Nobody has reported a CMP 170HX in an R720 yet. mlx4 used 32 GB LRDIMMs in one and wondered whether a 170HX would fit. Source: @mlx4, 2026-10-09

Why it comes up
- Real LGA2011 server boards can train 64 GB DDR3 LRDIMMs that X99 boards cannot, which makes old DDR3 servers cheap RAM-heavy hosts (endsjeremy). Source: @endsjeremy, 2026-10-09
Source: @endsjeremy, 2026-10-09 See Consumer motherboards#X99 and X79 (including Huananzhi). - endsjeremy weighs a used dual E5 v3 Supermicro or R720-class board with 512 GB as a rental host: 3 GPUs natively, 6 at x8 with passive risers, under 1600 W. Theory Source: @endsjeremy, 2026-10-21

Before you try
- Check physical fit, GPU power cabling and the 64-bit MMIO options in this generation's BIOS. Server BIOS setup has the checklist.
- Check how you will power the card from the server's GPU power outputs before buying cables; see Cooling and power.
