Thought my pair of S5's would ship on 08 Jan. but got notice they shipped yesterday (via BitMain on Amazon).

Are those B3 ones direct from Bitmain? if so that's weird they would ship before B2.

The Amazon sale was linked to B2, which was scheduled to ship on Jan 4th if I recall. Amazon used different dates such a early February as the latest delivery date but they now have tracking information indicating that the shipping label has been made but they have not left the factory yet. UPS indicates a delivery of Jan 7th for the US west coast.

Thats totally messed up that they would ship batch 3 before batch two … from what I understand my batch 2 should ship on the 4th and my order status says unshipped … Who would have thunk that batch three would ship before batch two ...

They have not shipped. The amazon shipping notices and tracking #'s are just the UPS labels being printed.

Watch out for the "Neg-Rep-Dogie-Police".....

Following up from my earlier post about my half dead S5, I had a pleasant surprise when UPS came knocking on my door with a replacement hashing board today - I didn't even realise that BitmainWarranty had despatched it! Straight away I got to work, stripped the S5, removed the offending board, slid in the new one & put it back together - it didn't take long at all due to the "open air" design...... Cheesy

The result:

Running for 3 hours now without a hitch - lovely!

Respect & thanks are due to BitmainWarranty who was super fast in arranging the replacement board without a hassle, as well as friendly & understanding as usual, unlike a certain other "representative" - who should take a leaf out of BitmainWarranty's book on customer relations instead of barking at customers. If he did so, Bitmain & himself would be far better for it.

PS: Thanks for the T-Shirts & stickers also BitmainWarranty

Quick, clean and easy fan muffing for the those that have an S3+.
Swap the push fan from an S3+ with the stock S5 fan. At 3500 rpm, the S3+ fan hums (or purrs) whereas the stock S5 fan whines ..
On the orher hand, the stock S5 fan will run at a much lower rpm when strapped onto an S3, thus won't be as loud as when it is on an S5.

I tried with my s3 (not+) but the cabel from the fan is to short Angry

I have the s3 fan connected directly to the psu. So it is at full speed Sad

I am not sure if it is less loud. Roll Eyes

Gonna order some cables / adaptors now.

How does the current limiting on the PCIe plugs work, BTW? I'm not at home to check, but I would assume that the two plugs are not simply paralleled on the hashing board and that each 12V plug powers two of the ASICs in a loop.
IE, if you disabled a full loop on a hashing board you'd pull full power from one plug, and ~0W from the other.

Is that correct?

the sp20 seems to be 1 plug per loop. so if you knock a plug loose on 1 board(each board has 2 loops) the board only allows 1 loop to work. this is good and it is safe.
I have knocked loose a pcie cable at the psu end and the sp20 just ran 1 loop on that board.

problem is that the S5 will put about 270-320W per blade, so if you use two seperate cables thats a managable 150W/cable. If one fails, that 300W will push a cable to its limit. 16awg can handle that but an 18awg will certainly fail.

in comparison, the SP20 can draw up to 288W PER CABLE at full speed. (~150W/cable underclocked). Not much difference in safety as far as I see, if anything the SP20 is more likely to cause PSU failures (in lower quality supplies).

dont use a Bronze or lower PSU for either device, thats my suggestion. GOLD or PLAT power supplies will have better safety features and use thick wiring in its cables. Alternatively, I sell 16AWG PCIe cables that have either a connector on each end, or a connector at one end and stripped wires for server mods on the other. Ive used them to carry up to 312W each at which point they get warm but not hot

using Corsair CX750M on S5 at 325 setting (disliked the sound of fans at 350) and regular fan (Vornado) blowing in the same direction as the internal fan, temperatures (other than boards) were measured by the laser probe:
Ambient 27-28C
miner boards temp 48-49C
hashing at ~1070Gh/s
Connector at PSU- 29C
First 10-15 cm of wire-33C (interesting!), the rest of the wire 28-29C
Connector on S5 closest to the internal fan-29C
Connector on S5 farthest from internal fan-33C (interesting)
each branch of the branched PCIe is connected to the same board (same side of the miner)
this looks safe at least as far as at connectors temperature is concerned
later I will test with 325 and no external fan, then 350 with an external fan, then (maybe) 350 without an external fan

bitmain, if your going to remove the listings of batch 1 through batch whatever, can you please find a way to leave the ship date for each batch . I ordered batch two and went back to the page to reference the batch two ship date and its gone … I'm fine with removing it if the ship date has passed but by removing the ship date prior to the actual ship date makes it look as if you are trying to make the ship date a moving target based on your needs as opposed to customer needs .

Is the ship date not on your order confirmation or invoice?

'The right to privacy matters'

okay fast opinion on the two gears (s-5 , sp-20) safety .

both are far safer then AM's prisma was when it first came out.

both can fuck up by melting cables.

melting pcie cables happen for more then one reason.

1) bad management by the operator. ie overloading a cable beyond its specs.
2) poor cables
3) defective cables
4) defective psu's

I can see multiple ways to set up the s-5 or the sp20 that result in overloaded cables. --- that is operator error.

And we all know some psu's are not good
and we all know some cables are not good.

frankly use common sense as both units suck down a lot of power on the pcie cables.

... speaking of overclocking, here's some figures from overnight testing. This is using the stock push fan, with an additional pull fan added (although I question whether the pull fan is making any difference at all...)

I've found, in my testing so far, that keeping the board temperatures <60C is required for stability. Room ambient temperature is 24C where the miners are working.

Well I have decided enough of the fan is too loud and I am now going overclock.

I placed the loud fan back in the original spot opened a window in the bedroom it runs in. The intake air is now about 50f or 10 c

I added a second fan a 3 pin delta the can blow 148 cfm since it is 3 pin it runs 2800 rpm to 3200 rpm and I put the S-5 at freq 375

the noise is nuts and I won't be able to run this gear with this noise,but many people can run the gear in a shed or a barn and do not care about noise.

this is a 10 minute run at freq 375 very nice numbers

http://imagizer.imageshack.us/v2/1024x768q90/661/gOZWdC.png

mine gave a board of all x's when i tried it at 375 Undecided

Something which will happen on these miners that we haven't seen before is PSUs matter more than ever. There is going to a be a big difference in power consumption and overclockability depending if a perosn's PSU is 12.2V under load or 11.6V.

yeah using the single evga 1300 g2 for just the one miner I am getting over 1307gh the mod was add a decent delta purchased on ebay for 10 bucks.

I can not run this at the noise level it does but many can.

At 1307 gh and watts at the kwatt meter at 692 692/1307 = .529 watts per gh at the kwatt meter

1 hour test at 412 is good.

do a reboot . one issue is this seems to happen on higher clocks and a system reboot via gui has seemed to work.

this miner looks good to overclock in a cold room with a second fan . and thinking fuck the noise.

I will boost to 400 in a bit

to be honest i'm happy at 980+GH/s at 300. temps are comfortable - and i don't need to worry about the noise as it's outside in the cold

I think in my setup I would max out with that number.

Stock fan in the push and a delta 3 pin in the pull.
I think the stock fan at 4000 rpm moves 200cfm the delta at 3000 rpm in the pull moves 148cfm
At these speed it is not a home miner. it is about 79db and nasty sounding.

But the numbers below are really nice
