Sony Vaio compatible 4 GB DDR3 SO-DIMM

This 4 GB DDR3-1333 (PC3-10600) SO-DIMM is built to Computer Memory Solutions specification CM5126410600SODRH. It runs at 1.5 V with CL7 7-7-7 timing in a 2Rx8 unbuffered layout and carries the supplier lifetime guarantee for the listed Sony Vaio models VPCEH24FX/W, VPCEH1J1E, VPCEH1L0E and VPCEH1L8E.

Not for non-Sony platforms

The module is validated only for the four Sony Vaio models shown in the compatibility list. Systems that need ECC, registered DIMMs, a different pin count, or another DDR generation will not accept this part. Buyers whose laptop is not one of those four models must select memory qualified for their own platform.

CL7 7-7-7 timing at DDR3-1333

The CAS latency 7 and 7-7-7 cycle timing are the decisive specification for these Vaio chipsets. Memory rated at looser timings may not train correctly, so matching CL7 is the single parameter that determines whether this upgrade will post and run stably.

Questions about this item

What does the PC3-10600 rating mean for actual bandwidth inside the laptop?

PC3-10600 indicates a peak transfer rate of 10600 MB/s when the module runs at 1333 MHz.

The listing shows both DDR3-1333 and DDR3-1600; which speed will the Sony Vaio actually use?

The Sony Vaio VPCEH series memory controller supports up to 1333 MHz, so the module will operate at DDR3-1333.

Will this 204-pin SO-DIMM fit the two memory sockets in the VPCEH chassis?

Yes, the 204-pin DDR3 SO-DIMM form factor matches the two SODIMM slots in the Sony Vaio VPCEH models listed.
