512MB DDR 266 ECC module

This 512MB DDR 266 (PC 2100) module carries ECC and an unbuffered design for systems that require error correction without registered signalling. It suits legacy servers or workstations built around the PC 2100 standard.

ECC unbuffered operation

The ECC function detects and corrects single-bit errors, improving data integrity for always-on workloads. Because the module is unbuffered, it plugs directly into boards wired for unbuffered DIMMs and cannot be mixed with registered memory.

2.50V 184-pin DIMM build

Gold contacts and a standard 184-pin DDR form factor allow straightforward insertion into matching slots. The 2.50V operating voltage matches the DDR 266 specification, so the module works with boards designed for that voltage level.

Otázky k tomuto produktu

Will the CL2.5 timing on this 512MB DDR 266 module ever need adjustment or replacement?

The CAS latency is fixed at CL2.5 by the module's SPD profile; no timing adjustments are required and the memory itself has no moving parts to wear out.

What limit appears first when this ECC unbuffered stick runs at 266 MHz continuously?

Sustained operation is bounded by the 2.50 V supply and the DDR 266 (PC 2100) data rate; the memory controller reaches its throughput ceiling before the module overheats.

How much heat and power does this 2.50 V ValueRAM DIMM produce during all-day server use?

At 2.50 V the module draws only the current needed for DDR 266 transfers, generating modest warmth that standard server airflow handles without extra cooling.
