|
 |
Hmmm ok so i did a vcore offset setting with the boost volt on the smallest increase, just like that famous guide online said. This is pretty much stock voltages etc, and i just upped the multiplier to 38 to reach 3.8 and did another test with 40 to reach 4.0 ghz
But im getting very high temps when stress testing with Prime95, im getting to the 85s and after some minutes hitting the 90s. ON both 3.8 and 4.0, let alone 4.0+
This is on the stock cooler, an Asrock Extreme4 and i changed the paste to AS5 and still the same results.
I thought this i was supposed to be a great OCer cpu, or is it the stock cooler? Hope i didnt get a bad chip or something...

Of course it's the stock cooler. Those things are not made for custom Vcores and overclocks.

Are you certain? Most modern Intel CPU's downclock to something like 1.6GHz when idling as well as dropping vcpre. You either had to disable every single power saving thing in the UEFI or you've locked voltage and CPU speed (well, both are the same thing).

oh right, forgot it might idle at lower ghz 
i dont have access to my pc atm so im not so sure about my temps anymore. I think they were max 60 or so under load. I changed tons of stuff in bios so no clue what it is in idle tbh.

Didn't you just buy it? Why would you want to overclock it? Speed is more than enough for 99,9999% of the games.

There's those of you who have hardware that's just enough
Then there's those of us who are enthusiasts and push everything as far as we can. |

Why not OC it if it's easy and stable?

The issue with Ivy Bridges aren't the CPU silicon itself, it's the cheap bonding Intel used between CPU and heat casing on the Ivy's. I hope they learnt their lesson for the next gen.

Yes i know. But even when de-lidded it generates more heat than SB.

Did you try lowering the voltage? What is the vcore at? If its at automatic, it will definitely be pumping more voltage than the CPU needs.

When ocing to 3.8ghz i get 1.200, 1.208 max, and temps go to 85 fast and they start rising slowly to the 90+

Friend has PC with 3570K and True Spirit 120, things get still very hot. I would recommend something like silver arrow or closed watercooling for Ivy if you are on budget (Antec 620 is pretty cheap and good with 2x gentle typhoons).
@Lopin18
3.8Ghz is the default turbo , should run much lesser volts than 1.2v, unless yors is world crappiest Ivy chip in the world. I would try with new cooler something like 1.2v - 1.25v and 4.5Ghz clocks.

I have an Arctic i30 with a 3570K, at full load on 4.6Ghz it hits 69 degrees. Keep in mind that the 3570 is faster than the 2500 clock per clock. So a 3570 at 4.6 will be equal to a 2500 at 4.9-5 Ghz.
Don't forget to disable the iGPU.

Ivy is about 200mhz ahead of SB at same clocks, not 300-400mhz. Its 2-5% faster clock vs clock, in like 99% of tests what i have seen.

I have read many reviews before buying, it averages at ~300Mhz.

Yeah, ok I understand that, but IMO it's silly to overclock new hardware if you are low on cash. Not sure how significant this is to the electricity bill 
But well, I think he just have to be patient till his GFX arrives. Good luck with the overclocking if you are not  |
Why's it silly to OC new hardware? Cash has nothing to do with it. If you do your reviews and research before hand to know your max safe voltages and safe temps, you have nothing to worry about. The myths of decreasing it's life are BS. Ya it will reduce the life but CPU's usually have about a 15+ year life expectancy. It's said you'll get 6+ years out of a 24/7 OC'd chip and by the time he even gets to 6 years, the chances of an upgrade are more than likely anyways.
Back on topic, I found the guide for you over on overclock.net Enjoy
http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition
Max temp for ivy bridge looks to be 105C but that isn't to say you should push it that high. The corsair hydro series coolers are great and pretty affordable. I paid 60 bucks for my H50 and still have it and still doing a great job. |

Yeah thats the guide i followed, thats why i was Ehhhh wtf, it should be working why is this thing melting.
Ill get an air cooler probably that Cooler Master Evo thing.

Agreed. Sounds like a lot of voltage for 3.8 ghz. But each chip is different and i've no experience OC'ing i7s.
At 4.2 ghz and 1.1vcore my 3570K stays around 52-53 degrees C doing intel's torture test on max settings with my coolermaster hyper212 plus. I havent tried to push it further than that since i dont see much point in it, besides the fun of tweaking your bios. Plus they are 10% faster than Sandy clock for clock. Pretty happy with ivy bridge... though i gotta say if sandy was cheaper than Ivy, i'd have bought one instead.

so, saw that stuff about the bad thermal paste used in the IHS on the ivy, so i figured, lets give it a try and remove it. But once i took the cpu out, it didn't really looked like its possible to take it off. I mean, the IHS is really REALLY close to the PCB of the chip and its like cutting into the plastic more then anything. So i dropped it and put it back in and while i was at it, i added a second fan to my 212, so now it has push and pull air. Thing is, there certainly is a big difference in temps between the cores. Core0 is the coolest, now in idle, its 21C. Core1 is 32, Core3 25 and Core3 32 ... and under prime95, its pretty much the same difference.
So i was wondering. Is it possible, that intel started to solder the IHS on newer batches of the 3750k maybe ? Or did i just not try good enough, to remove it?
Btw, i have it run at 4.4ghz now, at 1.225V and in prime it hardly goes over 70.

All times are GMT + 1 Hour |
. ofc there are golden chips which overclocks nicely with low voltage, but those are very rare.
