    Talking 6x1GB Corsair + GSkill + Cellshock (HCF0 + D9GTR) combo !

    First time mismatched 6x1GB triple channel. Still manages to accomodate my push 120x38mm thick Scythe UltraKaze 2000rpm fan with memory module installed in dimm slot 1

    System specs
    • Intel Core i7 920 3836A756
    • Thermalright Ultra 120 Extreme + LGA1366 Bolt Thru kit + 2x 120x38mm Scythe UltraKaze 2000rpm 87cfm fans in push/pull
    • DFI LP UT X58-T3EH8 R.A51 - 01/23 beta bios
    • 128MB Gainward FX5200 PCI
    • Ram cooling: 3x 60x25mm Sunon 23.5cfm Maglev fans
    • 80GB Hitachi 7K80 SATAII
    • Pioneer DVD-RW
    • 1KW Corsair HX1000 psu
    • WinXP Pro SP3 full nLite updated hotfixes / Windows 7 beta dual boot


    Memory configuration:
    • Dimm slot #1: 1GB G.Skill PC3-12800HZ (Samsung HCF0)
    • Dimm slot #2: 1GB Corsair DDR3-2133C9DF Dominator (Samsung HCF0)
    • Dimm slot #3: 1GB Cellshock PC3-14400 (Micron D9GTR)
    • Dimm slot #4: 1GB Corsair DDR3-2133C9DF Dominator (Samsung HCF0)
    • Dimm slot #5: 1GB Cellshock PC3-14400 (Micron D9GTR)
    • Dimm slot #6: 1GB G.Skill PC3-12800HZ (Samsung HCF0)






    Seems with 6x1GB AUTO CMD rate = 2T, so for 1T you need to change CMD rate from AUTO to 1T (1N).

    Bumped vdimm straight to 1.830v in bios and clocked 6x1GB straight up to DDR3-1606Mhz 8-8-8-24 1T to see how it runs. Everest latency speeds seem to get slower as you add more modules. So in terms of fastest everest latency the order goes = 2x1GB > 3x1GB > 6x1GB. Still 32M time with 6x1GB DDR3-1606Mhz 8-8-8-24 1T is pretty decent.

    6x1GB @DDR3-1606Mhz 8-8-8-24 1T at 1.830v bios (DMM measured 1.835v real)

    6x1GB @DDR3-1688Mhz 8-8-8-24 1T at 1.815v bios (DMM measured 1.820v real)

    Bumped Bclk to 211 and reduced vdimm from 1.830v bios to 1.815v bios (DMM = 1.820v real) for DDR3-1688Mhz 8-8-8-24 1T.





    Slightly faster 32M Pi times than 3x1GB D9GTR at same main timings even though below 6x1GB was done with considerably looser subtimings for tRFC, tWTP, tRRD and tFAW in bios. Will try tighter timings later.



    Everest SPD and bandwidth

    Nice Info, thanks, also that is a sweet setup, plus it's nice to see the ram playing together. So as far as ram latency, if i'm looking to drive some 1M superpi results it's best to use 2x1G /\?

    thanks.. everest latency doesn't translate much for super pi for i7/x58 it seems if you compare different configs 2x1GB vs 3x1GB..

    but does translate properly for same configs so 3x1GB vs 3x1GB lower latency = better pi times in general

    The board looks like Frankenstein's monster with all that mismatched memory

    That mismatched ram looks hilarious. Nice to know it all plays well together though. Wondering if this would also be ok on other boards too or just the DFI. Was the SPI32M time a little faster than with the 3 x 1GB GTR due to the fact the first module (HZ stick) has tighter SPD settings for timings not controllable through bios?

    Sure is a monster how about 879Mhz 8-8-8-24 1T at 1.815v bios!

    Not sure about other boards, but could be cpu IMC related or DFI UT X58-T3EH8 helping the cpu along.

    I think all slots populated usually gives best 32M times clock for clock same with 965P/X38/X48 just usually on those platforms 4x dimm usually can't keep up with 2x dimm clock wise. i7/X58 might be a different story

    Best I can do keeping voltages the same @879Mhz 8-8-8-24 1T at 1.815v bios (1.820v real)

    how about CAS7

    6x1GB 7-7-7-18 1T

    Seems this mismatched combo does pretty well tightening both main and subtimings managing up to DDR3-1718Mhz 7-7-7-18 1T at 1.875v bios. Needed a notch or two higher vdimm when subtimings were tightened otherwise I could of lowered vdimm by ~0.25-0.30v.

    Max 6x1GB 8-8-8-24 1T Clocks

    Changing to 10x memory multiplier, tried to find max 6x1GB 8-8-8-24 1T clocks and ended up with DDR3-2000Mhz 8-8-8-24 1T at 2.04v bios (2.045v real) only for tried 1M Super Pi as 32M Pi test failed. I dropped bclk and mem clocks to DDR3-1960Mhz 8-8-8-24 1T at same vdimm but Super Pi 32M failed at 22nd iteration. Similar trend occured at DDR3-1940mhz as well.

    I recall it's probably the Cellshock PC3-14400 Micron D9GTR holding the 6x1GB modules back as it needed more vdimm for do such clocks even on P35/X48 DDR3 boards closer to 2.1+ volts for around DDR3-1920 8-8-8-x. Decided to stop there as unnecessary stress to i7 IMC ain't needed when I shall have some nice DDR3-2000 CAS7 rated triple channel memory due my way this coming week
