Devfee Diff depends on pool, it sets the Diff. Some pools set high Diff for devfee wallet to reduce server load, if set devfee Diff 1/20 of main Diff, miner will send devfee shares with same speed as main shares (though devfee shares will be in 20 times cheaper than main shares), but it will cause high pool server load because it must check all shares, both main and devfee. By setting high devfee Diff, pool reduces its load by almost 50%. If devfee Diff is same as main Diff, you will find about 1 devfee share for 19 main shares (exactly as described in readme file), you can check this stat: enable debug logging, run miner for an hour or longer, then check log file and calculate shares ratio.

It makes sense - 1st case 8 threads x 2MB =16 but you have only 15MB L3 therefore the second case is faster. Try 7 threads.

tks,

only one problem is why

Pool Diff 25000.1
DevFee: Pool Diff 35000.1

readme show : 1/20 share for you ,  how to confirm the share diff ?

Make sure that miners shows "fast mode enabled" message. If so, the only thing you can do is to try different number of threads and see the speed. With 15MB cache 6 or 7 threads is the best (Windows and/or other apps can "eat" some cache). No other options are available.

ok.

if I use two e5-2620 2.0G with 6core,
L3 cache = 15M

"one thread takes 2MB" ??!!

then , how can I got higher speed?

======================

 

Speed depends on L3 cache size, one thread takes 2MB. So if you have L3 cache =10MB you won't get better speed if you set threads >5, instead, you can get even worse speed.

hi, dev, are u here ?

I need your help

I use xeon E5645 2.4G /2proc, totle 24cpu, and use 3.3 version for win64

when I use  18 proc,  Speed: 185 h/s,
        I use  16 proc, Speed: 250 h/s,
     then I use 8 proc, Speed: 261 h/s,

why ??

and 16P got more share than 8p , why speed not faster ?

so , how to set cpu proc number will be better !?

Hi Claymore,

What you think about this:

Microsoft Security Essentials said: "File NsCpuCNMiner32.exe contain trojan Win32/CoinMiner.AD"

Archive was download just now from you link: https://drive.google.com/folderview?id=0B69wv2iqszefSzYyM3BTYXVxZGs&usp=sharing from first page of this forum.

164 H/s on AMD Fx 4130 Quad. Can't remember hashrate on other miners, mining along with Claymore GPU (4x R9 290) on this rig.

Yes, post some hashrates for AMD CPUs please. FX series, A10, Opteron ... I couldn't find any performace of this miner on AMD CPUs.

any performance info for amd fx processors?

Is there a workaround to reboot? After some time of using computer, HR drops to half and after restarting of miner I got "not enough memory error". Even when I close every possible program and get used RAM lower than its after restart, I can´t get rid of this message. 64bit Win7 w 8GB and i7 3770S.

Hi Claymore

you support socks proxy for mining ?

Hi to all and ( for Claymore also)
Please if somebody here have Claymore V1.0 for CPU ( not 1.1) please give me link
Thanks!

I need to see full log to see the reason. Probably second connection did not get new job for 20 min, so miner decided to disconnect from pool.

Hi, with  CPU Miner v3.3 Beta I can see this strange error (Disconnect), Why?

thank u!
because use *.bat , will displaye in taskmgr's command line,  :'(I wanna all in the pools.txt,so taskmgr's command line is not displayed.
