@Nitish.s22 thanks, I was able to install the bios, although something horrible has happened. After I installed the bios, my computer's boot time has gone up from 6 seconds to 30 seconds and my graphic card seems to be throttled down by more than 75% of that it use to be (using Warframe as a benchmark: use to average at 120fps now I average between 15-30fps). I also have nvInspector and was able to adjust the memory clock offset but after the unlocked bios I cannot change the offset, it just keeps reverting back to zero. I have reinstalled all the dell bios A08-A13 (A05 and A02 refuse to install) and I have reinstalled the A11 Unlocked bios multiple times but this problem is now in all of them. In the A11 unlocked version I have changed the display from SC to PEG and disabled the integrated graphic card but that caused my screen to go black and my computer started a 8 beep rhythm. I removed the CMOS battery and placed it back in and held the power button for a minute and the bios reset and was surprised to see I was able to edit the memory clock offset but my computer was idling at 68C instead of its normal 57C and after a restart I couldn't edit the offset and I'm back to square one again. Can anyone help? edit: Fixed.
