[jesselsixer]

I am sure that this has been asked before. But I can not find it and the search isn't working.
I own a gateway P-7801u notebook and want to upgrade the cpu.
Which cpus can I put in it. Which one would prob be the best ugrade for the buck?
Thanks, Jesse

well i have a E8435 on my P7805 (it has the same speed) but it's way more cheaper (i bought it for 65 bucks) but you have to undervolt it as it gets hotter, but with good thermal paste and undervolt you can use it at full speed even at 100% load with no trouble at all

The E8435 lacks a lot of features, most of which is low power state stuff, but it also doesn't have Virtualization Technology, which I need... So it may not be for everyone.

Ok, I bought the x9100. Where can I find instructions on installing my new cpu?

There is a thread here that covers a complete disassemble: Gateway FX Disassembly Guide (Covers all 17in FX Notebooks) It covers getting to the CPU and removing the heat sink in the early steps.

All you need to do is remove the screws from the back and take off the cover. The heak sink will be sitting there, you need to unscrew it, then clean off the thermal paste from it. The CPU and north bridge are now exposed after removing the heat sink. You will need to clean the old thermal paste off of the north bridge.

I've never actually removed the CPU myself, but I believe that there is a small screw off to the left side of it, I think all you need to do is unscrew it a little and you should be able to pop the CPU out. Once you put the new one in you need to put thermal paste on it and the north bridge. Pretty much everyone on here swears by ICD 7. Its about ~$7.

Someone else here who has actually done a replacement can correct me on anything I'm wrong about and offer more advice.

these features mean nothing for the regular laptop user and as benchmarks show e8435 is just as fast as x9100 non-oc'ed

edit: I've checked in bios settings that e8435 does have virtualization option.

E8435 is intended as an Apple CPU.

yes it is and i don't think that the processor was widely used, so that's why many people don't know of it's existence
