Well, it's my turn to have a dead board on a S9. Batch 10 running for 3 weeks, center board shows OXXXX.

I wrote to BitmainWarranty since its closer to my location. Is it better to send it to Bitmain in China? I'm from Canada.

Thanks!

Broken link so maybe they already sold all their miners.

Hi guys, Ive purchased some S9s from Bitmain but I want more units. Is there a legit shop to purchase some, in USA or Canada?

Thanks!

Received a B16 last friday. Hashing good and normal temps with 1 fan at 80%. Less noise than all my older S7s.

Got antivirus threat removal when mining with this client.

I'm using IBM 2880W server psus with 2x S7s per psu. Voltage is uber stable. Effiency is better with 1x S7 but it's not a big difference.

Still for sale!

Yes but with the new fans I installed it's not the same sound anymore.

dB level I don't know. It's way less than original fans (which make a mega high-pitch supersonic turbojet crazy headbang-into-the-wall noise) but I don't really care about dB, all my miners fans are running almost full speed.

The PSU is internal and working on a 90-264V range. Currently 240V.

The shipping is at your expense, but if you're selling your S7, we can exchange miners + BTC from me and I pay shipping for both.

Try to overvolt it without overclock it. Your error rate should get lower.

philipma1957, thank you for your reply. Is your B2 still running at high frequency? For how long?

I only have B8+ S7s. Fans at 80% running 4300rpms, and 60-65C temps.

Hello guys,

Is there any of you that are running OC'd S7? I know that some tests have been done on short term, but is there someone who successfully tested it on the long term?

My S7s are already running on 12.7V but at stock frequency. I want to overclock my oldest one to see where it can go, calculate the efficiency at the wall at different frequencies, and let it work as long as it can at high frenquency. Ambient temp is less than 20C in the warehouse and my test miner have 0.0000% error rate, amazing.

 

All SP20s are sold! 1x SP10 remaining.

New price drop! Must go!

Back on track!
