Auslogics Disk Defrag & Ultradefrag

I have been using and recommending Auslogics Disk Defrag for years, and particularly like the ability to move system files to the fast part of the disk.

I started using Ultradefrag for the boot-time ability to defrag the pagefile. The program runs quickly.

Mixing PC Memory Speeds

The PC configuration had been upgraded to add two 1 GB memory sticks. The new memory had faster timings than the original two 256 MB memory sticks. The PC adjusted the speeds to match the older, slower memory chips.

Memory overview. Note the speed is 199.5 MHz and FSB:DRAM is 1:1. Also note the clock numbers.

Four sets of memory:

I removed the two original memory chips, and the memory speed is about 1/3 faster at 266 MHz and with faster clocks.

Windows Update With Older ATI Hardware

The ATI drivers from 2006 have had a few minor glitches. Repeated attempts to upgrade through Windows Update and through Windows Device Manager resulted in no available upgrades.

AMD (owner of ATI) has this page to upgrade to drivers from 2010.

The upgrade went smoothly.

After the upgrade I used Windows Device Manager to look for an additional upgrade. It found an "upgrade", which was a downgrade to the previous version from 2006.

This was cured by reinstalling the ATI upgrade.

Boot from the installation CD and start the recovery console.  Use the fixmbr command to repair the boot record.

Overheating Laptop

A laptop that would intermittently turn itself off has been diagnosed as overheating.  Even with multiple underside fans running, the laptop could not keep itself cool.  The small form factors don't tolerate dust buildup.

Note the internal temperature of 63C in this picture from SpeedFan.
