x6500 on bfgminer 3.10.0

[156216]

I am running an x6500 with bfgminer 3.10.0 with bitstream "fpgaminer_x6500-overclocker-0402.bit".

Is there a way to lock the clock rate of the processors? They continue to increase by 2Mhz a minute until it bfgminer hangs with hundreds of HW errors.

When I start bfgminer, I select [M]anage devices, then [C]lock speed, 200 [Enter], then do the same for the other processor of the FPGA.

Any help would be greatly appreciated!
