4GB DDR3 1066MHz desktop module

This 4GB DDR3 DIMM runs at 1066MHz with a CL7 latency and standard 1.5V operation. It is built for desktop systems that accept unbuffered non-ECC memory. The single-module design suits a straightforward capacity increase.

240-pin unbuffered DIMM for AMD and Intel platforms

The module fits a standard 240-pin DDR3 slot and requires no registered or ECC support from the motherboard. It is listed as compatible with both AMD and Intel desktop chipsets. Verifying the board's qualified vendor list before installation ensures proper operation.

Tested replacement for Kingston KVR1066D3N7/4G

Each stick undergoes quality-assurance testing to meet the stated 1066MHz PC3-8500 specification. The kit serves as a direct drop-in alternative for the listed Kingston part numbers. Lifetime warranty and US-based technical support are included with the purchase.

Questions about this item

Will the 1.50V voltage cause instability during long sessions?

The module runs at the standard 1.50V for DDR3, so sustained operation stays within normal thermal limits for desktop DIMMs.

How much heat or noise does this 4GB stick add when the PC runs all day?

As a passive 240-pin DIMM it produces no noise and only minimal heat; system airflow handles the small thermal load.

What must my motherboard already support for this RAM to work?

Your board needs a DDR3 1066 MHz (PC3-8500) unbuffered non-ECC DIMM slot and a memory controller that accepts 1.50V modules.
