WARNING Do not upgrade to 375/376.xx drivers (for xx<48)

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

Personally, once I find a driver version that's dependable, I don't upgrade spontaneously and I never choose a "game ready" update since they don't provide anything interesting to me.

Thanks! That sounds like a plan. I don't intend to update again for a very long, long time.

If you do not have a specific reason to upgrade and your folding is working I recommend not upgrading at this time, at least until there's some assurance that nv has released a valid update. If you already did and folding is not working please reinstall the older drivers that worked.


@Adam A. Wanderer: Many thanks for reporting this issue and increasing awareness of it. :)

While I agree with bollix47 that unless there's a specific reason to upgrade, don't. But for me the main reason I upgrade drivers is not to benefit from the performance improvements to games (I generally don't play the latest games) but for security fixes. The 375 drivers fix multiple security vulnerabilities for Linux and Windows

While they aren't remotely exploitable, they allow an already present attacker to further compromise your system (local elevation of privilege). There have already been multiple security updates this year. A full list is available here.

I will be closely monitoring both forums and will update the drivers as soon as possible when the Core 21 issue is resolved. Thanks for working towards resolving these new driver compatibility issues.

Just installed Nvidia driver 375.70 and it is returning bad work unit errors. Will return to previous driver This is the second version of the 375.xx driver that I have tried with the same bad result.

Security problems and potential vulnerability drivers are relevant for those who, for some reason, launches a lot of untrusted downloaded from the network code on their machine.
If so, then updates are needed.

But this is specific type of activities.

Agreed but I am merely installing these security updates to provide defense in depth for my system and as a best practice to maintain it's security (the same reason why people install operating system updates). I don't run un-trusted code on my machine.

Same, folding on CPU only is killing my PPD :(

You could uninstall the driver, reboot, and the install the last known compatible driver.
That would be the only fix as of now.

I do not believe that patching FAHCore_21 is a realistic option. FAHCore_21 brings additional scientific capabilities to FAH which are not in earlier cores. To do that, it apparently it uses some additional features in OpenCL which were not used by Core_18. NVidia's drivers supposedly provide an API which contains a full range of OpenCL calls, and if something is broken, it's a problem for NVidia to solve. It's a bit like saying that if you can't watch videos which contain a blue color, it's the responsibility of Netflix to avoid displaying anything in blue.

^agreed. If a driver update broke it, the only fix is a new driver.

Not really, it's not like they're going to list a phone number or anything.

Just download the 373 driver.

Return to 373.06
Sorry for the translation. This aspect, obliges me to very short and concrete sentences. Little by little he will go forward, also in this field.
Thank you for your understanding. Jorge Barrientos

A further update from a Nvidia representative within their 375.76 Hotfix driver thread confirms they are still looking into it. It was mentioned in another thread that a new driver is due for release around the middle of this month. We will need to wait and see if it contains any fix for this.

Thanks.

[removed since this was not a valid workaround, just coincidence that it started processing Core 18 as soon as I changed a setting]

Not really a usable workaround for folding. Specifically the 375 version drivers will not work with Core_21 projects which are the majority of available GPU projects at this point. The Core_18 projects that do work with this version of the drivers from nVidia will not be available all of the time.

There are some bad work unit failures, but most appear to be starting and completing successfully. I have a Gigabyte 1070 G1, if that matters.


Since you didn't post the system configuration segment of your log, I have to guess....
... that you only have one GPU. (a pretty safe guess, I suppose)

The purpose of gpu-index is to distinguish between each of your GPUs, and since you only have one, the setting of "-1" will always choose the system default value of "0". You didn't really change anything.
