I just recently built a budget gaming computer for a friend. I was looking through the bios, and noticed that the cpu multiplier option went all the way up to 36. Now, this is a locked Ivy Bridge processor that comes stock at 3.0ghz. I thought that the non-k series weren't supposed to be overclockable? Additionally, would this change occur across all cores should this work? I'm not certain how well the Ivy Bridge series overclock in general, so I'm also worried about having to change the voltage to achieve this clock speed. It's a MSI motherboard with a z77 northbridge.
All the non k i5 and i7 can go up 400mhz and is essentially just changing the turbo. 3.6ghz when using 1 or 2 cores, 3.4ghz when using 3 or all 4 cores. (Note: on this cpu turbo only has 2 levels, while other quad cores may have 3 or 4.) It will still be 3.0 when not using turbo. You can leave the voltage alone. It will usually go up to 4.0ghz or so before you need to raise the voltage but you can't go that high.
I have manage to overclock my 3330 to 3.6 GHz... up from 3.0Ghz. Would add a CPU-Z image onto this thread (as proof) if I could find the "add attachment" option. All I did was update the CPU ratio on my Asus P8 Z77-M. Im no pro at overclocking but all i had to do was increase the CPU multiplier.
I did a few 3dmark vantage tests as well (just to be sure)... each 200Mhz increment kept giving me hight 3dMarks. So i guess it must be working...?
Question: How would I know if the tests I was running were running on 2 or 4 cores...?
Question: Anyone know of another utility I can use to reconfirm my CPU-Z read outs...?
You can set the number of workers in prime95. You can see cpu usage per core in task manager. And you can change which core cpuz is saying the speed of (right click anywhere in the clock section, default is core #0). Just trust cpuz.
Hi, very new to this forum but thought I'd come straight here as I've just finished building a new pc with an i5-3330 and a 2gb 7850.
Just interested to know what, if any, results others have had with overclocking their i5? I'm currently only using the Asus AI Suite II (the TurboV Evo tool within it) and have managed to get my speed up to 3.638 (107.0 x 34). Any hints/tips how I could get it any higher? Not really comfortable messing with the voltages to be honest - last thing I need is a fried cpu at the moment.
