Both the Mobo and CPU muct be up to the task...My Mobo is weaker than other UD4P's that ive set up for Friends...My M3A79T clocks all my X2/X4's above 300htt Easily when compared. This is using the Same cooling to rule out if a CPU not cold enuff...
As for a CPU slowly going down Hill,, Add more Volts to the Vcore for the Same clock you were allways at..If it helps and becomes stable is most likely CPU losing its gradability.(degradation).Some cases it can be that Mobo's PWM's may be getting weak after prolonged use and not keeping Things stable when booting.
Theres so many factors involved as we venture to install unlocked chips . This alone is a 50/50 chance the Mobo and Chip is up to it. If the CPU unlocks and the NB dosnt go above 2600mhz with 1.3v on the NBvid , It most likely is a weak CPU IMC.. If one has a spare DDR3 mobo, that unlocks ,, you would then test that same CHip again.. If it unlocks and is 100% stable you have a weak Mobo or DDR2 IMC but the DDR3 IMC would remain strong.
In all the simple of things just takes a little tweaking to find out.
If you Try X4 Air/Watter @4300mhz @300HTT... Its not so easy( at least what ive seen)..The extra CPU load and use of Onboard SB750(Sata Raid 0) makes it a little Harder.
I keep my HTT down around 220 or so for 24/7 on this Mobo for reliability reasons. I know its not the best Clocker and some Mobo's will die real fast when pushed up to much.
