I think this graphic sums it up quite well.
I think getting your unit converted to chips and sending to technobit is a better option. If your BA unit dies do you trust them to repair the unit? Will they even do a repair or are you sol. Do you think they will be around in 6 months? I think technobit will be around alot longer than BA.
They are bleeding for money! They will be gone soon. So many useless parts since they can't build a miner that they are hawking them onto everyone else. Don't buy that shit! Even if it is a little more expensive, go with their competitors. Help put a nail in BA's coffin and stick in the ground where they deserve to go.
Hard to get rid of parts when you can't build a working miner I suppose.

I have to agree. Go with the competitors!
X1 doesn't have hardware voltage control like X3, and they also don't display Watts and Volts on their web interface (or LCD).
There is some limited software voltage control through SSH, but only allowing you to step down the voltage, not increase it.

Good, that's what I want !!! If I will tune parameters I'll let you know !!
In other news, I've finally received shipping confirmation of direct-from-BA order #8xx (paid mid-November) which is an X1.
Me too !!!
I hope to have voltage control implemented, anyone have some news about this

my order #28xx for a X3 has not even shipped out but yours has? crazy
We are running 10 Prospero X3 in our data center (20 units of 1Ths) and so far stability is quite bad. We have to reboot some machines every few hours, and one unit is not functionning at all already. Instead of having a theorical 20 THs, we average 16-17 THs / day (we don't have 24/7 presence to reboot machines all the time, nor have auto switching plugs).

No idea why it's not functioning all X-3 i tested were running for week without performance drop and above 1TH/S per case.
Also there is a problem with 1.8 update as i heard, that causes problems to X-3 makes them run not at full spec. Better not update to v1.8 and if you did wait for v1.9.
You can also check PSU for the ones that stopped working, looks like there has been some problems with original PSU supplied with X-3.

If you're changing caps, make sure the replacements have low ESR/low impedance and decent current capability. Incorrectly specced caps will either not perform properly, explode, or both. The Nichicons linked above look like a pretty good bet. If you want to test the ones you take out, buy one of the cheap (but excellent) LCR meters from eBay.

So BA is shipping late, sub par hardware that doesn't perform to expectations? Say it isn't so!

Looks like the caps are 10mm diameter with a 5mm lead spacing. Height is around 20mm, but there is plenty of room for taller ones if needed.
I'm getting these for replacements:

People shouldn't have to pay for replacements or have to fix an new product themselves. it should work perfectly from the box. i'm very concerned i'm still waiting to receive my batch 1 prosperoX-1s ordered in Dec, and the number of posts from people claiming they received broken sub standard units is unsettling.
Its bad enough the delays and being forced to accept an obsolete product, but something that doesn't even work or raises questions if its even safe to plug in and leave running and not going burn the house down or blow a fuse while i sleep...

It's alive. I finally had success hacking my dead X3 PSU so that I could attach an ATX power supply to it, and it's up and mining again, bulging caps and all.
I'm using an older Antec 1200W unit to power it. At first I saw it drawing 1460W from the wall, and after recovering from my surprise that it kept running, i quickly backed the settings off from 1200MHz to 1000MHz, and it settled around 1180W at the wall.
I had at first attached four 6-pin PCIe sockets each coming off a pair of 12-ga wires, but the connectors got too hot to touch after just a few minutes, so I added two more sockets. Now they just get warm to the touch.

Yes I know (now) I got the colors/polarity backwards. After a magic smoke incident I fixed it outside the unit, not wanting to resolder all those wires on the PCB. I really need to work on being less retarded when it comes to reading pinouts.
Soldering all that was a giant pain in the ass. I used 3 irons at once, and used a propane torch to help heat them more hotter.
Still no response from BA about a replacement PSU. I sure hope they don't ask me to send back the dead/hacked one first.
Assuming they don't try and deny warranty from what you just said but glad to see it's running again.I'm using an older Antec 1200W unit to power it.

I suppose if they wanted to be jerks they could try to do that.
Really though I didn't hack it at all until after the failure had occurred, and had they given me a timely response/replacement I would not have needed to hack it.
While they're at it they could send me a fixed backplane with good caps, but I doubt that will happen anytime soon given how swamped they appear to be, so I'll again have to take the matter into my own hands. At least caps are relatively cheap compared to a power supply, though before I can order replacements I will need to determine the lead spacing (5mm vs 7.5mm), which means removing the backplane, which means more downtime...

X1 or X3? Dispatched on the 18th, arrived today on the 20th in Europe. Kudos DHL
I had a phone call from DHL this evening regarding paying my import tax for a delivery, I called to inquire who it was from and it was from BA. I ordered a X1 directly from them back in November, I've had no emails from BA regarding my order at all so this came as a surprise.
I had requested a refund about a month ago but never heard anything back from them apart from their automated response about submitting a ticket. So I'll just sell my X1 on ebay when it turns up just to try and make the money back on it rather than waiting on ROI.
