Title: CPU mining problem... 8 cores VS 16 cores. Post by: ollie0108 on August 17, 2011, 06:42:05 AM Hello everyone,
sorry to bother, but this question just can't get out of my mind. I've got 3 servers now mining.(I don't have to pay for the electricity, of course) One with 2 cores, one with 8 cores, and one with 16 cores. I know CPU mining is much slower than GPU mining, but I have no choice :-\ Anyway, the problem is: My 8 core server, installed with Windows Server 2008 can hash up to 2XM/s http://i1102.photobucket.com/albums/g452/ollie0108/8.jpg But my 16 core and 2 core server, installed with FreeBSD, can only hash about 4~5M/s in total... http://i1102.photobucket.com/albums/g452/ollie0108/16.jpg Is my setting wrong? Or it's because the OS are different? Hope y'all can help me out :-[ Thanks :P Title: Re: CPU mining problem... 8 cores VS 16 cores. Post by: 1up on August 17, 2011, 06:50:53 AM Yea, that's doesn't sound right. Are you sure that the linux server is mining from both the 2 core and 16 core. With that slow mining, it almost seems that its only mining using the 2 core only.

I thought the thread number is same as the working cores?How can I make sure ??? Title: Re: CPU mining problem... 8 cores VS 16 cores. Post by: ollie0108 on August 18, 2011, 01:58:51 AM Anybody?
Please help me=( Or I can only blame it to OS? But how come Linux is slower than Wins :-X Title: Re: CPU mining problem... 8 cores VS 16 cores. Post by: runlinux on August 18, 2011, 02:13:52 AM does your install see all the cores ? (16)? if so, did you throw it the -t 16 for 16 threads?
i get about 25mh/s on my dual QX9775's at 3.2 (8 threads) Title: Re: CPU mining problem... 8 cores VS 16 cores.

Yes, my install can see all the cores(top -P, right?)i get about 25mh/s on my dual QX9775's at 3.2 (8 threads) Quote CPU: Intel(R) Xeon(R) CPU E5520 @ 2.27GHz (2266.76-MHz 686-class CPU) I didn't throw -t 16 to it, but it seems like the program did that for me because it showed FreeBSD/SMP: Multiprocessor System Detected: 16 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 cpu2 (AP): APIC ID: 2 cpu3 (AP): APIC ID: 3 cpu4 (AP): APIC ID: 4 cpu5 (AP): APIC ID: 5 cpu6 (AP): APIC ID: 6 cpu7 (AP): APIC ID: 7 cpu8 (AP): APIC ID: 16 cpu9 (AP): APIC ID: 17 cpu10 (AP): APIC ID: 18 cpu11 (AP): APIC ID: 19 cpu12 (AP): APIC ID: 20 cpu13 (AP): APIC ID: 21 cpu14 (AP): APIC ID: 22 cpu15 (AP): APIC ID: 23 [2011-08-18 10:17:38] 16 miner threads started, using SHA256 'c' algorithm. Don't know if I got it wrong :-\ And I just tried to throw -t 16 to it, doesn't change anything :( Are you using Jgarzik + FreeBSD also? |
