If you are that bothered about cooling, why stack the individual units upon eachother?!

Surely the ones sandwiched in the middle retain more heat than if they were standing separate to eachother... Huh

AFAIR Avalon said that they are designed to be stackable upon eachother.

Didn't know that, but w.r.t. throwing air con at them, surely it's has a negligible effect to those units sandwiched between??

Having run a room full of GPU miners, best method on the cheap is: room temp intake, shunt the exhaust outside. Done. No (increased) A/C costs.

+1. Still running 85 gpus exactly like that here.

Hi, I posted these in the pictures thread, I thought some of you might be interested in them aswell.

It was a long, but happy day now that I've received our Avalons!

That's certainly impressive, but why not just use the ducts to vent hot air out? I kind of doubt that AC is actually necessary.

I also agree. Vent the hot air directly from the Avalon to outdoors while having the AC maintain a steady room temp.
I'm sure moisture will eventually build up somewhere and cause havoc.

Yes, but they don't mean cool as in low in temperature Grin

In all seriousness, yes I could probably do it that way too. However, I have tried that method before with large GPU farms and it is somewhat inefficient and didn't work very well. Also, it gets over 100 degrees here in the summer time almost every day. This huge A/C barely keeps the room below 90 degrees, but the Avalons are much cooler because the cold air from the A/C is blowing into the intakes.

100°F is only 37°C. I think you'd be better off with a couple of these kind of things. More air is probably better then cooler air and certainly it would be cheaper...

I think he plans to expand the ASIC farm significantly over time; he's got room to expand on there. Just too bad that Avalon shipped so damn late, there's not much profit to expand with.

Anyone here knows what to add in the "more options" area?
Right now it says --real-quiet (what does this mean?)

On my batch #2, I use

--avalon-auto --avalon-freq 285-365 --avalon-temp 50

I set chip frequency at 285. The machine starts slowly and ramps up. Mine almost always stays between 343 and 347 MHz, each machine picks it's own characteristic frequency.

I am using the ck klovias 20130703 firmware.

Did you leave cgminer set to the default: "balanced," or change it to failover? Any noticeable difference in average total hash rate if you did? I am kind of scared to try balanced as I've always used failover in the past.

I tried balanced with the 3 accounts set to the same, and did not notice any difference from failover. When the 3 accounts are set to different numbers, the 1st seems to get a little bit more hashes.

Review of my order from Avalon (Rated 1 to 10):

Ease of setup: 10 (very easy to setup after you setup your first one)
Speed: 10 (they advertised 80Gh and I'm getting 97-112 Gh at 325mhz)
Package Quality: 9 (they arrived safely with plenty of padding)
Delivery: 1 (they were 3 months late)
Customer Service: ?? (I have never had to contact them for anything, I did not need to change anything about my orders, etc.)
Power Consumption: ?? (yet to be determined)
Average score: 7.5

Overall, I'm a still a little angry they delayed so long and these will hardly make ROI, but I am happy they finally came through and delivered.

Thanks Avalon!

I set them at 350 and they are doing 110MH/s each.

I seriously doubt that.

These are 4-module units so it is just about the same hash rate/module as the Batch 2 units which are doing 82 Mh/s (3-module).

GHs. Not MHs. My bold emphasis on your quote. Proper syntax is very important.

haha! good one! Grin

Bitsyncom can certainly afford to refund people at this point - 600 x BTC25 would only be BTC15k. About the cost of 1.5 boxes of chips.

It would certainly do a lot for their reputation.

If they do that, it would be yet another slap in the face of those who originally requested a refund. If most people who asked for a refund knew this at the time, I'm guessing they would just take delivery on their unit and take the partial refund.

I agree though, they would be wise to do this.

I don't think they will though.
