From aa2b8652959498fb94e4c5803d1fa6cd6f621605 Mon Sep 17 00:00:00 2001 From: igneum-labs <337424239+igneum-labs@users.noreply.github.com> Date: Thu, 8 Oct 2026 11:23:54 +0000 Subject: [PATCH] 0.3.25 AMD knob: the RX 9070 XT's measured efficient point, 149 W, in the tuner's ceiling table (the first grid on the knob, PC 1, 8 October 2026, 12:10 BST, run-ca3-pc1-amd-grid-9070-20261008-b, 24 of 24 rows ok, the app's own hash_now, the card reset at the end). The rate is flat at 18.93 to 18.98 MH/s over the whole ladder: the knob moves watts only, so the knee never comes and the stop rule reaches the floor; the efficient point is both floors (clock offset -500, about 2,920 MHz where ADLX clamps; power limit -30): 149.3 W at 18.96 MH/s, 0.127 MH/W, 24 percent under stock's 195.8 W at the same rate. The clock offset alone takes 196 to 159 W; the power limit alone does nothing until -30 (184 W).
