I would like to get some info about the noise level ... the specifications says ~20 DB at 25 °C ambient temperature ... is this true and is this at max load @160 GH/s? Is it equipped with some high quality 80mm fan that adjusts speed in accordance with the temperature?

The linux build, for example this one https://www.nicehash.com/download/nightly/sgminer-5.0-daily-20141204-115-linux-amd64.zip includes all kernels (.cl files) and the sgminer binary itself - there is nothing else that you need (no other files). Run "./sgminer -n" when you extract the zip and post what you get.

edit: ehh, sorry wrong thread ... I'm interested in the "DICE" noise level

I see many of you guys struggling with manual sgminer compilation/building ... if you're just looking for latest windows/linux builds you can always take a look here: https://www.nicehash.com/download/nightly/ ... whenever a change will be made to sgminer/master or sgminer/devel, a new build will be available to download (thanks to elbandi for the automatic build system).

sgminer-5.0-daily-xxx are from master branch (aka production)
sgminer-dev-daily-xxx are from the devel branch

Thanks for the report. Huh, don't know about tweaking (I have no experiences with Spondoolies miners) ... are you trying to say that there are any individual settings that can be tweaked in accordance with configured asic wattage cap? Any other tweaks that an "undewolter" has to be aware of?

philipma1957, could you please test what kind of hash rate delivers a single SP20 when is configured to consume just below 1kw, say approx. 990W at wall?

Could this be merged with sgminer-dev/devel branch or did you hardcode some Hawaii stuff in this version?

Updated sgminer-5.1-dev builds are now also available on NiceHash download page: https://www.nicehash.com/software/#sgminer

BTW: every time a change is applied to sgminer-dev/master or sgminer-dev/develop branch, new builds are automatically generated around 03:00 UTC and are available here: https://www.nicehash.com/software/nightly/

badman74, your fork is now essentially the same as sgminer-dev/develop branch. The sgminer-dev/develop branch is intended for exactly the same thing as your fork - tuning, optimizations and new features. It would be great if you would simply code your changes in the sgminer-dev/develop branch instead of your own fork ... less work for others to merge stuff into sgminer-dev/develop branch.

Guys from Vertcoin are looking for someone to implement Lyra2RE algorithm into sgminer: http://sourceforge.net/p/sgminer/mailman/message/33026956/

Looks like a challenging and interesting job for guys like @Wolf0, @badman74 or @Slix (ystarnaud)...

Might be because your version is actually based on sgminer-master not sgminer-develop? Were there any such changes betwen master/develop that might have an impact on those issues?

Thanks to ystarnaud the sgminer-develop branch has been updated with badman74's optimizations: https://github.com/sgminer-dev/sgminer/tree/develop. And thanks to elbandi&nicehash you can already download new sgminer-5.1-develop binaries (neoscrypt algo, whirlcoin, diamond v2 and the arebyp scrypt kernel, badman74 optimizations): https://www.nicehash.com/software/#sgminer

If you really have to show pre-orders, than you should  change the way you display ROI days for a pre-order. You should count the number of days from "now" until the anticipated delivery. For example, the AIRE Miner is supposed to be available Q1 2015, taking into account the history of pre-orders this will (hopefully) happen in april 2015 ... that would make the ROI for this miner "180 + 140" days (180 days to wait until shipping starts and then another 140 days until you reach actual ROI  ... this numbers are as of today ... and keep the numbers separate). Pre-orders are especially dangerous for newbies, therefore you will do a great favor to them if you'll display a bit more conservative information for pre-orders (or just remove them all together).

When somebody will receive one of these please report on noise level ... I'm interested in the C1's vent noise level at full load (and not the vent's for the cooling radiator, because I already have these...).

I can't get any information about the dimensions of C1 miner. Does it have the same chassis as the S3 miner? If not, what are the exact external dimensions of this miner? For the S3 miner the Bitmain's web page says "Size:  331 mm x 137 mm x 160 mm", but there is no Size information for the C1 miner?

The fastest publicly available X-algo miner for AMD GPUs is most probably badman74's modded sgminer-v5 (get it here https://www.nicehash.com/software/#sgminer) ... some additional optimizations of various CL kernels were done by various individuals, but weren't publicly released. And you can get some decent income if you point it to NiceHash multi-algo service https://www.nicehash.com/multialgo.

Take a look at C) at this FAQ: https://www.nicehash.com/index.jsp?p=faq#faqg3 and also https://www.nicehash.com/index.jsp?p=faq#faqs7

The most current version of sgminer (v5) can be found here: https://bitcointalk.org/index.php?topic=632503.0

I do believe that you can consider this thread closed.

badman74, is the code on https://github.com/badman74/sgminer/ master tree the "mod" version, that is, the same that is used for your windows binaries mod?

https://bchain.info is very nice ... when will you add BURST coin? It would be great to have graphical representation of BURST difficulty.

Anybody? We really need some answers regarding the mining performance guidelines ... or is this a secret?
