Been a lurker on these forums for ages now, just decided to join lol :) 

Anyways I recently upgraded from a very outdated Pentium D pc, and built my own i5 Sandybridge rig...
Intel Core i5 2300 @ 2.8Ghz
Biostar TP67B+ Mobo

I've been reading everywhere that it's possible to overclock the 2300 to at least 3.4Ghz, is that possible? I searched all over but couldn't find a decent guide to overclocking this processor or even the 2400 variant... are there any detailed guides out there for overclocking an 2300 that are good for a newbie overclocker like me?

I never bought a cpu with an unlocked multiplier cause this one was on offer, managed to save about £35 on it :) 
I'm not after any massive speeds or anything above 3.8Ghz, I would just like a nice increase to probably round about 3.0ghz - 3.5ghz.

By the way, I'm still using the intel stock cooler (35'C stable with a CM elite case)

Thanks in advance :D

Go into your bios and change your multiplier to the highest it will, save and exit. You shouldn't have to change any other settings. Then stability test it with prime95 while watching the temps with hwmonitor. It OC the same way as a 2500k but has a locked multiplier, probably locked to a highest of 35.

Thanks, just did that before.. are these temps too high?

Multiplier: From 28x to 32x
Base clock: 100mhz to 105mhz
Clock speed after changes: 3380mhz (avg)

And idle temps are:
Avg: 45'C
Max: 51'C

Full load torture test using Prime95 (In-place large FFT'S) Temps:
Min: 59'C
Avg: 65'C
Max: 74'C

Thanks in advance :)

How long did you run prime95? Those temps are fine, a little high idling. What's room temp?
