DDR2 533 upgrade kit for select desktops

This OWC kit supplies 8 GB of DDR2 533 memory as four 2 GB unbuffered non-ECC UDIMMs. The modules run at 1.8 V with CL4 latency and conform to the PC2-4200 JEDEC standard. They are intended for desktop systems that accept 240-pin DDR2 memory.

Suits systems requiring matched 2 GB modules

The four-module pack is built for platforms that populate four slots and benefit from matched capacity and speed. Builds needing a single larger module, ECC support, registered buffers or a different DDR generation should select a different product.

240-pin DDR2 533 PC2-4200 CL4 specification

The decisive specification is the 240-pin DDR2 533 PC2-4200 CL4 interface at 1.8 V. Only motherboards that explicitly support this exact combination will accept the modules.

Questions about this item

What motherboard slot is required for these 240-pin DDR2 modules?

The kit uses standard 240-pin DDR2 UDIMM slots found on compatible desktop motherboards.

Can I mix these CL4 533 MHz sticks with slower DDR2 modules already in my system?

The motherboard will run all installed DDR2 memory at the speed and timings of the slowest module present.

How do I confirm the 8 GB kit is recognised at 533 MHz after installation?

Check the BIOS memory summary or a system-information tool; it should show 8 GB total running at DDR2 533 (PC2-4200) with CL4 timings.
