Safe Overclock?

post #1 of 4
Thread Starter 
This is my first time overclocking...

3570k
ASRock Z77 Extreme4
Coolermaster evo 212


I have my CPU at 4.3ghz and the voltage at offset +0.005.
Speccy says my CPU is at 63C on full load of prime95.
On full load, 4.3ghz and my core voltage is at 1.152V on full load is that safe?

Here is a picture of my CPUZ at full load.

Overall is this overclock safe?

It's very safe.  However, I need to ask one question in order to be absolutely sure:  which power supply do you have?  I mean, what's the brand and model?  Some PSUs should be avoided, especially for overclocking because they are just that bad.

It's a computer!

1.152v is pretty safe. So is 63 C.

that is probably below what your cpu would run if you left everything stock in bios and then stressed tested it . to be stable at 1.152v at 4.3ghz is a blessing and I would consider that a good chip. and 63c max at the core is also amazing I had 1 3570k and 3 3770k's and none of them could get 4.3 with less than 1.25v and temps into the mid 70's so you should be happy.

so yes your temps and voltage looks good but you may have not tested your overclock for 24/7 usage yet. I do 50 run of IBT on max than 24 hour prime. but 20 and 12 is plenty
