After the 3 day in town delivery UPS finally get you May I can try helping Dear Martin,
... So i tried your boards with hexmine in win7, tried all the combinations got 42gh with one board, 77ghs with two, 91gh with three, 101gh with foor it's little wired why its slowing down when you add another device, it's suppose to be additional. ... ThanksMy first thought from reading that is that your boards are being starved of power as you connect more. Have you tried running each one singularly to make sure they perform okay. Then try them together on different power sources (if you have two or more PSU's available), so you've got PSU one to board one, and PSU two to board two etc, and let us know the results. What settings are you using in Hexminer, can you post a screenshot? It's seems power issue but 2 of 500w psu connecting 4 boards only.What is the make model of your power supply? It's probably got multiple low amp rails. I use 350w/450w Enermax PSUs they spread the molex on 3 seperate wires and only cost <£30/$40 they run 3x/4x Hex16B no problem. CIRCLE RAW POWER 500 WATTHard to find any info on this PSU I could only find this graphic in the Google cache as originals seem to be deleted from their web site. If correct it may have only 28A x 12V = 336W on the 12v rail. But their web site says it's dual 12v rails so maybe it's 335W/2 = 168W max on a single rail/wire. That would explain why it's only powering 2x Hex16B.

This is the Hex16A2 (Hex16C) thread and 4x 24GH would be 96GH+ so 101 GH seems normal. If they are Hex16B don't run them all on the same length of wire because you will be using the same PSU rail.

Today, I am getting my second TP-Link MR3020 Router (obviously, I bricked the first one ). To prevent bricking the device again, what are the steps that have to be taken? 1. Connect router to PC and connect with IP 192.168.0.254 2. Flash router with openwrt+ cgminer from technobit website( 0.1.5 release) 3. connect tp-link router to my homenetwork router( IP range is 192.168.0.0 - 255) 4. Connect to tp-link via 192.168.0.99 and set a userpassword. Save and Apply. 5. Set all parameters in cgminer window which are necessary. Save and Apply 6. Connect Hex16a2 boards with powerd usb hub to tp-link and start cgminer.
Is this right? The reason I am asking is, because I can not really explain why my last router bricked, that's the reason for the dumb question Thanks in advance! I couldn't connect to mine after flashing, some things you should note. Wifi is dissabled to save memory in the latest firmware so you got to connect it to your PC/Laptop with the Cat5UTP network cable. I then had to turn DHCP off and manually set the IP in my laptop/pc to be on the same subnet before I could see it. The only way to brick it really is to turn it off while it's in the middle of installing the new firmware.

I don't know what fans the Antminer uses but there are some seriously fast fans out there.
The U1 has no fan. You're thinking about the S1. Advice still stands though, larger surface area via heatsinks, and/or more air passing over the surface via a faster CFM rated fan. Another option is run your stuff in a tank of mineral oil and pump that through a radiator with fans blowing through them. Some seriously insane liquid cooling... http://bitell.sinaapp.com/show.php?tid=938..but you can do it on a smaller scale at home in a fish tank with PC radiator/pump/fans.

I don't know what fans the Antminer uses but there are some seriously fast fans out there. You need to look for higher CFM to move more air faster over the cooling surfaces. Also try and build a wind tunnel so it enters one side and exits the other. I was recently supplied with Sunon 4.7W 4500RPM 75CFM on a Hex16B miner http://www.alliedelec.com/search/productdetail.aspx?SKU=70226025They are insane but there are even faster ones available from this supplier!

Lots and lots of USB errors:
I have two 8 board stacks of bitbury boards. One stack has 2 broken usb connectors so I run 6 USB cables to it and have the other two connected via CANBUS.
I had this stack connected to a PC running Linux and it worked pretty well (average about 370-380 GH/s for the whole stack). That Linux PC recently died though and now I have it connected to a raspberry pi using a power 7-port hub.
The raspberry pi is running rasbian and the latest cgminer build for bitburner and I got lots of errors like: [2014-01-13 16:49:12] BTB 4 usb transfer read error(-1): LIBUSB_ERROR_IO
Performance is also signficantly worse, at about 325GH/s (about a 50GH/s drop).
I have another stack of 8 bitburner boards connected with 5 USB cables (the rest via CANBUS). It has always performed worse than the other at about 340 GH/s. It's been connected to a raspberry pi too.
The worst part is that a couple times a day, they wiill just crash with a USB error and I'll have to power cycle the boards and restart cgminer. This never happeend with the Linux PC. Only with the raspberry pis.
Has anyone had any success getting the bitburners to work reliably with raspberry pis or do I just need to invest in some more linux PCs?
I believe it's a problem with the raspberry pi design. I don't know if they ever fixed it on later models but it had a known USB issues. The official response was that it was a power supply issue. See: http://www.raspberrypi.org/phpBB3/viewtopic.php?t=12097An alternative some are using is a TP-Link router with OpenWRT. See: http://wiki.openwrt.org/toh/tp-link/tl-mr3020Also make sure you never use a USB1 hub. It may work for a while but it will cause random USB issues because of how slow it is.

You should be more careful next time Some lawyer type is gonna pop one day, if they ship enough of these out, because the Sunon fan spec sheet says it should be used with a fan guard to avoid injury, guess who they'll blame after some kid sticks a finger in it. But any way I still do want them badly You're crazy to want finger munching fans that sound like leaf blowers in you home! But I'll let you know when I get them swapped out for Arctic F9s and put them up for sale.

I am jealous because this fans are not on mine You won't be after you catch your finger on one. One slight touch and it's slice-slice! Picture don't show it well but it put 2 slices in the end of my little finger.

I just removed a fan and holly crap the fans on my second shipment are 4.7W 4500RPM 75CFM 47dBA!!! http://www.alliedelec.com/search/productdetail.aspx?SKU=70226025#tab=specsThey were only 2W 3000RPM 51CFM 34dBA Sunons on my last Hex16B. Seriously these fans are dangerous at 4500RPM without a guard. Watch out for your fingers! Noisy as hell too. UPDATE: Just set all the 4500RPM fans to 5v. They probably still do 1875 RPM 31CFM. Seem to be keeping things cool enough for now. Got some Arctic F9 on order, just the regular 1800RPM 43CFM ones without temp control, cheap as chips. Ok, now i feel so stupid looking for replacement Fan. The SUNON Maglev PF92251V1-000U-S99 is PWM fan, so what i need is to build PWM fan controller. Did you choose this fan? I noticed the PWM blue/yellow wires were chopped off to make it non-PWM It would probably be best to run them at 7v by plugging the ground into the 5v (+12V-+5V=7V), then it should be 2625RPM 43.75CFM, but I'm not sure how the board or other peoples PSU will handle it. Soldering in a resistor on the 12v line, or even better a variable resister with 3 settings for 12v-overclocker,7v-normal,5v-underclocked, probably the safest option. The Arctic F9 (AFACO-09000-GBA01) non-PWM non-temp control fan is good combination of airflow/quiet/price/safety.

Slot 0, usually the 16x one nearest the CPU, has to be populated first before you can add other cards.
Did you try a second card? Read the motherboard manual and see which it says is slot 0.

The limit for a consumer product is the household mains ring.
KnC will breach the limits of standard US power sockets with their next batch and ship US under-clocked/cores disabled.
They said this may be their last consumer unit.

6 voltage regulators for 8 chips?
I suspect it's a flexible prototype board. If they are not needed Martin will leave them off on the production models. Some of the Hex16B come with 2 or 1, whatever it takes to get the chips running I suppose. It's planned to have 2x 6-Pin PCI-E power connectors, Martin said they are capable of running well beyond the 75W PCI-E standard.

To connect this board to windows 7 all i need to do is download hex miner 1.0.0.3 and plug it to my desktop psu or is there more downloads needed?
I heard about stratum proxy, is that needed as well?
What does it do?
Sorry for noob questions.
This video shows you how to run a Hex miner from Windows... http://www.youtube.com/watch?v=l9SgoVm16SwYou're better off using a TP-Link router for running cgminer on though, it's only 2W of power!

Ok, so it has to be a PSU. hmm X_X I have a spare Xilence 550W. Unfortunately it has 7 black cables and 1 green one. The label looks like this. I am counting 9 fields per row (2 rows) The connector to the mainboard hat 10 connectors per row (2 rows) How do I identify the correct black cable? This power supply says it has 2x +12v rails... 17A x 12V = 204W 18A x 12V = 216W ...treat it like it's a 420W Power supply and don't put more than 204W on any single line! Also always read the small print on the wires for the AWG max amp/watt load too just in case it's lower than 204W. Here is a chart with the performance of HEX16A2, keep in mind that the consumption may not be very accurate:
1000/0900mV ~24W - 15.86GH/s - 1.51W/GH (less than 1% HW) 1300/1020mV ~56W - 20.30GH/s - 2.76W/GH (less than 2% HW) 1400/1060mV ~74W - 21.28GH/s - 3.47W/GH (less than 2% HW) 1500/1120mV ~92W - 22.85GH/s - 4.03W/GH (less than 2% HW) 1600/1160mV ~108W - 24.15GH/s - 4.47W/GH (less than 3% HW) - hot
As you can see the efficiency drops dramatically when overclocked. The power connector of the boards is a standard molex which is rated to deliver upto 132W at 12V, HEX16A had similar power consumption and that was not an issue. However I recommend you to stay bellow 1500Mhz, the hashrate gain just ain't worth it. Source: 2Good

Best option would be to use any cheap psu with green and black shortcuted. (...)
Thank you for the reply a) What do you mean by "green and black shortcuted" b) How would I actually power-on the PSU? That is exactly what I mean You need to shortcut green wire with black wire on 24 pin mother board connector otherwise it will not start And additional advise make your wire connections tight otherwise they can melt http://m.youtube.com/watch?v=6xLy8rZRjU8&desktop_uri=%2Fwatch%3Fv%3D6xLy8rZRjU8They melt because you load too much power onto one wire. Try to spread the load out to as many wires as you can. Never take the PSU to it's max box wattage, some of its watts are for the 5v and motherboard. Try an get single power rail PSU if you can as that helps avoid some loading issues as well. I know dude, but they also melt when molex is crapy with bad pin contact or you are in a hurry and just spike two wires and tape them That was I what I tried to explain S I know ur a pro, I mean the msg for the newbies, sorry for confusion.
