Antminer S19J Pro Should I go for it?

Hey fellow miners, I'm considering getting an Antminer S19J Pro (104 TH/s 3068W). Is there anything crucial I should know before I make the purchase? Like, are there any known problems, major glitches, or compatibility issues with other gear or mining pools? Also, what's the latest firmware out there and which software do you guys recommend? Any good step-by-step guides for someone who's never owned an Antminer before would be awesome. Looking forward to your helpful insights.

We already have some guide here for newbie you just need a little bit of research to find them. Anyway, check this link "First time/Small miner reference for getting started." About s19j I don't know if this unit is problematic but take note of flashing it because there are two types of control board on this unit.

Hi and thanks for your feedback. The link you provided is not new to me, unfortunately is not related to my question (plus very dusty). What exactly you mean by "take note of flashing", do you mean I should upgrade the firmware at the 1st step? Can you provide a link with more details on this? Thank you.

There are two types of s19j pro that bitmain released I heard many complaints about flashing this unit with the wrong firmware. The two types that I mean are the BB board and the zynq 7007 board. Sample this issue s19j PRO won't fully boot after firmware update." So make sure to check the control board to use the correct firmware before you flash it. And don't flash the unit if the miner is working fine; only flash the unit if the unit has some software issue.

Thanks a bunch for providing that information. Will keep an eye on it. Anyone else, something worth to know about this model ?

I have a few of the 110th S19Pro's 4 x of the S19A models have been running well over 6 months or so but I did have a single control board fail. Out of 5 other S19J Pro's 110th models I have had 2 issues with the control board not seeing the 3rd hashboard in the chain. 1 of which even has a charred control board straight from Bitmain... So my short term assessment is you need a bit of luck with the S19J Pro models whereas the S19A Pro's seem to be a bit more solid... Or maybe its just crappy luck

Much appreciate your feedback Sledge.

despite the hashrate and energy specs what is difference between s19 s19j s19j pro ? which s19 model is worth for buying except the most expensive s19 xp?

I think the XP is waaaay overpriced. s19s are mostly the same, but J is using a bit less power if I remember correctly. Check the specs at bitmain.
