I want to upgrade the cpu. i found this neato one i want really bad.

http://www.pricegrabber.com/search_getprod.php/masterid=513473/search=processors

its a 1.2 GHz, 256KB, 100MHz, Socket 370 intel celeron processor.

based on my specs, i would like to think this cpu is perfect and i should go ahead and buy it cause the sockets match, its a celeron, and its faster! :p

however, while reading the latest issue of maximum pc, a reader was asking about his hp computer and how he too wanted to upgrade to another cpu with the same socket. but maximum pc says it wouldn't work cause of some 500mghz fsb limit in the mobo or whatever.

do i have a similar limitation?

also. is it really a limitation or more like its pointless cause of some bottleneck thing going on?

any opinions/tips/help would be appreciated. thanks in advance.

Hi Tact,

Download and install Everest Free from: http://www.lavalys.com

It will inventory all of your hardware including SMART, temperatures and fan rpms.

It will tell you the front side bus (fsb) limitations of your mobo, and you can find out processor capabilities in this area on the Internet. For example, I run an i925 PCI XE mobo with an Intel P4 540J CPU which has an fsb of only 800fsb while the mobo has a 1600fsb capability. Thus my mobo runs at the 800fsb speed and no faster. I have to upgrade my CPU to get it to match the 1600 fsb speed of my mobo - a planned future upgrade when I can afford it.

ok. so now i'm assuming that i have to find a cpu that not only matches sockets, but fsb?

also. is it possible that this article (the link posted above) is probably outdated and back then the fastest celeron was a 533? i still really wanna try out this 1.2 ghz >.<

Tact,

Find a CPU that matches sockets to be compatible with your mobo, so you don't have to get a new mobo.

Find a CPU that matches your fsb speed if you want to keep the CPU fed with data at its maximum potential rate and not be limited by your mobo. If you go better, then you are definitely limited by your mobo fsb. If you go less, you are then limited by your CPU fsb speed. For example, my CPU is rated at 3.2GHz, or 200MHz fsb speed multiplied by CPU multiplier (16), but its max is only 800fsb, whereas my mobo is 1600fsb, i.e. it has excess capacity and only runs my CPU at the CPU fsb=800=half its (the mobo) rated throughput.

The article you refer to may well be out-of-date by now.

Front Side Bus Speed

The CPU bus speed also known as "front-side bus speed" (or FSB) and is the speed at which the CPU communicates with RAM memory and the motherboard chipset. Athlon XPs have a 266MHz, 333MHz, or 400MHz FSB, Pentium 4s have a 400MHz, 533MHz, or 800MHz FSB, and socket 478 Celerons have a 400MHz FSB.

The highest front side bus speed available to the public to-date is 800MHz—its high bandwidth between the processor and the rest of the system improves throughput and performance. However, one should not assume that the CPU with the fastest front-side bus is the fastest performer. There are many factors that influence CPU speed, the most important are its design and efficiency of its floating point unit, the internal clock speed of the CPU (the GHz speed it's rated for), and the speed of its L2 cache.

Check out: http://www.gen-x-pc.com/fsb_info.htm
for more info on fsb.

Forget it. The mobo only supports 66Mhz front side buss. The celeron you are looking at is 100. If I remember correctly, the 1.2 also is a different voltage than what your mobo can supply.

cool. well at least i know that voltage counts as well. and now that i know my fsb (thanks to sacstc) i can now do more specific searches and see what the fastest cpu ever made with those req's is.

thanks a lot you guys. really appreciate it.

...does a quick search online...

bingo. aw sweet. this rules too! practically double what i hav now!

..i'm not sure where you're searching, or for what, but..

..first, google is your friend, learn it, use it, as an example, see below...
..second, pII and pIII are two entirely different models, with drastically differing requirements..

http://www.google.com/search?biw=872&hl=en&q=pentium+2+speeds

good info here..
http://www.geek.com/procspec/intel/pentium2celeron.htm

..and here..
http://www.infohq.com/Computer/intel-pentium-iii.shtml

..finally, this site lists actual models and their speeds,
http://users.erols.com/chare/remark.htm
..[as you can see, you could go to a 450, but just wasting your money for the gain acquired].. :eek: :(

1. i was using google before you ever knew what it was.

2. imo, as long as the sockets match, i still think i can use a PIII. i merely need to give in to other limitations such as voltage some motherboard limitations. which is why i came to this one. and i think it rulz.

ps. i used google to find the link above.
