4GB DDR3 kit for HP business desktops

This 4GB kit contains two 2GB unbuffered DIMMs rated at DDR3 1333 (PC3 10600) with CL9 timing and 1.5V operation. It is built for HP and Compaq Business Desktop 4000 Pro, 500B, 505B and related series that use 240-pin DDR3 memory.

Tool-free DIMM installation in matched pairs

The modules slot into standard 240-pin DDR3 sockets without cables or screws. The system has four sockets and the manufacturer notes that modules must be added in like pairs to enable dual-channel operation; mixing capacities or speeds can prevent the expected bandwidth gain.

Check your model, OS and socket count before buying

Confirm your desktop appears in the supported list such as 4000 Pro, 500B, 505B, 6000 Pro, 6005 Pro, 6200 Pro, dx7510 or Pro 2000. A 64-bit operating system is required to address the full 4GB, and the memory bus runs at 1066MHz even with 1333MHz modules installed.

Questions about this item

How do I confirm the kit is running at 1333 MHz with CL9 timings after installation?

Open the BIOS or a system information utility and verify the memory speed reads 1333 MHz and the timings show 9-9-9; the modules operate at 1.5 V and are unbuffered non-ECC, so the firmware should detect them automatically.

What exactly is included in the package and is anything else required?

The box contains two 2 GB DDR3 240-pin DIMM sticks for a total of 4 GB; no additional cables, brackets or software are needed — just insert them into the motherboard slots.

Should I choose this 4 GB kit or add another kit to reach the 8 GB maximum?

The supported desktops accept up to 8 GB across four slots; installing two more identical 2 GB modules in the remaining slots will enable full dual-channel operation and reach the 8 GB limit.
