Product Description
iBASE IB935RF PICMG 1.3 Full-Size CPU Card – LGA775 for Intel Core 2 Duo/Quad, Q35 Chipset, Dual Gigabit LAN, SATA RAID
This used iBASE IB935RF is a high-performance PICMG 1.3 (SHB Express) full-size single-board computer designed for industrial and embedded applications requiring robust expansion capabilities . It is a full-size CPU card (338mm x 126mm) that plugs into a PICMG 1.3 backplane, providing access to PCI Express and PCI expansion slots.
Powered by the Intel Q35 Express Chipset with the ICH9R I/O Controller Hub, this board supports a wide range of LGA775 processors, including Intel Core 2 Quad, Core 2 Duo, Pentium Dual-Core, and Celeron 400 Sequence CPUs on an 800/1066/1333 MHz front-side bus.
This card is the “RF” variant of the IB935 series, which distinguished itself from the standard IB935 (ICH9) by utilizing the advanced ICH9R south bridge. This upgrade provides support for RAID 0, 1, 0+1, and 5 across its four SATA II ports, as well as an additional second Intel Gigabit Ethernet controller . This makes the IB935RF a superior choice for applications requiring high data availability or dual network redundancy.
Condition Note: This unit is untested and sold as-is. It is a legacy component for industrial system repair or vintage computing projects. No CPU, RAM, I/O shield, cables, or backplane are included unless specified.
