OWC 4GB DDR3 for HP 4000 Pro

This single 4GB DDR3 1066 PC3-8500 CL7 module targets owners of the HP 4000 Pro desktop who need a straightforward memory increase. The 240-pin UDIMM runs at 1.5V and uses a 2Rx8 unbuffered non-ECC design. It is built to JEDEC and ROHS standards for a warranty-safe upgrade.

No extra accessories or software included

The package contains only the memory stick itself; no heat spreader, tools or installation media are supplied. OWC provides a limited lifetime warranty and free technical support, but those services are separate from the physical product. The module is tested in-house to meet OEM specifications before shipping.

DDR3 1066 limits bandwidth to PC3-8500

The DDR3 1066 interface caps theoretical throughput at PC3-8500, which restricts performance in modern multi-threaded workloads. Systems requiring ECC error correction or registered buffering cannot use this stick. Builders needing higher capacities or faster speeds must select a different memory generation.

Soalan tentang produk ini

Will the 240-pin DDR3 module need replacement if I later add more than 4GB?

The 4GB 2Rx8 DIMM occupies one slot; you can add matching DDR3 1066 modules up to the HP 4000 Pro’s maximum supported capacity without removing this one.

What limit appears first during sustained heavy workloads on this PC3-8500 CL7 stick?

The 1066 MHz data rate and CL7 latency set the throughput ceiling; the memory controller will hit that bandwidth wall before voltage or thermal limits become a factor.

How much heat or noise does the 1.5 V unbuffered DIMM produce running all day?

With no heat spreader and standard 1.5 V JEDEC operation, the module adds minimal heat and zero audible noise; system fans handle any extra warmth.
