my current spec is:

Intel® Desktop Board DX58SO
CORSAIR XMS3 4096M DDR3 Kit 1333MHz, 2x240 DIMM, DHX (TW3X4G1333C9DHX)
WESTERN DIGITAL CAVIAR GP 500GB SATA2 7200RPM 16MB (WD5000AACS)
INTEL CORE I7-920 2.66G 8M LGA1366 BOX (BX80601920)
MSI GF GTX 260 PCIE 896M GDDR3 2X DVI OC (N260GTX-T2D896-OC)

At the moment my i can only use 2Gb of memery, when i put in the other memeory my pc wont boot. Tried last night again after running with 2GB for the last 2-3 months.

On intel site it says:
What is the maximum frequency for DDR3 memory when used with Intel® Core™ i7-900 processor series?

These processors support DDR3 memory with a maximum frequency of 1066 MHz. If faster DDR3 memory is used (such as 1333 MHz or 1600 MHz), it will be down-clocked to operate at 1066 MHz.

I can not find any place on intel.com if my RAM is supported or not?

My motherboard support something like 3 chanel something something, so I think i want to try 3 x 2 GB of RAM and install win 7 64, what do you think?
By the looks of your post, you're only using a dual channel DDR 3 kit, when the i7 uses triple channel kits. Have you only got 2 RAM moddules?
