HP/Compaq DDR 266 ECC Registered kit

This 2GB kit contains two 1GB 184-pin DDR SDRAM modules rated at DDR 266 (PC 2100). Both sticks are ECC Registered and operate at 2.50V, matching the requirements of specific HP/Compaq workstations and servers that demand registered memory. The dual-channel pair is sold new and has no heat spreader.

Verify 184-pin DDR slot and registered support

Before ordering, confirm the target system uses 184-pin DDR memory slots and accepts Registered ECC modules at 2.50V. Many desktop boards only support unbuffered non-ECC memory, so the motherboard or server manual must explicitly list Registered DDR 266 compatibility. Mixing registered and unbuffered DIMMs will prevent boot.

Fits HP/Compaq systems needing registered DDR

The kit installs directly into compatible HP/Compaq platforms that require Registered ECC DDR SDRAM. It satisfies the registered buffer requirement that standard unbuffered memory cannot meet, freeing the builder from hunting for matched single modules. No additional cooling hardware is needed because the modules ship without heat spreaders.

Questions about this item

Does the kit include both 1GB modules or must I buy a second stick separately?

The kit contains two 1GB 184-Pin DDR SDRAM modules for a total of 2GB, so no extra sticks are needed.

Should I choose this DDR 266 (PC 2100) registered ECC kit or a faster unbuffered kit for my HP/Compaq system?

This kit is built as DDR 266 (PC 2100) registered ECC memory at 2.50V; only select it if your HP/Compaq system specifically requires registered ECC DDR 266 modules.

What does the DDR 266 (PC 2100) rating mean once the memory is installed in the server?

The modules run at 266 MT/s with a 2.50V supply, delivering PC 2100 bandwidth while the registered ECC design adds error correction and signal buffering for stable server operation.
