I've still got 3 GPUs running.  But they're doing scrypt, auto-converting to BTC thanks to scryptguild.  Free power, so it's all good.  I've got a 280X in one machine, and a pair of 750Ti in another.  The Ti's are brilliant, 300kH for £89 and with two of them in a Core2Quad machine, the whole machine is using 195W.  Less than the 280X is using on it's own doing 720kH.

I agree, I was expecting a motherboard with a Coincraft or something built in.

To be fair, Biostar isn't exactly a big mobo manufacturer.  I think the last Biostar board I used had a socket for a 387SX...

Yes, they're rubbish.  Buy a better PSU.

Apart from needing two PCI-E cables for the S1, there's no reason why you can't do what you're proposing, assuming your PSU can manage to power both.

It's not exactly a motherboard either, is it?     I'm guessing it another board of Avalon2 chips?

Crap article.

Have you heard of "weekends"?  Most people don't work on Saturday and Sunday. 

Eclipse is a nice pool if you need PPS.  It's stable, and it's reliable.  It's just a shame a lot of folks don't like Josh due to the BFL end of his business, but as a pool op he does seem to do a good job.

I split my hashing between BTC Guild and Eligius, and the really dodgy miners that can't stay stable, or are really slow, I run in PPS on EMC.

?

All of them.

I suggest you read the README.ASIC file - I'm confident you'll find the answer you need in there.

Well it's not the BIOS that's the problem if you flipped the switch and it's not working on the other BIOS.  The card must have just fried by coincidence, or you've damaged it some way unplugging and plugging it.

RMA time.

Edit: Why did you flash the BIOS anyway?  I run a MSI 280X and I didn't flash the BIOS, and it's mining like a champ at 715kH.

Shame most SHA256 are/were pump'n'dump and fizzle out in a few weeks, never to be seen again.

I don't understand how this works.  No fees, and you're adding 25% to payments?  Where is the extra 25% coming from?     Sounds a bit dodgy to me...

Did you flip the BIOS switch on the card to use the backup BIOS?

Aw crap, failsafe again. *sigh*

This last few days isn't exactly giving me a warm fuzzy feeling where Eligius is concerned.

Yes, I patched cgminer on both machines.  The TL3020 ran the Technobit supplied firmware.

I think there may be some issue with power feeding back through the USB ports, because something seems to be nuking the USB (enough to fry the TL3020 and killing off the USB on the PC and BBB until they're power cycled).

I currently use a Celeron NUC.  It's the Celeron 847 (dual 1.1GHz), with 2GB RAM and a 30GB SSD.  It runs Windows 7 perfectly, though I run Debian Wheezy on mine.  It uses 15W at most, usually about 8W.

I also just got a new NUC DN2820  which is even more power efficient, and uses cheaper 2.5" SATA drives (the 847 NUC only uses mSATA SSDs). It uses less than 10W flat out with a SSD.  Mine uses 12W with a 320GB 7200rpm Seagate Momentus Thin drive in it.  When the drive is spun down it uses 6W.  It's also faster than the 847, and has 3x USB3 ports.

cpuminer != cgminer

I've got 5 of these boards.  They all stopped working at the same time.  First the TL3020 went dead, and now the boards won't fire up.  The PSU appears to be OK (it runs my other mining gear OK).  I've tried them on a BeagleBone Black, but it won't pick up the boards, same with a PC, same with a RaspPi running MinePeon.

The fans still run OK, and I've tried different PSUs on separate boards.  There's no lights on the boards.

Any clue why this might have happened?   Is there any way of getting a repair (considering I bought these second-hand)?

Will try the new version this evening with my HEX16A2 boards.
