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

[PatMan]

From my experience so far with the S5, the dreaded X's don't always show up - the hash rate just halves due to one card "freezing" so to speak, so even mdudes monitor can't detect/reboot it. The only way of knowing is to constantly check the pool hash rate, which is a pain in the face

Major. Pain. In. The. @$$!!!

A workaround could be to join a pool that has a "hash-rate-drop-warning" system in place (like an email or something that alerts you pro-actively when the hash rate drops)...

[dogie]

..... as the S5's require a reboot pretty often due to a firmware issue that makes one hash board drop off every other day.....

@ Bitmain:  Any news on a firmware fix for this in the near future?

I can't imagine buying multiple units until this is fixed, it's bad enough having to babysit the one unit.

Do you think this can be fixed with software or is it maybe inherent to the "chain design" implemented in the S5 hardware?

Personally, I think it's a firmware issue - maybe if Bitmain would confirm......

This is the first I heard of this and I have a batch 3 order so shipping any time now.  Is everyone experiencing this?  Does restarting cgminer fix it temporarily?  I have a batch 2 S3 that needs a ton of babysitting also because the hashrate drifts lower and lower the longer it runs, so what I finally did was create a cron job to restart cgminer.  I originally did a cron job to reboot the thing but one time it rebooted and got all hosed up and didn't mine at all for hours so I just restart cgminer now. 

Its already confirmed:

Overnight, one of the blades curiously went xxxxxx xxxxxxxx xxxxxxxx xxxxxxo running at stock 350 with the temps at 63C. Rebooted and it's working OK again.

Hmmm.....I got back from New Years Eve celebrations earlier and noticed the same thing with mine, but all X's. They all came back after a reboot also, but it is a little worrying.....   Anyone else had this?

that's alarming...

There is a known firmware bug where one module drops out but both still display as mining and temperatures fixed. This may be the same bug and will be fixed in the next one. And yes, its very much firmware.

ie: Babysit it.....It shouldn't be necessary, especially with a brand new unit. Some one with multiple units will have to be at their farm 24/7 rebooting......that's mad.

So when you say "fixed in the next one" does that mean batch 2 or the next firmware version whenever that is?  And is this the same firmware we can update at home (whenever it is released)?

Firmware (not guaranteed to be next, more 'soon') and yes normal firmware you flash via web browser.

This is the thing, if history is anything to go by with the S2, S3 & S4 firmware problems - it could take months to get the S5 firmware right, if they do at all. This is the major drawback with Bitmain, great units but buggy firmware. Compare this to SPT, they are constantly testing & tweaking their firmware to improve it - not to get it working properly.

Bitmain & Firmware......

(SOLD) I have two S5 coupons up for grabs, 1 is for $40 & the other is for $45. Please PM me if you are interested.

You hit that dead on! Always seems like a gamble early on with Bitmain.

S5 firmware is being tested tonight, estimated to be online tomorrow or the following day.

My Batch 2 miner arrives today... on truck for delivery.

That's great, thank you for confirming.

Can you also confirm that it will incorporate the cgminer fix that ckolivas has mentioned here:

Here's a quick binary for the S5 based on bitmain's existing code which will ignore any queue parameter, not discard stales, should be able to ramp up smoothly if you find yourself on a very low diff pool, and use a little less CPU:

http://ck.kolivas.org/apps/cgminer/antminer/s5/4.9.0-150105/cgminer

Binaries will only be temporary so will not survive a machine reboot.

The following will change the cgminer binary for you (set the appropriate IP address), the default root password is "admin":

Code:

ssh 192.168.1.x -l root
cd /tmp
wget http://ck.kolivas.org/apps/cgminer/antminer/s5/4.9.0-150105/cgminer
chmod +x cgminer
mv /usr/bin/cgminer /usr/bin/cgminer.bak
cp cgminer /usr/bin
/etc/init.d/cgminer.sh restart

There should be a more comprehensive merge in the future into mainline cgminer, hopefully by Kano. Bitmaintech has provided us both with S5s to support cgminer development.

Thus saving your customers having to re-download & install it after every reboot?

Thanks

If anyone is not going to use their coupons, I'm looking for 2, please PM me.

Thanks

what else to expect from a plastic miner...

[klondike_bar]

what else to expect from a plastic miner...

not sure why the sides being made of a good quality, lightweight plastic is a bad thing. Its better than the S1, and far lighter than the S3, but really needs a top cover.

the burnt component on that machine looks like a regulator for the control board - not sure for what, possibly the 5V power source of the Beaglebone.

Janet, As PatMan as requested as well, can we please get the cgminer fix that ckolivas has already provided the community?

will this address the PWM functions of the fan? Would be nice to see a way to manually set the fan, or at least to set a temperature target (at stock, temperatures seem to be targeting 50C or less - setting that to 55C or 60C would drastically reduce the fan speed/noise)

[MyRig]

Thank you for the suggestions!  will pass these on to the engineers.  (these changes unfortunately don't happen overnight tho...    )

got a raspberry pi on the way and awaiting my batch 3 review unit Pretty excited tbh!
