Any more than that and you supposedly risk degradation if you run abnormal loading programs like IBT, LinX and Prime 95. Either way, we can fairly assertively state that if degradation doesn't scare you, the full load temperatures will. It’s not all doom and gloom though. Your average user should easily be able hit 4.5GHz with a tiny bit more voltage than stock, so the temperatures will be imminently manageable."

Thats a pretty dated article for ivy and no doubt influenced by the temps people were seeing at the time. If the chips were running as cool as ours they would have stated different vcore tolerances I am sure. It was a hate ivy bridge keep sandy fest in April.

TD,
Good job on your delidding thread, I hope you figure some things out when you get chance to test another chip in your mobo. Since you are good at doing informative threads, you could do one about your folding experience. I know there are newbs who know next to nothing about it.

Valgaur,
Thanks for adding me, and thank you again for a great thread.

Do you have to worry about scratching or damaging the die in anyway since most coolers have some play in them while installing?

Was it worth it? That's a very subjective question and I'm sure everyone will have a different opinion. The risks are high, but also the rewards. For someone doing it for the first time, be prepared that you may damage your chip and/or your motherboard. Keep in mind, that I had a very good chip to begin with.

direct die vs. delidded:
  • Did I see a performance difference at 0°C? No
  • Did I see a gain in MHz with ambient room temperatures of 20°C? Not really--not with VCore values that I feel comfortable with. Understand that I was already somewhat stable (I could run 10 passes of IBT) at 5.0GHz and 1.415V delidded.
  • Did I see a reduction in temperatures? Yes, My temperatures were reduced by about 7 to 8°C from my hottest core.
  • Was I able to reduce my VCore? Yes I was able to lower my VCore by 0.02V (5.0GHz with 1.395V)
  • So what is the benefit for me? SILENT COMPUTING! I'm sitting here typing this and all the while my processor is running at 5.0GHz. My fans are set to 6.7V and will only lift a sheet of paper by about 1/2 inch when laid over the radiator. AIDA 64 stability test has been running the last 10.5 hours and my average core temps are 56°C.
  • Was I worried about too much or too little pressure on the die? Absolutely, with no way to measure how much pressure I was putting on the die, I just had to guess and hope I didn't break something. My first boot attempt resulted in post code 55. I loosened my water block a little and this time the motherboard would not stay powered on. It turned out that I was being too conservative with the pressure I was putting on the die. I increased the amount of pressure until finally I could boot. Now that I know exactly how far to tighten my block, I am extremely comfortable removing and remounting the block. I have done this half a dozen times already.
  • Does it take nerves of steel? Yes

Does anyone know anything about overclocking the integrated graphics? (see sig rig:video editing build, worse 3570k than i even talked about, it binned worse, looking at 1.26v for 4.4, fail in 20 minutes on 4.5/1.32, msi g41, ares ram 2x2gb 1600 cl9 1.5v which seems okay at 2000 CL11 1t 1.65v, no gpu).

Does it affect cpu or ram stability? im assuming its just like assuming a graphics card - increase gpu voltage/frequency as necessary, make sure it passes 5 minutes of occt error testing and your good - but i dont know what voltages and frequencies to begin with or look at, and how it affects stability. this motherboard actually doesnt have igpu voltage, so... yea im curious what would be the frequency id be looking at, make sure that 5 min occt testing is the way to go, if it affects cpu stability at all.

thanks.

MikeG,
Thanks a lot, very good and detailed answer.
So for max temps while stress testing 5.0 at a CPU-Z voltage of 1.408 you have 70c? Is that correct, and what are your ambient temps?

It's funny you should ask. biggrin.gif Yes, I have experimented with overclocking my integrated graphics. I was able to get it working at 1500MHz (X30 multiplier), but not any higher. I was having so much fun overclocking that I set my CPU to 5.0GHz, my 16GB ram to 2400MHz, and my GPU to 1500MHz. I then started Prime 95 blend and Furmark. Not the smartest thing I've probably done. doh.gif My computer suddenly powered off, and I could not power it on anymore despite unplugging it and plugging it back in. It finally powered up again after several minutes.

certain wu's man. I get lucky with them a lot and they great me with respect back as well lol. but with the CPU and GPU thing. doesn't matter what one you get since they use different algorithms anyways. so I need to set my gpu as well. rolleyes.gif

Yes the temperature on core 1 spiked up to 70c at one point, but I'm not sure when that was. I could have been testing my GPU or loading an application. My average temps for the past 11.5hrs is 56c and AIDA 64 is still running.

When referring to "ambient" temps, are most people talking about the idle temperature of the CPU, the temperature within the case, or the ambient temperature of the room? The temperature of my room at desk level, and on the floor near the intake of my computer is 20.6c (69F) .
