"Result" field for a Cert needs something more informative than n/a in all cases; match or mismatch, pass or fail, something. Maybe also proof power in case of a success.

Hi, that is the first tested exponent from a recently assembled computer (the GPU is a Fury X from a previous machine).

No significant changes have been made (I believe):
  1. gpuowl path to openCL was modified (Makefile)
  2. rocm-smi --setsclk 2
  3. config.txt: -proof 9 -nospin

Do you have a gpuowl.log file that we can look at for error messages?

We'll see how long my free GPU lasts for this and how far into a (7GhzDay) P-1 that gets me.

I have been testing my Ryzen 3 3200G computer with both mfakto and gpuowl. I posted my mfakto results in the mfakto thread. The last few days I have been testing gpuowl with some interesting results. I think I computed all of the GHz-day/day correctly.

Code:
Computer - Asrock DeskMini A300, AMD Ryzen 3 3200G, 16GB RAM, 256GB SSD 
Programs - Windows 10, Prime95 30.3 Build 4, GPUOWL v6.11-364

I did a major hardware upgrade today which i wrote about in my blog. I was hoping for some significant improvement in P-1 run times. That didn't happen. The Stage 1 time was shorter, but Stage 2 was longer. Basically, no gain. I haven't tried a DC or PRP yet. I have a feeling they would not do any better either. I shifted my P-1 work to Prime95.

I want to use this where it would do the most good. Since it sails with mfaktc-2047, I am considering TF's to a bit level where they would be P-1 ready. 76 or 77 bits. By no means am I disappointed. Just not the result I was hoping for.

Getting over 5 hours a day last few days.
P100 is doing about 14GhzDays per hour..
T4 is about 5 times SLOWER.
Haven't gotten a K80 or P4 yet.
