| Description: | Buy HPE 627812-B21 16GB DDR3 Memory Kit. Genuine part with fast worldwide shipping from Euroland IT Store UK. |
| Availability: | In Stock |
The HPE 627812-B21 is a 16GB registered DDR3 memory kit built for HPE ProLiant G7 servers. It holds a single 16GB module, so one kit fills one DIMM slot. The module is a dual rank x4 PC3L-10600R RDIMM running at DDR3-1333 with CAS latency 9 and error correcting code (ECC).
This kit suits IT teams who still run G7 rack and blade servers and need to add memory, replace a failed DIMM or match the modules already fitted. Because it is a low voltage part rated at 1.35V, it can also help reduce power draw across a fully populated server.
You can order this G7 memory kit from Euroland IT Store as a New or Refurbished unit, depending on what we hold in stock at the time.

627812-B21 is the option kit number. HPE uses option numbers for the boxed upgrade product that a reseller sells to a customer. The same memory module also carries a spare part number for service replacement and an assembly number printed on the module label. All three point to the same 16GB 2Rx4 low voltage RDIMM.
The exact number matters with server memory. Two 16GB DDR3 modules can look alike yet differ in rank count, voltage, speed or buffering. A G7 server will only behave as expected when the DIMMs follow the supported list for that platform. Buying by option number, spare number or assembly number removes most of the guesswork.
Standard DDR3 runs at 1.5V. The PC3L marking on this module shows it is a low voltage part designed to run at 1.35V. On a server with 12 or 18 DIMM slots per processor pair, that small saving per module adds up across the whole chassis and lowers heat inside the case.
Low voltage operation depends on the server and how many DIMMs sit on each channel. When the memory population is heavy, the system BIOS may run the modules at 1.5V instead to keep the configuration stable. That behaviour is normal. If low power is a priority, check the memory population guidance in the user guide for your exact server before planning a full upgrade.
Being registered, the module has a register chip that buffers the address and command signals. This lets each memory channel carry more modules than unbuffered memory would allow, which is why RDIMMs became the standard choice for dual processor G7 systems.
A New 627812-B21 suits buyers who want a module that has not been in service before, for example when building a matched set for a fresh deployment or when an internal policy calls for new components. Please check the product page for the condition description and warranty that apply to the unit you order.
A Refurbished 627812-B21 is a cost-effective way to keep an older G7 estate running. It is a good fit when you need to replace one failed DIMM, extend an existing memory bank or keep spares on the shelf. The product page shows the condition and warranty details for refurbished stock.
This memory kit is listed for the following HPE ProLiant G7 servers:
Before you order, read the label on a DIMM already fitted in the server and confirm the server model and generation. Gen8 and later servers use different memory lists, so a G7 module should not be assumed to fit a newer platform.
You can browse more modules in our server memory kit category.
When adding memory to a dual processor G7 server, spread the new modules evenly across both processors. Each processor controls its own memory channels, and an unbalanced layout can leave one CPU short of local memory. Fitting DIMMs in identical sets per channel also keeps the memory controller running in its best mode. If the server shows a memory error after an upgrade, reseat the modules and check the Integrated Management Log for the slot number.
Euroland IT Store supplies businesses, IT teams, resellers and repair shops across the UK with server memory and spare parts. The product page shows the current condition, warranty, stock and delivery details. Orders over £100 + VAT ship free to the UK mainland. If you are not sure this kit is right, contact our team with your server model and the part number on your existing DIMM, or call our sales line on 0203 209 6002.
It is listed for ProLiant G7 servers including the DL360 G7, DL380 G7, DL580 G7, BL460c G7 and BL620c G7, so check your server model and an existing DIMM label before you order.
New suits fresh builds or strict purchasing policies, while Refurbished is a lower cost way to replace a failed DIMM or extend an existing G7 memory bank.
Warranty depends on the condition you choose, and the exact terms are shown on the product page for each option.
Yes, we deliver across the UK, and orders over £100 + VAT qualify for free UK mainland shipping, with delivery details shown on the product page.
Yes, it is a low voltage module rated at 1.35V, and some servers run low voltage DIMMs at 1.5V when the memory population requires it.
