How do you only allow it to run on one core only? I think i'd like to run one on both of my quads to see how it's gonna do.

While the Challenge is still quite some time away, we wanted to prepare everyone for the intensity of doing LLR testing on such large numbers. PSP LLR is currently testing n>7M which can produce a 2M+ digit prime.
This Challenge will definitely live up to its definition...it will truly be challenging. It will be like running a constant "stress test" on your computer for 9 days straight. Solid, well cleaned and cooled computers will be a necessity. Good hardware will "rule the day".
As for the psychology of the Challenge, patience will be the virtue needed if you wish to participate.  The average WU is 50 hours long (range: 28hrs to 100hrs). So, you can see the importance of having stable hardware.
------------------------------------
ATTENTION: The primality program LLR is CPU intensive; so, it is vital to have a stable system with good cooling. It does not tolerate "even the slightest of errors." Please see this post for more details on how you can "stress test" your computer. WU's will take ~30-35 hours on fast/newer computers and 50-90 hours on slower/older computers. If your computer is highly overclocked, please consider "stress testing" it. Sieving is an excellent alternative for computers that are not able to return valid LLR results.
Application builds are available for Linux 32 bit and Windows 32 bit. These applications will be sent to 64 bit clients. As with all LLR application projects, there is no advantage of 64 bit over 32 bit.

I should be good to go. Everything is running great so far. If necessary i'll back off a little on the OC in the Beast. Camelot3 (Q6600) is OC'd to 3.15 and has been for months. Cooling on that one may be an issue though. I may have to put a fan blowing into the open side of the case. Or maybe just order a new case. I really like the antec 900 but I think two of them in the room with all the led's might be a little much. Might have to do some shopping. Any suggestions?

One I've been eying is the Thermaltake Mozart http://www.overclockercafe.com/Reviews/cases/Tt_Mozart_Tx/index.html but I'd like someone else to try if first

Now down to one Intel Core 2 Quad Q6700 that's in a tiny case and overheats if I actually try to use all four cores at the same time. On the other hand, it makes for a very nice home theater PC
