A-Tech 4GB DDR3 1600 DIMM

This A-Tech module is a 4GB DDR3 1600 desktop DIMM built for system memory upgrades. It runs at the standard 1.50V with CL11 timing and uses unbuffered, non-ECC architecture. The 240-pin form factor fits mainstream desktop motherboards that support DDR3. Major brand chips are used throughout for consistent reliability.

Suitable for compatible HP desktops

The part matches HP numbers 655410-150, 655410-571, B1S53AA and B4U36AA, making it a direct replacement for those configurations. It also works in AMD and Intel platforms that accept DDR3 1600 unbuffered DIMMs. Systems requiring ECC, registered modules, or a different DDR generation cannot use this memory.

The deciding specification is DDR3 1600 unbuffered

Your motherboard must support DDR3 at 1600 MT/s (PC3-12800) with 1.50V unbuffered DIMMs. If the board calls for ECC, registered, or a different voltage or generation, this module will not be compatible. Always verify the supported memory specification before ordering.

Questions about this item

Will this module fit a motherboard that needs a 240-pin DDR3 DIMM?

Yes, the module is a 240-pin DDR3 DIMM, the standard form factor for desktop DDR3 memory slots.

Does the 1.5 V operating voltage match the standard DDR3 specification?

Yes, 1.5 V is the standard DDR3 voltage, so it will work with any desktop board that follows the DDR3 specification.

Can I use this stick alongside an existing CL11 DDR3-1600 module?

Yes, matching the 1600 MHz speed and CL11 latency allows the two modules to run together at their rated settings.
