8GB DDR3 1066 kit for desktops

This kit provides eight gigabytes of DDR3 memory in four matched 2GB modules. It targets owners of older desktop PCs or workstations that use the PC3-8500 standard and need a straightforward capacity increase.

JEDEC standard unbuffered DIMMs

Each module is a 240-pin non-ECC UDIMM running at 1.5 volts with CL7 latency. The black circuit boards have no heat spreader, so they fit in tight slots and work with standard CPU coolers without clearance issues.

Check motherboard DDR3 support and slot count

Verify that your board accepts DDR3 1066 unbuffered memory and has four available DIMM sockets for the full kit. Confirm the maximum supported capacity per slot and total system limit before ordering.

Questions about this item

Does the DDR3 1066 PC3-8500 interface cap the kit at 1066 MHz in practice?

Yes, the JEDEC-standard DDR3 1066 PC3-8500 rating means each module runs at 1066 MHz with CL7 timings at 1.5 V, and the memory controller will not exceed that speed without manual overclocking.

What physical slot and clearance does the 240-pin UDIMM kit require?

Each 2 GB stick uses a standard 240-pin DDR3 UDIMM form factor without a heat spreader, so it fits any desktop DDR3 DIMM slot and clears most CPU coolers.

How is the four-module kit installed, and what step do builders often miss?

Power down, open the case, align each 240-pin module with the keyed slot and press firmly until the retention clips click; the step many miss is populating the correct colour-coded channel pairs so the board runs in dual-channel mode.
