Ram debate

system
AMD Phenom II X4 965 Black Edition
ASUS Crosshair IV Formula 890FX Chipset

ram:
Kingston HyperX Blu DDR3 4GB single1600MHz CL9 DIMM
product code - KHX1600C9D3B1/4G
i have one of these so far and looking at buying another for dual channel

and

G.Skill Flare [ FLS ] F3-14400CL9D-4GBFLS (2Gx2)
http://www.gskill.com/products.php?index=272

which runs at 1800mhz

since i have 4x dimms on the board i figured i should put both sets of ram in.but is it worth the downclock?
i could oc the ram aswell and planning on oc'ing the whole set.
any advice?

  1. Interesting. Is having 16 GB of ram more important than being able to run the ram at 1800 MHz. I would say the difference between 1600 and 1800 MHz is negligible, so you're better off running all the memory, even though some of it will be downclocked slightly.
  2. Best answer
    With four DIMMs the BIOS will downclock all of the RAM to the default frequency of 1333 Mhz. --- assuming the DIMMs will actually function together as a non-matched set with out issues -- which is a big assumption. You won't be able to OC the RAM with four DIMMs installed.

    If you want to run a lot of or large apps like CAD, etc. then more than 8 GB. RAM might be of value. If not then 8 GB. is plenty. OC'ing the RAM makes less than 1% diff in system performance in my testing.
  3. would it not just downcloack to 1600?

  5. No it would not downclock to 1600 because the default frequency for your CPU to RAM frequency is 1333 Mhz. not 1600 Mhz.
