My sys specs are: msi p45-c51 mb, intel q8300, patriot ddr3 1333, msi 4770 cyclone, winxpx86, and a chieftec 450W ps. After restarting (and only after restarting not after shutting down) my system just freezes, the blue LEDs on the MB are lighting (despite of they are turned off from bios) and only turning off the system helps this problem.

It is interesting, that by pressing the reset button or the power button the system reacts the same (turning off), but a short after it is turning on again(by itself). When I power on the system by pressing the power button, the system is reacting only a short after (3 sec), and then starting. Is it normal?
But what is more interesting is that the system clock is putting away, so it is showing the wrong time. And the VGA driver is also gets wrong by these time. The clear cmos jumper is set to keep data. Another interesting thing is that the dram voltage is 1.8V by default and the MCH voltage is 1.46V by default (according to the dual core center information). And the DualCoreCenter is showing that the 3.3V is 0.1V, 5V is 0.07V and the 12V is 0.12 V. What the hell this problem could be?? I have been testing the system with one module for days.
One of the modules is working fine @1333 but with the other the system is rebooted during a video. The picture and the sound freezed and short after the system rebooted spontaneously. That's all what happened during the testing period. With 2 modules @1333 the system is still unstable.
Another strange thing is happening all the time: when the windowsxp loads the screen reloads just like after a successful video driver installation. I think this should happen only one time after the driver installations, am I right? Thanks for your reply!! System is stable @1066 with both rams installed.
I've installed both drams @1333 and set the timings to 'auto' and after that the timings are still 9-9-9-24. I've just set the settings to auto, so I can't tell what will happen, but at these settings the system was unstable.
But I could use both drams @1333 with manual timing settings, and everything was fine. I've just noticed that the memory voltage at DCC is 1.8V It's written with purple color, so I guess it's not ok.
UPDATE: system is unstable again with 2dram modules,@1333 with manual timings.
. low speed devices: working unstable because sometimes the USB subsystem freezes when a low speed device gets removed from an USB 3.0 port. Try to avoid them. full speed devices: working stable.
high speed devices: not working. super speed devices: working stable.
Note: The bug which caused the system to hang when any device was plugged into an USB 3.0 port is fixed since version DSDT-MSI-B75MA-P45-V1.2b.aml. For BIOS version 1.4: Tested with Mountain Lion 10.8.2. Onboard Graphics: working. Audio: working with patched AppleHDA for ALC888b/887 v100302 from Multibeast 5.2 (layout-id 2). LAN: working with Lnx2mac driver. Sleep: working.
USB 3.0 ports. I managed to get the USB 3.0 ports fully working with USB 2.0 devices by creating a rather complex DSDT patch for BIOS version 1.4 which was inspired by an extracted DSDT from a mid 2012 Macbook Pro.
As the patch is far from being trivial it must be considered experimental and needs further testing. I wasn't able to test if sleep is working because my machine is running the server version of Mountain Lion 10.8.2 which doesn't sleep anyway. Although my system is running stable with the DSDT use it at your own risk and be prepared to recover your installation in case something goes wrong. The experimental DSDT is obsolete because I integrated the USB 3.0 patch into the regular Version 1.4 DSDT (see above). I did what you told me to do I upgraded the bios with the modified version and set all the settings inside the bios as you stated with the pictures i downloaded from you, How can it be I cant get into the installer still? It just keeps spinning and spinning beach ball.
All i have is the i7 2600 not the K series a measly xfx 6670 and 8 gigs of ram a wireless pci-x card and a ssd 128 gb drive dvd rom thats it I also tried just to boot from the onboard graphics same results. Please man I need ya.
