Memory Module Specification
KHX5400D2/1G
1GB 128M x 64-Bit PC2-5400
CL4 240-Pin DIMM
DESCRIPTION:
This document describes Kingston's 128M x 64-bit 1GB (1024MB) DDR2-675 CL4 SDRAM (Syn-
chronous DRAM) memory module, based on sixteen 64M x 8-bit DDR2 FBGA components. This
module has been tested to run at DDR2 675MHz at low latency timing of 4-4-4-10 at 1.85V. The SPD
is programmed to JEDEC standard latency DDR2 667MHz timing of 4-4-4-12 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 4 (clock)
Burst Length: 4, 8 (Interleave/nibble sequential)
Programmable Burst type (sequential & interleave)
Timing Reference: 4-4-4-10 at +1.85V / 4-4-4-12 at +1.8V
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.
