Title: [Speculation] Bitfury overclocking headroom with original regulator. Post by: Meizirkki on July 18, 2013, 03:15:19 PM The regulator on board is rated at 30A (https://bitcointalk.org/index.php?topic=250249.msg2666843#msg2666843).
If punin's blog (https://bittiraha.fi/content/se-el%C3%A4%C3%A4) (in finnish) is accurate, which we should highly doubt since they may have used external oscillator, the chips could do roughly 2Gh each without breaking regulators limits. This means 32Gh/s for a starter kit, yay :) and 512Gh/s for the 400 kit. I can't wait to receive (and likely break ::) )my starter kit.

Post by: alfabitcoin on July 18, 2013, 03:22:59 PM Can regulator could be replaced with 40A where will be able to run the 16 chip at 2,7Ghs?
Of course with heatsinks. Title: Re: [Speculation] Bitfury overclocking headroom with original regulator.

It might be difficult to find a pin compatible regulator. It appears, from a brief search, that this regulator series tops out at 30A. Regulator part number is TPS53355 Here's a post where Dave explains how to OC the board: https://bitcointalk.org/index.php?topic=251966.msg2745327#msg2745327 Title: Re: [Speculation] Bitfury overclocking headroom with original regulator.

Still, redesigning the board with smaller amount of the chips is a posibility. e.g. making 2 boards what uses 8 chips each.

The regulator's current limit is at 40A :D lets heatsink the regulator and see what happems
