Anyone know? Which version of the drivers works best for KKDongle LBF?
Windows 7 x64 + 2x 5970 (crossfired)

Hi from my test best is v10.12 on it LBF is most stabile and without gpu use drop always 99% and without hang.

I have Ati river 10.11
2 X 5970

Maximum time for calculation is 35h/phone

It need to test, because many bugs come from AMD.
latest beta drivers are 11.4, but of course they add new bug to CAL > "device busy" and is a bit slower(if compile new kernel). Please users to share their experience here to discover new driver.
Another "new feature" is that HD6990 is still not fully supported, in OpenCL (future of GPGPU) still support only 1 GPU. In CAL (lower layer) fortunately is possible to use 2 GPUs but to have second GPU working, user need to plug dummy DVI adapter(probalby version with 2 DVI ports).

about time, some user example 2xHD5970 850MHz + water colling blocks

b.r.

for me 11.3 is working on 2 x 5970 gpu, without prob.

and it is 100% stable

clock are on 725 mhz and working on 6000 hash

What is max time for 2x5970 OC Core to 850MHz?

Hi!
Im using 10.4 version and cards is on 800MHz. I got 6400 hash! Now seem to be the system is stabile!
Is it not dangerous using 800 Mhz or better only 725?

If temp no more then 75 C then you can use card on 800 Mhz without problems.

My pc temprature is 65-67 degree, on 725 mhz

but when i switch it to 750 or any above.

display drive stop responding error occur ..

I tried with all drivers

11.3
11.2
11.1
10.12
etc.

Any Special Requirement ?

I don't know maybe you PSU to low power got and when you do higher frequence it tell not have power and becosue this you got this massage ?
My card work on 840Mhz without problem on 800Mhz work even without higher voltage on core. I got PSU 1050W with 4 line 12V+ everyone with 30A power.

gsminfo · 04-09-2011, 17:01

Really problems here can cause only temps and PSU efficiency and performance. If U will overclock card too much but temps will be bellow 100C(Absolute max - AMD specs) then U can only crash driver, nothing more, GPU will not burn. Of course GPU have own overclocking limit too

If U do not changed GPU voltage, but only clocks, so U should keep tracking temps only to be in safe range(better do not go higher than 95C).
If U get system reboot then probably PSU cannot handle it. Remember that PSU wattage cannot be compared 1:1 for power what U need, but U must get about 80% of PSU power. For example U have 1000Watt PSU and UR system(full, cpu+hdd+DVD+gpus etc) need 950Watt then U need at least 1200Watt PSU. Better is to not overload PSU and let it work at 100% of it potentian, because PSU is never calculated to work like this way. Buy one , strong and good quality PSU

Also some differences maybe between different card manufacturers like MSI<>ATI, or just specific model. But for sure U can hit 800MHz even on stock cooler(like me).

and what memory speed is set when U overclock GPU to 750MHz?
