Core 2 Quad 1066 in 800MHz Laptop

[Obnoxious]

Hey all!

Thank you for taking your time to read this, I sincerely appreciate your support. I just have a question, which may sound ridiculous, but I think it's worth a shot. 😉

My father has an old laptop which runs slow. I'm going to upgrade the RAM soon to 4GB (maximum), but the CPU is what is making the laptop run slow. At the moment it has a Pentium Dual Core T4400 Mobile, which is on Socket P (478-pin) @ 800MHz.

I was thinking, would a Core 2 Quad work on the laptop? The recommended watts do not match however, nor does the FSB transfer rate. The laptop current's processor is at 35 watts, whereas the C2Q requires 45 watts. The socket is the same however.

The FSB is different, which is no major issue. I'm willing to run the CPU at 800MHz, rather than 1066; if I know if it works. The C2Q I'm looking at is the Q9000.

I'm wondering would this CPU fit in my father's laptop?

Sorry about the trouble, and I do sincerely appreciate the support. Thank you! 😀

I highly doubt that CPU even comes out, it's most likely soldered into the board.

So no, don't even try unless you are 100% sure that the Laptop supports CPU swapping. They are generally built proprietary.

No, the CPU can be purchased separately and my laptop can have it's CPU replaced (already upgraded it to the Pentium from a Celeron 2 years ago).

Does the BIOS allow you adjust the FSB and Multiplier? The Core 2 quads are generally not backwards compatible with older hardware. They needed boards that were specific to them.

If the Motherboard doesn't support that chip, you are risking some serious damage to both.

Highly not recommended. High end Core 2 Dual at the same voltage is the last choice, IMHO. Otherwise; view the manual and confirm if it's supported and update the BIOS first.

You already know how to replace the CPU, but you need to look up the CPU support for that specific laptop motherboard. Sometimes a different revision on the same model has different CPU support because those generally are not intended to be upgraded. If your motherboard doesn't support it then it won't POST even if it fits and should work. Since the C2Q use more power if it does work make sure that you don't need to upgrade the cooling assembly as well least it overheat. You can find the service manual for your laptop motherboard if you look hard enough.

Thank you very much for your responses Alec Mowat and megamanx00; I sincerely appreciate them and have been greatly informative.

Unfortunately the BIOS doesn't allow the adjusting of the FSB or multiplier, and I was willing to run the Core 2 Quad at a lower frequency to benefit from the quad cores, L2 cache and SSE4.1. Running it at 800MHz, I was also expecting it would require less volts/watts, and also produce less heat.

However, the Core 2 Quad Q9000 was introduced in 2008, my father purchased the laptop at the end of 2010; so I was not sure of the compatibility, but since the motherboard operates at 800MHz, I'm now going to assume it's not compatible based on the responses. Perhaps the motherboard predates 2008, the introduction year of the C2Q on socket P.

Since my father's laptop is old, I think I'd be safer upgrading it to a Core 2 Duo T9300; which was my original plan and should be compatible (same FSB, socket, and power consumption requirement).

I was just asking this question to find out if I could place a better CPU in my father's laptop. Again, thank you for your responses and I think I'll go for a Core 2 Duo.

Thank you again for your efforts!

With Megaman.

Check the manual and verify if it's supported or not. If the motherboard officially supports the chip, it should change it's owns settings on recognition. If you can't confirm 100%, not worth the experiment.

what model laptop is it ... thats a must know stipulation to actually identify if it would work or not as i have the same config on mine and running windows 10 now on it with the pentium t4500 model
