Targeted DDR1 SODIMM upgrade

This 512MB DDR1 333MHz module is built for Xerox Phaser 8500/Dn, 8550, 8550/Dp, 8550Dt and 8550Dx printers. It fits the 200-pin SODIMM slots in those devices and uses unbuffered, non-ECC chips at 2.5V. The kit contains one stick for a single-slot installation.

Steady operation in print workflows

CL2.5 timing with 3-3-3 cycles keeps latency predictable during long rasterising jobs. Major-brand DRAM and the PC2700 rating sustain the rated 333MHz throughput without throttling when the print engine requests large buffers repeatedly. The module runs at standard DDR1 voltage so thermal load stays consistent.

512MB single-stick capacity limit

Each socket accepts a maximum of 512MB and the system tops out at 1GB across two slots. This stick fills one socket at the per-slot ceiling, so a second identical module is required to reach the printer’s full memory potential. Buyers needing more than 1GB total cannot use this platform.

Questions about this item

How much heat and power does the 2.5 V DDR1 module draw during continuous operation?

The stick runs at the standard 2.5 V for DDR1 SODIMM; with no heat spreader and a modest 512 MB capacity, it adds minimal thermal load to the printer's memory slot.

Which printer models must I already own for this CM64642700SO16C upgrade to work?

It is validated for Xerox Phaser 8500/Dn, 8550, 8550/Dp, 8550/Dt and 8550/Dx systems that accept 200-pin DDR 333 SODIMM memory.

Will this 333 MHz CL2.5 module run reliably alongside any existing DDR1 sticks in the second socket?

Yes — the printer supports two sockets up to 1 GB total, and this unbuffered non-ECC module matches the required 3-3-3 timing for mixed-population operation.
