Iv recently rebuilt my machine with a new mobo and cpu. The mobo is a Gigabyte 7N400 Pro nForce2 Ultra 400 and the CPU is an Athlon Barton XP2800+
All went well, and I installed the cpu fine with some arctic silver and new fan suitable for up to XP3200+
It all booted up fine, and its been on for 24hours now with no stability probs or anything, but the problem that I do have is that the chip is only running at 1250mhz instead of 2.0ghz.
I have updated the BIOS to the latest release, and also installed CPU-Z which shows the information below! Now the obvious error is that the FSB is running at 100.2mhz instead of 166. Iv entered the BIOS in advanced mode and changed the FSB to 166, which makes no difference at all! iv played about with numerous settings in the bios and it makes no difference to the clock speed or the FSB speed in CPU-Z
Also in the CPU-Z it says the release is C1, but im positive when I ordered it it stated Rev2 of the board! But im not sure how accurace CPU-Z would be for this?
My memory is 1gb of 3200 DDR400 but that is also showing in CPU-Z as 1gb of 3200 200mhz, but is that due to it being dual channel and me having 4x sticks of 256?
Any ideas or suggestions for the FSB problem would be mucho appreciated! thanks!
