Your intensity dramaticly affects the stability of your rig.. So does temperature. If its stable at the lower intensity I suggest staying there.. However if you have a card where you can lower the voltage on it, I will tell you that it dramaticly decreases heat and increases stability. Defaults on my msi 7950 voltage were 1.188 and I run them at 1.050 with a higher intensity now. A well tweaked bat file makes all the difference as well as good hardware.

I hope that my most recent adjustment of lowering my thread concurrency, on top of lowering my "I' settings, will allow my rig to run 24/7 without issue on hashcows.

Interestingly enough, I did see a very slight bump in hash rate after dropping my thread concurrency.

Thinking back, when I was running at I:20, that not only increased stales and temps, but IIRC it caused a full lockup after a few hours, at some point along the way.

My cards will undervolt, and I have them set to run at .900 through cgminer. Cgminer does not report the voltages accurately, but I did some internet research and found a post somewhere out there stating that despite the reporting inaccuracy, it will actually adjust the voltages. I intend to buy a kill-a-watt for testing so I can go through each card and adjust and see for myself in case that info is not correct for my version, since I upgraded to the newest that will run scrypt (3.7.2 for windows).

I have played around with the engine and memory clocks (using a .7 to 1 ratio) until I found the "best" hash-rates for my cards, although I may go through them again and see if I can fine-tune that some more, since I can't remember what intensity or thread concurrency I was at when I set them last, and also I was making changes in 50 Hz whacks.

My temps are pretty good, right now I'm seeing 68 to 70, and even when I had the "I" cranked up, I was seeing 75 to 77. All of my cards are on risers in a milk crate and each has dual fans built-in, and I also have three more big 5" a.c. computer style fans controlled by a rheostat blowing down into the cards.

Noob Question to the pool runners about immatures...do we get paid or not get paid on those until they mature? If we wait until they mature then I would definitely want to see a record of all immatures, beyond the 30 round ledger. I always see those tag coins fall off of the list and have yet to see one mature before doing so. Seeing a full record of coins like that would be nice, since as is stands, we have no simple way of knowing what happens to them once they disappear off of that list. I guess that I could collect them and exchange them myself, but I am trying to keep things simple, at least for now.

EDIT: Well the problem occurred again. I brought up the task manager and then tried to open a browser and locked up the rig so I took a couple of pics with my camera. Not sure if this will help out, but maybe someone can tell me what is going on somehow.

I noticed that the CPU was actually pegged at 99% while cgminer was still producing messages, which I did not notice before. The last message before cgminer stopped producing messages was "stratum connection to pool 0 interrupted", although I still had an internet connection to my netbook, and I had not locked up the computer yet.
It's possible that the wired internet connection that is connected to the miner was messed up somehow, so I recycled my router before rebooting and connecting to the pool.

Hmm, this is frustrating me. If anyone has any insight on what could be going on, that would be great.

EDIT: Figured that I would post up my most recent config:
(I know gpudyninterval does not do anything for me, I just haven't deleted it )
