K9n2 SLI Platinum DRAM timings will not stay

Question

First off, I would like to say that I am posting this for my friend and that we both love MSI products. His setup is
K9n2 SLI Platinum,
Phenom 9950 140 watt black edition,
2 gigs OCz sli ready 8500 1066 1x2 kit,
BFG 8800 GTS G92 core 512mb graphics card,
and Corsair 650 watt PSU.
I don't at this time of writing have any screens, I can only explain whats going on. When he goes into BIOS and sets the Dram timings to 5.5.5.15 moves the voltage to 2.0, sets the Dram to run at 1066 which I think is 1.2.66, it reads at the top of the BIOS screen 1066. He then saves and exits reboots into windows runs CPU-z and it shows the timings have changed to 5.6.6.16, when he shuts down and goes back to BIOS it has changed there as well to the 5.6.6.16. The BIOS is the most current 3.2 also all the drivers and updates are the most recent for hardware and windows Vista home premium 32 bit. I Am trying to be as specific as possible to help you guys help us. The ram is in Dual channel Unganged. Please note it reads in CPU-z even with the 5.6.6.16 timings 1066 rather 533 DDR2 however the ram supports 5.5.5.15 in timings so I don't think that this could be good for it. We have done Memtest on the ram all test did fine we also used the windows version no errors on both test, We have not used Prime95 yet.
Any help would be great and much appreciated at this point. His computer has crashed twice, once was the Blue screen of death and the other was just a lockup. I also should mention CPU, mobo temps I think are well within specs CPU idle 37c load 45c graphics card at idle 40c load 46c. Thank you for reading Shucky.

You are most welcome! Ever so kind!
No performace lost, instead higher efficiency like you noticed.
Think of it like this:
A pipe with a big diameter can transport a lot of fluid.
A pipe with high pressure, where things have a high speed, can transport a lot of fluid.
A pipe where the diameter is not the same in both ends. Well, you can't say how much fluid will come out the other end, at least not without a lot of calculating and testing. (Like you also noticed.  :D )
What is a pity is that program(mer)s have difficulties making use of all the cores. Phenom have four true cores. I think it will take about two years until all four can be put to full use, but if there ever is any real use in using all four cores is hard to say and a different question.
Sure AMD and Intel and Microsoft et al have found ways of distributing processor work, but they are far from optimized. And it isn't easy: Think of the project your work group got from your chief or teacher: How many should be involved? Or if you are 300 people in your dorm, or even just four of you in your family, should all help out with the washing up after supper?
No, is the best answer to that. So what has begun is developing processors, with a variety of cores. One may - as a silly example - make icons until or unless it can do better work somewhere else. - Not an easy thing making it do tasks like that, either! So that is why I did the washing up just now.
