SK hynix HMA851S6DJR6N-XN_UA 4GB DDR4 SO-DIMM 3200MHz CL22 1.2V 260-Pin laptop memory accessory

4GB DDR4 SO-DIMM for laptop upgrades

This module delivers 4GB of DDR4 memory in a 260-pin SO-DIMM form factor. It operates at 3200MHz with a CAS latency of CL22 and runs at the standard 1.2V voltage. The non-ECC, unbuffered design suits mainstream laptop memory slots.

Sustained operation at 3200MHz PC4-25600

The single-rank 1Rx16 organisation provides consistent bandwidth for everyday multitasking and office workloads. Standard JEDEC timings ensure stable performance during extended sessions without manual tuning. Low 1.2V power draw helps maintain thermal headroom in compact chassis.

260-pin DDR4 SO-DIMM compatibility gate

This part fits only systems that accept 260-pin DDR4 SO-DIMM modules at 3200MHz. Buyers needing ECC error correction, higher capacities per slot, or different pin counts must select an alternative module.
