SKU CH-V58J-KR3TZ

A 4 GB DDR2 desktop memory kit of two 240-pin modules running at 533 MHz with CL4 latency and 1.8 V operation

  • Capacity4GB (2 x 2GB)
  • CAS LatencyCL4
  • Ready for DDR2 upgrades with 533 MHz speed
  • Smooth multitasking from 4 GB dual-channel kit
  • Stable operation at CL 4.0 latency
  • Broad motherboard fit via 240-pin DIMM
  • Reliable modules tested before shipping

Kit capacity and fit

This kit supplies 4GB of DDR2 desktop memory as a matched pair of 2GB modules. It is intended for older systems that accept 240-pin unbuffered DIMMs running at 533MHz with a CAS latency of 4.0. Builders restoring or upgrading legacy workstations will find the specification a direct match.

Sustained-load behaviour

Each module operates at the standard 1.8V and is tested individually before dispatch, reducing the chance of errors that can appear during long sessions. Non-ECC, non-parity chips mean the kit suits typical desktop workloads rather than servers that require error correction. The PC2-4200 and PC2-4300 ratings indicate the same 533MHz data rate under continuous use.

Compatibility checklist

Verify that the motherboard provides 240-pin DDR2 slots and supports unbuffered, non-ECC memory at 533MHz. Confirm the board accepts 1.8V modules and can run at CL4 timings without manual adjustment. Buyers who need ECC, registered DIMMs, higher capacities per slot, or a different voltage should look elsewhere.

Perguntas sobre este artigo

How much heat or power draw should I expect from the 1.8 V DDR2 modules running at 533 MHz all day?

Each module operates at 1.8 V and 533 MHz, so power draw and heat stay low compared with higher-voltage DDR or faster DDR2 speeds; standard desktop airflow is normally sufficient.

What motherboard slot and memory type must I already have for this 240-pin DDR2 kit to work?

You need a desktop motherboard with 240-pin DDR2 DIMM slots that accept non-ECC, unbuffered PC2-4200/PC2-4300 memory running at 1.8 V.

Will these CL4 533 MHz sticks run stably alongside older CL3 or slower DDR2 modules I keep installed?

The motherboard will clock all installed DDR2 to the slowest module's speed and loosest timings, so CL4 533 MHz sticks will down-clock to match older CL3 or lower-frequency DDR2 automatically.
