Sick. Thank you. I will try that.
Do you happen to have some efficiency numbers from your system??
-Optim
I have 1 pdu running a dps-1600 with your board and with a evga 1600 p2.
I get readings of 10 and 11 amps for two s-9s
So 2400 watts to 2600 watts for 24 to 26 th.
I have a second pdu so if I run 1 s-9 the pdu meter will be 5.0 to 5.5 amps as my pdu has only 2 digits.
I will be able to do this on Friday or Monday
That's not quite as accurate as I was hoping. Are you able to measure the voltage at the supply output and at the end of the PCI-e cables? That is the real number I am looking for tbh, though running a power analyzer as described above is the best system level information.
I am only measuring with DC load at the moment and I find it is much less reliable.
-Optim
i can give 5 numbers
ac amps at the pdu and with only one s-9 it will be 4.8 to 5.3 amps
ac volts at the pdu it will be about 239 to 241
dc volts at your board with full draw
dc volts at your board on an unused jack
dc volts at the s-9 end
Awesome. Those will work. Would it also be possible to monitor the PSU output voltage under load? The easiest place to check is on the large connector on the breakout board.
I just talked to my contract manufacturer. He was able to salvage a single 4k board right now. I should get it in my hands next week and run some tests. I don't suppose you want to try this one out in the coming weeks?
-Optim
yes I would like to as i can test it against the other 4k board I have.
I am still waiting on the ups truck but should get the batch 4 s-9 sometime today.
gear is here and it is mining at ck.solo pool
if you look the freq is at 525 the fans are also set low 50% why did I do this .. I am testing in my house which means my wife will kill me if I set fans to 90% and try to see if I can go to 625 over clock.
I did run at freq 600 and was close to 12,800gh
As you see the down clock makes 0 errors
and fans set at 50% are okay not nasty bearable
more to come. on volts etc.
pdu reads 5.1 amps
same pdu
2 car garage is filled with new gear for my kitchen remodel pdu is under the british shoe box
spinning to my left i face the back door and the s-9 is vent out the back door and is hidden by a moving blanket. the sound is okay in my den next to the garage.
