256 MB PC133 Unbuffered SODIMM
This AddOn module delivers 256 MB of PC133 SDRAM with a CAS latency of 3 and a 3.30 V operating voltage. It is an unbuffered, non-ECC stick built to JEDEC standards for desktop upgrades. The part number is AO16C3264-PC133.
Suits legacy desktops requiring PC133 SDRAM
Builders restoring or expanding systems that accept PC133 unbuffered memory at CL3 can use this module. It is not suitable for machines that need registered or ECC memory, nor for platforms that require DDR or later memory technologies.
PC133 speed rating determines fit
The single specification that decides compatibility is the PC133 speed rating combined with the unbuffered, non-ECC, CL3 profile at 3.30 V. Only boards designed for this exact SDRAM generation will recognise and run the module correctly.

Vragen over dit artikel
What motherboard slot and voltage must my desktop already provide for this 3.30V PC133 module?
The module fits a standard 168-pin SDRAM DIMM socket and requires a 3.30V supply from the motherboard.
Will this unbuffered CL3 stick run reliably in a system that currently uses registered or ECC memory?
No, mixing unbuffered non-ECC memory with registered or ECC modules prevents the system from booting.
How can I confirm the stick is detected at PC133 CL3 after installation?
Enter the BIOS or run a memory-identification utility; it should report 256MB at 133MHz with CAS latency 3.
