Well after some tinkering last night I've found out my R1 will hash at 200 & 250m but only for a couple of minutes. The green led doesn't flash but I get accepted shares and it reads it on the ckpool app as 12ghs. I've got a fan on it but can't seem to get it to stay hashing. Anyone have any ideas? Wifi is disabled and suggested diff is set to 12.

@Glue: yes it´s a resitor and a capacitor covered by the glue and its connected to 53355´s  PIN 1 (you can see on my picture there is the print on the left site of glue, R31 (Resistor) and C29 (Capacitor)
Very strange is, that R40 (you can see it on top of R31) is missing on my PBC, but on yours it was connected before?

Another possibility is to trace the tracks and find a point to cut a track and just leave it all in place?
Yes, thats will be the next step, I think!

@pics: okay, no problem Smiley!
 I´ll do it this eve or tomorrow, when I´m back at home.

Andy after looking at your pictures I have a new theory on the Glue.  Smiley



You can see on this picture the same glue being used to hold the Light Pipes in place, which makes sense. I wonder if the blob on the zero ohm resistor was put there by mistake?

Where abouts do you put the  --suggest-diff 64 (is that how you enter it aswell?)?

Put it in the password field. Separate the password and the parameter with a blank:

--suggest-diff 22


Not to low?

Hi all,

ckpool has some problems. Some miners went offline or switched to failover pool.
Please don't forget to set it all back to ck, once the site's problems are gone...  Smiley
Ohh, yes, i recognized, that all my workers switched from de.ckpool.org to solo.ckpool.org  Sad .

But the solo.ckpool.org seems to work  Smiley.

ck has posted in the ckpool thread that DE provider is under DDOS attack.

R40 is a position for the resistor to ground on FB and is not fitted on either rev. I did not remove it only R31 the zero ohm resistor. This has been done so the the Vcore voltage is fed straight back to Pin 1 with no potential divider, this gives them the absolute minimum Vcore possible.

Rich
@R40: Ahh, okay!!!

Yes, thats the same Resistor  (R31!), covered by glue on my revision...
Btw: I´ll send you a PM with a link to a couple of R1 pictures, I made Smiley.

I´m not sure, what the reason for the glue is Huh, but believe me, it's not easy to take it off  Sad
Its very flat and really strong. I tried to remove it with a small screw driver, no way...
Than I tried it with some heat air (Air Rework-Station), but it´s seems to be "hard like stone", and I don´t want do damage the PCB.

@V1.9 PCB Revision: yes, I took a lot of pictures when I was disassembling and modify the R1 Smiley
You can get it of course Smiley!
Let me know how...
(I can put it for you in a zip-file for download if you want.. or can also make an upload to my image-hoster.)

@Heatsink: Yes, i bought it here: Silverbead Heatsink
(It´s an german reseller, but i think it´s also available in EU)

Interesting, seems a lot of trouble to go to just to cover up a zero ohm resistor? Can you see what is underneath the glue, does it look like a resistor? Must be something we are missing here?

Another possibility is to trace the tracks and find a point to cut a track and just leave it all in place? After cutting you could make a measurement to confirm it is still a zero ohn resistor?

Yes if you could put it in your image-hoster and PM me a link that would be great.

Hi Rich!

Thanks a lot for your answer!

That matches with my measurements!

Sorry for the Typo, my PCB is not 1.09!, it´s Revision 1.9) from 01/09/2016 Smiley

The problem is, that Bitmain (I guess, to prevent later modification by users!) puts a big hotglue ball on this resistor
(unfortunately its not so comfortable, like on your revision Smiley)
So its hard for me to remove it without damage the PCB  Embarrassed
Here you can see, how it looks :  Resistor Glue protect

Btw:
for BM1384 cooling I´ve used this heatsink on both sides.
It´s a little bit larger than the RPi heatsinks and works fine Smiley

But finally, good to know, that I´m on the right track, with the Vcore mod Smiley.
So i´ll try at weekend to remove the zero ohm resistor in any way...

Thx a lot for your help!

BR,
andY



I wonder why they have put on some Glue as I can't see many people taking these apart, and anyone that does is not going to be put off by a bit of glue? I would just try and prise it off, perhaps try warming it if it doesn't come off easily.

V1.9 looks like quite a big Rev, do you have a picture of the whole board to compare?

I like the heatsink, where did that come from?

Rich

Hi Rich,
maybe you can help me with that issue  Smiley:

I´m wondering, where do you connect the Pot for adjusting the core voltage?

In my point of view (after studying the TI TPS53355 datasheet), I tried to use the -> "VFB" connector (Pin 1) to adjust the VCore,
(between GND and Vout with a pre-resistor (like in the schematic link) but there is no change, Vcore doesn´t inc or dec, it´s constant
on 0.608V Sad.
I´m  working with a new release (V 1.09) of the R1 (there is something different (PCB layout, schmeatics) compared with the older ones.
It´s an error in reasoning  Huh?

Maybe you can help Smiley

Thx in advance ,
andY



Hi Andy am away from home so cannot look at the board to see exactly what I did, however just checking the picture of the board this is what I remember.



As you can see my board is V1.6 not sure if it's different from V1.09 which actually sounds older which is odd? You are on the right track but the reason why it did not work is because they have fitted a zero ohm resistor (R31) feeding back the Core Voltage to Pin 1 and they have not fitted the resistor to ground (R40) Because the feedback resistor is zero ohms a resistor to ground will have no effect. The reason they have done this is to get the absolute minimum Core voltage which I have measured at 0.61V.

I cannot remember exactly how I fitted the pot, however the zero ohm resistor will have to be removed. It looks like I have 3 wires going to the pot & a series resistor, so I suspect that one end of the pot is connected to ground via the series resistor, the wiper to pin 1 & the other end of the pot to Vout. At a guess the pot is 50K & the series resistor 15K but will confirm connections & valueson Sunday when I am back home.
