+1.  Despite the "I want my coinz now!" stuff (ME included!  ), this is the best pool I've used.  Yes it has problems occasionally, but I always get my BTC in the end.

Keep up the good work wizkid.

Since MtGox price is SO far out of whack from the others, I'd like to exclude it from my average.  Acknowledging that this could be true for some other exchange in the future, I propose that every exchange has a checkbox next to its name so the user can choose which exchanges to include or exclude from the average.  For example, I'd like to exclude localbitcoins also.

Yeah - we all get the same shiny bitcoins in the end no matter how pretty or ugly (like mine!) the mining rigs are.

I think he means you need clock buffers on the board, not on the chips.  No need to worry yet.

Edit: Removed excess text.

For those of you waiting; I ordered on Nov 26 and got a "shipping" notice on Dec 4 but my order did not actually leave their facility until Dec 11.  USPS tried to deliver to my work on Saturday but no one was there so I got the order today.

I agree that this is slow shipping but I'm happy with my order.  My recommendation to Amagi Metals is to be more open an honest about what is happening with orders.  For example, do not say "in stock" if it really isn't.  Say "available in 5 to 10 business days" or whatever is appropriate.

Other than the slow shipping, I'm happy with my order.

It's best to just add heatsinks to the back of the board.  However, the parts you are cooling are the black plastic transistors between the large aluminum cylinders (the filter capacitors) and the large black cubes of metal (the inductors). 

The reason the back is better to cool than the parts directly is that the parts are mounted with a metal pad in the middle that is designed to conduct the heat into the board.  On the other hand, the top of the part is plastic and does not conduct heat as well.  Thus, cooling the back of the board is best.  Also, when you add heatsinks on the top of the parts, you risk shorting out some of the other small capacitors near the devices you are cooling.

To repeat: It is best to heatsink and cool the back of the board under the VRM, and NOT heatsink any of the individual parts.

There seems to be something strange going on with the "Global Average" number.  Even though the USD and CNY (converted to USD) prices are very close and >90% of the volume, the Global Average number is much lower than either of these prices.  That would imply the rest of the world is WAY below this price - which seems to NOT be the case. 

(I have a web page image to insert here but don't know how to do it.)

This was only true for the first revision of chips.  All of those were shipped in BFL products except a few early sample chips.  All of the other chips sent out to us were the second revision where engine 0 is working. 

With only a single LED flashing, it looks like maybe the MCU has rebooted.  

The LEDs are numbered 1 (closest to USB connector) to 8 (closest to the PCI-E power connector).  Is it LED 7 that is blinking?

I don't think this news story has been posted here yet:

I just got 2 emails that something on my account has changed even though I did not do it.  After logging in, everything looks OK as far as I can tell. 

Is this due to a recent EMC change and I can safely ignore?

Z-link is NOT working yet.  It is low on the priority list at this time.  It *might* get done in a month or so but there are other changes that are much more important.

How much slower?  How long did you let them run before deciding they are slow? 

When first powering on, they intentionally run slow then speed up based on temperature.

Yes that is correct.  Perhaps you have an older version?  2 have been released so far with 14e (1.2.14e) being the newest.

MrTeal and I have developed mining hardware called Chili using BFL chips and it uses the BLF driver.  The driver interface / protocol defines a command (ZTX) that allows cgminer to request three voltages from the hardware.  The 3 values are typically  3.3V, 1.0V, and 12V.  cgminer displays the 3.3V value on the screen but in my opinion this is the least interesting voltage value.  I would prefer it to show the (nominal) 1.0V value as this directly impacts hashing speed and power.  On other BFL hardware, this value is fixed at the factory, but on a Chili, it is configurable by software allowing automatic overclocking.  Thus the interest in displaying this value.

Please consider this reply a formal request to change the displayed value from the 3.3V value to the 1.0V value.  If you have enough screen real estate, it should show 3 digits to the right of the decimal point.  Ex: 1.057V  Thank you.

BTW - We have added a new field to the ZCX command to distinguish our hardware apart from BFL hardware:

I would recommend upgrading the firmware.  Details here:  https://bitcointalk.org/index.php?topic=304250.msg3531327#msg3531327

Is that batch 1 or 2?  There was a bug in early batch 1 boards that was fixed half way through batch 1.

Edit: Before someone asks, the bug was due to new behavior in the revision 2 ASIC chips and was fixed (a workaround) with new firmware.

If you are using cgminer, you need version 3.6.0 or higher.  I'm having good luck with 3.7.2 and I did have some problem with 3.8.1. 

75%-finished 

Thanks but that is not the problem I'm seeing.  My RPi does not freeze or lock up.  Instead it appears as if the 'q' key was pressed and cgminer quits for no apparent reason.  It happened again last night.  I will revert to an older version.

BTW - when getting source from github, now do I request an older version (such as 3.7.2)? 
I can't just go back to the ancient version I was using (3.4.2).
