Every slot comes from the CPU, which is what P2P wants. Some notes call it a Supermicro board; it is Huananzhi&#039;s.<br /> <br /> == What people report ==<br /> * Miséricorde: P2P works on it; it suits 4 cards, or 4 PLX host cards for 8 or more; it comes with or without an ASPEED BMC; it has become more expensive because it is a good GPU board. He suggests splitting every x16 slot to two cards rather than mixing direct slots and one PLX board. {{Source|handle=wakeupmbrc1|date=2026-10-16|link=https://discord.com/channels/1518634379604136178/1528826330454429706/1560651333504082002}}&lt;br /&gt;{{Source|handle=wakeupmbrc1|date=2026-10-16|link=https://discord.com/channels/1518634379604136178/1528826330454429706/1560651754536968212}}&lt;br /&gt;{{Source|handle=wakeupmbrc1|date=2026-10-16|link=https://discord.com/channels/1518634379604136178/1528826330454429706/1560652393497235579}}<br /> * PJ owns one (unopened at the time) and planned 3 cards in slots plus a PLX board with 5 more. {{Source|handle=zingy90210|date=2026-10-16|link=https://discord.com/channels/1518634379604136178/1528826330454429706/1560649338563334226}}&lt;br /&gt;{{Source|handle=zingy90210|date=2026-10-16|link=https://discord.com/channels/1518634379604136178/1528826330454429706/1560651140754972734}}<br /> * OB88594 runs one: the affordable DDR4 + PCIe 4.0 EPYC option with reachable after-sales and occasional BIOS updates, but he has filed many support requests, mostly for immature BMC faults. {{Source|handle=ob88594|date=2026-10-08|link=https://discord.com/channels/1518634379604136178/1518692084729511967/1557567303753662526}}<br /> <br /> == Memory ==<br /> fafinet gets about 120 corrected ECC errors per minute with 8x DDR4-2133 4DRx4 32 GB LRDIMMs on his H12D-8D even though the sticks pass memtest, and runs with &lt;code&gt;&lt;nowiki&gt;mce=off&lt;/nowiki&gt;&lt;/code&gt; (which also hides uncorrectable errors); 8x DDR4-3200 2Rx4 64 GB RDIMMs (512 GB) work fine on the same board.
