matstatman runs four cards on a used ASUS X99-E WS (PCIe Gen3) with an E5-2695 v4 and DDR4 UDIMM. {{Source|handle=matstatman|date=2026-10-07|link=https://discord.com/channels/1518634379604136178/1518692084729511967/1557532188772405271}}<br />{{Source|handle=matstatman|date=2026-10-07|link=https://discord.com/channels/1518634379604136178/1518692084729511967/1557532980673642557}}<br />{{Source|handle=matstatman|date=2026-10-15|link=https://discord.com/channels/1518634379604136178/1528826330454429706/1560411782588137553}} The board has a PLX switch (Miséricorde). {{Source|handle=wakeupmbrc1|date=2026-10-18|link=https://discord.com/channels/1518634379604136178/1518692084729511967/1561405667368108093}}<br />

== Known issues ==<br />
* PCIe slot 5 never accepted x16. {{Source|handle=matstatman|date=2026-10-07|link=https://discord.com/channels/1518634379604136178/1518692084729511967/1557532188772405271}}<br />
* The board was bought used from China for about 200 USD and was bad on arrival; later another slot lost x16 and runs x8. {{Source|handle=matstatman|date=2026-10-16|link=https://discord.com/channels/1518634379604136178/1528826330454429706/1560618524995489825}}<br />{{Source|handle=matstatman|date=2026-10-16|link=https://discord.com/channels/1518634379604136178/1528826330454429706/1560647340392718397}} Waka324 saw the same x8 symptom on his early cards from a bad capacitor mod, so check the card too; endsjeremy advises against used boards unless you can repair them. {{Source|handle=cmdrwaka324|date=2026-10-16|link=https://discord.com/channels/1518634379604136178/1528826330454429706/1560640558685233254}}<br />{{Source|handle=endsjeremy|date=2026-10-16|link=https://discord.com/channels/1518634379604136178/1528826330454429706/1560647417022648421}}<br />
* Memory is capped at 128 GB (non-ECC unbuffered). {{Source|handle=matstatman|date=2026-10-07|link=https://discord.com/channels/1518634379604136178/1518692084729511967/1557532392271384597}}<br />

matstatman's wish list for his next board: ATX, IPMI or vPro, four x16 slots. Miséricorde's answer was an EPYC board (MZ32-AR0, EATX). {{Source|handle=matstatman|date=2026-10-16|link=https://discord.com/channels/1518634379604136178/1528826330454429706/1560648097212801025}} See [[Gigabyte MZ32-AR0]].<br />
