Maybe a silly question, but are people still buying S7's? At this diff?
I am, ordered 8 x Batch 9. Price is reasonable especially at today's price of $1020.

Anyone have a chart to show the power at each frequency for the B8/B9 S7's? I'm wondering what frequency to downclock it to to get the closest to 1250w Max.

I have made measurements, You can find them in this topic. My early batch 8 takes 1210W with 700Mhz but don't get to advertized 4,73 Th/s, my other late batch 8 takes 200W juice and can go a lot higher freqs. Batch 9 is not shipped so power draw is unknown.

Is there any news on a more efficient Miner...S8?

Typically the even numbered models use the same chips as the previous odd numbered models so it probably wouldn't be more efficient, just more hashrate. If they introduce another higher hashrate with the same chips it will probably be an S7+ though. The next jump in efficiency should be an S9. Also just putting it out there but last night I lost internet for 10-15 minutes, didn't find out until this morning, and both of my S7's set to 60% manual fans did just fine. One is batch 5 with original firmware and one is batch 8 also with original firmware.

There may be a possibility of a higher chip count system running a lower average clock rate as an incremental efficiency increase...

im debating buying 3 B8 or B9.. difference in price is slowly dropping each day, but the 20th is almost here for B9
also.
has anyone had issues with connecting two units together with the slide rails? i connected a B7 with a B8 and for the life of me it will not slide apart now.. its like permanently stuck in the rail jammed up and wont slide either direction

Update: Got email from Bitmain/Sherry with tracking number for 2 x batch 5 replacement boards. +1 Got email in regards to batch 8 defective boards. +1 Should have happened a lot earlier, but at least we got some movement going in the right direction. thanks, Update: I too received an email notification of my 3 replacement blades on the way and got a UPS shipment notification of package on the way from China.

If the S7+ comes out and looks similar to an S5+, I would rather continue buying S7. The only way I would buy S7+ is if I could buy complete controllers and not just a BB Board without the Interface board for the fans and blades.

HOPEFULLY, your other RMA gets worked out soon. I think they may of had a lot of RMA's and it's taking a while to get to all of them. EDIT: Call them if you think you need to. I called them. EDIT #2: I use ooma [Voice over IP]. You can find it at ooma.com. It cost me 2.35 cents ($0.0235) per minute to talk to someone in China. My monthly bill is less than $4 each month. I prepay [or load up] my account for calling outside North America. All calls made in North America are free [Well, $4.00 each month]. You will have to pay for the ooma base up front then it's cheap from there on out. I bought mine used on eBay for cheaper than what you would pay on their website. Your choice though.

The S2 and S4.
Makes sense. S2 same chips as S1 but more of them to increase efficiency just a bit. Same with the S4 having more of the same chips than the S3 to increase power efficiency and hash rate. It's hard for me to imagine an S8 with same form factor as the S2 and S4 because they would need more than one PSU inside more than likely. However, I'm not saying they won't do it. It's hard to say what they will or will not do.

I agree and think we have seen the end of the even numbered Series. I think they have, for the moment, decided to standardise on a single form factor and for greater Hash in a single unit go for the 3 Bay S5+ style unit. A lot less development work and more common components. What form factor(s) they decide go for with BM1386 we will have to wait & see? Rich

Rich It is sad as I liked the even miners with PSU was really nice. But I would agree I think we not see a S8. S4's were one of my favorite miners I have had with nice build quality and LCD's. Also at end I did well on resell so I really liked them. I was lucky though and never had a PSU quit on mine. I predict we see another 3 bay again on future miners, it allows them to use same cases they are already getting made. And I think will still use the bitmain psu they are selling, adds to profit selling a psu ontop of miner. I'm not to sure when it will happen though. I think they will be on current gen for a while longer (I could be wrong though all speculation).

Agreed... Current generation is here for a while. At least until the block halving. It makes more sense as well to keep the present 3 blade closure. It would be nice if people had the option to simply have new blades shipped to them and swap out the blades for an upgrade. OR Simply buy new blades with controller and closure.

All my S7 fan speed is set to manual at 60%. Is there a reason why the speed is not at a steady speed? I have some that is showing 3700/4080 RPM and some showing 4040/4440 and 4040/4800! The 2 screetching ones are the ones that happens to be on the higher RPMs. Is FAN 1 the Intake FAN or EXHAUST fan?

I'm curious... Have a close look at the front and rear of the rigs to see if they are the exact same fan. They may actually be different. I have seen post in the past in this forum with different fans on rigs.
