No...it's called,"Mining at home" 

Compared to collecting battletanks?

That's one expensive hobby.

People do it all the time, it's called a hobby.

Must be nice having so much money you can just throw it away for fun.

NOW that is a sexual experience right there.

*drool*

Here you go.

Lightfoot Here is a plot for you of the Cortex listings:

Feel free to leave comments in the sheet and here

Because it is there.

C

Windows, and that's because my dedicated laptop that wasn't in use was running 4.5. Last night was hard, just got in from days of travel (NY, ATL, etc) and my brain is toasty.

I'll upgrade to 4.8 tonight then take a more in-depth look. So since you have these things, please post about what you have seen, what you observe. Have you taken them apart yet? Powered them down? Stuck them out a window (mine currently is in the window blowing the hot air *out* of the house :-)

C

Is that on windows or linux, any reason to not use 4.7 or 4.8? I thought monarch support just started at 4.7?
Do you also see messages like "sanity check, device is processing unknown work, device is missing queued job. device flushed (goes by too fast), failed to find work for queue results" in the bfgminer cmd window?

be patient - thats what this thread is here to find out

nice how far can these things be pushed in terms of overclocking ?

Sure, engines are like that and all, the 65nm would sometimes come up with 15 engines, 14, even 8 engines if you were doing odd clocking things. The trick was balancing everything. Hm.

So what do we have here? 128 "cortexes", each being 4-6gh in power, and 1800 "engines" on the board. So 64 cortex things, 900 engines per chip approx..

Hm. Back on the old 65mn chips you had 16 engines per chip, 8 chips per board, but the engines were buried and only the "chip" showed up as an exposed thing. Here it seems like there is another level, we have 900 or so engines on a die, arranged into 64 virtual "chips". So each virtual "chip" has around 14-15 engines hashing at 6gh, it's kind of like putting a whole bunch of little 428mh engines and letting them run wild on a set of problems.

Need to think about this overnight, not sure how BFG is assigning jobs to the chips or whatnot. Need sleep, anyone else feel free to chime in on what they see.

Quick scan tells me the slowest is:
CORTEX-07: 2240MH/s

And the fastest is:
CORTEX-40: 6928MH/s

That's an huge difference if you'd ask me. Keep the info coming, it's really interesting to see!

OK

That is very interesting. More in a bit.

C

She's up. Running bfgminer 4.5.0 and started hashing with no problems. Running right now with both plugs and a Corsair 500 power supply, plug area is a bit warm. Cables are not. Board temp at back is 119f right behind the chips, 105 overall pretty much all around.

Hash speed 660gh. Not bad. It's making a high pitch squeak from the power supplies, probably the chokes resonating from the frequency. Interesting.

More in next post. How this thing works....

C

Well, it's here. 700gh sticker, solid little thing, BFL Monarch.

Can't power it up because I have to go out. Will try to get it running in the Danger lab later this evening. Bad assed looking thing though, the board is *solid*

C

No actually this one is in hand from a guy, I've talked to him and seems legit. I will at least run it for a day or two before taking it apart, wonder what kind of thermal mating compound I will need.

One big thing will be baselines, need to know what the temps are on the backs of the chips and the FET drivers. Watch it with the scope to see what the clock rates are, stuff like that.

We'll find out Thursday. I'm really curious to see what this thing looks like and what makes it go.
