I just realized I hadn't saved the voltage on that profile! Now, with voltage, we're at 1541 and no more log questions asking if I'm OC'd.

I've been running my machine 24/7 for almost 2 days and I've yet to break 100k. Could the low voltage have been causing errors in the WU, and would that be why my PPD are still drastically lower than reported?

Or, is the base credit the credit received - and estimated credit is the bonus you earn after the initial 10 WU's are completed?

Maybe the best question to ask is, "Is there a guide on the FAHControl client?"

If a WU fails you don't get the bonus points. So unless you produce 10 WU in a row without error you won't get any bonus.
That's my understanding anyway.
Probably @lanofsong knows in detail.

The main reason that work units fail is an unstable overclock, try clocking it down and see if the WU still fail.

Not sure if you checked this guide already.

I'd looked through the guides hoping to find something like a Data Dictionary, and I found This List of Folding Terms. It was definitely helpful, but it didn't have what I was looking for.

QRB - Quick Return Bonus is applied if the passkey has a min of 10 good WUs and an average of 80% after that. Until then you'll get the base points. This is per passkey so you can quickly get to 10 WUs by running the client on your CPU as they run much faster. 1 thread needs to be left to feed the GPU so reduce the thread count to an even number. IE 6 threads on a 3770k.

I hadn't considered using the CPU slot to speed up the 10 count, thanks for mentioning it.

Are the QRB the estimated credit, and non-QRB is the base credit?

Base Credit + QRB = Final credit given. With modern GPUs most of the credit will be from QRB. The client just gives a rough estimated credit as that is determined by the time at which the server receives the WU. The 1st several % of the estimated credit can be really far off. It can grossly overestimate as well if a WU is paused and restarted as it calculates TPF based off the partial % completed as if it was the full %.

I feel like I'm chasing my tail sometimes (edit: I don't always word my questions well, this wasn't a shot at you for helping thumb.gif) Let me try to ask this a different way?


In the image, I circled the field that I want to know more about. Is this field the estimated QRB points, or something different?

What mmonnin said
What you have circled is the Actual points (base credit + QRB) you will get when you return the WU. Note, if you have slow upload speed this will lower that amount you will get.

How slow is slow? Is a 5 mbps upload going to impact my score?
