Test Setup
A 2GB memory configuration is standard in our XP test beds as most enthusiasts are currently purchasing this amount of memory - and we personally wouldn't think of running Vista with less than 2GB. 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 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, and we will provide more details on performance/compatibility with these memories in a future 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 8800 GTX 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 does not cause the performance of the system at our standard resolution to really change (i.e. we're CPU limited with the 8800 GTX). Our video tests are run at 1280x1024 resolution 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 an upcoming 680/650i roundup.
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. The MSI P6N SLI Platinum defaults to a 268FSB so we have to change our settings to manual and reduce the FSB to 266, and that also resulted in our DDR2 memory speed dropping to 799. As you will soon see, this did not have an adverse effect in our test results.

Great article. Thank you Gary.cosmotic - Wednesday, March 14, 2007 - link
How can you say that MSI software is decent? It's totally hideous. I think Anandtech owes it to the community to encourage motherboard manufactures to start writing native-feeling Windows applications instead of these crap piles all the manufactueres are shipping now. This includes AMD/ATI, nVidia, Realtek, and many others for their drivers as well.Gorgonzola - Thursday, June 21, 2007 - link
I could not agree more!anandtech02148 - Wednesday, March 14, 2007 - link
Here I go againcomplaining about the psu and power consumption, but 300watts load,200watts idle,
not to mention fancy subwoofer, a few electronics here there,
good gaming is in the summer time, and i'll be cranking up the AC too which is another 250wtts.
i wish newegg.com would sell me a n.korean light water nuclear reactor so i can run all my greatest hardwares.

Hey Gary,Since it looks like this mb outperforms pretty much every other board in the review in most tests (at stock speeds, where head-to-head comparisons usually take place) - including the much touted 'Extreme' board(s), do you plan to include it for comparisons in future reviews?

The 650i uses 21% more power on idle compared to the ICFX3200. What is nV doing with all that power? This seems absurd.Gary Key - Tuesday, March 13, 2007 - link
It is being channeled into the on-board Flux Capacitor. ;-) I can tell you that we have hounded NVIDIA to no end about this issue with their chipsets. It should be addressed when they finally go to a single chip solution later this year (we are still hoping this occurs).

If I were to venture a guess, NVIDIA probably isn't doing any proper power savings work for the chipset. Just like with CPUs and GPUs, there's a lot of stuff on the chipset that is often not in use and can be put into a sleep/deep sleep mode. The 650i and 680i use 100-107W more power at full load than at idle. The 975X uses 141W more at load, P965 139W more, and RD600 105W more.IIRC, AMD is using a newer process technology for RD600, so that would help explain their lower overall power. Intel seems to benefit from power savings in idle mode, but at full load they are pretty close to NVIDIA. The extra "stuff" in 680i relative to 650i could easily account for the added ~10W that it requires. Seems to me like all companies involved could do more with chipset power savings. AMD is just ahead on the process tech (again, I think); Intel uses an older process but decent power saving circuitry; NVIDIA doesn't do anything to conserve chipset power.
When you consider that at idle the PC is doing nothing important, AMD and Intel should drop CPU clocks further (600 MHz ought to be enough), and they could drop FSB/bus speeds and chipset voltages as well. Why run 1066FSB when you're doing essentially nothing? Why run 1000MHz HyperTransport to transfer... nothing? I believe AMD does drop HT speeds at idle on their mobles chips, so why not on desktop offerings?
Just my two cents.

Patiently awaiting the Gigabyte version of this board, as I was most interested in upgrading to the 965DS3 board rev 3.3, but the 650 look like it is worth the wait. Also, since the C2D price drop isn't until late April, I have time to wait and make a decision once that board is available. Good read as usual guys !ghitz - Tuesday, March 20, 2007 - link
Exactly what I was thinking !!
