CFX works only in FULL Screen. It does not support window mode so the point is valid.

The specifications say up to 120*C
However, For 24/7 use I would keep them below 90*C if possible.

Great guide but I got a crappy 4890, won't even go above 900MHz Core without artifacts. Voltage isn't going to help either. No 1GHz for me, let alone 900+

Syrillian, You will never be replaced. Rest easy friend.

No worries mate. Your guide is amazing. I wish you wrote it in sooner. I am trying to break the 23000 mark with my CFX HD4890XXX cards and I spent quite some time modding the BIOS, configuring GPU TOOL when Afterburner, already installed on my system, needed a simple tweak. Voltage in Aferburner seems to have a limit. For example, to run 1050/1200 on my ATI cards I need 1.43V and Afterburner does not allow that. Would give rep but you don't have the button.


Regarding max temp, 120 is for the VRMs not for the GPU. The GPU will start dying at 100 degrees.
