Topic: Unofficial Spondoolies SP20 thread - page 34. (Read 126168 times)
I am wondering if it would be possible to run an SP-20 with a single CX-750 with lowered voltage settings any thoughts what the settings would be or if it's feasible?
Is it possible to change to PSU efficiency in the formula that calculates "wall watts" ?
I know the preset one is 0.90, but mine are 0.93
If I can update that number in the firmware, I'd have more correct readouts.

0.93 is based on the official test of one unit, but of course can vary a little in reality and with PSU age.
Do an interesting experiment: Using a KillaWatt meter test the actual draw. Compare that to SP20 software reported value.
If we know the reference preset is .9 it would mean I would hope your KillaWatt draw would be less than the number advertised.
I did all that for my PSUs, that's how I came up with the 0.93 value.
Now all I need is to be able to update it in the the firmware, so its' calculations are correct.
right now it is very close to (board1+board2+board3+board4)X1.1
just do the same and multiply by 1.07 instead of 1.1, unless it is a vanity thing (records of smallest watts, etc, but since it depends on PSU it does not matter anyway)

I do these tests constantly and depending on the PSU and(!) the actual percentage of it's maximum power draw it is very close to it.
depending on the PSU the efficiency can drop a lot if utilized under 25%.
e.g. with a 2000W PSU it's always smarter to run 2 SP20 (up to 1600 GH)

Looks to be the mapping for the basic settings page vs. the advanced, as fasr as I can tell not a new feature...
silly me.did not notice that button.

noticed that on a slow computer. is it hidden as upcoming feature?

I'm going to order the 3 x SP20 bundle for $1200. One question is how do you set one up to run at 1.6 TH? I have cheap electricity, no worries there. I would like step-by-step guide, please no link to Dogie's guide for noobs, his guides are a waste my time.
It seems I have to fiddle with voltage and watts and what not, very confusing. How do you set it up for 1.6 TH each unit? I have a bunch of 750 W Corsair modular PSUs. TIA.

Thanks for the comprehensive information! That's what I was looking for!
Dogie can learn a thing or two from Phillipma.
Thanks, buddy - raised a request.
So it looks like I have a problem with one of my units - the fan stays on 80 no matter what I select in the UI. I've factory reset it a few times, tried on different firmware versions but no matter what I change the fan speed to it doesn't actually change the fan speed. I even looked and the mg_custom_mode file via SSH and it reports the same value as what's in the UI.
Not sure if it's the fan itself ?
I don't really want to open the other units and take a fan from another to test this

Someone else had the same problem, its probably a wiring issue or a problem with the fan itself.
Open a ticket with support and they should be able to send you a new fan

Out of the box it should run close to that, it's self explanatory when you get in the web interface..

what does BIST stand for?
tia
BTW I added 1 more sp20
I now have 9 and 1 s-5.

Gotta say Im impressed w/ the latest 2.6.9 firmware. I noticed a new stat on the stats page "wall watts" ... its pretty damn close to what my killawatt measures, how the hell does the the SP20 know what the PSU is drawing from the wall? LOL that kinda baffles me....
The voltage scheduling is neat.
For future releases, I would like to see improvement in wifi compatibility, my wifi dongle which is listed as supported chipset is not detected by the SP20 =(
Also whats the 8 mean for alt-bistword? What exactly changes in BIST when using that 8?
Also, curious is there a way or will there be a way to to hand tune running parameters, such as clocks ? So I can try to squeeze every bit of extra clock at a given voltage ...

I also thought that it measures it at the wall, but it is actually just a guess assuming 90% PSU effectiveness, hence I got a difference between an actual at the wall and what SP20 shows when i use bronze power supply like CX750M, but close to actual when I use Gold EVGA 1300.
Ah, well guess my PSU's are pretty damn effecient LOL ... dang I was hoping it was some sorta magic ahahah!
