As you probbably know, the Intel Clarkdale processor comes with graphics and memory controller integrated into it. A voltage bump in this delicate CPU would mean damaging the internals of the processor.

It is really unfortunate that this happened to me. My Core i5-661 is dead. No matter how many boards and ram combinations I use, the Dual memory channel set up just couldn’t POST. The processor still works but it is now running in single channel memory mode.

So, be exceptionally careful with your Clarkdale processors whenever you test new bioses or bumped up the voltage levels.
