R4 running at half speed, chip status looks strange.

[Entropize]

I'm having an issue that I'm wondering if anyone has seen before. I ordered 2 R4s in January and set them up on my local network monitor which I guess gave me a false sense of security because they've both been live on the network but apparently one stopped working some time ago.

When I logged into it the GH/S(RT) said 0.00000 and one of the boards has no temp info. I tried a software restart a few times to no avail and after cycling power I now get one board running and ~4.7TH/s so half output.


Has anyone seen this before and found a fix? Trying to upload the .tar.gz for R4 firmware from the antminer site fails.

I have 3 days left until I'm out of the 90 day warranty window expires but shipping this thing to china seems like a bit much.

[HagssFIN]

You most likely have a faulty hash board.
--> warranty repair.

[VRobb]

If you ordered them in January you have a 180 day warranty period, not 90.

[Entropize]

That's great news, now I don't have to scramble to get this all set up to return in the next 2 days.

Yes, but it sucks.  You have to send the ENTIRE unit back to China.  I would recommend sending to Denver (It's not free but shipping was going to cost me almost 300$$!)

My unit was back in 13 days.

We now offer comp mining while unit is in paid repair.  If it is not fixable, we will stop the comp mining upon discovery of none fixable condition and let you know!

At least that will remove new miners confusion between your company and Bitmain.com
Will you also be handing North American in-warranty repair for them as well?

So I have a dead board on one r4.
What do I send you the dead board or the whole unit.
I am in New Jersey USA

@philipma1957

You can send in just the bad hash PCB if other is working, or you can send the whole unit, whichever you prefer.

Thank you

I will do this later today.  I will send in dead board.

I already have an account with BitmainWarranty, does that registration automatically switch over to MyRig or do I have to re-register?
Also have a s9 board shipping out to you tomorrow.

[MyRig]

@NotFuzzyWarm

the comp hashing needs, that system be a different account and requires 2FA

eventually, consolidate them but sorry for the mess in transition

at least how it will work, if you are shipping hash PCB for repair, please give us your feedback how the whole process can be improved to work with all level of miners.  (commercial, hobby, home miners, and etc...)

the piece of paper you insert in the box, please MARK, (BETA TESTER) in BOLD and techs will give you the discount on repair for you to give us feedback good or bad or nasty or troll... whatever it is.

Thank you

The s9 board is already on it's way. I will leave a note on Zendesk to ask if it can be flagged as BETA TESTER.

 No matter what I will do that when I send in the dead R4 board.

One thing I can ask for improving service: Tell us what was wrong/fixed! In the past the excuse for not doing it has always been that the tech report system is not setup to do that. Huh?

Whenever I do a repair be it in the field or in-house I create a detailed list of what was done. It is done both for the customer records and more importantly for my companies records so we can track failures/causes..

The tech report does not have to be detailed but at least list what was found and done to correct eg, 'bad PIC - reprogrammed' or 'no Vcore - replaced MOSFET', or whatever.

[MyRig]

Thank you for the suggestions.  We will try our best to reach that point in service, hopefully one of these days, we will meet this request!

Most ask for lowest repair cost as possible as fast as possible.  Speed part, to reduce the frustration, we are implementing the comp mining option as OPT-IN for the customers.

Any update?

I just had one of my boards go on one of my R4s this morning.

I am just starting to see what I need to do / best way to get it fixed.

[xuy]

Check kernel log. I see this error in my R4 kernel log;

total valid nonce number:57456
total send work number:57456
require valid nonce number:57456
repeated_nonce_num:0

The status shows one board or sometimes it shows 2 boards but avg hash rate is half.

Mine looks very similar, even though I do not know what some of it means.

I would show a screenshot, but i do not know how to do that on this forum.

Mi miner status essentially shows chain 7 not working, only 550 gh/s vs norm of about 4,350 and no chip temps for this chain/board.

[xuy]

If you read through the log,  you may get some sense. There are 2 chains and each for one hash board. If one chain fails, the hash board won't work. But I am not sure the exact reason. It might be just one simple fix, not replacing the board. During reboot, all chips will be pinged to test. In my case, only one hash board is passed test. Low temperature means no hashing.
