Cant Load Win 7 64 after rebuild NF980-G65

Question

Hi
I have just bought an NF980-G65 mob., with an AMD Phenom II X4 955 (Deneb 4c)
3.2 GHz, DDR3-1333, 2 MB L2, 6 MB. I also bought the G-skill 1600 ram, I was a bit put of when it came as it was for an Intel pro,
I have it set up with two Nvidia 7800gt G.cards. in SLI
I installed a new hard drive W.Dig. 650gb black. when I tried loading win7 64 i kept getting a blue screen with various faults on it.
It would work as far as the grey line "loading windows" and even the logo sometimes but would then crash.
The amazing thing is that i put my old hardrive back in and it booted up as 32bit win7 and loaded the drivers.
this seemed to work until i tried to install a game and it crashed again all i saw was a quick message about "memory"
needles to say i have returned the g-skill ram as that was the only thing not in the mob recommended ram.
silly boy bought it for it's latency didn't read the small print.
I am with any ram now and I'm having difficulty finding somewhere that has a stock of recommended ram i.e.
Patriot PGS34G1600LLKA, GeIL GV34GB1600C8DC, or lots of very expensive Kingston. £100 is about my limit.
Any way that said, do you think i had another problem?
the mem i bought was GSKill 4GB DDR3 Dual Channel Memory Kit (2x2GB) PC3-12800 1600MHz (7-8-7-24)
Model Number: F3-12800CL7D-4GBRM
I hope someone can help
thank you

Blue screen like that sounds like RAM, or overclocking, or overheating,  I guess you are not overclocking.
I'm using memory modules "specifically designed for intel P55 chipset" (according to OCZ) on my AMD PC.  The only thing is that I had to set up the timings manually.  I was able to set up tighter timings because I'm running slower than rated speeds (at 1333 MHz instead of 1600 MHz), no problems whatsoever.  But I'm not saying that the GSkill RAM that you bought would definitely work though, incompatibility problem is still possible.  I bought my RAM at a local store, so its easy to return it if it didn't work  
So, apart from incompatibility, either the timings or speeds were not correct, or you had some defective RAM modules.  Need to run memtest on them to find out.  Also, Phenom II normally accept maximum RAM clockspeed of 1333 MHz, if you set up the RAM to go 1600 MHz that is considered overclocking and may not be stable.
This is the favorite line in this forum:  Check your power supply!    A weak power supply may cause problem as well.
Also try using single card before you do SLI when installing.
Good luck!
