1GB DDR 266 ECC Unbuffered Server RAM

This 1GB DDR 266 (PC 2100) module delivers ECC error correction for data integrity in legacy server platforms. It uses a 184-pin DIMM form factor and operates at 2.50V with a CAS latency of CL2.5. The unbuffered design suits compatible motherboards that do not require registered memory. No heat spreader is included on this stick.

Ideal for maintaining older systems

IT teams restoring or expanding DDR 266-era servers will find this capacity and speed match original specifications. Workstations needing registered or buffered modules cannot use this unbuffered DIMM. Builders targeting higher capacities or faster DDR generations must source different memory technology.

DDR 266 speed and ECC support

The module runs at DDR 266 (PC 2100) with ECC enabled, a combination that determines compatibility with specific legacy chipsets. Verify your motherboard accepts unbuffered ECC DDR SDRAM at this exact speed before ordering.

Questions about this item

Will this 184-Pin DDR 266 module work in a motherboard that currently runs PC 2100 memory?

Yes, the stick is DDR 266 (PC 2100) so it matches the speed and pin count of existing PC 2100 modules.

How can I confirm the ECC function is active after installing this KVR266X72C25/1G module?

Enter the server BIOS or run a memory diagnostic; both will report ECC enabled when the module is detected correctly.

Does the retail package include only the 1 GB 184-Pin DDR SDRAM stick or are extra items supplied?

Only the 1 GB 184-Pin DDR SDRAM module is included; no heat spreader, cables or brackets come in the box.
