@burnin... I now read that avalon miner were successfully overclocked to 395, stable at 375MH/s or so. From 282MH normal. Now BKKCoins thinks about how to change the layout of the board to meet the higher power supply needed.
Are the bitburner already ready for those high overclocking or would there a change needed because its otherwise not possible. I know overclocking is planned but i believe bkkcoins already had planned it too even though now he needs to revise his board.

My design is able to provide more current to the chips then bkkcoins (2.5A vs 2A per chip).
Therefore i don't see reasons to increase that even more.

Overall Project status:
Done some more work on the Firmware, it now works flawlessly with cgminer.

The Prototype will not arrive until mid week due to problems with my manufacturing partner for the protype.


was wondering how long it'd take people to notice ( and more importantly share the constant that we've released on github.)

the number you are all aiming for is 450 Tongue of course, that's not really possible on just air cooling.

What a tease BitSyncom is, lol.  I would love love love a unit at that kind of hash, but would the unit need to be submerged in oil perhaps?  Can't imagine even water cooling would be of much use at that output.

On the side, I wonder how long they had that chip stable at 450 for before it went supernova

450Mhz? really? 2.5Amps can't be enough for that, In sight of that I've bumped up the specs for the regulator to 60Amps total. (3Amps per chip)
With different inductors i could push it to 80Amps total.  (That would be scary 100Watts per module Shocked )


Hey just a little question.

I have 2x 10 chips from differerent groupbuys and I want to order a 20module, there should be only a few days difference between.
Can you just store the first 10 chips to the time the other 10 arrive?

I wait until all chips needed for an order are present.
If you want per batch shipping do separate orders for each batch.
