Slow Ram causing I/O errors?

I have a 1U server with IDE drives that I've struggled with for many months. I keep having problems with drive errors. If you search My Posts you'll see topics about the history with this box. I sent back the first 2nd HD for bad sectors and replaced with a new HD different brand and had similar problems with it as listed below. Now I'm using only the first original IDE drive (not the one that went bad).

Where I'm at now is I'm getting an occasional I/O error which is means a corrupt MySQL table. I run a daily backup so I have at least a 24 hr window to go back to to get uncorrupted data if I'm watching the size of the backups in my daily email to know something didn't backup correctly.

What might be a problem is the RAM. I have 1 GB of PC2100 RAM (2x 512MB) on this box, but it seems most of the RAM is being used during very low loading.

Can slow RAM cause I/O errors? Would replacing 1 GB PC2100 with 1 GB PC3200 (one stick allowed on P4S61 MoBo) improve any of this?
