Need to find out FSB speed

[Eyecan'tcode]

I have a Dell OptiPlex GX270 with a dead mobo (this model had a manufacture capacitor issue) and I need to know the FSB speed of my processor so that I may order the correct one. The motherboards I'm looking at are compatible with 400/533mhz; 800mhz is not compatible. Did this model come with a 800mhz option?

That motherboard supports 800, 533 and 400 MHz FSB. I'm pretty sure a 3.4 GHz P4 (listed in your specs) will have an 800 MHz FSB.

Be careful buying motherboards for Dell cases. I don't know that particular model but some have unusual mounting holes and dimensions and different power connectors.

Thanks for your reply. I'm trying to find out how to determine which FSB option that I have. The replacement mobo's that I'm looking at are not compatible with 800mhz processors.

You could use a tool such as SIW and get more information than you ever wanted to know.

Or CPU-Z: http://www.cpuid.com/cpuz.php

But with a dead motherboard he won't be able to run any software.

Look for the s-spec number on top of the actual processor. It is a 5-digit alphanumeric starting with S. Then go to Intel's website and find the processor model using that number.

Why exactly is it that you wish to spend money on out-of-date, obsolete equipment?

If you can wait a bit, I'll likely be throwing a 400 MHZ board into the garbage, probably some CPU chips, as well,

I don't think they made a 3.4 at 400, you probably have an 800 MHZ chip. If not, get a new chip to go with the new board.

Its a 4th pc and mother boards for this model are cheap.

The chip I have is 2.2ghz

you would be better off going to a place that has computer auctions (not a website)
you should be able to pick up a complete PC (without monitor), more up to date model for less than the cost of a replacement motherboard.

I do have a GX270 at work which run @2.6 and it is running at FSB 800mHz.
You could look at the service tag number on the case and go to Dell's part website and find out exactly what you need.

Oh, one more thing, unless it a Dell replacement board, the MoBo you buy may not fit in the Dell case. If you notice the position of the CPU on the Dell board (the heat sink and the fan which blowing air toward the CPU under the big green plastic cover), you may have an BTX case and ATX mother board will not fit in the case without major modification to the case.

The max 400Mhz FSB chip on a Northwood was 2.8Ghz (the 3.0Ghz was never mass produced). I've got this processor on a step-up 423>478 socket adapter. The system originally came with a 1.8Ghz Willamette CPU.

It was more cost-effective to upgrade the system, rather than replace everything.

Thanx guys. Dell informed me the chip is 533mhz FSB
