Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382

I will probably get the S1 upgrade kit instead Tongue

Let's guess the HR of overclocked S3, 520GH/s for me Roll Eyes

My guess is 575GH/s

..."BM1382 has achieved 15.75 Gh/s in hash performance, consuming less than 9.33 W on chip level at 0.75V"...

Let's do some math...:

9.33W / 0.75V = 12.44Amps ...per chip...

16 chips per blade * 12.5Amps = 200Amps per blade ...

NEEDS hell-of -a-POWER Section on the blades... Grin

I do NOT expect that BitMain will design S3 Power section with a lot of reserves...if any...

IMHO overclocking S3 will be a challenge...if possible at all...1-2-3% max...

Not even taking PSU in consideration...

My goal is pencil mod undervol underclock getting 450gh at 300 watts which is .667 watts a gh vs .78 watts a gh.

If this can be done they will be really quiet and truly good spaceheaters. I will put I in each room for the winter my house will be warm and toasty. And difficulty could be at 110 vs the current 13.4 and they would still be worth running.
