Re: ANTMINER S4 Discussion and Support Thread

That sounds promising.  Hopefully a firmware update will be sufficient then??

We can hope, but time will tell... It seems to have made a difference for me, at least on eligius. The pool statistics seem to be in agreement with what I'm seeing on the S4... so that is positive.

For what it is worth, I was able to cross compile the version of cgminer found here, https://github.com/bitmaintech/cgminer, for the Beagle Board Black they use as the controller. That version has some commits after the October 3rd date of the latest S4 firmware and I was hoping for the changes CK was talking about earlier in the thread. This has seemed to address the issues with eligius for me and the S4 is averaging 2119.47 GH/s over the course of 9h 55m 26s.

Re: [ANN] FIRECOIN ~ FIRE ~ FIRST X15 POW/POS ~ LAUNCHED 6/27!

I'm getting access denied when trying to mine with the X15 GPU miner you have listed.

If your are trying to mine on a P2Pool , http://fire.altmine.net/... then you need to set the no-extranonce setting in your sgminer config file.

Code:
"pools" : [
{
   "name" : "rig-01",
"url" : "stratum+tcp://fire.altmine.net:48698",
"user" : "
",
"pass" : "",
"pool-priority" : "0",
"no-extranonce" : true
}
],

GPU miner works well on P2Pool if you use the no-extranonce setting...

Code:
"pools" : [
{
    "name" : "rig-01",
"url" : "stratum+tcp://:",
"user" : "",
"pass" : "",
"pool-priority" : "0",
"no-extranonce" : true
}
],

Is the GPU miner working on bbl.altmine.net?

Doesn't seem like the current version support the --no-extranonce-subscribe, which is required for P2Pool. I compiled a version with this set, and it works fine on all p2pool nodes i tried...

Update: Place the "no-extranonce" : true in the pool settings instead of --no-extranonce-subscribe on the command line.

Just noticed that ckolivas commited a changeset a few hours ago with an update to the bitfury driver. Re-compiling from source, with those changes, made a difference in the numbers I was seeing in cgminer. Cgminer reported hash rate went from around 1.7-1.8Gh/s to around 2.2 - 2.5Gh/s.
I didn't think the changes would make such a difference, but there will be hardware errors reported now.

Anyway in case someone cares, here's an updated windows binary with the changes:
http://ck.kolivas.org/apps/cgminer/temp/cgminer-nogpu.exe

Seems to be helping my numbers a bit, on two different ubuntu boxes. Recompiling now on a beagle-board xm... will post results after a soak in.

Nice one, have you got a link to the source? My search fu has failed as I'm tired Smiley Thanks.

Hi everyone
my HD 7950 hast rate is about 375 kh/s using cgminer but I thought It maight be around 650 kh/s
I want to know how to improve it to 650 kh/s or higher
and is there another miner better than cgminer
thanks a lot

You need to have a better settings, even at stock clock you should get 550 hash...

Agreed, you will most likely have to 'tweak' your settings. Check out the cgminer SCRYPT-README for a good explanation of the 'Tuning process' for a 7970... Should be a good place to start.
