While overclocking does it have to do with Vcore, VTT, or Motherboard QPi

http://en.wikipedia.org/wiki/Machine_Check_Exception
 
Usualy it has to do with Pushing your memory, or Uncore freq, losing timing may help, Make sure your Uncore is 2X your memory devider 1.5 for 980/990, and uncore freq is around 3000, posting your template may help.

This is after I adjusted some voltages. Let me know if something is off. 
When I got the BSOD I had the VTT at +175 and the Vcore at 1.375, ICh at 1.125, I dunno someone said leave your ICh at 1.1 at all times, there's no reason to bump it, people are idiots.  He's pretty intelligent so I took his advice.

any help? or no.

Sorry didn't answer earler, Just got back from Church; Your settings look almost identical to mine on my 920, I did have to back off just a tad for tempature readings as summer aproached, and running 197 insted of 200, did not take anything notacable off my performance, but did give me a little better stabality, lowering my 1600 memory to 1572. My XMS3 was feniky and did not like exceeding 1600, where as my Mushkin did not error even up to a 21X206 for 1644. I did have Vdroop inabled as well as HTad turbo mode. but since every chip is difrent I can not absolutley tell you your fine. But with only 6G you should be able to do a command rate of T1, I needed T2, because I has 12G.

Thanks Kmoore, good idea about backing down to 197 and what not sometimes.  That is a damn good idea, Just like seeing 4.20 all the time :) lol.  But good idea though if I ever have stability issues.  One thing though man about the IOH and ICH.  When overclocked so extreme should I bump the ICH to 1.125 or keep it at 1.1??? and the IOH, with having only 1 GTX 570 but overclocked so etreme on the board, Should i keep it at 1.15, or do what I thought of as 1.2 or should I bring it even higher? whats your expertise on that part?

I belive the IOH and ICH would depend more on the demand on the NB and SB, and would defantly bump them up for SLI, but for a single card, I do not think it should be necessary, For memory issues DimV and VTT would be your concern , and for BSOD 101's, that would be Vcore.

So Far from that machine check exemption I poped up the vtt and qpi than I got the machine check exception which is what I refered to here.  But after poping up the Vcore, VTT and The QPi to
 
1.3875 V core
+250 VTT
1.35 QPI PLL
 
I have been playing games and it seems to be running smooth with no errors or blue screens.  The only thing is the internet seems slow... I do have like 5 harddrives 2 of which are sata II's and what not, Oh wow **** residnet evil racoon city? wow it's about time thats so badass.  lol anyways.   Ya should I pop up my ICH A lil bit?

Can't delete so Ill just add, I put my QPI on 1.3 and my VTT back to +200 while keeping the vcore at 1.4 and its running alott smoother and I think its still stable. I think it was just my vcore* the whole time. Justt needed to be really bumped for a 4.2 ghz run.
