AMD Athlon II X2 240 Overclocking Problem

post #1 of 8
Thread Starter 
Hi i have problems overclocking my amd 240 cpu. I tryed OCing with AMD OverDrive software on Auto Clock mode but the result was only 208 MHz (200 default). I try few times manually to go to 220-230 but i get a blue screen and the pc restarts. I try OC it from the bios (and save the settings) but after restart the bios settings restarts to default. Any advice? Here's my comp specs and pic from my current cpu settings.

AMD Athlon II X2 240 CPU
Biostar A780L3 Motherboard
2GB DDR3 1333 RAM
AFOX 250 GTS 1GB GPU (10%+ Overclocked)
Chieftec ANP-405A12 405w PSU

First change your memory multiplier to a lower value, so your memory is actually running slower than 667mhz (1333mhz). You may have to check your BIOS for this option.

Retry your overclock again.

That should work. I also forgot to mention, you may want to use a lower HT multiplier, use 9 or 8.

I notice your CPU voltage is at 1.425v already. You can definitely get away with just using 1.35v for now.

I make the voltage at 1.35v and try to make the HT multiplier at 9, but the pc freezes, restart it, and try with auto clock, again pc freezes. Whats wrong why is this happening?

Boot into safe mode and disable Overdrive from running.

Also reset your CMOS. Likely there is some setting that is causing your freezing at stock settings.

Additionally, check your OS for corruption and HD for bad sectors to rule out those problems.

If your system is crashing at stock, then do not overclock anymore. As I stated, read up on your manual, it should tell you how to reset the CMOS, this is where the BIOS is stored.

Next, run a checking utility on your operating system to see if it is still good. If you're using windows, this can be done from the properties of the drive.

Uninstall Overdrive to make sure that Overdrive is not causing the problem.
