Upgrading LX board to a faster Celeron

Right now I'm running a Celeron 400 @ 450, but I'm looking to go up to about 600-700mhz, as it'll provide a really cheap and simple upgrade.

With the voltage differences, would the newer Celerons run on my Shuttle LX board? If so, how high should I expect to overclock it? I'm looking to up the bus speed to about 75 or 83mhz, which would be about a little less than 100mhz increase or so for each of the CPUs.
 
Older LX boards do not support the lower voltages required by Coppermine processors. It depends on the manufacturer how low they have implemented the voltage regulator.....some go down to 2.0 volts, others such as ASUS go down to as low as 1.80 volts. You can probably run Celerons at 1.80 volts....just set the slotket manually to 1.80 volts....anything else and the system will not boot.

Remember to also get the latest BIOS update for your motherboards to recognise Coppermine processors.
 
It depends on the individual boards, whether it supports the coppermine core and how if it can handle the lower voltage required by the Coppermine Celery's.
If it'll accept the Coppermine Celery's than you could pop in up to a Celeron 766, otherwise your limited to a PPGA Celeron 533.
 
My friend's motherboard is a Intel 440LX and even with the latest bios flash from intel it would not boot up at all with the new celeron II. I ended up buying him a PPGA 533 mhz and overclocking the fsb until it was ~600 mhz. Not bad of a speed upgrade considering he used to have a P2 266 mhz. Hope that helped 🙂
 
You're stuck with the PPGA 533 Celeron as the fastest for an LX board. Don't bother. Higher FSB's is the way to go!
 
No, I think he can go higher. The only question is whether his BIOS will freak out and refuse to POST on sight of a newer breed of Celeron. As for voltage and electrical compatibility, any good Slot 1 > Socket 370 adapter will take care of that for Coppermine-core CPU's.

You really should be asking Shuttle, though 😉

Exactly what I'm talking about. The BIOS is not capable of posting any speed greater than 533mhz..
 
I went to shuttle/spacewalker's website and there wasn't much mention on the coppermine cores. There's a BIOS update for my board but it's dated sometime in '98..
 
I am 99% sure that a coppermine cpu will NOT work on an LX board. Manufacturers are simply not updating their bios so that they will recognize a celeron II chip. If you attempt to put one in, all it'll do is not post at all.
 
It's not really a question of whether the LX chipset on the motherboard will support the Coppermine, it's whether the motherboard manufacturer will implement support in the BIOS.

If the last update for the BIOS was back in 1998, then it's doubtful it would support the Coppermine, even though you may be able to force the voltage with the slotket. Although the slotket may have settings down to 1.3 volts, the motherboard may not be able to send such a low voltage anyway.
 
No one here has mentioned the PL-iP3 from Powerleap.

It is an adapter supposed to work on a LX mobo and allow up to PIII 850MHz or so, including Celeron 700s.

The catch is that Powerleap adapters work in some cases, and in other cases they don't.

I still have an LX mobo too, but I'm so frustrated with Powerleap's yoyo functionality that I have refused to give them any money for this adapter.

If you want to check their BBS, here is the address http://208.55.28.22/cgi_local/Ultimate.cgi?action=intro. But don't complain to me if you get any headaches with their product. 🙂
