So, I am waiting for my Classifieds to return, and in the mean time, I am using the 760s from little brother in Big Brother. They are folding at about 100k ppd. I have a borrowed 760 in Little Brother right now, and it alone is pulling approximately the same ppd.
No over clock on the cards, in either system. The only difference is dual vs single, 4770k vs 3770k, and so on. Any ideas?

Big is running 32gb of Ram and the 760s have 4gb.
Little is running 16gb of Ram and the 760 has 2gb.

From what I have read you should disable SLI for Folding and or Crunching Projects. Both cards are GK104 or at least below GK110 GPUs. Disable SLI and see what happens.

Ah... Dang, OK. Forgot about disabling SLI. It is currently enabled, of course. Will give that a shot tonight.

Hehe. I am going to split the cpu and GPUs into separate loops to cut down on temps a little more.

Everyone needs 3... Why wouldn't one need 3? What happens if one goes down... Then I don't have a backup. LoL.
Also, I disabled SLI. No score change at all. I may have to try a different driver for them.

Currently Folding 4 cards and 1 CPU. 1 780 ti and 1 2gb 760 in Big Brother, and Little Brother is running exactly as stated in my signature (2x 760). Little is Folding both cards on Core 18s and the CPU (130k ppd). Big is Folding 2 Core 17s, no CPU (143k ppd). The PPD is strangely close, when i previously was getting 500k ppd with two 780Tis. Why am I unable to get the 250k on the GK110 when I was easily pulling that previously?
Also, I am considering switching up to two 780s on the Big Brother Mobo, once I get the Extreme Brother moved in (3930k on a Dark Board). Is there a Substantial difference between GK104 vs GK110? I am going to be looking for cheap reference cards to run on the Big Brother that is refreshed, so that I am still outputting a good PPD.

I have no explanation really... it's just weird that your GTX 780Ti is not producing as it should. With Core 17, it should do around 230-260K. Heck, with some lucky (and rare) 9406 WU's each of mine are pulling up to 320K! Did you try running the GTX 780Ti alone? Just pause the GTX 760 and see what happens. If that doesn't help, try pulling the GTX 760 out completely. Final resort, try a clean driver reinstall...

Will give that a try now. I am pulling 2 sticks of Ram, the 760 and a few cables to test out the new system, so I will give that a quick try as well. **Edit** Dropping down to the 780Ti only, it dropped to 97k. I will try pulling the 760 once the current project is complete, and will test with it completely removed from the system.

You should definitely run with SLI disabled. One thing I have noticed before with SLI enabled and Precision running the GPU usuage was very ragged. With it disabled, GPU usage was nice and smooth where it should be. Just all around better performance when folding.

I do not have SLI cards in, only the 780ti and a 760, so that isn't the issue. They were running strong before I sent them off for a while. Now, I can't figure out why my PPD is so low. Either way, they are working, and working fast, so I am not worried about points as much as getting the units completed.

Just the first thing I can think of, are you allotting a CPU thread/core for each card in the system?

Yes. I definitely have the threads/cores alloted for the two working GPUs. I tried a fresh driver install this morning, so I will see how they are working this afternoon.
The 760s in both systems are getting the same time per fold and nearly identical ppd, its just the 780 that is bugging me getting so low, when I have never had this issue before.

What TPF are you seeing for what WU?
What is the GPU utilization %, power %?

I forgot to glance at utilization, but 2 min tpf on the 780ti and 6-8min on the 760's (both systems).

I'm assuming that's project 9202. 2 min tpf should net you more than 245K PPD on 780Ti alone. You may just have bad PPD reporting, or some kind of stability problem that causes WU's crash or keep reloading in between. Did you check your folding log? Do you see any errors, warnings?

I did not get a chance to check the logs, but I don't think there were any pauses, rollback, or hiccups, as the projects changed consistently. I did not think to check the Logs, but I fully uninstalled [link=mailto:F@H]F@H[/link] (due to it losing the connection to the server and I couldn't get it back) and now the system is starting the process of the first WU's available.
Will report back what I can, when it becomes available.

No significant change. it is still running about 165k ppd. Eh, I will figure it out this weekend.

With 2min TPF, you should see 245K PPD. So, there is something wrong... Possible explanations: 1) It was an old WU, downloaded some time ago, paused and restarted later 2) Your internet connection is waaaaay toooo slooooowwww... 3) Software is somehow reporting wrong PPD I'm out of ideas otherwise...

it is chugging through work units like they are cool, so it should be an incorrect reporting of PPD. Right now, it is a 9202 (90, 0, 54) where as the one above was 9202 (117, 0, 83).
I have no idea.

Now, er get to the fun part.... Down to 25k a day, and the GK110 work units are running at 21m 58s per fold, while the GK104 is going at 53m 15s per... I am not going to fold if it is going to take 2 days per unit and then not report the proper Points. *edit* deleted the FAH_Core 17.exe and got the points up to 100k+ but Little brother is still putting out much better PPD than Big. I am going to let it run for another hour or so, since the points are slowly climbing and the TPF is slowly decreasing, and see what happens.

Now, the GK110 is folding at 5 min 2 sec TPF and the GK104 is at 1 hour 58 min per fold... So, I am just going to shut it down and wait for ideas, once the GK110 finishes. no point in letting the GK104 work for 5+ days on one single WU.

I haven't been following this thread all that closely, so these questions may have been covered already:
Which client version are you running? If it's 7.3.6, are you getting the PPD and TPF from the client, the logs, or HFM? Every version prior to 7.4.0 had some bad TPF and PPD calculation logic. If it's 7.4.4, then I'd trust the client's figures a lot more.
