Games are crashing after overclocking

[mORTcube]

Hey everyone, I got pretty damn old cpu ( AMD Athlon 64 x2 5200+) and i noticed that in some new openworld games or big multiplayer its really big problem for this cpu to handle that and its bottlenecking my GPU ( GT 630 1GB DDR3/ OC 1034 MHz). So i find help on the internet. They told me to oveclock it because its still running at default clock (2,7 GHz) So i tried. In the bios i set the core clock to 3.2 GHz and tried it. It was pretty unstable, like every game i tried to run, it crashed. So tried it again. I set the 3.2 GHz core clock but i change the voltage to 1.420. I tried it and windows and everything was running just fine... then i tried some games and again it crashed. I really dont know whats the problem ? Is it too high for this cpu ? My friend told me that it could overheat, but temperatures are fine, its about 35 Celsia in Windows and around 60 in games. This is my motherboard: http://www.asrock.com/mb/AMD/960GC-GS%20FX/ and this is my cooler: http://www.zalman.com/global/product/Product_Read.php?Idx=450 . Please help. I really need to overclocked it cause its really slowing me down in games.

Try lowering it to 3.0 or 3.1ghz. 1.42v should be enough for 3.2.... And lastly, your gt 630 isn't that much of a high end GPU (no offense). So that GPU isn't much bottlenecked by your CPU.

The CPU doesn't have to overheat to crash. If the voltage is too high, or it's just unstable at that frequency, or the MOTHERBOARD could have difficulty maintaining the voltage within tolerance.

If the game runs WITHOUT overclocking the CPU, but then crashes after overclocking then you either did something wrong or your CPU just can't handle that overclock.

Your CPU is so old that you aren't going to solve your problems anyway likely by just overclocking it.

Alright Im back, i set it to 3.01 GHz and 1.42v.. it wasnt stable. Then i tried 3.01 GHz and 1.5v and its finally stable, but isnt this dangerous for my pc ? And yes i know its low end GPU card but in some games its running only about 40-50% of Usage and its causing low framerates which is annoying.

1.5 is still fine but it's going to run hot bro. Always keep an eye on your temps!

It sounds like your CPU is still bottlenecking the graphics card. Not much you can do aside from buying a new PC.
