Hello gentlemen! I am currently building my first gaming machine (never overclocked before and stuff like this :( ) and I would like to ask you how to overclock the Intel Core i5-3570K 3.40GHz (Ivybridge) to it's maximum performance and if the Corsair Hydro H100i is ok to cool down the big boy.

what board/memory are you using

psu: Corsair Enthusiast Series TX750M High Performance 750W '80 Plus Bronze' Modular Power Supply (CP-9020040-UK)

case: NZXT Phantom 410 Enthusiast Midi Tower Case - Black

gpu: MSI GeForce GTX 680 Lightning

cpu: intel core i5 3570K unlocked quad core

motherboard:Gigabyte Z77X-D3H Intel Z77 (Socket 1155) DDR3 Motherboard

ram: Crucial Ballistix Tactical Tracer O+B 8GB 2X4GB PC3-12800 DDR3

There you go mate , everything you can as for :D
 
im not used to that board but if its similar to the up4 th then you can set llc to high,cpu v to normal

pwm phase control to extreme,cpu voltage response to fast

cpu multi to 45 which is 4.5ghz

and set dvid dynamic voltage to +0.015v(may be able to use +0.010v) you would need to test

downlaod realtemp and keep temps below 80c if you can and keep vcpu voltage below 1.35v

downlaod cpu-z and check load cpu voltage while stressing in prime95/blend test
 
I own a Z77X-D3H too and could not overclock a 2500K successfully. It would not hold 4.2ghz stable without at least several boot failures a day. I can't say I am impressed with the board so far.

I hope it does better with a 3570K I'm looking at.
 
I've just manged to get my 3570k prime stable using large fft at 4.4Ghz using Vcore of 1.32.

That's set as 1.29 in Bios using Extreme LLC
 
Same combo as OP and I can't seem to get it to stay stable above 4.2 :/

All the volts in the world don't make any difference either, I think I'll give some of these settings a go. Do people leave speed-stepping enabled?

Edit: tried those settings, I've got dynamic voltage set to +0.040 for 4.2 :O blue screened with that at 4.5 before the windows bootscreen had finished.

try with a level higher llc and one/two clicks less dvid

so try turbo llc and +0.010v dvid,remember to keep an eye on load cpu temps/voltages

keep all power saving states enabled

set dram voltage according to your ram 1.55v ect
 
Hi there,

Could you please try these settings to get you started at 4.4ghz, this will more than likely use more volts than necessary but should work with any chip. You are then able to tweak from there.

Advanced Freq settings :

CPU turbo ratio: 44
Dram Freq: 1600

Advanced Mem settings:

Dram timing selectable: quick
Channel A timings: (8,8,8,24, command rate 2)

Advanced voltage Settings:

3d Power Control:

PWM Phase control: Exm Perf
CPU Voltage response : Fast
Vcore Loadline calibration: Turbo
CPU VTT Loadline (If you have this option): Turbo/+60%

CPU Core voltage control:

CPU Vcore: 1.3V

Dram Voltage control:

Dram Voltage CHA/B : 1.55v
Dram Voltage CHC/D (If you have this): 1.55v


Now if you save these your system should post just fine. Your chip however will most probably not need as much voltage as I have given it in these settings so you should be able to keep lowering the CPU Vcore/Loadline until it stays stable.
 
I'd try and use as little vcore as possible because each 0.005v Adds 6 degrees celcius to your temps when running Prime (especially with the New version of Prime) which makes stress testing a real pain!
 
Sorry to take over a little but you might find it helpful

I tried for days playing around with the voltages and today thought stuff it, turned them all back to Auto. The only settings I have done manually at the moment are LLC to Turbo, and DDR LLC to Turbo, everything else at the moment is set to Auto

Couldn't get it stable at 45 cores before, kept failing Prime Large FFT's but now no problem

I have installed Tweaklauncher as it is useful to see what the voltages are being set to by the board

Anyway here we are at the minute

Ive left everything on auto, set the multiplier to 45 and CPU PLL to 1.7 and I get a stable 4.5ghz @ 1.248 volts and 76C using Prime 95 with a Phanteks cooler.

Ive not touched any other settings, this is on a Z77-D3H btw.

Your vcore on auto?

Those temps and volts are questionable because they look like heading for the twilight zone once Prime kicks into full swing. As the image shows, Primes been running for just 1 minute,and already your max temp is 79c, and 1.380v for a 4.5 :eek: I'll stake my house that once Prime hits the next sequential test, you hit 95c or more!
 
For 4.5ghz you should need llc on high and dvid or offset set to +0.010v

I'm stable with medium llc and +0.010v which works out to 1.188v but each chip will be different regarding how much voltage it needs
 
1.188 under load?

It will be stable lower than it is atm. I was manually setting the voltages before and was around the 1.29 area and it was still failing prime large ffts

Looks like you owe me a house ;)

Mine after 10 mins of prime, Ive also got 2 other computers running Q6600's that are overclocked in the more traditional way but for some reason this i5 with this motherboard has overclocked very easily on auto ?

If I go any higher the voltage ramps up and things go into meltdown but Im happy with 4.5 as it is.
