    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.

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

    thanks... certainly not bad even for 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.

    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

    • WinXP Pro SP3 full nLite updated hotfixes / Windows 7 beta dual boot

    Off topic dude.
    Though the other night a guy explains CAS 7 1333mhz DDR3 will @ to 1600mhz.
    Do you know of this/seen on here or your forum?
    Have you seen other enthusiast use 3 different sets off ddr3 on a i7 mobo at the same time. CAS7 is sweet.. But you always have CAS7 sets.....
    Thanks evs...:cool::Paranoid::D
    Still cant find Cellshock PC3-14400 on SI or PS...

    No retailer in OZ stocks Cellshock brand, best to try from Europe at memoryc.com

    As to DDR3-1333Mhz modules capable of DDR3-1600 8-8-8-24, all modules listed on my short list at http://i4memory.com/f83/eva2000s-ddr3-triple-channel-memory-kits-short-list-14047/ will be able to do that at least :)

    I've probably only seen one or two folks mix modules like me but that was for 3x1GB or 3x2GB, not 6x module config like I did above :)

    Do you know where they get the RAM from?

    Funny, very close to my place. But I was asking for the memory chips. This company is for sure not producing the chips by itself, or?

    Eva, are you kidding me? ;) You know why I ask that. If we know the RAM "chip", it might be possible to identify the modules from other brands that come with the same. For sure Micron is not only selling these chips to Cellshock.

    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 :D ;)

    "edit on reply to ram list..


    But be sure they are the exact rev...
    The DDR# list is of latest updates. Which is good. So trust in them...
    Bravo to Samsung as they are in THE GAME:)

    Hey eva, do you mind testing out a ram timing configuration for me on your system?

    Edit: With everest, if these settings work, latency should be reduced in theory.

    Bios Settings;
    System Memory Multiplier: Auto
    Ram timings: 6-6-6-14
    DDR3 voltage: 1.80+

    The rest of the settings should be fine as long as the memory frequency doesn't exceed what your minimum ram specifications are.

    without testing i can tell you if you kept same memory frequency but 6-6-6-x timings of course latency will be faster :)

    I'm not testing this mixed config now, moved onto my first 3x2GB triple channel kit now
