I've tried that too. The java window just pops up and disappears.

I've also got the problem with the mining options being greyed out.

BFL: Do you have any guess as what the issue is? I have Windows 7 Home Premium.

So i can't get easyminer to work because the mining options are greyed out. Ufasoft runs for a split second and disappears. I cant seem to get Cgminer to detect the fpgas.

Can someone please post a working cgminer config script? I can add the com port and the pool in the text, i just can't figure the overall scan and enable portion of the config file.

Thanks

Nope, only the one listed in Device Manager

->Ports (COM & LPT)
  -> USB Serial Port (COM3)

Nope still the same problem, I've tried the various compatibility modes as well, still no luck.  Also, tried it on a windowsXP VM i had here (VirtualBox) and get the samet thing!

No arguments from my side about window (especially vista) sucking, so that begs the question, where's the linux based firmware updater?? I don't want to use your easyminer software to mine, i just want to flash the singles then put them back on my Linux machines.

Hi, I have my BFL's up and running but wanted to flash them.. the only windows machine I have here is running VISTA (my normal mining is all on Linux), so i grabbed the EasyMiner_V_1.1_Beta to see if I could flash one with the higher firmware, but cant get it to run.... my device manager shows the one BFL Single i plugged in properly on COM3 (well COM3 appeared when i plug it in), but when I open EasyMiner, (the only option available is "administrative mode") and click "Proceed", I get the windows dialog "BitFORCE-Miner has stopped working  A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available"

Any idea how to fix this?

Just unpacked the singles - 1 of 6 sounds like the heatsink is loose -- rattles horribly.

Also - 1 of the singles shows loaded with the 816 firmware?!?

Anyone else get a single that DIDN'T come from the factory with 832 firmware?

I noticed this also. If this heatpipe is really custom made the job wasn't done good.

I'm thinking about putting a metal plate between the FPGA's and the heatpipe. This metal plate should cover the full area of both FPGA's and transfer it to the heatpipe. Maybe this could improve the cooling which is obviously mainly limited by the only parted covered FPGA.

Has someone already done this?

Are there 2 different diodes, one for each header? Or just one that covers both of them?
Also, if the barrel jack was replaced with something else, would the board itself support that current draw without issues? I'm guessing the warranty would be void in this case.

Thanks for the info Their CFM rating is lower than the stock Single one. I am thinking if one is going to put these somewhere far away a higher CFM fan would be better. I found 68 CFM fans with a noise signature of 43 dBA which is a tad bit higher than the stock Rev 3 fan (32).

The question is can the fan header on the Single handle the extra current draw. Is the cooling performance noticeably improved going from 45 CFM to 68 CFM.

I've flashed them a number of times, with a couple bad flashes too (something interrupted it halfway through).

Here are how they look after mining for two days:



I'll probably be taking them down tomorrow to check the thermal paste.

Update:

I tried flashing the 792 & 800 firmware & the unit still throttles (room temp 76 degrees f) & won't get over 300 mh/s.

However with the 768 firmware I can mine with room temps of up to 84 degress f @ 760 mh/s,I opened my windows just to see if the higher temps would make it throttle & no throttleing.

Next step is to turn down the A/C to 70 degrees f & keep flashing firmware,higher each time & see what happens.


Before I do,is there any limit to flashing?? I already flashed 4 times so far............don't think so,but its better to ask


Also,if after all this & I still can't run anything but the 768 FW,I may try reapplying the H/S compound.Those that have done this,what compound are you using??

I always use Ceramique on CPU's & GPU's,but it's pretty thick stuff & I'm thinking it may be too thick for this application.

I've been keeping up with rkozola's issues to maybe be enlightened as my problem is similiar.

BTW,I know USB 2.0 works,but is there anything to gain with using USB 3.0 ??

Is overheating of either/both of the two fpga's the only thing that can cause throttling?  Or are there other factors that can cause a single to throttle?  I removed the heat pipe, the old paste was uniformily spread on both chips, cleaned up the old and reapplied some new stuff making sure it too was uniformily spread.  So far the highest I can go is with the 808 firmware and that might throttle a handful of times an hour.  Temperatures consistantly reported between 44-46C.  Any firmware above with throttle every 3-4 minutes.  The only thing that I forgot to check for was that both chips are sitting in the same plane, but by looking at the even distribution of the thermal paste, I would guess they are.

Also, as an FYI in case the front led stops working for any one else (or falls out like mine), the two leds on the right side will go out for about 12 seconds if the unit throttles.  Although, I did go out on a limb and was able to reattach the led that fell off.

Well,I flashed the 768 firmware & viola,it's mining @ 750mh/s

I expected a learning curve,so I'm not disappointed in the issues I've run into  

It's a great little device & I'm very pleased with it.I'll be getting more soon!!!

Hope you guy's at BFL can get these to work a little better in a hotter enviroment,like 80 degrees.I'm in florida & to get to 72 degrees is very costly.

Thanks again for all the help guys !!!!!

Thanks for responding BFL

The light only seemed to flash for reject shares or in between work.

Ok,I flashed the 824 firmware & ran a diag :



My room temp is 78 f.

That flash dropped the hashrate to 125. Now it doesen't flash at all

EDIT: Duh...again........I didn't restart it

Thanks !!!!!!! That did it 

I was sooo tired after doing a landscape job yesterday,I must not have been thinking right

I made about 10 .bat files & none of them worked,I was mislabeling them,duh

My hashrate is half though any thoughts??



Maybe I flashed the wrong firmware version,I DL'ed the 832 version & flashed it instead of a higher one just in case of throttling like I had read about.

Is the temp correct in CGminer??

Room is temperature controlled and sits between 68-70F (20-22C).  There is nothing exhausting hot air and the singles sit about 8 inches apart and should be well vemtilated.  I have tried power supply, usb cables, host ports from working units and no change in operation.

I had a box of 3 and a box of 2, just wondering if both units I have issues with were from the box of two.  At least from appearance, no damage to either packaging.

I have tried the 832 and 800 firmware, both exhibit the same behavior in cgminer (after a minute or so, stuck at 600 +- 100).  I did a Light Diagnostic in easyminer at 832, Throttled 22 time before reaching 100 in about 600 seconds.

All the square heatsinks appear firmly in place as well as the small heatsink/fan on the botton, I don't want to put any pressure to them.  The main heatpipe had both clips seated correctly and I can see white thermal paste along the edges of the chips.  It also appears flat and not out of place.  Verified the top and bottom fans are both operational.  Top fan seems to be pushing the same as the other units, tested by checking deflection of a piece of paper over top vent.  I tried putting a powered 80mm fan on the button pushing into the unit, still problematic.

I have the ability as well as the usual white thermal paste.  But I will save removing the heat pipe, cleaning and reapplying as a last resort.

edit 1)  I am now trying the 768 firmware to see what happens, figure 768 is better than 600 or below.

At one point it did light up, although it was dimmer when compared to the others.  The only thing I did was move it to another computer.  I was trying to figure out why it was getting low performance.

After 8 hours of runtime

tried the unit on a power supply from one that is working well, started mining and after about a minute it just stay between 500-700mh/s with temps at 45-46c.  Ran the light diagnostic and after getting to 100 had 22 Throttles in about 600 seconds run time.  Hard to tell if it is throttling since the led fell out.

I was amazed that I got a calling so quickly on a Friday evening after the email about the first one.  So at least it looks like they are standing behind their product, just hope I end up satisfied with the issues relating to the first and now the second problem I have had.
