I would like to get your opinions on the old C0 Stepping vs the new D0 Stepping.
For reference here is the errata(error) documentation:
i would go for the D0 i had the C0 and it was good but the D0 is a much more stable and higher overclocker if thats what you are looking for. my C0 only clocked to 4389mhz @1.550v (not stable might i add)yet my D0 will clock up to 4720mhz @1.550v and was able to run for over 30min at 100% load till i shut it off as i was just testing it i would not do that for long. i no all chips are diffrent but this is a large jump in stability
