cat /proc/cpuinfo My Franken-puter (collection of mismatched parts, new CPU, supposedly 1.6GHz) model name : AMD Sempron(tm stepping : 1 cpu MHz : 1044.431Dell D/top Intel Celeron R 2.2G, actual 2.192GHP laptop AMD 64bit 2.2G cpu 0 800MHzcpu 1 800MHz
Dell D600 Pentium M 1.6G, Actual 600MHZWhy so much slower than advertised? I'm bettin' the Dell desktop (XP Home) isn't actually at 2.192G either... 3 of these:  and one of these:  |

the first one, if this is not a older cpu in a newer mainboard(some mainboard with older cpus not supported can do this, i had one), you have enabled cool and quiet which makes go slower the cpu and saving some energy, also makes the fan go slower or maybe you have some cpu stepping software running? the dell one, that is the real speed, some cpus run slower than expected sometimes is just 1 or 2 mhz but you have 8 but for 8 mhz i wouldn't be worried the amd and dell pentium M laptop, this is a cpu stepping saving some power together with cool and quiet this is the way a laptop saves power when running on batteries, by lowering speed of as many parts as possible nice turtles  |

Cool & quiet? This is interesting... Is this a function of BIOS? Can I overclock this thing as well? It is a new cpu, although several years old... Anyone here ever o/c a cpu? |

cool and quiet is a function available in amd cpus, yes it can be found on bios
about overclocking, that depends on the mainboard, ram and the psu you have
overclocking involves more than just the cpu and most times you don't win a lo from the system, a improvement of 10% in some cases is just 160mhz that you won't feel, most systems will work faster by just adding more ram or putting a faster hard disk in the system(even going from ide to sata hard disk)

i forgot how low i am on cache with this cpu
processor : 0

cpu family : 15

model name : AMD Sempron(tm) Processor 2600+

bogomips : 3199.59
clflush size : 64
power management: ts ttp tm stc
in my case, the cpu is called 2600 but the real speed is 1599.796
amd says that the clock speed and the technology put together makes the cpu run as if it would be a real 2600 and based on comparisons with similar cpus, i have to agree until i have to deal with specific games that will feel the slow speed, small bus and little cache

That's not far from 10GHz.  What's the actual speed here? cat /proc/cpuinfo |

What's going on here? After I updated to KDE4, I noticed everything is much slower. Then I ran into this thread so I tried the command.

Is there an option in BIOS to switch off speedstepping or settings ??
(But then you switch off battery savings on a portable)
