A320 motherboard review.
The A320 motherboard is a good value entry-level companion to AMD's Riptide, although it's slightly unfortunate that there's a dearth of ITX Mini models, with only two previous offerings from ASRock. The motherboard is a standard Mini-ITX mini-board model with AM4 slots compatible with 1st and 2nd generation RuiLong CPU/APUs, 7th generation APUs, and Sleipnir X4/200 series, up to eight cores, and the only pity is that the A320 has been confirmed by AMD to no longer support 3rd generation RuiLong.
