DDR2 533 dual-channel kit

This OWC kit provides 2GB of desktop memory as two matched 1GB modules. They run at DDR2 533 speed with a CL4 latency and 1.8V operation. The unbuffered, non-ECC DIMMs use the standard 240-pin form factor. A black PCB completes the specification.

Suits older desktops needing a matched pair

The dual-channel configuration benefits systems with two available slots that support PC2-4200 modules. Builders repairing legacy workstations or upgrading basic office machines will find the JEDEC-standard parts straightforward to install. Systems requiring ECC, registered DIMMs, higher speeds or larger single modules should select a different product.

240-pin DDR2 533 UDIMM decides fit

The 240-pin unbuffered DDR2 533 interface is the single specification that determines whether this kit fits a motherboard. Only boards designed for PC2-4200 non-ECC memory at 1.8V will accept these modules. Verify the manual before purchase.

Questions about this item

Will these modules work in a motherboard that only has PC2-4200 slots?

Yes, the kit is rated at PC2-4200 and runs at 533 MHz, so it matches that slot specification exactly.

Do I need to install both sticks together for the system to boot?

The kit is sold as a matched pair for dual-channel operation, but each 1 GB module can be used individually if your board only has one free slot.

Is any special voltage setting required in the BIOS?

The modules operate at the standard 1.8 V for DDR2, so most desktop BIOSes will configure them automatically without manual adjustment.
