Are you using 220v as your supply source, Anti?

If it's not cooling, I'd suspect just really clean power being supplied to the units.

Otherwise it would have to be some slight difference in the design his are on or the chips.


Yes, is one possible solution...
Or a particular lot of spartan6

used this white sillicon s#$%t given to you with those "stock" cooling ??

i just have found my Thermalright spirit II and i wont to test it insted on of the "stock".
hav fpga deals with cold ??

You know what ? This super AC products are no sh!t better than the "white sillicon s#$%t". High error rates at 200 MHz indicate a problem with heatsink placement. It's not about bad thermal grease !

hi,

can i have some values in mh/s about ztex 1.15x ?
what the highest rate that have reached with the single board of ztex ?

hi,

can i have some values in mh/s about ztex 1.15x ?
what the highest rate that have reached with the single board of ztex ?

Here is a list from some of CA Coins boards

My fastest is (was) 220 MHz but not at 24 degree C.

I spoke with friend witch used AS5 and has this same problem as me with ~200Mhz "problem"

Whats the sollution to this ?? I`m thinking about 2 things - spirit II on scruwa, "stock" cooler on scruw and 2 just on stock. We will se what happens. I`ll use "somme serius s#$@t" as a thermal grase Cheesy and hell yeah - !! Tongue
Edit:
Spirit II has broken heat-pipe...it will be just stock on screws.

EDIT2:
1&2 are on screws, but 3&4 on stock, 1-208, 2,3,4-196 aggain, ambient 34*C !! 2,6 KW taken from the wall in small room....

Can I leave it mining for a long time ??

Nope i can't hook up more than 9 FPGAs to my Mac with that usb hub (TRUST 7 Port Powered USB Hub: Connected to my MAc mini, doesn't matter witch port). Even if its powered separately..... The 10th FPGA gets CRC errors for the Bitstream.

€: its the new single i bought with the quad..... It thinks to be a 1.15y somehow ?
PIC:


what the heck did i do here ? How did this happen?

Defnetly need some help over here..... Im totally unable to tell how that could happen but the one Single (the new one i got with my quad) believes to be a quad to..... Closed JP one and tried to erase the eeprom and that didn't work.....?

has anyone had similar experiences with new singles?

One of my older singles seems to be dead for no reason ..... It won't be recognized buy the mac (or any other PC i have in my household). It's listed as an unknown device under the Hardware Manager (Widows 7) and as i try to install the Ztex driver for this i always get the error: "There is no Driver ....blah blah blah".


€: The new Single
I can however program it with an old bitstream from 120221...jar an it'll mine right away. Somehow that isnt persitent and when i use the new jar it still belives to be a quad...


Seems to me that this board was factory programed like this?

Ill try some different thing tomorow at my pc ....

I my experience you have to bridge JP1 when you turn on the board, but once it is started you have to remove the jumper again. Then program the firmware in programming mode.

(I programmed the d firmware instead of the y firmware into the quad by mistake on my very first test run)

I guess I've found the problem.

This is the of the worst Quad I have.

Code:
002-0: ztex_ufm1_15y1-04A3476278-1: f=200.00MHz,  errorRate=0.87%,  maxErrorRate=1.00%,  hashRate=198.3MH/s,  submitted 14 new nonces,  luckFactor=0.82
002-0: ztex_ufm1_15y1-04A3476278-2: f=196.00MHz,  errorRate=0.23%,  maxErrorRate=0.55%,  hashRate=195.5MH/s,  submitted 16 new nonces,  luckFactor=0.88
002-0: ztex_ufm1_15y1-04A3476278-3: f=196.00MHz,  errorRate=0.00%,  maxErrorRate=0.81%,  hashRate=196.0MH/s,  submitted 13 new nonces,  luckFactor=0.83
002-0: ztex_ufm1_15y1-04A3476278-4: f=192.00MHz,  errorRate=0.11%,  maxErrorRate=0.50%,  hashRate=191.8MH/s,  submitted 10 new nonces,  luckFactor=0.95


So I removed the heatsink of FPGA-4, because it's the one with the lowest frequency.

Here are the photos of the heatsink and the fpga:



Can you see it? The heatsink touches the chip only at the corners  Shocked

This could be the heatsink or the chip. One of both is bent and not flat!!!

Did you use the thermal pad that came with the heatsink? Maybe this is the issue here.

Now a test to prove my theory.

I've applied some new AS5 and scrachted it linear very slightly. Then I've put the heatsink and moved it around a little bit. With the same result: the heatsink touches only at the corners. Here are the photos:




What can I do???

No. Do I have to use the pad and thermal compond???

BTW... one board run super and I've applied the heatsinks and AS5 in the same way.

Code:

I never used the pad myself either. When Ztex shipped the fpga there was warning, that using the pad isn't recommended.

Maybe an experienced forum member here knows advise :/

What do you think about these Liquid Metals Pads (http://www.coollaboratory.com/de/produkte/liquid-metalpad/)?

Do they work with the plastic case of the fpga?

Will the fpga reach the burnin temprature (>58 celsius)?

Now a test to prove my theory.

I've applied some new AS5 and scrachted it linear very slightly. Then I've put the heatsink and moved it around a little bit. With the same result: the heatsink touches only at the corners. Here are the photos:

What can I do???

That's why I usually prefer the "blob in the middle, then put on heatsink and move it around a bit" method.

The die will certainly reach that temperature, however not the case if it is cooled properly.
The "bad" thermal connection before that burn in happens is probably sufficient to keep it from going up that far.

AT YOUR OWN RISK: Your best bet might be to put the board into a precisely temperature controlled oven at ~80°C for a couple of hours.

No. Do I have to use the pad and thermal compond???


No, you should put about the amount of a tip of a match on to the chip, then spread it evenly. Then put the heatsink on top and attach it using the metal parts and nylon fasteners to the board. Move it around a bit and you're set.

[EDIT] Sorry I noticed you tried this allready. I would say your heatsink is not 100% flat. Try using little extra AS5, put it in the middle, don't spread, press heatsink on and clip it in, then move and twist it a bit to get a better spread.

no that'll kill your board!


My new single works with the old bitstream but not with the new ....

try also this:




i use pad to contact the pcb to avoid to scratch and of course some grease.

the board runs 220MH/s@220MHz stable.

the second fan is necessary to transport the heat away.
the second heat sink can be smaller but i have only this at the moment. so i was taking this.

One of my older singles seems to be dead for no reason ..... It won't be recognized buy the mac (or any other PC i have in my household). It's listed as an unknown device under the Hardware Manager (Widows 7) and as i try to install the Ztex driver for this i always get the error: "There is no Driver ....blah blah blah".

I know this problem. Try to plug it in and out repeatedly. If that does not work, shut down the computer and disconnect all devices. Start the computer and reconnect the boards one by one. My advice is to not remove them once connected and running.
