- 240-pin DIMM fits HP ProLiant BL660c Gen8 blade server
32GB DDR3L ECC Registered DIMM
This HP 647654-081 module provides 32GB of DDR3L SDRAM at 1.35V. It runs at 1333MHz with CL9 latency and uses a 240-pin DIMM form factor. Error-correcting code and registered signal processing are built in.
Who this suits and who it does not
Suits administrators upgrading an HP ProLiant BL660c Gen8 blade server that requires registered ECC memory. Not for desktop PCs, laptops or workstations that accept only unbuffered non-ECC modules. Not for systems needing speeds above 1333MHz or voltages other than 1.35V.
Deciding specification — DDR3L 1333MHz registered
The module follows the DDR3-1333/PC3L-10600 standard with registered ECC signalling. This combination determines compatibility with the target server platform. Verify that the motherboard supports registered DDR3L DIMMs before purchase.

Questions about this item
Does my HP ProLiant BL660c Gen8 blade server need a 240-pin DDR3L slot to accept the 647654-081 module?
Yes — the 647654-081 is a 240-pin DDR3L DIMM, so the server must provide a matching DDR3L memory slot.
Can I mix this 1.35 V registered ECC DIMM with older 1.5 V DDR3 modules in the same BL660c Gen8?
No — the 647654-081 runs at 1.35 V and uses registered ECC signalling; mixing voltages or buffering types will prevent the server from posting.
After installation, how do I confirm the 32 GB module is running at 1333 MHz with CL9 timings?
Check the BIOS memory information or run a tool such as dmidecode; it should report 32 GB, DDR3L-1333, CL9, registered ECC.
