I just PM'd a good friend here with an experience I had today and thought I'd post it here so others could maybe benefit from it. I must say I was surprised...never too old to learn
I picked up a Q9950 up at Microcenter yesterday to do a review on LGA 775 quads vs P55 quad...the 1st one I got was a L845B batch and I read at XS after I got home that it is a crappy batch, luckily I did not open the box, so I drove 30 minutes back and pick up a new L847C batch, yes the "C's" are out. the VID is a nice low 1.2125 v
Now the strange thing is I put it on two boards, X38 and the DDR3 Giga EPT45-UD3P and it failed the RAM every time if I go above 450 FSB. Now I know the DDR2 Giga EP45-UD3P is a killer when it comes to clocking 45nm quads, so I took another drive to Frys to get one....and wholla, I'm priming while I type at 471 x 8.5 (4 G's) with only 1.25v in CPUz and temps just touch 50C on air with and old crappy Thermalright 120 (not the extreme version)
Now the moral of the story is do not in the first instance blame the CPU if you are having trouble with your OC, your board could just not be the best fit to yield a good OC
Then those who are looking still to get a good Q9550, look out for the "C" batches
