Acer 4820TG - change cpu..

Hi! Just wounder If it´s possible to change the cpu to something else that´s better than the I7 640M ??

Anyone selling a I5 or I3 that it clockable?

Is it possible to fit a regular intel cpu ??

Please give me as much info as possible!

 

The Core i7-640M is basically a high-clocked Core i5 since it is a dual-core processor with Turbo Boost. I don't see why you would want to downgrade to a Core i3/i5.

You cannot use a regular desktop Intel CPU in the 4820TG laptop.

I would stay with the Core i7-640M.

 

Since Abo on setfsb didn´t had time to help me find the right clockgen I´m thinking of downgrading to a clockable i5/i3 istead and clock it faster than the I7

 

The Core i7-640M is clocked at 2.8GHz and it Turbo Boosts to 3.46GHz. You don't need to overclock; it's already extremely fast.

 

No such thing AFAIK.

 

That's kinda sick, how could you not be satisfied with a 3.46GHz i7

 

The clockgen is separate from the CPU and it, not the CPU, is responsible for compatability with the SetFSB program. If you haven't found it on the mainboard, you're not likely to get any better results with an I5. The best you will do with an I3 is 3.2 ghz. The I5-580M has clocked up to 3.8 ghz but that was on a device that had a clockgen that worked with the optimal G73 clockgen. I think you're stuck with the I7-640M as your top speed. Time to trade up to Sandybridge? SB units should be released over the next couple of weeks. Maybe you can get a 14" Lenovo E420 with an HD 6630 and a Quad SB processor. OC that baby!

If you want better than i7-640M, may I suggest i7 extreme edition processor? You can adjust it to run faster with ThrottleStop.

 

I would not recommend buying an Extreme Edition Core i7 mobile processor for the 4820TG laptop.

First of all, the Core i7-640M is a dual-core processor; not a quad-core processor. A quad-core Core i7 (TDP 55W) would run much hotter than the dual-core Core i7 (TDP 35W). The Core i7-640M already reach temperatures in the high 90s Celsius, which is very close to the Core i7-640M TJunction of 105C in the 4820TG laptop.

There are only 2 Extreme Edition Core i7 processors with the same socket as the 4820TG laptop (i7-940XM & i7-920XM) and both of these processors have a lower TJunction of 100C, while running hotter than the Core i7-640M. The 4820TG laptop "only" has 1 air vent and this will not be efficient enough to cool down the Extreme Edition Core i7 processor. In result, this would cause CPU throttling and massive heat build up in the laptop.

Most importantly, the 4820TG BIOS needs to support the Extreme Edition Core i7 processor for it to work.

 

I never said i7-640M is a quad-core processor.

Yes, I'm aware it require 20W more for i7 extreme edition processor. i7-640M reaching 90C?!! Wow that is too high for dual-core processor. Even my quad-core doesn't reached 90C when running extensive task (without cooling pad of course). I checked 4820TG heatsink & I found out it doesn't look like it design for quad-core processor though. However, for those who still want to upgrade to quad-core extreme processor, they will need to mod 4820TG's stock heatsink with copper shim & re-apply thermal paste with better one. There are several example, different acer models of course, people upgraded from i5 to i7 quad-core (standard/extreme).

Yes it is true. I'm right now checking 4820TG's BIOS to learn what/which processor it does supported.

 

I have a 430M i5 on a 4820TG. Does anybody know if i can upgrade it to something with aes-ni?

You can but there are hardly any CPUs that support it in this line.
I bought a Core i5 560M which does (not in the same laptop though- I use 5740G) and the performance is awesome. My whole data partition is encrypted

 

I intend to encrypt all my system on LVM2 with luks. It's a pity /boot remains unencrypted....

Do you know what socket should i search for? I found 3 CPUs with 35W that have aes-ni.

 

It's rPGA988.

 

I've found these:
Compare Intel® Products

Last 4 have improved VTd and aes-ni.

 

You can use any of the 4 CPUs.

 

Agreed- all 4 will work but I'd concentrate on 560 or 580- while all support AES-NI you'd certainly want as much of an upgrade over 430M as you can- provided that you're about to spend some decent money on CPU anyway.

 

Any of the I5-520M CPUs or higher have the AES support. I use an I5-540M. I would get the I5-580M if you can. It depends on how much less the I5-520M or 540M cost. If you can get them $100 less, I would consider it.
