Quick background - I'm new to the hobby, longtime lurker/researcher. Just finished my first PC and my first overclock. I'm just looking for feedback from some people with more experience than I do.

I've done some research and off the advice of a couple people, this is how I overclocked. I'm not interested in getting flamed for this, however if there are any major issues by doing this, please let me know. I allowed AI Suite 3 Optimization software to get everything to 4.6Ghz. After that, I started scaling back the voltage manually in the TPU tab and stability testing it for 20min with AIDA64. I've arrived at 4.6Ghz @ 1.185v and stressed 3+ hours on AIDA 64.

My questions are these...
- How good are those numbers/temps?
- Will running at that voltage in manual and not adaptive setting have any long term effects? I don't care about the higher energy bill, I just want to make sure the chip will last 4-5 years.
- Should I overclock it more if those numbers are really good? Keep in mind, I not interested in really pushing the system, but I do want better performance if its not going to sacrifice the CPU...
- These settings are saved as a profile under AI suite, every time I reboot, it goes back to adaptive and higher voltages and I need to reload the profile. How do I change that? Do I need to just change the voltage in the UEFI to manual and set to 1.185 or is there anything else to do?

Thanks much for the help guys,
Adam

I don't think its that Aida64 isn't doing a "good" job, it just that Prime95 pushes MUCH HARDER. In fact, arguably it pushes the proc too hard. Unrealistically too hard. Although your IB i5 3570k may do just fine running Prime95 for hours, the core architecture of Haswell is different and it just doesn't tolerate Prime well, and will heat up to 90-100C almost instantly.

It just the way it was fabricated. Thank Intel for that one.

I actually have had excellent results running Aida64 stress test with my i7 4790k, and am confident with the OC's I am trying. I don't need to fry the thing just to be sure its stable.

Good job OP, I would be happy with where you're at. DC is screaming fast at 4.6GHz. The days of 5.0GHz OCs are rare...

first off I seem to find that aida64 doesnt do a good job of stressing, Ive had aida results that make an OC look stable but then Prime95 runs 3 seconds and BSOD.

Running in manual mode is what a lot of people use for their OCs its fine to use.

I would certainly go higher, temps and volts are VERY low

Yeah, I'm definitely going to see what it can do with those numbers. I thought they looked pretty darn good, but I haven't had the hands-on experience yet. I will see what it would take to run at 4.8, since I also just noticed that my fans are only running at 50% during the stress test.

Your answer about what I have cooling...
Define r4 case with front harddrive mount removed
4x Corsair AF 140 fans - 2 front intakes, 1 rear top exhaust, 1 top rear exhaust
Noctua NH-U12S with 2x Industrial PPC's (noctua's new fan, they look great btw) set in push-pull.

Hi!
I am also new in overclocking. Would it be possible for you to share your overclocking parameters of CPU (voltages etc)? What kind of cpu cooler are you using?
