Overclock i5 2520?

Hey guys, I see the i5 2520 is able to be overclocked to 3.20ghz over the original 2.50ghz.

However, I cannot find a way to do this. I am looking to do this with my netbook also and there are programs to make this happen. I am curious how I can do this with my i5 2520 just to get a little extra performance out. Here's my spec of my computer:

Thanks guys.

I am assuming you are talking about your turbo. Look at the BIOS and make sure it is enabled. Then also note that is your max turbo, meaning it will only reach that speed if you are running only one thread at the time. The turbo will be a smaller OC for each thread you add on top of it.
 
no. The computer will auto overclock when it is necessary. That is as long as the BIOS is set to allow Turbo mode.

So this can all be done within BIOS? I haven't done much playing in BIOS so i'm not overly familiar.

ok, programs are made to use a certain amount of cores. The less cores used the less heat produced. So when all the cores are maxed out it is running at the stock 2.5ghz, bu when only 3 are used it will run around 2.7, 2 cores would be close to 3ghz, and when only one core is used it will run at 3.2ghz. You cannot set it to run at 3.2 24/7 because the multiplier is locked so that it only increases when cores aren't being used fully, and the other way to overclock isn't good with that generation, for whatever reason it causes data loss or something like that and really just can't do more than like .2ghz before it causes issues.
 
Jonny, it is a mobile processor. He can use turbo, but that is it. No FSB OC at all (it does not have a FSB anyway!). But besides that it is a dual core. :(

well that sucks, and my basic understanding of the cpu was that the frequency is the fsb times the multiplier, so how can it not have one? you sure it isn't just not listed or something?
 
look it up jonny. it is not possible for first generation i series forward to have a FSB to overclock by. The Front Side Bus is the speed at which the processor is connected to the North Bridge. The i series has a platform control module on the processor that does what the north bridge used to. There is no way to have a FSB without a north bridge. The base clock does the job of the FSB now. Calculate the speed by BCLK x Multi.

well then you just disproved my whole point by saying i used the wrong word, change fsb to base clock and it works the same. Still confusing how if the first and on use the same on chip NB thingy then why does the first gen seem to overclock great on the base clock (going by black whole bench and whoever had the i3 at about 5ghz) but the rest don't? prob just changed the thing a bit, might'a done it on purpase to force overclockers to buy the more expensive k's
 
It is not necessarily the design that changed. You also have to look at it from a historic point of view. There have been plenty of processors in the past that could not overclock much if any on the FSB. The Core 2 quad 8000 series was one of them. And it could be intel meddling with it too.

But Jonny, Your point is not proven. You used the wrong term, making your point lost. YOu can not use a FSB to overclock where there is no FSB. And the Platform Control Module is ran by the base clock. In theory they do the same job, but they are not the same. Using the wrong term here leads to a complete loss of function in the computer. (seeing as there is no FSB, then it would go into messing with the back side bus (processor to southbridge), and that ends up messing with the x4 PCIe lanes (on some units), as well as the SATA lanes, and does absolutely nothing for the use of the computer. ).

anyway OP, you probably get the idea. If you set your BIOS to enable Turbo, and you are only using 1 thread, then you can get the max OC speed advertised. If you use 2 threads or more, you will not get that speed.

yes. Assuming of coarse that it is not already enabled.

I don't think it is, it tops out pretty quick but I'll look right now and let you know

Okay, new problem... I enter BIOS by pressing F10.

I then enter my BIOS Admin password and enter it again as confirmation. Then it brings me to an on-screen keyboard... I put in my password there and I got an error which told me to hit enter to restart. Tried it twice and no luck

You are only going to get he max speed on one threaded applications. Above that you will not see much if any gain on a dual core.

So there's no way to get it to run faster on all threads? I'd still like to make it work through BIOS. Not sure how to get it done though when I'm getting stuck on BIOS
 
This is why I hate the cheap people at my school that promised an i7 and settled for this piece lol

Any ideas as to why I can't get into BIOS?
 
what is it saying when you try to get into the BIOS?

And it would not help to be an i7, unless it were one of the QM verities, as you would still have a dual core, and it would still be stuck with 4 threaded apps to the stock speed.
 
It's asking for my BIOS Admin password, so I enter it twice and then it takes me to an on-screen keyboard, i'm not sure what to do from there.
 
It is telling you that your password is not right if it is bringing up the keyboard. Make sure you are entering the right password, and also make sure that you are using the BIOS password and not the windows Password.
