***Official Ivybridge Overclock Thread***

lol - I know that as I can be one of them :)
The list would be very long, and possibly endless, littered with my impulsive type buys. But I can always afford to with spare cash and understand the potentials. I'm just hoping that Ollie to can both afford and understand that things can, and sometimes do, go wrong.

I have just bought on of the DGM 27" monitors. Did I need it, no as I my 24" Dell was running great. But it does look good, albeit it cost me £320 to get that feeling :D

So you would do all of that for the sake of around 200mhz which in real term usage would mean so very little..?
If it is important to you then go for it but remember the risks and if you think that yours is the worse chip possible you might end up being very disappointed with what you but next. It is often the luck of the draw.

Not for the sake of 200mhz. For the sake of temps less than cpu shutdown point. I quite like my overclock speed in all honesty and if I did flip the lid/change my CPU I would probably stay at the same speed. I might change my mind when I get back down to England and it's no longer "summer" will probably do what eyetrip said. Seems that i7's on a famous site are being flogged £40 less than what they should be going for as new. I got mine for £220 off OCUk when they were first released. And I would really rather not part with it for less than £200.

Even though you have 4.5Ghz in your sig are you saying that even with that overclock and your cooling that you still get to the TJ Max and thus the CPU starts to throttle...?

If so what sort of offset voltage do you have to use and what cooler have you...? Is the cooler the K2 in your sig..?
 
It is indeed the K2 in my sig. I don't use offset haven't messed with that yet. I just use LLC at 1 with a fixed voltage of the lowest possible for my OC. And yes I am saying I hit 105C (CPU doesn't throttle at this point just shuts down entirely)
 
My 3570k would overheat more when overclocked using that type of voltage control than it does when using...

All the turbo functions on - so it will vary from 1.6 to 4.4Ghz
Multiplier set to 44
LLC set to Normal
Offset voltage set to 0.05v

That will set it to approx 1.236v for the 4.4Ghz overclock, but throttle down the voltage when running at lower than 4.4Ghz.

I do not touch the vCore voltage per se as doing that and adjusting the LLC too "aggressively" can seem to over volt and thus overheat my chip.

I also use a very cheap Arctic Freezer rev 2 cooler and it stays around 75c max in a warm room when under full load.

You might want to rethink how you are overclocking..?

Just a thought and it might not make a difference for you but it could help :)
 
So if your uses 1.23v under full load of 4.5Ghz and you have "adequate" cooling which is working correctly I would not know why you get temps exceeding the TJ Max. It doesn't seem to make much sense, providing that both the HSF and TIM are appropriately applied. The case and room temps I assume are reasonable...?

Has me puzzled too.
Touch the heatsink while its under load, if its cool enough to touch at those temperatures you listed, its not seated correctly.

From my experience this is the crux of the IB problem. I was getting very high temps reported in windows, but the heatsink was cool to the touch. That was until I removed the IHS and replaced the TIM.

I think there is another element to removing the IHS other tham just the TIM. When I took off the IHS i also removed all the black silicon glue, so when I re-installed with the IHS just placed on the CPU and new TIM it will have sat slightly lower onto the silicon. We are only talking a tiny bit, but I think that maybe there is not enough pressure on the silicon and therefore the heat stays in the core rather than transfering into the IHS.

A standard chip with the IHS un-altered just does not pass the heat through the IHS and that is why we see such high temps.

These are just my thoughts from my experience.

Before removing the IHS i put a temp probe onto the side of the IHS while the PC was running prime. When windows reported the CPU temp at 80-90c my probe reported about 50c.... so it is not always a case of the Heatsink not being mounted properly.

@Simon - I did the same as you when I removed the IHS, I also cleaned off the rather thickly applied black sealant. Using the liquid metal as the TIM and possibly the scraping off of the sealant reduced my temps by 15c.
 
around 30 all cores Idle, 58 max at 4.5. Under water. Thats general use though dunno what its like under prime ibt etc prob double the temps lol.

I was going to remount and apply mx-2 to compare against noctua nth1, and when I had everything apart, decided I would have a look at flipping the lid.

Thought I would get an idea on how hard it would be, but the lid is down pretty tight, and was absolutely sure I would either do damage to myself or the chip, so decided I am not going to go down that route.

Am quite happy to run the chip hot. If it dies in 3 years, I will get it replaced.

104.9 degrees for you sir? ;)

thats cool thats what im getting with the stock cooler :) i was a little worried they were too high and i would have to reseat it, im waiting till my prodigy case arrives to put on my h80, hopefully temps will be better :)
 
I idle at about 35-45C currently (my computers in the kitchen and its quite hot here at the moment) My heatsink is seated correctly I've reseated it twice. But I'll reseat it again at the weekend just for the hell of it.
