I believe I'm doing what you are doing to inspect the rigs from now on with future batches. Especially, after reading the WARNING here in the photo you provided. Thanks for sharing... Interesting for sure. I like that they gave customer permission to open it and check. That is much better then the don't touch policy. Maybe they are changing for the better on warranty... or maybe to many were falling off. Makes me wonder on number for them to send that letter with it.

I wonder if I should make better wires for the batch 7 miner, I have 4mm2 wires about 40cm/16" coming from DPS-600s and PCI-e connectors with 4" thin wires soldered to cut off cheapo molex to PCI-e wires? Voltage is 12.14V at miner end running and 12.5V without load.

I wish they'd just outright say "Too bad, it's late, you're SOL. Thank you for your business." instead of making promises they know they won't keep.

Yup. Typical Chinese customer service... Lol
I don't think we're getting anything back. What pisses me off more is they have the $150 coupons away in a heartbeat a week or two ago to that other batch......

No problem with gripes about lack of compensation. No problem with that at all. However, "ethnicity" has nothing to do with one's "character." So, please refrain from using the word "Chinese" as though all "Chinese" have no "character." I know "Chinese" individuals personally who are good people with tons of honor and character. In fact, I know Chinese who have more honor and character than many westerners. EDIT: As for compensation; I'm going to be patient and give it a bit more time to see what happens. Yes, go ahead and tell me, "Don't hold your breath." That won't keep me from having patience. Let's see if Bitmain will have honor and character regarding their "word" about compensation. They did not say "when" there will be compensation. I'm just going to remain patient and see what happens.

I am using the Bitmain PSU. Will measure voltage and power soon.
Still waiting for your measurements...

Makes me wonder on number for them to send that letter with it. dont touch to my ass i removed cleaned polished inspected and resoldered... Note: i am serious, dont try this @ home also i am thinking what is 1385+BIN2 label on v2.0 boards. 1385Gh binary v2 if chips have any eeprom we fucked up folks. this means hash count is true. if 1385 not hash number or freq, meaning bm1385, so why labeled 1385 ? all S7's have not bm1385 ??

I like your style... If you take delivery of a Batch 6 or 8 please can you take a picture of that side of the board so that we can see if there is a Buck Converter chip? Rich

Rich i think you are right , new boards with coils have a buck converter, because i seen ICSP like 6 pin socket on bitmains picture. this means have a microchip pic for voltage controller like s4. another side of pcb must to have 2 or 4 big mosfet + buck controller ic + microchip pic. edited old msg: also i am thinking what is 1385+BIN2 label on v2.0 boards. Huh 1385Gh binary v2 Huh if chips have any eeprom we fucked up folks. this means hash count is true. if 1385 not hash number or freq, meaning bm1385, so why labeled 1385 ? all S7's have not bm1385 ?? or maybe this is not bm1385, this is different new chip bm1385+ pffffffffffffffff

On the 1385+BIN2 that could imply that they are speed / voltage selecting the BM1385 chips and these were from Bin 2? Final observation from a much better picture of the chip side of the board is that they have fitted an oscillator to every node on the Board. The S5 originally had a single oscillator, then on the V1.91 they fitted an oscillator for every 4 Nodes on the board (I still suspect this is one of the changes that enabled the S5 to be successfully undervolted), however the board layout actually had provision for an oscillator on every node. It would be great if the 135 chip boards turn out to have a programmable voltage Buck Controller... Rich

Rich i seen bin2 from this picture : https://ip.bitcointalk.org/?u=http%3A%2F%2Fi.imgur.com%2FkrFSsnV.jpg&t=559&c=Dovh_zqjP3lwJwbm1384 chips voltages at own corners, bm1385 feeding left and right, my picture is 4.86 S7 (i dont know which batch is probably B3) but boards version is 1.8 pcb version is 1.6 if voltage controller be in new boards. i think we can not control them because pic12f1822 job is simple; adjust voltage at boot and set working voltage to buck controller ic. this is chip protection for them.

Considering I've spent quite a bit of time in Asia and China in particular, I can openly repeat what I said above and give the middle finger to political correctness. It is TYPICAL customer service over there to treat ppl like they are. Seen it tons of times and had it happen to me enough to know. I already wrote off any compensation from them but still gives us the right to grips and tell everyone we know. Lolol.
