Title: X6500 FPGA won't mine???
Post by: mjester93 on March 07, 2013, 11:59:32 PM
Hey, I just recently acquired a X6500, in hoping to break even before the wave of ASICs come in. However, when I plug the FPGA up to my computer, I'm getting around 38mhash/s. What's going on???

What OS, and what mining software?

USB hub, or connected directly to a motherboard USB port?

How are you powering the x6500?

Have you tried a different USB port?

Have you tried rebooting?

Does the hashrate vary, or is it consistent?

Is the hashrate equal between the two FPGAs, or unequal?

What pool?

I'm using Windows 7 Ultimate 64, directly connected to motherboard usb port. The FPGA is using the circle power supply thing (12v). After reboot, I managed to get it up to around 50mhash/s, and it's consistent at that. Both of them are equal. I'm using the Modular Python Mining software on BTCGuild.

You're running the default bitstream (firmware) if you're running at 50Mh/s. 

You can select faster bitstreams at:
In the MPBM web interface: Workers > (select the board)
Then change the firmware file to /ztexmerge_200mhz.bit (or one of the slower fixed-speed bitstreams) or x6500-overclocker-0402.bit (variable clock speeds).

tml is also available for x6500 (should give you higher mh/s than mpbm):

ok, so I restarted my comp, and I now get the following error:

Maybe give BFGMiner (https://bitcointalk.org/index.php?topic=78192) a try.

Woooooo! BFGMiner got it working! Thank you, Luke!
