Hey!

The last two days i've been getting only x15 cores, that credit only 5757 points. Does anyone know what this is. x15 used to be around 30k with 4 hours of work. Also, I've been folding the whole summer and never got a single x15 only x17. Those granted always over 90k points.
Did something change with the latest nvidia driver?
I had the advanced flag on my  gpu before. Now i changed it to beta, see if that works.

Any other ideas? 5757 is ridiculously low for 5 hours of work imo.
Here's a screenshot:

Thanks in advance!

    Project 8018 is by far the lowest PPD core 15 project; my 780s do 30k on them while the other remaining core 15 projects do 60k.  At one point, long ago, it was actually among the best, but then they recalculated the points on most of the others and for whatever reason never did the same for it.
     
    This isn't a driver issue, it's server issues on Stanford's end that are causing an extreme dearth of core 17/18 projects being sent out to everyone (as well as a lack of bigadv WUs for those of us with such machines).  Without many core 17/18 WUs to send out, the assignment servers fall back to core 15/16 WUs (16 is AMD only, and they're comparatively even worse than core 15).  There's not much you can do other than changing the client-type flag, but from sporadic reports here and elsewhere it doesn't seem like any flag is consistently getting core 17/18.

    I see. Thanks for your reply!
    It would not be a problem to receive x15 cores to be honest since it finishes fast for the 30k points. x17 finishes in 8-9 hours. x15 finishes in 3 so its almost as i would do x17 cores, but seeing the x15 giving me 5757 points is the thing that bothers me. My PC is basically running for 4 hours straight for a 5757 points...

    Yea, core 15's suck because they don't have bonus points for early completion like every other core. Don't know why Stanford did this but well, they did.

    All I can say is this was why I stopped Folding on NVIDIA Cards and now only Fold on AMD Cards.
    I have 2 R9 290X that I got only to Fold on.  F@H will only say that it is a NVIDIA Problem and it ends there.
    I also believe that in part that once F@H fixed the issues with AMD Cards they seemed to have well need I say more.
    Last they now have their Corporate Partners that have priority on what Projects are give out as to why we run out of Core 17 on NVIDIA Cards ONLY and are then stuck with only Core 15 or No Tasks at all.
    Note that the AMD cards do not have this issue as AMD Cards cannot or do not run Core 15 Projects.

    From what I remember they do this on purpose to force everyone to run Core 15 projects because nobody wants to run them.  They'd rather be stubborn for the past year and leave the points where they are than try to change them.

    I have had nothing but core 17 projects on both my 780s (running 24/7) for three months with the "advanced" flag. Two days ago I started getting nothing but core 15s, so my ppd has tanked. This happened earlier this year and you could change the flag to "beta" or completely delete the flag and pick up a core 17 - but at this point there is nothing I can do to stop the core 15s. Hopefully this will be corrected soon.

    If this was really true then the F@H should also force the AMD to not receive Core 17 and if need be no Tasks.
    Fair is Fair!

    An update to you guys.

    Setting the flag to beta actually helped i believe. I'm back to core 17 units. However these only credit 35k not like 90k before, but they also finish a lot faster, around 2.5 hours.
    My PPD is back to 280-300k so I'm really happy! ^^
    Also my card is suddenly running 1345Mhz on the core with 1.152V, with the LN2 bios after i re-installed the drivers and installed the new Precision 16. It's a huge change compared to before. I don't know what but i think something was holding my card back before as well.





    Thanks for all the replies! :)

    It wasn't due to changing the flag.  IThe reason that everyone stopped getting core 17/18 WUs was because they had rolled out new assignment server code that turned out to still have some bugs in it.  They rolled the servers back to the old AS code yesterday while they fix the bugs and do some more testing, and as a result everyone's been getting core 17/18 work like before; I've gotten nothing but 17/18 WUs without any flags like I had been the last several months.  The new code is going to be re-deployed on Monday; we'll see how that goes.

    Zagen30 is the assignment server the same for NVIDIA and AMD GPUs or is their one for each?
    My info link to Core 18 is no longer working, so I am not sure if AMD can run Core 18 projects.

    I don't know if there are separate AS'es for Nvidia and AMD.  Looking back through my logs, it appears my Nvidia cards are always assigned through the AS at 171.67.108.201.  Check your AMD machines' logs to see where they go.  Search for "Connecting to", and make sure you're looking at lines directly preceding "Assigned to work server xxxxxx".  The phrase "Connecting to" also appears when the client downloads and uploads, but those lines have the IP of the work server.  If you compare the IPs to the server status page, work servers should show up there, while I believe none of the assignment servers do.  I know that 171.67.108.201 isn't on there.
     
    I do know that core 18 still has bugs on AMD cards that cause it to run a lot slower than it should, and is therefore being restricted to Nvidia only until that's fixed.  I think during the AS issues this past week some AMD cards were getting core 18 WUs by mistake.

    140.163.4.231 are what I show for Connecting to in the log file.
    Thanks for that info.

    That's a work server, not an assignment server.  There will be a couple of connections in a short time frame that look like this (I added the "#n"s):
     

    17:15:42:WU00:FS00:0x17:Completed 5000000 out of 5000000 steps (100%)
    17:15:42:WU02:FS00:Connecting to 171.67.108.201:80  <-#1

    17:15:43:WU02:FS00:Downloading 4.83MiB

     
    Line #1 is the request to the AS.  #2 is where the client gets returned which WS to use.  #3 and #4 are the client connecting to the work server.  Note that lines #1 and #4 are identical except for the IP, so you can't assume that every "Connecting to..." has an AS IP.

    It appears, then, that both Nvidia and AMD use the same AS.

    Not so sure about this fix of theirs - I was back to getting core 17s all weekend, but then today have picked up two core 15s. 
     
    Very annoying - my CPU is getting higher PPD than my video card!

    Don't look fixed to me. Back to only getting core 15's here as well. Any news on if this older core is going end of life? They said it was getting phased out almost a year ago.

    I'm actually surprised I went nearly all summer (3 months) without getting a single Core 15.  That's about as stable as you can get with the FAH project these days.
