What would be a compatible cpu upgrade for the 600is

Please note that CPU upgrades in notebooks/laptops/netbooks are highly problematic because they depend on often uncertain motherboard specifications (different notebook models bearing the same series number in your question can have different internal and external specification and be based on different motherboards).

The most serious problem you face is that CPU upgrades in laptops/notebooks/netbooks inevitably require near complete disassembly and the correct reassembly of the computer. Inevitably, this type of work is best done by an experienced professional, trained for and capable of performing a warrantied repair. Understandably, the associated labor costs will be on the high side.

Also, upgrading the CPU requires the user to first risk expenditure on an item that cannot be returned to the seller or supplier if later found to be incompatible but could still be a potentially expensive replacement product, without being absolutely certain that is compatible with the motherboard for which it is intended.

So you will need to do extensive research on the specification of the precise motherboard of the precise model of your notebook. To do this, you will need the full, long, specific model number plus also the Serial Number (S/N) and Part Number (P/N) of the computer that are usually printed on a label underneath the computer. From these, you should obtain the P/N of the motherboard, then navigate to the support and product information pages of the motherboard manufacturer's website to verify the CPU compatibility specifications of the motherboard and then proceed from there.

Intel Pentium Mobile processor T4200 (1 MB L2 cache, 2 GHz, 800 MHz FSB, 35 W), or T3400 (1 MB L2 Cache, 2.16 GHz, 667 MHz FSB, 35 W), supporting Intel 64 architecture


Your notebook features the above Central Processing Unit (CPU) in its standard specification, according to Acer. This CPU is commonly referred to as a Dual Core / Intel Pentium M / 2.2GHz / 64 Bit Processor. This type and Model of Processor is outdated and the upgrade options available to you are limited.

The indications are that your best course of action would be to back up any important data stored on this notebook's Hard Disk Drive (HDD), restore the notebook to Factory Settings, sell it on eBay or CraigsList or any similar website popular, in your geographical location, for the buying and selling of Used Consumer Goods and then put any sale income raised towards a new, state-of-the-art notebook capable of performing the function(s) in which the current notebook is disappointing you and steering you towards radical thoughts such as CPU upgrades.

At the very least, consider several or all of the far easier, far cheaper and far less labor-intensive and labor-expensive upgrade options to improve the power, speed and performance of this notebook before contemplating a CPU Upgrade, such as, a Maximum Capacity RAM Upgrade, an Operating System (O/S) Upgrade, upgrading to a higher performance, higher Spin Speed and/or higher capacity HDD or newer technology Solid State Drive (SSD).

Yes a USB 2.0 PCI adapter card but Ethernet at a 100 megs is better than USB at 21megs.

cpu speed has nothing to do with ram. they are completely independant. ram speed is important to the FSB (front serial bus) this is the speed at which your motherboard communicates with the devives attached to it. cpu speed refers to how fast a cpu can process info. or how fast it "thinks". most motherboards have the capability of upgrading cpu's. your mobo (motherboard will support the following cpu's:
any pentium 4 up to 3.0 ghz
it supports the following ram
ddr (nott ddr 2 or 3) up to 2 gigs (1 gig each slot) of 533mhz speed (or less)
it also supports up to 2 gigs of sdram either pc133 or pc100
you are using 400 speed ram as you stated i would upgrade to a 533 speed ram as it will be faster, but this is not necessary. as for the cpu just get any P4 (pentium 4) that is 3.0 ghz or less and it will work.

Upgrading the CPU in a notebook is a bad idea.

Even if you get a compatible CPU, a faster processor means more heat, and notebooks are not design to handle it. You would risk major damage.

If you want to make it faster, try increasing the memory.


Good luck!

Ok i checked the ASUS website and looked up the CPU compatibility list for your board here:
http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us

But unfortunately that particular CPU doesn’t seem to be supported. Must be something to do with the technology inside the CPU or the amount of L2 cache or something like that. (it would require some rather intensive research to find out exact reason why...

And when searching for ASUS motherboards that are compatible with that CPU it comes up with this short list;

AP120-E1
AP130-E1
PSCHL009
AP140R-E1
P4RD1-MX

Did you clear the cmos when installing the new cpu before powering it up?

i know the CPU you have now runs at 400FSB and the new one runs at 800FSB But that board supports both speeds so that shouldn’t be a problem.

What type of RAM do you have ?
maybe check owners manual for memory compatibility chart for new 800FSB CPU

Have you tried the latest beta bios from ASUS site :
I can not guarantee that it will work but it is worth a try.

NOTE: Updating the bios can be risky and should only be done to resolve compatibility issues or things like that (or to add CPU support) In the rare event of a power failure during bios update your motherboard could become permanently unusable. (Always use a brand new floppy and follow the instructions to the letter when updating system bios)

Sounds like the processor you're trying to upgrade to isn't the same frequency. The processor, motherboard, and memory have a matched frequency. For example; a motherboard with a frequency of say PC4200 will only accept a processor and memory of a PC4200 frequency. If you try to use PC5300 memory it basically won't do anything, blank screen, or maybe a beep. The same if you tried to use a processor with PC5300 on the PC4200 board. The best way to find the frequency rating is to look on the memory. They class the memory by frequency, but rarely ever list the frequency for the board or processor. Research the new processor to find out the memory class and then see if it matches the memory in your machine. If it doesn't then the processor won't work. If it does, then new processor may not be compatible, and that means more research.

if you are looking for performance, you may want to start with the RAM first. It is DDR2 and that laptop is able to go up to a max of 4GB RAM. If that doesn't speed things up, consider getting a 7200RPM hard drive. Laptop processors rather difficult to upgrade. It will require disassembling the laptop completely and theres a good chance that something will be damaged in the process

Here is a link to the manual for the motherboard.
http://dlcdnet.asus.com/pub/ASUS/mb/sock423/850/
p4t-m/p4tm-100.pdf

The manual doesn't really say what cpu speeds the board supports.
1.4 ghz was about the fastest processor speed when the board came out. My guess is that a 2.0 ghz cpu may not work.
It would be a slight improvement over the 1.4 ghz cpu, but not a huge difference.

Depends on you mainboard and the cpu speeds it supports.

Upgrading is quite simple, this guide is a bit outdated as cpu's go
but the basics are still the same. Just open up your computer,
push aside all wiring, remove the cpu cooler/fan assembly, remove the cpu, insert the new cpu with the correct amount of cooling paste and gently insert the new cpu, reseat the cooler/fan and your done.

boot it up to BIOS screen now and look at CPU settings. It may tell you the maximum speed.
