Snagging 4.7ghz on a 3570k 2nd core failure?

post #1 of 4
Thread Starter 
I am overclocking my 3570k and I am trying to settle with 4.7ghz and after a few hours of prime95 blend core 2 fails but the other 3 cores will run 8 hours + no problems.
I am using a water cooled loop so temps are not a issue they are amazing maxing at around 74c.
I am using 75% load line and I tried both 1.34vcore and 1.35vcore to no avail everything else is pretty much set to auto is there anything else I should mess with or should I jump to 100% llc.
My motherboard is a ASUS P8Z77-V.
I really don't want to add that much more vcore but I can tolerate a little.
Just really need to fine tune this in it seems rolleyes.gif.

You can refer to this thread here in OCN for a full guide as well as tips and tricks.

Personally I needed 1.376v to get my 3570K @ 4.7GHz perfectly stable. Passing the Prime test is only the first part, you'll have to stop the WHEA errors in event viewer after, then deal with the crashing games. IMHO you need not worry as much with temps on Ivy because they are meant to run hotter than your standard Sandy or 1st gen i-series processor. 10 degrees hotter to be exact, meaning if you find 70 degrees your limit you can adjust that to 80 and so on. As for me, my max temps are in the low 80's but usually hover in the mid 70's under load which I find is perfectly fine (only time will tell though. lol)

Hope this helps. Cheers. smile.gif

I think the voltage is starting to leave my comfort zone rolleyes.gif.
I am doubtful that it makes any difference running these higher clocks in games.

You definitely won't feel any difference with 100MHz so you can decrease your PC and leave it at a certain voltage that would keep you comfortable.
