17 Avalon photos

[johnyj]

Ok, now can you take those photos down until you watermark them?
Because I can guarantee if you leave them like they are they will end up on ebay on scam listings.

The community thanks you.

Thanks for point that out, I thought the exif in the image is enough to identify, but maybe not everyone is so careful 

[Uuno]

Yeah, not everybody even know that exif data is so watermarking would be good thing to do.

I saw the first photo of the power plug. I get the end that plugs into the AVALON, but the other end that plugs into the wall is not what I use in my home - USA.

The attached picture is what I have at my home and that doesn't seem compatible with the power cord picture.

That's a Chinese plug that comes with the unit. You will have to use a standard ATX power supply plug for your home.

Mine came with a regular US power cord.  The power cord pictured was not delivered to the US.

It's a regular ATX power supply.  Any IEC power cable will work.

did u ever find out how to solo mine with eloipool?

Nice one the new picture with the snow. 

Poor little Avalon unit, I hope it has recovered.

does anyone know if its possible to install a 240V outlet with this style of plug?

That's a NEMA 5-20 outlet which is spec'ed for 120V.  To do it properly just use a 6-20 outlet for 240V, it's pretty trivial to wire it up.  See here:

since i want to run 3 Avalons off this one 240V outlet and they come with the Nema 5-20 power cords, i assume there is a surge protector available that has Nema 6-20 plugs?

Edited last post to add link for C13/6-20P power cable.

For power strips, I use this one -
http://internationalconfig.com/icc6.asp?item=60820

It's a bit pricey (~$220 iirc) but you could run 6 Avalons on it safely with enough headroom.

[cypherdoc]

sorry not to be clear, but to save money on cords what i'm looking for is a surge protector that will plug into the Nema 6-20 240V outlet and have 6 or so outlets of the Nema 5-20 style so as to be able to use the power cords supplied by Avalon.

i did google around for this but can't find any sources.

[coretechs]

NEMA 5 series is rated for 125V maximum.  I'm sure you *could* do it but I wouldn't, personally.  FWIW, one Avalon should mine enough in a day at the current difficulty/exg. rate to pay for the whole 6-20 setup...

Did anyone try to add little heatsinks to each of the chips and did it lead to better performance somehow? Maybe more stable overclocking?

no one's mentioned doing that yet.

[Joe_Bauers]

3 hashunit-v1. On left side of hashing unit, just after the fan, I observed lot's of dirt, it means unit has been thoroughly tested for days

I wonder how many BTC's they generate before it is deemed a valid test???

Thats something im wondering about. I read somewhere about people trying to overclock with software and finding a magical wall at a setting of 300(something). I read about plans of oil submerged or water cooling but no real things were someone did such thing. Or if someone were able to overclock it some more. Maybe voltmodding or somehow change the clockrate or something that can be done.
Maybe the reason is only that no one will shut down his machine for testing or dont want to risk the miner.
But i think once the batch 3 avalons come in this topic will become more important because the difficulty will be a good chunk higher then.

the only revelation in regards to heatsinking is ngzhang's strong recommendation to leave the case shut as shipped utilizing the case itself as a heatsink and generating positive pressure to help expel heat.  apparently even stacking these things create an even larger block of a heatsink.  not sure i get the concept but they're the experts.

Official Avalon Wiki strongly discourage doing this.

Dr. Zhang recommend NOT to add any heatsinks on these chips and saying that will reduce the surface airflow for PCB board

hi,

here are some info and advise.

about the plastic sheets: please remove them BEFORE mining. we design the case as a part of heatsink, so remove the plastic sheets may help. no need for remove them clean and tidy.

about FAN change: DO NOT change the fans to a low speed model. will cause over heat. DO NOT install extra fans at the rear "fan socket". will cause PSU over heat and nearly useless for module cooling.

about install extra heat-sinks on each avalon chip: please do not do that. there is a air gap between the die and package top, install a heatsink on chip is useless. and will cause overheating. because  the top PCB copper act as a heatsink too. do not cover them.

about water cooling: yes, do it.

I'm interested in opening one of the module's heatsink and have a look at the contacts, but since there are so many small units, it is not as easy as opening a GPU heatsink, I might wait until some time later when outdoor temp rised above 15c. Currently outdoor temp is -5c, I only need to worry about snowflakes
