Hi Guys,
I need to change default API port on couple of S3's but cant find any config. When I add --api-port 4030 to cgminer, my miner is not starting.
My cgminer line is like this:

PARAMS="$AOPTIONS $POOL1 $POOL2 $POOL3 $_pb $_ow $_bec --api-listen --api-allow $_aa --api-port 4030 --bitmain-checkn2diff --bitmain-hwerror --queue 4096"

So where do I change API port?

Thank in advance

Thank you but my miners are 5 blades not 6 so I don't think they are the same. The one I have are LTC LIMITED--T SERIES.

Any idea where I can get orginal  a2 110MH version firmware? my card got corrupted and have no firmware. Im running currently OC ver 3.0 but my blades turn off and on and miner is very unstable. I have tested all other firmwares and its basically the same so need the original.

Hi,

I have a problem with my S4. I run it for about 7 days and soon after, it started to be very unstable. Hashrate would drop to 1.6 Th, after reboot it wouldn't start mining unless rebooted twice. Last night its been playing up badly so I rebooted it once, that didn't solve the problem so rebooted it again, after that my miner never came back. I had to power it off as miner wasn't responding. Since then, my miner is dead, I get LCD coming up but its blank, LED on network port is flashing, LED's on controller are on . I don't get red LED next to display so not sure what's wrong.  

Any idea? Help much appreciated.

Cheers,

One of my S3 got bricked during firmware update, browser just crashed randomly. How do I fix it?

Building "Hex flower" out of RF hub  . Curious if the board will handle the current for 19 Hex*furys... Thats almost 40A

Thats very nice Intron.   Does it get hot with 10 Hex*furys?

Hex is using around 10W. So far I've managed to push it to over 16gh and 15.7Gh avg. See below

I would appreciate if  you keep your adverts on your forums. This is Hex*fury thread! Thank you.

Are you trying to pay by card?

Just remove P110 fuse, and bridge the pads with a bit of wire. That's all   Also make sure you don't connect more than 8 Hex miners to RF hub after the mod as there will be no limits what each port can draw from psu and you don't want to overload it and brake it.

Edit:

I've noticed that if you remove fuses, you can adjust the voltage on RF hub and it will overclock your Hex  I found 5.25V works really well and its not frying the hub. With fuses the hub will perform worst if you adjust the voltage but without fuses does the job well 

Over 18hrs, 6 sticks @ 5.25V 78.5Gh avg, not to bad

Have fun 

Hey guys,

I've been playing around with razorfish hubs for a while and finally got around to modify it to remove 1.5A limit per port. I've modded 6 ports  for testing and results are awesome. Before the mod, Hex would happily hash around 11.5Gh max, but with the mod same units are 12.5-13.3GH and thats without OC. 76.9GH avg out of 6 devices 

You should (but not guaranteed) get Hex running on 500mA port however I can't say how well and how stable its going to run. 500mA is way to low and shouldn't be used to power Hex. The design of Hex requires sufficient power to be delivered otherwise your device will not perform as or above advertised speed. Just to give you quick idea see below.

- 2A+  hub will give you 12.5GH-13.5gh no OC
- 1.5A hub will give you 10.5-11.5GH
- 1A   hub will give you  6-8GH
- 0.5A -Don't even bother as may get strange problems.

With OC, Hex will use around 2.4A @ 5.6V and will give you 14.5-15.9GH.

Edit: Just to add one thing, is is very bad for your Hex to be run on 500mA port. If all chips will get initialized, its fine, but if one or 2 chips will not get initialized properly(which is very likely on such a low power), the other chips will get overclocked automatically and will get very hot and even unstable.

New cgminer is out and it fixes all issues with Hex*Fury and improve speed. Works really well.

Cheers ck!

Issue resolved  it was my xp host running out memory and crashing cgminer. Added another RAM stick and now up for over 24hrs and no problems at all.   

Not everyone is so lucky as you Also can you OC your gridseed up to 15GH? Don't think so... Hex is 50% faster  out of the box and can be overclocked to almost double the rate of gridseed
