System-specific memory for legacy HP printers

This 256MB SODIMM module is built for HP LaserJet 9050 series printers including the 9050Mfp, 9050, 9050Dn and 9050N. It provides a direct memory upgrade for these specific models. The part is new and supplied as a single stick. Compatibility is guaranteed by the manufacturer for the listed devices.

100-pin PC100 SDRAM interface

The module uses a 100-pin SODIMM form factor operating at PC100 speed with a CAS latency of CL2.5 and 3-3-3 timing. It runs at 2.5V as non-ECC unbuffered SDRAM. This exact interface and voltage combination determines whether the part will function in the target printer.

Low-power operation in printer chassis

The memory draws minimal power at 2.5V and has no heat spreader or active cooling. It operates passively within the printer's enclosed chassis under normal workloads. No fan noise or thermal management is required for this component.

Questions about this item

What does the PC100 rating mean for actual performance inside an HP LaserJet 9050?

PC100 runs at 100 MHz with CL2.5 timing, so the printer controller can fetch data at the full bus speed without wait states.

The module uses a 100-pin SODIMM interface — what does that limit?

The 100-pin SODIMM slot only accepts unbuffered, non-ECC SDRAM at 2.5 V, so registered or DDR modules will not fit or function.

Will this stick physically seat in the HP LaserJet 9050 MFP memory slot?

Yes, it is a 100-pin SODIMM measuring the standard outline for the 9050, 9050Dn, 9050N and 9050Mfp printers.
