Intel D975XBX: Intel brings their Bad-Axe to Market

FSB Overclocking Results
We tried two other boards, but we did not have success in increasing the CPU multiplier past 20 or utilizing a combination of the CPU multiplier and the FSB frequency override setting past the reported numbers. Even though this particular CPU has reached 4.4GHz, we could not pass the 4.0GHz mark and maintain stability or complete our test suite. We will be receiving a retail board shortly and will re-examine the overclocking ability of the board with our 840EE, 950D, and 955EE processors.
Memory Stress Testing
Memory stress tests look at the ability of the Intel D975XBX to operate at the officially supported memory frequencies of 667MHz DDR2, at the best performing memory timings that the Corsair CM2X512A-5400UL revision 1.3 will support.
The Intel D975XBX was very stable with 2 DDR2 modules in Dual-Channel at the settings of 3-2-2-8 at 2.1V. We will now install all four available memory slots that are usually more strenuous on the memory subsystem than testing 2 DDR2 modules on a motherboard.
The Intel D975XBX was completely stable with 4 DDR2 modules in Dual-Channel at the settings of 4-2-3-8 and needed the voltage increased to 2.2V. We tried several combinations of memory settings at the CAS Latency of 3, but the board was not stable enough to complete our test suite. This is the first i975x board that we have tested that did not allow a CAS Latency of 3 in our testing with 4 DDR2 modules.

Im a self build Virgin - but I'm going in at the deep end. Intel's site makes their Dual Core stuff sound awsome!(a) Is it?(b)Should I look to spend my cash elsewhere when considering a motherboard/processor?Gary Key - Saturday, July 15, 2006 - link
This board is fine for stock performance and if you get rev-0304 it works very well with Core 2 Duo.FOXY25 - Sunday, February 4, 2007 - link
hi that are my system setting. My system sometimes make complete restart and i dont know why. I have change entire board with another and nothing. Do y think that could be in memory i have 2x DDR2 1024 MB at 800 Mhz Kingmax. thanks for answer.Foxy====== Board ======

Does this board support dolby digital live in the sigmatel audio chipset? I'm looking to replace my old SoundStorm setup.Also, does Intel High Definition = Dolby Digital Live support?

Unlike most users of this motherboard that want to use the dual x8 PCIe slots for graphics, I want to use them for benchmarking a pair of x4 data acquisition boards we are developing. I want to test max rates to and from memory, as well as peer-to-peer transfers between the two boards (assuming the MCH allows this).So my question is: Do you think I can I put a x16 or x8 PCIe graphics card in the third x4 PCIe slot hanging off the south bridge? I don't care about graphics performance too much, I just want a dual monitor card that will work in that slot and leave the main two slots free.
And ideas on this would be helpful. Thanks!

I will try it this weekend and report back.neilfeier - Friday, March 3, 2006 - link
Thanks Gary, I anxiously await the results of your experiment.Neil

Hi Neil,I had video working in this slot. I updated to the new bios release today and will test the performance in a couple of days.
Thanks,
Gary

Neil,Performance is average but it works.

error! That's not how pcie works! pcie is always full duplex, and never single-ended!
