Voltage problem 3770k

post #1 of 10
Thread Starter 
Im trying to OC my 3770k to 4.5ghz. I have a manual voltage at 1.25V to start out. When I go into windows and run prime95, my voltage drops to 1.21v - 1.23v. I also get a rounding error in prime within 8mins. But no BSOD.

You need more vcore. You can fail prime without a BSOD.

But why is my voltage dropping under full load? When idle, its at 1.25.

Not sure why it happens but I always have some voltage fluctuation as well, it is normal.

I just put LLC on ultra high, was on high. Now my voltage doesn't drop. But im still getting the same rounding error on prime 95. Any idea why?

When overclocking when you increase your clock speed, you need to increase your voltage to maintain stability. It seems you are slightly off due to not bsoding, so try a slight voltage bump up.

What everyone else has said. Your gonna need more volts or turn down your clock speed. Any errors is a sign of instability.

It's normal for voltage to drop slightly under load, its called vdrop/vdroop. Simply use a higher CPU LLC setting or increase vcore a bit to compensate. Keep increasing vcore until you don't get errors. If you can't pass at 4.5GHz by the time you are hitting 1.35v you are either heat limited or your CPU is just a lemon. If you are trying to OC on the stock intel cooler... well I don't think I need to say just how stupid of a idea that is.
