DDR2 800 or 1066 for a C2D 8X00?

The question is simple: what should i get for my new 8X00? I've looked thorugh some benchmarks and there isn't a big difference but still not convinced.

Money is not an issue as the price difference is around 20€..

thanks.

  1. DDR2 800, because :

    1_The difference isnt much
    2_DDR2 800 will OC very well just like 1066
    3_ DDR2 is cheaper
  2. very convincing... another question...how do your OCZ Reaper perform?

    thanks
  3. No problem

    I love my OCZ REAPER, i have 4x1GB of them and they are ver good
    i have my E6600@ 3.2 with 4-4-4-15 timings(For RAM) and its stable :)
  4. Well, test out the benches for PC8500 and PC6400, the writing speed difference are quite substantial. Like over 25% difference. Reading, no, but writing and copying, yes.

  5. ^^^The benchmarks were all for DDR2 800 that was overclocked and showed no substantial difference between 800 and 933 that they tested. The read/write benchmark was for the same memory that changed little as frequency increased. The difference between Reading and writing is substantial.; The read/write performance between speeds is little/none.

    IMO, 1066 at this point in the game is a waste of money.
    Better timings and better price with good DDR2 800

    Sorry, I shouldve included a PC8500 review. Here it is:

    http://www.cluboc.net/reviews/memory/crucial/ballistix_tracer_pc2_8500/p3.asp

    The PC6400 under sandra were around 5600MB/s.
    The PC8500 is over 8000MB/s.
    Just by the maths, thats a 30% difference in performance.

    I've read, but not independently confirmed,
    that some PC2-8500 is just overclocked PC2-6400.

    Also, some PC2-8500 SDRAM uses Micron chips,
    and others do not.

    I would look first for PC2-8500 made with Micron chips
    that run at 1066 natively, not with overclocking.

    www.anandtech.com is another good source of
    reliable, objective comparisons.

    Crucial Ballistix Ram uses Micron chips. They might be overclocked PC6400 but they sure do perform like they are suppose to at 1066 or higher.

    Now you can get 2x1gb for $65 on Newegg after rebates! Damn cheap.
  8. In short, for the $20 difference, get the PC8500. It's guaranteed to be as good, if not a better IC than the comparable PC6400. And, regardless of brand or IC, not "ALL" PC6400 will OC well. And, with the FSB speeds the 8*** Intel CPUs are hitting, you should go well past DDR800 if the rest of the system is up to snuff. You can even find some 2 x 2gb PC8000 or PC8500 kits for very reasonable prices if you need that much memory.
  9. Check out my Ballistix Tracers compared to a DDR3-1600. Minimal difference in performance, dramatic difference in price.
