Overcloking a Compaq Evo N800w ?
Hello,
I own a Compaq Evo N800w laptop that's supposed to run at 2.2GHz but SiSoft Sandra reports 1.196GHz... I'm not familiar with overclocking issues but I thought it would run at nominal speed. According to CPUBench2003: - chipset is P4N Northwood 0.13microns - socket 478 (PCA478 socket) - bus type GTL+ Technology - Family/Model/Step F/2/7 - Freq. range 1.3-2+ GHz My question is: how to reach 2.2GHz and is it normal it currently runs @ 1.2? Thanks for your help to a newbie... Olivier -- ----------------------- Olivier |

Since your computer is a laptop it has not facility for the user to change
items like the CPU speed. SiSoft Sandra, though it has improved over the years, sometimes delivers incorrect information. My thought is that SiSoft Sandra is reporting in error. There really is no way that a 2.2 GHz Pentium 4 could run at real 1.2 GHz, as it was made only as 400 MHz FSB. It might be that the CPU is overheating and being throttled to a much lower average speed (by starting and stopping), or that battery saving is invoked to the point that the average speed is lessened that much. Three options: 1. Compare the SiSoft CPU benchmarks reported for your notebook with the quantities reported for 2.2 GHz Pentium 4 Northwood (or 2.4 GHz), if it is near the performance of such a CPU, then SiSoft is in error with the CPU speed report. 2. Download another Utility to check your CPU performance, i.e. the 'Intel Processor Identification Utility', available from http://downloadfinder.intel.com/scri...3&DwnldID=7838 . 3.

I'll try that
Thank you Phil. BTW, the benchmark results displayed by Sandra as well as CPUBench2003 are desperately low compared to a REAL 2.2GHz system so I didn't suspected a misreported speed. I'll try the Intel SW and tell you what it says. Stay tuned Phil Weldon a pensé très fort : Since your computer is a laptop it has not facility for the user to change items like the CPU speed.

This laptop run at two speeds...one lower when on battery, and a higher speed on AC power. You are measuring the speed when running on battery power. Read the specs in the beige box at the bottom of this review. It runs at 1.2Ghz on battery power. http://www.pcworld.com/reviews/artic...,110531,00.asp |

Then check the notebook manual or contact HP/Compaq for information on
setting the power options for your system. Phil Weldon "Olivier" wrote in message ... Augustus a formulé ce samedi : "Olivier" wrote in message ...
