Hi, i have a Dell Optiplex G1, and i want to upgrade the CPU to a Celeron that i am looking at, and i don't want to buy another computer. Here are my Specificaions:

Dell Optiplex G1 (A09 BIOS Revision)
Pentium III 550MHz (100MHz FSB-Slot 1)
Intel 440BX Dell chipset motherboard (i think)
256MB SD RAM
Hard drive, burner, etc

I am thinking about putting a Socket 370 800MHz (100MHz FSB) Celeron in it using an adapter.

I am damn sure that it will work in it but i wanted to ask you if this will be an alright upgrade.

I can't find any faster Pentiums to put in it because i live in Australia and there arn't any over here anymore.

The question that i want to know is if i will notice any huge difference between my CPU's. I do play some minimal intense games, like Need for speed hot pursuit 2, soldier of fortune and motocross madness 2, but i have a new computer for all that. So it would be great if someone could tell me all the differences bewteen the two CPU's.

Thanks a lot for your time.

Daniel

There wouldn't be a huge difference but it will be a couple secounds faster for certain things.

First of all, you have to check if your motherboard would support the 10x multiplier in order to use the 800Mhz. It could be highly unlikely in my opinion.
Secondly, the gain would be minimum.

Why would you upgrade to a "Celeron"? Dude.. go with a Socket A Athlon 1700XP. It's dirt Cheap right now at about $43 bucks and is very overclockable.

Of course... I don't know what I'm talking about when it comes to overclocking but I know 1.7 gig is better than 800mhz.

Well the Celeron 800MHz actually has a 100MHz Front side bus and it has an 8x multiplier, not 10x. Maybe your thinking of the older Celerons that had the 66MHz FSB rating.

Dethlok, what do you mean go for a XP1700? Do you mean buy one and try and put it in my Dell i have now, or buy a complete new system with a XP1700? Coz i don't think an AMD is going to work in a Slot 1 Intel-based motherboard.

I was under the impression you were buying everything... including a mobo...

My bad..

And you're right... if they have a 100mhz fsb then they've definately gotten better (darn old text books.)

Anyway... I didn't read your whole post either. So as I stated before... I don't know what I'm talking about. I was serious when I said that.

Don't waste your money on a Celeron. To call it an upgrade from a PIII is a joke, in my opinion. I've been consistenly disappointed with the Celeron, even up to 1 gigahertz. Just because the chip happens to run at more cycles/second doesn't mean you will see a performance gain. If I were you, I'd get another 256 Megs of RAM. Avoid upgrading the processor in this box. I was very pleased with the PIII 500 I used for years. Good luck.

Even with the 800MHz Celeron your still in that old Intel propaganda zone. These older Celerons had 1/2 the L2 cache disabled so they didn't compete too heavily with the PIII's. They have only a 128k L2 cache. Doesn't your Pentium III have a 256k L2 cache? You may not even see a performance increase. L2 cache is the best memory you can stuff in a computer...why downgrade?

Won't one of the pricewatch.com sites ship you a decent PIII CPU in AU?

Hi Daniel

I recently saw an add in the Com Trader. For AU$110 it may be possible to boost your system to a Celeron 1.4GHz. Because your mobo has a BX chipset you can run a 100 FSB and because Celerons multipliers are locked, you can, 90% of the time, run a 1.4GHz processor. Email me if you need more deatils, BTW the guy who does it was from Melbourne.

Kind Regards

Hi Adam, i will e-mail you, but all i need is your e-mail address... When did you see this add? And if i were to upgrade my computer to a Celeron 1.4GHz i would need a Powerleap PL iP3 adapter to support the Tualitin core.

Daniel

i bought a 2400+xp and a motherboard combo for 99$ at frys. watch pricewatch, or even better, ebay. get a mobo/chip pIII combo pushing the 1ghz range for under 100$ U.S. i bet. i bet thats not too much more than crappy celerons and adapters and stuff. the L2cache on the 1.4 gig is still smaller than your pIII. depending on the application, i bet the difference is noticable, but nominal. a fast celeron is really like a souped up pII chip. i think the pII should retire.

Daniel,
Do keep this in mind before upgrading!!!
I also HAD the same set-up you have with the optiplex g1 and tried to upgrade it to a PIII 900mhz(instructed by some idiot with an angelfire.com website) and upon doing so fried the whole thing to hell and back.What happened you ask?One of the major things that was overlooked when upgrading was the POWER SUPPLY!I had the optiplex g1 low profile chasis in which the power supply will NOT handle anything above 550mhz!If you have the low profile chasis DO NOT attempt this upgrade!!!I'm not sure about the other mid-size or atx chasis but do check the POWER SUPPLY and make sure it will handle the upgrade or else you'll end up like me.

Hi, my Dell is the "low-profile" version with a 145W power supply in it. Why would the power supply not power anything over 550MHz? It's not as if a higher CPU is drawing that much more power... I mean this thing seems to be ok. I can power 2 Hard drives, A CD-ROM drive, a floppy and the computer.
