Both links lead to the same Corsair RAM.
Do you mean this:
Kingston HyperX Genesis 12GB (3x4GB) DDR3 PC3-12800C9 1600MHz Triple Channel
You should be able to use all 6 sticks together for 18GB.
The tRAS on the Kingston is slightly higher so you may need to run all 6 sticks at the Kingston timing.
Filling all 6 RAM slots can affect the overclock settings but you won't know until you try it.
You may need to settle for a slightly lower overclock or tweak some settings for what you have now.
You have Windows 7 Ultimate (I assume 64 bit) so you'll be OK with more than 16GB of RAM.
and win 7 professional at 64 bit so yes that'll utilize over 3.5gb RAM.
and it's the X58A not the EX58![]()
How much of an improvement would i notice with my rig if i installed 8 or 16gig of 1600mhz DDR3 compared to the 8gig of 1333mhz i currently have installed.
Your sig. say Ultimate.
Even with 64 bit the Home Premium Edition can only use 16GB.
I realised.
That's why I edited the post![]()
And it's the professional edition so i think it has the same limits as ultimate.
