hi

Did you see the pictures in those links i sent ,

if this is true that T19 and S19 have same type of the chip , same number of the chip used in one device and ,etc

how could this Possible that more frequency , more hashrate , less power ?



some thing is not correct in my opinion .

could anyone tell me what is the chip used in this device ?

in product specification not mention any type of this information like how many hashboard it has or how many chip is used in this . not even the frequency .

but i found a picture in product manual , but I'm not sure it's correct or not .


in this image i see 4 hashboard , each has 104 chips that works in 550 MHz frequency .

please let me know if this info is correct or not . and if you know what is the difference with S19 Hydro 3950$ with same amount of the hashboard and chip with little more frequency 600MHz .



is S19 Hydro use another type of the chip ?

please let me know what you think ? i am interest to but more than 100 pcs and if anyone want's 1 or 2pcs , i'll be happy to sell you when i get my shipment .
