Heh - damn shame about that hey.
That's what they have on the web site right now also.

I guess BFL just don't give a shit - coz it was OK back in May, and those who have made comment about it since then have been ignored.

It was OK when I originally download the 792:
alphaminer_792.bfl 7112003 sha256sum: 5fced0f00338d6aa513719fc2e6e67e765bdbb832c0c5c8f9a44dded30004f7b

I tested that not long ago and found mine worked fine - before I switched back to 880.

Went the whole summer at 768.  It's not like they didn't know.  I know that I am not alone. Really, how long does it take to put the correct version on the web site. I am seriously not impressed.  Underwhelming.

Same here; I'm not too worried... we'll all be mining with ASIC soon anyway

We'll worry about such tweaks at that time.

If you want I can put my 792 up somewhere for you to download.
Just PM me if you want and I'll give you a link.

And yes I actually find me offering to do that hysterical - me who hates BFL and they hate me too - but yeah I'll put up the download for you if you want anyway - no trouble for me and I've already got it ready to grab

Edit: and in case you only have md5sum:

fred0, even after you get a binary for 792, be prepared for it to be flakey.

It didn't work well for me, and there have been other reports of problems also.

Fortunately for me, with my device and in my ambient temp, 800 works fine.

Well, the 768 is flakey too.  Also, at current ambient temps, I was able to bump up to 800 without a problem. August was significantly cooler than July.  But I still have one unit that when it hits 78 degrees throttles on the 800 MH firmware. Likely 792 would be the right version, but it's not available. [annoyed]

In any case, BFL-Engineer said that he would look into the problem 30 May
https://bitcointalk.org/index.php?topic=80497.msg930143#msg930143 .  

It really only takes minutesseconds to see the corrupted file. So, what is the problem? It's not like this subject hasn't come up. [more annoyed]

[LazyOtto]

fred0, I have been mis-quoted here.

Could you fix that, please?

edit: fixed. Thank you.

"So, what is the problem?"

To understate it, neither accurate statements nor customer service is BFL's strong suite.

Perhaps you should expect a resolution in 'four to six weeks'.

Weird, I previewed it, and it looked good..fixed, I think..

Already off the 792 bitstream.  It is too flakey, back to 768. At least 768 is usable.  BFL should just delete the firmware entry for the 792.

Out of curiosity, is there some information on what ambient temperature is "good" for a Single? Seeing it's so temperature sensitive.

At which temp does it start to break down?

FPGA Singles are designed to work without throttling using the stock 832Mhps firmware and stock fan(s), case on, up to 75F ambient. Beyond that, they each have their own unique 'personality'.

23-ish C, that's reasonable for a home

How much heat does a Single generate? (to get an idea how much the ambient temperature actually rises from the Single itself)

How much heat does a Single generate? (to get an idea how much the ambient temperature actually rises from the Single itself)

A Single running 832Mhps firmware dissipates 80W of heat (that includes the A/C adapter losses). Halfway between a 60W and 100W lightbulb. How much that will affect ambient depends on many factors including room size and air circulation rate.

If you are running just 1, you may not notice a difference at all. If you are running 10, you most definitely will.

Thanks Or just spread the 10 around the house to heat up rooms :p

Of course, you would need a host PC as well. And typical PCs use more than 80W ... you probably wouldn't want to spread them around *too* much or you'd need a lot of PCs.

I assume a raspberry pi can power it? Small and tiny, maybe stick it somewhere on the BFL case itself

And owning one raspberry pi more or less is never a bad thing, they come in handy for everything :p media centers, reverse proxies, cameras just now as well

I like how you think.

When I use Easyminer, it displays a temperature of 325 degrees... Everything sent to the unit is also throttled

What am I doing wrong? (it's obviously not so hot here :p room temp is 19 degrees C)

[Epoch]

When I use Easyminer, it displays a temperature of 325 degrees... Everything sent to the unit is also throttled

First question: Are you using a Jalapeno or Single with Easyminer? As far as I know Easyminer only supports the old FPGA Singles at the moment. The latest Easyminer version is 1.0.9.

Are you certain the unit is throttling? Throttling is indicated by the unit's front LED flashing about once per second for 10-15 seconds. Is this the behaviour you are seeing?

A reported temp of 325 (F or C) is clearly wrong; the unit would fry long before that. You may have a faulty temperature sensor, or the communication between the PC and your unit is flakey (bad USB hub or port, for example).

When you run Easyminer with your unit plugged in, what does Easyminer display (i.e. does it correctly recognize the unit type, port, etc.)? Are you able to run the Easyminer unit diagnostics on the unit? If so, what is the result?

You may want to try a different USB port; if you are using a hub, try plugging your unit directly into a port on your PC. I've used Easyminer quite a bit (though not in the last few months), just to run diagnostics and load firmware, not for mining.

The more details you can provide about your setup, the more likely that someone here will be able to help.

Got it working, apparently it was because of the power supply being not adequate... Changed it and all is well, no throttling (it was indeed throttling, the led was blinking and easyminer v1.2 beta said so too)

It was the old FPGA Single

One last question, I got it running in cgminer now, and it reports 52 degrees C as temp. How hot does the Single FPGA usually get?

Glad to see you have it working. 52C is fine; most of my units run between 65-75C and I have a couple that touch 80C. I have replaced the stock fans with slower, quieter ones which is why my temps are so high. As long as your unit doesn't throttle, you are fine. Each Single seems to have a different threshold, though.

With your temperature being as low as they are, you may want to consider loading a faster firmware for a hashrate boost.
