"All clients getting their SP20s:
- Please set your PSU settings to match your PSU. The default value is low and will not give you beyond 1.3Th - it matches weak PSUs. Set it to 288 if you have strong PSU.
- SP20 are very sensitive to temperature. You should be able to get 1.8+Th in 10c, 1.7+Th in 20c and 1.6+Th in 30c (+- 5%). Do your best to cool the units."
My results are completely the opposite of the above statements from Spondoolies website... -dual weak (750-700w range) PSU's appear to be way more stable than anything large and efficient. So far my best results have come from a pair of bronze rated PSU's over any combination of large platinum rated PSU's. -I have yet to reach 1.8 and have run the machine in temps from 0c to 25c, right now its in a 5c climate and cranked up to 288 running 1.6-1.625....
I have emailed Spondoolies but have not recieved a response....cheers...keith
288w is the limit on the PCIx power connectors. There are ways to override it in FW with flags, but don't do that (at least now). We remember what happened to other ASIC mining company equipment when they pulled ~400W on those connectors. got it.. i'm not tryin to burn my garage down even though it is detached. Well there has to be another to get better performance out of the sp20 at lower temps let me know what you guys find because I have two more on order in the next batch. no there is not. four plugs = 288 x 4 or about 1152 watts which means use the egva 1300 g2 and use the cables with double headed plugs. just use the first plug . I will place a photo. this is a design flaw in a sense if you are an oc freak. for me I am fine with it since I don't want to oc the gear. I will use the 250 setting. with my evga 1600 p2 and let the coins roll in. double plug connection on the prisma. so my prisma was easy to send lots of power with no fear of hot cables. it just had other issues so I sent it to a DC ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fimagizer.imageshack.us%2Fv2%2F1280x1024q90%2F540%2FWDiMKB.jpg&t=665&c=Az4CmAB_EcKnqA) this is the cable from an evga 1600 p2 note the first plug (8 pin) has thicker wires then the extended plug it will handle close to 300 watts ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fimagizer.imageshack.us%2Fv2%2F1280x1024q90%2F537%2Fzh6ca2.jpg&t=665&c=bMnA09lNT6m9YA)

So you are saying four connectors pulling 300watts per for the sp20 is the the issue ?
I don't see how that could be the issue I think its either an issue with the firmware or the Asics themselves.
If a sp31 does 4.8 - 5 TH using the same chips at 2800 watts.
A sp20 should be able to do at least 1.8 TH using 1200 watts of power unless something is seriously goofed, since it is the same silicon basically.
If you are right and it is an issue of Maybe it is an issue of the SP20 needing to be able to pull a bit more juice say 330watts vs 300 thats a different issue I guess.
Either way 1650 TH is not good for 1200 Watts and that is what the majority of folks are seeing. I'm leaning to maybe canceling my order if this is something set in stone.

Yes I think they did a design flaw since most current/watts sent on 4 connectors = 4 x 288 or 1152 watts. that is the max rating. so when you try to send 1200 watts over a 1152 rated connection you waste power. I In my case I do not care about this issue since I plan to use 250 setting not the 288 setting. but any one wanting to send 288 or more is just wasting money. I would love to see clear testing from some one that used an evga 1300 or an evga 1600 set at watts of 225 to 250. I am pretty sure those will be the best watt to gh settings. I am going to have a lot of fun with this gear in the underclock undervolt world should be fun for me. but if you are an oc dude/dudette this may be bad gear.

The rate, assuming all ASICs are operational, depends on the ASIC batch. First batch of SP20 gave us ~1.8Th in cold temperature, but a lot of the units I see now are slower and provide something like 1.65Th. The ASICs behave as if they are from slow batch, I need to investigate why. The SP20 we produce now are faster - it looks (from the system tests in Flex) like they will provide 1.8+. We will have exact numbers soon.

give me a few days for my sp20 to come. I had the prisma and it was the loudest miner so far. although the short tube was very close to just as loud. once I get the sp20 I can compare

Hi Guys,
We have a heap of SP30 miners, all working pretty great thanks.
Tonight one miner shows an error on the ASIC page
disabled (Asic all engines fail BIST)
I have restarted miner gate, this doesn't make any difference I have disabled and enabled in the Settings > ASICS Control Panel, this also makes no difference I have rebooted the miner at the mains, this again makes no difference.
Yesterday I upgraded all miners to version 2.5.12.
The settings on this miner are as follows Fan Speed 80 Start Volts Top 0.64 Start Volts Bottom 0.64 Max Volts 0.79 Max PSU Top 1360 Max PSU Bottom 1360
Temp Front / Back T,B 16c / 52,53c Socket Voltage 222/221 volt
Any assistance would be gratefully received. Thanks Guys

give me a few days for my sp20 to come. I had the prisma and it was the loudest miner so far. although the short tube was very close to just as loud. once I get the sp20 I can compare I have both Prisma and SP20. I don't have a db meter, so I unfortunately can't test that way. Stock, they're both pretty loud, too loud for your living space IMHO. I have yet to try tuning the sound down on either, though a few posts back someone changed fans on the SP20 ... https://bitcointalk.org/index.php?topic=521520.msg9546908#msg9546908As well, on dogie's guide for the ASICMiner tube, someone replaced the stock fan to make it quieter. https://bitcointalk.org/index.php?topic=769570.msg9561108#msg9561108Hope that helps a bit ... ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

It does not help at SP20. Neptune plug connector is air-cooled by 14 cm fan. SP20 design is different. Hi i am not sure you guys know this but it has been helping many of the KNC mining guys, it is a 16awg wire Y psu cable, so two 8pin go in to the psu and go to one 6pin for the miner then the amps will be higher and the power more stable i also have a 6pin splitter that you can use with the original cables ps. i was here getting info about the sp20 miner thinking about buying one ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) not in a sales campaign Corsair have specially needed the Y cable but now days i am asked for most all psu´s

I will also post my evga g2 1300 and my evga p2 1600 when I get the sp20 My opinion is this 250 watts should be your max setting and underclocking should be what you want to do. Basically due to the 4 jack setup since the jacks rate at 288/300 watts and you want a margin of safety so 250 should be ideal. maybe 225 or 240 but I do not know if 225 or 240 can be set. This is strictly based on the rating for those jacks and for evga 1300/1600 wires . I will be happy with 1000 watts and 1400 hash

mine is still listed unfulfilled where did you get the 26th? never mind found it http://www.spondoolies-tech.com/products/sp20-jackson-november-batch-2so do we get 8 days of hash at 1.7th paid to us? that comes to a 0.16976 coin refund. I guess we have to wait to find out.
