Okay. Does it matter which one? I guess one would ensure your system ran at whatever clock you set it at base, and the other would boost to the higher clock. In theory you could overclock the base to whatever you want, find the stable point, then lower it to some, and have a boost clock of the stable overclock you found. You could overclock the base to a lower setting like say 4GHz idle, and 4.6GHz if you could get that stable turbo speed. My Gigabyte board seems to need a update. I have the latest bios but Windows and CPUID are both not showing correct values. Windows my base clock with all the Power Saving features turned off at 3.49GHz, with EIST and C6/7 enabled I see the base clock of 3.50GHz under windows task manager, and boost to 3.88GHz. With all that turned off I never seen anything higher at least when I look at it then 3.88GHz it seems to stay at a constant turbo boost according to Windows, but CPUID will show it going from 3890MHz to 1001 every so often.
I was going to leave the power savings features on but an avid gamer that plays Day Z Stand Alone is going to notice some performance issues as I did. The game some how jumps in spikes and I guess the throttling effects it because I lost FPS dramatically in it. It is very unoptimized but I did not care to save power anyway. BF4 I can confirm suffered no performance hit. I am not dissing no on here just was hoping to find someone with some insight on what maybe I don't have set correctly in my bios. I haven't even begin to overclock because at the moment I cannot even understand how to get my CPU to function correctly in WIndows as it seems. I mean it does work great, plays games fine but it bothers me that it is showing different readings? Any help regarding this topic would be great. I suppose my next stop will be to register at the gigabyte forums and ask over there.
