Kingston HyperX 4GB 1066MHz DDR2 Non-ECC CL5 DIMM (Kit of 2) Desktop Memory

Hyper X 4GB PC2-8500 1066MHz DDR2 Non-ECC CL5 (5-5-5-15) DIMM (Kit of 2). Standard 256M X 64 Non-ECC 1066MHz 240-pin Unbuffered DIMMs (SDRAM-DDR2, 2.2V, CL5, Gold). KHX8500D2K2/4G is a kit of two 256M x 64-bit 2GB (2048MB) DDR2-1066 CL5 SDRAM (Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR2 FBGA components per module. Total kit capacity is 4GB (4096MB). Each module pair has been tested to run at DDR2-1066MHz at a latency timing of 5-5-5-15 at 2.2V. The SPD is programmed to JEDEC standard latency 800Mhz timing of 5-5-5-15 at 1.8V. This 240-pin DIMM uses gold contact fingers and requires +1.8V.
