Can I replace Pentium III with a faster CPU, or overclock?

[fred2]

I have a ECS P6BAT-A+ motherboard with an Intel Pentium IIIE CPU running at 733MHz, with WindowsXP. Can I remove this from its socket and replace it with something faster please? Or can I safely overclock?

I ask because computer parts that are a few years old can be obtained very cheaply from eBay, so it may be worth doing.

By the way. the Pentium III is mounted into something that sticks out at 90 degrees to the motherboard, and the alternative socket on the motherboard for lower spec CPUs is not used.

The details appended below were obtained by using Everest Home Edition.

Everest never shows my CPU temperature but I recall that is is shown as being about blood heat (37 def C) in the BIOS display.

Thanks

fred.

Looking on the ECS website (link via the "sticky" above) I get this information for compatible CPUs:
Intel Pentium !!! 750 (256K,100MHz,Socket 370)
Intel Pentium !!! 850 (256K,100MHz,Socket 370)

I seem to have the first one already. The second one would offer only a 13% increase in speed.

However, the existing Pentium IIIE does not use the actual socket 370, but is plugged into something sticking up at right angles to the board. I don't know if this makes any difference.

Thanks.

Something like this?

Do you have any money to invest in a new cheap machine?
Or you just want to have an upgrade?

[viili]

Very likely any P3 socket370 chip with coppermine core (more than 1.65V core voltage) works in that motherboard, so fastest you can get is 1.13GHz. Fast Slot1 P3:s are rare and expensive and have no other benefits than that you won't need a "Slotket", which you already have.

1.13GHz sSpec SL5QK (rare)
1.00GHz sSpecs SL52R, SL5B3, SL4MF, SL4C8, SL5FQ, SL5DV

Edit: About overclocking, you are already running your memory and chipset at their specified limit, 133MHz, so you'd be overclocking all the other components along with the processor. My guess would be that you'd run into problems after 150MHz, and that'd be mere 825MHz processor speed, and as such not really worth it.

[Guest]

The thing that sticks up at 90 degrees does not touch or use the 370 socket at all. So I'm not sure if its something like that, without a picture.

I do not want to invest in a new machine as I do not need one, its just than improving my current old computer only costs a few pounds/dollars to buy the best components.

[Guest]

Thanks, as far as I can see the Pentium IIIE chip I currently have does not physically use the 370 socket - unless this refers to a software thing rather than a hardware thing.

Would the CPUs you have described be pin-identical with a Pentium IIIE, or would other CPUs be please?

Thanks

the fastest possible CPU it can run is a coppermine PIII 1400.

[Wizzard1]

There is no coppermine PIII-anything above 1133Mhz. Tualatin PIII are the core revision which allowed speeds up to 1.4Ghz (and 1.5Ghz in Celeron).

There is so much to remember that sometimes something slips in between...

[Marcin]

with FCPGA->FCPGA2 adapter you can put PIII Tualatin 1400 on this motherboard

[MiLToS_666]

As Marcin recommended, I've installed a PIII-S 1.4GHz in my old QDI Advance 9 motherboard last year. It's also using the VIA Apollo Pro 133 chipset like your motherboard and it will most probably work fine too. I used one of those cheap FCPGA->FCPGA2 adapters from "Lin-Lin" found on eBay.
If you need any info with this procedure I can help you.
It might need a BIOS update too, or just microcode update within the BIOS to recognize the new CPU.
If you're not bored to read, have a look on this topic, you'll find my posts too.
