Hey guys, I'm mining LTCs woth the standard Litecoin Wallet with the 2.1.4 cpuminer "minerd.exe" and its dll libraries in the wallet directory, I have an AMD phenom x6 1090t@3.4 ghz and the maximum hashing speed I can reach is 17 kh/s, on Win7 32bit. Do you think it's a fair value? Upgrading to 64bit win7 could help me reaching an higher hashing speed?

Using a 64-bit you would probably be able to double that hash rate. My Phenom X6 @ 3.5 GHz does about 39 kh/s.

You could alternatively run win7 64bit in a virtual machine w/ miner, it still maintains about 95-97% of its speed in a VM.

VMware says that it supports emulation up to 4 CPUs, is it normal ?  It's mining speed going to get low for the lack of 2 CPUs?

Current Version: 2.1.5 (March 7, 2012) - Changelog

The current Changelog link in the first post has an incorrect url - 404.

Shouldn't it be:

Fixed, thank you.

The newest version boosted my i7-2600k up ~2.5-3 k/hash per thread.

It didn't do anything to my AMD phenom II quad-core though.  I even tried downloading it twice and replacing all the .dlls and the miner.exe again.

Even still, thanks

Don't know how to setup it on my Mac OS 10.6..   

Code:

./autogen.sh
./autogen.sh: line 8: aclocal: command not found

You don't need to build from the git repo, there's a tarball available.

@pooler Thanks for the helped! What to do for the next step? I seen the Installation Instructions(install.txt) but couldn't process 'make' after this:

Well, it looks like you're missing the C compiler. Unfortunately I don't know much about how things work on Macs, so I'll let someone else help you there.
In the meantime, have you tried using one of the precompiled binaries?

[Bitbird]

OK, Thanks anyway! Yes, I tried. But cannot figure out how to install them on Win XP as like OSX. I'm using cpuminer "stand version" for XP and Linux at present. I'm stupid in computer..

[TravisE]

This may sound obvious, but those of you with i5/i7 CPUs might do well to make sure it's actually on. On a Linux system I recently installed, it turns out I didn't have the acpi_cpufreq kernel module loaded, so Turbo Boost wasn't active. Loading that seems to have gained me a good 6–8 Kh/s or more. Wish I had discovered that sooner.

What arguments do you give to minerd to make it solo mine?

[Cosbycoin]

What arguments do you give to minerd to make it solo mine?

Argument #1: You're such a stupid miner that you can't pool mine!


Argument #2: Your momma miner is so fat that she could't fit in the pool to mine!



There ya go!

Deploying the *nix version on the cloud, two quick (kinda noobish) questions.

1. If "-t" is unspecified, does it default to max?

2. Is there any modifier for a Lazarus mode, like the function in Scrypt Miner GUI where it can restart itself after coming back from the dead?

Deploying the *nix version on the cloud, two quick (kinda noobish) questions.

1. If "-t" is unspecified, does it default to max?

It detects the total number of cores (virtual cores if the CPU(s) support hyperthreading) and uses that.

Code:

$ ./minerd --help
<snip>
-t, --threads=N       number of miner threads (default: number of processors)

2. Is there any modifier for a Lazarus mode, like the function in Scrypt Miner GUI where it can restart itself after coming back from the dead?

I'm not sure I understand what you mean, could you please explain?
