Hi guys, hope no one minds me asking for opinions on such a basic level?

I'm not an overclocker, but i would like to squeeze a little extra 'value for money' out of my 3570k - even if it's just psychological :D

I've tried to very basic ways to up the speed. These are 1. Simply just increasing the multiplier to x40 in the bios. 2. Using the "optimized CPU OC setting" and increasing the turbo to 4Ghz.

I then ran cinebench to give my some figures, to see if there is any improvement.

As i know zero about overclocking, voltages etc, I have posted some results below and would be extremely grateful if anyone can tell me if anything is good? bad? etc. I'd prefer not to mess with too many settings in my bios as my head starts to hurt!

I also used realtemp for temps, cpuz for info, and intelburn on standard to stress my system.

My system is: 3570k, asus extreme6 Z77, 8gb Corsair vengeance 1600mhz, 9,9,9,24 ram.

Cheers guys!

Set voltage 1.3 multi to 45

Loadline calibration to max

and test.

If stable gradually reduce voltage untill it isnt stable anymore and then add a touch more. I.e if it crashes at 1.28v but was stable before set to 1.29 and try Again.

Thats a very simplified way of overclocking. I found my old 3570k made 4.7ghz @ 1.32v
 
Monitor how your voltage changes under load. Sometimes at max load line calibration the voltage increases massively when you push the CPU.

And watch temps.
 
Thanks for all your suggestions guys.... Before i posted the question i thought "right, i'm not going to get too into this i just want a simple little boost", Now you lot have currupted me with your evil ways and i want to start tinkering more lol ;)

ok, so.....


i've left most things as they are, except....

I've set clock multiplier at x40 for now ;)
Changed my LLC from auto to 5.
changed voltage from auto to offest-0.065

the pc runs stable, gaming and using intelburn, and gives the following results

Idle
volts: 0.776v, temps 28c

Stressed
1.080v, temps 52c

So, does that look.. erm ok??? what should i try next?

Ideally, I'd like the pc to increase to 4.2ghz max when under load and then drop when idol. I'd also like the volts to drop when idle as well to eaze stress on the cpu. Is this possible? and can i still expect my cpu to last a few more years?

Sorry - This really is new and confusing ground for me.... one that i vowed I would never explore! such is life!!! Thanks :)
 
idle and load voltages are really low. im surprised youve not had crashes and doubt you can overclock higher without reducing that huge minus offset.

what cooler do you have?
 
It's interesting you said that, as I just tried x42 multiplier and it crashed.

I'm running a custom water cooled loop with a double radiator and push/pull fans. I delidded my cpu, but it's still running hot I think. It's my fault as I put normal thermal paste between the die and the cover. I've just ordered some of that coollaboratory liquid ultra, which i'm hoping will improve things.

Ok, so now i am addicted to tweaking....

I've left everything in my Asrock extreme6 on auto, except for....

mulitiplier x40
additional turbo voltage: 0.004v
cpu voltage: offset mode
offset voltage: -00.050v
LLC level5

this gave me....

Idle 0.800v
Stressed 1.112v

Do these figures seem safe? and should i leave it as it is - but push the multiplier to 42 now?
 
With a custom loop and delidded CPU you should be fine for up to 1.4v. Just keep the cpu under 80 under benching. I would just do a quick overclock like Noobcannon says and save some time, bang it up to 1.3v and 44 multi, then try 45 etc.

If you think your getting bad contact after you delidded make sure you check all teh cores temps seperately as one might be running a lot hotter than the rest.
 
I know this is a stupid question (but asking anyway lol), when you say - set voltage to 1.3v, does that mean, i change from "offset mode" to "fixed", and then enter 1.3v in the option that appears below?

it was hitting 84c at 4ghz 1.2v, i dont think setting to 1.3v is a good idea untill you change that paste.

stick with offset mode, then when the cpu is idle it will not be stuck on a high voltage for no reason.

you can try x42 and if you get a BSOD during prime95 small FTT test, increase the voltage by 0.005 or 0.01
 
so, am I right in thinking that the larger the (-)offset, the more the cpu voltage will drop when idol?

yes at idle and turbo it will undervolt.
though really you shouldnt be on such a big minus offset for overclocking. you'll need the stock vcore and then some on top as you increase the cpu speed further
 
Cheers for that, I'll reduce it a bit then.

Sorry for more questions.. I get that LLC reduces how much the voltage droops under load, but in this bios..... is 1 the highest as it looks like it stops the droop completely? whereas 5 is the lowest and allows some?

i thought 1 must be the high setting and 5 lowest as when i use medium llc on my board it increased my vcore by about 0.05, high increased it more, extreme no doubt it would increase again.

maybe google how the llc works on your board ? since it may just hold the voltage better or give an increase
 
I've just had another tinker - and yes, i need to sort out the thermal issue! i set everything to default except for x40 multiplier and ran intelburn.

Voltage went from .8 to 1.2 which is ok, but one of the cores shot up to 93c!!!

Hopefully my liquid ultra should arrive in the next couple of days so I think i'll behave till then
 
WOW! I put the liquid ultra under the lid, and Noctua between the lid and cooler.

I haven't overclocked yet but its a huge 38c cooler under load!!!
 
Ok, I've tried 2 mild overclocks x40 and x42, and they are 100% stable in both tests and real world use. I've set LLC to max, turbo to +.004, and voltage offset mode to -0.050.

I then tried upping the multiplier to x44 and it blue screened shortly after bootup.

Any ideas what I should try to stabilize it?

Thanks again for all the help. I've included my existing results below if they help?



x40 Idle
Temps: 26,24,30,24
Voltage: 0.792V

X40 Load
Temps: 42,46,47,44
Voltage: 1.176V


x42 Idle
Temps: 26,25,30,25
Voltage: 0.792v

x42 Load
Temps: 46,48,51,46
Voltage: 1.184V
 
needs more voltage. try changing to offset mode -0.025 if it bsod's in p95 small ftt, add more vcore.

Not sure if my CPU is freaky or the Gigabyte mobo (Z77x-UD3H) is helping but with no changes just setting the turbo multiplier I get up to 4.4 GHz and mid 50 DegC on air.

The voltage is set to 1.3v+ so I can manually set that to 1.18v and the temps don't go above 52 DegC at 4.5 GHz running Prime95.

I need to work which opyions will lower that at idle.

Thanks, I ended up having to reduce the offset all the way down to -0.010 and it seems rock solid now with the following results.

Idle voltage: 0.832, load voltage: 1.240, and the maximum core temp it reached was 55 briefly.

Would this be ok to leave as a permanent overclock without noticeably reducing my cpu life?
