512 MB DDR 333 module

This Kingston ValueRAM stick supplies 512 MB of DDR 333 memory rated at PC 2700 with a CAS latency of 2.5. It is built for older desktop systems that require 2.5 V unbuffered DIMMs without a heat spreader.

Capacity and headroom

The single 512 MB module handles lightweight office applications and legacy operating systems comfortably. Memory-intensive tasks or modern multitasking will exhaust the available capacity quickly.

Upgrade context

It replaces a failed or smaller DDR 333 stick in boards that accept PC 2700 speeds at CL2.5 timing. The upgrade is worthwhile only when the platform cannot use larger densities or faster DDR standards.

Questions about this item

Will this 512 MB DDR 333 module run with my existing PC 2700 sticks?

Yes, it matches the DDR 333 (PC 2700) speed and 2.50 V voltage so it will operate alongside identical modules.

How can I confirm the CL2.5 timing is active after installation?

Check the memory tab in CPU-Z or the BIOS SPD readout; both should report CAS latency 2.5 at 333 MHz.

Does the KVR333X64C25/512 come with a heat spreader or any extra accessories?

The module has no heat spreader and ships as a single DIMM only; no cables, brackets or adapters are included.
