→Extreme fluctuation emulation speed
If PCSX2 still crashes after doing all of the above, check that you aren't using any speed-hacks and that your system is stable and not overheating especially if you are overclocking.
===Extreme fluctuation in emulation speed===The large fluctuation in emulation generally are is often caused by the games themselves and cannot be avoided , but there is a handful of cases where this is caused by specific configuration issues
* Using large internal resolution multiplier on a lower low-end GPUGPUs, even if the game runs mostly fine some effect can cause the emulator to suddenly have to do a lot of very heavy operation operations on the VRAM, lower GPU low-end GPUs tend to have much lower VRAM bandwidth and will get absolutely crushed by what PCSX2 tries to dothat, especially true when using Large framebuffer and even more so when using the OGL renderer, obviously . Obviously the only real fix is turning the resolution down and disabling Large Framebuffer if possible* Playing the game games directly from the original DVD using a disc drive, in which case you should [[Ripping Games|rip the game]] and play using the .iso instead
* Having the Blending accuracy set too high in the OGL renderer (Full and Ultra mostly)
* Using EE overclock in some games
