Hi ppl!
I was just wondering how far could the I5 be pushed. I know that this kind of CPU are somewhat limited because of a factory thing, that they can't dissipate that all the heat. Nevertheless, how far could it go with a heatsink or a watercooler?
First of all it's a K version so it's better to Overclock.
How far u can push him? Depends on your self what cooling u have and how much u want him to go. Record is atm 7.18Ghz
I think u can easy get 4.5Ghz with water cooling running 50°C at stress test (100% CPU usage)
I own a 3570k and I also have a 200$ motherboard made for overclocking. I also have a really good air cooler, used top quality thermal compound, and have a really cool case. Not quite as good as an H100i water cooler but good enough to give you an estimate on the MAX you can get out of a 3570k.
I believe 4.5Ghz is the perfect overclock for these chips. Many people, including a friend of mine who has build 100's of these say the same thing. They kind of hit a "wall" after 4.5Ghz. They take a whole lot of voltage once you pass 4.5Ghz. Pretty much every chip. I've had 2 and they both acted the same.
I have mine clocked at 4.6 because I want to be better than average, but the bad part is that my chip gets up to 95c in Intel Burn In Test. Granted, in prime95 it only gets to 85c and during normal use I never even see 70c. Keep in mind 95c in IBT and 85c in prime95 are my MAX temps on my hottest core. That's not my average. My averages are probably 90c in IBT and 80c in prime95.
But the absolute MAX I believe these chips will go on air or high end water cooling is 4.8Ghz. As it takes damn near 1.40-1.45v to get to 4.8Ghz and to get the 5.0Ghz it'll probably take 1.55 which is over what Intel suggests. And that's a TON of voltage. So I think if you have one of THE best chips out there, you may be able to get 4.8Ghz with higher end water cooling. I've never heard of someone having their 3570k w/water cooler at 5.0Ghz or even 4.9Ghz. You just never hear of that. Although SOMETIMES you'll hear someone say they're at 4.8Ghz. But they may not even be completely stable or may not be cool enough. I THOUGHT I was at 4.8Ghz at one point but I quickly found out I wasn't stable and was too hot. I was also at 4.7Ghz for a while but it wasn't completely stable at the temps I wanted to be at. And now, at 4.6Ghz and I can say that I am completely stable after over 100 passes of IBT on very high and hours and hours of prime95. I've had this overclock for a while too and it never so much as hiccups. My voltage needs to be 1.370 though to be so stable.
Sometimes you see people who say, "yeah I'm at 4.5Ghz at only 1.20-1.25v". But I can promise you that if they were to run 100 passes of Intel Burn In Test on Very High, they would soon realize they weren't stable. Sure there are differences between chips, but not that much difference.
