Wrong Bus Speed and Clock Speed Displayed After CPU and RDRAM Upgrade on Dimension 8200
Have an old Dimension 8200 I am in the process of upgrading. I have installed a 3.06 GHz Northwood and 2 GB of 40ns RDRAM. The system recognizes the CPU and the RDRAM, the correct amount of RDRAM and the correct processor speed is displayed in both BIOS and in System Properties in Windows XP, but the Bus Speed in the BIOS remains at 100 MHz (should be 133 and there is no option to change it) and the clock speed in System Properties is displayed as 2.29 GHz. Hyper Threading is enabled in BIOS. The machine is running fine, with noticeably more speed, but I have been unable to get those numbers up where they should be.
How can I get the bus speed and clock speed to be where they should? I have already tried flashing the BIOS and removing and reinstalling both the RDRAM and the processor, neither made a difference.
Thanks for any help you can offer.

It's probably the Intel chipset and not much you can do about that.

Adding a little info to Fireberd's post: The 8200 was built with two chipsets. Machines sent out before May, 2002, had the 850, while machines sent after that date had the 850E. The practical difference is that the 850 supports only a 400 MHz FSB. To get the 533 MHz FSB you require an 850E.

But if I had the 850 chipset, would the system even recognize the cpu correctly and the 40ns RDRAM? I was under the impression that the 850 chipset would only run wtih 45ns RDRAM...

The Dimension 8200 with a 850 Chipset and 400 MHz FSB processor will run with either 40 or 45 ns RDRAM, but the 850e Chipset with 533 MHz FSB processor requires the faster 40 ns RDRAM.
