    Hmmm...never saw this before. As far as I am concerned, op's findings are still true. At least with the same set of RAM I have been using. Time to scour the interwebs for moar oc comparisions.

    For everyday use, I'd be a little worried too. The rated vCore max is 1.375 for the 930 so I'd keep it to that or slightly higher for everyday computing. 1.4 is about the maximum I'dsay without extensive Overclocking experience. Keep an eye on your temps. Might try lowering the the vCore some and raising the QPI/VTT a little to help cut the vCore voltage

    memories like the corner of my mind

    anyway this is my setup and i'm probably not in the right spot, first post. ga-ex58-ud5-930 cpu- 8 gigs g.skill f3-16000cl9d-4gbpi-b- 3 480 cards in sli of course. Finally got this ram to run at rated speed 2000mhz with the 930 oc to 4.0 finally but i'm a little scared of the voltage on my cpu to get there. 1.44. had to raise votage on ram to 2.0 with a 9-9-9-27. Now it's been running pretty stable for a couple of weeks now. only thing my sleep mode hangs every once in awhile and sometimes i get green flashing bars on the screen for a couple seconds while playing games but other than that i'm pretty sastisfied.

    Thanks for good test

    Sometimes people are overwhelmed and sometimes people have a hard time taking anything on some of the gammer sites at face value. Sometimes people do not have endless hours pouring through questionable material.
    I'd rather rely on you the experts at my manufacturers site.

    My system has worlded flawlessly since Feb. I use it for photoshop and lightroom and not running endless benchmarks. I'm very happy with the gskill product.

    Some times people rather not read, let alone do research, they just want somebody to tell them.

    Some enthusiasts claim that because they can't run faster ram at the rated speed, that the same ram will actually perform better when downclocked - and at tighter timings. While i'm sure maybe SOME rams might behave this way, most simply will perform best when clocked at a higher frequency.

    I've seen some benchmark's pulled off of Tom's hardware claiming that ram downclocked to 1600Mhz out performed the same modules clocked at 1800 and 2000. Let me just say I don't take much stock in benchmarks at tom's hardware- nor would I rely on them as gospel. I decided to run my own benchmarks, my own controlled environment, and use different software to confirm my results.

    The Test Conditions:

    - All benchmark's were performed right after a warm boot up.
    - Each test was performed 3 times, and the best result was recorded.
    - Bios was set manually, cpu clock speed remained the same, all volts remained constant.
    - Cpu/NB frequency remained as close as possible no more than 50Mhz difference.
    - Programs used were SiSandra, Everest, and Passmark.











    There you have it, proof that 2000mhz ram is fastest when ran at it's intended speed.
    Not only did it win all the tests, but it crushed the other speeds.
    read the article then you will know what best speed are for the ram :

    It's more the other way around, where the CPU overclocked better utilizes higher clocked RAM. Increased CPU and NB frequencies can drastically improve memory bandwidth.

    which current generation CPU's benefit from higher clocked RAM (increasing bandwidth) as the CPU is overclocked?

    Some in the past have not been bandwidth limited by the RAM and hence there was no point scaling your RAM up with the CPU speed.

    Nice to see simple well presented results too .

    I'm glad to find this resource. The rules have certainly been rewritten when dealing with the I7series of processors.

    I had always thought that the faster rated ram just passed more stringent tests within the series and that faster was always better. I'm building up a Ga-X58A-UD3R with an i7 950 & 12 gig of 1600mhz Ripjaw (12800CL9T-12GBRL) When I had a look at the POST and the bios and noticed the ram showing as 1066 and the cpu freq at 2.6 intead of 3.07.

    I had a look around and tried the intelligent tweaker and the ram read as 1600mhz but the timing was too low. I restarted the sytem and rechecked and the timing seemed to correct them self(9-9-9-24).

    I'm posting this so others are aware that this happens. After a while you get used to the quirks but any neophytes might have an anxiety attack.

    The processor spec clearly calls for DDR3-800/1066 but you can't find any where I live and the 3 sticks of 1600 mhz was actually cheaper than the 1333.

    I built an 1156 board up last month with an i5 and I've never had an issue with memory. Again I bought 1600mhz ram cuz it was cheaper.

    Looks like a good product and at a reasonable price

    The faster one of course, considering the BIOS can downclock it. On a desktop it is no question since you can overclock the CPU. But for laptop it's all preset, so nothing you can really do about it.

Both sticks were the same price at Newegg, so I figured why not get the faster memory? If I will have better performance with the native 1066 I will exchange the memory. Thanks!

    I don't think under 18000MB/s Read/Write it's even worth benchmarking at everest.

    You'll get clean 18K at around 8-8-8-24 at around 1840-1870Mhz with any decensy at Uncore + CPU. depending of board of course how high it goes.

    This is the slow version of usual clock at around 18500MB/s:


    -edit-

    hmm, mind remind everyone that above cannot be compared to 'AMD Phenom' benchmarks above as it's done with Intel's crappiest core I7-950 ever. ;P

    magnus is not banned, it was some other guy that asked magnus to use other programs to test. He was promoting the other programs..
