Hi, this is my first post.
I recently upgraded from a Core2 Duo E6850 3.0GHz to a Core2 Quad Q9550. I bought this processor because it is on the DP35DP compatible processor list on the INTEL site. Big mistake. Anyways, after reading on the problems others have had I down graded to 571 BIOS and it seems to be booting now.
However, I do have one issue still. My Windows 7 64 bit used to have speed stepping in running one my Core2 Duo, but seems to be pegged at 100% cpu frequency on this now Core2 Quad. I have tried setting in the Power settings, with no help, and there is not speed stepping setting in the BIOS.
Anyone seen this, and know if I can get this working??
Thanks again for you help.
