Question about mixing DDR3 for a beginner

Hey, I looked in a few topics and I was wondering if someone could help me. Currently, I have a this: in my desktop, however I only have two of the sticks in it. (The third stick was damaged) With my Core i5 750 system running Windows 7 x64, I feel I need more memory so I was looking at buying some additional RAM. My question is would it be ok to mix this: with my older two sticks? (For a grand total of 6GB or RAM.) They look to have the same specs with the exception of the manufacturer... or would it be better to just start out fresh with a new memory set? Or is 2GB sufficent for browsing the internet, music/movies, and light gaming and video editing?

  1. Welcome Newcomer! :)

    I understand your reasoning but I all too well have seen the consequences. So to answer your question not knowing more {e.g. MOBO}, they are different DDR3's, speed 1333 vs 1866 and type dual vs tri channel purposed - so my money is a NO.

    Possible? ~ slim to none, and at best would operated at the lowest common speed of 1333 MHz.

    The best practice is not to mix DDR, and to either use RAM that is Certified via MOBO Mfg or Tested via the RAM Mfg. In addition, they need/should be "matched" - Speed, CAS {9-9-9-24}, Voltage, type DDR2/DDR3 Dual/Tri channel.

    BTW - most of the DDR's carry 3-5+ year warranties, and I'd return {RMA} the "damaged" DDR.

    Good Luck!
  2. Thanks for your help! I bought a whole new set of DDR3 and I'm looking into RMA the other set.
  3. lol

    The RAM can works without problem but at the lower speed that is 1333 IMO u don't need buy the other kit since both have the same timings.

    Just my two cents.
  4. @ saint19 - They have different timings, different speeds, and different controller - lets see your scrambled eggs DDR3 rig. Post a CPUz! Stated "Possible? ~ slim to none"

    Show me your "working" & "unstable" & "Goofy" setup! Please!

    9-9-9-24 @ 1333 & 9-9-9-27 @ 1866 + Different Controllers!

    MAJOR LOL!!!!! HA!! SHOW ME! Then run a Bench with {DDR3} "Normal" & "Goofy" then maybe lets see 10+ hours of Prime95.

    If I hated the OP and/or wanted them to have "goofy" issues with their rig then I would have been like your suggestion - "YES"
  5. IMO

    U don't read that? The OP make her choice at the best option like I say was IMO and u can go to and look for my profile. My current mobo "don't support" my RAM speed.
  6. IMO
    You have clean Crucial Ballistix Tracer and not mixed with Patriot G Series 'Sector 5' Edition; Huh? - IMO support RAM speed duh OC whoopee a Newbie can OC DDR. No mention or search results @ + saint19

    I not you gave the OP the "Smartest" advice. 8238 posts = Bronze?! It took me ~ 425 = Bronze.
  7. Mix RAM is the same that install RAM in a mobo that "don't support it".


    Obviously we don't have the same opinion about this so forget it even the OP RMA the RAM and get a new one.
  8. Again, there's no mixing of RAM on your rig. Never on any of mine. Interesting CPUz overlooked your "matching" DDR.

    I wonder what the person that I'm building SR-2 rig would think if I did something like this (^) to their $12K investment??!! There's no difference right is right, and I did right. You Jerry Rig other people's stuff w/o a thought...hmmm?
