DESCRIPTION
This document describes ValueRAM’s 256M x 64-bit 2GB
(2048MB) PC2-4200 CL3 SDRAM (Synchronous DRAM)
memory module. The module is based on sixteen 128M x
8-bit DDR2 FBGA components. The SPDs are programmed
to JEDEC low latency timing of 3-3-3-8 at 1.8V. This 200-pin
SODIMM uses gold contact ngers and requires +1.8V. The
electrical and mechanical specications are as follows:
Storage Temperature -55° C to +125° C
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, 4, 3 (clock)
• Burst Length: 4, 8 (Interleave/nibble sequential)
• Programmable Burst type (sequential & interleave)
• Timing Reference: 3-3-3-8 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
• PCB : Height 1.180” (30.00mm), double sided component

All Kingston products are tested to meet our published specications. Some motherboards or system congurations 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.
