HP 8 GB DDR3-1866 Registered DIMM

This HP 708639-B21 module provides 8 GB of DDR3 server memory in a single registered DIMM. It operates at 1866 MHz with a CAS latency of 13 and conforms to the PC3-14900R standard. The dual-rank x4 organisation supports higher density configurations on compatible platforms. The component is supplied in new condition.

Suits servers needing registered ECC memory

This module fits systems that require registered DDR3 DIMMs with PC3-14900R timing. It is not intended for desktop or laptop platforms that accept only unbuffered memory. Buyers who need non-ECC unbuffered modules or different speed grades should verify their platform requirements before purchase.

Highlights

  • 8 GB capacity for memory-intensive workloads
  • 1866 MHz DDR3 speed for fast data throughput
  • Registered design with CAS-13 latency for server reliability

Questions about this item

Should I pick the single 8 GB stick or a kit with multiple modules?

This item is a single 8 GB registered DIMM; add a second identical stick only if your server board has a free slot and the memory configurator approves the population order.

What does the 1866 MHz rating actually deliver in a live server?

The module runs at DDR3-1866 with CAS-13 timing, giving a PC3-14900 peak transfer rate when the platform enables that speed.
