Quote:Originally Posted byLotta differing user experience that's for sure.UEFI 1501 has been fine for me, where as UEFI 9920 does not hold the same OC, at same settings for me. Again UEFI 9943, 1401, 1403, 1403-SP42M and Elmor's used same setup.Many have sensor issues. I have not, since using board from launch. I have only not used UEFI 0082 and 0003, but all else have been used. My only issue with fans was early March when HWINFO didn't access Super IO chip correctly, after that 0 issues. I have used UEFI to set/control fans from launch.I have also purposefully updated ASUS EC FW from 0310 to 0312. Keybot FW got updated with UEFI 1501. I have not had dead "Aura", so not had to flash that with fix. I set once static red RGB and that's it. Once or twice there has been mention of non RGB RAM SPD corruption, I have not had that either.Yesterday I did reruns of IBT AVX custom 13312MB in W10C, 0 freezes. I also did RealBench v2.54 in W10C, stress mode 16GB, again 0 freezes. This morning I did 10 loops of IBT ABX custom 13312MB with CB15 performance bias enabled, whilst on 3.8/3333 Fast, again 0 issues.For a lengthy while I used Super IO Skew: [Auto], now for few months I have had it as [Disabled]. Not seen any performance loss with this setup, not seen any issues with OC. I just opted to use [Disabled] as the help string said if an OC has an issue with it then disable. So more of preemptive option toggle then needed for my setup.I have also always used ASUS EC enabled in HWINFO.Only case I have sticking window movement is W7 when run HCI Memtest (16x 850MB). This lasts for ~approx few minutes when application is started, after that AOK.As stated before I have used 3x differing RAM sets, with differing RAM IC, 4x differing CPU, I have lost count how many times I have had board out to swap CPUs. Only in the past week or so it has been uninstalled and reinstalled 3 times, today will be it's 4th turn.Yeah, in the beginning BIOS 1501 was working good for me too, only after a while i got these weird sensor readings and the fans had a mind of their own. Just yet i was playing Dirt 4 and the fans start ramping up to 100% while the CPU is only at 40 c.. Went to BIOS but no matter the setting, i couldn't get them to slow down unless i unplug the fans.Sensor readings are also all over the place. After a while monitoring and a few tests the CPU Tctl is normal but CPU and motherboard temp were acting weird and i was getting readings like -79 lol.Vcore is also all over the place, in order to get 1.375 which my CPU needs in order to be stable at 3.875 GHz, i need to set 1.38125 vcore in BIOS and use LLC level 4. Now i set vcore to 1.375 and LLC to level 2 and i get as low as 1.331 in Windows, that's an ridiculous vdroop. I don't know if Pstate overclocking voltages are different but at the previous 1403 BIOS i set 1.350 with LLC to level 2 and i got 1.375 Vcore in Windows. Now i can overclock via normal overclock menu but it needs higher LLC and higher Voltage..Now i am running 9920 BIOS again and fans and sensors are normal again.. So in short, the new 1501 BIOS didn't do anything for me but reading the sensors incorrectly and fan controlling goed out the window.
