Just recently moved across to the darkside,3570k with a gigabyte z77 d3h motherboard.Havnt had much time to mess around,but i have got to 4.4ghz stable (ish)at 64*c,my core voltage is 1.25,and the only other adjustment i made was v core llc to turbo.when im at idle frequency goes down to 1.6 but voltage stays the same according to cpuz,however in core temp vid says it is lowering,which one is these to monitors is the most reliable or is it something to do with llc,defeats the object if the voltage is staying high
 
You might want to wait for a second opinion but I think CPU-Z reads the VTT(?) voltage by mistake on Gigabyte boards, it used to on the P67/H67 ones anyway...

What is your voltage showing as in CPU-Z?

Also, using a manual voltage might cause the power saving not to work, I think you have to use offset instead.

just posted in another thread about CPU-Z not showing downlocking speed in 1.62 version, i went back to 1.61 after checking it with another bench and everything went back to normal!!!


so cpuz 1.62 is bugged (at least for me) 2600k/asus p8p67 evo
 
Thanks for the info,tink i got other bios issues at the moment,the voltage issue appears to be ok now,think i need to look into o/c guides for my gig z77 as im not 100% on what im doing!!!!
 
ok thanks for that,i found something similiar on that site,i have been messing about in my bios and got to fairly stable 4.5ghztested for an hour at 74*c,but my voltage was at 1.32,any thin i can do to lower this? as i been trying a few different setting,still struggling a bit with settings not sure about

im on almost identical set up i think your voltage is a bit high run drop a little keep trying .

im stedily doing it when not gaming 4.3 2 days solid @ 1.260v temps in game reach 57c bench mark ibt maxxed reach 70c
 
i managed to get the frequency lower in idle, i adjusted windows power otions,but hwmonitor also says voltage is still 1.32,i tried lowering the cpu voltage in windows advanced power options,but not sure i was doing it right
 
Go into BIOS, disable EIST and C3/C6 states. Leave C1E enabled, it will downclock to 1600MHz and lower voltage to around 0.90v idle. When loading it will vary from 3400 to whatever your max turbo core is set at.

If you use turbo cores to overclock it's easy to use C1E with offset voltage enabled. I find this superior to EIST.

I use +0.005 offset with Turbo LLC on my Gigabyte board for 3570K at 4.5GHz. Idle 0.88V load 1.25V.
 
ok,been messing with power settings,keep getting the odd blue screen and mouse freezing,seems it happens when im adjusting any think to do with power,happens in both bios and windows,think i might have to reset everything ive set in the bios and start again,i will reset to turbo llc again(i dropped it down to medium)what setting is the offset voltage (sorry for being thick)
 
I didn't have a clue how to overclock my Ivy after being on my Q6600. I learned from this forum.

Find the CPU Vcore option, if it is set to AUTO select "Normal" then it should unlock a voltage option underneath which is the offset. At 0.000V offset it will run pretty much at the voltage the CPU think's it needs (which may be too much or not enough). You will need to adjust offset and load line calibration to achieve the right VCore at load. Try start with Extreme and +0.000V offset.

For me +0.005V is about right, with turbo vcore, gives me stability at idle and load.

At stock, what voltage does your CPU have?
 
i wondered why that was greyed out,thanks for that,i will do that later on as im away from my desk top at the moment,i feel like i might be getting somewhere now,thanks for the help
ps,i have a gelid heat spreader,once i get this stable i think i will attempt a delid!!!
 
Delid is quite risky in my opinion, I lost my first 3570K because I cut into the PCB. The gelid heatspreader is good but I can't guarantee it works on more than 1 chip. :)

I'm wondering it it's worth the 9-10c temp drop since it cost me £170. :) 4.5Ghz was fine without delidding for me, I just couldn't resist doing it after failing my first attempt.
 
ok i will think about that,i still got some problems,however my voltage and frequency drop down fine now thanks,but im stressing at the moment and my voltage seems too high,4.5 was 1.38v,temps were about 74*c,how do i get the voltage down,is setting the offset up the answer,i got it 0.000 at the moment,c1e and speedstep i set to auto,
 
No it'll b ok enabled,you just need to lower your CPU voltage by either using a lower loadline calibration llc level or using less dvid,you can undervolt the CPU by using minus - dvid amount
 
ok,im set at 4.4ghz,llc is on high,and offset -0.005,the voltage is 1.35 so its quite high still,how low can i go on dvid? at least everythink goes low when at idle
 
as low as you like,untill it crashes

you can use medium llc(what im using) and +0.0010v see what that gives you at load,if its too much come down on dvid use minus or keep it as it is now(-0.005v and just lower the llc

why 4.4ghz? and not 4.5ghz?

you just need to fine tune llc and dvid,each cpu will be different in how much voltage it needs or doesnt need ect
