GPU PPD KNOWLEDGE BASE
I'm not getting the same F@H PPD for my GPU as shown in the database, how do I fix it?
There are several reasons that you might not be seeing the same points per day (PPD) score for your GPU vs its equivalent in the database, others GPUs of the same model or F@H web client.
Being new to Folding@Home and running without an API Bonus Passkey
If you are running Folding@Home for the first time or after a fresh re-install you will need to ensure that your F@H client has been setup correctly with your username and API key.
If you run without an API key your PPD will be significantly lower than those in the database for the same GPU as you will not be getting the API key return bonus that is reflected in all PPD values in the database.
Pausing or stopping the folding client mid work unit
PPD (Points per Day) is based on an average of different work units, research projects etc. as folded on a specific GPU type.
Your PPD values will therefore fluctuate based on situations where you slow down or stop the folding process which does not allow your GPU to fold 24/7 at its best possible output rate of PPD.
For example, if you are in the middle of a work unit and you pause folding to play a game you will notice the PPD will start to drop as time passes because you are using the GPU for something other than folding.
If you leave the work unit paused long enough you will see the work units PPD drop to the point of just the base work unit rewards points as high PPD is rewarded as a bonus for completing work units quickly.
You will also see work unit PPD fluctuate as you use your computer as most operating systems, web browsers etc. are 3D accelerated using GPU resources meaning while folding you can slow down your GPU and lower your PPD slightly doing simple things like browsing a web page with animated GIFs or watching streaming video.
Your GPUs model, firmware, manufacturer, thermal design, and related settings
Not all GPUs of the same model and GPU chip type are made equal, cooled equally or have the same settings in each individual folders computer because of this your GPU model may get much higher, the same or lower PPD compared to the database overall average for you card as if the majority of folding samples come from enthusiasts (which are commonly using the database) they often overclock, under volt tweak fan curves on some the best GPU variants of a model available to get the most PPD.
Research project work units give different PPD returns and change over time
Because each work unit for a research project often contains different data to be folded the PPD rewards will vary between work units and projects such as Covid, Cancer etc.
Therefore, the database lists PPD values in overall averages for a GPU which accounts for all work units and projects blended because everyone is going to see different work each day making their PPD results a little different.
This is why you should not be discouraged if you fire you your GPU to fold and get a Cancer work unit that has very low PPD compared to the blended average as you likely just have a difficult work unit or project… then 2 work units later you may be issued a Covid work unit that will provide far more PPD than the cancer one in a shorter amount of time which when averaged gets you to the average PPD reported in the database in most cases.
