HP 4000 Pro compatible DDR3 upgrade

This single 2GB DDR3 module is built specifically for the HP 4000 Pro desktop. It runs at 1066MHz with CL7 latency and 1.5V operation. The unbuffered, non-ECC UDIMM format matches the original system requirements exactly.

JEDEC and RoHS compliant module

The memory meets JEDEC standard specifications and RoHS environmental requirements. This compliance ensures a warranty-safe upgrade that will not void the original system coverage. Every module is tested in-house to verify reliability before it ships.

Standard 240-pin UDIMM form factor

The 240-pin DIMM design fits directly into the desktop memory slots without adapters. No heat spreader is included, keeping the profile low for tight chassis clearances. Installation follows the usual desktop DIMM procedure and requires no special tools.

Questions about this item

Will the 240-pin DDR3 module require any periodic cleaning or component replacement?

No, the UDIMM has no moving parts or heat spreader, so it needs no scheduled maintenance once installed in the HP 4000 Pro.

What limit appears first when the 1066 MHz CL7 DIMM runs continuously at full load?

The memory controller's maximum supported bandwidth caps throughput before the module itself reaches any thermal or electrical ceiling.

How much heat and power does the 1.5 V Non-ECC stick produce during all-day operation?

At 1.5 V the module draws only a few watts and runs cool enough that no active cooling is required inside the workstation chassis.
