Topic: An (even more) optimized version of cpuminer (pooler's cpuminer, CPU-only) - page 58. (Read 1958475 times)

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 [email protected] 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?

I've seen quite a few boooos today as well but I don't know that that has anything to do with the new miner.

As a data point, I get 38.5kh/s on 3 cores of a 4.3ghz 2500k. So, about 13kh/s per core (verified by running 4 cores/4 threads). Previously, I was getting about 10.5kh/s per core.

2.1.5 compiled on ubuntu 11.10, i7 2700k @ 4.5GHz
Not sure what the problem is exactly, this happened a few times

As was heralded by aaa801, here is

Version 2.1.5

• New optimizations for Sandy Bridge (recent Intel processors) and Bulldozer (AMD FX series). The speedup should range from 25% for Intel to 45% for AMD, but only in 64-bit mode.
• Building on Windows should now be possible without having to perform satanic rituals.
• Building on Solaris using gcc should now work out of the box. (Thanks to pontius!)

The source code is, as always, available at GitHub. Binaries will be available soon available here.

Many thanks go to aaa801, shakti, and xurious for letting me use their CPUs during the development process!

yeah, my sandy-i7-2600k at 4.6_ghz/8_threads/w7_64 does ~59 khash/s   version 2.1.5

thx for the excellent work

U guys should love whats coming up

depends if it has xop and avx

Holy shit, I'm regretting that I didn't buy an fx. (Kidding, but still, daaaaamn)

Will Phenoms see any improvement? Right now my 955BE at 3.9GHz is getting 7 khash/s per thread.
