I have an IBM xSeries 306. The system has been flawless until a week ago. It's a Pentium 4 Dual Core CPU. The CPU speed is 3.20 gHz. Now, it shows 4.26 gHz or 2.16 gHz when the POST screen comes up. Nothing in the BIOS is user configurable for this.
Anyone have an idea what's going on here? If it's not at 3.20 gHz, it runs slower.
