Targeted upgrade for HP 4000 Pro SFF

This kit delivers 8 GB of DDR3 memory across two 4 GB unbuffered DIMMs built specifically for the HP/Compaq Business Desktop 4000 Pro (SFF). The modules run at 1333 MHz with CL9 timings at 1.5 V and carry the CM5126410600DIMM part number. Computer Memory Solutions guarantees compatibility with the listed HP part numbers including A7H78UT and LA069UT.

Suits owners of the listed HP desktops.

Buyers who need ECC error correction or registered modules should look elsewhere because this kit is non-ECC and unbuffered. The package contains exactly two sticks, so systems with only one memory slot or a different pin layout cannot use it. Maximum supported capacity for the target machine is 8 GB, limiting further expansion.

Dual-channel pair running at 1333 MHz

The two modules are designed to be installed as a matched pair to enable dual-channel operation on the HP 4000 Pro platform. HP documentation notes the memory bus operates at 1066 MHz even when 1333 MHz modules are fitted. A 64-bit operating system is required to address the full 8 GB capacity.

Questions about this item

Will these 1333 MHz DDR3 modules run at full speed in my HP 4000 Pro SFF, or does the motherboard limit the bus to 1066 MHz?

HP documentation states the memory bus runs at 1066 MHz, so the 1333 MHz modules will operate at that lower speed.

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

Enter the BIOS or use a system-information tool; it should report 8 GB total with dual-channel active when both modules are seated in the paired slots.

Does the package include only the two 4 GB DIMMs, or are any tools or cables supplied?

The box contains two 240-pin DDR3 memory sticks and nothing else; no tools, cables or brackets are included.
