My batch 7 @ 625 MHz & 5.0 TH/s was delivered about 30 minutes ago. I've had it running about 15 minutes now. It had high HWE's when I first turned it on. Once I configured the pools the HWE's went down to 0.0027% and remains there now after 26 minutes of mining. My kernel log is blank like yours. I hope this fixes itself somehow fairly soon. I do have Tue Sep 15 16:50:19 CST 2015 Firmware. I'm about to update firmware. I'll edit soon to let you know what happened after firmware update to Oct. version. EDIT #1: Well, I'm a bit hesitant about upgrading firmware to October version because they do not have one for 625 MHz rigs posted for update. I'm concerned it would make the default frequency 600 MHz instead of leaving it at 625 MHz. Any opinions, anyone, about upgrading firmware for Batch 7 at 625 MHz default frequency?EDIT #2: I had a look at the kernel log on my other S7's that have the Oct. Firmware. Some of them have data in the kernel log and some do not. Interesting... I'm not going to update my Batch 7 to the latest firmware until they have a version posted for rigs with 625 MHz available. I do have my fans set on manual @ 80%. It's 75 degrees outside at the moment. So, the AC is on in the house right now. EDIT #3: I did a soft reboot on one of my earlier S7's with a blank kernel log. They are back to working and showing data in the kernel log. EDIT #4: I did a soft reboot on the new Batch 7 and the kernel log is fine. So, it sounds like you just need to do a soft reboot. EDIT #5: Don't be alarmed if your hash rate is around 1300 to 1700 GH/s after a soft reboot. This means only one board is hashing. Just soft reboot again and your hash rate should go back to normal and the kernel log still displays data. I had to soft reboot my Batch 5 twice because of the same issue with 1300 to 1700 GH/s after the first soft reboot.

there are only two machines: B1-5+B7 and B6, 8 the rest is just BMT slicing and dicing according to marketing/ machine performance. Same soft (9/15) on B7 proves it.
I agree about there being only two machines with varying frequencies as the default. I would say, keep 9/15+ manual at 75-80%-seems to be the most reliable combo. One of my B1 had an outage of 3hr (after intermittent internet) at hosting while on 75% manual; did not re-engage by itself (required a reboot) but did not burn itself either.
Thanks for the info. I feel more at ease about my rigs surviving an internet outage. I suppose I should raise those I have at 60% to at least 75%. My S7's have varied in terms of core temperature. Those I have presently at 60% were running too cool at 70 and 80 percent. Which resulted in a few GH/s slower hash rate. When I keep them between 50 and 60 Celsius, they seem to hash better with lower HW errors.

After seeing the temps of your boards in the rig, I would set it to whatever percentage keeps the RPM's where they are now. That may be at 80 to 85 percent. They mine better between 50 and 60 degrees Celsius. That's where it is now.

I received my batch 7's today. Fortunately they all arrived in great shape along with my PDU and I am expecting the rest of my shipments tomorrow from Finsky and Bitmain. BTW the PDU from Finsky is a nice product and everyone knows the 2880 power supplies and b/o boards built by Jabber are amazing. Thanks Finsky and Jabber, I have almost the entire mini-farm running on 2880s now. I am keeping several 2000BBs for backups along with the b/o boards from sidehack. His boards have the options I enjoy toying with. Load balancing anything is fun. I plan on picking up a couple of the ones Jabber built just because I like the options he threw on it with the LED displays since most of my setup uses whips over PDUs with remote capabilities. Nice wire is free through work scraps and I have a boatload of 10 ga sitting around. I cannot beat that. I also like making my own connectors. I guess it is a pride thing, knowing they are made the way I want them to be.
So, this is an S7 thread, and my S7s all batch 7s on this shipment are performing well. Hitting 5.02 ish on 3 and 5.07 ish on two others. All stock, and the same FW as previously mentioned from Sept 15. Temps and loads are higher across the board versus the batch 1 units. Temperatures are averaging 7 degrees higher on batch 7. Sitting right next to a batch 1 unit so no difference in ambient.
Loads are interesting with the batch 7 units at or all close to 1.10, 0.94, 0.91 Batch 1 I have clocked at 606 btw and average load 10ish lower.
Just throwing those out as the batch 7s have only been online 3 hours or so.
I have a 2880 for an S7 which is also running an S5+ single "module" with another 2880 running the other two of the S5+ modules.
I did upgrade the FW on the batch 1s, but I will wait on the Batch 7s.
I do not plan to purchase anymore S7s unless I am unable to find another miner. I would prefer to wait another month and see what else may hit the shelves, but I am also on a plan to replace everything higher than .44 efficiency (S5+).
The Avalon pricing did not float my boat once I learned the under-clocks were not comparable to the 4.1s, so I am in a holding pattern as of now but would still enjoy picking up a couple or three.
Bitmain's aggressive batches are setting the pace for the market. We desperately need some competition to make Bitmain work and not coast. If anyone wants me to check anything particular I am happy to do so. It seems many people received their batch 7s today.
I am jumping around several topics but one last item to mention is if you are using miners for heat consider a couple of fan types I am using. Inline fans can be used to push heat several ways but be safe pushing back in your hvac ductwork. Make sure you do not over-pressure anything and cause yourself leaks later on and also consider inwall fans for pushing heat from one room to another. Both can be had for very reasonable prices and if you set things up correctly you shouldn't even need to run your furnace / heat systems if you have just a few miners. I have zero noise complaints and keep the entire house warm. Any questions feel free to pop me a PM.
Do not support anyone or any company who isn't supporting the bitcoin ecosystem in a positive way. Pools who mine zero transaction blocks, or SPV mining taking a chance with forks to damage us all.
Final thoughts are keep on keeping on! It doesn't matter how big some company is, or how much they control, but for the simple reason we are what Bitcoin is about! That will not change until the last one of us little guys is gone and it is worth being in it!

Transaction fees go to the pools and the pools decide to pay them to the miners. Anything else, including off-chain solutions are stealing and not the way Bitcoin was intended to function. Make the block size set by the pool. Pool = miners and they get the choice.

With the massive difficulty increases lately, the last one was 10% and the next one looks like it may be close to 10% as well, how is anybody going to profit on these super expensive miners. I just don't see it. I mean I know the price increased a lot but if the difficulty increases at this rate it is not looking good for the new S7 buyers.

Good points Brob, but this isn't the first time or the worst. As you know it is a matter of numbers for some people and others it is the love of what we are doing here.
People are still profiting and some are doing so magnificently by buying 20 units and selling 5 for 20% more than what they paid. People also sell them after using them for 90 days or so.
Consider the meta game with mining and you can see what folks are doing with miners like the S5 and even still the SP20. They are holding their value well. There is a 2nd and 3rd owner market who can make magnifiecient profits when most of us cannot. For example the Venezuela guys have amazing power prices and will buy S3s even along with S5s and SP20s.
You can do it, and you can make money as the BTC price increases.
Factor in the fact that some people are able to eliminate $300 per month heating bills and you can begin to see numbers which make more sense. Personally I didn't run heat almost the complete last winter season and have prepared things so I will not need to do so this season unless I lose electricity.
Besides, for some of us it is more fun than almost anything else at the moment and seeing the ecosystem grow is a huge driving force.

Batch 5. Not too shabby. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FbHmGjTB.jpg&t=665&c=6Sycc6vjt1CJMA) do you need new firmware for the 625mhz? Yes, I just got my batch 7 in tonight and whatever firmware that is on there is amazing. Of course it is only going to work on batch 7 I am assuming (162 chip version) Let me know. Thanks!!
