Okay this is very true, but hard to justify for me, Some who have less interest in ROI. I guess.

Could still push them down a bit, I'd buy a bunch

Please explain, WHY are we still using PCIe connectors?

Why not give terminal points, insert wire and secure, Let me run 8awg wire straight in, less wire.

Time we move away from crappy pcie

i have one of my sp20 feeded by 3 psu with 18awg: corsair 550w for 2loops, 2 nonames for the other 2 loops. settings as posted yesterday:

Temp Front / Back T,B    12 °C / 55,54 °C
Fan Speed    70
Start Voltage    0.67 / 0.67 / 0.67 / 0.67
Max Voltage    0.72
Max Watts    220 / 220 / 220 / 220
Mining Rate: 1439.78Ghs

is true that ambient is pretty low, like 5-10C. cable might be warm a bit, can't really say for sure

got an dps2000bb with special board and 16awg cables. full load ~300w and cables still at room temp!

poor quality 16awg can handle around 250-270W. high quality 16awg can handle about 300-320W. (18awg is only good for about 150W). having a bit of airdlow over your wires allows them to carry 20-30W more before getting as warm

Corsair RM 1000 spec => All PCIe connectors, on the other hand, use 16AWG

Room temp is like 24-26 degrees but the miner are next to a window and it's like -15 outside

what awg and room themp?
thx

The SP20 Nanofarm is 4.8TH/s and $1195, while the SP35 is 5.5TH/s and $2235. So while it is almost double the price, keep in mind you get two 1600W server power supplies with it. I'm guessing SP doesn't get to buy their supplies as used pulls off eBay, so that's probably ~$500 in extra cost right there that they can offload to the consumer with the SP20. If you've already got PSUs or have the time to deal with adapting cheap server PSUs that's one thing, but even if you're going with a nanofarm and ATX PSUs you're looking at $500 worth of power supplies to get the SP20s up and running, plus the extra space of having three SP20s and three PSUs to power them. You're also getting 30 ASICs vs 24 in the
The SP35 should probably come down a bit in price, but I'd say at ~$2k it'd be easily be superior to the SP20 for anyone who doesn't have PSUs sitting around.

I don't think you can really push them over 300 WATT per PCI-E. Spec say 288 max.

Mines are running at 250W, cable just a bit warn...

Maximum power output – each SP20 requires 1152 W RMS continuous power. Spoondoolies-Tech recommends adding a 20% margin to handle power peaks

For the SP20, don't get PCIe connectors start to melt when you are running them? Arent they pulling 300W each?

Wasn't this a huge issue with the KNCMIners in the past and it was a fire hazard.

I have 6 sp20 coming in this week! Fast shipping and these guys take credit card, so no risk!

I wish you guys would bring the price.of the 30s down to compare with the sp20, such a huge price jump??

rack mount isn't worth the nearly double cost..

When's the next Gen coming???

Israel to USA 45066 in 4ish business days. Fell on a weekend so it felt stupid long

We're shipping within 24 hours of receiving payment. It usually takes 2-4 days.

how long did it take then?

Can't wait my 20s are scheduled to arrive today

IMO an SP20 can run at up to 1450GH with very reasonable noise at fan speed of <30%, a single wall between you and it is generally sufficeinet. if you want to be comfortable in the same room though, it needs to be <10% (or <1200GH)

but you'll never be able to get away with an SP3x unit - the power supplies are outrageously loud at anything over 70% load

A C1 is pretty quiet.  Just don't have it blowing right on you, it's kind of hot.

it mostly depends on your living situation and ambient temp in the "hashing" room. I currently have two SP20 (used to be three) and two S5 in one room, sitting on two circuits and hashing at 4.6-4.7Th. Sp20 are undeclocked at auto fan and fan 10 (third one was on auto too), S5 modded with Noctua NF-12 3000rpm (push, PWM) and Scythe Ultra kaze (pull, molex). power use-~2.5kw.
This setup gives out a very modest noise level throught the house as i have two other family members and nobody complains about it.
I wouldn't put this setup in my bedroom or office, though; I tried to put one machine in the office and it was brutal.

I get jealous some times knowing I can't buy the larger rigs. Even over electricity I'm more concerned about noise. Not a temporary fan change or a duct tape job, I do really need it quiet.

got the same shit:
Feb  6 11:59:20 miner local1.warn minergate[6949]: Critical: Lazy ASIC [2] - consider disabling it if this happens more then every 10 minutes

now my settings are:
Temp Front / Back T,B    12 °C / 55,54 °C
Fan Speed    70
Start Voltage    0.67 / 0.67 / 0.67 / 0.67
Max Voltage    0.72
Max Watts    220 / 220 / 220 / 220
Mining Rate: 1439.78Ghs

don't bother about the temp it's ok at higher temps

for me it was 1 asic, but still when disabled it didn't matter cause the hash was the same as with it enabled

Hard reset => fixed
