Simmtec, Inc 12GB (3×4GB) DDR2 DIMM 240-pin 667MHz PC2-5300/5400

12 GB DDR2 Kit for Legacy Desktops

This kit supplies 12 GB of DDR2 memory across three 4 GB DIMMs. It uses the 240-pin form factor and runs at 667 MHz with PC2-5300 and PC2-5400 ratings. The modules are intended for older desktop platforms that accept this generation of memory.

Suits restorations needing maximum DDR2 capacity

The three-module layout fills three slots to reach 12 GB total, which matches the upper limit of many vintage boards. Each stick is tested before shipment to reduce the risk of errors. Builders who require more than 12 GB, a different pin count, or a newer memory technology should look at other products.

667 MHz speed grade

The 667 MHz clock determines the peak data rate the kit can deliver. Systems that only support lower DDR2 speeds will still run the modules, but at the slower rate. Verify that the motherboard accepts PC2-5300 or PC2-5400 modules before purchase.
