Title: BUTTERFLY 832 UNITS
Post by: lightlord on May 29, 2012, 09:08:09 AM
Hello I have a question regarding the BFL singles. I already got mine, which mines at 832 about.
Can it be overclocked? I heard of the firm wares up to 890 something, but could someone
add cooling to these devices and overclock them further to like 1000 Mhash?
Because I like to try it out, but I wish someone would write a over clocking utility for this.
So I can just slide the bar up and down and tweak the voltage and things.

I was thinking of adding water cooling, manually opening this up, and hooking it up.
But I want to know if its possible to over clock it to 1000 or so.

Thanks for any help I get.

You can change the firmware with another version, see https://bitcointalk.org/index.php?topic=80497.0

already saw that, but it doesn't go to that high.

We will release faster firmwares in a short while.

Release a nice overclocking program if possible, with voltage dials/over clocking dials.
Over time the voltage on parts can be dropped, like my CPU for example after an year of running
it was able to drop to 1.1875 volts from 1.45, But when it was new it crashed at 1.35, so over time
it will be able to under-volt more.


And really since it throttles isn't it the best to flash it with a 1000 Mhash one, and it Auto-throttles to the right area,
so in a -10 Celsuis day with my fan blowing onto this it would be able to go to 1000 Mhash with auto-overclocking,
But at the summer it will auto clock to 760 or so.


Really why not just create a driver that Overclocks the device into it hits 50 degrees auto.
Its the temperature that is the problem normally in overclocking. This would add extreme convenience,
If I add a water block or something, it would go up to 1100 Mhash on its own to yield the 50 degrees,
why not do that? Reasons?

And what if 1Ghs firmware kills the FPGA, will you complain and send it back for replacement, or take the loss like a man ?

Reasons?
No remote voltage control... That needs hardware change.

Overclocks the device into it hits 50 degrees auto. (This would guarantee it from not over-heating, it would keep at 50 degrees,
Don't see how it would kill it
)

It won't die, unless you touch the voltage. A lot of units can such as video cards over clock a ton before voltage increase is needed.
I never had a over clocking component die.

Overclocking only kills it if it over-heats. People have taken CPUS up to 7 GHZ but it was with liquid nitrogen, it didn't die.

Great, waiting for faster firmwares.
892 is running perfectly.

Today I transferred my Single to a spot where it's currently about 10°C (50°F), and it's running like clockwork >880 MHash/sec. Faster firmware please!

What are you guys running for miners? I've been using Ufasoft but the statistic reporting stinks and I'm not sure the performance is ideal.

Post your miner and any relevant parameters if you can.

Thanks,
Andrew


EDIT: should i just start a new thread for this?

I'd just go with CGMiner.
