turbo disabled

all other settings auto

Are my temps ok? I see a difference between cpu core max (69) and cpu package (76). Which is the most accurate?
ambient temperature 27 celsius.

Package temp will be the same as the highest single core. Your temps are very good, but IMO, those are rather odd OC settings. If they work, then cool. Nice job!
For more MHz:
Why disable turbo? Enable it, set bclk to 100, spreadspectrum off, iPLL off, offset to +5, turbo to +4-10, LLC 3, only C1E enabled, all other sleep states off, multi to 43.
Push that puppy a litle more... This is the OC Net afte all smile.gif
I easily had 45x at 5/20 mV on my 3770k using the stock cooler! Temps <85C with IBT or p95.

Thanks for your answer! Package temp is 7 degrees higher than the hottest core. Sensor bug or hwinfo 64 bug?
Yes, these settings work, no instability or other issues (intel burn test vey high passed, bf3, x264 bench etc etc).
I guess you mean this is a good first step, right?

I dont believe I can reach 45x-normal temps using 412S under these circumstances (greek summer = very high ambient temp) smile.gif
For current settings, should I disable PLL internal?

For 4.5 you should have PLL overvoltage disabled anyway. I've only needed it for 4.6+ and the guide says 4.7.

As for the package temp, maybe try another program to see what it shows you. Make sure the remove the current program you have so the sensors don't show crazy reportings.

As for my issue where programs told me I was hitting 100C (no joke), it's seem to have either gone away or maybe this is the one time it wasn't reporting bogus temps for me. I'll do some more tests today to show you guys what I mean.

iPLL off might lower temps a little, but not much. I think that with the cooler you have, 45 should be fine if you do not overvolt it and tune in on the optimal vcore patiently. save the settings you have to a bios slot... then try the settings I recommended. 4.5GHz is not far away from where you asre and I bet that cooler can do it (use a good TIM like PK-1 or HeGrease, or Gelid extreme).

one thing about that board, it will overvolt thechip by 30-50mV compared to CPUZ. Be sure to use LLC3.

Hey guys, so basically I've got a 3570k running at 4.5Ghz, +35 offset, +.04 turbo, spread off, iPPL off, vcore flux between 1.176 and 1.84, max temps are 70C and it seems quite stable. Cooling is a h100i with noctua fans all around. Any suggestions to get up to about 4.8~, I'm getting constant BSODs even when I ramp up the offset. Yes I am completely new and have very little knowledge.

hats your idle vcore w/ the +0.035 offset? When you raise offset you increase your idle voltage. Usually you want to have your offset low +0.005 or so and then increase addition turbo voltage to stabilize your full load.

0.96 - 1.048V, I've lowered offset to +5 and upped turbo to +.08, load vcore is 1.160v with temps around the 65c mark now. Idle vcore is around the same though.

unfortunately getting 48x on an ivy will likely require delidding the cpu. Intel used a poor tim between the die and IHS therefore the processor can not loose the heat quick enough. it's not hard - many have done it either with a razor blade or the vise/hammer (I've used both and the non-razor method is sooo easy).

http://www.overclock.net/t/1376206/how-to-delid-your-ivy-bridge-cpu-with-out-a-razor-blade

as lucky is saying, you might want to flip your OC strategy and put 5mV in offset approx. 30 or soin turbo, LLC at 3, iPLL off etc according to the guide on pg 1...

you may get 45-46 with the H100, but 47-48 will require ~ 1.25-1.3x volts and it just can't shed the heat as is.

Ok thats a good idle but Ivy can usually go lower. I would try a +0.005 and increase you turbo past the +0.004 where its at now to stabilize.

Basically if you were going to try and stabilize 4.8 or even adjust your 4.5ghz OC, you would first find the idle vcore you want using the correct offset. After that you don't touch offset anymore, only additional turbo voltage to increase voltage at full load.

EDIT: As JPMboy said 4.8 is a little difficult on Ivy due to temps so might want to take a look at the deliding thread if thats something you are comfortable doing

I've confirmed stability after two 20 min prime95 runs, it's the weekend and I don't have time to complete a 24 hour prime test, I will when I go back to work. I'm sitting at 0.05+ offset, LLC at 3, iPLL off and turbo at +0.08. I was looking at deliding and might do that when Summer comes around as it runs at max 65c which is a temp I'm quite happy with.
