Benchmark Results: Crysis
Crysis is a handy real-world benchmark because it shows performance differences for nearly every hardware change. These are most noticeable at lower settings, such as 1280x720 with anti-aliasing disabled.
ASRock’s higher-frequency “Turbo 4.6” mode puts it ahead of Asus in “Auto” mode, while Gigabyte’s slightly higher DRAM data rate edges out Asus with manual overclocking. The P8Z68 Deluxe looks good in the balance.
Performance differences between motherboards are minimized at increased GPU resolutions. Even the mighty GeForce GTX 580 bottlenecks Crysis!
CPU clock takes precedence at our higher-quality Crysis settings, yet even that variable goes away when resolutions are pushed to 1920x1080 or higher.
1) It either is super conservative and therefore useless for any enthusiast.
2) It is insanely over-aggressive because it doesn't bother testing stability for more than a few minutes (if at all). So you end up with it thinking a 50% overclock is "stable" when it totally isn't.
Turned out that with all other settings as chosen by the utility the peak core could be set to its lowest value in the BIOS and still be perfectly stable. So is it just ramping up the voltage to be on the safe side?
I have downclocked my system to base settings on both the CPU and GPU because the wear on the system with OC'ing. None of the games I play, nor any of the other apps need a OC to perform well, so why place additional stress on the components when it is merely for bragging rights?
When I played with manual OC'ing I found, like this article, that there was only a marginal gain from auto settings. Plus ther is the additional risk of screwing the pooch entirely and bricking the CPU or mobo by overvolting.
Unless you are a real pro and are not risk adverse, I'd recommend that you stick with auto OC'ing, and for this, ASRock has proven to be the best.
I feel that Toms should have done some stability testing on their manual and automatic OCed Processors. They might have and just not posted their results. I am in the camp where I feel that if you can't take the hour or two to figure it all out you probably shouldn't be Overclocking. If we had a larger sample of Proccessors we have no idea how many would turn out badly.
It looks like a good tool to start off your own OC because it's probably gonna be in the ballpark, but on it's own it leaves much to be desired.
