When the miner crashes, it can automatically restart itself, that function that gets really annoying when you want to want to make changes to settings. Does minerd have a modifier for that or is that an inherent part of Scrypt Miner?

I don't know what the Scrypt Miner GUI does, but it is possible that it restarts the minerd process if it dies. That's possible because you have two processes, where one monitors the other. You can achieve the same result with a very basic wrapper script that has minerd inside an infinite loop.

Anyway, the miner should not crash. If you experience instability problems or think there is a bug that causes it to crash, please contact me with all the details.
I have 4 miners running 24/7, and the last time one of them crashed it was because of a bug in a pre-2.0 version, back in December.

Probably an artifact of using the EC2 cloud on the free tier, it doesn't so much stop dead as it spurts every once in a while.

Guys did you notice mouse stuttering on Windows with cpuminer? I have it on low priority but there is a problem with jerky mouse movement quite often, so I sometimes have to pause or interrupt it. Maybe there is some issue with my Windows 7 though...

this may seem like a silly question but how dio I get this to run 15 cores I have a bat file but it doesn't work . I did have this working before but I don't remember what I did to get it up and running.

Code:
@echo off

START /LOW /B minerd.exe --algo scrypt --url http://mine.pool-x.eu:9332/ --PW Name.1:1 --threads 15 -r -1 -s 5

I am new to all of this so any help would be appreciated

Try

Code:
@echo off

minerd.exe --url http://mine.pool-x.eu:9332/ --userpass Name.1:1 --threads 15

It should automatically start with lowest priority.

Try without echo off, try:

Code:
minerd --url http://mine.pool-x.eu:9332/ --userpass Name.1:1 --threads 15

That's what my bat file looks like.

Well now I can get it to load if I use this
Code:
minerd -o http://mine.pool-x.eu:8337 -p(mypassword) -u (myname):1 --threads 15
But I get an http request failed URL returned error 403

Well 403 is forbidden, so you did your username or pass incorrectly (most likely user, should be .1 not :1)

Oh I figured you were using the right ports and shit. Your using pooler's miner right? This works just right for me... Try

Code:
minerd --url http://mine.pool-x.eu:8337/ --userpass Pizza.1:x --threads 15

That would connect you with user as Pizza, worker as 1, and pass as x (the : splits them).

So say your user was ian and pass was x, then it would be --userpass ian.1:x

I'm rather impressed by the optimizations.

All my processors have seen some noticeable gains by using this miner. The most notable being the Core i7 3930K @ 4.5GHz which is doing around 70 KHash/s now (total). Smiley

Even a lowly Core 2 Duo E6600 saw a nice boost.

Well played..  Grin

Version 2.2

  • Slight performance improvement for both 32-bit and 64-bit systems. In most cases this will be of the order of 0.5-0.7%, up to a maximum of about 1.5% for AVX-capable processors. For example, a Core i7 2600 @ 3.4 GHz went from 46.53 to 47.15 kh/s.
  • Support for Bitcoin mining. Mainly for the sake of completeness, since Litecoin mining is way more profitable on CPUs.

The source code is, as always, available at GitHub. Windows binaries are available here.

Many thanks to Xavia, Buller and shakti for giving me access to cutting-edge hardware!

Works very well, thank you.

I get 57-59 khash/s with Core i7-2600K @ 4,5 Ghz, Win7 x64.

Latest version took my 955 @ 3.9GHz from 7.10kh/s per thread to 7.25kh/s. Good work, that's another 2.1% increase!

I'll have to try that on my Atom N450.

Currently (with an earlier version of pooler's cpuminer), I get about 2.17 khash/s on 1 thread (OS: Debian 7 32 bit).

Then when I do 2 threads, I get about 2.30 khash/s.

I wonder what 64 bit Debian + the new cpuminer will provide...

Simplest instructions I've ever found: http://www.litecoinpool.org/help

You really don't need a GUI. There really isn't any options you can toy with in this miner that will increase or decrease your KH/s.
