For CMFD miners: FreeForGem 1.7.6 is out —
release (miner thread:
5596770), 1% dev fee, NVIDIA RTX 20+ and AMD Radeon (Windows), about 7 GB of free VRAM.
What changed for CMFD: the automatic undervolt (--auto-uv) now climbs in 30 MHz steps and refines with 15 MHz inside the first failed interval, no longer stops early on a power-limited card, and re-validates the offset while mining. The HiveOS profile's memory lock (e.g. 810 MHz set for Pearl) is no longer applied to CMFD — on one rig it had made CMFD about 6x slower (3.7 instead of ~21 FW/s). Windows idle mode works for CMFD too (the engine pauses while the PC is in use).
Measured on 4x RTX 3070 at a 220 W limit: GPU0 21.29 -> 23.16 FW/s (+8.6 % FW/kWh), GPU2 21.12 -> 23.27 FW/s (+10.3 % FW/kWh) at the same power.
