Forceman - my experience with SUM input and error checking is this one:
Without it, my RAM would pass without problems
With it, my RAM would fail within minutes.
Because I actually had a bad RAM DIMM - when RMA'ed the company did a memtest on it and found and replaced the ram within a day.
If it wasn't for SUM and Error checking on P95, then I would have NEVER known it was the ram.
(I did an 11hr memtest and it passed - but yet on the company's PC, it failed within minutes -> this is what the technician said to me over the phone)
So if you are getting rounding errors, and normally the: 0.5 expected 0.4 gotten -> that is due to RAM (be it actually faulty ram, or bad settings)
As for that error you are getting....that would mean a bad OC - you shouldn't be getting a SINGLE worker stopping, even with those settings on.
As for the OP: wgstrick
-IBT to determine QUICKLY if you are on track with an OC.
-8-12hr prime if you want to determine stability
-24hr p95 to determine close to perfect stability
-Folding for over 8hrs to determine maximum stability (this one I recently discovered lol - I've been stable with a 24hr prime, yet my folding made me BSOD
