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.
