My two Quad Q9550 are overclocked to 3.8 gig and each has a 260/216 video card they are overclocked as well. All systems and video cards are optimized also.

I get the No work available response and the exceeds the 500 per day quota. But I am completing in excess of 700 work units a day as a matter of fact I uploaded 721 work units in one shot in under 24 hours and still received the no work reply. Using Boinc 6.2.20

Taking a quick look, it looks like you have a ton of error returns on a couple of your machines. I suspect you have over clocked too much.

FYI BOINC will limit work when there are too many error returns.

They are the rejects from Raistmer's opp Killing VLAR CUDA workunits.

Computer error for a Cuda WU.

I posted about them earlier and was informed about the Kill command.

What would cause this error?

You must have had a bucket-load of "shorties" to crunch through that volume in 24 hours; this can't happen regularly, surely?
I'd suggest enabling Astropulse (optimised, of course). That will cut down the numbers and increase the RAC (if the latter has any relevance).

Actually you didn't 'complete' 700 work units, maybe 1/2 of those were errored out and returned after 1 sec of crunching ( autokill of troublesome VLAR work units it would seem)

The BOINC system is working as designed to prevent a rouge PC from going haywire and hogging / aborting tens of thousands of work units and the resulting bandwidth.

It's not the systems fault that YOUR PC decided to abort and return 1/2 the work units uncrunched, and then got restricted on new work untis. It's supposed to do that.

In the overall scheme of things it's not a problem for you either as your cache will refill as it gets a normal mix of work units. 200-300 per day would be the normal turnover for your rig, and well within your 500 limit.

Thanks for the replies guys I mis-spoke it should of said that there were 721 returns reported that day not that it completes 721 units a day.

Sorry for the wrong info.
