ANTMINER S3+ Discussion and Support Thread

[Biodom]

PCIe connectors are supposed to be keyed to fit one way...unless, of course, it's forced in.

Well, I could easyly plug them in upside down and burn out S2's stock PSU. It's being repaired now. I never thought that this is possible to do with PCI-E connectors. 

sorry about that, but don't PCI-e connectors have latches to show orientation?

i have my s3 occupying all my power supplies. assuming that I need 2 EVGA 1300 plus one CX500-600 to run 5 S3 (overclocked), I will have to pay extra $380 at the minimum, so your math does not compute, pal.

Well ur not managing your PSUS to the max then i guess cause here is how my mine is set-up
I currently have 5 s3 Batch 3, 6 s1s
currently i have
3 s3 overclocked to 250 1 s1 undervolted on a 1300 EVGA psu 1272 Watts at wall
2 S3 overclocked to 250 3 S1 Undervolted on a 1300 EVGA PSU 1198 Watts at wall
2 S1 Overclocked on a 1300 EVGA PSU 928 Watts at wall

Your S3 unit exhibiting similar symptoms with two different and very capable PSUs (600W & 1300W) is not likely a PSU issue.  It's more like a connectivity/networking issue (red LED on) or perhaps, the unit itself is defective.

With a CX500, each of my S3s which are overclocked to 243.75M (491 GH/s) pulls 413WAC at the wall at 29C ambient room temperature.  At 85% efficiency (80 Plus Bronze), the S3 requires 351WDC from the CX500.  The CX500 has a maximum of 456WDC (38A) on it's single +12V rail.  Therefore, the S3 is only exerting a 77% load on the CX500's +12V rail which is very acceptable and still provides a lot of headroom.

The CX600 (similar efficiency as the CX500) has a maximum of 552WDC (46A) on its single +12V rail.  Therefore, the S3 would exert an even lower load on the CX600 at 64%.

I'm not sure what you meant by "crobar it" but if the CX500 is able to run an overclocked S3, it follows that the CX600 is even more capable of doing so and the numbers support that.

you could be right.  however an OC'd ant is drawing about 400 watts to have a 500w PSU at 80% of it's limit is no bueno.  by crobar, i meant to push it beyond its limits or to failure.  my 1300 PSU turned out to be faulty (blown cap).  the 600 still works well, just not well with my ant.   that has been my experience...YMMV.

Yeah, now I know that the latches are the guideline on the way to plug it correctly... I saw them right after short-curcuiting my PSU.  Shame on me...

that's dandy, but your calculation does not show any $$ for power supplies.

Just as a follow-up to my last post that I have the power issue resolved, the S3 is now configured and running smoothly, mining on 2 pools.  The CX600 seems perfectly capable of handling the S3, at least in this basic configuration.

Like I have already stated, if CX500s are able to handle my overclocked S3s (up to 41.7C or 107F ambient room temperature), the CX600 would be more capable.

I'm glad that you are now hashing.  Consider yourself lucky that you didn't fry your S3 or your PSU when you inadvertently connected the PCIe power connectors in the wrong orientation.

i have 2 S3 running off of CX750. One of them is overclocked to 237.5mhz with no problems. I did try pushing both to that but one runs hot at about 46-47c on stock speed. Really I need to open it up and check it out to see if I can bring those under control. Mind the old saying though, "if it ain't broken." I know bad attitude, I should look after my babies better.

At 29C ambient, an S3 at stock clock of 218.75M and an S3 OC'd to 237.5M draw 359WAC and 398WAC at the wall respectively with an 80 Plus Bronze PSU (CX500); a total of 757WAC.  At 85% efficiency, they require 643WDC from the CX750 which has a maximum of 744WDC (62A) on its single +12V rail.  Therefore, the load exerted by your S3s on the CX750's +12V rail is 86%.  It should still be fine as long as you keep it cool but the consensus is ideally <80% load (at least 20% headroom) especially for a 24/7 operation.  Just keep an eye on it from time to time and make sure the PCIe harnesses/cables don't get too hot.

S3 temps of 46-47C shouldn't be a concern (depending on ambient temp, of course).  My OC'd unit go up to 51C when ambient room temp rises to 41.7C (107F) and seem to not skip a beat.  However, re-torquing the heat sink screws to make sure they are safely snug and seated well could only help.  QC of these products is not exactly top-notch.

Seems as if Bitmaintech took over snowball.io and is offering now cloud mining... don't know, though, if this is good....

Only time will tell but it could easily turn in to another ghash.

PCI-e power connectors are keyed so they only fit one way. If it was possible, we'd have read dozens of stories just like this over the past year.

Unless you have gorilla-strength and are able to force square pegs into round holes, then it's impossible.

It's not a matter of whether I'm right or wrong.  I was merely stating facts together with sound numbers to back it up.

An 80% load is still acceptable and seems to be the consensus threshold of maximum load especially for a 24/7 operation.  However, I'm curious about how you equated 400WAC draw at the wall to represent an 80% load on a 500WDC PSU with an efficiency of 85%.  Perhaps, you're confusing AC wattage (at the wall) with DC wattage of the PSU and vice versa and not figuring in the efficiency factor on top of that.

Who knows. They are offering cloud mining, however:

The mining farm is located in Shenyang, China. It's extremely advantageous geographical conditions with about 33000 sq meters. The mining farm has a completely ventilation and fireproofing measures, and provide high speed internet access, so that the miner status can be real-time monitored to ensure the miner stable. There are over 5,000 AntMiner S2 being operated in the mining farm, and the hash rate of 4,000 AntMiner S2 were switched into HASHNEST.

And the fact that they charge 0.94925BTC for an S3 is kind of weird... as if they don't really want to sell their miners...

BMT has just acquired Hashnest today
and maybe we'll see some change price in the few days...
while the higher maintenance fees.. and ghs also pricey

we'll see something in the few days

Yep...:

Sept 1 2014 ..."BITMAIN is announcing the acquisition of Hsahnest.com – a cloud hash platform which was originally named Snowball Exchange (Snowball.io)." ...

Nasty changes are coming into the Crypto-world...IMHO...

BTC will be centralized by these factories
by the time, they'll mining for themselves, then BTC will dead like LTC (pillaged and killed)
