Industrial Socket 478 Motherboard

The Roby Technology 845GV board targets industrial PC builders who need a new ATX motherboard with native ISA slots for legacy expansion cards. It fits Socket 478 Celeron and Pentium 4 processors and supports up to 2 GB of DDR memory.

Sustained-load behaviour

The Intel 845GV plus ICH4 chipset delivers stable throughput for long-running industrial workloads rather than short benchmark bursts. Onboard Realtek RTL8100C LAN and ALC655 audio remain active without additional cards, keeping the PCI and ISA slots free for specialised I/O.

Decisive specification

Three full-size ISA slots and two PCI slots coexist on a single ATX board, a combination that determines whether your legacy data-acquisition or control cards can be installed. If the application requires more than three ISA devices, this board cannot meet that need.

Questions about this item

How much heat and noise should I expect from the 845GV motherboard when it runs continuously in an industrial PC?

The board itself has no active cooling; thermal output and fan noise depend entirely on the Socket 478 Celeron or Pentium 4 processor and the case fans you install.

Which components must I already have to make this 845GV ISA motherboard operational?

You need a Socket 478 Celeron 4 or Pentium 4 CPU, up to 2 GB of 184-pin DDR 266/333 DIMM memory, an ATX power supply, and a standard ATX chassis measuring at least 255 x 180 mm.

Will my legacy ISA expansion cards work alongside the newer PCI devices on this 845GV board?

Yes, the board provides three ISA slots and two PCI slots simultaneously, so legacy ISA cards and PCI peripherals can be installed and used together.
