I5 2400 Overclocking

I know that the I5 2400 is not an unlocked processor and that it won't get a crazy overclock, but I have an Asus P8P67-M Pro motherboard and I would like to over clock it to 3.99ghz, because that is where Intel put the cap on the overclocking ability. If I were to do this how would I go about it, and if anyone knows if this is just Intel saying it is capped at 3.99 and it can be pushed further please tell me.

  1. You made two wrong choices for overclocking:
    1. The i5-2400 CPU. It can only be overclocked +400MHz Turbo. That means a maximum of 3.8GHz on one core only (3.7GHz with two active cores, 3.6GHz with three active, and 3.5GHz with all four active).
    2. The P8P67-M Pro mainboard. The two Micro-ATX boards that ASUS sells really suck for overclocking.

    You have to go into the UEFI and set the Turbo multipliers manually to get the maximum +400MHz Turbo overclock.

    Where did you get 3.99GHz from? I haven't seen anything that says that speed is the limit. It would be nice if that was the case, but from what I've read it's not.

    Edit: Why are you even overclocking at all? Most programs and games won't be any faster.
  2. You can not get it higher than 3.99 as the multiplier is locked to a max of 38 and base clock max is 105. 38x105=3990
  3. Ah. I forget about the BCLK overclocking, as it's definitely not recommended. It throws most of the clock speeds off for other components in the system and that can result in data corruption.
  4. so, k1114 I read the info you posted 2nd hand by the reviews section of newegg, do you have any sources?

    Is that all I have to do, change the mult. to 38 and b.clock to 105
  5. Be prepared for your board to not like the BCLK overclocking. Some can only overclock to 102-103MHz.
  6. ...so does this mean that for a gaming computer my choice of CPU/MOBO. was an epic fail?
  7. Not at all. You don't need to overclock to have an awesome gaming computer. Sandy Bridge CPUs kick butt at games at their stock speeds. Overclocking doesn't actually add much performance to gaming unless you have a low-power CPU anyway. Yours isn't low-power by any means.

    We overclock because it's fun, not because it adds performance to whatever else we do on the computer. Yes, some people overclock to increase their E-peen with bigger benchmark scores, but that doesn't translate to faster gaming with real programs.
  8. The speed that you have is good enough for games and as leaps said overclocking the blck is not recommended. Heres a link that explains how SB overclocks work http://www.tomshardware.com/reviews/sandy-bridge-core-i7-2600k-core-i5-2500k,2833-9.html and here is a link of a article I found about overclocking the i5 2400. http://www.bit-tech.net/hardware/cpus/2011/01/03/intel-sandy-bridge-review/14
  9. thanks for your honesty, as I am a first time computer builder, its hard to read about computers without someone talking about oc'ing a component. I thought it was an understood fact that people who gamed needed to oc to a certain point. I guess this makes my build that much easier then :D

    Just wondering cause I also got a rig that overclocked to 105 BCLK and the multiplier was set to a decent x36. So by from what your saying, will we find any issue immediately after setting the clock or overtime? I have been using the settings for quite a while now and had run prime95 stability test for 24 hours as well. Seems to be stable.

    I think you'd notice a bad BCLK overclock straigth away or within a few days. If it hasn't blue screened for no reason I reckon you're fine. What motherboard did you use for the 5MHz base clock increase? I'm pretty sure it doesn't do damage over time, if its gonna throw a tantrim you'll know.

  13. hello Leaps-from-Shadows....as you said we can overclocked i5 2400 with +400 MHz .would you please tell how?if you give stepwise solution then it would be great
