I see, so different PSU on one host.
Yeah, I figure out when powering 6x Hex16b, if you use a power protected hub, multiple PSU works fine. I noticed some lose Capacitor legs on this bad Hex8A1. Maybe they got broken in packing or shipping but the one on the right looks like a horrible solder joint. Not sure if this would stop it hashing though. I'm not an expert at electronics. Wish I was! Look like the voltage stand on 800mv even with 1000mv setting. Actually my board also had same broken capacitor leg but cause by my self . But i just join it with his friend there( the one you point by single red arrow) Did yours stop working with broken capacitor leg? I pushed the legs to touch the nearest resistor. It powered up with it's sister 220/880 ran for 5 mins, then crashed the power supply. The bad one had green and orange light as always. The good one had two green lights and a red light after crashing. After rebooting the good one went back to two green lights and started working. The bad one refused to reboot again. I think there is some charge building up in the bad one after 5mins which causes the PSU to trip failsafe, then that charge is still held for some time, which stops it rebooting back up, but a day later it will. I'm going to give it one last try and run it on it's own TP-Link. How do I upgrade an old TP-Link from 0_1_0 to 0_2_0? Do I flash the "factory.bin" file or do I use the "sysupgrade.bin" file. It's not in factory condition anymore, so I guess it's an upgrade, but I've only seen people mention the factory file? Syspgrade is ok. Make sure after upgrade you fill all web boxes and leave nothing empty in cgminer config except pools if you are using less than three

Ok got Bad Boy on it's own PSU and TP-Link and now it's hashing! 220GH/260W Some hardware errors, that's probably the caps with bad legs. Still has green and orange light. Bad Boy hates company! I'll try and tape out the +5V and Ground in the USB cable and see if that makes him play nice with the others!

Ok got Bad Boy on it's own PSU and TP-Link and now it's hashing! 220GH/260W Some hardware errors, that's probably the caps with bad legs. Still has green and orange light. Bad Boy hates company! I'll try and tape out the +5V and Ground in the USB cable and see if that makes him play nice with the others! Gator I am repeating this constantly over and over give it more voltage to reduce hw errors they are pretty good now

Good to see that one is still working Gator So I see you did add 3 arctic f9 to the good girl, right? Are they sufficient enough and not that noisy?

Ok taped out the USB cables but still it crashes... The complete Hex family... So ruled out leaking USB power now. So I try and run Bad Boy & Good Girl together to rule out Hex16B cannot run with Hex8A1 Nope not that either, they both crashed. So now I'm running Bad Boy on it's own with the family. This is to rule in the ThermalTake 730W PSU is the problem not Bad Boy. So far so good. I'll leave it running like this until Monday morning. But it looks like the ThermalTake 730W PSU is the problem. Either it cannot handle 450-500W on it's 684W rail, or it's detecting both miners together as some kinds of fault. Looks like I'll be back at Scan in the morning for another PSU. Any suggestions? Anyone got 2x Hex8A1 running on one PSU? I'm thinking Corsair 750W this time.

Both of them work okay with 3x Arctic F9 fans at 220/880 they don't feel any hotter than a cold cup of tea and you have a pleasant whoosh like leaves blowing in the wind to listen to instead of a vacuum cleaner. They're in a cool North facing room, with no heating on, and no windows open. Bad Boy draws 40W more than Good Girl but does give 20GH extra. He feels like a slightly warmer cup of "hurry up and drink before it goes cold" tea. If anyone wants to swap a working Hex8A1 for my 6x Hex16B (F9 Fanned 270GH/415W) let me know. I'm after GH/W more than pure hashing power. I'd be happy to give up 60GH to save 200W.

Do you have this power supply? http://www.techpowerup.com/reviews/Thermaltake/SP-730P/1.htmlIf so, it is a pretty old group regulated one. The voltages on it will go a little wonky if you're pulling a lot of current from the 12V rail and nothing from the 5V rail.

I will give it a try. Maybe an old hard drive on a molex cable?

FULL STEAM AHEAD! The numbers are still settling down, not this good in reality, but yeah looks like the 5V fan trick is working!

Did yours stop working with broken capacitor leg? I was really careful with unpacking and handling, I know caps are always the weakest electronic part. I do have a soldering iron, if I knew what needed soldering to what I could maybe fix it, but it's unclear where these legs were attached. I pushed the legs to touch the nearest micro resistor. It powered up with it's sister 220/880 ran for 5 mins, then crashed the power supply.
The capacitor leg broke while i clean thermal paste right after the miner arrived. So i didn't powered it up until i fix it Maybe marto can give some advised where to join to This is what i did Luckily until now the board run without problem & the voltage is pretty stable.

Ok it's had overnight to settle down. The numbers are worse than I thought on my quiet fan modified Hex8A1's. Hex8A1 364GH/423W = 0.86GH/W or 1.16W/GH I'll try upping the mV to 900 my target is 200GH each!

Ok this is 220/900 Diff:1 430GH/505W = 0.85GH/W 1.17W/GH Heatsink and fans seem to be coping with it. They starting to become pretty good space heaters by now though. One or two of these per room and you should be sorted for heating. Warm cup of tea time, not too hot to drink though, just right! Gonna set it to Diff:0 and let it settle in. If anyone has any hints or suggestions let me know. Like should I run the Hex16 and Hex8 on separate TP-Links? Would it make any difference? Diff:1 does seem to show better results for the Hex8.

I am also still experiment with the setting. My method is use diff 1 to find stable hashing speed then set back to 0. After that observe for more than 12 hour. If speed reduced to many then find other setting. My first setting 265 - 1035 only last for 12 hour then hash rate drop to 254Gh/s. To hot i guess Now testing 260 - 1005. Already run for 11 hour & only drop to 258Gh/s. Seem more stable

I received my HEX8, compiled cgminer with --enable-hexminerb and --enable-hexminer8. It detects my 3 HEX16B and the HEX8A1, but the hashrate of the HEX8A1 is displayed as zero (while the hexBs work OK). What could be the problem? Also, the fan is quite loud

From same psu like your hexb's? Post clock and voltage pls

1.A Chieftec 450W PSU 2.Different - though I had no problems running my BFL Single from the 450W PSU and the HEXBs from the another PSU. 3.And this was my mistake. The technobit site says that "HEX8A1 defaults: --hexminer8-set-diff-to-one 0 --hexminer8-chip-mask 255 --hexminer8-voltage 1000 --hexminer8-options 8:260", but it didn't say that I have to specify these options, that if I do not specify them the miner does not work (for example, I do not have to specify any command line options for the hex-b to work).

Chieftec 450W is two rails +12V1 (21 A), +12V2 (18 A), Max +12V 360W, 1x 8Pin PCI-E http://www.idealo.co.uk/compare/2826454/chieftec-iarena-80plus-450w.htmlYou might struggle to run it on that. My miners were 368W and 408W each at Defaults! Get a larger single rails PSU or try underclocking it. 2-3. The options were blank I copied across the numbers from the (Default #) in the text to the left of the option. Also you need to change Handle USB detect errors as (Default: hexA) to Hex8 option.

I forgot about the power, now that I acutally went and looked, it's a 600W model with 46A single rail. It has two PCI-e connectors, but they both share the same cable - the wires are warm, but not hot... 2-3. The options were blank I copied across the numbers from the (Default #) in the text to the left of the option. Also you need to change Handle USB detect errors as (Default: hexA) to Hex8 option.
I didn't change that, but for now it runs OK. Is this a compile option (I only compiled it with support for hexb and hex8) or a command line option?
