G550 upgrade

Hi,

 

can i upgrade my G550 laptop with Intel Core 2 Duo T9500?

http://ark.intel.com/products/33918/Intel-Core2-Duo-Processor-T9500-%286M-Cache-2_60-GHz-800-MHz-FSB...

 

Now i have pentium dual-core T4400:

Also i am interested in Intel Core 2 Duo T9900, but ut is 1066MHz FSB and i can not change fsb from BIOS.

 

I think it should be notable, that it is GL40 inside.

 

Thanks

G550 CPU Support?

Hi,

 

Has anyone upgraded their G550 CPU?  I just wonder what it would be capable of going to someday when it is out of warranty.  It says it has a GL40 chipset and I've read conflicting info on whether this will support 1066FSB.  Still, on the spec sheet it shows 1066 FSB processors:

Has anyone tried it?

 

Thanks,

 

Alan

I have not tried it. This site http://www.pricewatch.com/gallery/cpu/core_2_duo_mobile seems to have cheap P7550 chips from time to time.

I have tried intels T9400 and it didn't boot up. Shame on Lenovo they don't say on they products or BIOS updates what processors they support.  At least access is good

Hello,

 

 

Don't upgrade. To upgrade get a new high end laptop with quad core Intel.

Re: G550 upgrade

According to Lenovo PSREF @ http://www.lenovo.com/psref/pdf/3wbook.pdf

T4500, T6500, T6600.

 

In other words, these were the faster cpus

that Lenovo included with you model using the GL40.

 

Others may be compatible, but certainly NOT any 1066 bus.

 

CPUZ is good, Intel also has a good chipset detection util.
