3.Yes. Don't run Seti cuda all the time. Sometimes once or twice in 8 hours drops core to 405MHz. Have looked at error message Boinc say computing error.

Errors can happen when PC is running without other use.
Seem to start with .38 + 27X.xx drivers
Have MSI Afterburner installed with above profiles.

You do realize that the Sandy Bridge motherboards have a lot less PCIE lanes so that you can't use as many video cards as you could with say an i7 970.

Just a thought.

"Dual channel" and (I assume) "triple channel" is marketing-speak for two (three)physically and electrically identical modules. There's no need to buy "special" dual/triple channel modules as long as the ones you get are identical (i.e., same model/part number).

Have you considered that you're likely overreacting? We're currently in our 3 day outage window and before your post, things were working just fine. As of the time of this post, we've been without new tasks for around 16 hours, don't panic.

What most north Americans don't consider is how their decisions affect us this side of the pond.
Since I retired, to keep costs reasonable, and to relieve some of the stress on Seti, I now only crunch when I am up and about. Approx 16 to 18 hrs a day...

JPM, you can still crunch. The idea behind S@H was to use spare cycles. That means running in the background when your computer is on but idle. For example when you go grab lunch or a cup of coffee. If you use the program as originally envisioned then you can still crunch and only burn the electricity that your computer will burn anyway.

What's the best way, very specifically, to transfer un-crunched WU from one machine to another?
Thanks,

You can transfer the identity of a machine to a different machine, including un-crunched work.

If you have a slow machine with tons of work, and a fast machine that is empty, you could actually swap identities.

What you can't do is take some work on machine "A" and give it to machine "B."

One form of widespread cheating in SETI Classic was to have one machine download work, crunch it on multiple machines offline, and then give it back to the original machine to return -- making that original machine seem mind-bogglingly fast.

yes it is the monitors. Imac has a different setup in pixels...don`t remember what it is , but my professor explained it to me because I brought the subject up to him also.
