Didn't get around to overclocking it yet anyway, will post max clock when i do though.

In terms of OCing performance they are pretty on par with each other however Ivy Bridge chips run hotter as you up the voltage because Intel decided to use TIM between the die and IHS instead of soldering it like the Sandy Bridge chips. Therefore you will usually hit your temperature limits well before you reach your voltage limits with Ivy Bridge chips. This is why many of us choose to delid them to fix this temperature issue. Also keep in mind that idle temperatures (I'm assuming those are idle temps you posted) mean absolutely nothing. All that matters are your loading temps when running a program like Intel Burn Test or Prime95.

Yea idle temperatures, under load about 64 degrees at 4.8 and 86 degrees at 5.1, though this is with fans on what i would call stealth mode, 95 degrees at 5.2 with fans turned up about 50% by the way =)

However i thankfully don't full load the CPU 24/7, overclocking is just a interest not for a real performance gain, though i do appreciate the faster video encoding times.

Thanks for the input though.

I left it prime running with the settings suggested in this tutorial for just over 7 hours and still returned no errors biggrin.gif I'll try as you suggested and go for 90% of ram and see if it's still stable. My first overclock was going for 4.6 but I couldn't get prime to last over an hour without an error unless I Put enough voltage in, and with the extra voltage came extra heat. I'm going to try again and see if I can get it stable on a lower voltage, if I can't I'll just have to leave it until I get a better heatsink.

Yea heat is usually what holds back IB chips before you ever reach your voltage limit. That's why I delid, my 3770K dropped 28C after delidding it and I expect about the same from this 3570K this weekend biggrin.gif.

Great guide. Thanks.

I have the bios configured to the guide and I've got my 3770k stable at 4.5GHz with offset +0.005v and turbo boost +0.004v. My maximum temperature during a 1 hour prime test is 75 degrees C and vcore is 1.208v. I tried to increase the multiplier to 46 but it crashed. I tried to increase the boost by 1 spot and it still crashed. Before I go any further what is the limit of the turbo boost?

I'm confused now. I've got an i5--3570k (mostly) stable at 4.5ghz. Core voltage in CPU-z says 1.128v. I've got offset at +0.005 and turbo boost voltage to +0.031. Does this mean that turbo boost isn't engaging?

i leave my turbo at +0.04 and raise the offset and LLc to oc past 4.6ghz .

New lowest voltage @ 4.2ghz

CPU Core Voltage Offset: -0.015V
Additional Turbo Voltage: +0.004V
Load Line: Level 5

IBT Running:



(does anyone know why CoreTemp shows some crazy numbers for its Power reading?)


IBT Completed:




I wonder how much lower I can go?

If you're stable at 4.5GHz, then your turbo boost is engaging. Unless you've disengaged speedstep and are running constantly at 4.5GHz. I mean, I guess that's how it works. On my cpu, the max default turbo boost speed is 3.7GHz, but when I put any stress on the cpu, it goes from a low idle speed (I do not have speedstep disabled) and bumps up to 4.5GHz and remains there as my OC. I've tried to go higher, but 4.5GHz seems to be my sweet spot.

maybe yours is glitched and has a 1 in front of it
offset -0.030v
turbo 0.04
LLC level 5
