Alright, well I just got a new cpu cooler/fan, thermal paste, and a second gig of memory. Now my system specs are: Intel Core 2 Duo E6300 @ 1.86 2 gigs corsair xms 2x1gb ram ddr2 800 Gigabyte GA-965P-DS3 XFX 7900GS Anyways, on the stock hsf/cooler I was able to go straight up to 333fsb instead of stock 266 fsb, but put it back down because I needed a new cpu cooler. I went ahead and ordered the Freezer 7 Pro, Arctic Silver 5 Thermal Paste, put it on, put the second gig of same ram in, and system dropped about 10 degrees C. The problem is now I can't overclock my cpu at all! I can't even put the fsb at 300 mhz, and everytime I try to change the voltage the system won't start. It will just restart about 3 times, go back to default settings, and nothing changes. I was able to change the FSB up to 333mhz with a stock cooler and 1 gig of corsair xms ram ddr2 800, but with the new hsf and second gig nothing...any help?
