Just been having a play and seem to be bale to get a stable 4.5Ghz over at 1.35v.
Tried to get it stable at 4.6 and its seem to only be stable at 1.41v.

Bios setting i have left everything default apart from the core voltage and the turbo clock speeds.

Please resize image to a maximum 1280 pixels wide.

At 1.41v (cpuz shows it at 1.428v) temps are below 85 degs but after looking at other peoples overclocks 1.42v seems to be way too much.

Is voltage not an issue as long as you can keep temps down?

Are they other setting i should be changing in bios that would enable me to get voltage down and still be stable?

I have read quite a few guides but as being a newbie to overclocking im struggling to get my head around them

Cheers
 
That is far too high for my liking on the voltage. What is the VID of your 3570k? Mine is 1.1950V and is stable at 1.28V under load for 4.5GHz. Those are air temps right?

Voltage is an issue for long term use as far as I am concerned. I would rather keep my 3570K under 1.3V for long term use, but I'm not actually sure what the intel limit is for the chip. Ivy really heats up with voltage. Your temps seem good for that much voltage it's a shame for it to run so high.

Have you tried just leaving everything on auto except the CPU multi? I doubt your board would give it that much voltage, more likely to be around 1.34V (AUTO) for 4.5 but depends on your chip.

Try VTT at 1.080-1.100V and PLL should be at 1.650V-1.800V for that speed really.

Download HWMonitor and check out your motherboard pwm temps etc at that voltage, you might be shocked.
 
Just to give you an idea of another guys settings:

CPU/PWM voltage settings:

  • VCore - Normal
  • DVID Offset - +0.060V (try +0.100V at first and check stability)
  • VTT - 1.050V (I only raise this to 1.080-1.100V if I have my ram overclocked, currently it's at stock)
  • PLL - 1.650V (1.800V Default)
  • Load Line Calibration - Medium (Try on Extreme first, adjust to lower the load voltage, it's about 0.01-0.02V per step for me.
  • Turbo Voltage response - Fast (Auto sets to fast anyway)


CPU Frequency Settings:

  • CPU Multi - 34 (stock)
  • CPU Turbo - All cores set to 45
  • Thermal Monitor disabled but doesn't matter
 
Be sure to check your PWM temps, mine are 60c max but if I up voltage they can really get hotter, and this is with UP4TH, I think D3H has no mosfet cooling too don't want them to overheat.

How long have you had this i3570K, if mine needed this much voltage for 4.5 I would send it back and hope for a better one. 1.39V is quite bad for 4.5.

What voltage does it say your chip is at stock? I started using manual stock voltage, and raised the multi until it was unstable, then I added volts and multiplier to find my 4.5Ghz voltage.
 
im guessing the pwm temp is the 3rd one down under the list of the motherboard temps as its the only one that rasied when underload. If so it went upto approx 60-61 degs.
chips is 5-6 week old
 
just reset cmos to see what stock voltage is. Board is setting it at 1.225v under full load.
Tried using the setting that you posted but must be using differnt board. Seems like on this board DVID is locked? it wont let me change the value or is there something i need to enable or disable to unlock this feature.
seems also that i cannot change turbo voltage responce or i just cant find it in bios. Only one listed is vcore voltage responce.

I know all about silicone lottery but how unlucky do you have to be to get a chip this bad lol.

o.k
iv reset cmos
set turbo to 45 on all 4 cores
set PPL to 1.65v
vcore volts set to auto
load line calibration medium
vcore voltage responce fast

its auto setting voltage to 1.365v
max temps are 72 79 80 77 after 10 mins
 
VCore voltage response is what I meant sorry. It seems to be .250 or so higher than my cpu, maybe go for a 4.4Ghz overclock for now? I think I will go back to 4.2 as my 4.5 is being a pain and I don't need 4.5 right now.

DVID will be locked unless you select "Normal" as the CPU Voltage. I am not enjoying overclocking via this offset/turbo method.
 
Okay, nice. Download Gigabyte's 3D power from your motherboards web page. Inside this is setting to change the LLC in windows. You can lower it from there and see if it's still stable while it is stressing.
 
Seems vcore voltage on auto is now a little lower just trying it on 4.6Ghz turbo with same settings.
auto vcore voltage is sitting at 1.416v
PWM temps max is 68 degs
CPU temp max is 77 85 87 81
 
Too high for my liking, I like to keep mine under 75C in Prime95 unless using IBT then I don't mind 85C.

I wouldn't want to go higher than 1.35V on air. Even my Q6600 didn't need that much juice.

I've just given up trying to get stable at 4.5V using offset voltage. Instead I'm just clocking at 4.2GHz. 4.2 can be achieved by setting bios defaults and just changing the multi or turbo to 42.

What do you use your CPU for by the way mate?
 
It depends, all motherboards I've used will use too much voltage on Auto setting. Just an easy way to see if your CPU can be clocked to those speeds.

I recommend lowering the voltage manually with a set voltage ulti you find stability. I reckon 4.5GHz would be anywhere from 1.32-1.38V (at 100% load) for your CPU. Keep LLC at turbo/extreme so you can lower it for testing voltages. VTT at 1.100 and PLL at 1.800 for now just to rule them out as a cause for instability.

I'll check back after some games good luck.
 
Think iv found my comfortable limit.
turbo 4.4Ghz
vcore voltage 1.35v
Max core temp 75 degs
PWM max temp is at 65 degs
Seems stable after 15 mins but will leave prime running over night.

Will this be ok to use 24/7 as long as stable overnight?

Only just seen your post about what i use it for, Mainly gaming.

Thanks again mate
 
Have you tried lowering the voltage any more than that? I think it's safe personally, but I've found it so hard to find actual legitimate information on the safe Vcore for this CPU.

During gaming you won't reach anywhere near 75C which to me means that 1.35V should be fine.

Try also 5 runs of IBT on Very High setting, I've been told here that this is also a good test.

I use Prime95, but IBT is much harsher and I use that first sometimes it will show unstable even though Prime is.

You are welcome! Wish I had more knowledge.
 
yea i`ll give IBT a go and see what happens. I have read in a few places though that using IBT is unrealistic because it is so harse you will never come anywhere near the limits it tests to.

Iv also read AIDA64 is supposed to good also which is what iv just been using just to do a quick check to get an idea of temps etc.
 
You have one thirsty chip! I like AIDA64 also. Prime defo my favourite though. I'm beginning to think mine needs 1.3V at 4.5GHz, so yours isn't doing too badly really. Atleast temps are good, hope it stays stable for ya.
