Old Dimension 8200 CPU & Memory question

December 20, 2009 at 10:41:54
Specs: Microsoft Windows XP Home Edition, 1.994 GHz / 1023 MB
I have an old Dell Dimension 8200 that I am planning to give to my son. It has:

Original Dell i850 motherboard
P4 2.0 GHz Northwood - 400MHz FSB
1 GB PC800-45 RDRAM

I am wanting to upgrade the CPU to the 3.06 Northwood, but this is a 533MHz FSB chip and it currently has a 400MHz FSB chip. Dell's site, as well as people here, say the mobo is compatible with both 400MHz and 533MHz FSB processors. My question is, do I have to replace the RDRAM? The PC800-45 is 400MHz...any help would be appreciated. And Cobra, if you read this, your input would be GREATLY appreciated.

naturally, the ram speed goes after cpu speed.....bigger CPU Speed = Bigger RAM speed...

...you can try to lock PCI Frequency at 100 MHZ.....

Google is your friend

What do you hope to accomplish with any upgrades?

RDRAM is still pricey.

Upgrading graphics would probably yield a better price performance ratio.

The 8200's BIOS doesn't support HT, so if the 3.06 runs at all, you'll only see one graph in Task Manager. Might be a better idea to grab the 2.8/533 instead.

You don't have to upgrade the RAM. The first-gen i850 only supports PC-800, so faster RDRAM would be automatically underclocked to PC-800.

Don't waste your money on a CPU or RAM. If you feel you must upgrade something & you're still using the onboard video, consider adding a cheap AGP card. Otherwise, just give it to him as-is.

I'd look at bios options to see if you could change any setting. Dell's tend to be very locked down for things like cpu upgrades.

Not sure you can put more ram in. Maybe it has 4 slots of Rambus. You can maybe go faster if the board supports it.

A clean install of XP might make it snappy again. It is still a good system for most things.That rambus smokes. I am a big fan of it for things like photoshop.

I am kind of suprised too. I thought that the rambus line stopped at the 2 gig or so and they changed processors after that. I think I looked at this a long time ago and didn't think it would work.

Thanks for all the replies...after getting the info here, as well as looking elsewhere, I have discovered that in order to upgrade to a CPU with 533MHz FSB, you need to have (1) the motherboard with the 850E Chipset and (2) PC800-40 RDRAM. This PC has neither of these, so I am going to put the fastest 400MHz FSB CPU in and upgrade the AGP card...Both upgrades are cheap and maybe I'll buy him a good gaming system when (if) he graduates. Thanks for all the help.
