OWC 4GB DDR3L ECC UDIMM

This 4GB DDR3L module runs at 1600MHz with CL11 latency and 1.35V operation. It uses a 240-pin unbuffered UDIMM form factor with ECC error correction. The 2Rx8 rank configuration meets JEDEC and RoHS standards for desktop, workstation and server platforms.

For Supermicro A1SA7 and A1SAM boards

The memory is validated for Supermicro motherboards including A1SA7-2750F, A1SAM-2550F, A1SAM-2750F, A1SRM-2558F and A1SRM-2758F. Builders needing non-ECC modules or higher densities should look elsewhere. Systems requiring registered DIMMs or different pin counts are not compatible.

Single 4GB stick with ECC headroom

One module adds 4GB of error-correcting capacity to supported Supermicro platforms. It handles typical desktop and light server workloads within the single-slot limit. Larger datasets or multi-channel configurations will require additional modules beyond this single unit.

Questions about this item

Which motherboard must I already have for this module to fit?

This 240-pin DDR3L ECC UDIMM is validated for Supermicro boards A1SA7-2750F, A1SAM-2550F, A1SAM-2750F, A1SRM-2558F and A1SRM-2758F.

Can I mix this 1.35 V DDR3L stick with older 1.5 V DDR3 modules?

The motherboard will run all installed DIMMs at the lowest common voltage, so 1.5 V modules will drop to 1.35 V if the platform supports DDR3L.

How do I confirm the stick is running at its rated 1600 MHz and CL11 after installation?

Open the BIOS or a system-information utility; the memory summary should report 1600 MHz, CL11 timing and ECC active.
