Hi,<br />
We have a server that's running HP PC2-5300F-555-11-B0 memory. &nbsp;I purchased HP PC2-5300P-555-12-ZZ memory, and it doesn't fit... (the slot in the RAM doesn't match up). &nbsp;<br />
<br />
Not sure what the difference is... looks like one is &quot;555-11&quot; and one is &quot;555-12&quot;, plus one is 5300P and the other 5300F.<br />
<br />
Any idea?

HP memory - not fitting? (PC-5300F vs PC-5300P)

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
