In a forum post Pepinorang from MSI informed us that he updated the MSI Z170A XPOWER GAMING Titanium Edition overclocking thread with the latest BIOSes, an updated version of the LN2 OC Guide, a new version of the MSI GAMING CPU-Z skin and a version of the Command Center Lite software which works with all BIOS versions.
The LN2 OC Guide update includes a revision of the BIOS and software utilities, revision of the LN2 overclocking tips and voltage table, revision of the CPU ST/ST V6 and PLL OC Voltages, an updated guide on how to max out the CPU frequency, and more details on how to improve the CPU coldbug and coldbootbug. Also included is the hardmod for CPU ST which helped Vivi a lot in his recent testing.
