Hey dudes and dudettes.

This is my first time here and i gotta congratulate you on this nice comunity from what i`ve seen so far. I have a couple of questions and maybe you guys can help me out:

I recently purchased a Gainward HD 4850 (non-GS version with the black plastic) and i`m a bit confused as to how you should OC that thing cos i tried that using the CCC Overdrive option with Auto tune, and after it tested the frequencies and passed them, the next thing was to freeze my PC and show green vertical stripes on the screen. Is it because of the PSU? I have a Gigabyte Superb 460W. Or something else? I also mention that the black screen problem also arrised but only at the begining and only in Crysis. After searching for a few answers with Saint Google, i changed the PCIe frequency in the mobo BIOS and the problem was solved. I played Warhead for a whole day without anything crashing down all around me.

Another thing is, also in gpu-z the fan speed always shows 6% with 1 RPM, nomatter what the load. That can`t be right, so i was wondering if there is something to be done.

Allrighty then. That about covers it.

Thanks in advance and keep up the good work. Cheers

Sapphire has chosen to remove the temperature based fan control mechanism from their cooling solution. The fan will always run at the same speed, no matter if you run an idle system in Antarctica or under full load in the middle of the Saudi Desert. When asked, Sapphire replied that they "noticed that on many systems the problem is that the fan always starts and stops - at different temperatures. So we decided to always run at the same quiet fan speed".

How many MOBO product that have Slot 3D card ver. 2
