Capacity and use

This 512 MB DDR400 module is built for older desktop systems that require PC 3200 memory. It suits owners restoring or maintaining a legacy platform where higher-capacity sticks are not supported.

Speed and latency

The stick runs at DDR 400 (PC 3200) with a CAS latency of CL3 and a rated voltage of 2.60 V. These specifications determine whether the module will post and run stably on a given motherboard.

Build integration

No heat spreader is fitted, so the module fits in tight slots and works with standard CPU coolers. It occupies a single DIMM socket and leaves remaining banks free for additional PC 3200 memory.

商品問答

Will this 512MB DDR400 module fit my desktop motherboard?

The module uses the standard 184-pin DIMM form factor for DDR400 desktop memory. Check your motherboard manual to confirm it accepts DDR400 (PC3200) DIMMs and has a free slot.

What do the CL3 and 2.60V ratings mean for stability?

CL3 indicates the CAS latency timing at DDR400 speed, and 2.60V is the required operating voltage. Your motherboard must support this voltage and be able to run at CL3 timings for the module to work correctly.

Can I add this stick alongside my existing DDR memory?

Mixing modules works best when speed, voltage and timings match. This stick runs at DDR400, 2.60V and CL3; your existing memory should share those specifications to avoid instability.
