MX150 Only!
According to AptioFixPkg's README, "[c]ertain firmwares fail to properly initialize 0xE2 MSR register (MSR_BROADWELL_PKG_CST_CONFIG_CONTROL) across all the cores....
CFG Lock option is available on most APTIO V firmwares, although it may be hidden from the GUI. If VerifyMsrE2 reports that your 0xE2 register is consistently locked, you may try to unlock this option directly."
Cyb and FallenChromium created script to unlock. Please download DVMT_and_0xE2_fix and read README to unlock.
After that, you should delete Clover MSR 0xE2 patch.
