Overclocking - QX6700
Needless to say, quad core overclocking on this board is slightly better than most of the 680i platforms but is a disappointment when compared to the recent EVGA 680i LT SLI. Our board reached a final 360FSB at stock or lower multipliers. We were able to POST and enter XP at 372FSB but could not complete our benchmark testing. In comparison, the 680i LT SLI was able to reach 10x362 and 8x432 FSB speeds.
Just like the 680i LT SLI board we had to set our processor voltage to 1.4750 in order to maintain system stability at 360 FSB. Our processor normally will run in the 3600MHz range at 1.4125V. The reason for this is that Vdroop was just acceptable on this board with a quad core processor. We would see drops as high as .05V under load testing with the average drop being around .02V during game testing. Since our quad core results with the ASUS and MSI 650i/430 boards are very similar, we believe the 650i SPP is the limiting factor in overclocking this processor.
Test Setup
A 2GB memory configuration is standard in our XP test beds as most enthusiasts are currently purchasing this amount of memory. Our choice of mid-range OCZ Flex XLC PC-6400 memory represents an excellent balance of price and performance that offered a very wide range of memory settings during our stock and overclocked test runs. We also utilized our Corsair XMS2 Dominator (Twin2x2048-9136C5D) memory on this board to verify DDR2-1066 to DDR2-1200 compatibility with another memory type.
We are currently completing testing several other memory modules ranging from Transcend, TwinMOS, and WINTEC DDR2-800 down to A-DATA DDR2-533 for compatibility and performance benchmarks in our 680i roundup article. Our memory timings are set based upon determining the best memory bandwidth via MemTest 86 and test application results for each board. We only optimize the four main memory settings with sub-timings remaining at Auto settings.
We are utilizing an MSI 8800GTX video card to ensure our 1280x1024 resolutions are not completely GPU bound for our motherboard test results. We did find in testing that applying a 4xAA/8xAF setting in most of today's latest games at our standard resolution did not really change performance. Our video tests are run at 1280x1024 resolutions for this article at High Quality settings. We also tested at 1600x1200 and 1920x1200 4xAA/8xAF for our NVIDIA SLI results that will be presented in our MSI P6N Diamond article.
All of our tests are run in an enclosed case with a dual optical/hard drive setup to reflect a moderately loaded system platform. Windows XP SP2 is fully updated and we load a clean drive image for each system to ensure driver conflicts are kept to a minimum. We were able to run our memory test modules at 3-4-3-9 1T for our benchmark results.

this mish-mash of different chipsets probably works fine under windows, because asus will provided a tailored nVidia driver to ensure it works.but they have always been rubbish at providing a linux variant of the proprietary systems design.
can i use the standard release nVidia linux chipset drivers to use this board under linux?
if the answer is 'no' then this board is garbage.

This board uses the standard NVIDIA 680i driver set in XP and Vista. I had no issues loading SUSE 10.2 on the board but did not test it extensively with RAID or other options. The ADI audio worked but not as well as the Realtek offerings on other boards.yacoub - Monday, April 2, 2007 - link
but only for you and the other handful of folks in that situation...yyrkoon - Monday, April 2, 2007 - link
Yes, and no. Because users are fed up with MS/WIndows/Vista, a lot of users are making the plunge into Linux.Anyhow, it is the softwares responcability to comply with the hardware, not vice versa(to a point that is, obviously the hardware does need to comply with each specification, IE SATA, IDE, x86, etc.), if Linux is to be taken seriously, the Linux dev teams NEED to write a module for every possible chipset out there . . . if not, then well, you will have what you currently have right now, an OS, that does not support near as many hardware configurations, as Windows does.
Linux is a fun OS, and great for certain situations, but when you have problems like those caused by udev, and whatever else, you can not help but feel like it is not complete. Granted, the Linux dev teams for each distro, is usually much smaller than the teams that write code for Windows. End results however, tend to make this user feel as though Linux is a toy OS, with lots of work still needed. Ubuntu, is good for some situations, and a cutting edge Distro such as SabayonLinux, is also not without its quirks(but 'feels' very simular to Windows Vista.).
The end result is: what do *you* expect from a free OS ? Personaly, I like each, for different reasons, but still consider Windows to be the only real serious OS, mainly because of support for many, if not nearly all forms of hardware. Look and feel also are a consideration, but Linux has been closing the gap here, for a long time now.
Anyhow, that 'handful of users' is growing day by day, and is not really a 'handful' any more.

I could really use to see one. I don't see the differances between this board and a regualar 680i chipset, aside from the northbridges being different (which you would think would impact total PCI-e lanes but... apparently not..).so can you put together a map?
