Great news. I already have plans for a new GPUGRID rig that will outproduce my 3x690 rig for about 50% and should do 3mill/day easily, using the new cards that are about to arrive with GK110 gpus. No more GK104 over here.

Great.

Great news!

So, for potential buyers seeking advice, is it already possible to make a side by side comparison between GK104's and GK110's in points per watt?.

We know long run costs are the key factor in the decision. Initial investment will be linked to each buyer location, wishes, etc so it is more subjective.

thanks

I think it would be great if you post this excellent news on the project's facebook wall as well.

Done for facebook.

Por GPUGRID no muestra la proteína que se calcula como Rosetta?
Y GPUGRID no sólo se ejecuta en la CPU? Podría correr tanto GPUGRID en mi Titan y mi CPU.

Why GPUGRID does not display the protein being calculated as Rosetta?
And GPUGRID not only runs on CPU? I could run both GPUGRID on my Titan and my CPU.

Pourquoi GPUGRID n'affiche pas la protéine en cours de calcul comme Rosetta ?
Et que GPUGRID ne tourne pas uniquement sur CPU ? je pourrais faire tourner à la fois GPUGRID sur ma Titan et mes CPU.

Thank you again for your work.

Congratulations.

My 780 is switching from one WU to another (but just 2) every 2 minutes or so. Any clues?

Welcome to the world of "Access violations".

Been going on since 8.14 was released.

Seems to mostly affect 700 series cards. Something in the apps CUDA code makes it do this.

MJH is aware of the problem but hasn't been able to address it yet.

Make sure you keep at least one WU extra available for the GPU to switch over to so you aren't wasting as many cycles as you would otherwise.

It seems that 331.40 solve it!!! I install it this morning and NO CHANGES SINCE THEN!
Now I´m happy with the beast. And man.. it´s fast.

I have to say that i´m VERY pleased with the 780 now. It´s overclocking very well and crunching very fast. I was about to buy another 690, but wild hold for a 790 instead, that should do 40-50% more work.

Indeed it has. 780 is around 30% faster than 680 Firehawk.

30% ...... maybe
But pricing policy nvidia is relentless ..
Cheapest NVIDIA GeForce GTX780 that I found for the price of about 570 eu and more .. One (I) can buy using GeForce GTX 680 for the price of 200 eu cca ..
It is a ratio of about 600EU - 200EU
6xx Series nVidia will still the most advantageous HW long for counting GPUGRID ..
nvidia cards 7xx is most preferably completely ignored, and the generations to come maxwell from NVDIA be maximally 40-60% faster than Kepler 6 xxx but will be expensive 800-1000 usd. and optimization in GPUGRID for maxwell is nowhere in sight,
So my analysis is that the next two years will be about most preferably count on GPUGrid nvidia 6xx cards .. because Maxwell does not come so soon and will be expensive.

Its all a matter of perspective and how much cash you got. For me, 30% is a large enough # that its justifiable. If I can knock several hours off a WU, that's huge.

If one considers only price point, than yes, the newest is never the best. I will be waiting to buy when Maxwell is released. Not only because of the time difference between hardware release and app release, but because im really hoping Haswell e will offer an 8 core.

My experiences with the 660´s are that bad that I only will buy 7xx cards from now one. My Asus 770 does great, runs cool and almost every type of WU runs in one go, that means no interruption by the app as termination to avoid error. That saves a lot of frustration and lost crunching time. That is also a point of consideration than only cash. But of course cash is an important decision maker, that is the reason I don´t have a 780 or Titan yet.

Now that the v331.40 beta driver has fixed the access violation error of the GK110 cards (GTX 780 and GTX TITAN), I'm planning to buy a GTX 780.
For all those who are planning to do the same thing: it might be wise to wait a couple of days, until AMD release their R9-290 and R9-290X based cards, as (according to its specs and the leaked benchmarks) these cards could/will be the competitors of the GTX 780 and the GTX TITAN, but their prices could/will be lower (around $600), thus they will force NV to lower their prices a bit. (as they already did it with their lesser cards).

Rumor has it that nVidia might release the Titan Ultra at Montreal the 16th or 17th of this month and lower prices too. It's supposed to be a fully enabled GK110 with 2880 cores, there's also mention of a new Tesla K40 with the GK180 (is that the Maxwell?) but still with 2880 shaders. But, as I said, it's still a rumor, but a reliable one at that, I guess we'll have to wait and see.

I am buying a 780 next month. But I have a question about the fan.
GPU´s are casing heat. My Asus 770 has two fans and runs really cool.
Now the 780 and the Titan, from EVGA and Asus have only one fan. This is strange to me as I would expect these cards run little warmer as they use more Watt and Watt is heat. So why don´t they build these cards with two or even three fans?

The single fan cards have more what's like a blower, they vent the hot air out the back. The twin fan models vent in to the case, not so good for other components. If you can have a case fan blowing in fresh air on to a blower type card, I think that's the best way to go.

Thanks again Zoltan.
I forget to look at Asus site I only looked at my 3 suppliers and they don't have them (yet).

Flashawk, I understand what you mean, but my experience with the 770 (twin fan) is good. I have had a temperature reading sensor in it, just in front of the second fan and that air was quite cool 54°. Two case fans blow cool air in and 3 are taking it out. The card is very quit as well and that I like as well.

What do you guys think of MSI cards? They are a bit cheaper in the Netherlands and plenty available.
My first choice would be EVGA, followed by Asus.

Greetings from TJ

I have a lot of MSI cards and they've been great. It so much depends on the model of ANY brand card, some have great cooling, some not so good. Newegg reviews are helpful or ask about a specific model.

With excellent cooling, would you put in side fans? Must they blow in air or push out air? Top fans?

Stacking those multi-fan video cards has resulted in unfavorable results for me. I have already "cooked" one multi-fan video card in a stacked configuration with an open case panel (they were Gigabyte video cards). What I now do is I put the multi-fan card on the top and bottom and a "blower" card in the middle. That configuration has yield acceptable and workable temperatures, however the middle card will generally be hotter by 5-7c. This occurs with the side case panel off at all times.

If you want to use the side case panel where the side panel fans facing or near the video card, for multi-fan cards the air flow should be directed towards the outside of the case, or air being pushed out of the case. If the air flow is directed towards the multi fan video cards, you run the risk of the video card and the case side fan "fighting" each other as air is being directed towards (case fans) the video cards while the video cards are venting inside and usually directed towards the case side panel. This may result in the video card not receiving proper ventilation and a very hot video card. For those "blower" cards, either way could work and I have found this to be best determined on a "case by case" basis.

I totally agree with what skgiven stated above "...with excellent case cooling &/or an open side panel." Having an excellent case cooling solution can help you mitigate potential heating issues with all your computer components. I would add that prior to purchasing a new motherboard I carefully review the amount spacing between each video card on the motherboards, and sometimes leaving an empty PCIe slot to aid air flow may help prevent "cooked" video cards.

I have a problem like this with my GTX Titan and GTX 780 with driver 327.23
My GPUGRID WU are not switching from one WU to another but they are stopping working every 2-3 minutes (access violation). After 1 minute the WU starts again.
Schould i change to the 331.40 driver?

Yes please do it. 331.40 improves a lot the stability on the GK110 chips.

we have received news that the gtx780 had a huge price drop. Around 100 euro less.
