The newest community items on cmp.wiki, from November 3 to 5, 2026: ECC on the CMP 170HX without a patched driver, P2P behind PCIe switches, two hardware warnings and prices that have not come down. Each item gives its wiki status: Reported means one person's result, and Warning marks something that damaged hardware.
Unlocks and drivers
- gpu-unlock 3.0 and ECC (Reported): @zagitta showed nvidia-smi reporting ECC enabled on an 8 GB card "without any patching of nvidia stuff" (November 4, 2026), and on November 5 said HBM ECC fault injection now works for checking it before release. Nothing is released yet; see ECC.
- Proxmox and Gen2 (Reported): running the unlock on the host and a clean, unmodified driver in the VM keeps Gen2, per @._.patrik, with @prometasfw describing the same split (November 3, 2026); see Proxmox Gen2 passthrough.
P2P and hardware
- P2P behind a PEX88096 board (Reported): @replacedriver47 got P2P working after changing an ACS setting on the switch ports, apparently without a large BAR1 (November 4, 2026). No numbers or content check yet; see P2P.
- Eight cards on two PEX9797 switches (Reported): @markshowa runs eight CMPs in a single-root server with P2P and GPUDirect Storage working (November 3, 2026); see Supermicro SYS-4028GR-TRT2.
- NVLink on the 10 GB card (Reported): @ghostinthedatacenter_87281 found a resistor blown off one card, which took a long time to trace, and ordered 3.3 V load switch parts (November 4 and 5, 2026). No link has trained yet; see NVLink.
Warnings
- Check HBMVDD on a card with memory errors (Warning): a failed R815 strap resistor set 1.4 to 1.52 V on the memory rail, per @dalzyyy (November 3, 2026); do not keep running a card that reads above 1.35 V. See Memory errors and ECC.
- A dual 24-pin ATX splitter joining two 1600 W PSUs melted once, per @darkmaniac7 (lab notes, November 4, 2026); see Power and cabling warnings.
Prices
- Still no drop (Reported): @c133 put unlocked 8 GB cards at 3,000 to 3,500 USD (November 3, 2026); two 8 GB cards listed in Europe at 2,500 EUR each were gone the same day, per @bvls7857 and @markshowa (November 4). See Price history and market and the Price log.
