I just built my new pc and I am having alot of frustration with the G3258 anniversary edition cpu. Not sure why but I can't even get a stable 4.0 overclock without raising the voltage much higher then I'd like. Currently I've got my cpu running at 4.0ghz at 1.325 volts with 1.9 on the input voltage(it sets automatically). Not sure what I'm doing wrong. Everything is being done on the latest asrock bios version 2.30. None of asrocks overclock presets worked and failed as soon as I restarted. Not sure if I just drew the worst chip possible or if there's something I'm not seeing. I'll be reading the replies later as I am extremely tired but I will be eager to read the responses when I wake up. Thanks to those who can help ahead of time.
Even if it were a bad chip I'd say you can do better than 4GHz on 1.325V, my first thought is that ur settings arent optimal, you only upped the multiplier right? For stability you should also up the ring ratio & voltage. I've got a G3258 in one of my systems too and it's running at 4.2Ghz on 1.25? volts, with a very questionable legacy PSU.
Core Voltage - Override - 1.3v Cache Voltage - Override - 1.15v CPU Load-Line Calibration - Level 3 Power Saving Mode - Disabled
And see if that will remain stable at 4.0GHz. If it does, push the multi another step and retest. If it doesn't, then you may be looking at a dud chip because 1.3v at those speeds is already pretty substantial.
So I tried your settings and for the first 30-40 minutes it was fine running prime95, but croaked around the 45min mark. I may just honestly chock this one up to the silicon lottery and take what I can get.
