System-Specific DDR3 Kit for HP rp5800

This 8 GB kit contains two 4 GB unbuffered DIMMs built to match the HP rp5800 point-of-sale platform. Each module runs at 1600 MHz with CL11 timing at 1.5 V. The non-ECC design suits the commercial desktop workloads the system was designed for.

240-Pin DIMM Form Factor and Major-Brand Chips

The 240-pin DDR3 layout drops straight into the four available slots on the rp5800 motherboard. Major-brand chipsets underpin the modules, and the lack of a heat spreader keeps the profile low for tight chassis clearance. Unbuffered, single-rank organisation simplifies installation without BIOS tuning.

Upgrade Path to 32 GB Maximum

The board supports up to 32 GB across its four sockets, so this pair leaves two slots free for future expansion. Builders who need ECC error correction or registered modules must look elsewhere, as this kit is strictly non-ECC unbuffered. The jump is worthwhile when the existing configuration is below 8 GB and the workload fits standard desktop memory.

Questions about this item

What does the PC3 12800 DDR3 1600 rating mean for real-world bandwidth on the HP rp5800?

PC3 12800 is the JEDEC standard name for DDR3 1600 memory; the HP rp5800 runs these modules at 1600 MHz with CL11 timing.

Will these 240-pin DIMMs fit the four slots inside the HP rp5800 chassis?

Yes, the kit contains two 240-pin unbuffered non-ECC DIMMs; the HP rp5800 has four DDR3 DIMM sockets supporting up to 32 GB total.

What is the correct order to install the two 4 GB sticks so the HP rp5800 recognises the full 8 GB?

Populate the lowest-numbered sockets first, typically the two black slots, then power on; the system will detect both modules automatically.
