i have c2d e7400 2.80ghz, 4gb ram, gtx 650.
my system is prebuild so i cannot overclock through bios.
then i used setfsb and overclocked it to 3.25 ghz from 2.80ghz at stock cooling and cpuz show 3.25ghz speed but in games like gta iv, crysis 3, mafia 2 or dolphin emulator(which soley depends on cpu clock), there is not even 1 frame increment.

it's because that cpu is very limited, you're looking at a old lga 775 (not saying its bad but yea its old). Increasing the clock speed increased its speed slightly but it still has to render everything which it's bottlenecking to do. I dont get it, forget about everything cpumark didnt increased 1 point score.
i saw many people which overclocked c2d e7400 and saw difference.

Ok ill start off with, you can't overclock because its a prebuilt locked bios computer. So you use a overclocking software that supposedly increases the frequency of your cpu. Now since your running a extra program trying to get more performance out of it, what's actually happening is it has to process more and possibly that boost in frequency is just covering that so you gain nothing. Next up it could be your harddrive depending on what it is. If it's an IDE harddrive you are probably hitting it's limit on data transfer so any overclocking you do is still restricted by the amount of data that can go through a ide cable. Next would be the cpu itself. It may think its overclocked but it still has to do everything like it did before. Lets say i pulled out my old dell computer with a 2.8ghz p4 478 socket and overclocked it to 3.5ghz, Should i see a increase in speed? depends on the application. Multithreaded applications require more processing power so it still lacks it even though it is clocked faster. Think of it this way. You have a 4 lane highway from your harddrive and your cpu has 3 lanes. You increase the speed limit, but it causes more congestion at the point where the 4 lane highway becomes 3.
