Centrino: Is it pin compatable with a P4 mobo?

[HeXaDeCiMaL]

From reviews i've read I was lead to believe they were.

However my friend has got one via an ebay purchace on the cheep ;)

A 1.4Ghz Centrino(Banias) and according to what he's telling me there are 2 extra pins in one corner so the chip will not fit in the P4 socket...

Now he knows what he's doing with PC equipment, he gets thru more kit than me (which is no easy feat :o ) so I know he's not doing anything stupid...

Anyone got any ideas? or any links to info regarding using a Centrino in a P4 mobo...

cheers :)

I think Anandtech at one time posted a pic of a banias running on a P4 board, but I think it had been modded - whether they cut the pins or did something else I don't know. Maybe it's possible to lose those two pins :rolleyes:

i seen an adapter somewhere they used to bench a banias on a p4 mobo.

[althes]

That would be interesting if I could use it on p4 board.:D

I'd like to see how far it would overclock. Supposedly a 1.6 gig banias is about like a 2.4 gig P4.

isn't it funny when we talk about a 1.6 centrino performing like a 2.4ghz p4 its impressive yet when we talk about a 1.6ghz athlon comparing with it's intel equivalent we simply shrug it off as unimportant ;)

So true...

[gamefoo21]

its all because of the fact that intel made a cpu that does crazy amounts of work with a low clock speed... that upgrade path sorta died with the p4 lower ipc higher clock.

No it is not funny. A 1.6GHz XP has never been equivalent to a 2.4GHz PIV.The banias uses way less juice than a PIV or XP per performence. That is what makes the banias special. Also it has a IPC higher than the XP. The chip is simply amazing. The other thing special about it is that it can run at least on a the XEON server chipset. At least that is what the INC tells us. Yes the AMD cpu is unimportent to me simply because it is AMD. If I could get a opteron to run on my springdale platform then we may have something but that is not going to happen. The banias is a cross breed between the PIV and PIII with a little magic in between to make it happen. The CPU is already slated for use in blade servers. Intel has said itselves that the low voltage .09u versions will not require a HS even let alone a fan.

i never said the 1.6ghz amd was comparable to a 2.4ghz. if you will take the time to read what i said, i mentioned the AMD compared to it's rated rival.

its exactly the same thing and just because its amd and you don't like amd doesn't mean the situation does not exist.

xeon chipset? i can mod an XP to work in a Dual Athlon motherboard. we're still apples to apples so far.

who cares about them being used in blade servers? i don't run a blade server and i'm pretty sure you don't either.

Intel website states that the Intel Centrino technology is NOT a processor it is simply a mobile technology which allows Integrated wireless LAN capability, Extended battery life, and performance improvements which is achieved by using software prediction to eliminate CPU process replication... improvements are not seen in all applications.

Yes, I know.

Centrino is a brandname for the CPU, mobo, and onboard wireless network.

hence on my first post I wrote Centrino(Banias) as the (Banias) is the CPU. :rolleyes:

And the reason he bought it was it is intended to be a SETI/Folding rig, which the CPU absolutely rocks at.

Be good if you could gimmi some info on this m8 if u have any links or anything? or have any idea where u saw it?

thanks :)

Possible :D my friend managed to pull 3 pins out of his P4 2.4A and the CPU still works 100% and has been running overclocked in his server for a good year, 24hrs a day :D

If you get a pin-out diagram it would help. If they're simply a couple of extra ground pins it might be possible to remove them and get by. If they're required for signaling then it's not likely it would work.

I did and it was garbage.

why... thanks. :rolleyes:

It is DEFINETLY chipset compatible with the Pentium 4, look at this computer blade (http://www.momentum-computer.com/products/cheetah-a.html) server. It uses the E7501 and a Pentium M, anyone care to explain?

[gamefoo21]

that means it can go into a xeon board but does it do smp?

I can find any evidence disproving or proving SMP capability in the datasheet nor any mentions of SMP. I don't know how a xeon is told apart from a P4 but I wonder if the PM would show up as a XEON or P4.

[fafnir]

yep it IS pin compatible definitely,.... i saw a dude a month ago that had modded a asus 845 to use a centrino in and oc'ed the thing to 2.1ghz on air... beat down a 3.0C p4 on sciencemark and superpi... was funny to watch...

i think he said that the extra pins are used to control not only the speedstep, but also some kinda voltage switching control thing for the "deeper sleep" which is just garbage....

i can't remember, but i think he simply either cut them off or drilled some holes in his board socket...

btw, the cpu shows up as a "unknown processor"

the dude also hard modded the board to give only 1.3v vcore last i saw him, but apparently he blew *something* after a month of hard oc'ing and the thing just refuses to work...

and also the mobile adapter you're talking about is from powerleap.. dunno what its really gonna do for the centrino, but it *should* be fine....

[TC]

Doesn't really matter if it will work in smp because the xeon boards use a completely different socket than regular P4's.

[fafnir]

yah, maybe not socket 604 pin compatible... though it'd be funny if someone like powerleap came out with some adapter that could...
