Kingston ValueRAM DDR3 1GB Module

This 1GB DDR3 DIMM is built for desktop systems that require industry-standard memory with error-correcting code support. It suits white-box or generic computers where stability matters more than peak speed. The unbuffered design keeps the module simple and reliable for everyday workloads.

240-Pin ECC Unbuffered Build

The module uses a 240-pin gold-edge connector and operates at the standard 1.5 V DDR3 voltage. ECC circuitry detects and corrects single-bit errors without registered buffering, so it fits directly into consumer desktop sockets that accept ECC unbuffered DIMMs. CL7 latency at 1066 MHz delivers consistent timing for basic productivity tasks.

Check Motherboard ECC Support Before Ordering

Verify that your motherboard chipset and BIOS enable ECC on unbuffered DDR3 slots; many consumer boards ignore the extra parity bits. Confirm the board accepts 1GB density modules and runs memory at 1.5 V without requiring lower-voltage parts. Systems limited to non-ECC memory or higher-density-only slots cannot use this stick.
