2GB DDR3 1333 ECC for HP/Compaq

This 2GB DDR3 1333 ECC unbuffered module is built for HP and Compaq systems that require registered error correction without a buffer. It matches part number 500670-B21 and suits owners maintaining or expanding compatible workstations or servers. The dual-rank design fits the memory architecture specified by the original manufacturer.

Installing 240-pin DDR3 in matched slots

The 240-pin DIMM seats in standard DDR3 slots, but the system will only recognise the module if the platform supports ECC unbuffered memory at 1333 MHz. A common issue is mixing this stick with non-ECC or registered modules, which prevents boot or disables error correction. Install in matched channel pairs when the board requires it.

DDR3 1333 bandwidth and capacity ceiling

DDR3 1333 delivers a fixed peak transfer rate, so total throughput scales with the number of populated channels rather than higher clock speeds. The 2GB density limits the maximum addressable memory per slot, and the unbuffered ECC design restricts use to platforms that explicitly support this combination. Systems needing larger modules or faster DDR generations cannot use this part.

Questions about this item

How can I verify the KTH-PL313E/2G is running at DDR3 1333 with ECC active after installation?

Enter the system BIOS or use a tool like CPU-Z on the HP/Compaq machine; the memory tab should show 1333 MT/s and ECC enabled for the 2GB module.

What comes with the KTH-PL313E/2G and what must I source separately?

The box contains the single 2GB 240-Pin DDR3 SDRAM DIMM; no additional cables, brackets or software are required for installation in a compatible HP/Compaq system.

Which capacity of the KTH-PL313E series should I choose for a dual-rank 2GB upgrade?

Select the 2GB KTH-PL313E/2G — it is the only capacity in this MPN and provides dual-rank DDR3 1333 ECC unbuffered memory for supported HP/Compaq platforms.
