What processor do I need for my PC?

Specs: Windows XP, SP2, AMD Duron 1.1ghz, 632mb R

Hi guys, can you help?

I want to upgrade my computer's processor, because the other one is just a little bit too slow for me. Don't get me wrong, i'm not exactly a 'heavy' user but I still like things to run at a reasonable speed!

I'd like to know what the fastest processor is that my computer will support and where the best place to buy online is. Ebay if need be! Unfortunately i'm not a technical whizz so i don't have a clue how to find out which processors will work. I don't even know the difference beween AMD Duron and AMD Athlon, which is why I can't afford to just buy one without researching first. If I post my system info below could anyone with some spare time and a brain for hardware help me decide? Thanks!

Current processor: AMD Duron 1.1ghz

BIOS: Jetway - 42302e32 Award Modular BIOS v.6.00PGN, 07/24/02

If you need any other information please let me know! Once again, a million thanks for your help.

Model of the Motherboard??........if you know that you can go to:


..and look up CPU support and wether or not you need a BIOS upgrade

Well, it would help to know your motherboard manufactuer so I can find out your Processor Socket.


P.S The difference between Duron and Athlon. Nothing. Absolutley Nothing. The Athlon is more expensive and runs at a higher clock speed and bus rate, which I don't expect you to understand, but now you can act like a computer nerd :)

"The difference between Duron and Athlon. Nothing. Absolutley Nothing"

Wrong. Absolutely WRONG! If you don't know the answer to the question, don't answer it!

The early Athlon (Tbird core) ran at either 100MHz (200FSB) or 133MHz (266FSB)...the early Duron (Spitfire core) ran at 100MHz (200FSB) only! There is also a Morgan core Duron that runs at 100MHz (200FSB) only. The early Athlon has 256k L2 cache. The Duron has only 64k L2 cache. The latest version on the Duron (Applebred core) runs at 133MHz (266FSB) but still has only has 64k L2 cache.

The Duron is a lower performance "budget" CPU. It is only available in the socket A.


We'd need to know the model number of your board, the info you provided doesn't help other than it tells us it's a Jetway. Try using CPUZ & check the mainboard tab:


Asus A7N8X-X
1800+ @ 8.5 x 200MHz
768MB PC3200 2.5-3-3-7
Asus A9550GE/TD 128MB
WinME/WinXP Pro

Hi guys, thanks for the kind responses. How anyone can know so much about computers is totally beyond me, it's all I can do to install a printer! I've used CPUZ and it gives the following information:

Mainboard: SiS 730
Chipset: SiS 730 Rev: 02
Southbridge: SiS ID0008
Sensor: Winbond W83697HF

Does this help at all?

That narrows it down, but I'm surprised it doesn't give an actual model number. It appears that you have a Jetway 830CH/830CF, but I can't be sure. You could try Everest Home Edition to see if that confirms it:


Here's a thread with someone who's asking the same question...it may be of some help:


If you can come up with the model number & board revision (you may have to open the case & see if you can locate that info printed somewhere on the board), this site will give you a list of the supported CPUs:


Asus A7N8X-X
1800+ @ 8.5 x 200MHz
768MB PC3200 2.5-3-3-7
Asus A9550GE/TD 128MB
WinME/WinXP Pro

Jam, you're a star! I've tried Everest Home Edition and it confirms your thoughts that i've got a Jetway 830CF/CH. I've posted the information it gave me below:

Motherboard Name Jetway 830CF/CH

Front Side Bus Properties
Bus Type DEC Alpha EV6
Bus Width 64-bit
Real Clock 100 MHz (DDR)
Effective Clock 200 MHz
Bandwidth 1600 MB/s

Motherboard Physical Info
CPU Sockets/Slots 1
Expansion Slots 3 PCI, 1 AGP, 1 CNR
RAM Slots 2 DIMM
Integrated Devices Audio, Video
Form Factor Micro ATX
Motherboard Size 210 mm x 240 mm
Motherboard Chipset SiS730S

I'll now try and find a CPU that the motherboard will support and then find somewhere I can buy it cheaply ;-)

This site will give you the supported CPUs...scroll down to the very bottom to find your board:


There have been several board revisions though (830CH , 830CH Rev1.0 , 830CH Rev2.0 , 830CH Rev3.0), you need to find out which one you have. At the top of the list in red it says:

Please Check your Model Number , PCB , BIOS and BOM Version First:

Click on that & a window will pop up showing you where to look on the board to get that info, then you can select the proper board from the list

Asus A7N8X-X
1800+ @ 8.5 x 200MHz
768MB PC3200 2.5-3-3-7
Asus A9550GE/TD 128MB

Mine is revision 2. The only other question I have is this...what is the difference between the 830CH and the 830CF? Because Everest Home Edition has mine down as 830CF/CH!

Actually, this whole processor thing really is a minefield. Even when I use websites like Kelkoo/Pricerunner/Amazon to try and find a suitable processor there are just too many that come up for me understand. Each processor is seemingly followed by about 60 different letters, all of which presumably mean something but none of which I understand. It's completely baffling! I guess i'll keep the old 1100 for now.

It looks like they both boards support the same CPUs, but you have to check the BOM version:




Asus A7N8X-X
1800+ @ 8.5 x 200MHz
768MB PC3200 2.5-3-3-7
Asus A9550GE/TD 128MB
