What's with my new i3 speeds?

post #1 of 8
Thread Starter 
Morning,

I will start off with that I'm 99% sure the answer to my question is just me not knowing how some of this works, so no I don't think it's broke I just trying to understand what it's doing. I just built this new PC so I'm not as familiar with the newer stuff. Here's new system, nothing fancy, on a budget:

i3-2100
Asus P8H61 mobo
8GB Corsair 1600 ram
nVidia 9800 GTX+
Maxtor 250GB hd

That's about it, nothing else really important

Ok so I know the stock speed on this i3 is 3.1Ghz. So I was installing drivers from the disc and updating BIOS and such and I noticed when the bios first starts in normal mode it says "Speed: 3220", and I was like "hmmm that's odd, should be 3.1ghz".

Then on the autorun of the DVD that came with the mobo there is a "motherboard stats" which loads a web browser page of stats and it said 3200 for speed. Again kinda weird to me

So I thought "ok I'll get CPU-Z and get an accurate reading". Well it said 1500MHz! AHH! And I ran the Asus Suite 2 and it showed similar. So I'm like "ok so what is the actually MAX it'll do stock without trying to manually OC it? 3.1 or 3.2". More so out of curiosity, as yeah I realize these don't really OC, not something I planned on doing.

So I realize something is throttling the cpu down while just in windows doing nothing is why it read at 1500mhz. As when I opened a program CPU-Z would shot up to 3092mhz briefly then go back down. So I tried turning of EPU in the bios as I "thought" that was controlling the throttling but that did not seem to affect it and it was late so I went to bed

So I guess my questions are, what's actually throttling the thing, where is it? And I'm slightly paranoid and wonder "Am I actually getting the full power/speed when I open a game or something?" or is it going to throttle back mid-game and affect performance? Though I realize that's probably not the cause but curious and slightly paranoid

Chances are, Windows is "throttling" the CPU based on activity. If you're not using the CPU, it will downclock to conserve power. Otherwise if you are actively using the CPU, the speed will ramp up to it's normal 3100MHz (3.1GHz).

You can go to power options in windows control panel and set it for maximum performance or minimal power saving mode.

Really, it's windows? Hmmmm

Is it only with "newer" (I use the term loosely, you'll see why) cpus it does that on then? My old PC, which is almost 6 yrs old, never did that, it was always the constant top speed stock and when I OC'd it. And I was running it on the same Win7 64bit. It was basically an Athlon64 X2, socket 939 (actually an Opteron).

Hmmmm but I didn't have that one on normal "auto" mode for much of it's life, so I guess it probably wouldn't have done that since it was manually set cause of OC'ing.

I'll have to look at those options when I get home. So do I lose any performance by letting it do that? I do walk away from my PC for hours a time, so I am open to the idea of reducing my electric bill (if i'd even notice it, ha ha)

it is speedstep, its not windows, its a feature of the core Ix series where it can change the multiplier to meet demand so if your doing nothing or something with no intensity such as listening to music while doing a word doc it will lower the processor speed to conserve power, now say all of a sudden you jump into a rendering a video it will clock it to it's max rated freq. as long as it is in thermal range.
You can disable it if you want in the bios of your board it's usually located with the c states in most.

You really have nothing to worry about, its perfectly normal for your CPU to throttle down when it is not under load, This could and probably will extend the life of your CPU even more considering its never running at its full 3.1ghz when you aren't using it.

Its like a car engine, when your not demanding anything from it, you idle around 800-900 rpms, but once you need it to get you going, you step on the gas and the engine revs up moving you along as you need :-)

You can however go into your Bios and disable Intel Speed Step, C1E support and such to disable the throttling. But why leave your engine running when you don't need it?

You really don't lose any performance at all, On my computer I have mine overclock to 4.4ghz for daily usage, but it throttles down to 1.6ghz when I am not doing anything demanding, like browsing the internet or just looking at photos, but once I play a game or do something CPU intensive, it hops up to 4.4ghz and gets me going.

Alright, thx

I knew why it was doing it, just it's a new feature "to me" so I wasn't sure if it worked as well as it stated. Like my thought was maybe it was actually slower switching speeds somehow, than just leaving it running.

I'll probably turn it off to play with it but ultimately leave it on now that I know a bit more.

As far as extending the life of the cpu, ha ha. My last cpu was OC'd 800hz over stock (a lot for back then) and it's lasted 6 years! It still works, but I hate the thing, can't stand using it. So this one could last less and I'd be ok with it

My budget is tight though, so I'll probably leave it on for the tiny difference it'll make in my eletric bill over the old one.


One unrelated question about my new system. I think the answer is NO, but does my board have that feature where on the desktop it uses the iGPU, and then in a game it uses the video card? I saw in the nVidia options it had the ability to set either as a separate PhysX processor

Unfortunately it doesn't the only chipset that supports that at the moment is z68.
