nForce 590 SLI reborn

An image of an upcoming NVIDIA nForce 680i SLI based motherboard has been leaked on the AnandTech forums. DailyTech previously reported NVIDIA was replacing its nForce 590 SLI Intel Edition with the nForce 680i SLI.

The motherboard is manufactured by eVGA and appears to be an enthusiast offering. It packs three PCI Express x16 slots, two PCI Express x1 and two PCI slots. While two of the PCI Express x16 slots are full-speed with sixteen lanes, it’s unknown what the lane configuration on the third slot will be. With three PCI Express x16 slots it appears NVIDIA may be taking on ATI’s triple-play physics processing architecture.

Other notable features of the nForce 680i SLI motherboard include 1394a, onboard high definition audio, dual Gigabit Ethernet and a heat pipe cooler for the MCP and SPP. It is unknown which high definition audio codec is used on the upcoming motherboard. Nevertheless, it will most likely be an ever-so-popular Realtek high definition audio codec.  

Performance and overclocking information on the upcoming nForce 680i SLI motherboard is unknown at the moment, though the thread originator promises more details next week.  eVGA is expected to ship the 680i motherboards in bundles with the upcoming GeForce 8800 series video cards at launch.

Update 10/13/2006: This image was sent out by NVIDIA PR to various sites. The motherboard is manufactured by Foxconn as eVGA does not have production capabilities like ASUS, XFX and Gigabyte.

I doubt if it is leakage from USB lanes. More like analog-crosstalk from the ground-current noise from the CPU -- up to 130 amps of peak-spike current rushing back and forth between the CPU itself and the CPU voltage-regulator capacitors. A common malady on integrated-audio motherboards of the ATX variety, where the audio signal circuit-board traces cannot avoid running close to the CPU or its power-planes. BTW, I have a A8N32-SLI also and use the optical output to an external amplifier/decoder. No noise on the optical output! Lots of noise on the analog outputs. Not an A8N32-SLI-exclusive problem. I have encountered significant analog-audio noise on every integrated-audio motherboard that I have encountered. Maybe my tolerance threshold for analog audio noise is much lower than the average PC user?

I haven't heard jack on any of my onboard audio motherboards. I DO remember way back when I wouldn't touch onboard audio with a ten foot pole for the reasons you mentioned but I haven't had a problem in at least 4 years. The newer stuff is MUCH better. My A8N-SLI board is the best I've ever owned. And I'm STILL on the original bios (1002). Stable as a rock.

It might be that your equipment is more sensitive, I too find practically all onboard audio in the past 6 years or so, terribly noisey but if you hook low-grade consumer amp up to it (as in most, even so-called-good, computer speaker sets) much of the noise is gone, but not all. Then again, some people can't hear artifacts in 160kbps MP3 either, so,
