I've currently got a pentium 2 - 400. My mobo is an Asus P2B (slot 1), which has a bus speed of 100mhz. I have checked the Asus site, and the maximum I can upgrade to with a slot 1 cpu is a Pentium 3 600. However, I've seen articles which suggest you can use a Slocket to allow you to use the FCPGA Flip-Chips on a Slot 1 mobo. The maximum speed Flip-Chip I've seen advertised running with a bus speed of 100mhz is a Pentium 3 850. Does anyone know if I'll be able to use this with the Asus mobo? I don't mind messing about with the BIOS and changing jumpers, but I don't really want to get involved with overclocking, if that's neccesary...
 
Chances are that you can actually go significantly higher than 600. Take a look at

BIOS rev '1011' or later will get you to 800MHz even without overclocking. You can download the BIOS and flash the motherboard according to instructions (but do it only if necessary, though) Research the "PCB revision" before taking the plunge, too. I don't know off-hand what that acronym means. If it's hardware, you may not have it. You'll have to look for the definitions of categories in that table.

If you don't have a Slot1 adapter, I highly recommend the ASUS S370-DL ($15-$18, depending on the vendor). This slotket has no resistors to block HS/fan installation, but it does have jumpers to deliver voltage to the core at default or increased settings with 0.05 increments if your PIII chip fails to post after increasing the FSB. And don't be afraid to up the voltage with a PIII chip. Just keep an eye on the CPU temperature and back off if it passes 60C (a conservative limit, actually).


Note: I recommend that you get a PIII700E flipchip. Available for $137 from Upgrade planet (or choose your vendor), this processor is a remarkably stable processor for overclocking. I know you said you that you are not necessarily into overclocking, but I can tell you that this chip is a champ. Buy the chip and fan (they'll bundle a Golden ORB for another 16 bucks), and the slotket, and you can make 933MHz if your ram can hang (Just set the board for 133MHz FSB, that simple). This setting will NOT overclock the PCI bus, but it WILL overclock the AGP channel. If you are using a PCI graphics card.. not a problem. If AGP, it will depend on what you've got in the slot. Nvidea Geforce chips don't object to the higher MHZ.
If you install the PIII chip and heat sink carefully (just make sure that you have thermal paste there and don't damage the chip while installing), these chips WON'T die.

For proof take a look at

http://www.overclockers.com/ (CPU database)

As you can see, you don't have to put your case in the freezer to get it to post 933MHz. You've got REAL potential here. Use it !!!

That's realy good! Thanks! I'll have to look into the PCB revision, but my BIOS is 1011 anyway, as I had to flash it to allow a new hard drive of > 30 Gb. I'm not too sure about overclocking a 700 P3 to 933, as I can't afford to buy another PC if I blow it up! Would I be able to continue with 100 SDRam or would I need to get 133 SDRam instead?

Thanks anyway.......at least I know now I can at least double my CPU speed.....!
 
Blow it up? If you overclock a chip and it doesn't work, it won't fail, it will simply lock or crash programs until you turn it back down. Set at 1.75 volts most PIII 700s will happily run 933, and still be well bellow the maximum allowable voltage as posted by Intel.

Suicide is painless...........
 
There are half a dozen options between 100MHz FSB and 133MHz FSB. Your PC100 ram will probably tolerate 133, but there's a 124MHz option if it doesn't post at 133. Just increment the voltage up to 2volts before you give up on 133MHz. That'll give you 933MHz. Did you load the ASUS probe utility ? Do so. There's a temperature monitor that you can watch after with every boot. Just load the processor with a looping game demo or something, while running the utility (it shows a 20 minute scrolling chart so you can see the average and peak temp). That'll give you an idea of just how far you can push the processor.

And DON'T worry about frying the chip. That's only a problem with that other chipmaker. You can always back off and 'settle' for a moderate overclock in the unlikely event that 933 is unattainable. It'll happily boot when it is within range again.

Have fun !
 
A word to the wise... I was able to push one 800E chip to 992 (124FSB), but only with 1.85 voltage setting (100% stable, and not running over 50C). My first 800E chip made it to 1066 (140FSB), so this was a disappointment !!! BUT, the 700E made it to 980 (140FSB/35PCI/94AGP) at default voltage, for $40 less. Smooth as silk, 100% stable, and averaging 50C under load. 933 should be a snap. That's why I recommend the 700E. Just check the overclockers.com (CPU pages) for confirmation. If graphics adapter or memory stability is the limiting factor, just go as high as you can. It's free speed !!!
 
Thanks again guys.....

Presumably, though, if I just want to get a 800mhz P3 I don't need to over clock it, do I? Just change the jumper settings, etc as required?
 
Yeah- almost any motherboard can handle any clock speed (using same generation CPU's and chipsets) as long as the bus speed can be adjusted and the ability to change the multiplier exists.
