My GTX770 cards are generic Chinese imports.


There's your problem... they aren't actually GTX770's. Einstein is reporting they only have 128 cuda cores.

The GTX980 does quite well in the Folding@home benchmarks.

http://www.anandtech.com/show/8526/nvidia-geforce-gtx-980-review/20

Wow! Than it's possible that the GTX980's performance improvement over the GTX780Ti will be in the 25-45% range.

Well if I read the graph correct then its 6.2 and the 780Ti is 11.

Double precision performance is lower but SP which is most common for folding is higher.

For the price of the GPU EC2 for 1 year I could build and power a new system for over a year.... Is it really worth it?

I had a 460+650ti in a system and once I got it set up right (both monitors had to be on one card) it worked just fine...
The only thing I can suggest is I would try a clean driver re-install.

I was using the older drivers for folding@home performance... Guess now I'm running here again I can update.
I always leave cpu core open for GPU... Also set GPUgrid to use that open core fully for better performance.
The 700 series gpu's are much better performance than the 600 series so I'm not overly surprised. The 650 and 750 also have a 128bit memory bus so it could be that slowing things down as well if its a big protein.

I was running short units in 3 hours with the CMYBKIX tasks on my 650Ti so I thought I must be able to run the long units in under 24 hours... boy was I wrong! 35 hours in and only 79% finished. Whoops guess I learnt my lesson!
Back to short I go :)

Sorry I thought I had replied but it appears as though I didn't.

Thanks for the answers,

There would be a lot of connections but each connection would be a small amount of data. Its the same amount of data overall from what it sounds like... just sent over multiple connections. I'm not sure what the net result for server load would be though.

I see over at folding@home they are testing a new core that is a streaming core (it sends data to the server every frame instead of once per wu)

I was curious if gpugrid was looking at doing a similar thing? It sounds like it has multiple advantages - all usable GPU's can be used without worrying about it being too slow (since data gets returned much quicker), don't need to worry about waiting for wu's to timeout if lost/person quit, no deadlines to worry about for slower GPU's.... There may be many more but those are the ones I know about.

I'm having the same issue... Was this ever fixed?
