7990? I keep getting an error message saying "Problems communicating" almost every 4-5 minutes and then the hash rate drops from 500GH/s to 100KH/s. Thanks for your help in advance
