70% hashrate drop per what second?

As I understand it, yes - but thats not really important.
Its 70% of the Number in MHz. And that one translates (counting in luck and errors) estimated 1:1 into MH/s.
So due to the hash rate counted in MH/s it is estimated 70% of that. If you would count it in MH/h it still would be relative to your calculation/numbering in MH/h.

The only term I do not really understand in regards of calculation is "submitted hash rate". Is it the number of total nonces translated to MH/s ?

I think the whole -oh ratio variable is hard to grasp... could it be "how many frequency jumps per second" or something we can understand professor?

0.7 equals 70% hashrate drop. 0.6 60% and so far. Base frequency seems to be 200 MHz.

The third fpga on his quad is failing. All the others behave normal

I asked you to return the board a feew weeks ago.

So please don't complain about a non working board without giving me the chance to repair / replace it.

I never complained about the bad FPGA. Things like that happen and I can live with that. That was and is our agreement.

Just tried to give the other guy some advice. If a FPGA shuts down all the time -oh is the only way to find out where the problem is imo. Because if you don't set it, it shuts down after 3 to 4 drops. That can be too early for a bad set heatsink.

@ztex: I dont think he "complains" but only tries to point out for understanding

although I estimate him having bad luck on country borders without knowing about his place - cant imagine other reason to run it that way all the time.

/*! break !*/

Another question due to possible failing on long (ok, here it was <24h with -oh 0.08) running the boards:
Is it possible to exit BTCMiner on errors and read some error-number or parse the logs for dealing with the problem?
Until now BTCMiner wont exit but trying to keep running (waiting for input q or s) and throwing error msg .. so I had to rerun manually

I will add another log in the evening where such a problem with bad string stopped BTCMiner of working - could be due to the pool (but neither of the two backup pools was used) or my internet connection (error message does not say so) .. or perhaps my failing core is into that .. (will first check reconnect time of the router and get the log). But perhaps you have already some idea ...
One simple solution coming to my mind, though not sure it is sufficient: running the startup-script $0 again after exiting BTCMiner (until now I stop it doing that until user agrees with some key using read -s)

Or simpler: How to run clusters automatically (e.g. headless without monitoring) and handling errors best?
Or: How to monitor another way than checking the logs?

Turbor, what you see in your first log is called the "downclock of death" and people, including me, have seen this for a long time. What you see in your second log is just normal behavior.

What do you mean by normal behavior?

Oh, I thought that the last two lines (212 MHz and 208 MHz) mean that everything is fine and dandy again.
I didn't see the "FPGA is shut down to prevent damage" line.
If it's shut down, why does it then have normal frequencies like 212 MHz, 216 MHz and 208 MHz again?

Anyway, this sounds like a classical RMA situation to me.

Yeah i know about DCOD. What do you mean by normal behavior ? This DCOD will lead to a disabled FPGA. If you set -oh to 0.05 it will disable the chip at 188 MHz and with -oh 0.7 at 60 MHz. Funny thing is that from time to time I'm able to mine at 120 MHz until I restart the board.

The FPGA downclocks immediately because it does not deliver correct results anymore (Its from April batch). The only thing you can try to fix by yourself is to clean the FPGA if you used thermal grease with metal particles (not the one delivered with the cooler). This stuff sometimes disturbs the communication between FPGA and USB controller is it is below the BGA.

If this does not help it hat to be returned for a check.

OK, I will try that on Friday - right now I am not close enough to my little rig. Lets hope it is that easy

Set -oh to another value. Try 0.1. This way you can see how low it will fall.

If it is an overheating issue you can use this setting to see how low it fails before the FPGA is killed ...

Killed in what way ?

Mine used to fail from time to time. Since i did -oh to 0.2 everything is hashing good

I remember ztex telling better not changing -oh >0.1 and the prog says the same, so to prevent further damage I stick to that until he says sth. else.
Also the hash rate drop here occures right after start - very fast, no real runtime at 200 MHz.

Just some logging now:

As you see *11 is ok, *AA problematic.
Also just one of the other cores seems to react, but not everytime the same, here its #4, but also I saw #3 and #1 clocking down before.

Mine used to fail from time to time. Since i did -oh to 0.2 everything is hashing good

Set -oh to another value. Try 0.1. This way you can see how low it will fall. I have one chip on my quad that only works from time to time. If I set it to 0.7 the overheat protection takes the chip down at 60 MHz = 70% hashrate drop.

Thank you for the backing -so I'm not alone ^^ .
The help says better not to set >0.1 - so I wont try that for now.

Now two boards on Ubuntu, but still the one FPGA #2 fails, #3 of the same board is down to 200 MHz (16 less than before). Others run the same stepping as before.
Hope next Friday evening is brighter than today ...

There is nothing else you can do. You can set it to 0.08 or 0.09 if you are afraid. You cannot damage the chip if the heatsink is well placed. It will just clock down.

@ztex:
after trying to get one quad-board (labeled 1.15x) running on Linux (Ubuntu 12.04) I have growing problems with one of the FPGAs
that chip already was the slowest in my setup leveling in to 208 MHz (all others do at least 216 Mhz) previously on Windows 7 .
after realizing to utilize sudo also the linux-client ran right off, but it shut down the FPGA #2 due to increasing errors (4-10%). That I already had with -oh 0 on Windows 7, but with -oh 0.04 it was OK on 208 MHz.
Now reconnecting to Windows for double-checking the error also occurred there, #2 is disconnected due to error rate.
I already remounted the cooler two times, covering of the chip with MX4 looked ok, nothing besides the chip.

Any ideas what to check/try next Huh
