Purpose-built printer memory

This 256MB SODIMM module is designed for HP Color LaserJet 2505, 2605Dn, 2605Dtn and 2700 printers. It uses 100-pin PC100 SDRAM technology running at 133MHz with CL2.5 timing. The unbuffered, non-ECC stick operates at 2.5V and installs directly into the printer's memory slot.

Sustained print workloads

Under continuous print jobs the module maintains its rated 133MHz speed and 3-3-3 timings without throttling. The major-brand chipset delivers stable data throughput for complex graphics and duplex tasks. Single-stick configuration means the printer controller sees one consistent memory bank throughout long queues.

Thermal and power profile

With no heat spreader the DRAM runs at its specified 2.5V within the printer's enclosed chassis. Passive airflow from the printer's internal fan keeps temperatures in the normal operating range. Power draw stays low, matching the original equipment specification for these LaserJet models.

Questions about this item

How much power does the 256MB PC100 SODIMM draw when the printer runs continuously?

The module operates at 2.5V unbuffered SDRAM, a low-voltage design that keeps heat minimal during all-day printing.

What must the printer already provide for this 100-pin SODIMM to function?

A free 100-pin SODIMM slot accepting PC100 133MHz non-ECC SDRAM at 2.5V.

Will this stick work in an older HP Color LaserJet 2505 alongside any existing memory?

Yes, it is compatible with the 2505, 2605dn, 2605dtn and 2700 models; add it to the open slot for a 256MB upgrade.
