1GB DDR2-667 DIMM for HP dc5700

This 1GB DDR2-667 (PC2-5300) module is built for HP/Compaq Business Desktop dc5700 small-form-factor and microtower systems. It uses a 240-pin unbuffered non-ECC design running at 1.8V with CL5 5-5-5 timing. The single stick is suited for basic office workloads on supported legacy platforms.

Suitable for dc5700 upgrades.

Buyers restoring or expanding memory in an HP dc5700 SFF or microtower will find this module matches the factory specification. It is not intended for systems that require ECC error correction, registered buffering, or higher-capacity dual-rank configurations beyond the single 1GB rank provided here.

Verify DDR2 slot availability and 1.8V support

Before ordering, confirm the motherboard has a free 240-pin DDR2 DIMM slot and that the BIOS accepts 1.8V non-ECC modules at 667MHz. The dc5700 family includes several chassis variants, so check the exact model label to ensure the slot count and voltage match this stick.

Questions about this item

Will this 240-pin DDR2 DIMM fit in my HP dc5700 SFF or Microtower?

Yes, the module is listed as compatible with the HP/Compaq Business Desktop dc5700 SFF/Microtower and other dc5700, dc7600, dc7700, dc7800 and dx2255 models.

Can I run this PC2-5300 stick alongside older PC2-533MHz memory in the same system?

The system will operate all modules at the lowest common speed, so adding this 667MHz DIMM to existing 533MHz memory will result in both running at 533MHz.

How can I verify the module is running at 667MHz with CL5 timings after installation?

Check the memory speed and timings in the BIOS setup or use a system information tool such as CPU-Z to confirm DDR2-667 operation at 5-5-5 latency.
