Got my e1705 last week; rev 1 7900 gs;
running stable at firstname.lastname@example.org (shader core-geometry core as I used a delta of 40) though my memory has artifacts as low as 545 :/.
On the other hand stress testing it right now (Orthos + ATITool) at 1.06v, same clock/mem settings. The weird thing is, even if I bump it to 1.24v, I can only get to 615 stable. Maybe it's an issue with 90w power supply or single pipe (1.24 Atitool load temps get to 90c+; 1.1 gets to mid to low 80s).
Love the card and the information on this forum
EDIT: Bah, seems atitool is no longer the best stress testing device. 1.1v which worked for over 16 hours stable on scan artifacts w/ orthos blend running occasionally causes video driver resets in vista. Testing 1.14v now with games :/
