Compatible DDR2 upgrade for Satellite A135

This 1GB DDR2 533MHz SODIMM module is built to match the memory specification of Toshiba Satellite A135 series notebooks. It arrives as a single 200-pin unbuffered stick with CL4 timing and 1.8V operation, ready to install in an empty slot.

Who should buy this and who should not

Owners of any listed Satellite A135 model needing a straightforward capacity increase can use this module. Buyers whose laptop requires more than 1GB per slot, or who need ECC or registered memory, should look elsewhere.

The spec that confirms fit

The decisive figure is the DDR2 533 (PC2 4200) speed rating combined with the 200-pin SODIMM form factor; only systems designed for that exact combination will accept the module.

Questions about this item

How much power does the 1.8 V DDR2 module draw when the laptop runs all day?

The SODIMM operates at 1.8 V with no heat spreader, so it adds only a small load to the Satellite A135 power budget during continuous use.

Does my Toshiba Satellite A135 need a free 200-pin SODIMM slot to install this stick?

Yes, the upgrade requires an open 200-pin DDR2 SO-DIMM socket; the A135 series provides two such slots for memory expansion.

Will this PC2-4200 module work alongside the original 533 MHz memory already in my A135?

It matches the factory 533 MHz speed and CL4 timing, so it will run in step with the existing DDR2 module without down-clocking.
