Thanks suchmoon for the response. A=3908096/T=361680=10.8. Yup. Right on the money; 10.8mhs exactly what cgminer is reporting. What does anyone suggest to do next? Give it more time?
Not sure now, I was kind of expecting it to be closer to CM numbers :-)
Can you check if you mined at CM all the time, no backup pools involved?
What does your 24-hour hashrate chart show?
Good points. I've been on the CM pool for the full 10hr.28min duration (no pool switches) and there was no downtime I could see (summary polled every 5 seconds). The 24hr CM hash chart just came to life and it says I peaked out at 9.07 (which is close enough) during the 1st hour. The 2nd-5th hours dropped and peeked out at 7.6, and the final 3 hours are in the 5.1-5.8 range. The 9th-10th hours are not on the chart yet. In my cgminer log, I've been a constant 10.8 throughout the 10.5 hour range. I think it needs more time?
Let's go back to that formula. How did you get the T=361680? It doesn't add up to 10.5 hours for me. It should be ~37800 and with that I get
A * 65536 T = 3908096 * 65536 37800 = 6775687 = ~6.8 MH/s
How is temperature around blades? Power supplies ok? Any USB errors in system logs?
Regarding T=361680. You're so right. 10hrs * 3600 = 360000 (oops should be 36000) + 28 mins * 60 = 1680. Total 37680 seconds. Geez the original 361680 gave me the magic number I was looking for that I did not even double check the math. How coincidental is that? Furthermore, I did not even multiply A * 65536. What a brain fart on my part. With the given correct number of seconds and using your formula A * 65536 T, the new number is 3908096*65536/37680=6797265.909 or 6.8mhs. You've got it. Is that suppose to be an average of something? Or is that how CM computes mhs at any given time?
My 2 blades run cool at the touch even around the voltage regulators. I've got it clocked conservatively at 800mhz. No usb errors ever in the system logs since I got them a little over a week ago. And the first (and last) week on weminerltc, they ran at a steady 10-10.5mhs on their charts.
The 9th and 10th hour just came in at 5.41 and 5.24. And the Last Hour Hashrate right now is 5.2mhs. cgminer is still rocking at 10.8mhs. I'm not sure what's going on. Could you explain your formula a bit more? Thanks much for the input.
Edit: I think I know what's going on. Since the formula for the hash rate is based on accepted shares, all 4 of my blade boards had the proper hash rate, BUT 2 of them did not have the proper wu rates which led to improper accepted rates. ahha. I decided to reset the system and give it another whirl. So far so good. All 4 boards are logging expected numbers. Hopefully, the numbers will reconcile with CM's hash rate. Thanks again for the road map and interesting conversation.
