ASUS Overclocking Utility Question

Hi all-

I recently built my first rig. It is decidedly overkill for what I use it for (basically playing MMOs), but I wanted to have a little fun and splurge a bit. :)

Some specs are an intel i7 4770k, noctua NH-U12 S cpu cooler, Asus Z87 Pro mobo, 16 GB (4 sticks) Crucial Ballistix Sport RAM running at 1600, 750W power supply

I used the ASUS AI suite to let it overclock itself, and I got what appears to be an insanely good overclock, so I am worried that the program has set me up for failure.

I chose the "Extreme" option as it was at default. I let the system run and when all was said and done it is showing me an overclock of 4.8 (fluctuates between 99.9-100.5 x 48), confirmed by CPU-Z which shows it actually fluctuating between 4.8 and 4.9 and has the multiplier reading as x49.

Temps seem to hover in the high 40s to mid 50s when I'm gaming high 30s to low 40s when i'm not, but the max showing in core temp is in the low 70s(not quite sure how to make sense of this readout quite yet, I'm assuming that is the max it has hit in the session?) Even then my GPU doesn't really get over 50. I've confirmed these readings with SpeedFan (though it is always lower than Core Temp so I don't really trust it) and Core Temp. Heat doesn't seem to be an issue.

The voltage according to CPU-Z fluctuates between 1.25 and 1.275.

I haven't put in any marathon sessions yet, but I have used it for a solid 3-4 hours with no problems, so I'm assuming it is stable? (The only instability came when I accidentally set my DRAM frequency to 2333 or something like that when I meant to set it to 1600...I just went in and set it back and everything's been fine since).

TLDR: The 4.8 seems too good to be true, so I figure it is. Most of the reading I've done seems to show people sitting around 4.3 at 1.2V. I realize I'm coming close to 1.3V, but the temps seem to be just fine. Should I just hush up and thank my lucky stars that I got one of the "good" chips, or do I need to be worried about something? Really I'm just overclocking because it can, not because I need to, and the last thing I want to do is push the system too hard and wreck it.

Thanks in advance for any and all help you might offer this overclocking rookie. :)

i had a very similar issue on the Asus Maximus V Extreme although it's a Z77 chipset board. i had to uninstall Asus Suite to get the correct temperatures so, you may be correct in saying "it's too good to be true." a friend of mine also had similar issues with his 4770k... core temp was reporting temperatures that were well below what his actual core temperatures are.

to get accurate core temperatures, we had to completely exit out of the Asus Suite software (or better yet uninstall it) and then run core temp or whichever temperature monitoring program you use. however, it's also be possible that your chip is awesome. :)

Thanks for the reply! I will check the temps again as you have described when I get home. Just wondering, when you got incorrect temps were your fans running like they should have been, or were they acting like the system was cooler than it really was, too? My case fans rarely kick on until I've been doing something for a while, though I can hear the cpu fan whirring away.

hmm for me, the CPU fans were spinning like the CPU was indeed cooler than it actually was. i don't use case fans so i can't mention on that one^^

I didn't have much time tonight, but I shut down the ai suite and ran core temp for a bit. Temps seemed to be the same. I will do the uninstall/test method when I have a little more time. Thanks again for your help!

anytime, if temps still look good after uninstalling the suite, that's a fine chip^^

Just an update. I closed out AI suite and temps still read fine. I did have the system lock up on me after about 3 hours of gaming despite fine temps, though. I suppose it could have been anything since this is the only time in about a week it had happened, but better safe than sorry. 

So until this weekend I backed the overclock down to 4.3. When I have some more time I am just going to redo the overclock as it was, uninstall AI suite, and run aida64 for a few hours to see what happens. I will post the outcome provided my computer doesn't explode :)

I updated some drivers on my system and redid the overclock using the asus ai III utility. I exited out of that and let aida64 with all settings checked run for three hours and 45 minutes. When I came back, nothing had crashed and the system was still running. However, along the bottom I noticed that there were some times that the cpu had been throttled due to temperatures. They were always very small blips.

So, my question since I'm new to this is: is that normal? Does a stable system still have some times when there are blips that cause throttling, or is my system unstable if there is even the slightest throttling? My guess is no and that this is a sign of an unstable system, but I also wonder if it is something I should worry about since these minor blips happened during circumstances that I will most likely never recreate during use?

if your CPU is throttling because of the temps while running AIDA but, never when playing games/using the PC for general things (which should be the case), you should be ok. if it's just your temps that are causing the CPU to throttle, i don't think it's a sign of instability but, just the fact it's too hot.

however, maintaining temps of 70C+ (or a voltage higher than 1.3v) for a elongated period of time isn't recommended as it may lead to possible degradation of the CPU. i try to keep my chip under 70C @ all times and the only times i'll see it hit 70C is in CPU intensive games such as Battlefield 4 and Crysis 3; 70C is reached only for a brief moment when the game causes a CPU usage spike, other than this, the temps average around 50C-55C.

Thanks for the info! Despite the apparent stability, the system crashed after about an hour and a half of playing final fanttady div, which isn't all that taxing. I had my temp monitor up and temps never really got out of the 60s, but apparently the system didn't like something. The mini dump file says it was genuine Intel that caused the crash so I'm assuming it is the processor and not just a driver. So, I'm back to stock settings again. Played for about 2.5 hours later and no crash, so I'm back to the drawing board. :)
