OWC 2GB DDR3 1600 Upgrade

This 2GB DDR3 1600 PC3-12800 CL11 DIMM is built for HP 100B, 6300 Pro SFF and 6300 Pro Tower systems. It suits owners of those desktops who want a straightforward memory increase. Buyers needing ECC error correction or registered modules should look elsewhere.

Installation notes

The 240-pin unbuffered module fits standard DDR3 desktop slots and requires no special tools. Alignment is key; forcing the module can damage the slot or the gold contacts. Static discharge is the most common cause of failure, so ground yourself before handling. Systems that only accept registered or ECC memory will not work with this stick.

Pre-order checks

Confirm your motherboard uses 240-pin DDR3 slots and supports 1.5V non-ECC unbuffered memory. Verify the maximum capacity per slot and the total number of available slots in your specific HP model. Check whether the BIOS requires matched pairs for dual-channel operation before buying a single module.
