sl510 can't upgrade cpu

Hi

i just got a second hand SL510

the model is 2875RG with T4400 and 2gb ram DDR3

 

i upgrade successfully the ram to 8GB (2x4) and also the DVDRW with a Blue Ray combo drive

 

BUT when i tried to upgrade the cpu to P8700 the laptop when i press the power button after a 3-4 sec power off

I also tried with another cpu P7450 but i got the same resolt

 

I install back the T4400

 

i have the latst firmware install

 

Finaly this laptop does not support 1066fsb cpu's?

 

Is anyone who have successfully upgrde the cpu on his SL510?

Betreff: sl510 can't upgrade cpu

after some research i find out that

 

the lenovo sl510 (2847) that have the P8700 cpu use the GM45 chipset that support 1066fsb and it have the 4500MHD gpu

 

my sl510  (2875) use the older GL40 chipset that support 800fsb and have the 4500M gpu

 

so i gess the fastes cpu that i can upgrade my lenovo is the T9500 (2.6/6M/800)

 

(But both model have tha same bios firmware)

I've made the following upgrades:

Everything runs great. Hope this helps with your question or anyone else who might be wondering what upgrades they can do.

Re: sl510 can't upgrade cpu

I do upgrade my cpu T6670 with T9400 thats works fine for me. but I didn't upgrade my ram,  which is my next plan. i have a ATI Mobility Radeon HD 4500/5100 series. and i am looking for a cheap Intel Core i7-620M cpu. its listed in supported Processors.

Re: sl510 can't upgrade cpu

I was able to upgrade cpu all the way to Intel Core Duo T9900 3GHz processor. I think this the highest you could go to.
