I hit a wall at 3.8ghz, Core i5

I have had my i5 for awhile and have had it set at 3.8ghz at 1.26v since the day I put my rig together and it has been incredibly stable. But a few times I have decided to not be satisfied with a 40% overclock and push it further, however no amount of voltage on the vcore seems to get me past 3.9ghz with anything but benchmark stability. The second all 4 cores kick on it shuts down. I set the RAM deviders low it is running at only 1200mhz when trying this.

 

Alarming when i set voltage above say 1.3v it makes a very audible clicking noise like old computers seem make, you know the electronicy noise? I don't know how to explain it. i think it may be a motherboard issue because the UD3 isn't exactly a high end board.

 

I know some processors don't overclock well but this one runs at 3.8ghz at a tenth of volt above stock. Please help me.

 

Is there anyway to get this stable? Oh and specs are in sig.

 

Edit: I switch off load line calibration and the clicking has went away at high voltages and I am running it at 4ghz right now. Any explanation for this?

Have you tried tightening or loosening your RAM timings? On my Phenom II X2 550 the only way I could get past 3.8GHz was by nudging the PCI-Express clock ever so slightly. Nudging it from 100MHz to 110MHz seemed to fix it although I'm not sure how safe it is to do that.

I took the ram out of the equation by lowering than stock. I disabled the vdroop compensation and I have been having better luck, I am having a little trouble getting it stable I think I need better cooling to go any higher.
