Is there a trick to installing this. I turned off the printer and installed the memory but it freezes up the printer when it's installed.

It could be a DOA ram or memory was not align correctly with the socket. Please remove the memory from the socket and reinstall. If the problem persists, please request a return from your order page. Thanks!

what does ddr2 and dimm represent? I can not figure what I need.

First DIMM stands for Dual Inline Memory Module which has a 64 bit data path and is generally the standard for most current computer systems. The pins on either side of the module are separate connections. DDR2 SDRAM is a double data rate synchronous dynamic random-access memory interface. It references a specification for how the memory operates as apposed to a DDR or DDR3 specification. DDR2 DIMMs are neither forward compatible with DDR3 nor backward compatible with DDR.What you need depends on the specification for the system/device you are looking to add memory to. In my case the specification was for a HP Color Laserjet CP2025 printer.

Great Memory Expansion modules

My HP 1525nw was failing print jobs due to insufficient memory. I found this expansion card and installed. So far, all is working fine!

Perfect!

I searched around online as to the type of memory needed and then found this online. This was perfect - easy to install and works great. I know basically nothing about computers and I was a little unsure about trying to install the additional memory for my printer, but all is well!

Ordered quantity 3 of this RAM under a company account, tried all 3 in a HP P2055dn and all 3 times gave a B0605 error on startup. The printer's firmware is updated to the latest version. Removed RAM, went back to normal.
