    OCZ TCC5 Overclocking Results?

    I've been tuning my OCZ Platinum Rev 2 v1.1 TCC5 and was wondering if anyone had timings/results to share?

    I've been testing for 5 passes of Memtest #5 till I find the max so I can test at 95% of max for 50 passes. So far I'm at 305MHz, 2.5-4-6-3-8-15-3-2-1-2-3072-1-E-A-0-7-2-8-5-A-D-16-7-D. Memory bandwidth is around 3470MB/s at 305x9. LDT=1.4, Chipset=1.6, DRAM Voltage = 2.9+0.3

    I've written down every tweak and its result but it's at home. For some reason I get more errors with trfc=16, twtr=2, or tref=4708. R/W Queue Bypass at 8x or Bypass Max at 4x doesn't seem to make a difference and 2.93V gives me the least amount of errors. I'm using BIOS 414-3, and have a 90mm fan sucking air from RAM, 80mm fan blowing air to RAM & mosfet.

    No one?

    Well I had DDR600 passing 100 test #5, 30 test #8, and 5 full tests. However I get errors at 120% and 126% using Memtest 3.2 in Windows while testing 800MB of RAM!

    DFI Settings:
    BIOS 414-3
    Vdimm=2.9V+0.3V
    LDT=1.2
    2.5-4-6-3-7-15-3-2-1-2-2-3072-1-E-A-0-7-2-8-5-A-D-16-7-D

    I got more errors with:
    LDT=1.3 or 1.4
    Vdimm increased beyond 2.93
    tras to 7
    twtr to 2
    trp to 4!

    Hopefully someone can share their OCZ timings?

    Flash to 510-3
    Start low and go high... my OCZ does 300 at 2.93, but it also does it at 2.75..
    Keep LDT as low as you can, although I usually keep mine at 1.3
    Use Tref of 3072 as a general value
    Use that thread for all the timings you could shake a barn door at
    Also, use Bleeding Edge forums, OCZ's official forums

    Using 5/10-1 bios. Can do 25 passes memtest 5 & 8 at 280 2.5-3-3-8, but fail prime and have errors in windows memtest. Can benchmark fine though. Even at 2.5-4-4-8 still not 100% stable. Also can bench 9x300 2.5-4-4-8. Highest 100% stable for me is 275 2.5-4-3-8@2.9v. Currently running 24/7 with 265-2.5-3-3-6 @ 2.8v. LDT 1.2 NB 1.6 Bios settings-2.5-3-6-3-7-12-2-2-1-2-2560-A-E-A-0-LV 7- LV 2-7-5-Fast-16-D-16-7-D Going trcd of 4 at 275 is no faster than 3 at 265, so running that with less volts. Have tried everything to get 280 100% stable, but just don't think it's possible with this set.

    This is my highest oc, 282 1:1 2,5-3-3-6 1T @2.75v (fan on top).
    Either my memory controller or chipset doesnt like higher stable clocks.

    try ocing with mem divider to see if your mobo is limiting factor.

    Well, i purchased a DFI nF4 Ultra-D and a new PSU.
    Finally im able to max the memory clocks. 320x8 2,5-4-3-7 1T 1:1 @2.9v.
    At this point Memtest stable. Next i will prime to find my best configuration.
    Clearly comparable to TCCD modules.

    (bandwidth is lower than normal due to 8x multiplier).

    BioPC, what board and psu were you running before? Are you saying that you tried these ram chips with a different board and got much higher with the DFI and a new psu?

    Wow nice clocks BioPC and Eldonko! I can't pass 1st pass of Memtest #5 at 305. BioPC could you post the rest of the timings you used?
    Eldonko, which 166Mhz Tref did you use in the BIOS?
    Thanks

    Thanks. I have a table printed off at home that shows what each tref in tweaker corresponds with in the BIOS but I'm at work and don't have it with me atm. If you have one just look up 166Mhz 1.95us.

    Tried 5/10-3 and 5/10-2. With 5/10-2, managed to get 9x295-2.5-4-3-8 to pass 32m of super-pi, but not prime stable. It's still over 20 seconds slower than 10x265-2.5-3-3-6, and that is completely prime stable.

    Eldonko - San Diego @ 2768=307*9 - 28m20
    4X4N - Venice @ 2655=295*9 - 28m47
    My results (amrgb): Winchester @ 2620=291*9 - 27m40

    Or the new A64 cores are slower than the older ones in superpi 32M calculations or you need to tweak further your memory.

    Specially Eldonko's results seem too slow compared with mine.

    GSkill 4400 LE, 440 TCCD chips.

    The max I got so far with 2-5-3-3-6 was 298 but I've not tweaked thoroughly because this fsb has no use for me. I'll post the pics later.

    EDIT: damn, it's always the same thing. When we want to repeat a result we can't.

    Nice results amrgb Just ran 10x265 2.5-3-3-6 32m pass again. I was wrong, it's 30 seconds faster. Same cpu speed. Having to loosen timings to get 295 is not worth it. Just wish I could get 280 stable with same timings, then I could keep my cpu at 2.8.

    Yeah I think I need an OS formatting or something, my SuperPI times have been super slow the last few weeks. I was getting 26m20 at 2810/255 2.5-3-3 a while back, now with better clocks I get worse times.



    This thread isn't a competition for the fastest SuperPI times though, its for max TCC5 OCs.

    Could you guys post ALL of your DRAM BIOS settings instead of just like 2.5-3-3-7??? There are way too many settings on the DFI boards and it would be helpful to all of us. Thanks.

    I can memtest at 300 also. Lets see some windows memtest or 32m of super-pi.

    @smellyfatchick:

    I had a Neo2 not stable over a 280 fsb and my old 400W psu had a weak 12v line.
