Sony Vaio VGN-FS Processor upgrade.

Is it possible to upgrade my standard 1.73GHz Celeron M?

If so to what models? Would a Pentium M be compatible?

Thanks.

 

Wow this one is tough do you know which 1.73 Celeron M you have? tThere are apparently three 1.73GHz Celeron M available, the 430 and the TWO 530. According to Wikipedia the 430 is Socket M and the 530 comes in a Socket M AND a Socket P variant.

In both cases you will be able to upgrade to a C2D (assuming you have an appropriate BIOS), but specifically which C2D models are dependent on the socket.

 

Check your processor bus speed. If it's 400 Mhz, then you can upgrade to 2.0GHz. If it's 533 MHz then you can upgrade to 2.26GHz. You should either be using a Intel 915GM or 915PM motherboard chipset.

Intel Centrino 760 is the 2.0GHz model.
Intel Centrino 780 is the 2.26GHz model.

 

Centrino is not a CPU it is a brand name for platforms (many) that have certain CPU's, chipsets and wireless cards.

 

All 1.73GHz mobile Celerons have a 533MHz FSB:

As Powerpack said, Centrino is the name of the platform, not the processor. There is no such thing as a Celeron 760 or 780.

If you're talking about the Pentium M 760 and 780 they are both for Socket 479, not M or P.

 

my bad. have forgotten the names and such but i do remember when i was upgrading my VAIO FS that i had to check the bus speed before purchasing the CPU.

 

Thanks for the replys. Am I right in thinking I might be able to use a C2D ?

My exact spec according to the intel CPU identification program are:

Intel Celeron M 390 1700MHz 400MHz FSB 1MB Cache.

Thanks again!

 

It changes things now that you say you have a Celeron 390 (as opposed to a 1.73GHz Celeron you mentioned in the first post).

The Celeron 390 is made for Socket 479. Subsequently you won't be able to use a C2D; the best chips you'll be able to get are Pentium M. Specifically the Pentium M 765. There is a small chance you'll be able to use the faster 533MHz FSB 770 or 780 but I wouldn't bank on it.

 

Hmm sorry I thought it was 1.73.

I have found some S479 C2D's - http://www.ebuyer.com/product/133064/show_product_specifications

Would sucha processor not be compatible, if so - why?

 

T7250 is Socket P.

http://en.wikipedia.org/wiki/List_of_Intel_Core_2_microprocessors

The mobile socket nomenclature is confusing because Socket 479, M and P all have 479 pins.

To clarify, Socket 479 is made for Pentium M and related Celerons. Socket M supports Core Solo, Core Duo, early Core 2 Duo and related Celerons. Socket P only supports C2D and related Celerons.

 

Ok so any socket 479 M are compatible .
What would you recommend?

 

That's honestly tough to say...

I'm reasonably sure that the P-M 765 is the best chip you can get here. But the thing is I don't think it will offer a great increase in performance over the Celeron. I do believe that both are based on the same core (Dothan)... with the P-M you'll get twice the L2 cache and SpeedStep... but for at about $200USD.

Whether this (what I believe to be) small performance boost is worth $200 is up to you.

 

Hmm I'll leave it, unless I can get a cheapy off eBay.
Thanks for all your help.

 

Well I found this

http://cgi.ebay.co.uk/Intel-Pentium...goryZ177QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Its a Pentium M 478 Pin, so technically it should work?

Can you verify this. Thanks again.

 

That's an Intel Pentium 4 Mobile, not a Pentium-M.

Look out for processor numbers starting with 7.

 

Right... This is very confusing
So why wont that work? It has the right number of pins.

 

Any more help?

 

Moon Angel is correct, the ebay chip is a P4-M. It uses (yet again) the same pin count, but is labelled as Socket 478. It is mechanically and electronically incompatible to Socket 479.

You can ONLY use 400MHz (and doubtfully 533MHz) Pentium M. You cannot use P4-M and you cannot use Core chips.

Besides, the 3.2GHz P4-M is almost certainly inferior to your current Celeron M.

 

But surely 3.2 is better than 1.7

Sorry i'm really quite a n00b when it comes to latop upgrades...

So really I want to try and get the best Socket 479-M Celeron ?

 

But that's 3.2 on a NetBurst core as opposed to 1.7 on a P6M/Dothan core.

And you already have the best Socket 479 Celeron.

The only faster compatible chips are the Pentium M 735, 745, 755, 765 and MAYBE the 725 (I omitted the 533MHz FSB chips because I don't think they are compatible). All of them should provide a bit of power saving though, since SpeedStep is disabled on Celerons.

 

Thanks. I'll keep an eye out for them

 

hi i have a sony vaio vgn fs7400w processor is 1.73ghz pentium m. and am looking to upgrade my processor but dont know what the options are. also i have a 160gb harddrive is that upgradable to?
