09:38:21:WU01:FS01:0x17:ERROR:exception: Max Retries Reached

The "Bad State detected" messages seem to be preceded by a very long frame time … at one point (just after 08:00) I thought it was stuck and was about to dump it, but it picked up again just in time so I let it run. Even the horrible PPD it was returning (only ~70% of typical) was better than zero from a dumped WU!

But then it did it once too often and errored out.

The GPU temperature varied quite widely during the folding- from ~63ºC up to its normal 82-83ºC, not sure if that's useful.

After that I'm a bit confused as various parts of the log interleaved, but it got a p9406 which was immediately rejected:

(It had earlier completed a P9406 (Run 177, Clone 0, Gen 6) without a hitch)

It then got another P9408 (Run 496, Clone 0, Gen 3) which started like the first one (very low PPD) and I'm afraid I'd had enough at that point- I dumped it and removed the advanced flag. It's now, happily so far, crunching a P13000.

My main question- the 780 Ti is from Gigabyte and slightly manufacturer overclocked- is this likely to be the problem?

If it is, can I reduce/remove the overclock (it's in a Linux box) and if so how?

Otherwise I'll have to try to get it swapped for a stock speed one… which would be a pity

It's entirely possible that manufacturer overclocking is responsible for unstability leadig to failed work units, but not necessarily so (I have two EVGA 660SCs and no problems also in a linux box).
As for downclocking though, I'm afraid I haven't the foggiest /:

I've also got a Gigabyte GTX 650 Ti in an essentially identical box (same OS- Linux Mint 16, same drivers- 319.32) but it hasn't yet been given a P9408.

It handles P13000/1 and P9406 without any bother, as this one seems to, but I only built this system yesterday so possible comparisons are limited...

It does seem a bit strange to get a run of Bad WUs unless the card is too fast for its own good. My factory overclocked 780Ti (different manufacturer) seems stable under Linux, but I too have failed to find a clock setting utility for Linux.

It will be interesting to know if any of your problem WUs get completed by others -- especially if the alternative is to get the card changed.

I think I'm going to have to put it back to advanced and see what happens… and also wait for the GTX 650Ti to get a P9408 to see how that card handles it.

So far both seem happy with P13000/1 and P9406 and, while they were around, the 650Ti thrived on P8900 and P9401, but there's not many ZETA projects around at the moment to get much information and the 780Ti hasn't even been running for 36 hours yet!

I can't do anything until Tuesday at least, so I might as well let it try as many projects as it can to see whether it's the card or if I've just been unlucky with WUs.

For what it's worth, project 9408 is exactly the same as 9401. So if you ran 9401 just fine, you shouldn't be having any issues with this one.

Posted: **Fri Apr 18, 2014 7:36 pm**

Yes, I had a feeling it might be… but I've only run 9401's on the other GPU, not this one.

I'll just have to keep my fingers crossed that it was a bad WU. I'll put it back to advanced tomorrow when I can keep an eye on what it downloads.

It would seem to be the card… picked up a p9101 and:

Code: Select all

05:06:38:WU00:FS01:0x17:Completed 25000 out of 2500000 steps (1%)
.
05:24:28:WU00:FS01:0x17:Completed 100000 out of 2500000 steps (4%)
05:24:32:WU00:FS01:0x17:Bad State detected... attempting to resume from last good checkpoint
05:26:22:WU00:FS01:0x17:Completed 75000 out of 2500000 steps (3%)
05:35:12:WU00:FS01:0x17:Completed 100000 out of 2500000 steps (4%)
05:35:16:WU00:FS01:0x17:Bad State detected... attempting to resume from last good checkpoint

So it's back to normal mode and p13000/1 until I get it sorted.

I don't really want to change the card, it's a lot of hassle and unless I go for a stock (ie significantly slower

) one there's no guarantee it'll work, and I don't think I'd have much luck swapping a perfectly good card on a second occasion!

There is another possibility- swallow some principles and install Windows.

If I understand correctly what's on the driver DVD there's a tweaking utility included, and it may only need a very small clock reduction. It'll be a pretty much dedicated folding machine so I won't have to get too familiar with the OS, the biggest problem would likely be the learning curve- the last version of Windows I used was Vista!

edit- seems I can still pick up legal copies of Vista for a lot less than W7/8, that might be a better route.
