ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH

[kmitz]

just letting people know, Zoomhash still has the s5's selling at $325 with cc, paypal and bitcoin as a payment option. will prob change fast but thought I'd let yah know. I don't work for them, just noticed they are the cheapest I've found right now

Thanks for the tip! I just ordered one S5 on Zoomhash. I checked here and there if they were legit...seems ok.

Finally didn't turn out well... My order for one S5
got cancelled 2 days after payment. Got an email from Zoomhash saying they don't have enough stock. But they debited my account anyway!
Now I'm nervously waiting for the refund...
Bad first experience in the mining world.

Edit: A least I'm not alone :-p

I have ordered twice via Zoomhash, once for S4(right before I learned about S5) and once for S5
Both times they took around 9 days to tell me they were out of stock and then took longer to refund the credit.
I no longer recommend them no matter what they offer, though I understand on the S5 deal, who wouldn't buy it at that price.

Zoomhash Sucks what A bummer! You think they would post "OUT OF STOCK" before people order it!

It seems they have no inventory but just drop ship from Bitmain after you order. Its a no lose thing for them then and a longer wait for the buyer. Also they can also keep any coupons I guess?

[kreativling]

For what it's worth, ZoomHash is still at $325 + shipping. They accept PayPal and Credit Cards. They claim 5 days shipping in the USA.

Alas this is not be. I got an E-mail from Zoom Hash less than 48 hours later saying that they had to cancel the order. So my "S5 for $348 shipped to Minnesota, paid with Discover" turned into a flop. They are crediting the money back. Bummer....... 

My shipment was canceled too. Even with a simple excel sheet I would be faster than 3 days to know what I have in Stock or not... Speechless...

like a said just do this mod you can make the shroud out of a old 120mm fan or just buy one make sure its 25mm or thicker it brings down the noise a hell of a lot!!!!!

You reported a respectable reduction in noise level with your mod.  Do you know how much of it is due to the added shroud Vs removal of the finger guard?  I understand removing the guard alone makes a fair difference.

I have marked the LM75 (TEMPERATURE Sensor) Chip in the following pic. Just stick a small heatsink on top of the sensors, one on each hashing board.

If you put a heatsink on the the sensor wouldn't that make the sensor inaccurate then? I mean you're cooling the sensor but not necessarily the board.

Pretty much, hence its not recommended. There are more things that require cooling on that board than just the ASICs, and if they didn't we'd be seeing a vastly different cooling setup.

"... more things that require cooling ..." - What are these more things? They surely must have a name if they exist, and would be visible in the image too! Or is it a case of secret components that only bitmain staff know about and have been sworn to secrecy?

Truth of the matter is that cooling the LM75 results in lower reported temps thus lower fan speeds (and noise). Add to that, there are no discernible components, on the side the LM75 is sited, that require that much cooling. On the chip side, well thats got the heatsink / waterblock.

More pertinent though is that the LM75 temps are used just to govern the fans. In the case of the chip core temps, that is handled by the control-board software. So basically, if there was a substantial reduction in cooling, that would result in higher board & chip core temps and should the chip core temps exceed the thermal cutoff specified in the (obfuscated) control board code, the board would not send work to the chip(s) until the core temps fell below the thermal cutoff, and that would manifest itself in a drop of hash-speed. Clearly, that has not happened to the people who've done these mods.

So, unless you can throw more light on these ".. more things that require cooling ..", I'll just have to put it down to the usual dogie-waffle.

is this what happens when it reaches 80 C or does this mean that it went above 80 C?  The unit still turns on and I can see that I have it set to turn off if it reaches 80 C, but it doesnt look like it did

The unit powers on and I can get to it via the network but it wont hash - I figured it out when I took the sides off and found the burned board.

I dont have any thermal events on my other miners.

Plastic cover looks warped from heat too, yikes.

I am not surprised it is not hashing anymore, string mode = one out, all out!
Looks like you had that running without any mods, i.e standard fan in push configuration, so, what PSU did you have on this?

[aclass]

This is just one hashing board right?
Disconnect it from the controller and see if the other one works

It's both ..... images of both sides have a burnt chip.

[aclass]

Gotcha. Strange thing to have it at once on the both sides

I agree .... which makes me think PSU.

[mavericklm]

Is the fan still working? looking at the sides i guess the fan is dead or something was wrong with the ventilation

[Tigggger]

Dear Bitmain,

I understand you guys/gals are really really busy and it's probably just an oversight

When BTC started rising the price of the S4/S5 went up, when it continued to rise they both went up again.

Now that BTC has dropped back down to it's previous level, the prices have remained the same which makes your products much worse value than a week ago.

No need to thank me for alerting you to this, you are welcome

Regards

ya, fan turns on - I am using a Thermaltake 850W 80 PLUS Bronze

Hi Bitmain,

The S5 is $0.32/GH without shipping; not $0.25.

That looks OK ..... if you happen to get an explanation out of bitmain (I am sure it is still within its warranty), do tell.
