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

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.
