3570K Overclock

The computer is used for university and a bit of gaming so don't want to overclock it incase the computer starts crashing while doing assignments but 3.8GHz will probably do me just fine.

However, what's the best option? Setting CPU Clock Ratio to 34 and enable Turbo Boost or set CPU Clock Ratio to 38 and disable Turbo Boost?

That's the standard turbo boost for the 4 cores.

Set the turbo boost on each core. That way you be sure the CPU will clock down at idle. If you want an easy OC then just the set the cores to 42,42,41,40. That will hardly tax the CPU assuming you have a half decent cooler.

Mine is set to 45,45,45,45 and CPU core is set to a fixed 1.18v no other changes necessary. I do have a Noctua cooler though so it doesn't get above 50 DegC.
 
its not going to crash writing up some notes for uni if it stable in games and stress tests. you should overclock it to a sensible speed above turbo like 4.2 or 4.4 so you get a decent performance boost and then set the voltage correctly so that its stable.
 
I've tried 4GHz by setting the CPU Clock Ratio to 40, disabled Intel Turbo Boost Technology, CPU VCore at 1.2V with VCore Loadline Calibration at Turbo,

However when the core speed clocks down when the computer is not in use, the core voltage always stay at 1.2V?

It won't on a fixed CPU voltage

Try setting CPU v to normal in the voltage list,then try low load line calibration and 40x CPU clock,if stable try going to 42x

Just do 5 runs of ibt

I've set CPU VCore to Normal and LLC to Low with CPU Clock Ratio 42 but the core voltage in CPU-Z is showing 1.272 and sometimes 1.284 when stress testing, seems a bit high?
 
Look for dvid now and try -0.030v

That will reduce your load CPU voltage,if still too high use more negative dvid so maybe -0.040v and so on

Also test for stability with games as it will pass stress tests yet crash quickly in games if CPU v is too low

Does it down clock at idlenow? It should do

-0.105 DVID seems to be stable in IBT/Prime95 tests with core voltage from 1.164, 1.176 and 1.188 in CPU-Z and temps below 60°C

I haven't got any games at the moment but will have soon, if it crashes, I just increase the DVID number until it's stable?

Yes, the core voltage clocks down to 0.960V at 1.6GHz

no -0.110 is too much

always keep the first two numbers 0 so -0.0

did you try -0.030v to begin with?

I tried -0.030 but the core voltage in CPU-Z was 1.236V - 1.248V

EDIT: ok try with -0.065v that should give you around 1.2v at load

if -0.085 is stable the stick with that

remember to play some games later to further test stability,if they crash to desktop you need more cpu voltage

Should I try -0.090-95 to see if it's stable as well?

Just wondering is there a reason to this? Because using -0.105 is stable for 4.2GHz in IBT/Prime95 tests with core voltage from 1.164, 1.176 and 1.888V in CPU-Z
 
if you need -0.105v then yeah use that aslong as it remains stable,you said it crashed with -0.110v though

you'll find if you play some games you'll have to reduce the - dvid a fair bit,maybe to around -0.085v or so to be stable in gaming even if it passes ibt

-0.110V crashed while stress testing but I'm using -0.100 at the moment which gives me 1.176V -1.200V in CPU-Z.

Other settings in the BIOS such as PWM Phase Control, VCore Voltage Response etc are default/auto settings.
 
can set pwm phase control to extreme performance and vcore voltage response to fast

if temps are ok you could up the oc to 4.5ghz? and try no dvid or maybe a positive to add voltage dvid of +0.010v but make double sure the first two numbers are a 0 so not to overvolt the cpu and fry it

might need loadline calibration on high aswell

manually set the cpu/pcie clock to 100 aswell

Was browsing the web today and had a BSOD,
