16 GB DDR3-1333 ECC RDIMM kit

This 16 GB kit contains two 8 GB DDR3 1333 CL9 registered DIMMs built for HP ProLiant blade servers. The modules run at 1.5 V and include ECC error correction for data integrity in mission-critical workloads. They are validated for the BL280c G6, BL2x220c G6, BL2x220c G7, BL460c G6 and BL490c G6 platforms. The 240-pin form factor matches the server memory slots exactly.

Not for desktops or unbuffered slots

This memory will not work in standard desktop PCs, workstations that require unbuffered DIMMs, or any system that cannot accept registered ECC modules. Mixing these sticks with unbuffered memory is not supported and will prevent boot. Buyers needing non-ECC or consumer-speed RAM should look for a different product line altogether.

Registered ECC with 2Rx4 organisation

The registered buffer and 2Rx4 rank layout are the decisive factors for compatibility with the listed ProLiant blades. If your server requires registered ECC DDR3 at 1333 MT/s with this rank configuration, the kit fits; otherwise it will not post.

Questions about this item

How much power does the 1.5V DDR3 1333 RDIMM kit draw when the server runs continuously?

Each module operates at 1.5 volts, the standard for DDR3 1333 registered DIMMs, so total power scales with the number of populated slots in your ProLiant chassis.

Which HP ProLiant blade models must I already own for this 240-pin ECC registered kit to work?

The kit is validated for HP ProLiant BL280c G6, BL2x220c G6, BL2x220c G7, BL460c G6 and BL490c G6 blades; other systems are not supported.

Can I add these CL9 2Rx4 modules alongside the original HP 500662B21 or 593913B21 DIMMs already in my BL460c G6?

Yes, they replace HP part numbers 500662B21 and 593913B21, but all installed DIMMs must be ECC registered — mixing with unbuffered memory will prevent boot.
