I have a new Shuttle K45 I put together and have a problem with the CPU speeds, it has a Core 2 Duo E6550 which is supposed to run at 2.33 GHz but it will only run at 1.86 GHz with the clock speed at 266 with a multiplier of 7, I of course get a BIOS error on boot stating that the CPU supports 333 and to set the BIOS to optimized settings, but when I do this the thing won?t get past POST, it just stays ?black? and I have to clear the CMOS jumper, I have tried 2 sets of RAM that are both on the supported list there are 2 Dual channel capable 1 GB sticks, I tried A-Data and now I have new OCZ DDR2 800 (PC2 6400) sticks, any advise appreciated.
