NVIDIA 680i: The Best Core 2 Chipset?

nForce 680i Platform
At the top of the product line, and targeted at the "hard-core overclocker", is the nForce 680 SLI. It consists of two discrete chips, the 680i MCP and the 680i SPP. As we saw in the 590 chipset, one x16 PCIe slot is controlled by each chip. This provides dual x16 SLI slots for the 680i, similar to what was provided by the 590 chipset.
There is a significant new addition with 680i, however, in a third PCIe x16 slot between the x16 PCIe slots for SLI. This third slot is x8 PCIe instead of x16, but it can be used for a GPU on the 680i, with a new twist. This x8 slot is suitable for a physics processor combined with SLI.
If you prefer multiple monitors instead, you can even drive up to six monitors - two per card - with video cards in all 3 PCIe slots.
The nForce 680i provides a total of 46 PCIe lanes, with 18 lanes available on the 680i SPP and 28 lanes provided on the 680i MCP.
New features of the 680i are the addition of Extreme Overclocking capabilities and basic refinements of the features first introduced with the 590 SLI chipset. Features include:
Extreme Overclocking
True 2 x16 PCI Express SLI Support provided by two full-bandwidth, 16-lane PCI Express links.
Third PCIe Slot for Graphics Expansion
NVIDIA MediaShieldTM Storage includes RAID and SATA drive support.
High Definition Audio (HDA) can deliver 192 kHz/32-bit quality for eight channels.
USB 2.0 plug-and-play interface that provides easy-to-use connectivity for up to 10 USB devices.

Extreme Overclocking
- FSB speeds of 1333 MHz can be achieved with a CPU that supports this specification.
- DDR2 speeds of DDR2-1200 and beyond can be used to keep pace with overclocked system components. NVIDIA nForce 680i SLI MCPs support high-speed SLI-Ready memory
True 2 x16 PCI Express SLI Support provided by two full-bandwidth, 16-lane PCI Express links.
Third PCIe Slot for Graphics Expansion
NVIDIA MediaShieldTM Storage includes RAID and SATA drive support.
- Multiple Disk Setup Through a wizard-based interface, you can set up your drives for better data protection, faster disk access or maximum storage capacity. MediaShield automatically selects a RAID 0, 1, 0+1 or 5 configuration according to your needs. Advanced users can access RAID options directly.
- DiskAlert System In the event of a disk failure, MediaShield users see an image that highlights which disk has failed to make it easier to identify, replace, and recover.
- RAID Morphing MediaShield allows users to change their current RAID setup to another configuration in a one-step process called morphing. This eliminates the need to back up data and follow multiple steps in the process.
- Bootable Multidisk Array MediaShield storage fully supports the use of a multi-disk array for loading the operating system at power-up.
- Six SATA 3Gb/s Drives Combine up to six SATA drives into one volume for bigger, faster RAID. Drives can be configured as six RAID 0 (striped) drives for maximum throughput, or Single or Dual RAID 5 arrays. Hot plug and Native Command Queuing are supported.
High Definition Audio (HDA) can deliver 192 kHz/32-bit quality for eight channels.
USB 2.0 plug-and-play interface that provides easy-to-use connectivity for up to 10 USB devices.

I'm looking forward to this. Any idea on when you guys will have the bin numbers for the different rates of OC-ability? I'm planning on OCing my e6600 on this board this weekend; I'll post up my numbers if that'll help.Gary Key - Sunday, November 12, 2006 - link
We have not figured it out yet. Two CPUs from the same week and they both act differently during overclocking. We are still working with NVIDIA on this matter.Joepublic2 - Friday, November 10, 2006 - link
965 and 975 boards to my knowledge don't support a FSB/mem ratio smaller than 1:1. Does this chipset have the right multiplier to use DDR2-400 while retaining a 1066Mhz FSB?Gary Key - Friday, November 10, 2006 - link
The memory settings are sync or async capable on this chipset if you unlink the FSB and Memory in the BIOS. So the answer is yes to your question but believe me this chipset needs good DDR2-800 to get the most out of it. A 1T command rate can make a significant difference in several applications and games. We already found a 4FPS difference in Q4 at 1280x1024 with DDR2-800 at 1T instead of 2T as an example. We will have more on this in our actual board review.Joepublic2 - Monday, November 13, 2006 - link
I was asking mainly because a conroe board that could run a 4:3 FSB/mem multiplier could be an even better overclocker than the 965. One would only need RAM that could hit DDR 752 for a 500Mhz FSB for example.A great review as always!

Any idea if there are mATX boards using any of thse new chipsets on the way?Gary Key - Friday, November 10, 2006 - link
There is the possibility of the 650i Ultra being on a mATX board in late January. However, the suppliers might wait for the new NV Intel IGP chipset coming in Q1. We should have more information in December.

Should be CPU, the X6800 is not a GPU, lol.

Do all of the 680i SLi boards require active cooling on the northbridge? That's actually a deal-killer for me, as motherboard fans are about the worst ones out there anymore since they're small, fast-spinning (and due to those two characteristics they are noisy), usually short-lived, and I've yet to see one that is dynamically controlled by the temp of the northbridge.I'm guessng 650i boards don't require active cooling, but are any of the 680i boards using a non-reference design sporting completely silent cooling?
