update到新的bios (6/30/2014,V4.3)后,超频确实稳定了不少。我用简单模式, 只改倍频,以前改到4300就不稳定了,update到最新的bios后,4600不大稳定,4500 很稳定。估计是系统自动增加电压改善了。:P cpu-z显示在4500满载(Intel burn test) 运行时,电压为 1.34V. http://us.msi.com/product/mb/Z97_PC_Mate.html#download Note from the txt file inside 601-7850-100 = BIOS 4xx = Z97 PC Mate 601-7850-110 = BIOS 5xx = H97 PC Mate ------------------------------------------------- Z97 PC Mate (MS-7850) V4.3 BIOS Release ------------------------------------------------- 1.
