Anyone have firmware that removes the auto frequency and allows any kind of tuning to freq or voltage?
Does not exist.
 As has oft been said before: Auto-tune exists so Bitmain can use all the rather variable performing dies (chips) they can get from each wafer produced by TSMC. By being able to have each hash board run  at its 'optimum" (in my book - run reliably at all) Vcore/freq/Temp settings Bitmain is able to mix and match different performing boards to produce advertised specs. Once Auto-tune finds those volts/freq/temp settings per-board that it thinks are best the information is stored in the PIC of each hashboard for faster reboots (methinks).

And I too picked up another R4 batch 6 today since BTC is over $900 again Smiley
Need it to replace the 2 s7's I've been running at home for Winter heating. Just too power hungry at 15-cents/kWh even if they do reduce the gas bill.. At least the 2x early batch s9's in the basement still fully pay for their feed and more.

So far very happy with the batch 4 I picked up earlier which is running silently sitting in my office by my desk.

Phil, hope your percentage is better than mine... Got 2 R4's, one is hashing on one board so total of only 75% of the hashrate I paid for, and 50% failure rate (for this small sample size tho)  Sad

Yeah  I would hate for it to break.

I got very lucky with timing the purchase.

I paid 1.091  when I first checked it was 1.21 btc  yesterday's rally to 915 a coin   dropped me to 1.091 ,

Basically  I saved over 80 dollars by good timing.

Ah what wonderful timing.... Of course CNY is very soon starting and....

Yesterday got my 1st R4 batch-6 that I ordered last week. Was running perfectly with amazingly smooth hashrate. Emphasis on was... After 22hrs the top board (chain-8) now at best reports 55 chips vs the normal 63 and does not report temps. The 2nd batch-6 I ordered shows as being picked and will prolly ship tomorrow. Hope it fares better...

Still the same amazingly smooth hashrate though, banging around 5-5.7THs of course mostly from the good board (4.4THs) vs bad board of 1-1.4THs. The top 2 with their variance are what I normally see from ALL of my s9's. The start-stops seen are from my testing to verify bad board. Even my R4 batch-4 shows the same spikey throughput as the s9's but the R4 batch-6... scarily smooth.

Lovely time to start the RMA process eh?



To save space, links to screen shots of tests I ran. Tried soft-boot, hard-boot, and swapped data cables between top board (chain-8) and bottom board (chain-7).
Yes I know the logs show the chains as 6 and 7 but whatever. The GUI calls them 7 and 8 and so will I.

 This will of course be part of the info I send Bitmain as will be the interesting Kernel Logs resulting from the tests. All of the logs below are massively snipped to stay under forum size limits. However the full logs show very extensive logging going on - right down to the number of good cores per-chip. along with which core number(s) is bad in each chip(s). Very nice to see that!

After soft boot
Code:
Problem 22hrs after getting it on 1-18-2017: Chain-8 (top board) reporting very low temp and only hashing ~1.4THs vs expected 4.4THs

Kernal log after soft-boot, Chain-8 (top board) reports dead with no chips. Logs are snipped to keep under Forum msg size limits.

Note the absence of 1 board...
--------------------------------------------------------------------------------

After hard-boot
Code:
Following the results of a soft-boot (chain-8 not hashing at all) did a hard-boot.

Kernal log after hard-boot, at least this has chain-8 back to partially working (@ 1.4THs vs expected >4.4THs):


<massive snip>
chain[6]: All chip cores are opened OK!
Test Patten on chain[6]: OK!
chain[7]: some chip cores are not opened FAILED!

Chain[6] Chip[4] local Temp=59
Chain[6] Chip[4] middle Temp=99
FAN PWM: 64

Chain-8 is partly back running 1.4THs.
--------------------------------------------------------------------------------

Data cable swapped between top and bottom boards, hard-boot, problem follows top board
Code:
Kernal log after swapping data cables between boards and hard-boot. As expected reporting followed the bad (top) board. Bad board again running only ~1THs.
<massive snip>
chain[6]: some chip cores are not opened FAILED!
Test Patten on chain[6]: FAILED!
chain[7]: All chip cores are opened OK!
Test Patten on chain[7]: OK!

Chain[7] Chip[4] local Temp=61
Chain[7] Chip[4] middle Temp=104
FAN PWM: 65

---------------------------------
As expected error followed the top board.
Put data cables back as normal, now orginal error back with chain-8 hashing at ~1.4THs, no temps reported for it.

QUESTION ON RETURN TO BITMAIN

R4 failure 2 days out of the box. Ordered 2 units one working great, the second shows status view and log below.



End of Kernel Log:
total valid nonce number:57456

Chain[7] Chip[4] local Temp=47
Chain[7] Chip[4] middle Temp=68
FAN PWM: 62

I shook unit and listened for loose heat sinks before powering. There were none.

I upgraded to the latest firmware
File System Version   Fri Dec 2 00:35:43 EST 2016
and followed instructions that Bitmain provided to others earlier.

I'm getting the normal "green" LED, have both boards still hooked up and drawing 708W at the wall at the hash rate of 4.3 TH/s.

Reviewing return policy on Bitmain site and notes in this topic are confusing. When I try to put in a support ticket they want the tracking info but I'm not even sure where or what to send.

Do I send the whole R4 in or just the bad board?

Do I ship to China address and does Bitmain pay for shipping or do I?

Help please Bitmain

They will most likely ask you to pay shipping to return it.  You have to return the entire machine.  Depending on your shipping quote, you may also consider bitmainwarranty.com, which will probably charge you about $200 for the repair and you will get it back faster...

QUESTION ON RETURN TO BITMAIN

Help please Bitmain


Everything I have had to ship back to China for warranty repair I had to pay the shipping. It was an S9 board and a controller. Shipping was expensive as a MF'r. And that was only a single board and a controller! BM paid the return shipping.

For the R4, I think you are supposed to return the whole unit. I can't imagine what that will cost.
Good luck.

Bad board, see below



Since it seems I have a bad board, I tried powering one board at a time (with controller powered) to reduce power load but I get no hashing. This was easy to do issue on S7s, but it seems like both boards need to be powered on the R4 to get anything. Is there a way to just power one board and controller to get the same hash as above at a lower power? Is anyone powering just one board?

I ran into the same issue.  This was my first thought as well.  I hooked up a 2nd PSU to the bad board and powered it that way, then once it was on, I just turned the power off on the 2nd PSU.  I found UPS wanted $400 to return the entire unit to China, which made bitmainwarranty.com cheaper, even though you have to pay for the repair.  It was also a very fast turnaround time.

Thanks all for the help. I finally did get it to hash with the single board by swapping the cables on the controller board and unplugging cable and power from bad board.

I sent an R4 into Bitmain Warranty repair a few weeks ago. Still have not heard back since they received it

Definitely worth spending a little extra money to buy a used R4 that has been verified to hash on both boards and not risk the DOA units from China

My older r4. Has dropped a board.

I will need to send it back to china I guess.

My new r4 came today and is working okay.

So I have 3/4 of the boards working.

Got my other R4 batch-6 today: so far so good, holding a very even 8.7-8.9THs and all temps under 100C

Interesting thing: My 1st batch-6 (which had a board crap out 22hrs after running it) which I got last Tuesday has firmware dated Dec. 2 2016 - same as what Bitmain has up on their site.

This new one firmware date is Dec 9  2016...
Hmm, beta testing on us customers again?  Huh

Yep, right spot. Yours is dated Nov 25, 2016

Just as with my 1st batch-6 (with bad board after 22hrs so is 1/2 speed, Dec 2 firmware), this latest batch-6 has eerily smooth hashrate compared to the s9's.
ref:

I wonder if it has to do with this bit of code the log spits out and the miner is per-chip tweaking to give advertised spec?
Code:
miner total rate=8898GH/s fixed rate=8700GH/s
The R4 Batch-4 in my main farm at work is just as rugged looking as those s9's are. Hmm...

@elokk,

Please check the reported tracking number.  Techs will manually handle your repair request but tracking number you reported may be wrong and there may have been internal mix up due to the information not matching up.

Internal data, it shows, it was received on the 9th but the tracking you provided shows, it was delivered in another state on the 11th.

chances are your R4 is ready to go out to you since the the 10th or the 11th this month but may have mismatch identifier (tracking) and sitting in the owner response required que.

P.S: (GENERAL ANNOUNCEMENT) please help us by using 1 same Ticket Number for support request on the same item.  Also, communication from 1 email address or one account is also very appreciated for expediting the process.   Burnt PCB is highly unlikely attain successful repair.
