Shaping the Diamond

[Crue73]

Got stability issues with my rig when using MSI CoreCenter D.O.T. (Dynamic OC Tech) after switching to a faster CPU. And I think I don´t have the BIOS right. Can anyone help me, please?

My spec.s:
PSU 750 W
GPU EVGA GTX 285 SC
Mobo: MSI P45 Diamond, hardware OC jumpers set to 266-333 MHz, Northbridge cooled passively (should I remove the water cooling casing?)
SoundBlaster X-Fi Xtreme audio
CPU: Zalman cooled Core 2 Duo E8600 3.33 GHz, temp. 38-40 degr. C
RAM: 2x2GB Corsair XMS3 DDR-3 Platinum Series (WinXP32 only exploiting 3 gigs)
USB peripherals: Flightsim. controllers

K, here´s the deal. Until now I had to limp with a cane still using my old CPU in my new rig, had the OC jumpers set cautiously to 200-266 MHz, and the MSI CoreCenter gently raised the bar from 2.13 to 2.6 GHz on my Core2Duo E6400. I now installed a Core 2 Duo E8600 3.33 GHz CPU, jumpers set to 266-333 (goes all the way up to 333-400 when removing the two jumpers).

The CoreCenter, previously showing dynamic changes in temp., FSB and Clock on the old CPU, now holds a pretty steady temp. around 38-40 Degr. C, FSB 334 and Clock 3342 constantly. When activating D.O.T (sharp mode) it doesn´t seem to adapt to the varying demands, values stay the same. And when starting up FSX my pc crashes.

Not using D.O.T. seems to be stable, FSX works (Yes, leave D.O.T off, got it ), but I was wondering if anyone could look through my BIOS if I post it. There´s probably a lot to correct. I´m too chicken to use BIOS Live Update, it practically warns you not to.
I´ll post the relevant BIOS settings in a reply.

Hope I got all relevant info posted.

PCI latency timer 96 (should I go 128?)

CPU feature
Execute BITsupport enabled
C1E Support disabled
Set limit CPUID MaxVal to 3 disabled

Chipset Feature
HPET enabled

Cell menu
Multistep OC booster disabled
DOT control enabled
CPU DOT step 1,2,3 1%, 3%, 5%
Intel C-state tech disabled
CPU FSB freq. 333
CPU Ratio 8
DRAM config. Auto
FSB/DRAM ratio Auto
Adjusted DRAM freq. 1333

ClockGen Tuner
CPU amplitude control 800 mV (range: 700-1000)
PCIE amplitude control 800 mV (range: 700-1000)
CPU CLK skew norm (range: norm, 100-1400PS)
MCH CLK skew norm (range: norm, 100-1400PS)

Adjusted PCI freq. default (range: def., 3, 42)

BIOS also tells me Current CPU freq. 2.66 GHz, easy math, but on desktop the CoreCenter seems to have control over frequencies (as long at D.O.T. is off).

Hope there´s a wiz out there who can help. Thanks!
