    Cool 4GB A-DATA 2000X + DFI DK P55-T3EH9 CAS8 fun!

    Finally my turn to play with DDR3 modules on P55 - can't let you guys have all the fun! I bought 5 sets of 4GB A-DATA 2000X a while back tested them first on Asus P6T6 WS Revolution http://i4memory.com/f83/12gb-data-20...testing-20350/ and all either did DDR3-2000Mhz 7-8-7-24 1T or 7-9-7-24 1T at various voltages in 2x2GB and 3x2GB and 6x2GB config, but seems they behave differently on DFI DK P55-T3EH9. That or I have yet to master P55 chipset tweaking










    System:
    • Intel i5 750 L925B626
    • Corsair H50-1 s1156 H20 + stock 59cfm Corsair fan (pump on cpu fan header, fan on cpu_pwm fan header)
    • DFI LP DK P55-T3EH9 12/08 beta bios
    • 128MB Gainward FX5200 PCI video card to start with
    • 2x2GB A-DATA 2000X dual channel kit #4 (modules 7+8)
    • 640GB Samsung SATA
    • Pioneer DVD-R
    • 1KW PC&C Quad SLI psu
    • Additional cooling: 120x25mm Spire 75cfm fan over cpu socket/pwm area and 60x25mm Sunon 23.5cfm fan over PCH chipset heatsink


    4GB A-DATA 2000X Kit #4
    CAS 8 Overclocking Tests - Round 1

    For CAS8 clocks on kit #4 definitely better than kit #5. But still DDR3-2000Mhz 8-8-8-24 1T has minor errors on DFI DK P55-T3EH9 even though same kit #4 on Asus P6T6 WS Revolution did DDR3-2000Mhz 7-8-7-24 1T at 1.58v ??? Weird ? Could be board/bios related or just my i5 750 doesn't like 7-8-7-24 on these modules than much ?

    Strangely for kit #4 finding 8-9-8-24 clocks a bit easier to clock than 9-9-9-24 ?

    2x2GB A-DATA 2000X dual channel Kit #5 modules 9+10
    • on Asus P6T6 WS Revolution did DDR3-2000Mhz 7-9-7-24 1T at 1.60v
    • on DFI DK P55-T3EH9 does
      • DDR3-2000Mhz 8-9-8-24 1T at 1.264v CPU VTT at 1.66v (4x 32M) - loosen tRFC 110 and tFAW 37 and tRRD 5
      • DDR3-2168Mhz 8-9-8-24 1T at 1.342v CPU VTT at 1.78v (single 32M) - loosen tRFC 110 and tFAW 37 and tRRD 5


    2x2GB A-DATA 2000X dual channel Kit #4 modules 7+8
    • on Asus P6T6 WS Revolution did DDR3-2000Mhz 7-8-7-24 1T at 1.58v
    • on DFI DK P55-T3EH9 kit #4 scales with just CPU VTT more than Kit #5
      • DDR3-2008Mhz 8-9-8-24 1T at 1.264v CPU VTT at 1.58v (4x 32M) - tRFC 74 and tFAW 20
      • DDR3-2108Mhz 8-9-8-24 1T at 1.282v CPU VTT at 1.66v (4x 32M) - tRFC 74 and tFAW 20
      • DDR3-2194Mhz 8-9-8-24 1T at 1.282v CPU VTT at 1.70v (4x 32M) - tRFC 88 and tFAW 30

    Nice findings about scaling kits with vtt

    I am looking to future results. Personally I don't like P55 platform but I am going to test some soon.

    Very nice results, thanks for sharing! Looks like 4GB modules clock nearly as well as 2GB ones!

    I'd suggest for you to get your hands on i7 860/870 to be able to utilize 2:12 divider
    It'd help you out with higher mem clocks

    ***just my 2cent ***

    thanks... should have better results as i figure out the p55 system voltages/settings

    it's 2x2GB not 4GB modules

    yeah i5 750 stuck with 10x mem multi but i'm confident I can squeeze out more on this i5 750 as soon as I'm more familiar with the settings

    first wall broken

    DDR3-2274Mhz 8-9-8-27 1T at 1.72v

    Loosened timings alot more, pushed voltages a bit more and dropped QPI frequency from 4.8GT/s (18x multi) to 4.27GT/s (16x multi) to achieve my highest frequency so far for bclk 227bclk as well as for memory frequency @DDR3-2274Mhz 8-9-8-27 1T at 1.72v validation and @DDR3-2247Mhz 8-9-8-27 1T at 1.72v for Super Pi 1M.

    4GB A-DATA 2000X Kit #4
    CAS 7 Overclocking Tests - Round 1

    Now to CAS7 timings for 2nd kit #4. The same trend continues, kit #4 has better CAS7 overclocking headroom than kit #5. Goes to show not all memory are created equal

    Kit #4 managed DDR3-1948Mhz 7-8-7-24 1T at same settings and same 1.70v vdimm which is much higher than Kit #5's max DDR3-1834Mhz 7-8-7-24 1T at 1.70v. But kit #4 like kit #5 didn't scale any higher with loosened tRCD of 9 or 10 (7-9-7-24 or 7-10-7-24).

    System:
    • Intel i5 750 L925B626
    • Corsair H50-1 s1156 H20 + stock 59cfm Corsair fan (pump on cpu fan header, fan on cpu_pwm fan header)
    • DFI LP DK P55-T3EH9 12/08 beta bios
    • 128MB Gainward FX5200 PCI video card to start with
    • 2x2GB A-DATA 2000X dual channel kit #4 (modules 7+8)
    • 640GB Samsung SATA

    • Additional cooling: 120x25mm Spire 75cfm fan over cpu socket/pwm area and 60x25mm Sunon 23.5cfm fan over PCH chipset heatsink

    Hi Eva

    My result from A-Data 2 x 2GB 2000 CL9 with 1.66v I'm not push too mouch vdimm for this kit, because my first kit go away with smth like 1.72v. Some 3D, and 32M :







    For 32M only single core, because this cpu is realy crap


    Life sometimes gets in the way of what we want to do.
