Hi,

I have a problem with my new Sapphire 7950.

Whatever the config I try, the computer will eventually shut down (except for very low kH/s)

600 kH/s the computer will shut down
500 kH/s will work for 1 min then the computer will shut down
400ish will work for 10-20 mins

PSU :  antec truepower 2.0 550W
4 GB ram
sdk 2.9 cat 13.12


I tried multiples settings but it always eventually shut down.

any idea what the problem could be?

Hi,

I don't know who to contact for this issue, but I entered a Coinex.pw MOON address to deposit my MOON coins (before the auto-payout for this coin was enable). It says on trademybit that the coins was transfered to my coinex.pw address about 6 hours ago, but I still have 0 MOON. Any idea why it takes so long? There no "contact" option on Coinex to contact them...

Hi,
I have a NVIDIA GTX 670 in my main pci-e 16x port, and a Radeon 5970 in my 2nd pci-e 16x port.

I'm using my 5970 for mining.

The problem is, when I play any game, the game use BOTH gpu. So since my 5970 has max alloc 100%, it takes all its power to mine, making the game lag...

Anyone know how to "disable" the radeon card for everything except mining?

Thanks

Hi,

I saw many volt/clock setup for this card, but with low memory clock for SHA-1 mining.

For scrypt mining, I noticed memory clock directly affect the hash rate.

So my question is : to lower this GPU temp and keep about the same hash rate, what voltage and clock do you use?
Note : i want the fan to run as low as possible since it makes a lot of noise!

Stock is : 725 core, 1000 memory, 1,05V.

thanks!
 

I have a nvidia GTX 670 as device 0, main GPU that i don't want to mine with,
and a Radeon 5970 as device 1, with a dummy plug. (this GPU has 2 cores)

i use the command line : cgminer --scrypt -d 1 -I 10 -o "pool infos"

When i run the .bat, the cgminer screen goes black.
On GPU-Z, i see that one core of the 5970 is working, but the other core is at 0%.

CGminer : 3.7.2
SDK 2.9 (also tried 2.6)
Catalyst 13.11
Windows 8.1 64bit

CGminer worked great with only the Nvidia GTX 670 plugged in (low hash rate but everything was working).

Can anyone help me? I want the GPU to work on both core ofc. Thanks

EDIT : The problem would be the same even if i wasn't scrypt mining...

I ll post here until i'm unlocked on other sections :

I installed the lastest cgminer, AMD SDK and catalyst.
