p-7801u cpu upgrade

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

Thanks, I appreciate it.
I ordered one just now!

 

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: http://forum.notebookreview.com/gat...embly-guide-covers-all-17in-fx-notebooks.html 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

 

So for someone such as myself who is not planning on O/C'ing, is the E8435 a possible solution to simply get the 30ish percent increase in processor speed? Has anyone tried this and if so how has the heat issue been? Are the E8435 E0 vs C0 issues about the same as the x9100's (heat etc)?

Due to this being intended for mac use, are there other changes that need made to the notebook (BIOS etc) to install it? I've been thinking that to upgrade my processor I just pop it in and go?

I'd love to know what you all would consider good cpu upgrade options for someone not O/C'ing (besides the x9100 E0 and the E8435)?

 

I've never seen or even heard of an E8435 e0 version but I had a chance to compare E8335 e0 and E8435 c0 and though the last one is supposed to be a bit faster and windows perfomance index confirmed that by showing 0.1 point gain (6.6 vs 6.5) but the real experience showed opposite results. E8335 worked with outstanding perfomance and I didn't even have to pay attention to the temps while e8435 had to be undervolted otherwise it would just throttle. So if there's a good priced E8335 e0 I'd suggest you to turn your attention to it instead of E8435. But it's always about money so if there's real cheap e8435 that would be a good choice too and the only thing you need to take care is to undervolt it with throttlestop utility.
And you don't have to do anything with bios, these cpu's are fully compatible with p78xx and p79xx laptops.
Hope this helps))

 

Thanks for the input!! I'll have to look into them both. I have seen a couple of these that were fairly inexpensive and while I would love to have the option to overclock, I seriously doubt I will ever do it.

I saw the E0 listed in the graphic TANWare put in his post on page one. It lists for chips:
Core 2 Duo E8335
SLAQC (C0) 44W
SLGEB (E0) 35W (This one running a speed of 2.93 compared to the 2.6 on the C0)

Core 2 Duo E8435
SLAQD (C0) 55W
SLGEA (E0) 44W

I know that heat is not always correlated with the watt of the cpu but I would think that lower wattage is probably better. (Or I may just be very weary of possibly killing my MB lol).

I also found another thread about the whole issue (Noobe Help: Gateway® P-7805u FX Edition upgrade to X9100) and am going to look into the T9800 and T9900 as well.

 

here's the complete list of c2d cpu's List of Intel Core 2 microprocessors - Wikipedia, the free encyclopedia

that e8335 e0 (tdp 35w) I was talking about was the same as t9800 but for less money!
but as I told you I was also using e8435 c0 (tdp 55w) and I can tell you for sure there's no threat of burning the mb.

 

Wondering if anyone who bought an x9100 from this seller had a good experience? Where did your stuff ship from and did it take forever to get it?

 

Not from him although it seems the items primarilly ship from china.
