Do you have "Verbose" logging set in CGminer?

The temps are fine you could safely push a little more out of it and raise the thread concurrency and intensity

Hello

After looking around the web and trying out different configs, this seems to be the sweet spot for me with temps I feel that are extremely safe.

Here's all you need to know, tell me if I'm missing something

Sapphire Radeon 7950 Vapor-X Boost Ed.
Windows 7 x64, 2GB RAM on this system
Driver version 13.6 with
cgminer 3.3.1

OC settings, done with sapphire trixx
+11 Power Limit
1.150 VDDC
1150 Core clock
1250 Memory Clock
physical 'boost' button is ON

cgminer settings
"scrypt" : true,
"kernel" : "scrypt",
"shaders" : "1792",
"intensity" : "13",
"gpu-threads" : "2",
"thread-concurrency" : "8192",
"temp-cutoff" : "95",
"temp-overheat" : "85",
"expiry" : "1",
"worksize" : "256"

No SETMEM or other commands used with a bat file.
69 celsius on a hot summer night, ~80 VRM Temps, case is a HAF XB with case fans off, except for the left front one, all panels on.

As you can see in this bunch of pics, hashrate is around ~590. I keep this thing running 24/7 and it never skips a beat.

Let me know if you have some better config, I'd definitely be happy with a better one, but without going over 70-72 celsius.
Thought about posting it in the mining section but it's under 'Bitcoin' so whatever.
If it helps, I wouldn't mind you throwing a few LTC my way Roll Eyes

Cheers
