A-Tech 8GB DDR3L ECC UDIMM

This 8GB DDR3L module runs at 1600MHz with CL11 latency and 1.35V operation. It uses unbuffered ECC chips in a 2Rx8 configuration on a 240-pin DIMM. The stick is built for servers and workstations that require error-correcting memory.

Fits HP part numbers including 713752-081

The module plugs into a standard DDR3 DIMM slot on a compatible motherboard. It frees a second slot for another 8GB stick if the board supports two channels. No registered buffer is present so the memory controller must accept unbuffered ECC UDIMMs.

Sustained load stability with ECC correction

Error-correcting code detects and corrects single-bit errors during continuous operation. The low 1.35V voltage reduces heat output during long compute runs. CL11 timing delivers consistent latency without the variability seen in overclocked modules.

Questions about this item

Will the DDR3L 1600MHz speed and CL11 latency limit throughput during sustained server workloads?

The module runs at DDR3L 1600 (PC3L-12800) with CL11 latency; sustained throughput is capped by that 1600 MT/s data rate and the unbuffered 2Rx8 organisation.

How much heat and power does the 1.35V DDR3L module produce when running continuously in a server?

Operating at 1.35 V low voltage, the unbuffered ECC UDIMM draws less power and generates less heat than standard 1.5 V DDR3, easing cooling in 24/7 operation.

Does my motherboard need a 240-pin DDR3L slot that supports unbuffered ECC UDIMM 2Rx8 modules?

Yes — the DIMM is a 240-pin DDR3L 1.35 V unbuffered ECC UDIMM with 2Rx8 organisation; the board must accept that exact form factor, voltage and ECC type.
