Upgrading PC CPU

I want to upgrade the original CPU in my Gateway #450 desktop PC. I've replaced the hard drive and modem several times and I know how to take apart and reassemble a PC. The CPU that's in the PC is still the original one and it's very slow by today's standards. Is there a current one that will fit that model? If so, can I get it from Fixya?

Re: upgrading PC CPU

Put in as much RAM as you can afford. I've found that this is the quickest, easiest way to speed up a computer.

Re: upgrading PC CPU

I bought a Gateway 450 mini tower, circa 1998 approx.. It had belonged to a local company and it was minimal, 8.4 GB hard drive, 64 RAM, it ran 98 se and I'll admit it ran pretty good.
Being a hobbyist, I just had to find out what she'd do, how far could I push her and still perform.
I replace the Ram with 2 -128 for a total of 256 MB. I put in a 40 GB hard drive and installed XP Pro., expanded the virtual memory a bit.
It was Great.
Then I replaced the telephone NIC card with a DSL NIC card and she goes on-line. Not bad I thought, but it only had a CD-ROM and a Floppy drive. I dug into my parts closet and found an USB card and installed it.
Now, my little 24 year old beauty can receive info four different ways, uses the DSL and is much faster.
Now...after a year or so, I want to keep up grading as much as the mobo will let me get away with.
Does any one know if this two memory slot board will take maybe up to 500 MB or even a full Gig?
I'd love to install a DVD drive that I could play movies on.
This little unit brighten up my day when all these up grade parts worked.
An amazing little machine and if I could, I'd up the processor.
So let's hear it from you hard core hobbyists, please share your knowledge and help me turn this retiree a contender again.

Re: upgrading PC CPU

Where the cpu sits on the motherboard there will be 3numbers on the cpu holder which is white and it will tell you what socket it is ie pga370 socket a etc then if you still have the original motherboard manual it will tell you what speed cpu your motherboard will take!

Hello, I'd like to know what compatible cpu upgrades are available for this laptop. Thanks

in laptop the only best way to upgrade is only the RAM/memory and hard drive/hard disk....because if you want to upgrade the cpu it self is not possible for the old laptop because of the new pin slot that is available in the market....and only the expert/certified technician can do this...

Toshiba Satellite C655D-S5084 CPU upgrade

It is possible but usually not worth the hassle.
Changing to another CPU chip that fits your motherboard may only show a 3-10% performance change.

See videos of CPU replacement in laptops like yours:

In general, you are better off adding more RAM (memory) or replacing the hard drive with a faster SSD (Solid State Drive) to make a laptop "fly". Your laptop can hold a max of 8 GB RAM:

In MOST laptops, slower 5400 RPM drives are used, and this is the main performance bottleneck. A 7200 RPM drive or (better yet) a SSD drive will help matters, as will more RAM (the most cost-effective speed increase).

Gateway 450ROG cpu upgrade

This computer is ancient. You could buy a refurbished computer for $80 and it would still be at least 4 times better than this computer. Just buy a new computer.

That unit it about 10 years old.
Unfortunately, you cannot upgrade the CPU (processor)

The RAM is a standard 100MHz non-parity SDRAM SODIMM. The 2645 can use 128MB DIMMS for 160MB maximum. It has 32MB internal and two slots.

The hard drive size is limited by the BIOS. Any standard 2.5" hard drive should work, but may show as limited size, maybe 20GB.

Get a PCMCIA modem.

If you found a docking station for this unit, you'd be in better shape. Like I said, it's 10 years old. It won't be easy.

Laptop running hot - Fan cycling on and off every 10-20 seconds

My guess is that CPU fan, it there is one, is not working properly and your computer is heating up. Is it turning off, too, occasionally after a period of time? Suggest a new CPU fan.

Suitable graphics card which would enable me to play games

The problem is that you can't just Upgrade the video card in a portable like you can a desktop system.

Upgrading the video would require a new motherboard with discrete graphics. VERY few portable system have upgradeable video without major cost (Usually cheaper to sell system and buy one configured as you need it) which is my recommendation if that system will not perform as you desire.

Generally, upgrades on portrable systems are limited to MEMORY, HARD DRIVES and plug in components like wireless cards, modems etc.

Central processing unit for Gateway computer

For a couple of hundred dollars you can get a much faster bare-bones desktop or tower and mb cpu combination and move your hardware to it. Upgrading your 450 isn't worth the trouble though jumpers on the board should handle upgrades to maybe 600MHz.

I want to know if I can upgrade the harddrive and memory

Depending on the memory you already have you can install upto a maximum of 1GB 266MHZ DDR, and cannot see any reason for not being able to upgrade your hardrive for a bigger one, but be aware that the Operating system backup will probably be on a seperate partition on your current hardrive, unless you got an installation cd with your laptop.
