Dr. Pande,

Can you also move the P10467 and P10469 core 17 work units back to beta only for Maxwell?

They are failing on my GTX 750Ti cards with the same 'Force RMSE error' that was crashing the P13000 and P13001 work.

Confirmed for 10467, 10468 and 10469.

Edit: Can you fix hfm.net to? It show 0 points and core unknown on 78xx.

HFM is a 3rd party app and as such is unsupported by PG. Which version are you running, the latest version is 0.9.2. If you still have problems or are already upgraded I would suggest contacting the developer - harlam357

HFM.Net is not the problems, ps running 0.9.2. This is http://fah-web.stanford.edu/psummaryC.html

Just a quick anecdotal update.

As of 1:30 PM Eastern.. I'm now getting core 15 work on my GTX 750Ti cards - rather than the failed core 17 work I was getting.

Version 7.4.4 client on Windows 7 systems with the GPU slot set to normal and the 340.xx video drivers.

I was issued a P7621, a P7622 and a P7623 work unit - and all seem to be Folding normally.

Still wish I could get back to the successful core 17 Folding production I had two weeks ago, but at least now I can be of some help to the science.

Hi, I'm having some issues getting work since last night. I have restarted the machine, as well as tried removing all flags and no change.
I keep seeing "Empty work server assignment" I can ping the server but no work.

Any help would be appreciated.

I have picked up core 15 on all four of my 780 ti's with the advanced flag, I thought things were going to stay the same for kepler, I'll go to beta flag now and see what happens.

hi thanks what ever you did the 970s are folding on beta now im using 344.11 drivers

@johnim that's good news, but if you run beta you may get one of the problematic WUs unless they have been completely blocked for Maxwell users.

FYI, 10466-10469 should no longer be assigned on Maxwell at least in fah and advanced:

Let's hope that whatever c17 projects are left are OK. I guess it's normal to start getting c15 units too now that the selection pool has been reduced.

We all wish that.

Core_17 uses some features which were not needed by Cores 15/16. Given a choice between WUs that do fold and WUs that do not, you're probably stuck with cores 15/16 for a while. There seem to be strong reasons to blame the drivers for not supporting the features they're supposed to support and nobody has identified drivers which work. Even if somebody says I'm successfully using drivers xxx.xx, results seem to depend on which class of GPU you're running, perhaps on which version of the OS you're running, and possibly on other factors.

At this point, there is no reason to believe that we're looking at a bug in the Assignment Server code. Rather, as changes were made to minimize the impact of the real AS bugs, attention was focused on problems that were already present but which had remained "under the radar."

Unfortunately, when dealing with bugs which might be in the drivers, which might be in the FahCore, or which might be in the latest hardware, it takes time to isolate each problem (since there may be several) and test the validity of the fix. If all of the bugs are in the FahCore (which I doubt) then Stanford can fix them. If some are in the drivers or the hardware (which I suspect), all Stanford can do is (A) Wait for NV/ATI to create drivers which bypass the defective sections of the hardware,or (B) Wait for NV/ATI to fix their drivers or (C) Rewrite segments of the FahCore to bypass the errors encountered when the drivers produce the correct results.

Note that "(A)" presumes that issuing a recall for defective hardware is not on the list, even if the automakers have sometimes used that option.

22:57:47:WU00:FS01:0x17:Project: 7814 (Run 57, Clone 0, Gen 14)

Running fine on Maxwell GTX970 now

Stock clocks (1076/1753), Win 8.1, Driver 344.16

More data for the diagnostic team:

My GTX 750Ti cards have all picked up P9201 core 17 work units. So some core 17 work is still available to my Maxwell cards - and the work does complete!

If it helps, in each case it is running on version 0.0.52 of core 17.


The configuration on all three systems is the same - version 7.4.4 client on Windows 7 systems with the GPU slot set to normal and the 340.52 video drivers. The GPUs are at stock clocks and I am not SMP Folding on these systems.

Also, two of the systems are Windows 7 Ultimate 64-bit and one is Windows 7 Professional 32-bit - yet they all seemed to be reacting exactly the same to the failed P13001 and P10467 series of core 17 work.


The only other factor I can think of - from the donors side of the equation... is that perhaps a Windows Update fouled things up for some of the 'core 17 on Maxwell' Folding?

It's been about two weeks since I hit my peak Folding day. I looked at one of those boxes - and in that time, I have installed about a dozen Windows updates and about 15 updates to Microsoft Security Essentials. (yeah - I know.. but it is just a Folding box)

If the Pande Group wants to persue updates as being the problem, I could probably cut and paste a list of those updates.

Its not updates. It was an issue with some projects on Maxwell

I've managed to complete the following projects on my 970

22:57:47:WU00:FS01:0x17:Project: 7814 (Run 57, Clone 0, Gen 14)
2:51:16:WU00:FS01:0x17:Project: 9202 (Run 110, Clone 2, Gen 215)
21:47:39:WU00:FS01:0x18:Project: 10473 (Run 0, Clone 194, Gen 44)

But not getting any of the ones that were causing problems.

I'm running all gtx750 & 750ti cards, I haven't changed anything or updated the drivers, and 8 of them failed this week for the first time. I just re-started another one today (removed the gpu slot and added it back), I think it was working yesterday but it might have been sitting there doing nothing for 2 or 3 days. They all run 24 hours a day so I don't always remember to check each one daily. I went from 500,000 ppd to a little over 200,000, although that's partly because of all the core 15s.

Which projects failed? If WUs from 13000, 13001, 10467, 10468, 10469 please dump the WUs and you'll pick up working ones. If others please report them.
