Actually
This is working on Avalon 2
case 356:
buf[6] = 0xf3;
buf[7] = 0x0a;
break;

I don't create firmware, I write the software and build binaries which I load directly. However, I have committed the code supporting the higher speeds to the git master tree for cgminer and xiangfu will create new test firmware shortly supporting the new speeds. Mine has been stable at 350 now for a few hours, averaging ~82GH.

Question: what should be buf[6] and buf[7] for 325MHz, 350MHz, and 375MHz?
if (frequency == 256) {
buf[6] = 0x03;
buf[7] = 0x08;
} else if (frequency == 270) {
buf[6] = 0x73;
buf[7] = 0x08;
} else if (frequency == 282) {
buf[6] = 0xd3;
buf[7] = 0x08;
} else if (frequency == 300) {
buf[6] = 0x63;
buf[7] = 0x09;
}
Use these at your own risk! For 325 MHz: buf[6] = 0x2b and buf[7] = 0x0a For 350 MHz: buf[6] = 0xf3 and buf[7] = 0x0a For 375 MHz: buf[6] = 0xbb and buf[7] = 0x0b The meaning of these values is documented on page 6 of the Avalon ASIC (A3256-Q48) datasheet. Thanks, I guess I need to take a good look at the datasheet first, and then re-compile cgminer with the new avalon driver. |

I am not sure, just plain assumption. There is possibly a clock divider and clock multiplier values associated with those registers, and it would be good it reverse engineer it, to check if higher than 300MHz performance is feasible. |

somebody recompilation avalon drivers and run avalon Frequency 332Mh,it's hash ability about 80G.

Since that the auction is for 2 units, it would be important that you specific into how much you are interested into. This also because maybe one unit will be sold for a lower price than the other.
BTC133 for one, BTC110 for second the highest bid per unit is 132.5 includin fee's...... The way I see it the highest bid is 133 for one and 132.5 for another |
