[newbie] cpuinfo
Does cpuinfo show the actual cpu MHz that the cpu is running at or does it only show what it is rated at ? I'm pretty sure it shows what it is running at When I overclocked my XP2500 it reported it as an XP3200 I also _think_ you want the and 7.5 setting as there is some doubling goes on there somewhere. I can dig out my manual if required. I gather that's the way it's set now? Brian Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

As with most things the biggest problem is knowing whether there is a problem. In this case as I didn't know whether cpuinfo reported an actual value or the processor's specification I didn't know whether I had a problem. -- http://www.poogle.co.uk Want to buy your Pack or Services from MandrakeSoft?

The actual FSB frequency is 133. DDR uses the rising and falling parts of the sine wav signal to 'double' the bus. It doesn't. It gives about a 5 to 7% increase in performance over non-DDR. Your multiplier and FSB settings in bios is correct for your cpu. Many boards that don't have high multipliers, further multiply lower settings. EG, your board probly uses a 5 setting, multiplied by 3, or a 7.5 multiplied by 2. BTW, Jetway is one of the dozen or so brand names PC Chips boards are sold under. PC Chips often makes the same model board, but uses different chips and bioses on them. So whatever manual you find for that board, might not match it exactly. http://www.stud.fernuni-hagen.de/q3998142/pcchips/ -- Tom Brinkman Corpus Christi, Texas Proud to be an American Want to buy your Pack or Services from MandrakeSoft?

Second, the multiplier is normally set automatically on most modern motherboards, so even if your manual jumpers can only go to 12.5, the board is capable of autosetting itself for the 15x. The manual jumpers are only there for people that want to run their processors at something other than the default. -- /g Want to buy your Pack or Services from MandrakeSoft?

I ask because having installed an AMD 2400xp (2000MHz) FSB 266, I am unsure if I installed it correctly, the (Jetway) website has a table of cpu ratio jumper settings for a range of processors, for this one it says 15x alongside a FSB of 133 but the max range of jumper settings in the manual and on the website only goes to 12.5x. I know next to nothing about the subject so am unsure whether to go for 12.5x or is it simply a matter of :- 15 x 133 = 1995 so with a 266FSB should it be 2000/266 = 7.5 ? To further confuse me the Bios has 2 settings for frequency settings 100 or 133MHz. Output of cpuinfo :- processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 8 model name : AMD Athlon(tm) XP 2400+ stepping: 1 cpu MHz : 2008.623 cache size : 256 KB fdiv_bug: no hlt_bug : no f00f_bug: no coma_bug: no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr sse syscall mmxext 3dnowext 3dnow bogomips: 4010.80 If yours works the same way as mine, the rating of the cpu will be according to how you set the FSB in bios. I'm guessing you cureently have FSB=100 which gives you a CPU 2008.623 MHz, if you set your FSB to 133 it will then change to show CPU 2400 MHz or there abouts. Your CPU might do more if your board would support FSB 266, or is it that your board can only do FSB=133 which gives a CPU MHz of 2008.623 , while if your board would support FSB 266 it would give the CPU MHz of 2400 it's full rating, I'm not sure, form your description, which way round it is.
