Re: CpuFsb software -- your opinions please Well, I have two "OC projects" on the go now. One with the 500 MHz and another with a 450 MHz. Both are Dell Dimension XPS T-series (both use the SE440BX-3 mobo -- and I did manage to find the info on this board: »Intel SE440BX-3... Does it really exist? ). The 500 MHz is my primary work machine and the 450 MHz is my playing machine, so I'm going to experiment with the T450 first.
Last night I did some prelim work on my PIII 450Mhz -- I haven't made any changes yet, but did find the clock gen chip and got the PLL info, and verified that the FSB range does indeed go to 133.3 MHz. The multiplier is 4.5 (the FSB is 100MHz), hence the stock 450 MHz CPU speed. The max speed I'll be able to get is 4.5*133.3 = 600 MHz.
I'm assuming for now the T500 has the same PLL, and should have a multiplier of 5 (since it also has a FSB of 100 MHz). So I should be able to clock it to 666 MHz if I can get the FSB to 133.3 MHz. But I'll worry about this when I test out the T450.
There's one major drawback to the SE440BX-x mobo -- no CPU temp sensor!! There is a case temp sensor, but I haven't quite figured out how to access it yet. I have MBM5 running on the T450 and it's reading a temp of 41 deg on the "other" sensor that was available, but I don't know for sure it's the case sensor.
Anyway, I ordered an Alpha 1HO-P3 Fan with the Alpha 3125 HS -- so I won't be making any changes until I get it installed!
Also will upgrade both machine to PC133 SDRAM -- which should be sitting on my doorstep in a FedEx package right now.
One question for those familar with CPUFSB -- what the heck are the "Tray Frequencies" for?!?!? I don't quite understand their function, so I'd certainly it if someone could explain.

Peace!

Sebastian, FL | Cpucool uses tray frequencys.... these are tested,preset frequencys you configure that reside in your programs tray icon. You click on your preset of 133 mhz...BOOM its 133 mhz (thats where the tested by you part comes in) click back on 100 mhz ,you're at 100.
Thats how it works with CPUCool anyway.

Fort Worth, TX | Quick question... where do I find the PLL information??
Listening here, downloaded CPU Cool, and need that info!

Fredericton, NB | On your mobo, probably near the CPU, you should see a thin metallic chip about 1cm long with rounded sides. It will have the number 14.3xxx Mhz beside it. Near that chip, you'll see a small IC -- get a flashlight (and magnifying glass if you have one on hand) and look at it very closely. It should have a manufacturer tag or imprint and a series of numbers or alphanumeric codes.
Tell me exactly what you see on the chip.

If you have SiSoft Sandra...look under mainboard info. Also,CPUCool will ask you to enter your mainboard info (manufacturer&model#) when you run the program the first time.More than likely ,it will pick the right pll if you supply the right info.
As a last resort, or a first resort.......open the case and look for a small oblong shaped thing with the numbers 14.3 stamped into it(crystal oscillator or some thing) right around there is your PLL chip . It is usually about 1/2 inch rectangle with soldered connections on all 4 sides. Look for the letters, IMI,capital"w" for winbond,cypress uses a tree icon. you get the idea. each manufacturer is different. I beleive its the first set of numbers on the chip.

Sebastian, FL | Sorry Coriolis, I shoulda updated my browser before I posted I guess. You had it handled.

Heh, this is what I thought they were for -- at least the instructions more or less gave this impression -- but for some reason my version doesn't seem to be able to use them. Meaning that, nothing happens when I click on them. Oh well, guess it's not that critical.

I finally got my PeeIII 500GHz OC'd to 600MHz. Using CPUCool. :):)

Fredericton, NB | Ok, not so lucky with my PIII 500MHz chip. For some reason I can't get it above 512 MHz!! 
Part of the problem is that CPUFSB (and probably CPUCool, since they're basically the same program) has no setting between FSB speeds of 103 MHz and 124 MHz for my PLL (Cypress W149). I'm running WinNT on this box and my computer instantly crashes when I set my FSB to 124 MHz.
There must be a way to get a better range of FSB speeds... I'm just not sure how...
Anyone?

| I think that's the only settings you can choose from to overclock. I haven't seen or heard any program here or in DellTalk, Dell's support forums, where you can actually overclock in 1mhz increments. You could try to email the creator of the CPUFSB and CPUCool to see if it is possible to overclock in 1mhz increments in the registered version as the 100, 103, 124, and 133mhz settings are the only ones I see available in my non-registered version. Well best of luck. T

Fredericton, NB | It just seems weird that there's such a gap between 103 and 124. I mean, what's the benefit of raising FSB from 100 to 103? Sure would be nice if there was a 112 setting -- I know some PLL's offer this setting... just not mine. What a drag.
