Why are people even worried about this? The current run up in hashrate (from about 20-55TH) is ALL from polaris cards. Therefore the majority of miners are effected by this, which means that the relative distribution of coins among miners wont change.

To put it in simple terms, if everyones cards went from mining 30MH to 1MH overnight, your profitability would remain EXACTLY the same.

This question is not a matter of how hot the miner runs (they run fun between 50-70c on the actual chips themselves). The issue with mining and fire hazards always comes down to how YOU power them. The boards themselves are engineered well and have 2 6 pin connectors which is well within the specs of what the boards draw for power.

The issue with fire comes when you try and draw to much current from your PSU to however you are connecting the PSU to miner. The failure point is almost always between the PSU connection, wire, to miner connection. This all comes down to the gauge size of the wire used, whether your splitting that wire and if the connector/PSU can handle a splitter etc etc. Even if the actual miner runs cool, your wires could still be drawing too much current than they can handle and overheat and burn up.

Do you research pretty much all the answers on how to power miners are on here.

Two rules I always follow and you should too:
1) NEVER EVER mix PSUs with the same load (i.e. don't connect PSU 1 to connector 1, and PSU 2 to connector 2 on the same board).
2) ALWAYS assume your wires/connectors will catch fire at some point...planning around this on how you position your miners/wires and where you place them will determine whether your house burns down :p

Have a Saphire Nitro R9 380 and an XFX R9 380 for sale. Would rather sell them both together. Both have original boxes.

SOLD

As of today this rig is making 1800 per month when you factor in dual mining.

Not sure where your getting that number from. This thing is making me nearly 1500 per month currently dual mining.

Buyer fell through current asking price is currently 1.2 btc shipped.

So looks like LTC1BTC's data center caught fire....over 2TH of hashrate has disappeared....

Just logged into one of my GPU rigs i forgot about the other day ( never need to touch this thing), and check out the uptime below...can anyone beat it ?? Would have easily been double this if I didn't upgrade claymore over a month ago.

And no this is not stock BIOS (heavily undervolted....these are running @ 800mhz with about 100watts each card), and not in some datacenter (sitting in my basement).

Yes the ground lines are the most likely ones to fail when you don't have enough connectors for the current draw your pulling. This is why the higher power draw 8 pin GPU connector has two extra ground lines.

They are using seven 6 pin connectors to power 8 GPUs + aux power. This is bound to end in this type of failure eventually. Technically there should be 16 6 pin connectors to play it safe. They used the bare minimum.  (don't forget a normal 400/500 GPU is pulling half its power from the PCIE slot/riser and another half from the 6 pin).

All of my rigs are all Ubuntu server based and none of them have displays. I find using displays with mining rigs a crazy idea :p

Sale pending

I need about 36 Alcheminer/MAT boards (each whole unit has 8 boards so need about 4 units). Will take whole miners/broken boards whatever you have. Paying up to 100 per board depending on condition.

Yes I could...but this runs Ubuntu server...so if you can't at least SSH into the system and know how to edit files etc I wouldn't recommend it. Ground shipping to Kansas will be around 100USD.

that discussion is not for this thread...you can check out my other posts...either way you can't do it without custom hardware and low level changes to motherboard BIOSes. If you want a plug and play solution buy the rig

Asking around 1 BTC plus shipping.

Yes its not ship-able with 10, since they are not secured in the case.

Yes this is designed to run 24/7 in a server rack environment.

Here is a screen of the system still running. As you can see its been running 24/7 for over a month...zero downtime and temps under 60c for almost all GPUs.
