Title: Black Arrow Prospero X-3 - thoughts and feelings? Post by: rez303 on March 15, 2015, 06:25:48 PM Hello, bitcoiners! I've been given the opportunity to purchase a Prospero X-3, made by Black Arrow. There isn't a review for them on popular sites, nor are there many comments on videos past "It's big and loud." I'm aware that BA has had problems with their MOSFETs causing hashing boards to burn, but the owner has said he recieved it a year late because they've fixed such problems. I've requested him to run the X-3 for a few days, and so far, so loud, so good. So, are there any X-3 owners? If so, what can you tell me about their performance, reliability, and stability? And, if given the chance, would you trade it for a pair of Bitmain Antminer S3's? Thank you for any help you can give me :)

BA has just gotten a pretty bad name on it as a company. Title: Re: Black Arrow Prospero X-3 - thoughts and feelings? Post by: Syke on March 16, 2015, 02:28:56 AM Hello, bitcoiners!

BA's claim of "fixing problems" has turned out to be flat out lies. Title: Re: Black Arrow Prospero X-3 - thoughts and feelings? Post by: Jamphone on March 16, 2015, 02:38:33 AM Hello, bitcoiners!

BA's claim of "fixing problems" has turned out to be flat out lies. I think that sums it up. At my mine, we found one out of two showed up broken, and sometimes not obviously, ie. plug it in for thirty minutes and then smell the burning. In fairness, the other 50% are still mining away, albeit at a terrible watts/gh. Title: Re: Black Arrow Prospero X-3 - thoughts and feelings? Post by: Bicknellski on May 17, 2015, 06:52:25 AM What sort of value do these units have actually if they are on sale?
Given the fact they are risky to run what sort of price should they sold at currently? Title: Re: Black Arrow Prospero X-3 - thoughts and feelings? Post by: mikenekro on May 17, 2015, 07:20:46 PM I have seen some of them sell on eBay for around $300-$350 within the past month or 2.
I have had one for 2 months running 24/7. It's stable and has shown no signs of blowing up. I purchased it from a guy on eBay and got a good price for it. He got it from BA and sold them immediately because of that whole situation. It is the batch from February. It never hashes below 995ghs and averages about 1010ghs. For power, it does use up about $45-$60 a month where I am. So there's been a little head room. I'm selling mine soon as I will be able to get most, if not all, what I played for it back. It's a fun machine to look at and take apart to see what's inside. But if you're in it exclusively for profit, you could do better. Title: Re: Black Arrow Prospero X-3 - thoughts and feelings?
