Hey, new to oc in general, but I was wondering if anyone could answer a quick question. Is it possible to oc an i3-2120 on this board (asrock p67 Extreme4 Gen3)? I have been trying all day by following the guides and have yet to produce anything stable frown.gif Just want to play with it until ivy comes out and I can grab an i7

My build is here if it matters (first one biggrin.gif): http://www.overclock.net/lists/display/view/id/3990022

Based upon this thread where a user tried to overclock their i3-2100, I would say no you can't. http://www.overclock.net/t/1244211/overclockig-i3-2100.

The i3-2120 isn't meant to be overclocked. You can increase the BLCK, but that is extremely dangerous to do and can damage the processor and motherboard.

Dawww. Fair enough I guess. Would of been nice to see the look on everyone's faces having an i3 at 4.8 GHz wink.gif

Yep, the only you could do is try and set the BCLK at 104 or something (it has been proven that up to 107 can be safe; it almost will never POST if you set it to high.)

Next time be sure you get a processer with the name that has a "K" at the end. Those are the ones with unlocked multipliers and able to OC!

True that! To be honest the only reason I didn't get a K was because I thought ivy was "coming out soon". But then the push backs happened x 4 and suddenly what I thought would be released in December is now..."April" T_T gunner.gif

I was reading the question about OCing the i3 and numerous folks pointing out that he could only up the BCLK a bit if he wanted. This begs the question, what ever happened to OCing via FSB? I know through the Lynfield systems that was still the way to do it. Did Intel shut the door on that with SB, and if so, then they are limiting OC-able chips to the K-series only, which fetch a premium. Terrific chip my i5 k-2500 is, but I guessed they shut the door on overclocking by other means.

This reminds me of my kt-600 Via chipset Albatron mobo, when I had a Athlon Barton 2600 mobile that was unlocked. The Via chipset did not lend itself to OCing by bumping up the FSB as the AGP and PCI buses were not locked (and thus bumping the FSB caused all sorts of havoc potentially on storage and other peripherals). Anyway, with that 2600 mobile, I was able to get that chip to run at 2.6GHz, which is 2004 was pretty damned fast, and that was pretty stable and cool. But mobile chips were the exception, as most OCing occurred via FSB.

Anyway, do any of these SBs (and Ivy Bridge down the road) OC via FSB, or whatever it's called nowadays?

It's more of a hardware limitation. The memory controller and iGPU, among other important hardware things, are now integrated and/or controlled/influenced directly by the CPU itself. So Sandy Bridge (and I'm assuming other new architectures) doesn't have a FSB like you might think. Instead of a FSB it has a BCLK or Base Clock setting. When you increase the BCLK you also increase the speed of the dependent hardware. While things like the iGPU might just "not work" if overclocked to much, items like the memory controller do NOT like to be sped up. A certain point ~107+ BLCK it gets so out of range that things just start to fail, bits begin to error, and can even cause a Windows 7 to corrupt!

In short, its not a limitation Intel put on it, but merely a consequence (or adaptation as I think of it) of a new architecture. thumb.gif

It's amazing how you can take away a complete overclocking feature (FSB) and still get MUCH higher speeds by just using the multiplier!

Well, I think I may have won the processor lottery! I overclocked my new 2500k to 4.8 Ghz, with a fixed offset of +0.030 and LLC Level 3. I ran prime 95 blend for I believe 12 hours (stupid computer installed windows updates and restarted after I'd say about 11 hours of Prime 95). How I know it didn't crash was Windows didn't give any notification that it recovered from a crash, but did say it installed updates, so that is good.

Max Temperatures went up to 75C, (very rare, usually it stayed around 70-72) but here is where it gets awesome: I managed to get my 4.8 Ghz stable on 1.344 volts with a vdrop of about 0.008 (1.338)! So 24/7 on 4.8 Ghz here I come!

Screw that. If you don't get 5Ghz with that gem, I'll punch you in the face! thumb.gif

My 2600k was the same way... Up to 4.7ghz required no mods for complete stability & .030 offset @ 4.8ghz w HT enabled. Going beyond that, however, becomes much more difficult. Takes upwards of .140 to hold 5ghz with HT off. Giver & good luck from here out.thumb.gif
