I bought a second hand M57-6089W2e recently. It has E2140 CPU. I wish to upgrade this to a higher speed/spec CPU.
Does anyone know what CPU this Think Centre would take?
It is running on XP has only 512MB RAM but I have already ordered 2x2GB RAM from Crucial and they are on their way. Hope this itself will make it fast. But I think upgrading the CPU would be even better.
Will it take the E5200-E5800 series CPUs?
Willl take E6600?
Will it take the Core2Duo CPUs like E7500 and upwards?
Help from knowledgeable persons from Lenovo or someone who has actually upgraded the CPU will be highly appreciated.
This is a very quiet PC and I like it - just want to make it faster and faster!

Hi and thanks.
Following some old threads on the forum I also found a long list of CPUs in the System Parts List for M57-6089.
However I have a few questions:
1. The list gives CPUs that run at 800 MHz as well as 1066 MHz. I think my present M57 runs at 800 MHz FSB.
2. Does it mean that I can only upgrade to those CPUs that will run only with 800 MHz ?
3. How would the motherboard change the mutiplier automatically to suit the new GHz frequency of the CPU? I do not see any settings for that in the BIOS.
4. If the motherboard will recognise the new CPU correctly and automatically change the multiplier, can I then also use the CPUs with 1066 MHz FSB?
5 Can I just pop in the new CPU in place of the old one or do I have to do anything else?

Thank you so much for your prompt reply!
This list also gives Q6600 & Q6700 running at FSB of 1066. These are with Quad core. Will they also work?
What about CPUs with 1333 MHz FSB? Will they also run? But I guess these would be expensive.
Of course, I do not want to spend a lot of money.
There is E5500 2.80 GHz 800 MHz FSB, but it is not listed. Due to higher power consumption? Will it work?
There is E6600 for GBP 60.
The performance scores on one website are:
E2140: 907, E5500: 1906, E6600: 1503.
If these are correct, wonder if it is worth spending GBP 60 to get a 66% increase in speed.
Also what about higher power consumtpion? Will the heat sink in my M57 provided for E2140 cool the faster CPUs sufficiently?
The applications are mainly for office and Internet (no gaming!).
Hopefully shall get the 4GB RAM today. This itself should speed up the E2140.
What do you think?

I think you are right, no point in upgrading for the sake of upgrading.
Feel with 4GB RAM E2140 should be OK.
Incidentally, I think the E5500 & E6600 that I mentioned as available for a price of GBP 50 - 60 are actually Pentium Dual Core CPUs and not Core 2 Duo. These run at 2.80 & 3.06 GHz respectively as against the Core Duo E6600 that runs at 2.40 GHz. I read also that these Pentium Dual core actually have two cores side by side, but the Core 2 Duo is a new architecture. Although the E2140 is called Pentium Dual Core, its architecture is that of Core 2 Duo and these were released first as a low end Core 2 duo. Of course, as you seem to be the expert, you should be knowing this.
So, I am not going to try the Pentium D E5500 or E6600.
Thanks again for your help.
Shall let you know how the M57 with E2140 behaves with 4GB RAM.

Intel have changed the naming systems to refer the Core 2 Duo to the Pentium Dual Core systems.
Pentium D is a different CPU class, it is basically a dual core Pentium 4 CPU, and you shouldn't get them because they use lot of power to produce performances lower than the E2140 in many cases.
So basically all Exxxx CPU are Core cpu, rather than the Netburst Pentium 4 CPU (which is what Pentium D are).
Intel is using the Pentium Dual Core to make their old CPU unappealing to consumers with little to moderate computer knowledge, as they want people to buy the i3, i5 and i7 CPU. So lot of people when they hear or see the name Pentium Dual Core CPU, they would think it is a superseded cpu from those Pentium 4 days.
P.S. you can just google the Exxxx CPU, there are tonnes of information available on the net.

Hi Thanks again!
I got just now the 4GB RAM I had ordered for the M57.
Installed and it made a world of difference.
The M57 is now very fast. Much faster than my main 5 year old PC that is running with P4 @ 3.04 GHz.
I am going to change the main PC to a DELL Vostro 430 with i7-860 CPU ...
So, am going to use the M57 as a back up and also my wife will use this mainly for Internet, email etc.
I don't think I shall try and upgrade the E2140 CPU in it unless I can get a higher performance Core 2 Due from the list cheap (< GBP 50)!
Thanks again for your interest and help.
