2x2pairsCorsair XMS3DHXCM3X1024-1600C7DHX

For sorry I bought (my system builder) 2 pairs of 2x1GB of memory, not 1 pair 2x2GB...

Now I have 2x2 pairs of Corsair XMS3DHXCM3X1024-1600C7DHX installed on MSI P45 Diamond and they don't work at 1333MHz. BIOS Pass, but when WIndows 7 (64bit Ult.) starting - PC hangs.
If memory set on 1:6 ratio=1067MHz- all is fine.
CPU is Intel Q9550, not overclocked

I read that Intel P45 chipset work only up to 1067MHz (for memory)? Is that right?

Is only way memory working at 1333MHz to be chnged with 1 pair of 2x2GB?

May I say:
1. that from MSI send me a new BIOS- changed, but not resolved,
2. Changing DDR3 Voltage to 1.8v - but not resolved

Is there any other ways to go?

When you run 4 sticks, you have to increase the northbirdge voltage to get the RAM working and stable. Increase your northbridge voltage, try 1 increment. If that doens; POST, or is not stable, increase another increment. Repeat as needed, until the RAM passes memtest86+.
Remember to set your RAM latencies and voltage to the specs on the stickers of the RAM.

Thanks for suggestions.

Some thinghs happend:
1. Memtes+86 booted from CD always pass test.
2. Trying many times with different votlages of MCH voltage:

DRAM [V]-----------Auto--1.8---Auto---Auto---1.6-----Auto--Auto-----Auto
MCH [V]-------------1,4---1.4---1.04---1.448--1.46---1.46--1.48 -----1.54
MCH GTL[V]-------Auto---Auto-Auto---Auto---Autp---Auto--0.742---Auto
Win warm start---Yes---No-----No----No------Yes----Yes----Yes-----Yes
Win cold start-----No----No-----No----No------No-----No-----No------No/Yes

***
Win warm start = if after BIOS settings go to starting OS
Win cold start = if successful warm start happened, normally shut down OS, power off cable unplug, wait for some time and try to start again
No/Yes = First unsuccessful cold start of OS. if unsuccessful Win cold start happend, reset buton pressed, go to BIOS, only view settings and Exit without save. But OS Starting normally !!? - What is this mean?

Any other suggestins? Thanks in advance!!
