I have an old HP Proliant DL320 G5 with 2x 1GB of RAM. I would like to swap out the old ram and install 4x 2GB of RAM to bring it to the max capacity. The manual calls for PC2-5300 unbuffered modules.
The current RAM label reads: 1GB 2Rx8 PC2-5300E-555-12 HYMP512U72CP8-Y5 AB-C 0716. I know this means they are 1GB DDR2 PC2-5300 unbuffered with ECC. However, when I search eBay, Amazon or other sites, I find parts labeled PC2-5300R or PC2-5300P and the description reads that they are unbuffered and registered with ECC.
What I would like to know, if I fill all the DIMMs in my Server with PC2-5300R, PC2-5300P or PC2-5300 unbuffered, registered with ECC, if the Server will accept the RAM modules, or if I need to have PC2-5300 unbuffered, unregistered with ECC?
