Kingston 512MB PC2100 DDR DIMM

This Kingston 512MB PC2100 DDR module is desktop memory built to the 184-pin DIMM form factor. It runs at 266MHz with a CAS latency of 2.5 and is sold in new condition. The module is non-ECC and unbuffered, matching the PC2100 standard for older desktop platforms.

Suits legacy desktop upgrades

This module suits owners of desktops that accept 184-pin DDR DIMMs at 266MHz and need a single 512MB stick. Builders who need higher capacity per slot, ECC error correction, registered buffering, or a different pin count should look at other parts.

184-pin DDR 266MHz interface

The 184-pin DDR interface at 266MHz is the specification that decides fitment; the motherboard must support this exact pin layout and speed. If the board requires a different pin count or memory generation, this module will not install or function.

Questions about this item

What does the 266 MHz rating mean for my system?

The module runs at 266 MHz DDR, giving a peak bandwidth of PC2100 when installed in a compatible motherboard.

How does the 184-pin DDR interface limit performance?

The 184-pin DDR interface caps the data rate at 266 MHz, so the module cannot exceed PC2100 speeds even if the board supports faster memory.

Will the 184-pin DIMM fit my desktop motherboard?

Yes, the 184-pin DIMM fits standard DDR desktop memory slots that accept unbuffered, non-ECC modules.
