1024 or 2048 should work well, higher than that and you're just burning shares on discards.

okay got my S5's in today no SD cards are in the slots

these dont come with SD cards? or did bitmain mess up?

should i put one in?

if so how do i put a image on the SD card i got a few laying around and have download win32 disk imager and the image from bitmain

sorry this confuses me all my other miner have sd cards.

I knew these did not have a top on the case but they dont have a bottom either? WTF!!!!

These are a nightmare to fit into my current exhaust configuration, going to spend all evening making proper cases for these. Seriously bitmain could you go any cheaper? I am not impressed!!!!!

okay think i figured out how to do the image have to read the image first then write it
first time i just selected the image from location and pressed write. Now that i pressed read first then write is doing something

Thanks dogie I was thinking bitmain messed up
So they SD card slot is for restoring things if they go wrong?

I heard that it's enough just to insert a SD card with C1/S4 firmware on it and boot up your S5, then you will need to update a FW to latest (or custom...) version for S5.

Hello everyone!Just a newbie miner question i bought an antminer s5 and for psu a corsair rm850 i also bought 2 fans corsair, one sp120 and one af120 and i want to plug them with psu to operate full all time.... my question may sound stupid but i want to ask where i have to plug it as i didnt found any cable for those in corsair psu box.What cables (adaptors) i need to buy to work with my psu?One is 4 pin and the other is 3pin.Any advice will be appreciate it.

Kind Regards,
BTC-Bank.

My appologies i was in hurry..I am asking for what cables/adopters i need from psu to (extra) 2 fans wich one is 3pin and other 4pin wich i will use for antminer s5.  :-) i want to replace the original as it is too loud!

I tried the fan (4pin) direct on s5 but is not stable goes from 1600rpm to 2160 rpm and i want it to work full runing all the time so this is the reason i am looking from psu to fans direct.Thank you for your responce!

Kind Regards,

Corsair sp120 high performance + af120 silent for a small test i made was very silent but i don't know how it will work for many hours or if they will be any problems for the s5 as i didnt buy the cable to connect them to psu yet..From my search i think this is the best solution but you can try it in my opinion with 2 sp120 as they are more powerful but silent too, i think it will be much better.

rpm for sp120 and af120 it will be around 3.360

Kind Regards,

AF120 is 1650RPM with moderate static pressure, which is too low for an S5. 2 SP120s works in sensible ambients and benefits from taping the heatsinks closed (top and bottom). Its going to run hotter than stock (60-65) but thats fine and its the closest you can get to a silent S5.
