So far everything works fine, I have not measured performance yet, but roughly one 4400+ core is 20% better than 3000+ from FFT-like floating point computations (double precision). I am used to run micromagnetic simulations (OOMMF), computationally intensive tasks consuming about 100Mb memory in my case. There is no much performance benefit in upgrade from 3000+ to 4400+, however 1Mb cache for each core, comparing with 512K cache, is pretty noticeable, especially when I run 2 tasks at the same time. What I did: 1) BIOS upgrade of my Abit AV8 matherboard to the latest v2.4 (http://www.abit.com.tw/cpu_support/amd-athlonX2-t.htm), despite the instructions I did not do CMOS reset 2) recompiled and installed 5.4-STABLE kernel with "options SMP", then I tested it with old single core CPU 3) cpu replacement dmesg: CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 4400+ (2247.42-MHz K8-class CPU) Origin = "AuthenticAMD" Id = 0x20f32 Stepping = 2 Features=0x178bfbff Features2=0x1 AMD Features=0xe2500800,LM,3DNow+,3DNow> Hyperthreading: 2 logical CPUs real memory = 1073676288 (1023 MB) avail memory = 1025105920 (977 MB) ACPI APIC Table: FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 ..... /Alexander Konovalenko +46-8-5537-8142 (office) +46-7-3752-2116 http://daemon.nanophys.kth.se/~kono Royal Institute of Technology (KTH) Nanostructure Physics Department, Albanova Roslagstullsbacken 21 10691 Stockholm Sweden
