4GB DDR2 1066MHz Kit

This Simmtec desktop memory kit provides 4GB total capacity across two 2GB DIMMs. It is built for systems that use DDR2 technology and need a matched pair for dual-channel operation. The modules suit older workstations or upgrades where DDR2 slots are still in use.

240-PIN DDR2 Interface Limits

The kit runs at 1066MHz under the PC2-8500 standard using 240-pin DIMM connectors. DDR2 platforms cap bandwidth below later DDR generations and do not support higher densities per slot. Mixed speeds will force all modules to the slowest rated frequency.

Pre-Installation Checks

Confirm your motherboard accepts DDR2 DIMMs and has two free 240-pin slots for the paired modules. Verify the board supports 1066MHz operation or will downclock automatically. Ensure the BIOS recognises 2GB per slot density before ordering.

Questions about this item

Should I pick the 4GB kit with two 2GB sticks or a single 4GB module?

This kit supplies two 2GB DIMMs so the board can run in dual-channel mode; a single 4GB stick would leave the second channel empty and cut peak bandwidth.

What does the 1066MHz rating deliver once the modules are installed?

The memory bus runs at 1066MHz, giving a theoretical peak transfer rate of 8500MB/s per channel when the motherboard supports that speed.

How does the PC2-8500 designation relate to the 240-pin DDR2 interface?

PC2-8500 is the bandwidth label for DDR2-1066 on the 240-pin DIMM form factor, capping the module at 8500MB/s in standard operation.
