Just fired up first R4

Latest FW was on device
File System Version   Fri Dec 2 00:35:43 EST 2016

I was wondering if anybody had any thoughts or observations concerning this miner as I am a total newbie.




Your hard ware errors are a bit high on one board.  But not terrible.

Temps are decent fan speed is good.

I guess it is a 7.5 gh model.

Just keep an eye out on the hw 23 is okay but they can be 23 a week not 23 in an hour

I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Not necessarily.Quite often there will be a fair amount of HW errors within the 1st few hours but then hopefully things will settle down.

After 17.5 days of running my good R4b6 shows 326 HW errors -- and they are all on the 1st chain. 2nd board  -- 0 errors. On my bad one with a dead board, 356 errors in same time.

I've decided to screw the Warranty on it, I'll be doing some forensics on the dead board to maybe find wassup with it. Worse comes to worse it'll go out to BitmainWarranty in CO for Paid repair.

I think there are whole lot of different situations related to HW errors. The higher hashing board on my 8TH R4B3 always has 40-50 times of errors compared the other one. But the aggregate DiffA HW% is always < 0.001%.

At this very moment, system is up slightly more than 5 days, HW errors are 94 and 5167 and DiffA HW% 0.0006%. Temps are 8x/9x.

It seems a crapshoot on what kind of boards you get in your R4, as long they can be auto tuned to the miner's advertised hashrate. Not much consistency from what I see folks reporting on here.

The DC where my malfunctioning droid R4B4 has been sputtering along at half speed has started the RMA process along with various S9s they have there too. Nice failure rate on these units, hopefully this doesn't take too long...  Tongue

I sent my two R4's off last Tuesday, tracking indicates I should have them back tomorrow. I'm hoping for better luck this time around.

Are there any APW5 PSU "clones" being made in the USA? Less expensive?

I know where I can buy low-cost 7 connector PSU's but I was looking for something similar to the APW5 PSU due to it's
large fan/design. very quiet compared to other psu's

Had a strange issue with R4B2. Suddenly no shares were showing up on the pool...  Checked the gui when I got home and saw that all pools were alive but the last share sent was over 3 hours previously.  Weird, so I did a soft reboot and after the requisite time it spends restarting shares started showing up on the pool again.  This was after 56 days running, maybe hit another software bug when running for long periods and some register overflows or something.  Love that, keeps it interesting! /sarc

One of my returned R4's drop a board this afternoon, a quick restarted got it going again. It had been mining for just a touch over 7 days since it was returned. This makes me a little nervous.

That's really bad. My two R4 batch 2 (both repaired) are working without problem almost month now. Hashing constantly over 16TH together.

OK - now the hashboard shuts down within a couple of minutes of a reboot.

I wish I had never purchased these units.

Had a similar problem with my batch 4. It would randomly stop hashing. Sometimes in as little as an hour and another was almost 30 days. A simple reboot seems to solve the problem with mine also.

I have this random problem on one of the boards too. How's your temperature?

It's a little high around 93 chip temp, but that doesn't seem to be what causes it. The temp seems to be in the same range when it's running without incident. It's the autotune batch so there's not much I can do with the fan speed. It's in the garage where the ambient temp is around 40-50F, depending on the day. It'll go to Oregon mines when the outside temps start rising come summer.

My R4B1 didn't like cold air intake. Board temp was ok but one board just keep failing.
I planned to heat my crawl place under my house with it but can't because of cold air (5-10C ).
I move it into my house at higher ambient and this fixed my problem.

Below 20C , didn't run or badly. Higher ambient temp is ok. 

What's your intake temperature ?
