Hi.

XP upgraded to W7 Professional.

Presently I have 2 x 1GB: Details from the chips> 1GB MT18 BHTF 12872AY 667D4 200718 BZADRM8004: 1GB2XR8 PC25300E 55512G0: DDR2 667CL5 ECC.

2 x 2GB: Details from the chips> 2GB CT25672AA80E M18FH: 2GB240-PIN 256MX72 DDR2 PC2-6.

A total of 6 GB RAM.

This Desktop can take a maximum of 8GB, so I want to add another 2GB, but I know mixing RAM can cause instability. I am guessing the the markings on chipsets indicate alternative types.

Some guidance will be much appreciated. Thank you.

The HP xw4400 WorkStation desktop has 4 DIMM slots and supports the following RAM configurations:
If DDR2 modules are the ECC type, it supports 8 GB of RAM.
If DDR2 modules are the Non-ECC type, it supports only 2 GB of RAM.

If all 4 DDR2 modules you have are the ECC type, then you should be able to increase it from 2 GB to 6 GB.

Thank you. There are 6 GB ECC. Cant't mix, so I am removing those and getting 4 x 2 GB.
