Hp dv6-3180SP Exchange CPU and Heatsink

[ers49_k]

Hi,

I have two questions.

First one,

I have an HP DV6-3180SP and i want to upgrade my processor. My current processor is:

Intel Core i5-460M processor with 2.53 GHz, SC turbo up to 2.8 GHz, Dual 35 W

In the maintnance manual, spare parts, it is listed some dual core processors and some quad core processors. Can i upgrade to an quad core processor, like:

Intel Core i7-820QM processor with 1.73 GHz, SC turbo up to 3.06 GHz, Quad 45 W

Second question,

Since the quad core needs to dissipate 45w instead of 35, the Heatsink 604787-001 is an possible upgrade from the 603691-001.

Thanks in advance

P.S.: Sorry for my english

Here is the Service Manual:

Manual

To figure out what processors will work on your motherboard we have to look at the choices of motherboard. See pages 22-23. Notice how motherboards specify dual or quad core? That means you cannot put a Quad on a Dual motherboard. 

So no your top choice is an i5-580M which runs at very slightly higher speed as yours. Not worth it in my opinion.

And what about the heatsink? Can i exchange the 604787-001 with 603691-001?

No its the Quad and Dual thing again. The Quads are 45W and need a different heatsink. The hole pattern is not going to be compatible so the fan/heatsink for the Quad boards (and 45W CPUs) will not bolt onto your Dual (35W) motherboard.

I don't want to be ungrateful, but are you sure? They look the same, apart the extention on the cpu.

To be 100% sure I would need to see them next to each other but if they were identical why the need for 2 part numbers? 

There is not generally a heatsink "upgrade" and you use the one specified for the system. I am not sure how you think the 45w heatsink would be better. I am sure it uses the same fan that moves the same amount of air and has the same cooling capacity. 

I went to google image and looked at a closeup on both parts and it is really hard to tell if the mounting hole pattern is the same, but it very well might be. The 45w has an extension as you say. I am not sure if that would fit on the dual core board. Nobody is going to be able to give you any better information because nobody has forseen that somebody would try to put the 45w heatsink onto a board made for 35w processors. About all you can do is try it and see if it works.
