512 MB PC133 Registered ECC DIMM

This Kingston module provides 512 MB of SDRAM on a 168-pin DIMM running at 133 MHz with CL3 latency and 3.3 V operation. It is a registered ECC stick designed for desktop systems that require error-correcting code memory with a register buffer. The PC133 specification suits legacy platforms built around this memory standard.

Suits owners of legacy desktops needing registered

This module fits systems that specifically accept registered ECC SDRAM DIMMs at 133 MHz. It is not suitable for motherboards that only support unbuffered non-ECC memory or those requiring different pin counts, voltages, or memory technologies. Builders working on modern platforms should look elsewhere.

Highlights

Questions about this item

Does this 512 MB registered ECC module require a motherboard with 168-pin DIMM slots and 3.3 V SDRAM support?

Yes, the module uses a 168-pin DIMM form factor and operates at 3.3 V, so the motherboard must provide matching slots and voltage for SDRAM memory.

Can I mix this PC133 CL3 registered ECC stick with unbuffered non-ECC SDRAM already in my system?

No, registered ECC modules cannot be combined with unbuffered non-ECC memory; the motherboard chipset and BIOS must support registered ECC operation for all installed sticks.
