Hello, with the X370 / X470 board, a fixed Vcore can be set easily. The new BIOS is P1.10

Yes, but when i fix the VCORE at 1.20V (for exemple) in bios settings, this paraemter is no effect. I see the new 1.1 bios, but he is BETA.... |

Probably that is because VRM based on ugly ISL95712. X370 K4 have IR35201, and Killer SLI first revisions (up to 1.05). Asrock have IR35201 only on top motherboards now. They remove even voltage offset control from cheap mobos, like AB350M Pro4, but stay in middle mobos like Fatal1ty X370 Gaming X. Mobos based on ISL95712 from asrock on latest 4.6 / 4.7 BIOSes unusable, because they not have any voltage control. All that you have - offset on mobos in middle segment. Voltage control over freq control - does nothink!!!!!!!!! I set even 1V, but bios hw mon page show 1,26V. Looks like asrosk keep in bios some table: freq-voltage, and ignore voltage control that user set in bios over freq control. Only offset controls work, if you have it. With new agesa 3b (AB350M Pro4 bios ver 4.73B) asrock switch voltage control to auto (it is internal setting, probably compile time), now hw mon show 0,976V and probably on CPU full load voltage will grow up to value set near freq control. It is terrable situation with mobos that VRM based on ISL95712. Im not overclocker, I prefer a little downclock, downvolt but I cant do that, espessialy with AB350M Pro4 because it does not have any controls that work. |
