Fastest CPU that'll fit in a socket 370?

[Guybrush]

I got an old HP Pavilion 6636 from a friend and am giving it to my sister, but it's only a Celeron 500. What's the fastest CPU I can stick in there? I thought I could put any socket 370 chip, which I think is a PIII 1.4, but I'm finding there's not just a PPGA, but the PPGA2 and FCPPGA, and I don't know what the differences are. I want to put a PIII 1.2 in it.

 

[Doh!]

You would need an adapter, and even with the adapter, it's not a guaranteed job. Check powerleap's website.

 

Theres a really, really good chance that your 1.2 will not work in your HP.
The 1.2 PIII is Tualitan based and runs on 133 FSB.
Not only do you have to have a Mobo that runs 133FSB, but you also need a chipset that supports Tualitan cores.
And any PC that came with a Celery 600 is not likely to support either one.

You need to tell us the Mobo's chipset and capable FSB speeds.

if a cheap adaptor doesn't work, buy a new m/b combo from frys. cheaper then powerleap and faster

Thanks everyone! Looks like a PIII 933 is the fastest thing you can put in it, it's the Intel 810 but my bios won't let me adjust the multiplier or the bus. I think i'll look into that Fry's mobo/chip combo now

Don't bother with powerleap adapters,their overpriced

You maybe able to run a Tualatin cpu on your mbrd by using an adapter from upgradeware.com ,check out thier site for more info there
(surprised you missed that one oldfart)

Inccidently ,if your mbrd can run a PIII 933 straight off it'll be able to run a 1GHz too.
Multipliers are locked on all PIIIs btw so it doesn't matter if higher values are not listed in the bios

I thought of it, but it is an HP. Hard to say what exactly the mobo is in that thing.
I also question the ability for it to run a PIII 933 (133 bus).

Most of the cheap versions of the 810 chipset only support a 100MHz fsb. I have a Dell Optiplex with the 810 chipset that won't run a coppermine even with the latest bios update. :frown:

Hey oldfart, do you think this scroll down to motherboards will work on a CUSL2? It currently runs a P3 733 on a 183MHz fsb with the memory set to 149MHz. It also runs synched at 166MHz easily. I know the pci bus is getting ridiculously high, but it is stable as a rock. My thinking is that the steppings of the Celeron 1.0a are getting so good, I might be able to run one at 166MHz for 1660MHz. Not bad for a $19 motherboard and a $35 cpu.

I have noticed that in benchmarks that are all cpu with no bandwidth needed, the Tualatin usually bests the Athlon at the same clock speeds. Of course since the platform is limited to 150MHz sdram, the 400MHz+ DDR platform of the Athlon leaves the socket 370 way behind.

I have been intrigued to say the least with the performance of the Pentium M processors. Intel claims a bunch of internal changes, but I believe most of those are bull and we are seeing a Tualatin-like cpu with a bunch of L2 cache running on a 400MHz or better fsb. I know this is a pipe dream, but my thinking is that if somebody could actually make a convertor for a 370 pin cpu to fit on a 478 pin motherboard, wow! I think we would then have very close to Pentium M performance on a desktop for $35 a pop. With a 10 multiplier and a little overclocking, presto, the Celeron 1.0a is a perfect candidate for a cheap version of a Pentium M 1.5 or 1.6GHz.

You know that Intel will do everything it can to keep a Pentium M from making to desktop cpu duty. I mean they could never see that people would like a faster, cheaper and cooler solution to the P4 :disgust:

Well according to Anandtechs article about the Pentium M it is a radically different CPU to the PIIIs ,though it does have its rootes there as well as the P4.
And you'll never see a S370 to 478 adapter

Btw that sucks that some 810s won't do 133FSB! ,I thought those chipsets were spec'ed for 133!:disgust:
