4GB DDR3 1600 UDIMM for HP EliteDesk

This single 4GB DDR3 module runs at 1600 MHz with CL11 latency and 1.5V operation. It uses a 240-pin unbuffered non-ECC design built to JEDEC standards. The kit targets owners of HP EliteDesk 700 G1 SFF, 700 G1 Tower, 705 G1 SFF, 705 G1 Tower and 705 G2 SFF systems seeking a straightforward capacity increase.

Who this suits and who should look elsewhere

The module suits users upgrading the listed EliteDesk models where a 240-pin DDR3 DIMM is required. Builders needing ECC error correction, registered signalling, voltages other than 1.5V, or capacities beyond 4GB per slot should look elsewhere. Systems that accept only SODIMM form factors or a different pin count are also incompatible.

Deciding specification — 240-pin DDR3 1600 CL11 1.5V

The decisive factor is the 240-pin DDR3 interface running at 1600 MHz with CL11 timing at 1.5V. Verify that the target motherboard specifies this exact speed, voltage and pin layout before purchase; a mismatch in any of those parameters will prevent the module from functioning.

Questions about this item

Does this 240-pin DDR3 UDIMM need a motherboard with a 240-pin DDR3 slot?

Yes, it fits a standard 240-pin DDR3 DIMM socket on a desktop or workstation board.

Can I add this 1.5 V CL11 module to an HP EliteDesk 700 G1 that already has memory installed?

The module is tested for those EliteDesk models and will run at the speed of the slowest installed stick.

How do I confirm the 4 GB stick is recognised at PC3-12800 after fitting it?

Check the BIOS memory summary or Windows Task Manager to see 4 GB at 1600 MHz CL11.
