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.

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
My R4 Batch-4 in my main farm at work is just as rugged looking as those s9's are. Hmm...

That graph looks more like the R4's are being logged on low difficulty shares and the S9's logging higher diff shares showing more variance. My R4's show similar spikes as my S7's & S9's.

I just received my 2nd R4 today and it is up and running - albeit a little hot!

My 1st R4 has temperature monitoring on two (2) chips, generally between the 70-mid 90 degree ranges.

This new R4 (my 2nd) only has one of its chips monitored, and is (so far) running around 110-115 degree range.

I guess my 1st concern is why is only one chip being monitored (both boards are at 100+% Th/s) and the 2nd concern, is 100 degree plus OK?

Update to the latest firmware release and you will get the monitoring for both chips and it will help bring your temps down a little.

Great - Thanks!

BTW - How do I see what the current release and/or firmware I have? The system/overview info for both R4s appear to be identical....Huh

Thanks again (sorry for the newbie questions)

System > Overview, look at the date after File System Version. That is actually the firmware version. For Bitmains downloads the date is given in YR-MO-DAY-24hr time format eg. 201612020035 is 2016 Dec 2 00:35 Eastern Time

I had a similar unit with one board reporting temps above 100 C. After 2 days the board stopped working. I hope you have better luck. Keep us updated.

Hot time, summer in the city, back of my mine getting hot & gritty!!!

Decided not to go the slow boat to China route, even though unit just a few days old, and just shipped my R4 with bad board to BitmainWarranty in Colorado for repair. I'm hoping for the best. We'll see what happens.

So my 1st R4 is:Fri Dec 2 00:35:59 EST 2016

2nd R4 is:Sat Nov 19 03:13:24 EST 2016

Is the 1st considered an "upgrade" to the firmware? 

I read somewhere here NOT to fool with firmware upgrades..but the unit is running hot..hotter than a few hours ago..in the mid 116F ish right now

Yes. As to *why* they are different and why your first one (as in bought first?) has newer firmware, who knows....

EDIT: Query -- which one runs hot? The Nov 19 or Dec 2 release? I ask because the R4 b6 that lost a hashboard (reports only 8 ASIC's) has the Dec 2 firmware and the remaining board runs around 100C.

The R4 b6 I got Monday has firmware dated Dec 9 and runs 3-5 C cooler.

There is no need to fear firmware upgrades as long as you confirm the firmware is for your device/batch/whatever before attempting to flash. I have flashed literally thousands of bitmain units without bricking a single controller.

Stop buying industrial miners, running them at home, and then complaining about the noise.

As soon as you open the ticket with Bitmain they will tell you to update the firmware. It did correct the overheating situation I had on my R4.  Also others have reported it bringing back boards that disapeared.  So you really need to to this update.

I am in the process of upgrading now.

One question - after I unzipped the R4 firmware from Antminer, there are 2 folders (c5 and xilinx) which contain 2 files, a bin file and the one i need to use (i believe) .. a file named "angstrom_rootfs.jffs2"

Both of these files are have the same date (12/2/2016) but have slightly different file-sizes.

The one in the c5 folder is 20,397 KB and the other one in the xilinx folder is 20,864 KB.

Which one do I use???

DO NOT UNZIP THE ARCHIVE.
Upgrade it with the zipped file.
Please follow the Antminer R4 manual found at www.bitmain.com

Upgraded of the firmware completed SUCCESSFULLY!

Both chis are being monitored, fan speed higher.

Temps are coming down, one still at 115F right now, other is down about 8 degrees so far..still low 100's but where it was.

No errors and hashing at capacity!

I'll keep a close eye on the temps ad let you know how it goes.

THANKS!!!!!!!

No they are not. They are pointed at CKpool which holds a very steady diff over any given time vs some pools like Antpool where I'd see several k difference in difficulty when checking several times over say an hour.

The R4 batch-4 at work (often >9THs) shows diff of 7.078k and the 2x R4 b6 at home read 6.473k for the good one (rated 8.7THs, near dead-on that speed) and 3.377k on the one with 1 bad board. Bitmain's software is doing something else to even out the hash rates on a very fine-grained scale.

Even my s7's show more variance than these 2x R' batch-6's do.

That's strange. I use kano (CKPool) as well and my worker shift graphs on the site show similar variance among all equipment I've looked at. If the software you're using is pulling the speed direct from the miner, that might explain it. The reported speeds in the antminer interface can vary quite a bit from actual pool-side speeds.

Indeed, that eerily smooth graph data contradicts the variance that inevitably must be there...!   Shocked
Something fishy, thoughts?

The graph is from Awesome Miner showing hashrate over 1hr. Highly recommend it!
Anywho the sampling rate is every minute and yes is read directly from the miner via the API so it is true throughput.

Now, as I recall, part of the 'Majik' in BTC software is that along with input from the pools the firmware/software in the miner itself sets the diff of work sent to each hashboard or ASIC. To me it looks like Bitmain is tweaking that internal diff on-the-fly more often and probably per-chip... Seems like a good way to throttle speeds. Given that they are using a top-end Xilinx processor the controller certainly has the horsepower to do it...

so far i am in possession of 7.5, 8, and 8.7 models. I noticed that batch 6 - 8.7 model runs significantly hotter than the other two. Specifically ranging 87 - 112 deg in readings in the same environment. I know it runs at higher Hz but this makes me concern its lifespan. anyone can echo on this?

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.
