Hello, I am awaiting receipt of my S9i 14 Th/s which is due for delivery this week. This will be my very first mining experience. (I look forward) ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Do you have any advice on the quality of the S9s? Is an S9i deemed more reliable than an S9, S9J, S9K, or others? Thank you in advance Mickael

S9i S9j both were good.
most s9 were good a few bad batches say 4-9 had issues.
S9k = terrible.
I assume it is used and if the seller was honest it should be good.

Thanks for your reply, I think the seller is honest. At least I bought it on EBay from a seller with good reviews. He told me that the miner was in good condition and that the Th/s was stable.
I will see that in the coming days
When you say S9K = terrible, do you mean terribly effective or terribly bad?
I am thinking of installing Braiins OS + and mining on SlushPool. I watched quite a few how-to videos for the setup! I hope I don't have too much trouble ... It is not always easy to translate into English and French. 😉

Terribly bad. They have a very high failure rate.

If you trust the seller always go for the S9J version, if you don't, then ask for the S9I version, avoid the original S9 unless it's cheaper by say 20-30%, and of course, avoid both S9k and S9SE like you avoid putting your wet fingers inside the electricity box.

Ok thank you,
If I sum up correctly, we must avoid the basic S9. Especially no S9K and S9SE. S9J is the best, and if not from S9J fall back on an S9I.
What do you think would be a fair price with power supply for a good S9J today?

Not quite accurate, it's more like this: DO NOT BUY S9k and S9SE. avoid S9 unless it's pretty cheap. If you trust the seller, go for S9j. if you don't trust the seller, go for S9i. The difference between I and J is really nothing at all, so all in all, it doesn't matter, but many sellers will put the S9j sticker on the S9 and sell it as S9j which they can't do with S9i, so unless you know the origin of the miner or truly trust the seller, S9i will be the best to buy. What do you think would be a fair price with power supply for a good S9J today?
Fair? in my standards? I can't tell, I have bought them as cheap as $40-50, it's too hard to stomach the fact that they go for about $500 today, on the 28th of last month I bought a few for a client at $450 each excluding shipping, BTC price was at about 47k, now we are up to 54-56k so my guess is that they are back to $500+ range in China.

I could get some s9j for 350+ shipping but I suspect they are false s9's.
Now I am in usa shipping is a killer and with trump tax I can only buy 2 units at a time.

I am 100% sure they are S9s with the J sticker, or S9j miner with S9 boards inside, at $350 per S9j they could just sell that in China at a much higher profit, so be careful when prices are too good to be true, always double-check with grace, scott and the other reliable resllers.

Why can't I put a label on an S9I versus an S9J? I thought there was no difference between them except by consumption.

No, they are slightly different in size, not the overall size but the heatsink size on both directions are different, shorter on one side and taller on the other, so you can't fit 3 S9 hash boards in an S9i case, it's easy to spot a fake S9i but not a fake S9j, hope that makes sense.

Okay, indeed that makes a lot of sense! I thought the few differences weren't visible (like maybe better quality chips, or just the cards themselves?) Thank you for all your info 😉

S3+ was the most reliable Bitmain machine I ever mined with.

I don't have any interest with Bitmain lol, but I have to say that my S9k works perfectly fine since a long time. Never had an issue, even if I bought it used from alibaba.
PS : OP j'ai vu que tu parles français. Pourquoi tu t'interesses particulièrement au S9 ? Tu ne penses pas qu'il vaut mieux regarder du coté de chez whatsminer ? Bonne journée à toi

Thank you in advance Mickael running S9i very good and stable running S9 so and so one s9 running with nicehash firmware is the most stable of all 30pcs I have my stolen account was a legentary account: lowbander80 mining since 2013 1JgddX4AWtLxn9G3hMFzR99CVcZk2U66mQ

one s9 running with nicehash firmware is the most stable of all 30pcs I have
This only because the miner is in a good condition, it would run just fine with the stock firmware, in other words, I don't think that nicehash firmware aka HiveOs is the reason why that miner is running stable. my stolen account was a legentary account: lowbander80 mining since 2013 1JgddX4AWtLxn9G3hMFzR99CVcZk2U66mQ Not that it matters to me at least I take all opinions equally regardless of the rank, in fact, many folks here who have legendary status and have been in this space for many years still don't understand the basics of bitcoin, but if for whatever reason you want to prove ownership of that addy you should at least sign a message.
