Ga-970a-ud3 and 1600 ram

[myles42]

hi to all. first time user here but fairly well versed with building up hardware.

i have just build a machine with a ga-ud3a-ud3 rev 1x, using 4 x 2gb sticks of g-skill ripjaws for my ram, they run at 1600mhz as stock.
when i did the initial win7 instal, it instaled 1st part ok, but when it rebooted, it would not start up on the screen. i had to poer it down by the button.i used xms3 ram as i had a hunch it was a ram issue. it booted up straight away but i have had to downgrade to ddr3 1333. i dont overclock, i like things to run at intended stock speeds.
im using the phenom ll 965 cpu. although this is a 970 chi, im a bit annoyed as i took out my newly aquired asus m5a99x-evo board because i didnt like the temps it was pushing out. it has the first f1 bios still, i dont beleive bios update will fix it as i dont like doing that although to be fair, gigabyte's bios update naver failed me in the past.
i have a spare fx4100 cpu but cannot fit it to this board without updating the bios.
the ram is f3-12800cl9d-4gbxl
thank you in advance to you all.

First, running 1600Mhz RAMs at 1333Mhz is not overclock.. (underclock maybe, shouldn't rise up cpu temps)

What temps you're getting?

ben, you didnt read my post, i never mentioned that dropping ram speed is overclocking, i know its underclocking. on the gigabyte board i have low temps which is good, my asus boards runs at temps of around 60 degrees standard. is this a 990fx heat issue on the chipset do you think.
