Bring Up My Post~ Help please.

This is really strange. I set up a new cube last night and it seemed to be running fine for about an hour, but by the time I was preparing to go to bed it had dropped to a flat 0. It seems to function in short bursts getting to ~600MH/s but always flatlines after a few seconds. I was hoping it was a problem with Slush's pool and not on my end but it doesn't look like that's the case.

Here's a shot of the configuration:

(It shows 10GH/s but within a minute of taking the screenshot it dropped back to 0)

Any advice? I tried restarting everything, including the router and my PC, but the problem persists.

First of all, a big thanks to Dogie for the setup guide.

I'm looking for the collective wisdom on the best fan replacement for the Cube. I am looking for one as quiet as I can get it while moving enough air to run in overclocked mode. Specific model recommendations would be dandy (I read earlier in the thread that someone recommended a Scythe Gentle Typhoon model), but even knowing the minimum CFM rating it needs would be very helpful.

Does the new fan have 2 wires or 3?  The cube requires a 3 wire fan (the 3rd wire is for the fan tacho, without it the cube thinks there is no fan installed, so it shuts down to stop over heating)

EDIT:

FIXED

The reason was the switch and also the router.

I hooked the CUBE and the Laptop to a "TP-LINK POE Switch" and it immediately start mining as expected. I guess the reboot comes from a watch dog which reboots when it fails to mine.

Of course the POE function of the switch is useless but at least the switch enables the Miner to mine.

I've been having a weird issue where one of my cubes randomly shuts "off"
I say off in quotes because it's still getting some power, but only 1 of the 2 power lights will be on (the 2 vertically stacked, the top stays on) and the fan continues to blow, but it pushes cold air and the device doesn't hash or respond to web requests. I can then un-plug and re-plug one of the 2 plugs (doesn't matter which) and it magically whirs to life again, for some random amount of time.

I have 2 cubes (and 1 BFL miner, no oc, total power should be < 700w) running of a Corsair AX860i, and it's always the same cube having the issue so I don't think it's a power issue. The fuse looks fine and I don't see anything wrong looking at the board.

Anyone else have this problem?

With miner you mean the proxy? The PC is not mining just for proxy

Then please tell me what I can try to change to get the network issue fixed?

The Miner is connected directly to the router same is the PC.

Is the network defective in the Miner?

My configuration is really not complicate:

mining_proxy.exe --host stratum.bitcoin.cz --port 3333 --getwork-port 8332 --stratum-port 3333

Also tried 50btc and btcguild no real difference.

tried also different but I really don't think it is the proxy.

Concerning the Long Polling. It starts with long polling then disables it then a little bit later it makes restart.

Can you tell me what is normal state of the Miner? LED OFF or LED RED ??

I wait for the 750 corsair PSU hope this can help or I have an expensive brick.

The real problem is the restart. Is there possibility to login to the device and see more info with USB or this other service port?

However the 500Watt and 650 Watt PSU can start the cube.

The 500Watt the LED stays red.
The 650Watt the LED goes off and it seems to start mining but also after exactly 2 min it reboots.

F YEAH! after giving it a bit... my slush status is "38058.182Mhash/s"!

Now that's a solid solution!  Thanks for everyone's help!

Do you also use two separate workers?

Just a setup question, are you running two proxies?  (192.168.0.150 & 192.168.0.151)

Just wondering if that's the preferred method.

^ Thanks a bunch, that helped a lot! I just opened it all up again and took each blade out, and a good percentage of the heatsinks screws were loose, so I tightened all four up on each blade and powered back on; unfortunately it's the same.

Every blade works in low clock mode.

As soon as I switch to high clock and click reset they turn to x's, sometimes I get a few o's momentarily, but eventually they revert to x's.

Clicking clock mode back to low does not work unless I power off/on the PSU again.

Once the power has been turned on/off it mines at 32 gh/s in low clock mode no problems.

Anyone else here have an issue with changing the clock from low to high?

That's just for the management interface, I switched it to port 80 so it'd be the regular http port.  The cube communicates to the stratum proxy via port 8332.

*I will try it just in case, I'll switch the port back to 8000 and refresh.

*Result was no change to performance.
