Hi there,
I recently built a new computer (about 2 weeks ago)
Everything went well, and I was impressed with the new system
I just opened up CPU-z today and noticed something very strange. It reported my clock speed was 4.1GHz (a massive jump from the default of 3.3GHz)
At first I was certain it was a misreading. I shutdown and checked what the BIOS reported - it reported 3.3GHz, so I thought I was in the clear. I wanted to double check, so I downloaded RealTemp and Speccy - they both reported 4.1GHz! I began to realize something was overclocking my CPU, and I didn't want that (this is a brand new CPU, I'd like to make it last!)
I got into ASUS AI suite and underclocked it using the multiplier to something more reasonable (32x) to 3.3GHz (stock speed)
Now, I'm asking why would something in the OS overclock it by default to over 4GHz? In the AI suite, if I click "OS defaults", it jumps up to 4GHz again. I'm completely perplexed, and google didn't show anyone with anything similar
My second question is how much have I damaged my CPU (or simply shortened the life of it) by running it at such frequencies for over 2 weeks? I've been doing some pretty CPU intensive stuff...I'm shocked it was so stable at such frequencies (no crashes or anything)
Lastly, I would like the turbo feature to work correctly - Asus AI suite appears to override it, so I might need to look at a different solution to 'tie' the clock frequencies down
Cheers for any info, I'm more mystified than anything else, I'd just like to know what caused this!
P.S the turbo multiplier is 37x, so it's not that!
Honestly, if it has been running for two weeks like this and been using some CPU-intensive programs and didn't crash, you don't have to worry about it. It seems like it did a overclock on it self. Just try and measure the temps a bit, and try some Prime95.
Just as a reminder, overclocking isn't a death sentence for CPU lifespan. In the case of the i5, you could run it stable on 4.5Ghz if you wanted to without decreasing the lifespan. Overclocking heavily does affect CPU-lifespan, so the lifespan issue would only arise if you start to exceed maximum operating temperatures or voltages.
4.1 is quite a low overclock for an i5. Chances are it's ASUS's AI Overclock suite.

Well I hadn't previously installed it - I had to install it to underclock it!
I'm just curious about how it overclocked itself...I don't have any OC programs on here, apart from AI suite which I just installed to underclock
Thanks for the replies

It won't go any lower on the slider..is that normal? Can someone with an i5 confirm?

Gah alright problem solved. The multiplier was set to 42x in the BIOS, and that set the OS defaults
May even keep it at 42 now :v:
Thanks for the replies
I have mine on 4.5 and it took maybe an hour of testing and testing before going to stability testing. 4.2 is basically gauranteed.
My friend has his at 4.2 on the stock cooler.

You should be fine.
