512 MB Registered DDR 266 Server Memory

This module delivers 512 MB of DDR 266 (PC 2100) capacity on a 184-pin DIMM. It operates at CL2.5 latency with 2.50 V and includes ECC error correction plus registered buffering for signal integrity. The stick is designed for legacy server platforms that require registered ECC memory.

Suited for legacy registered ECC DDR systems

Administrators maintaining older servers that specify registered ECC DDR 266 modules can use this part directly. It is not for systems that require unbuffered memory, higher density per slot, or platforms that do not support registered signalling.

Registered ECC buffering decides compatibility

The registered buffer and ECC function are mandatory for the target motherboards; boards without registered support will not accept this DIMM. Verify the platform demands registered ECC DDR 266 before purchase.

Questions about this item

Does my server motherboard need 184-pin DDR slots to accept this KVR266X72RC25/512 module?

Yes, this is an 184-pin DDR SDRAM DIMM and requires a matching 184-pin DDR socket on the motherboard.

Can I run this registered ECC DDR 266 stick together with unbuffered non-ECC DDR 266 modules I already have?

No, registered ECC modules must not be mixed with unbuffered non-ECC memory; the motherboard will not initialise correctly.

After installation, how can I confirm the module is running at DDR 266 with CL2.5 timings?

Enter the BIOS or use a system information tool; the memory speed should read DDR 266 (PC 2100) and CAS latency CL2.5.
