Hello,
I purchased a P4 3.06 GHz processor for my Dell Dimension 8200. The seller said this processor would work with all Dimension 8200s and 8250s. I installed the CPU and the system stopped the boot and gave the message "processor speed mismatch." The seller suggested installing the latest BIOS to resolve the issue but I'm not sure this will work. I read in one place that the 3.06 will work if you have the 850E chipset but not the 850, which I have (according to the CPU-Z program although, based on the ship date, it's supposed to have the 850E). That person said the 2.8 P4 would work, however. I don't want to bother installing the latest BIOS if that won't help; I understand that the main reason to do that is to resolve a compatibility issue with a particular sound card, which is not the problem.
