OWC 8GB DDR3 1866 ECC Unbuffered UDIMM desktop RAM

SKU CH-VV2Q-SFEQJ

Single 8GB DDR3 1866 CL13 ECC unbuffered UDIMM for desktop, workstation or server upgrades

  • Capacity8GB
  • SpeedDDR3 1866 (PC3 14900)
  • CAS LatencyCL13
  • Voltage1.5V
  • ECCYes
  • Buffered/RegisteredUnbuffered

Capacity 8GB

  • ECC protection guards data integrity in workstations and servers
  • DDR3 1866 speed with CL13 latency lifts system responsiveness
  • JEDEC and RoHS compliance ensures a warranty-safe upgrade
  • Single 8 GB unbuffered UDIMM fits 240-pin desktop slots
  • 5 V operation matches standard DDR3 platform requirements

Capacity and role

This single 8GB DDR3 module runs at 1866 MHz with a CAS latency of 13. It targets desktops, workstations and NAS systems that require error-correcting code memory for data integrity.

Sustained-load behaviour

ECC circuitry detects and corrects single-bit errors during continuous operation, preventing silent data corruption in long-running workloads. The 1.5V JEDEC-standard voltage keeps power draw predictable across extended sessions.

Installation notes

The 240-pin UDIMM fits standard DDR3 slots and requires no heat spreader clearance. Most failures come from mixing registered and unbuffered modules or populating slots in the wrong order for the platform.

Questions about this item

Will this module work in a desktop that requires non-ECC memory?

No, this is an ECC unbuffered DIMM and is only compatible with systems that specifically support ECC memory.

Does the 1.5 V rating match standard DDR3 desktop slots?

Yes, 1.5 V is the standard voltage for DDR3 desktop DIMMs, so it will fit electrically into any DDR3 240-pin slot that accepts ECC modules.

What does the CL13 timing mean for real-world use?

CL13 indicates a CAS latency of 13 cycles at 1866 MHz, which is the standard JEDEC timing for this speed grade and provides typical DDR3 responsiveness.
