KHX8500D2K2/2GN

2GB (1GB 128M x 64-Bit x 2 pcs.)

PC2-8500 CL5 240-Pin DIMM Kit

DESCRIPTION:

Kingston's KHX8500D2K2/2GN is a kit of two 128M x 64-bit 1GB (1024MB) DDR2-1066 CL5
SDRAM (Synchronous DRAM) "NVIDIA SLI-Ready" memory modules, based on sixteen 64M x
8-bit DDR2 FBGA components per module. Total kit capacity is 2GB (2048MB). 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 5-5-5-18 at 1.8V. Each 240-pin DIMM
uses gold contact fingers and requires +1.8V. The electrical and mechanical specifications are as
follows:

FEATURES:

Power supply : Vdd: 1.8V ± 0.1V, Vddq: 1.8V ± 0.1V
Double-data-rate architecture; two data transfers per clock cycle
Bidirectional data strobe(DQS)
Differential clock inputs(CK and CK)
DLL aligns DQ and DQS transition with CK transition
Programmable Read latency 5 (clock)
Burst Length: 4, 8 (Interleave/nibble sequential)
Programmable Burst type (sequential & interleave)
Timing Reference: 5-5-5-18 at +1.8V / 5-5-5-15 at +2.2V
Edge aligned data output, center aligned data input
Auto & Self refresh, 7.8us refresh interval (8K/64ms refresh)
Serial presence detect with EEPROM
High Performance Heat Spreader
PCB : Height 1.180” (30.00mm), double sided component

All Kingston products are tested to meet our published specifications. Some motherboards or system configurations may not
operate at the published HyperX memory speeds and timing settings. Kingston does not recommend that any user attempt to
run their computers faster than the published speed. Overclocking or modifying your system timing may result in damage to
computer components.
