Direct Elpida Replacement

This 4GB DDR3 SO-DIMM module matches the Elpida EBJ40UG8BBU0-GN-F specification exactly. It targets laptop owners who need a verified drop-in part to restore or expand memory capacity without compatibility guesswork.

204-Pin DDR3 Slot Required

The stick fits a single DDR3 SO-DIMM socket and draws 1.5V standard voltage. It leaves any second slot free for an additional module and requires no heat spreader clearance or BIOS voltage adjustment.

CL11 Latency at 1600MHz

Rated DDR3 1600 with CAS latency 11, the module sustains its rated timing during extended multitasking sessions. Non-ECC unbuffered operation keeps the signal path simple for consistent throughput under continuous load.

Questions about this item

What is the CAS latency that limits sustained throughput?

The module runs at CL11, so each access cycle adds 11 clock delays before data moves.

How much heat and power does a 1.5 V DDR3 SO-DIMM produce under all-day load?

At the standard 1.5 V the stick draws minimal power and runs cool without a heat spreader.

Which slot type must the laptop already provide for this 204-pin module?

The system needs a DDR3 SO-DIMM socket that accepts 204-pin unbuffered non-ECC memory.
