12GB DDR3 1066 Desktop Kit

This Axiom NP331AV-AX kit supplies 12GB of DDR3 1066 desktop memory across six 2GB DIMMs. It uses the PC3 8500 standard and 240-pin unbuffered non-ECC modules. The kit is designed for systems that accept this specific speed and density.

Suits HP Pavilion Elite m9650f upgrades

The modules are validated for the HP Pavilion Elite m9650f desktop. Builders restoring or expanding that exact model can install all six DIMMs for the full 12GB capacity. Systems requiring ECC error correction, registered signal processing, or a different DDR generation will not accept these sticks.

Speed and density lock-in

The decisive specification is the DDR3 1066 (PC3 8500) rating combined with six 2GB unbuffered DIMMs. A motherboard must support this exact speed, 2GB per slot density, and 240-pin non-ECC operation for the kit to function.

Questions about this item

What comes in the Axiom NP331AV-AX 12GB kit and is anything else required?

The kit contains six 2 GB unbuffered DDR3 DIMMs for a total of 12 GB. No extra components are needed; install the modules into compatible 240-pin desktop slots.

How do I decide between the 1066 MHz and 8500 designations for this memory?

Both figures describe the same modules: DDR3-1066 is the clock rate and PC3-8500 is the matching bandwidth rating. Choose this kit when your system specifies either value.

What does the 1066 MHz rating mean once the RAM is installed in a PC?

The modules will run at 1066 MHz, delivering PC3-8500 bandwidth on a 240-pin DIMM interface, provided the motherboard supports that speed.
