They've named it a PGA

(PGA0) I chose PGA as the 3 letter shortening of FPGA
I guess using PGA avoided having to create a new ASIC type in the API

Or just google for "pin grid array"

I'm sure Jeff can confirm these numbers on his device as well.

My review included raw numbers -- search for "cgminer status"

Here is an updated cgminer status snapshot: http://pastebin.com/8mKjmTSn

Readers may search for "temp" to find what I presume to be temperature sensor readings. Fan speed is also observed via "fan" data.

Heh funny I didn't think of it before ...

(which I'll decide on shortly)

solo mining w/ eloipool + high diff

Good luck. Are you going for a block no matter how long it takes?

Thanks for the luck, it apparently helped!

The following is, as far as I know, the first block found by a publicly released ASIC miner:
http://blockexplorer.com/block/00000000000001528a3fa72b86032459e1fb6ab38720e19a26e3a1f4a64e461a

So far all known ASIC vendors have been highly ethical and not used their mining power on mainnet, which could mean that block #220386 is the first ASIC block found.

Will it mine for as long as it takes? I imagine it will make more sense to mine on a pool once other ASIC miners start hitting mainnet. The average block production time, for the moment, should be around 2 days, 4 hours.

Very nice. Congrats!
Do you mind sharing how you set up eloipool for ASIC mining? I want to learn how to do so in case I want/need to solo mine. Thanks!

Why's there 12 pages and there's only one damn ASIC owner besides the federation

If I'm right; give me reasons

Maybe Jeff can heat up a room to 85F or so and let it run to see what happens.

Avalon is designed to operate at 35C, not a problem.

That entire heatsink on each card is saturated at 50C! Holy hell on a crutch!

Are those IR pics accurate? That seems excessive... if it actually is 40 - 50C, what's going to happen to them in hot weather?

Maybe Jeff can heat up a room to 85F or so and let it run to see what happens.

Why would he want to do that? I think we can guess what happens. Either they slow down or it hits a temp cutoff that shuts down mining. FYI, high temperatures will have adverse effects on mining operations. What happens to BFL singles when they get too hot, they down-clock until they are within the optimal temperature range.

I don't know if you noticed, but many parts of the world get to be 85F or more during the summer months. Personally, I would want to know if my expensive mining hardware was going to shutdown when the temp rose as it would dictate how much power I had to consume to cool the thing with an AC unit. Maybe you don't care, but I sure as hell would.

Inaba: Hey, lets do some scientific and procedural testing so we can determine an outcome given a set of constants (hardware) and variables (temperature).
Dalkore: That's stupid. It's either going to be situation A or situation B. I don't know which, and I have no way of finding out unless we follow Inaba's suggestion, but it's still stupid.

Even better, get a sheet of IR-transparent plexiglass and put it where the missing side of the case should be so that the fans can generate proper airflow, and then take the thermal images again.

overheating is not the issue here. see http://imgur.com/a/5Gqix

as for memleak, we found it but that didn't solve all the issues.

expect a controller update soon and a newsletter.

+1 what? I am unclear how one can interpret those pics without knowing what is too hot for this gear. Am i supposed to think i can compare it to gpu cards and how hot they get?

What numbers exactly? Does the gui report temp values?

Good they found a memleak but if it did not solve all issues... What exact issues remain?

Avalon ASIC miner is currently surviving >24 hour stretches without restarting, now that we're on a stable pool with a reasonably high difficulty value (BTC Guild, difficulty 32.0).

However, have now seen the machine get "stuck" in a strange state, where it is not mining or restarting. The fans ramp up, then ramp down, in a cycle.

BTC Guild is the most advanced and best pool on the planet.

Maybe this is why we've only 3 ASICs in the wild at present?

It's great that Avalon was first to market and all, but your unit was specifically intended for review and it seems sort of...

HALF BAKED

If its a true review, he would have said "This shit doesnt work, still prototyping. Buyers beware"

You know like any real review of a product being sold in working state.
