No problem  But i am not sure about their setting. The cgminer only show 8/256 At 0:47, watch in 720p full screen, and you can see SYS_CLOCK=830MHz But 17A/204W is awesome. I'll be happy with that! That's close to 1GH/W And i touch the heatsink, it's only warm with 4900 fan 830MHz mean around 212 on our setting |

Yeah I want to run this with less volts like they do 850mV should make it 200GH/200W so I get less heat and can put quieter fans on. But I think Zich said he got like 23% error rate!  If I swap with someone with a later batch Feb/Mar will they be more efficient or the same? Some test result  With 220 & 880mV, ampere usage on 12V rail is 20A  Then 200 & 870mV, ampere usage on 12V rail is 17 A. hardware error is very low  |

Sorry about that Gator.
Specially for customers like you we are finishing now 4 chip version with normal heat sink and fans.
I hope it will be stable @ 130 range with nice 2-3w fans.
The damn chip is sooo power hungry
Update in Monday
This is great  I am sure many people will choose 4 chip version |

Nice pictures guy's Congrats to all Spacial thanks to Zih for bringing light to power consumption! Have fun and happy nonstop mining Thanks loshia Tomorrow i will move to 260 & i will post the power usage |

I'll have to go hunting for a PSU tomorrow, can anyone confirm 850mV it runs < 264W?
I was trying with frequency 200 & voltage 850 mV but the board not hashing just like stifla first screen shot Then frequency 240 & voltage 850 mV , hardware error 23% |

Here some picture of my board that just arrived And fan picture, i bet Gator-hex will be surprises Bottom fan is "SUPER FAN" SUNON PMD1209PMB1A rated at 12,5 W, 4900 rpm & 57 dBA Upper fan is SUNON PF92251V1-000U-S99 rated at 4,7 W, 4500 rpm & 46 dBA After trying some setting: Hex8A1 Chip Frequency : 250 Hex8A1 Chip Core Voltage : 980 Hex8A1 Set ASIC difficulty to one : 1 Ampere usage on 12 V rail is 30 A Alright, so the bottom one is the pain in the ass Do you think about any replacement options? I'm still on the looks for good fans right now BTW: 30 A are quite ok, so you get approximately 1,44W/GH with this settings ,right? (i have avg 250GH/s) Even with that 4900 rpm, the heatsink is very hot. So i don't want to replace the fan That is my rough measurement since i had to measure on 3 wire So around 1,44 - 1,5 W/GH. |

My board is just arrived too! First screenshot from hashing :
Wooo, you had big PSU there |

This time i am very satisfied with speedy The parcel already cleared from custom. I just call DHL office & they said they will deliver the parcel tomorrow Congrats Zich:) Thanks loshia Going to prepare new PSU tonight Hi Zich, Can I ask which PSU/model you're using ? Thanks Of course, i am using OCZ ZT 750  Sorry for late reply, my board just arrived. So a bit busy here |

this actually is transil.
to limit peeks from the PSU
Okay... but half of the chips aren't working properly [Chip1 Nonces] => 242
[Chip2 Nonces] => 5
[Chip3 Nonces] => 0
[Chip4 Nonces] => 0
[Chip5 Nonces] => 0
[Chip6 Nonces] => 0
[Chip7 Nonces] => 0
[Chip8 Nonces] => 0
[Chip9 Nonces] => 1768
[Chip10 Nonces] => 1751
[Chip11 Nonces] => 969
[Chip12 Nonces] => 1748
[Chip13 Nonces] => 1769
[Chip14 Nonces] => 1774
[Chip15 Nonces] => 1857
[Chip16 Nonces] => 1848
Is there something I can check/fix before this board is going back for repair? I am afraid nothing else you can do. |

That's was huge heatsink . Seem like use 2 different type FAN, right stiffla? Can not be sure until the parcel arrived. |

I have ordered from the 30' piece hex8 with the better express shipping, this shipping was 46 euro. But my package is still in sofia soon 2 days. . Why is this express delivery? For more price i want much more speed ^^ i know very well that technobit cannot do anything with this, but i want answers. The shipping destination is hungary.

Shame they have sold out the pre production run. I was interested in one. If anyone is looking to sell one at a fair mark up i would be interested.
March batch is available with reduced price. You can get one from there. But the price and roi does not bother you right? Any way there will be enough guys with board in hand after a couple of days and you can get one with reasonable markup. However i am not selling mine I am just looking to collect different types of hardware. If nobody can give me a fair offer soon I will just order for march. Thanks I would just hang fire. Someone might get 3x and realize they don't like the noise of 6x Sunon 4500rpm fans! Someone on the TerraMine thread asked what the noise was like, and the reply was, "loud enough your wife will leave you if you don't switch it off". Well Sunon 4500rpm are that noisy too! Unless you leave enough space between wife and fans Or you leave the wife first Apart of the jocks they are noisy and dangerous. I was thinking gator is not right about it but in fact he is. Watch it Gator. This ones are even more dangerous compared to previous ones In general you can live without a finger or two but what bothers me much is the electricity. So kids and wife's are forbidden! that is why I keep my stuff locked always and it is only me who goes there. That is what all of us should do to be able to enjoy our families. I have 15 Kw in my room wires everywhere. A single wrong move can cost a lot LOL, you make my imagination goes wild by saying new one more dangerous Can't wait to see what kind of heatsink & fan upgrade |

so I just received 3 boards today. I opened one board to check it and one fan is broken on the edges and some nuts are missing to keep the fans on the board....it is not a deal breaker, but the nuts should have been there I will test the boards in the evening with my less powerful 40A PSU (still waiting on my new ones). How do I have to set clock and voltage? Or should I just try to decrease the voltage until it is stable? You can set all via web of tplink or you can read changelog all settings are inside. A friendly advise. DO NOT CONNECT MORE THAN ONE BOARD TO 40 AMPS. NEVER! 40 amps at at the edge. Magic PSU smoke is very close I did see the pictures you had only one PCI-E connected! A lot of multi rail PSUs (Platimax 1500W) have 30A rails I assume 2x 30A rails will be fine? More than fine Gator. in your case underclock/undervoltage even one can be fine. Just measure it if you can but on 12V rail not at the wall This is my tool for measuring 12V rail current usage hey it is an expensive one my is up to 10A and completely useless for hex8  Yeah , since i am ex service engineer, i can't help to use good quality one |

I will get upset if you do not post something like this I am jocking of course do not push the board too much  My reject rate is little bit high due to my primary pool issues and moving back and forth to backup/primary, besides guld sucks in terms of rejects for me personally this is with Set diff-to-one 0 - i am testing it and it is looking good with tplink of course TO ALL - Such high clock and voltage values are not recommended Use them at your OWN RISK!!!!! Honestly I can't wait to post |
