4GB DDR3 1600 Desktop Memory

This A-Tech module provides 4GB of DDR3 1600 memory in a single 240-pin DIMM package. It is built as a compatible replacement for specific Crucial part numbers including BLS4G3D169DS1J and BLT4G3D1608DT2TXRG. The kit targets desktop users who need a straightforward capacity upgrade for older systems.

DDR3 1600 CL11 1.5V Standard Limits

The module operates at the standard DDR3 voltage of 1.5V with a tested frequency of 1600 MHz and a CAS latency of CL11. As an unbuffered non-ECC DIMM, it conforms to the PC3-12800 specification without error correction or registered buffering. Systems must support this exact voltage and speed profile for correct operation.

240-Pin DIMM Installation Notes

Installation requires aligning the 240-pin DIMM with the motherboard slot notch and pressing firmly until the retention clips lock. Common issues include the system failing to post if the motherboard does not support DDR3 1600 or if the slot is populated incorrectly. Verifying the supported memory specifications before purchase prevents compatibility problems.

Questions about this item

Should I pick the single 4 GB module or a kit for my upgrade?

This listing is a single 4 GB DDR3 1600 CL11 DIMM; add a second identical module if your board supports dual-channel and you need 8 GB total.

What does the 1600 MHz rating deliver in daily use?

At 1600 MHz with CL11 timing the module runs at the standard PC3-12800 data rate, giving typical desktop workloads a measurable bandwidth boost over slower DDR3.

Which interface does this DIMM use and what does it limit?

The 240-pin DDR3 DIMM interface limits the module to DDR3 signalling at 1.5 V and the PC3-12800 transfer ceiling.
