So, on a 2600K with 8 threads I should get what !?
~3.8 kh/s per core

The grue lurks in the darkest places of the earth. Its favorite diet is adventurers, but its insatiable appetite is tempered by its fear of light. No grue has ever been seen by the light of day, and few have survived its fearsome jaws to tell the tale.

AMD users: Try turning up the CPU-NB (CPU NorthBridge) speed, that's your L3 cache+memory controller. It may help.
I get about a 2% gain from having my NB at 2600mhz

Every little bit help!
Intel users will likely gain more from cranking Uncore than AMD with cpu-nb, just because the AMD doesn't have to use as much of it's L3 cache.

~3.8 kh/s per core If I get my 2600K to do around 30 khash/s I would feel EPIC !

Miner is the one here: https://github.com/Lolcust/Tenebrix-minerMy box is just a simple macbook with 2 CPUs and no modifications (except the fact that it's running Xubuntu).

For SandyBridge CPUs (corei7 with four digit model numbers).
git the package. ./configure (screw the flags) gedit Makefile find "CFLAGS = " Change that line to: CFLAGS = -march=native -O3 -Wall -msse2 -msse3 -msse4.1 -msse4.2 -msse4 -mavx Brought my performance from 2.6kh/s per core (running one thread per core) to 3.66-3.7kh/s per core.
Tested with 6 threads, +2 kh/s in total. HT works now! Just needed some hardcore flags, that's all.
I wonder if someone could compile this package for Windows i5 & i7 users ?

If you want to do a port, pick up a copy of cygwin or Visual Studio and do it yourself. It shouldn't be impossible, it's only a command line program.

Mining w/ an i3 550 @ 4ghz using virtualbox and archbang x64 in windows 32bit host my result is about 3.8kh/s / core w/ HT. Without HT its around 2.5kh/sec / core.

I have two dually xeon poweredge servers I'm going to power up today to run this new CPU miner. I just hope BTC-E comes back online for trading. I just deposited BTC to get some TBX and the damn site goes down lol

Is it possible to get 1mh/s using scrypt? OR the miner on Mac is just calculated the hashrate mistakenly?

Damn it !!! How can I optimize my crap 2600K !?
You folks with AMD Phenom II at 3.6 GHz getting 16 khash/s on only 5 cores Me with Intel 2600K at 4.2 GHz getting 9 khash/s on all 8 threads
Fuck Intel !
The 2600K doesn't have 8 real cores. It merely tricks the OS into thinking there are 2 cores for each real core to keep the CPU more efficiently loaded. Internally there are 4 actual cores. HT isn't a performance doubler because the CPU only has 4 physical cores not 8. Some applications perform slightly faster w/ HT. Some perform faster w/ HT off. All out database servers have HT turned off for example because we see higher throughput w/ HT turned off. The more the pipeline can be kept full the less advantage HT provides (eventually reducing performance when pipeline is continually full). Your comparison should be based on 4 cores not 8. The 2600K has 4 cores and will perform as 4 core processor when performance per thread is maxed out.
