Long time ago on a forum called FalconFly there was this guy named Gary Donovan, he asked :
Quote:Damn, if only there was a Clawhammer motherboard that worked with a V6K!
Then there was this other guy who named himself 'Thandor' or something
He said:
Quote:Hmm, time to develop a custom board with AGP2x ?
You could use the AGP2PCI Adapter in combination with an AMD Opteron 150 and some high-end board with 66MHz PCI slots ?
Only compatibility *might* be a problem.
And of course the money...
On which Gary awnsered:
Quote:Do they make a high end board with 66 mhz PCI slots? That would work with the proper AGP2PCI adapter assuming the adapter doesn't default to 33 mhz operation and nothing else on the PCI bus doesn't rob to much bandwidth.
Well, to begin : Looking at the AGP2PCI Adapter -->
The PCI connector is just the same as that one of an 3dfx Interactive, Inc. Voodoo 4 4500 PCI and 3dfx Interactive, Inc. Voodoo 5 5500 PCI
Those connector identify theirselves as :
Universal 3.3/5V 32-Bit PCIIf I'm not misunderstood every universal 3.3/5V 32Bit - PCI card should work in any PCI-X connector as long as it fits. So far I'm not aware of 'fake' ones like the whole AGP story with fake 'AGP4x' cards which behave as an AGP1x/2x card
I also asked some persons who have lots of knowledge about this : They say there aren't 'fake' PCI cards. So if the card fits, it should work.
But, I'm not willing to take risks. It would be nice if there's a way to test it (like testing AGP rate with a multimeter). Of course 'we' can try it out with an nVidia AGP2x card into the adapter. If the whole thing blows up it's not that bad since the 3dfx card survived
Well, are there any motherboard which support PCI-X ?
Yes, lot's of serverboards do. Many dual CPU board have PCI-X slots. A lot of Intel Server Boards for an Intel Pentium 4 do have PCI-X slots. But since the Pentium 4 isn't that good it's better to take a S939 board with one AMD Athlon 64 3500+/4000+ or something
Unfortunatly I haven't found S939 board with PCI-X yet. There are S940 boards but they are more expensive and you'll need at least one AMD Opteron 2x0 CPU which is more expensive than a normal S939 CPU.
Tyan does have some dual CPU boards. Most (if not all) boards will work with only one CPU
