ok, i got home and try mine. this time I booted the machine on AC power (and I had to boot 5 times ).alintolea1 wrote:Now that you mention is, mine looks worse! It's a PIII 600, but looking at /proc/cpuinfo, it shows a cahce size of 16mb (which is all right, because that's at boot time, when the L2 cache si disabled) and a processor speed of 125 Mhz! And bogomips around 300 or something...swsnyder wrote:Actually, I don't believe that is a universally true statement.Sharedoc wrote: PIII-modules select 100MHz FSB automatically.
What kind of memory you have?
I replaced my P2/300/66MHz with a P3/500/100MHz, disabled the onboard RAM and the L2 cache. The newer CPU seems to be running at 66MHz.
My first thought, of course, was that I didn't have a real P3. The L2 cache, enabled via a Linux device driver, is 256KB in size. Then there is this perception of the processor by the Linux kernel:
So it seems that I really do have a non-Speedstep P3 (which is what I wanted) yet it is running at 5x66MHz, not the expected 5x100MHz.
Code: Select all

As mentioned in prior posts this is on a 600E 2645-57U with the most recent BIOS installed.
I will post the whole output tonight.
Plus, the machine doesn't seem that much faster that it was when I had the PiII 366 Mhz in it.
Something is definetly wrong
However, here's what I get from my /proc/cpuinfo :processor : 0
vendor_id : GenuineIntel

So my speed is not 6* 66 mhz (which would be 396 ). But it's close to 500 mhz, which is the speed I think all speedsteps work unless you make the speedstep mod on the MB.
Can anybody else confirm what I said here? (about the 500 mhz thing ?). I will be reading earlier posts to see what speed the unmod PIII 750s were working..
