Hello, I tried overclocking my 965 with a Hyper 212+ and my computer froze and programs started crashing on startup. Temps were fine but id love to know why this happend. Any suggestions? Have the CPU at 4Ghz and the Volts at 1.4, am i doing something wrong?
Crashes, "blue screens", freezing and so on are all just a harmless part of the process when trying to establish a stable overclock. You aren't doing any damage to the system so long as you aren't crashing because of something like over-volting (the actual opposite of your issue I suspect). It takes everyone a few crashes at minimum to dial in the right settings- for the higher OC's like mine, I think it might have been more like a hundred crashes and a couple hours of failed startups. Just want to make sure you don't get nervous about what happened.
I would say that 1.4v is probably just far too low for your clock speed- that's actually lower than the stock voltage. May I ask if that's what you manually set it to in BIOS, or was that read from something like CPU-Z within windows?
Since I run a Asus M3A-32 motherboard I hit the Del key to go into the bios.
Head to the advance area to the jumper free section.
In there it pops up with setting things on either manual, auto, or overclock.
I set it all to manual which allows me to set voltages for my ram, north bridge, and processor separately. This also opens up the options for the multiplier for my north bridge (210), ram (set to standard clocks), and the multiplier for my cpu (standard at 17x oc'ed to 19.5).
Voltages are something you will have to look up for your own computer. My rams standard voltage is at 1.5v, your manual will tell you your north bridge voltage, and my cpu(1.43v is the base for the 965 and 1.5v is the ceiling of the chip).
I wouldn't bo beyond the 1.5v on the cpu unless your running liquid cooling.
