Compatible 4 GB DDR3 Kit

This two-module kit provides 4 GB of DDR3 memory rated at 1600 MHz with CL11 timing. It is built specifically for the HP Compaq Pro 6305 Small Form Factor Business PC. The unbuffered, non-ECC DIMMs operate at 1.5 V and use major-brand components.

Verify System Requirements

Confirm that your Pro 6305 SFF has free 240-pin DIMM slots before ordering. The platform supports a maximum of 32 GB across four sockets. These modules are validated for the listed part numbers including C1E17UT and the E2A and E3S series units.

Build Integration

The pair installs directly into the standard DDR3 slots without a heat spreader, keeping height low for the compact chassis. Adding this matched kit leaves two sockets open for future expansion up to the 32 GB limit. No extra cables or cooling are required.

Questions about this item

What comes in the box with the CM2566412800DIMMSR kit and is anything else needed for installation?

The package contains two 2 GB DDR3 1600 DIMM modules; no extra parts are required to install them in the HP Compaq Pro 6305 Small Form Factor Business PC.

Should I choose the 4 GB (2 x 2 GB) CL11 kit or a different capacity for the HP Compaq Pro 6305 SFF?

This 4 GB kit uses two of the four available slots and the system supports up to 32 GB total, so you can add another identical kit later if more memory is needed.

What does the DDR3 1600 PC3 12800 rating mean for real-world performance in the Pro 6305?

The modules run at 1600 MHz with CL11 11-11-11 timing at 1.5 V, delivering the standard PC3 12800 bandwidth the Pro 6305 memory controller expects.
