I've only got one bad one since around 2PM yesterday on both GPU's.  Apparently on FF the faulty rate is much higher than normal and only the first two I did received bonus points the rest are just giving base at the moment.  I'd remove the beta tag or switch to advanced in the meantime while they fix these.

You could try testing an idea I had but didn't think was necessary when I found out about the fixes- while the slot(s) are paused, replace the copy of core 17 in the non-beta folder with a copy of the beta version.  I'm not sure if WUs assigned via a non-beta flag will just use any copy of the core found in the non-beta core folders; there may be some code in the core itself that indicates it's a beta version.

Sorry dude maybe next time. I got frustrated and deleted them, beta and all, and reverted to older drivers. GK104's are folding happy again.

I've swapped to advanced flag (only change made) and picked up p13000 and p13001 giving around 75k ppd per slot (3 x ref 670s).
Just checked of the 780 classy and found same problem there so switching flags on that rig too.
Sorry Central, let my eye off the ball for a second. Game face ON!

That is the only project I am getting now for over 24 Hours.
It is quick less than 2 to 3 hours

But I do only see 12000 or 8000 credits per card.

5,920 Credits now on a GTX 780 and now seeing more Max Retries Reached and BAD_WORK_UNIT and so far I have not received any QRB

As far as I can tell you are getting your QRB since the fix;

Your WU (P9201 R431 C0 G0) was added to the stats database on 2014-04-24 15:02:53 for 17104 points of credit.
Your WU (P9201 R81 C1 G0) was added to the stats database on 2014-04-24 16:02:49 for 16624 points of credit.
Your WU (P9201 R219 C0 G0) was added to the stats database on 2014-04-24 17:02:50 for 14232 points of credit.

Hmm I restarted on the P9201s since the "fix" but I'm still not getting a qrb.
Can you please verify if there is anything required our end, such as updating core files in order to get the qrb running again?

 Sometime I works and other time QRB is not working, but it is Beta.
 37,140 then 8,000 then 32,072
 
 

I would go back to client-type = advanced and the both pulled P9101(Version 0.0.52) MUCH Better then P9102 Beta on NVIDIA and AMD GPU's
(On New Cards that is). Then after the TZC users can go back to Beta (Testing) I know this is no help for Non GK110 GPUs.
