Hi everyone,

Just finished building my new pc this week. Finally got around to overclocking it this evening.

Quick Breakdown of specs.

I5-4690K
Asus Sabertooth Z97 mark 1
16GB DDR 1866Mhz
Cooler Master Seidon 240L cooler

I just used the built in over clock function from Asus.

Currently running stable at 4.6GHz Core voltage of 1.277

Idle temp is around 32C, running the Intel Extreme Tuning Utility temps max around 72C they bouce around 65 to 72

Is this ok? I've spent the better part of the last hour reading posts some people seem to consider this high others not.

Just looking for some opinions. Not sure if I should try for more manually or just be happy with this right out of the box.

Thanks!

Jeremy

If you need the overclock I'd play around with it and see what you can max it out at without burning up your CPU or going over 1.3V but otherwise you should be good if you're just going for gaming and mid-range tasks. If you plan on rendering videos all the time, using CAD software or stuff like that you may want to see how high you can overclock without problems. Prime95 is a good stress test but some people have issues with it, HeavyLoad is the one I always use.

The problem is that recent versions of Prime95 (v28.5) run FFT's optimized for executing AVX/FMA instructions on the FPU of your processor. Like Prime95, AIDA64's FPU test also runs AVX/FMA instructions. Both tests commonly result in Core temperatures close to Throttle at 100C, which is partially due to the higher Vcore required to execute AVX/FMA instructions with stability.

Keep in mind that Prime95's author is on a quest to find the next prime number, and AVX/FMA code greatly accelerates high-level number crunching, as well as compiling and running A/V encoding for apps that many of us, especially overclockers and gamers, will never use. However, that doesn't keep the playing field level for overclockers that use Prime95 to provide a consistent thermal benchmark.

All versions later than 26.6 include AVX/FMA code, which produces extreme temperatures on 22 nanometer 3rd Generation Ivy Bridge and 4th Generation Haswell / Devil's Canyon processors. Although 32 nanometer 2nd gen Sandy Bridge processors have AVX instruction sets, they don't suffer from extreme temperatures because of a soldered Integrated Heat Spreader and a 35% larger die, both of which dissipate heat much more efficiently. *

If we go back to 2006 when Intel won the performance crown away from AMD with their Core 2 "Conroe" processors, then fast forward to today's Devil's Canyon processors, Prime95 Version 26.6 provides the consistency and uniformity needed for testing all Core i and Core 2 processor variants. The bottom line is that if you don't run any apps which use AVX/FMA code, then there's no point in configuring BIOS for the higher Vcore and lower clock speeds required to accommodate stable FPU testing at Core temperatures in the 90's.

Try running Small FFT's using Prime95 v26.6 - http://windows-downloads-center.blogspot.com/2011/04/prime95-266.html - You can configure your BIOS to run a higher stable overclock on lower Vcore with Core temperatures 10 to 20C lower.

CT :sol:

* Intel Overclockers will remember the Core i 2nd Generation 32 nanometer Sandy Bridge as the last processor which was thermally "well behaved".
