DESCRIPTION

This document describes Kingston’s 128M x 64-bit 1GB

(1024MB) DDR2-800 CL5 SDRAM (Synchronous DRAM)

memory module, based on sixteen 64M x 8-bit DDR2 FBGA

components. This module has been tested to run at DDR2

800MHz at low latency timing of 5-5-5-15 at 2.0V. The SPD

is programmed to JEDEC standard latency 667Mhz timing

of 5-5-5-15 at 1.8V. This 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: 5-5-5-15 at +1.8V / 5-5-5-15 at +2.0V

• 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.
