I am looking to upgrade current rdram mobo and still use old memory ( I have 1Gig), I'm looking at a Intel D850EMV2 can I upgrade to a celeron D cpu, Intel has no info that I could find seeing as how the 850 chipset is no longer supported.They do say however that the 845 is compatible . Any advice would be welcome, thanks
Damn, you're just an old skool aren't you? Wow, I haven't seen rdram for years now. I can see you want to upgrade, but why not go for a 21st century computers like a pci-e board. You can pick up one for around $400 decent. I think the 845 are the last known mobo to support them old skool memory and Intel had completely abandoned it on 2004.
oh well :? thought I would check and see before I buy one (as suggested buy a retailer, and if it didn't work I could just return it. Ya....Right!),I guess this means I have to scour E-Bay and smaller comp shops in order to find a cpu.I currently have a 1.5 P4 w/d850mvl mobo,Its going to take a little bit of luck to find a 2.0-2.4 cpu w/533fsb and 256L2 for the 850E
It seems my problem is going to be L2 cache size. Which is the same problem I have had w/my old MVL mobo the only difference being the FSB speed 400 versus 533. At least there's more 533's out there than 400's
The 850 chipset will handle any socket 478 Willamette, Northwood "A" (400 FSB) or Northwood "B" (533 FSB). It takes RDRAM up to 800MHz.
You can get some Celerons that are Prescott cores and have a Socket 478 package, but I forget the number. Most are socket 775, so make *sure* you get a 478 model. They are a 533 FSB and *should* work but dollars to donuts the BIOS will act all flakey on you as it won't recognize the proc correctly.
