After the recent discovery of the cause for many headaches [Intel core 2 quad Q9550(45nm) + nForce 680i LT] = no mobo support for chip. Presuming the board is the problem causing random lock-ups due to lack of support and not being made for the chip and whatnot(Apparently they shouldn't even boot together...)
...I have decided to get a new motherboard.
My question now though, what to get? It looks like production on socket 775 boards has stopped entirely, and only leftovers are on the market.
SLI/Crossfire isn't a major factor for me, especially with the dual gpu cards on the market, but is still nice to know I can upgrade.
That's what I thought when I got the processor for it. But the 680i(& LT) do not support the 45nm Quads.
NVIDIA nForce 680i Motherboards Do Not Support Quad Core Yorkfield
You may've heard the rumors too, but I waited on purpose before posting this one. It's now confirmed by NVIDIA what's up with 680i motherboards supporting the new quad core Yorkfield processors:
The (680i) MCP fully supports both dual core Wolfdale and quad core Yorkfield, but at the board level, a motherboard circuit change is required for quad core YF.
All NVIDIA nForce 680i motherboard owners should have in mind that their current mainboard won't support Yorkfield, probably not even if a new BIOS is released. Hardware modification is needed, which most likely means you have to buy a new motherboard.
EVGA 680i users,
The EVGA 680i SLI motherboard will support 45nm Wolfsdale (dual core) CPU's with an upcoming BIOS update. 45nm Yorkfield (quad core) CPU's will be supported on upcoming nForce 700-series SLI motherboards.
I've got a yorkfield...
This cpu is great, just need a motherboard that fully supports it.
