Miséricorde runs two cards on a Huananzhi X99-F8 (DDR4) and calls the Huanan boards the best base for two 8 GB cards: cheap, PCIe 3.0, NVMe, working sleep, fast boot, and better behaved than typical AM5 boards. Source: @wakeupmbrc1, 2026-10-07

Variants
- X99-T8 (DDR3): his cheap recommendation is an X99-T8 with an E5-2696 v3 and 256 GB DDR3. Source: @wakeupmbrc1, 2026-10-07
Source: @wakeupmbrc1, 2026-10-07 Buy the v2 revision of the T8: the first one lacks Xeon v4 support (endsjeremy). Source: @endsjeremy, 2026-10-07 - TD8 (C612): the first and last PCIe slots and 4 lanes for the M.2 come off the first CPU, so it runs on one CPU (endsjeremy). Source: @endsjeremy, 2026-10-07
- Two Xeon v4 SKUs also take DDR3, including the E5-2686 v4 (about 25 USD); none of the DDR3-capable v3/v4 Xeons are on Intel's pages, but the AliExpress listing for the X99-T8 has the CPU list (Petri Krohn). Source: @petrikrohn_26497, 2026-10-07
- The F8 has 8 RDIMM slots and proper VRM cooling but a weak BIOS (meatsus). Source: @meatsus, 2026-10-19
Limits
- Two cards. The F8/T8 slot spacing seats two cards, not three. Source: @endsjeremy, 2026-10-07 LGA2011-3 CPUs have 40 lanes; four cards need a PLX board or card. Source: @wakeupmbrc1, 2026-10-16
Source: @wakeupmbrc1, 2026-10-18 - Memory. One CPU on DDR3 tops out at 128 GB; DDR4 RDIMM at 256 GB per CPU (endsjeremy). Source: @endsjeremy, 2026-10-07
Source: @endsjeremy, 2026-10-07 These boards are fussy about memory: the BIOS lacks a full timing table, so use exactly the right memory (same revision), at most 256 GB and 32 GB per stick, never 512 GB, and buy the common 12-layer boards with at least 6 VRM phases (endsjeremy).
