Remind me again why I can't download 10 days work in advance, and I get the this host has reached its maximum work in progress messages?

The trust model really needs to scale with successful computation returns. Good host? lots of work for you. Bad host? You get less then down to nothing.

At the very least don't give me an option to check "10 days of work" when this never covers even one.

Hello All,

Our next number 1 crunching CPU exist!

Happy crunching


If priced at $450 this would be the best processor for 24/7 computing in a very long time. Already the best price I can get on a 3900x in my area is $570. I missed the boat for even moderate availability so now Microcenter is over MSRP.

I was going to underclock/set TDP to 65w anyway, this will save me at least $100. Even more if it hits at $430.

We have had molecular oxygen in our atmosphere in significant concentrations for roughly 2.45 billion years.

If someone/thing was in the galactic neighborhood anytime since then and bothered to look we would be an interesting observational target.

It seems there is a general openCL issue with the new 5700 series of cards with compute tasks validating, here is a related thread I have been watching over at Einstein@home.

Hopefully fixed soon by AMD.

Make sure any requested GPU clock offsets are set in 7 Mhz increments, as far as I know this is a architectural limitation. (memory clock offsets are unaffected by this). EVGA PrecisionX on Windows does this automatically, but if you want to sit in your command line bunker be sure to take this into account.

I came here to figure out why my quad 780 system video response was so slow and power usage down so much. (Creditscrew down too, but with any change at all from this project that's a given.)

But look! Its another poorly optimized application thrown into the wild WAY before its ready! You should merge Seti@home and Seti@home beta because there is obviously no functional separation of the two.

It's very obvious that keeping GPU's optimized and busy is about the lowest priority that anyone in the project administration has. Relying on volunteers for everything, no stable work, no reasonable work cache to buffer yourself against no stable work.

For something that probably has the largest impact on the total amount of computing power of this project, its remarkably given little weight and concern.

Darth Raccoon makes a good point.

You will need some command lines for that 780 to get it running at it's best. (if you don't already have one)

I don't remember what mine was for the 780.

Mike would know what the best settings would be.

What's the best command line settings for the 780?

Don't run SETI without a backup project set to a low priority if you are trying to keep your computer busy at all times.

SETI could mitigate this with reasonable work queues, but it seems those haven't been adjusted since the advancement of GPU work. ( I run 3 tasks each on 3 of my GPU's and SETI wont let me keep more than a couple hours of work for my machine. When you combine this with how very often SETI has no work available, it makes a good case for a backup project.

I like Einstein so that's what my GPUs are running now.

1) Don't trust manufacturers specs

2) 240v AC direct for a case fan? Why do you need AC when your power supply gives you a nice 12v DC source? Or are you just saying your computer is connected to 240v ? In this case your power supply would handle the conversion just fine and still give you 12v DC at your molex or fan plug.

3) For a fan comparision, sadly martin has let his domain lapse, but just browse here.

Another good maker of very high CFM fans is delta, there are high noise levels to go with them, but on a noise/CFM basis when you need a high CFM they do quite well.

For my 780 SLI and i5 2500k system I:

Installed the lunatics optimized apps for GPU AP and GPU v7

I did NOT install the CPU versions.

I run two work units per card.

Its important to leave 1 CPU core free for each GPU work unit. So with my quad core I don't do any CPU only tasks.

From the picture you posted and the orientations of your fans you seem to have a slight issue...

rear case fan seems to be trying to exhaust air out of case,

going inward, your back cpu cooler fan seems to be trying to pull air the opposite direction, into your case.

the fan in the middle of your cooler seems to be going in the same way, pushing air to the front of your case.

so your setup looks like this.

<<< >>> >>>

You might achieve better results lining them all in the same flow direction, as your back two fans are just fighting to pull the air in different directions. You want to take the hot air from your CPU and put it directly out the back of the case as long as your case isn't backed up to a wall (keep a good 6 inches at least away from the wall)

To do this, turn your CPU fans to point in the other direction.

I have a 750Ti that does very well. The only reason I would not recommend it would be that:

    Larger die Maxwell architecture on 28nm designs look to be in the works and should hit within 1-2 months, I think these would travel up the product stack and hit something in the 765 Ti range with one of the upcoming models.

    Also if you do any PC gaming at all if you went with dual 750Ti's you can't SLI them. The next Maxwell cards up in the product stack should be SLI capable. If you are spending the $ to help others out with distributed computing, you might as well be able to game very nicely in your spare time too.

If you did get a 780 I would advise on a reference (blower) cooler. If you ever wanted to add another 780 the reference coolers would perform better in close proximity. I have two in SLI and my case temps are near ambient, but its a high airflow case.

If you are looking for high overclocks/not looking to SLI/don't care about slightly higher case temps the ACX should be fine.

Posted 13 Apr 2014 by Profile ace_quaker
Thank you Juan and msattler,

The kitties are happier at 90-95% gpu usage with 2 copies per card.

Before with stock apps and 1 per card it was in the 50-60% range.

It looks like my i5 can keep up with no other CPU tasks going. I do have it at a mild OC of 4.2 Ghz so that might help a little.

Id like to make my two 780s as efficient as possible. I had crashing problems before with the lunatics apps with my 560. Are the lunatics apps too old now? Should I try those?

Should I run 2 or 3 copies on each card?

I really wish SETI@home had this statistic like it did with SETI@home classic.

Please implement this.
