Intel Celeron question...

[Mini-Me]

Hi all.

I am an AMD user/builder, so know nothing about Intel CPU's.

I have a Dell GX100 machine, fitted with a 566 Celeron CPU.
The manuals for this box, make no mention of what is the fastest CPU you can put in the box.

I am wanting to put an 800MHz celeron in it.

I contacted Dell, but they want a serial number, which I don't have, as the box was bought 2nd hand.

The manual mentions that the system speed can be either 66 or 100MHz.(external bus speed)

Any thoughts?

Just one thought for now. Download and run Everest Home Edition (http://www.lavalys.com/products/download.php?pid=1&lang=en) and give us the details under the CPU and Chipset sections. Also, tell us whether this is a Slot 1 system or a Socket 370 system. After that, I can help you.

[Mini-Me]

I can tell you right away, that it is socket-370. I will download the program, and post details tomorrow. Thanks for the link! :)

O.K.
Here is the result of the test you asked for.

Hope that helps.

So, what are my chances of plonking an 800MHz Celeron CPU in this machine?
Thanks!
:cool:

Hmmm... 800MHz would be iffy. 766MHz would probably be fine. Once the Celeron's hit 800MHz, they went to a 100MHz FSB, which is technically supported by the chipset but you'll have to check for a BIOS update from Dell to support the new CPU ID strings. For PIII support, you could probably go higher, up to a 1GHz Coppermine PIII (100 FSB) for the chipset, but again you'll have to check Dell for BIOS updates in case their mobo doesn't handle that already.

The fact that the mobo is a Dell doesn't entirely cut it out for upgrading, but it does limit potential in terms of OC'ing options. I'll stop there for now, but I can tell you your options if you want...

[Mini-Me]

Hey, thanks for your help!
:)

I am looking at the Dell page now, and you CAN get an upgraded BIOS for this machine. I will download it, and use it, if the 800MHz proves a problem.

Dell say, that you can use Celeron's with 100MHz FSB in this machine.

By all means, please suggest options!
:cool:

Hi all.
:)

Just to keep everyone here in the loop, I have now installed the latest BIOS for this machine. The old BIOS was version A04, and I updated to version A10.

Old BIOS date was sometime in 2000, and new BIOS is 30th August 2001.

It is always a very scary moment, when the time comes to re-flash the BIOS.
:p

...you PREY that there is not a power-cut during the 10 second re-flash process!

:D

[saphalline]

Ok, you should be able to upgrade to a Coppermine-128 Celeron at 1.1GHz. Do not try a Tualatin Celeron! The C-128 core revisions can be distinguished by their 128KB of L2 cache (while the Tualatins have 256KB) so that's all you have to look for when shopping. Those older Socket 370 Celerons are dirt cheap these days and still being sold a lot, so you should have no problems finding one for around $40-50. Considering the cheap cost of a much faster Celeron, OC'ing might be overkill. :D

However, if you wish to know... Providing that Dell mobo will actually let you specify the FSB speed manually, you could open up some OC'ing potential for that 566 you have now. For such a slow Coppermine-128, you could probably jack the FSB from 66 to 100 without much of a problem as long as your cooling is good. That would take you from 566MHz to 850MHz! :eek: Like I said, it's probably overkill and of course there's a risk involved with all OC'ing (not to mention the Dell BIOS may be working against you) but there's always hope... ;)

[Mini-Me]

Hey, Saphalline, thanks very much for the help - you have been a gold-mine of useful info!
:)

As I said at the start, I know my AMD inside-out, but Intel, I stopped working with, beyond the P233 socket-7 flavour!
:p

Also, that Everest system tool is brilliant...
:)
Thanks for putting me on to that one!

I bought the 800MHz Celeron for NZ$60(30 bucks US) a month or so ago - the price was right - even came with heatsink and fan(new)...

I don't like overclocking.
Two reasons mainly:

1) You are outside of the manufacturer's ratings, so void your warranty
2) Generally speaking, OC'ing causes the CPU to generate more heat internally, and can(in some cases) be so great as to be generated faster then the heatsink can suck it away from the die, resulting in catastrophic CPU core-failure - the CPU dies...
:(

Appologies to those reading this who OC, I just don't like it myself.
Only my 2c...

Wow, that was a good price for that Celeron! Too bad SDRAM and S370 mobo's are so expensive, otherwise older Celeron systems would be a steal! But the new Celeron D's and Sempron's aren't much more expensive, and their supporting mobo's are cheap enough. And of course DDR is half the price of SDRAM! Turns the tide a bit on those older Celeron's. :( But they make good & cheap upgrades! :D

[Mini-Me]

Yeah, you can buy an entry-level Sempron CPU(2200+) here for $97 or so(about 50 bucks US) - this is NEW, genuine AMD with heatsink and fan...
