I just started a Q6600 @ 3.1GHz running the A3 core with about 6600 PPD. My ETA is well within the completion time. I had this Q6600 @ 3.2GHz but with LinX the max load temp was 75C. I lowered it to 3.1GHz to bring the temp down a bit. I see my max load temps so far running the A3 core is 59C so I have some leeway. dhoshaw asked if anyone was running the new 196.34 beta drivers. Well I installed them on this new Vista 64-bit build. I don't know what the problem is but I couldn't start my second card. When this A3 core finishes I probably will revert to 190.62.
