Overclocking my 3570K

post #1 of 16
Thread Starter 
This is my 1st built computer, an my 2nd attempt at overclocking.
Specs: 3570K
Asrock fatality professional
8gb ram (2x4gb 1600mhz)
Asus 7970
Hyper 212 evo cooler

Current settings: multiplier 45x, Vcore 1.2v, LLC level 1. Intel speedstep and powersaving disabled. All other settings are auto/default.
Been running prime95 for last 5 hours without a issue. Max temps 68, 72, 70, 70.

Questions: How long to run prime for before declaring victory?
Temps-varied between 54-70c (averaged around mid/low 60s), is this normal? Should I try reseat cooler? Idle temps seem to be about 12-14c above ambient...?
This should be fairly safe overclock? The volts seem quite low compared to sum I've read?

Thank you all-it's been thru this forum that I've learned from building to now overclocking, and constantly tempting to empty my bank account for new bits....

That sounds like a rocking setup. 5 hours is good, but most will suggest 12. I'd say go for 6-7 and call it a day (or do 12 if you want, I just never have time to do 12 and I never leave my computer on when I'm out or even asleep biggrin.gif )

70C on a 212 EVO is great. Mine hit 76C max. Stay under 80C (85C if you must) and you'll be fine.

Your voltage is fine. Some are luckier than others and you are a winner of the silicon lottery.

Have fun thumb.gif

45 at 1.2v is good, temps are ok.
5 hours is enough, though you can go the full 12.

Thank you both. I'm pretty happy with it, just wasn't sure if that sort variation in temp was normal. I'll leave it run awhile longer then try get a screenshot to post.

Prime should not be what is used to declare victory. You need to use the system for real world applications. I never got errors in Prime when testing, yet I would get crashes gaming, this was during voltage testing. Prime is just one thing you use to test with.

While I do agree that real world testing is good, Prime95 is still accurate and less tedious than opening a multitude of applications to seeing which ones crash, let alone the different circumstances that each program has to be under. Also, Prime95 does what most apps that crash would do anyway: overwork it.

Edit: Well, maybe not every app necessarily overworks the CPU, but Prime95 stresses it under a variety of situations.

I have nothing against Prime, but no one builds a PC to run benchmarks only. It does no good to pass Prime if things you really do have issues. BF3 and Crysis 3 both crashed for me when I was trying to run lower voltage for my system at 4.8, 1.30v. Testing is a main reason overclocking can be tedious.

But Prime didn't crash under those values?

Nope, I have yet to error out in Prime under this build. Some games that are CPU intensive, and boom it was crashing. As soon as I raised the voltage back up, neither game crashed.

How far in Prime did you go (duration)?
