4GB DDR2 kit for HP dc5850

This 4GB kit contains two 2GB DDR2 DIMMs rated at 800MHz PC2-6400. The modules are unbuffered, non-ECC and run at 1.8V with CL6 timings. They are built specifically for the HP Compaq Business Desktop dc5850 in both SFF and Microtower chassis.

Suits dc5850 owners adding matched memory

Buyers upgrading an HP dc5850 SFF or Microtower gain a tested dual-channel pair that the supplier guarantees compatible. Systems needing ECC, registered modules or a different DDR generation cannot use these DIMMs, so verify the platform before ordering.

Simple DIMM installation on a legacy platform

The 240-pin modules seat in the desktop's standard DDR2 slots; no heat spreader means they fit tight SFF bays without clearance issues. Common problems include mixing with existing modules of different speed or rank, which can prevent the system from posting.

Questions about this item

Does my HP dc5850 SFF or Microtower need a specific motherboard revision to accept these 240-Pin DDR2 DIMMs?

The kit is built for the HP/Compaq Business Desktop dc5850 SFF/Microtower platform and uses the standard 240-Pin DDR2 interface that the system provides.

Will these CL6 1.8V modules run stably if I keep the original slower DDR2 sticks installed in the other two slots?

The board will operate all populated slots at the speed of the slowest module, so the original sticks set the pace while the new pair simply match that timing.

How can I confirm the 4GB kit is running in dual-channel mode after installation?

Enter the system BIOS or use a utility such as CPU-Z; both will show the memory operating at 800 MHz with dual-channel status when the two DIMMs are seated in the correct paired slots.
