Think I figured it out - bad chip maybe?
Refer to my previous post for system specs.
Here's my current situation.
Whenever I try and install large programs containing large individual files (ie: World of Warcraft)after a short period of time I get an error which says the file copied was corrupted and cannot be read.
At first I suspected my SCSI controller and/or drives (controller: Adaptec 19160; drives 2x Seagate Cheetah 15k rpm/36.7gb). But I've had these drives and the controller for about two years in the previous system with absolutely no issues. Improbably they were "e;suddenly"e; damaged, but not impossible. So I sourced another Adaptec 19160 controller from my office and another SCSI160 HD (identical Seagate) to attempt to install software to as well. Exactly the same error at roughly the same point.
I ran SiSoft Sandra's Combined Performance Index Wizard. It also could not test my File System because the files themselves became fragmented on every drive it tried (either of my SCSI160's and my external WD 250gb FireWire drive).
Oddly enough, I can copy huge files (I copied a 14gb video capture file) from one drive to another with no problem (I checked it for fragmentation after, and it was not).
Here is what I think is happening.
Installable files are typically copied to system memory, then decompressed (or whatever the installer for that application chooses to do) and copied to the specified drive/directory. When I try to install programs that decompress and/or copy large files, I get the fragmentation error. I believe my system memory is somehow causing this file fragmentation.
I have been able to install smaller applications with no trouble (ie: Photoshop CS2, Office XP; Office 2003 gave me the same file error).
So at this point I'm afraid I either have bad memory or the incorrect memory for this system.
The most recent timing's I tried (and what I'm currently running) are: 5-5-5-15-2T.
Thanks again for your help in advance.
