Ram upgrade Pavillion ze4200

By James Hebner ·
I have recently upgraded the above laptop to two 512MB SDRAM modules, giving 1GB.
The system only sees 512MB. I have tried the modules in both slots. Any ideas how to solve this?

RAM Density

by TheChas In reply to Ram upgrade Pavillion ze4 ...

I suspect that you have a RAM density issue.

To verify this, install just 1 of the new 512MB modules and you should only see 256MB of RAM.

If so, what you need to do is find some older technology lower density RAM for your system.

A good rule of thumb is that low density RAM has twice as many chips as high density RAM for the same size.

Another possibility is that you did not enter BIOS setup and allow the BIOS to recognize the new RAM.
