I have an S1 set up at freq 400 temps running dead on 44.

I have a HW error rate of about 2.86% which I found to be alarming. So I slowed it back down to freq 375 and the error rate basically went away.

Then I got to thinking.

What difference does the HW error rate make? Does that mean I'm actually losing shares in my pool? Because unless you're running solo, that's all you care about. So I did a little test and this is what I came up with:

Freq	GH/s (from miner)	GH/s (from pool)	Wall Watts	W/GH mine	W/GH pool
400	199.53	204.84	444	2.23	2.17
375	191.52	179.88	414	2.16	2.30

What we're looking at here on the first line is the S1 freq then the speed from the miner status then the speed as reported by my pool then the watts the machine is pulling from the wall then watts divided by the speed from the miner status and, finally, watts divided by the speed as reported by my pool.

So my pool thinks I'm running faster than the S1 thinks it's running with a bunch of hardware errors at freq 400.

But when I slow things down to eliminate the HW errors, my pool thinks I'm dogging even though the S1 thinks I'm doing OK.

If anyone has insight to this, I'm interested.

In the mean time I'm taking the 3% HW hit and also a larger share in my pool.

okay you need the setting for 393 and 387 give me a minute

try 387 and 393 any hw under 2% is okay . look for the accepts at 387, 393 , 400 and look for the errors.

pool readings can be all over the place but they may even out after 1 or 2 days.
