PRCG: 10467 (0, 0, 163) very slow (about 25% of normal)

I've been folding successfully for about three weeks on my dedicated Linux rig (2 weeks since I added another video card) without issues.
Earlier today, I noticed an unusually poor ETA (about 25% the normal ppd) WU on the recently added card and researched it without any luck. Details follow:

First the system:
  • Mobo: Asus P8Z77V-Pro
    CPU: i5-2300
    Video:
    • 2 x EVGA GeForce GTX 970 04G-P4-3975-KR 4GB SSC GAMING w/ACX 2.0+ (factory overclocked 13% to 1190MHz)
      1 x PNY GTX 660 ti XLR8 (stock clocks)
    PSU: 750W platinum rated (system pulls 580W max)
    OS: Ubuntu 14.04.3 LTS
    Drivers: NVidia 355.11
    Other Software: just enough to set the system up for folding: Updates, etc.

    Except for 1 WU with the "slow bug", I have had pretty consistent results so far.
The Log (excerpted, from the end of the previous WU to current):

Issue/Discussion:
The problem is on Slot 3, a GTX 660 ti working on Core 0x17, PRCG: 10467 (0, 0, 163)
It's TPF for this WU has been about 24 minutes the whole time, regardless of attempts to reset it.
It currently is at 56.59% with a TPF of 24:08 (m:s), and an ETA of 17 hrs and 28 mins,
Base credit: 14755, Estimated: 29946, PPD: 17860

Typical PPD for the GTX 660 ti is 60k-70k.

All other slots (1 CPU (only 1 core in use out of 4, lol), and 2 GTX 970's) are behaving normally.

I have paused it and after a long wait (I got called away) started it again.
I have rebooted the PC.
I downgraded the slot to "On idle" to get it to stop, and then started it again (after about a 5 minute wait).

All to no avail.

I have found a few posts with issues on Project 10467, but they haven't had this particular issue.
No overheating, no errors, nothing out of the ordinary - just slow.

The 660 ti is not overclocked - it's at stock reference clocks, it's temps and power usage are normal.

Any information or steps to fix it (if it is indeed abnormal), would be appreciated.

Thank you
- Pete

Does nvidia-smi show a fully loaded GPU ? Are temperature consistent with a FAH load while running this WU ?

Hi Pete,

Unfortunately Fermi and Maxwell GPUs don't co-exist well with each other in the folding world because they have different driver requirements for optimum PPD. My 660 ti works well with 304.128 but if I try the latest drivers the PPD drops dramatically. You will probably need later drivers to get your 970s folding so mixing the two types does not work well. You may find a driver that works well with both but I'm not aware of one. I purposely keep the two types on separate computers so that I can use the driver that works best for each.

Sorry 'bout the delayed response - Black Friday was a riot, and I'm recuperating :D

I was looking at wattages - they were within the normal range. I'm running a minimal linux install and am not familiar with temperature utilities.

Until now, they've been doing fine (using the 355.11 NVidia drivers, as noted above).

Anyway, I just toughed it out, and everything returned to "normal", with the 660 ti pulling 60-70k PPD again. Thanks for the info! :)
