Has anyone checked if this increases utilization / increases power? Someone said temp went up so that would seem to indicate power draw is up.

I may end up doing that.

I want it to be clear to everyone that I'm rooting for GAW. I want you guys to succeed and wanted this to be a great product. It's clear that some of the issues you've had are simply a result of growing very, very fast. I'm in the startup world so I completely understand that. I had issues with some previous orders and your customer support handled it very well.

That said, there are serious issues with this line of miners (power use being the primary one) that could have been handled better. Zeus had to know about the much higher power use before they shipped. Shipping them first and then telling us "oh by the way, these draw far more power than we said and you'll need a much bigger PSU" is not the right way to handle it. I'm sure much of the blame lies with Zeus but since GAW is selling them as their own product the responsibility falls on your shoulders. Had you told us about it and given us the option to cancel before the product shipped I probably would have done that and just ordered an A2 mini. Instead of being frustrated and posting negative info I would have sung my praises about how it was handled.

The external cardboard box had no visible damage. The internal white box had a split along the bottom edge but no other visible damage.


I was the one who pointed it out to them and told them they should send out the email so I thought it was worth mentioning.

Another unhappy Falcon owner here. Rather than writing out a block of text I'll hit the important points quickly, both good and bad.

• Exceeds the original 27Mh rating, seems to average around 28Mh.
• Case looks nice.
• Packaging has inadequate shipping protection. Parts of the case were bent on mine and the screws that hold the boards on were loose. One of the fan cables was disconnected.
• Draws ~1115W consistently on a Raidmax 1000W 80 Plus Gold PSU. Coin diff has no impact on power use for me.
• Power connectors are not wired correctly and will short if you use the extra PCIe pins.
• Case fans blow air out the back (negative pressure) rather than sucking it in. This is opposite of the PSU and may cause cooling issues for the PSU.
• I won't list all the issues with the ZenController since they've been discussed elsewhere. Needless to say it feels like a prototype, not even alpha stage.
• Case is a few mm taller than 4U. This may make it unsuitable for rack mounting but I can't be sure as I haven't tested it yet.

To top it off sometime yesterday afternoon it stopped mining entirely. Sometimes it comes up as sick, sometimes it thinks it's hashing but doesn't output any results. Unfortunately I had to host it somewhere else due to power use and don't have physical access to it yet to diagnose. Hopefully I can get my hands on it today or tomorrow.

I can confirm they are using Zeus' chips. When I first looked at the chips I thought there was no writing on them but after looking more closely I can see that they say "Zeus" and a part number.

The power use of these is completely unacceptable. My 7 voltmodded gridseeds use ~60W for 2.7Mh. That means I could run 70 of them at 600W for 27Mh. My Falcon is drawing 1135W, not including 5W for the Pi.

I looked at the cgminer config on the ZenController. It has freq set to 838 which is very different than the "--ltc-clk 328" we're seeing recommended. Is the cgminer version on the ZC different than the download? Edit: Looks like freq is different. It's still using --ltc-clk 328 param along with that freq setting.

Edit again: Also looks like the config only has 1 pool in it despite setting 2 pools on the website. Why wouldn't it have them saved in the config?

Thanks. That's about the same as mine. I'm using a Raidmax RX-850AE which is 80 Plus Gold so it should be pretty efficient. Hopefully the RX-1000AE I'm going to try tomorrow will bring it down a little. This power use is a major problem for me. I could have run 700-800W on one of our circuits but 1100W+ is more than they can handle.

Why are my posts being deleted? I posted provable facts and my opinions about them. 1130W (what it's up to now) is *far* more power than the Falcon should be drawing based on what we were told. I'm going to try a 1000W PSU tomorrow to see if it has better efficiency than my 850W. I doubt it will be much lower though.

I'm going to post up an unboxing and setup video tonight.

It appears that's the way they intended to put them in but it's wrong. The PSU is trying to blow out the back, the fans out the front. You want positive pressure, not negative.

WARNING! ONLY PLUG IN A 6 PIN PCIe CONNECTOR! DO NOT PLUG IN ALL 8 PINS!

The connectors on the ASICs are wired incorrectly. The additional 2 pins are supposed to both be ground but they wired one of them to +12V. This creates a short. My PSU detected the short and refused to turn on. Hopefully all PSUs do this. If they don't you will probably melt the connector and possibly start a fire.

I am having the same problem with my Falcon. Raidmax 850W PSU taken from a working GPU miner will not turn on with any of the ASIC boards plugged in. Even if I connected the ATX and MB plugs to a working system and plug in the ASICs it refuses to turn on. Tried plugging only one board in, same result. PSU chirps and doesn't turn on.

Mine had some physical damage to the back of the case and some loose screws but no visible damage to the boards.

If you're using 230W at idle something is wrong. All of my rigs use 40-50W at idle with no vid cards, 100-120W with 3-5 cards.

Why don't you create a branch on github and let people test it? That's half the point of open source software. Anyone can help and anyone can contribute.

I compared the source against the original code to make sure there was nothing malicious. Code is fine, nothing bad has been added.

It seems to have some stability issues. I had to reboot all systems before it would work. Some of the systems then had other issues after and I had to go back to the original sgminer-sph. My 265 (7850) system is working well. One of my 270 systems worked but a few cards went sick quick. My other 270 system is now having issues booting. I also tried it on a 290x rig and I couldn't get it working, X crashes and I get a seg fault.

Unfortunately most of my rigs are remote so I can't cold boot them easily.

I'm a lurker. Doesn't matter though, it ended 45 min ago. For some reason I thought he said it ended at 6:30.

Why would anyone trust this coin? The dev is an idiot. Bad code, completely botched launch, indecisive on the relaunch (changed mind at least 3 times in 15 minutes).
