why i said to raise it, is because the fan is really obstructed the way you have it now.
the difference in temp from floor to 10inches above floor is almost none, but a good airflow is best!
I will attempt to raise it later you may be correct about the fan blockage.
The tape seems to be helping.
this is a new number with window closed. very good hashrate but early.
Philip,
Have you found that on your test miners that there are Frequencies that work at higher points rather than lower? Example - I have most of my miners at 392.75 - some at 400. Some got x's at 400. Is there reason to think maybe that a miner that x's out at 400 - might actually work at 412?
Cheers,
Strato
The two I had both can do freq 412. but cold rooms and lots of fans are important.
As for good freq vs shit freq. I have found that 275 was not good and 318.75 was bad.
The key for overclock is look at the HW as long as they are under 0.05 good rates show up. for me 412 is very good 425 errors got high 0.088 and has was lower at 425 then 412.
You need to wait at least two hours to see:
the rates settle
the errors settle
the temps settle
when you get over 375 freq .
Also the pool you are using can affect hw's.
I built a 1 dollar 4 sided should using a cardboard box and duct tape . not sureif it helps will continue to test.
