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)

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 ....

Code:
You know what ? This super AC products are no sh!t better than the "white sillicon s#$%t". High error rates at 200 MHz indicate a problem with heatsink placement. It's not about bad thermal grease !
I spoke with friend witch used AS5 and has this same problem as me with ~200Mhz "problem"
Whats the sollution to this ?? I`m thinking about 2 things - spirit II on scruwa, "stock" cooler on scruw and 2 just on stock. We will se what happens. I`ll use "somme serius s#$@t" as a thermal grase
and hell yeah - !! 
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 ??

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 ?
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

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 ?

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 !
April 28, 2012, 08:32:59 AM
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
is a good mistery

or better cooling, my single went up from 204 to 220 with artic mx-2 under the cooler
I doubt that this is the secret why I get high hash rates.
In my case I have been using Arctic MX-4 thermal compound for my initial installation of the heatsinks on both of my quad boards. See my post on April 24 with picture. Pay special attention how my quad #2 (on the right) does 901 MH/s and which heatsinks I am using.
In the meantime I changed my #2 to stock heatsinks (Xilence/Deep Cool) and used the heatsink compound that came with the coolers. And today, in my previous post, the hashrate on #2 was still 901.1 MH/s. Conclusion: no difference if Arctic MX-4 or the one included in the small bag with the stock heat sinks (at least in my case). Maybe in your case the cooler just didn't sit right (air bubbles?).

i`m wodnring with waterblock put on it 
i should have 2 or 3 NB waterblocks... still need one or 2 :|
I have lost AS5 and used somme simmilar shit, witch brought me f=196-208
Is it ok to put on it thermapad 0.5mm 7W/mK ??
any sollution to cool VRM section ?

I think, this could be the reason. The thermal compound and/or the way how you apply it.
I've used Arctic Silver 5. And later today I will post some photos of "how" I apply it.

I am using the same FPGA. The passive components are different, but this surely can't be the reason why.
I guess you've got a better charge of Spartan6 Devices. Same Speedgrad labeled but inside better. April 27, 2012, 04:55:58 PM

I know this is very far fetched, and it's just a theory, but I am at sea level (actually I am sitting in the 43rd floor right now with my quads buzzing away next to me). At higher altitudes, the air density, fan efficiencies, and heat transfer efficiencies all decrease. I read somewhere that a ballpark figure is 3% for 1000 feet (300 meters). So you guys in the alps are definitely at a disadvantage. The good news is that the new home for my cluster is on the 3rd floor so I should get even higher numbers
Send me one of your boards and I will put it right next to mine in order to confirm this theory.
The quads have been running for 8 days straight now:
#1. 915.3 MH/s
#2: 901.1 MH/s
Ambient temperature around 25C right now, no air conditioning, relative humidity at 84% though :/

2 Quads up and running in cluster mode. Unfortunately I don't see these "high" freqs 
Those that order in large numbers get the slow boards
Not sure if Alex is using the same chips for his license boards. Perhaps he has SG3 spartans ?

Any recommendations for USB hub? Need to connect 25 FPGAs.
+1
Some tips about powering them are also welcome. That ATX Psu way seems little tricky. I think it would be easier to just get those 36€ PSUs from ztex.
I will go with an ATX PSU. I'm planning with a Crossair 1200 Gold and PCIe-8 extensions. 2 PCIe-8 will power 5 Quads (2xGND 1x12V per Quad).
April 27, 2012, 11:19:09 AM
Just arrived. The brandnew ZTEX Quad's
... and a 3,5 inch harddisk for size comparison.
SUPER fast shipping. Thanks ztex.
Wow. Ordered one yesterday.
April 27, 2012, 10:53:28 AM
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?
