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

[dogie]

Now is too late. I'm going to sleep. Maybe tomorrow...

p.s. can it brick my S5?

No, it can't brick it but you have to watch the temps (must be < 70C).
When you reboot, the modification will be gone, it is not persistent as it is not in the firmware.

As its a custom firmware, there is always a chance it can brick and then you'll have to send your controller in to be reflashed. You should also be vigilent and check nothing has been mixed in or changed by going through the source yourself.

And as a reminder, modifying the designed cooling system (by replacing fans or custom firmware) WILL invalidate your warranty. You should consider this a mod that you undertake at entirely your own risk.

As far as I am aware, bitmain's own firmware is the ONLY one documented (in these very threads!) as having bricked their own hardware. More to the point though, there are adequate warnings with the mods (hardware & software) to not warrant sensationalizing by dogie.

And NO, that mod can NOT brick your S5 as it will not even survive a reboot (I am working on a firmware mod that will persist on reboot though).

Is there a fix for the S5 getting stuck/not failing over to secondary pool, on Nicehash/Westhash when the p=price password is used in combination with #xnsub ?
I just confirmed it happened on 5 S5s overnight for around 7 hours.  0 accepted hash and did not fail over to second pool until I removed #xnsub.  Not sure if electricity was used or not, that would be terrible.

My SP20s are working now with this after the FW update, but my S5s which are much more numerous still stick on nicehash doing 0 accepted hash and not failing to the secondary pool if #xnsub is used while the p=price is not met.
Using Jan 7th Firmware for S5.
No other password arguments are used as that seems to break it for any ASIC

Do we have any reason to presume that either CGminer 4.8.0 or 4.9.0 provides extranonce.subscribe support?

It is very "convenient" for final consumers. Why don't Bitmain issue a technique of reflashing the controller at home in case of any failures?

[KeezAZA]

That would be a great idea.

Maybe Bitmain should have a manual or list of things that would state what actions would void the warranty.
Changing fans with less than x CFM.
If changing or modifity the firmware.
if OCing the device.


i know these units can OC well, but some users/owners dont factor in the effects of OCing.

In the end we will know what will/might/will not be covered under warranty.

Can I buy several controller boards seperately, just to have some spare parts for S5 owners here in Russia?

I forgot, you already can on S5s. The SD card slot IS active with special images, and when an SD card image is used, it replaces the flash firmware. I haven't personally tried it and haven't needed to walk anyone else through it, but I've been told it works.

Then, is this considered official?

I'm not sure if you're suggesting that that code is in the released firmware, or just on github.

It's in the release... for the S4 at least, coz setting --bitmain-homemode does slow the fan down.

[dog1965]

Yes slow down your fan and burn up your S5 in three easy steps lol lol lol 

I posted numerous post on how to get the fan noise down and looks like no one even read it. Now you guys are trying ridiculous mods to bring down fan speed instead of using common sense! You guys would not last two days in a Engineering field. Reading some post makes me LMAO!

I can't set a precedence on that so still assume it will invalidate the warranty.

yea right dogie you still did not explain how to do it because you really don't know.

[pekatete]

He heard a rumour ..... and unless he heard it before you, then it'll void your warranty. BE VERY SCARED!

Agreed he works for BITMAIN maybe this is there way of making more money. If they tell dogie then dogie tells everyone else then they will see a lot of s5 controller boards lol.

I guess I'm an idiot then since I didn't go out and waste money on a second fan, remove the shroud so junk can get sucked into the miner and potentially snap a fan blade (trust me they're fragile, received one broken during shipping). Been running lanfeusst's modified fan control file for about 24 hours now on one of my miners, RPM's still holding steady at 3360 and temps in the mid 50s and happy to report no spontaneous combustion has occurred. Oh and I've been and Engineer for 20+ years and have somehow survived more than 2 days at every job. Keep up the good work lanfeusst.

I asked you a question regarding your "shroud" mod a few pages back, but didn't receive an answer.  I'm trying again.  You achieved a decent noise level reduction by installing the shroud, which judging from your photo also removed the finger guard.  Given that removing the finger guard alone reduces the noise level, did you check how much reduction resulted from each of the two changes (shroud with guard, shroud w/o guard)?  That would be helpful to know!  Thanks!

EDIT: I just realized you responded to my earlier question with a PM.  Sorry I missed it, please ignore this post!
