Forget about turboboost, it's just a slick way to make something bad sound good.
With all cores running the CPU produces too much heat at full speed so the clock is throtled back.

Your CPU has 2 physical cores but can run 4 logical threads. HT allows 2 threads to run on
a single core but they share resources. Two threads on one core using HT is not as fast as
each thread on a dedicated core. That's why you saw the numbers you did.

Ideas for bitcoin games: download on our OS and write to any Hard drive / SSD / even USB drive about our identity.
- after that enter the email address in our config.txt file and boot rig
- login to dashboard simplemining.net using the same email we use and start managing the Smiley rig
- we can just test it for free and then pay 2 $ per rig per month
- If new miners apply by using auto-update system
- at least 1GB of system memory used (depending on how many GPUs are used from miners)
- Linux, programming, scripting, mining is a Smiley hobby we have

plexmen, if you want better results - you must overclock your northbridge to increase speed you l1,l2,l3 etc cash.

Do it in Windows task manager, details tab, right click on the program, set affinity, that's how I do it.

Hello!
Are there any chances for algo YescryptR32 to be supported? There's a new coin called WAVI (https://bitcointalk.org/index.php?topic=3146751.0) which is based on this algo.

Thanks beforehand.

cpuminer-opt-3.8.4

Added yescryptr32 algo for WAVI coin.
Added URL to API data.
Improved detection of __int128 support (Linux only)
Compile support for CPUs without SSSE3 (no binary support)

https://github.com/JayDDee/cpuminer-opt/releases/tag/v3.8.4

Additional notes:

This release may fix some recently reported compile issues related to unsupported
SIMD instructions and lack of support for __int128. This may help some older AMD CPUs
and Linux distributions that previously failed to compile.

There may be some other unknown underlying issues so YMMV. In particular Centos 6
requires a newer version of gmp that is avalable for that release.

There is no Windows binary for CPUs with SSE2 but not SSSE3. cpuminer-sse2 is built for
Intel Core2 which includes SSSE3. However, I can be bribed.

Can you take a look at the Argon2d algo and add it?
There seem to be 2 variants, for 2 coins (wonder whats the difference between the algos, but the hashrate is about 3 times faster on Credits coin than on Dynamic)

It looks like the same algo but with different parameters. It should be a straightforward implementation
because it was forked from cpuminer-opt. But I'll probably rework it to reduce code duplication/triplication.

It would be great because this fork didn't support AVX2, only AVX and AVX512f.
Waiting for adding Argon2d algo's too!

If you'r e the lucky owner of a CPU with AVX512, maybe you aren't so lucky because
v3.8.4 fails to compile. I included some experimental AVX512 code but was unable
to test compile it, and sure enough, it won't compile.

Until a new release is available you can remove the erroneous backslash in avxdefs.h line 1244
or remove the entire AVX512 block of code.

hello,

can you link a post where someone explains how to run the miner. which command etc. that would be really nice. Or maybe link that specific post or instructions in the ANN post?

cpuminer-aes-sse42 -h

replace cpuminer-aes-sse42 with the build your using, pools will also have quickstart commands/options listed

ok. so i just have to type this when i'm in the specific path of the cpuminer. where do i know what build I'm using?

Your CPU has AVX512 I presume. Read back a few posts, you can get more details here...

Mining noob here look for some help trouble shooting.
I'm trying to mine zoin. I believe i have everything set up correctly but cpuminer keeps closing out on me.
I'm on an older laptop running windows 8.1, intel i5-4210u cpu which does support avx2.
Here's my .bat "cpuminer-avx2.exe -a lyra2zoin -o stratum+tcp://zoin.netabuse.net:3000 -u mynamemyworker -p mypassword -t1"
I double click the .bat, the cmd window opens and i start hashing. I check my worker on the pools page and it shows it running. Shares submitted, shares accepted, running fine for 4-5 minutes then the cmd window closes and no more hashing.
I've given permission to the av, i'm only running 1 thread so cpu usage/temperature isn't an issue. It just quits.
Like i said i'm a total noob when it comes to mining so maybe there's something obvious i'm overlooking, but as far as i can tell it's all set up right.  Huh

If the miner is reporting shares accepted and the pool confirms it you seem to be doing (almost) everything right
and likely have a problem with your PC causing the miner to crash. Almost because you should put a pause in your
bat so the window stays open and you can see any error messages that may have been displayed.
