I have had some trouble with my pc ever since I put in a bad ddr3 dimm and at the same time got air in my waterpump/coolingblock on the cpu.

Now, when I disable the cool&quiet, APM (on or off, cant remember the default) and turn on the LLC the pc dont even boot up windows. Im lucky to get a post. Now, in the search for an error I OC´ed my FX8320 to 4GHz with only the multi. No Volt changes or anything and it works like a charm.

Is it more possible that I have broke the motherboard in this case or would the cpu still be considered a culprit? Dont have any spare parts to test with. Kind of expensive to buy the wrong part unnecessarily

What parts are you using?
I would put some nylon washers in between any cooler-mounting hardware and the motherboard pcb.
It could be all sorts of things: CPU temp,standoff shorting,cooler mounting shorting..bad RAM timings..

Im running a FX-8320 on a Sabertooth from Asus. And a H60 to cool the cpu, so no extra mounted stuff on the MB. All my problem came at the same time. What sucks is that 2 errors occured at the same time. Leaving me with a hard to find conclusion.
For one, it was the bad DIMM, have thrown it in the trash now. At the same time the pump started to act up, had gotten air in it while vacuuming the rad.
Imo, I either burned the cpu or shorted the mb.

Before all this I ran it @ 4.5-4.7GHz at all times. With Noctua fans on the rad and 2 in the roof. Plus 2 140mm´s in the front. 1 120mm in the side panel and one next to the PSU in the bottom of my Fractal Define R4. Also, my ram was running at 1.65v @1866MHz on 9-10-9-27 (2T). This worked for months. almost a year. And then a stroke of bad luck with the ram and cooler, both at the same time, left me where I am today.
As soon as I change power settings the PC will not boot. But I could raise the multi, now running volts and other stuff in stock mode except cpu via multiplier @4Ghz.

Would have to kind of disagree. Have had it stable on 4.7GHz for moths. Never going past 60c, usually found my self around 55-58 when I played games like Crysis 3 or BF4. I use 2 Noctua 1500rpm high static pwm fans on the H60. What I think happened are 1 of 2 things. Either the damaged DIMM shorted out my board or the air trapped in the cooling block on the H60 made the CPU overheat, damaging it somehow.

Right now I am running it in 4GHz, stock volt and fbs @200, the ram @1866MHz. Works without a hitch. But should I turn off Cool&Quiet, off APM or on LLC, then the PC will not boot. There will be one beep, then automatic shutdown. I am inclined to think that I damaged the VRM´s somehow?
