sta2009 Должен тебя огорчить, "ошибки" в расчётах на GT8400-8600 так и не исправили.
Доктора забили болт на нас владельцев таких карт.
Сам собрал конфиг по совместительству: 8400GS-8500GT-8600GT. И получил чупа-чупс.

Так запускается же на 8400GS и 8600GT. Надо на ней ферми форсировать.

2) Использовать ключ -forcegpu доктора настоятельно не рекомендуют - ибо это может сказаться на их научных изысканиях. В данном случае - использовать ключ -forcegpu nvidia_fermi на не-Ферми видеокартах - из разряда "вредных советов".

The GPU3 BETA Client identifies the GPU type and reports it in the FAHlog like this "Gpu type=X species=Y." Below is the list of what your FAHlog would show depending on the GPU Type and the Driver installed:

Gpu type=1 species=1. -> "Gpu type=1" indicates an ATI GPU; "species=1" means ATI_R520.

Gpu type=1 species=2. -> "Gpu type=1" indicates an ATI GPU; "species=2" means ATI_R600.

Gpu type=1 species=3. -> "Gpu type=1" indicates an ATI GPU; "species=3" means ATI_R700.

Gpu type=1 species=4. -> "Gpu type=1" indicates an ATI GPU; "species=4" means ATI_R800.


The GPU3 BETA Client identifies the GPU type and reports it in the FAHlog like this "Gpu type=X species=Y." For Nvidia GPUs, the "species=Y" is based on the compute capability of the installed GPU. Below is the list of what your FAHlog would show depending on the GPU Type and the Driver installed:

Gpu type=2 species=22. -> "Gpu type=2" indicates a Nvidia Non-Fermi GPU; "species=22" means CUDA 2.2 is available.

Gpu type=2 species=23. -> "Gpu type=2" indicates a Nvidia Non-Fermi GPU; "species=23" means CUDA 2.3 is available.

Gpu type=2 species=30. -> "Gpu type=2" indicates a Nvidia Non-Fermi GPU; "species=30" means CUDA 3.0 is available.

Gpu type=3 species=0. -> "Gpu type=3" indicates a Nvidia Fermi GPU; "species=0" means CUDA 2.1 or earlier. It can also mean that no CUDA runtime file found.

Gpu type=3 species=22. -> "Gpu type=3" indicates a Nvidia Fermi GPU; "species=22" means CUDA 2.2 is available.

Gpu type=3 species=23. -> "Gpu type=3" indicates a Nvidia Fermi GPU; "species=23" means CUDA 2.3 is available.

Gpu type=3 species=30. -> "Gpu type=3" indicates a Nvidia Fermi GPU; "species=30" means CUDA 3.0 is available.


Under some conditions, your GPU will not be recognized so it will display this message "Gpu species not recognized." The common reasons are:

1) You haven't installed the correct Driver. Check what Driver is recommended for Folding or try the latest ones by your GPU Vendor.

2) You may have stubborn files from the previous driver that is causing this error. Please use Driver Sweeper and try again.

3) You might be using a recently launched GPU Model that isn't recognized by the GPU3 BETA Client. If this happens, by using this method, an appropriate flag may be added which would allow your GPU to fold. The flag will only work if the GPU architecture is similar to the previous one. It is advised to search the Forum for the GPU in question to see which flag is required for it to work:

-forcegpu ati_r600 -> It bypasses the Clients' auto detect feature and instructs it to treat the GPU as a 3000 Series one

-forcegpu ati_r700 -> It bypasses the Clients' auto detect feature and instructs it to treat the GPU as a 4000 Series one

-forcegpu ati_r800 -> It bypasses the Clients' auto detect feature and instructs it to treat the GPU as a 5000 Series one

-forcegpu nvidia_fermi -> It bypasses the Clients' auto detect feature and instructs the Client to treat the GPU as a Fermi architecture, i.e. the GPU is a 400 Series one

-forcegpu nvidia_g80 -> It bypasses the Clients' auto detect feature and instructs the Client to treat the GPU as a G80 architecture, i.e. the GPU is a 8/9/200 Series one

4) You may be trying to run the GPU3 BETA Client on the GPU Model that is too old hence isn't supported by F@h.


Note 1: Using the -forcegpu flag with the wrong GPU will mess things up. It may invalidate the scientific results produced. DO NOT MISUSE THESE FLAGS. (Details)

Note 2: Please remember that officially, Overclocking is discouraged. (Details)

Note 3: If you are using 8800 Series GPU or 9800 series GPU, you may encounter bugs. The Development Team is aware of it and are working on a fix: <Click>

Note 4: On some GPUs, when it is folding, a high pitched whine noise is emitted from the GPU. This is called Capacitor Whine and doesn't pose any serious threat to the GPU in use.

Note 5: Please note that the following GPUs MUST NOT USE the -forcegpu nvidia_g80 since they will be assigned FahCore_15 WUs which they cannot process:
Nvidia GeForce 8800 GTS
Nvidia GeForce 8800 GTX
Nvidia GeForce 8800 Ultra

Using A Fermi GPU & A Non-Fermi GPU In One System
When combining a Fermi GPU with a Non-Fermi GPU, the Fermi GPU will fold FahCore_15 WUs while the Non-Fermi GPU will fold FahCore_11 WUs. However, if the Non-Fermi GPU attempts to fold a FahCore_15 WU, it will result in an error if the Clients aren't properly configured. In certain situations, this setup may not work. Nonetheless, you have the following options:

Option 1: Make sure that there are separate folders for each GPU. After that, use these flags with the correct GPU:
Fermi GPU: -forcegpu nvidia_fermi
Non-Fermi GPU: -forcegpu nvidia_g80
You may use one or both flags to see if your GPUs can fold FahCore_15 WUs without any issue.

Option 2: Run one instance of GPU2 Client for the Non-Fermi one and one instance of the GPU3 BETA Client for the Fermi one. IMO, you may want to use the Console Version of both Clients as all the files are included in it and it is a no-nonsense version which makes it easier to set-up and reduces the possibility of errors.

Option 3: Takeout the GT 240 from your current system and place it in another system (contains non-Fermi GPUs only) so that it can fold FahCore_11 WUs and FahCore_15 WUs without any issue.

Thanks for asking about this. Here's the situation. Using -forcegpu like this really screws up a lot of what we do. In particular, it can both invalidate the science from others (by throwing in some strange results) and make it really hard to track down bugs since we can't tell which GPU is which. This also slows down other progress (more wild goose chases).
If this flag gets abused (i.e. used to mislead the AS to increase points), we'll have no choice but to remove it. This would be a shame since it would simply make it harder for those using the flag legitimately, but we'll have to balance the pros and cons as always.
From the posts above, it's clear that people are not trying to be malicious and just wanted to know if it was ok. Thanks for asking.
