Not all chips can be overclocked the same .....even if they are the exact same cpu. Some OC better than others. My chip runs at 5.2GHz ....well I should say when its on. I turn it off every night. Never leave it on 24/7 Also the make of the motherboard is VERY important. Some are much better than others. The one I use is made for overclocking. That's its main feature. Everything is Air cooled in my rig, I've got a huge tower with 6 fans blowing at all different locations. Also got a portable AC close to this rig for the summer time heat. LoL Both your rigs are laptops ....no offense but they are hard to keep cool when overclocking. My computer case empty weighs around 45lbs .
Catch you tomorrow Rod.
