5 ns, huh? So, the ram doesn't have much headroom for oc-ing, it would seem.
I got the card installed and I'm running ATI Tool artifact scanning mode for 30 minute intervals as I increase the ram speed in 5 mhz steps. So far, its stable and artifact free at 210. When I seemed to have reached the max stable ram speed with AIT Tool, I'll run it through the paces with Aquamark3, 3DMark2001 and 3DMark03. Then I'll repeat the process to find max core speed. Does that seem reasonable?
You know, I experienced something weird in trying to install drivers for this card, though. The card would not recognize the latest DNA modded driver but it would recognize the latest official Catalyst Driver from ATI's website. Anybody have any insight here?
