    [XF] GeIL DDR3-1066 CL6

    Two days ago, XF Team had brought you Team group DDR3-800 sneak peak.
    Today, let's do some DDR3 overclock with GeIL DDR3-1066.

















    This time, GeiL had used Elpida DDR3 component with yellow heatspeader.
    However, It is still engineer sample.


    GeIL DDR3-1066 CL6 OC@1500 CL7

    CPU-Z is still unable to read and support this DDR3 motherboard. Franck is updating codes now. Once we could get a newer version. I will upload a correct read of CPU-Z screen shot.

    Getting excited! Can I ask what motherboard you're using?

    You have to admit though, PC8500 at 6-6-6 isn't exactly ground breaking

    I don't now if it's a question under NDA, but when the DDR3 will hit the market? Q3 2007?

    Thanks.

    For early DDR3 it's pretty good. Standard DDR3 with 6-6-6 timings runs at 400MHz (PC3-6400).
    Don't confuse this with DDR2. You should compare it like this:

    PC2-6400 (400MHz) with a CAS of 5 (like early DDR2)
    1 clockcycle equals 1/400,000,000th of a second or 2.5ns (nanoseconds)
    A total latency of 5 × 2.5 = 12.5ns

    PC3-8500 (533MHz) with a CAS of 6
    1 clockcycle equals 1/533,000,000th of a second or 1.875ns
    A total latency of 6 × 1.875 = 11.25ns

    As you can see the DDR3 module has a lower latency. But that's not even the most important benefit. The real benefit lies in the bandwidth.
    DDR3 will scale all the way up to PC3-12800 (12.8GB/s) and even further. The highest DDR2 ever managed was 11.7GB/s and that's DDR2 at 732MHz (PC2-11712).

    Thanks r00n, that actually clears up a lot. I really appreciate your time/insight. I guess that in time, DDR3 will REALLY start to show its benefits.

    the PC3-8500 is about equal to what PC2-4200 is. From what I've read from Micron there will be a Jedec spec for DDR3-1600

    PC2-4200 CAS3 has a latency of 11.25ns (3 × 3.75ns), which is indeed equal to PC3-8500 CAS6.
    This is logical, because both the clockspeed and the CAS are twice as high, so they even each other out.
    But the difference is that the DDR3 module has double the bandwidth (8500MB/s vs 4200MB/s).

    From what I've read from Micron there will be a Jedec spec for DDR3-1600
    Correct. That's what I meant when I said 'DDR3 will scale all the way up to PC3-12800'. 12800 ÷ 8 = 1600.

    LOL i read the title wrong! I THOUGHT it said DDR 1066 CAS 3!!!! I was like holy crap!!! But then i saw thats its DDR3 and cas 6 (yuck) Nevertheless though, muct be cool to get ES of sweet new HW. Only 1.5V too, neato. Now if only video cards would follow the less power trend....

    simani, out of curiosity, what is the lowest cas latency that the motherboard supports? I'm assuming cas4, but i haven't read through the ddr3 tech docs, where my answer will be easily found
    Got a fan over those memory sticks? No? Well get to it before you kill them

    It depends on what board it is. The first boards are going to support both DDR2 and DDR3 so it technically could have CL3. I believe though the lowest Cas latency supported by DDR3 is 5.

    I did NOT know that! I'm sure a few others don't either. thanks for the quick explanation yo

    Yes you are right, Q3 2007 or even earlier like end of May.

    According to Samsung model number M378B65EZ-CG9 ( DDR3-1333 module) SPD spec. CL options are 5,6,7,8. However, you are right about CL that motherboard support is CL4.

    the voltage was 1.7v. no tweak at all.

    I was talking about a single DDR2 and DDR3 memory module, without Dual Channel and Bank Interleave.

    Same question , if OS wasn't tweaked we have new platform for 32M .
