Sony Vaio DDR3 1333 MHz SO-DIMM Kit
This 8 GB kit contains two 4 GB DDR3 1333 MHz SO-DIMM modules built to PC3-10600 specification. They run at CL7 7-7-7 timings and 1.5 V, are unbuffered and non-ECC, and use a 204-pin form factor. The kit is validated for Sony Vaio VPCZ137GX/B, VPCZ138GG/XQ and VPCZ1390X notebooks.
Suited for owners of the listed Vaio models
Buyers upgrading one of the three named Sony Vaio models can install this matched pair to reach the platform's 8 GB maximum in dual-channel mode. The modules are not compatible with systems that require ECC, registered memory, or a different DDR generation, and they will not fit desktop DIMM slots.
1333 MHz CL7 DDR3 specification
The decisive figure is the DDR3 1333 MHz (PC3-10600) speed with CL7 latency, which matches the memory controller settings of the supported Vaio models. Installing modules at a different speed or latency may prevent the system from booting or force it to run at reduced performance.

คำถามเกี่ยวกับสินค้านี้
Should I choose the 2x4GB kit or a single 8GB stick for my Sony Vaio VPCZ137GX/B?
The 2x4GB kit is required because the system has two sockets and modules must be installed in pairs for dual-channel mode, as specified for the VPCZ137GX/B, VPCZ138GG/XQ and VPCZ1390X models.
What does the DDR3-1333 CL7 rating deliver in actual use on this laptop?
The CL7 timing at 1333 MHz gives lower latency than standard CL9 modules, improving responsiveness in memory-bound tasks while running at the standard 1.5 V DDR3 voltage for the supported Sony Vaio models.
Does the 204-pin SO-DIMM interface limit the speed to PC3-10600 on these Vaio models?
Yes, the 204-pin DDR3 SO-DIMM form factor and the system's memory controller cap the transfer rate at PC3-10600 (1333 MHz), so faster DDR3 modules would simply downclock to this speed.
