Crucial CT12864X335 1GB 200-Pin DDR SO-DIMM DDR 333 laptop RAM
A 1 GB DDR 333 laptop module with a 200-pin SO-DIMM form factor and CL2.5 latency
- Capacity1GB
- Type200-Pin DDR SO-DIMM
- SpeedDDR 333 (PC 2700)
- CAS LatencyCL2.5
- Voltage2.50V
- ECCNo
- 1GB capacity adds responsive multitasking headroom
- DDR 333 (PC 2700) speed matches legacy laptop specs
- CL2.5 latency tightens memory response times
- 50V operation suits original DDR platform voltage
- 200-pin SO-DIMM form factor fits compatible DDR slots
Suitable legacy upgrade
This 1 GB DDR SO-DIMM fits 200-pin laptop slots that require PC 2700 speed. It targets owners of older notebooks needing a direct memory replacement without BIOS complications.
Sustained operation profile
Unbuffered construction and 2.50 V operation keep electrical load predictable during long sessions. CL2.5 latency remains stable because the module lacks ECC overhead or registered buffering that could introduce variability.
DDR 333 interface ceiling
The PC 2700 standard caps throughput at the rated 333 MT/s, so bandwidth cannot exceed this limit regardless of system capability. Builders needing higher density or faster transfers must select a different memory generation.

Questions about this item
How much power does the 1GB DDR 333 module draw at its rated 2.50V during all-day use?
The module runs at 2.50V unbuffered without a heat spreader, so power draw stays low for a 1GB stick.
What must my laptop already have to accept this CT12864X335 stick?
A free 200-pin DDR SO-DIMM slot and a motherboard that supports DDR 333 (PC 2700) at CL2.5.
Will this CL2.5 333 MHz module slow down if paired with older CL3 memory?
The system will run all modules at the slowest speed and loosest latency present.
