When I built my new rig with dual Xeon I was rising past 30k daily RAC and the graph looked like it'd peak at about 50k but when I installed optimized Lunatic files, the RAC dropped to under 15k and seemed to flatline there.

I checked the results, there were very few errors (about 1.5% of total WU returned) so it couldn't be from too many errors.

It's almost as if optimized files are going through too fast, getting me less credit for time and with bandwidth issue still on, I can't get enough WU to keep my machine from idling about 20 hours a day :/

read up on this Forum. IIRC there is a problem with the newer nVidia drivers

Yes it's not the Lunatics Opt. Apps but the drivers that you're using that is the problem. When your monitor goes to sleep so does your video card so either set Windows to not let your monitor go to sleep or go back to an older (pre 295.xx) driver.

Cheers.

Looking at the task list on Eric-4GHz's host i see no evidence of the Sleeping Monitor Bug, no -177 errors on the Stock Cuda app, and no extended runtimes or errors on the Optimised Cuda app, so that isn't the problem,

Looks like he has gone back to normal apps .

Is it possible that he used the wrong SSE choice?

I think it is more possible that his computer isn't running 24/7

Which it would need to to get the RAC he wants.

I must of caught 1 from just before he changed back but it showed signs of the video going to sleep.

Cheers.

{edit]It also hasn't been crunching very long at all either so it wouldn't of had enough time to get a near constant RAC.[/edit]

Are you sure that your machine was not just having issues getting work to process? Recently that was a large issues. I had several machines run completely out of work for more than a day. I noticed your system currently has 380 tasks to process. My dual Xeon E5645 processes about that many on the CPUs in a day. I have found a cache of 1 day not to be sufficient to maintain constant processing.
