SP20 Jackson 1.7 TH/s ★ Bitcoin ASIC Home Miner Spondoolies-Tech Israel ( www.spondoolies-tech.com ) SP20 Tech Demo & Report by Reptor ( www.youtube.com/ReptorULTRA7 ) My SP20 Hardware DEMO : http://www.youtube.com/watch?v=0U9zNHO3X8o My Crypto Playlist : http://www.youtube.com/playlist?list=PLapYrvLsD91sL1U3TVGpA4k-L31sEx8At In January 2015 I had the opportunity to buy and test my first "SP20 Jackson" Bitcoin Miner! Spondoolies already started to sell/ship the units in Nov 2014. The SP20 is currently the best ASIC hardware miner available on the market for serious home users who intend to mine Bitcoin BTC and other SHA256-based coins effectively despite rising mining difficulty. Spondoolies have also released their SP30 Series (SP31 & SP35 Yukon) for users and professional companies out there who build big mining farms and centers. With dropping prices the units start to become affordable to even home users. Here are my current stats after approx. 6 hours (1/4 of a day) of test mining : ================================================================================ Bitcoin BTC Stats ================================================================================ Current Mining Diff : 41,272,873,895 Next Mining Diff : 40,244,179,486 Mining Diff is decreasing in 2015 (!) due to mining companies and home miners taking old and outdated hardware offline. This is a good chance for serious miners to start mining with latest hardware, such as SP20, during this year...! ================================================================================ SP20 Mining Stats : ================================================================================ Hardware Version : SP20 Jackson Firmware Version : 2.5.2 CGMiner Version : cgminer4.7.0 CGMiner Uptime: 6 hr 39 min Miner time : Thu, 29 Jan 2015 21:57 (Europe/Berlin CET +01:00) GH/s Range : 1602.87 .. 1658.84 (effective mining hashrate w/current settings) Best Share : 5510509 Accepted Shares : 8840 (approx. 1383 Shares/hr) Rejected Shares : 12 (2 Rejects/hr) Errors : 0 (see actual hw-err amount in ASIC stats below) ================================================================================ SP20 Voltage & Overclock Settings + PSU Power Supply Unit : ================================================================================ Temp Front / Back T,B : 30 °C / 80,77 °C (Winter Time, Medium Warm Room) Fan Speed : 90 (max. 100) Start Voltage : 0.67 / 0.67 / 0.67 / 0.67 (min. 0.64) Max Voltage : 0.73 (max. 0.79) Max Watts : 1350 / 1350 / 1350 / 1350 PSU : 1 x EVGA SuperNova 1300 G2 (can be overclocked to 1350W) ================================================================================ ASIC Stats : ================================================================================ Uptime:23160 | FPGA ver:100 -----BOARD-0----- PSU[UNKNOWN]: 0->271w[270 271 270] (->271w[270 271 270]) (lim=1350) 0c cooling:0/0xcc -----BOARD-1----- PSU[UNKNOWN]: 0->233w[233 233 233] (->233w[233 233 233]) (lim=1350) 0c cooling:0/0xcc -----BOARD-2----- PSU[UNKNOWN]: 0->278w[278 278 278] (->278w[278 278 278]) (lim=1350) 0c cooling:0/0xcc -----BOARD-3----- PSU[UNKNOWN]: 0->227w[227 227 227] (->227w[227 227 227]) (lim=1350) 0c cooling:0/0xcc LOOP[0] ON 0: DC2DC/1/:[vlt1:708 vlt2:714(DCl:794 Tl:794 Ul:727) 107W 150A 72c] ASIC:[ 85c (125c) 1090hz(BL:1105) 1122 (E:193) F:0] 1: DC2DC/1/:[vlt1:724 vlt2:727(DCl:794 Tl:794 Ul:727) 103W 142A 90c] ASIC:[100c (125c) 1040hz(BL:1040) 1050 (E:193) F:0] LOOP[1] ON 2: DC2DC/1/:[vlt1:685 vlt2:690(DCl:794 Tl:690 Ul:727) 93W 136A 94c] ASIC:[120c (125c) 1005hz(BL:1005) 1032 (E:193) F:0] 3: DC2DC/1/:[vlt1:664 vlt2:666(DCl:794 Tl:666 Ul:727) 87W 131A 100c] ASIC:[120c (125c) 1005hz(BL:1005) 1032 (E:193) F:0] LOOP[2] ON 4: DC2DC/1/:[vlt1:722 vlt2:727(DCl:794 Tl:794 Ul:727) 107W 147A 73c] ASIC:[100c (125c) 1095hz(BL:1095) 1133 (E:193) F:0] 5: DC2DC/1/:[vlt1:724 vlt2:727(DCl:794 Tl:794 Ul:727) 110W 151A 89c] ASIC:[105c (125c) 1095hz(BL:1095) 1146 (E:193) F:0] LOOP[3] ON 6: DC2DC/1/:[vlt1:673 vlt2:680(DCl:794 Tl:680 Ul:727) 89W 131A 89c] ASIC:[120c (125c) 1020hz(BL:1020) 1033 (E:190) F:0] 7: DC2DC/1/:[vlt1:671 vlt2:677(DCl:794 Tl:677 Ul:727) 86W 128A 94c] ASIC:[120c (125c) 980hz(BL: 980) 1022 (E:193) F:0] [H:HW:1607Gh,W:785,L:0,A:8,MMtmp:0 TMP:(30)=>=>=>(80,77)] Pushed 28 jobs , in HW queue 4 jobs (sw:1, hw:1)! min:50 wins:8570[this/last min:21/36] bist-fail:130, hw-err:23 leading-zeroes:42 idle promils[s/m]:0/0, rate:2516gh/s asic-count:8 (hashrate peak @ 2.5 TH/s!)

Effective hashrate is displayed as [H:HW:xxxxGh]. See above. According to Spondoolies Software Director Zvi Shteingart the effective hashrate can be increased to 1.9 TH/s with two "EVGA SuperNova 1300 G2" PSU's powering up one SP20 unit and experimenting with various voltage settings. I haven't tested this yet. So far I'm running steady at effective 1.6x TH/s with one EVGA PSU. -- Reptor [DA2K] 1/2015
