FAQ
What is the capacity of this memory module?
This Axiom memory module has an 8GB capacity. It uses DDR3 SDRAM technology operating at 1333 MHz with a PC3-10660 standard. The 8GB size provides substantial memory for server workloads while maintaining compatibility with HP ProLiant Gen8 systems that support this configuration.
Does this memory support ECC?
Yes, this module includes ECC (Error-Correcting Code) functionality. ECC detects and automatically corrects single-bit memory errors, which helps prevent data corruption and system crashes. This feature is particularly important for server environments where data integrity and system stability are critical requirements.
What does 'registered' mean for this RDIMM?
Registered refers to the signal processing architecture of this RDIMM. The module includes a register between the memory controller and DRAM chips that buffers address and command signals. This improves signal integrity, reduces electrical load on the memory controller, and enables support for higher memory capacities in server configurations compared to unbuffered modules.
What servers is this memory compatible with?
This RDIMM is compatible with HP ProLiant Gen8 server models including DL360p, DL380p, ML350p, BL460c, DL160, SL230s, SL270s, DL560, DL380e, ML350e, DL360e, WS460c, and BL660c. It's designed specifically for the Gen8 platform architecture and should not be used in earlier or later generation servers without verifying compatibility.
What is the form factor and pin count?
This module uses a 240-pin RDIMM (Registered DIMM) form factor. RDIMMs are specifically designed for server applications and differ from standard desktop DIMMs in their registered architecture. The 240-pin configuration matches the physical and electrical requirements of compatible HP Gen8 server memory slots.
