SKU CH-257J-HSDX4

ATX server motherboard with Socket 370 supporting 133 MHz SDRAM up to 4 GB

Socket 370 server board for legacy maintenance

This Supermicro ATX motherboard fits Socket 370 processors and runs SDRAM at 133 MHz. It supports up to 4 GB of memory across its DIMM slots. The board measures 12 in by 9.6 in and suits technicians who maintain or repair older server platforms. It is not for builders who need modern memory types or contemporary CPU sockets.

Passive cooling suited to vintage chassis

The board draws modest power typical of Socket 370 systems and relies on case airflow rather than active onboard cooling. No fan headers or thermal sensors are listed, so noise depends entirely on the enclosure fans installed. It is not for deployments that require monitored thermal management or high-wattage processors.

Questions about this item

How do I install this Socket 370 motherboard into an ATX case, and which step is often missed?

Mount the board using the standard ATX standoff pattern, then attach the 12 in by 9.6 in I/O shield before securing screws; the shield is frequently forgotten until the board is already fixed down.

What maintenance will the SDRAM memory slots need over time?

Reseat the SDRAM modules if the system fails to post, and replace any stick that shows corroded contacts; the board supports up to 4 GB across its slots.
