A-Tech 8GB DDR2 533MHz 4x2GB Desktop RAM

SKU CH-TA5H-59G7H

Adds 8 GB of DDR2 533 MHz memory across four unbuffered 240-pin DIMMs running at 1.8 V with CL4 timing

  • Capacity8GB (4 x 2GB)
  • Type240-Pin PC RAM
  • SpeedDDR2 533 (PC2 4200)
  • Tested Frequency533

Capacity 8GB (4 x 2GB)

Speed DDR2 533 (PC2 4200)

  • Boosts multitasking with 8GB total capacity across four modules
  • Runs at DDR2 533MHz speed for responsive desktop performance
  • Operates at standard 1.8V DDR2 voltage for broad compatibility
  • Uses unbuffered non-ECC DIMMs for straightforward installation
  • Tested to CL4 timing for reliable operation

8GB Quad-Channel DDR2 Kit

This kit contains four unbuffered DIMMs totalling 8 GB of DDR2 memory. It is intended for desktop systems that accept 240-pin modules running at the PC2-4200 standard. Each module operates at 1.8 V with a tested CAS latency of 4. The package targets owners of older AMD or Intel platforms needing a straightforward capacity increase.

Steady-State Operation at 533 MHz

All four sticks are validated to run continuously at 533 MHz without requiring voltage increases beyond the 1.80 V DDR2 norm. The Major Brand Chipset and factory screening aim to keep error rates low during extended multitasking sessions. Unbuffered topology means the memory controller drives each module directly, so signal integrity depends on motherboard trace quality at this frequency.

Pre-Installation Checks

Verify that the motherboard supports DDR2 DIMMs at the PC2-4200 speed grade and can populate four slots in a quad-channel arrangement. Confirm the BIOS recognises 2 GB density per slot and that no registered or ECC-only restriction applies. Ensure the board’s voltage regulator can supply 1.8 V to all populated sockets simultaneously.

أسئلة حول هذا المنتج

How much power and heat do four DDR2 533 modules at 1.8 V produce when the system runs all day?

Each module operates at the standard DDR2 voltage of 1.8 V. With no heat spreaders fitted, the DIMMs rely on case airflow to stay cool during continuous use.

What must my motherboard provide to run this 4 x 2 GB kit?

The board needs four 240-pin DDR2 slots that support PC2-4200 unbuffered non-ECC memory at 1.8 V and must accept a total of 8 GB.

Can I mix these PC2-4200 CL4 sticks with slower DDR2 modules already installed?

The kit is tested at 533 MHz with CL4 timing. If slower DDR2 DIMMs are present, the memory controller will run all modules at the lowest common speed and latency.
