# Resizable BAR for Intel GPUs on Old Motherboards

Rod Burlamaqui's arc-rebar project enables Intel GPUs to use resizable BAR on unsupported motherboards. It requires Debian or Ubuntu and a supported Intel GPU. Performance jumps from 15 GB/s to 392 GB/s on an Intel Arc B580 with a 2015 Xeon board.
