How Much Memory?

I want to upgrade the RAM in my computer and want to know how much I should get, 6gb or 12gb? I have a i7 920, not oced, a gtx 460 and I will probably be buying another for sli. I have a 750W psu if that is relevant. My OS is Vista 64 bit and my motherboard supports triple channel memory. So I'm trying to decide between 6 gb's (3x2) or 12 gb's (6x2). The main use of this computer is gaming. Any input is greatly appreciated.

  1. Hi.

    6GB (3x2GB) is more that enough for games. What budget do you have for the RAM? What mobo do you have?
  2. Hey Saint, TY for the response.
    My motherboard is this: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131346
    It has triple channel memory banks and currently I only have 3 gbs (3x1) which doesn't feel like enough, especially since I'm running Vista 64 bit. They no longer make the memory I currently have, so I decided to replace it with either 6 gbs (3x2) or 12 gbs (6x2). I read http://www.tomshardware.com/reviews/ram-memory-upgrade,2778.html and they recommend a minimum of 8 gbs. I don't think that is possible in triple channel set up is it? My impression is I need to have 3, then 6, then 12 as my options for increasing RAM. So my question is it worth it to have 12 gbs over 6? Budget wise is I can afford 12 but don't want to spend money for the sake of it if that makes sense.
  3. Correct, 8GB isn't possible in tri-channel.

    This 6GB kit is very good and with excellent price: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231335&cm_re=PI_1600-_-20-231-335-_-Product
  4. You 'can' use 2 Kits of 2X2GB - it will work - but you're SOL to fill the 2 slots. I recommend a single kit of 3X4GB if 8GB is the goal; Tri Channel is more efficient than Hexa Channel.

    4-Correct Choices:
    2 kits 2X_GB
    2 kits 3X_GB
    1 kit 2X_GB
    1 kit 3X_GB

    BAD Choices:
    1 or 2 kits 2X_GB + 1 or 2 Stick(s); pseudo Tri Channel
    1 kit 3X_GB + 1 kit 2X_GB
    etc..
  5. Performance wise, what is the difference between DDR3 1333 and DDR3 1600? And also are certain timings better than others?
  6. Anywhere from ±2%~±5% and I do mean the minus (-) RAM is all about the ICs used, the tightness of the CAS, etc. Benchmarking is the only way to know 100%. Not always but enough of the time you get what you pay for...

    Comparison Module #2: G.Skill Pi Series 7-8-7-24 1600MHz
    Comparison Module #3: Mushkin 998687 8-9-8-24 1866MHz
    Comparison Module #4: Corsair Dominator TR3X6G1600C8D 8-8-8-24 1600MHz
    Comparison Module #5: Kingston HyperX T1 9-9-9-27 1600MHz
    Comparison Module #6: Mushkin Blackline 998677B 7-7-7-20 1333MHz
    Comparison Module #7: Patriot Viper II Sector 7 9-9-9-27 1800MHz
