G3258 Fails to Power On When EIST Is Turned Off
I've been developing my third g3258 build. This version proved to be a solid chip, achieving an overclock of 4.6 GHz at 1.27 volts. After completing two 12-hour shifts with prime95 blend and a small fft (no crashes) and an overnight memtest, I felt confident about its stability. I performed a clean installation of Windows 7, updated the chipset and Realtek audio drivers (due to accidental installation of motherboard fan control software). Upon rebooting, I observed the clocks returning to their original state. I verified the BIOS and confirmed that the overclock had reset itself. This was the first time I had done this after three days of normal benchmarking and rebooting.
I think the issue might have come from loading an Asus overclocking profile. If I adjust the clocks manually back to 46 and disable EIST, then set the cache ratio to stock without loading the profile, it still stays at 4600mhz. But if I load the overclock in profile, reset the cache ratio to stock, then the system won’t boot and it loads stock CPU clocks while keeping the overclocked cache settings. It could also be related to the cache ratio itself. Just in case, it might be a mix of unstable cache voltages and a tricky BIOS. It seems to work now.
