As the title says, I’ve been wondering if the quirky Intel VC820 motherboard supports Tualatins. I recently purchased one of these boards with the hopes of testing an alternative to a 440BX system I’ve got. I am in a weird way interested in RAMBUS setups and wouldn’t mind giving this a go, since i820 supports native 133MHz FSB, 4X AGP, and 1GB of RAM—theoretically putting it ahead of i815 in my book, due to that chipset’s unfortunate 512MB hard limitation on RAM.
As much as I love the 440BX chipset and my ASUS CUBX-E, I’ve had stability troubles at 133MHz with a Tualatin. I suspect it’s due to the overclocked AGP bus, but I disabled Side Band Addressing and found some success in stabilizing things there. Performance is great, but I have some occasional hangs on shutdown and after closing games and find this to be annoying.
I found an old thread on HardForum from 2004 where a user claimed to have gotten a Tualatin working on an Intel D820LP board (or perhaps a VC820; it is unclear as I’m not certain which board would have been in his Dell XPS but it would’ve absolutely been one or the other).
I have a pin-modded 1.26GHz Tualatin from the Korean eBay seller who pre-modifies them and it’s great. Their site claims support for the VC820 through a BIOS update. Would anyone happen to either have that update or know something about this? I attempted to contact the seller and didn’t hear anything back.
I can’t find anything definitive saying this board doesn’t work, but then again, I can’t find anything saying it does either.
Anyway, thank you in advance for your thoughts and help!
