Prime95 is a very useful stability tester for overclockers. When you run a "Torture Test" it will indicate whether or not your PC is stable. If you can run this application for at least 24 hours without errors than you can assume that you have a stable overclock.
You should have no trouble keeping it at 60°C overnight. It's not necessarily the best idea to run a C2D that hot 24/7 for an extended period of time (pre-G0s, that is) as 55°C max. is recommended for long term overclocking. Still, for the period of time that you're talking about, there should be no adverse effects to your gear.
Stability testing is a very subjective thing. Generally, even the most die hard of testers will accept a 24 hour test as proof of stability. Others say 6 or 10 hours. Personally, I don't go nearly that long, instead doing a shorter test and consider things fine unless I notice instability when running other applications.

Would you happen to know the safe limits of an X2 opteron 175...
...would a 24/7 OC with load temps @ 49-51ish threaten the chips longevity seriously?

I think the juncture point is 65*C ???
I'm much better informed on Intel than AMD, and I honestly don't know the recommended load temps for dual core Optys off hand. I suggest you check out the AMD CPU forum for more info.
Hey, I am starting to overclock using this software to stress test my cpu. I have read that when there is an error that it is unstable and needs to be tweaked, but what about when only one core consistently fails? Do I need more voltage? I am pretty sure this isn't the limit of my cpu because it is a qx9650 and only at 3.4ghz
That is usually the case, needing more Vcore make it stable. There are many things it can be if that doesn't do the trick. It's probably easiest to do a search for your motherboard and see what others have done and had issues with. There is a lot to overclocking and learning what each component is capable of to get the most from your system. Know the limits and watch your temps, that's the most important part.

PrimeNet 4.0 offline for repair ....
One of the disk drives in the PrimeNet 4.0 RAID array has failed and we have the system offline until it's replaced and the data rebuilt. No ETA yet but guessing a day or so. Email me at primenet@mersenne.org to follow up.
MegaOption, mind adding it to the first post upload so we can have it next to the regular version?
I think its a good idea because these days Ive noticed that it makes a big difference to use an x64 stressing tool in order to achieve full stability in real-world scenarios in a x64 environment. testing with an 32bit/x86 client on the x64 environment is insufficient.

1) Bug fixed in smart affinity on hyperthreaded CPUs.
2) Bug fixed in setting a thread priority other than 1.
3) Off-by-one-bit bug fixed in the benchmarking of trial factoring.
