What speed are your getting CPU mining TENEBRIX?

[tacotime]

So, on a 2600K with 8 threads I should get what !?

~3.8 kh/s per core

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

[Bobnova]

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.

If I get my 2600K to do around 30 khash/s I would feel EPIC !

What miner are you using, and what box config ?

Miner is the one here: https://github.com/Lolcust/Tenebrix-miner

My box is just a simple macbook with 2 CPUs and no modifications (except the fact that it's running Xubuntu).

what minerd startup options do you use ?

Maybe 4way? ;-)

LOL no wonder you are getting all of the blocks mate with that kind of speed 

So, it seems that Apple devices really are MAGICAL huh !?

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 ?

I'm waiting for this as well.

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?

No, just error in compiling.
It doesn't really earn anything... But it looks cool

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.

That's smoothie the fudmonster.  Ignore him.
