ZTEX USB-FPGA Modules 1.15x and 1.15y: 215 and 860 MH/s FPGA Boards

[stcupp]

Manufacturers of regulator chips usually headline the highest efficiency achieveable which is usually at the smallest input/output difference. It's not unusual for a 12V to 1.2V regulator circuit to be around 75-80% even if the headline says 90%+. Best efficiency is rarely at maximum current either.

Yohan

Yep, very true note how a converter might say 95% efficiency but doing 12v to 1.2v conversion at full load theyre more like 75-85% a lot of manufacturers show graphs or a table of efficiency at different voltages and loads in their data sheets

anyone have "y" board working with new BFG/CG miner ??
i`m using built version, as all of you know

i was using -S auto and few -S 1/2/3 commands, but nothink seems to work
any experiences ??

I need cgminer to hook "y" up with gpumax.

[rupy]

Ok, could you add a zero error rate command... that lowers the frequency until error rate is = 0.00% forever?

Yes, a error rate limit this can be added easily. I put it on the todo list for the next release (in June).

Thank you!

Which OS are you using? I had some problems to figure correct rights, but that was under Linux.

OS needs libusb-1.0 and no extra flag is required (no -S). What does 'built version' mean? If you are building from source don't forget --enable-ztex.

What about Win7 32 ? Tried it today, downloaded Zadig and installed the WinUSB drivers. Was working fine, the boards showed up as ZTEX Modules. When i started cgminer it froze and said something like "capability missing 0 7"... what did i wrong ? I also use a BitForce single and 2 GPUs on this machine.

I was getting this from time to time on linux (BAMT debian) CGMiner 2.4.1. Changed back to BTCMiner + Phoenix

And the AOZ1025 is not super efficient.

How do you determine that? The efficiency mainly depends from the external components, namely the lower mosfet and the inductor.

Based on the efficiency graph on page 6 http://www.aosmd.com/res/data_sheets/AOZ1025DI.pdf which has been measured with an AO4722 MOSFET.

Capability 0 7 is multi fpga, and that is normal if you also have any 1.15x connected. I never had a cgminer freeze with fpgas, but I also never had an 1.15y to play with so I'll need more details to be able to add anything useful to this issue. Can you start in text mode and debug (-T -D) and send me the full output until the freeze?

I switched back to BTCminer. Thanks for your help but I already deleted Zadig It was 4x boards, no y involved. Just wanted to know if I missed something important.

I wonder where I got the y from... oh well. In that case, the capability missing was actually a good sign, so unless you try again and provide the logs I have no clue to why it hangs.

BTC payment is not accepted?

BTC payments are processed per email. Currently fees are 4% + 4 BTC.

"Built edition" - builded by ckovalis - i`m linuxes lef handed bandit :/

Just installed libsub-1.0 and sommehing has changed...
cgminer can see ztex now, but cannot acces it. Cannot paste right error code.
I need to fight with my laptop first

It means there was a timeout trying to send the 'set fpga' command to your quad. It should not matter if it is an isolated incident, are you seeing more of those?

[ummas]

I can`t connect to my rig via ssh atm, but i remembder 1 each 10-15sec.
Seccond/third thing is lots of rejects(could be gpumax problem) and lots of HW ....

I just moved somme jy fpga into new case. Alle in one with mitx atom.
I was compiling cgminer by myself
Installed all.
But i got still error -9
Cgminer can see 4 (all conected) quads, but gives me error nr 9

That's the first I see that error. It's a usb read pipe error, so maybe a permissions problem? I've never tested this on an atom so I don't know if there are other pitfalls to worry about.

First fullcover waterblock "print' - http://www.abload.de/img/fcpga1wc6kutn.jpg

Next week should be ready for testing...
I myst just check somme more specs in the board, and decude, to cool power section or not?

Any advice?
Material? Copper + pkexi.
