Question about a G60JX CPU upgrade

[mat62]

Hi,

I'm planning to upgrade my G60JX i5-430m to an i7-720qm, but looking at pictures of these CPU's I've noticed that they are somewhat different.
Where the i5 has two small chips, the i7 has one big chip.

So my question is, are there any people here that did this upgrade too?
And, did they had to buy a new heatsink or is it possible to modify the old one? I'll hope someone can help me out. Thank you in advance.

hello mat62

you have pictures of these two CPU here!

i7-720QM (the Q3BA ES one - the second picture is an i7-820QM)
Intel Clarksfield Core i7 720QM Pic

Look here too:
I7-720QM Q3BA ES 1.6G 6M 1333 Intel Core i7 Mobile

i5-430M (SLBPN):
FS: Intel Core i5-430M 2.26Ghz

Here too:
I5-430M SLBPN 2.26G/3M/1066 Intel Core i5 Mobile

These two CPUs are Socket 988 (PGA988): 988-pin micro-FCPGA.

I think, I suppose the i7 can fit in your laptop, but beware about the heatsink: check the heatsink can be compatible with the different size die of the i7.

EDIT
Found this: look at this Asus website specs page for your model (UK site):

Processor & Cache Memory ....................... Intel® Core™ i7-720QM processor 1.60 GHz with Turbo Boost up to 2.8 GHz

so ^^

As you can see, the i7 TDP is slightly more important than the i5 TDP: but I guess you'll notice no heat difference nor increase in use (based on my experience: I've changed my P8600 CPU with 25W TDP to a T9900 with 35W TDP - and no heat increase).

The second chip on the i5 is the IGP which your laptop doesn't use so you can upgrade away if you want to.

Hi 0n1s4c and tijo,

Thanks for your answers. I'll give it a try and see if the heatsink will fit.
