well i'm not going to lie that crosshair v formula 990 board he uses has a few settings i don't have, and wouldn't mid to
and i wonder why i can't find spread spectrum setting anywhere in my bios... maybe gigabyte decided it's not neccessary? no idea.
BUT - the reality is this board handles itself well if you just leave most things on Auto
here's an example of my 100% stable 4.5ghz OC only using multiplier
now to go further than 4.5ghz or if you want to get the same numbers using fsb overclocking things can get a bit more tricky:
to get 4.7 ghz i went for:
BCLK (fsb) 221mhz
Multiplier 21
Cpu Vcore 1.45625
NB Core 1.25
Dram voltage 1.55 (i have 1.5 voltage ram) in case you have 1.65voltage stock probably just leave it alone at that... atleast don't go over 1.7
reduced system memory multiplier one notch to 8.0 so with this FSB setting ram ends up @ 1792mhz (1866 stock) in your case different since you have 1600mhz - main idea just to keep it running slower rather than faster for more stability/ you might even want to go lower in some cases
Vcore Loadline Calibration - Extreme
all other voltages to Auto again
i tried following these guides amd play with other voltage settings and not once i seemed to get a better result than just leaving them on auto...
but manual still offers you better finetuning and possibility to reduce temperatures a bit by only using as much voltage as necessary
but again... if you push for such high oc it's a territory where you'll have to experiment cuz every cpu acts a lil' different,
and there's a chance that some more experienced overclocker could get something more out of my cpu/board since i don't fully understand all the settings either
about APM and HPC:
http://www.ronwoods.us/2014/02/what-does-amd-application-power.html
this link seems to have the best info... i'm not sure jayztwocents did the right thing in his video
atleast on benchmarks i seem to get slightly better score with HPC enabled
you might want to disable APM but in reality i didn't notice any diffrence wether it was on or off...
i went with power saving features like the core c6 states etc. disabled since the general idea is they can cause instability when oc' ing
but in reality i tested it with them on and seemed to work fine -
they reduce your cpu heat and power consumption and possibly extend lifetime while idling or just web browsing etc by downclocking it and reducing voltage to 0.9-1.0 volts
you can also pay with the offset voltages to get a similar scenario with your overclock... i haven't tried those yet
you see i'm also just learning and it's been some 8 months since i got this pc... just haven't put too much time in it since i'm happy with my settings
why i gave up on some of the voltage settings and just left them on auto?
well the 4.9ghz i posted earlier has all of them on auto... just cpu vcore set to 1.5
without auto i actually seemed to hit a wall and couldn't get it to run higher than 4.8..
also consider the Asus M5A97 EVO R2.0 as a alternative for this gigabyte board...
should be good too - maybe even better,
the 8+2 power phase design sounds tasty because you know "more is better"
but that is not always the case with electronics and that board should be very good too
[update2] - fsb overclocking vs multiplier makes very little real world difference overall, maybe 1-2% or something like that,
i guess depends on scenario
