    Cool E6600 + Asus P5W DH Deluxe Adventures

    Intel Core 2 Duo E6600 Conroe + Asus P5W DH Deluxe


    Thanks to Asus, I finally got my hands on a Asus P5W DH Deluxe for the sole purpose of cranking out some nice benchmarks. This board is the newly revised P5W DH which later P5W DH Deluxes will feature a higher max MCH volts of 1.85v



    Full pictures:

    System:
    • Intel Core 2 Duo E6600 QPGE B1 Step 5
    • Swiftech G4 Storm water cooled cpu
    • Asus P5W DH Deluxe 0801 bios
    • 256MB BFG 7800GTX 84.66 SLI drivers
    • 2x1GB Gskill PC6400PHU2 2GBHZ Micron D9 (cooled by Sunon 92x38mm 120cfm fan on rheobus medium speed)
    • 74GB WD Raptor 8MB cache
    • FDD
    • 700W OCZ GameXStream Psu



    General observations and notes:
    • The setup and installation went problem free so started some stock load tests.
    • I read the guide to known P5W DH issues and workarounds at http://www.xtremesystems.org/forums/...d.php?t=110193
    • I followed the guide FCG wrote at http://www.xtremesystems.org/forums/...d.php?t=106563 for preparing the board by reapplying the TIM on the Northbridge/MCH and Southbridge heatsinks and removed their respectively covers to allow the actual heatsinks to breathe. I also added a 120x25mm fan over my video card which cools my SB heatsink and another 120x25mm fan over the NB and cpu socket area.
    • I plugged in my 74GB WD Raptor 8MB drive into the red SATA1 connector on motherboard as explained in the manual
    • Get use to the board auto shutting down on exiting bios, memtest or windows and automatically booting up again at speeds other than default 266fsb. Seems it's like Intel D975XBX Badaxe when changing boot straps. It's the boards way of ensuring the bios settings are properly set for booting. Can be quite annoying when rebooting windows when doing benchmark sessions. Actually, I got a reply from an Asus contact about the auto power down:
      This behaviour is caused by system's limitation. For over-clocking, the
      internal PLL of NB would not lock on the high clock right away, so that means
      system could not hold on the clock frequency immediately after reset. That's
      why we add a auto-power down scheme to fix this issue. Of course, this
      behaviour only occurs at over-clocking scenario.
    • Seems AI Booster under reports cpu temps by around 8-10C. Coretemp app reports stock cpu idle and load temps in line with what my Intel D975XBX Badaxe Rev304 motherboard for this Core 2 Duo E6600 Conroe cpu.
    • AI Booster loads awfully slowly and like Asus Probe II app both consume too much memory when open for my liking >10-12+ MB per app!
    • AI Booster has a habit of not displaying the right temp with occassional jumps to 255C.
    • AI Booster reported memory voltage is inaccurate i.e. 2.1v in bios = 2.2v in AI Booster, 2.2v in bios = 2.3v AI Booster, 2.3v bios = 0.00v AI Booster, and 2.35v = 6.54v in AI Booster!
    • In bios monitoring section it can momentarily freeze or hang on you, no one knows why but if you wait a tad longer it will function fine and no probs. Just another issue to get use to.
    • The board does droop alot more than Intel D975XBX Badaxe (which was fairly stable on vcore when Enhanced Power slope was enabled). P5W DH doesn't have such a function to reduce drooping on vcore voltage. There's around ~0.03 to 0.05v vcore droop under load in windows. For example, 1.425v in bios = 1.40-1.41v idle vcore in AI Booster in windows and under load that droops to around 1.376-1.384v.


    Dual Stressprime 2004 'Orthos' dual core testing:


    Note:
    1. vdimm of 2.1v in bios shows up as 2.15v in AI Booster.

    ------------------------------------------------------
    Stock 2400mhz at 1.242v vcore (AUTO):

    vCore = AUTO
    fsb = AUTO
    vdimm = 2.1v
    MCH = AUTO
    ICH = AUTO

    Idle:
    AI Booster = 20C
    Coretemp = 29-30C

    Load:
    AI Booster = 29C
    Coretemp = 37-39C

    ------------------------------------------------------
    3207mhz at 1.242v vcore (AUTO):

    vCore = AUTO
    fsb = AUTO
    vdimm = 2.1v
    MCH = AUTO
    ICH = AUTO

    Idle:
    AI Booster = 19C
    Coretemp = 28-29C

    Load:
    AI Booster = 31C
    Coretemp = 41C

    ------------------------------------------------------
    3558mhz at 1.38v vcore idle 1.35-1.36v load:

    vCore = 1.4v
    fsb = 1.3v
    vdimm = 2.1v
    MCH = 1.55v
    ICH = AUTO

    Idle:
    AI Booster = 21C
    Coretemp = 30-31C

    Load:
    AI Booster = bugged display
    Coretemp = 48=50C

    ------------------------------------------------------
    Seems to be about the same as on my Intel D975XBX when @3600mhz at 1.376-1.384v vcore load (Badaxe needed 1.371v vcore) but with P5W DH needed to raise MCH volts from 1.55v to 1.65v P5W DH consistently needs around 0.05v more vcore under load than what i needed on Intel D975XBX Badaxe heh.

    vCore = 1.425v
    fsb = 1.3
    vdimm = 2.1v
    MCH = 1.65
    ICH = AUTO



    Super Pi @9x400fsb = 3600Mhz 1:1 4-4-4-12 at 2.1v
    32M Single = 14min 21.421s
    32M Dual = 16min 12.000s / 16min 13.437s

    Isolated memory clock tests:


    Now that I've found a nice stable reference clock to work with (3600mhz at 1.376v), it's time to fine a nice stable memory clock to work with using async upclock dividers. I used memtest86+ v1.65 and in windows Systool dual 32M PI (cpu test) runs to do some fairly quick tests. I've found if you can pass Systool dual 32M PI (cpu test) you can fairly easily pass Super Pi 32M single and dual instance tests

    Memtest86+ v1.65:
    All tests done at 4-4-4-12 4 timings:
    • 501mhz at 2.20v = PASSED
    • 513mhz at 2.25v = PASSED
    • 513mhz at 2.30v = PASSED
    • 517mhz at 2.30v = FAILED with 2 errors on 2nd pass of Test #5
    • 520mhz at 2.30v = FAILED with 14 errors 1st pass of Test #5
    • 520mhz at 2.35v = PASSED
    • 525mhz at 2.35v = PASSED
    • 528mhz at 2.35v = FAILED with 4 errors on 4th pass and 2 errors on 6th pass of Test #5
    • 533mhz at 2.35v = FAILED with 558 errors on 1st pass of Test #5
    • 534mhz at 2.40v = PASSED


    Super Pi v1.5 - single and dual tests:
    ----------------------------------------------------------------------------
    I set 800 (2:3) upclock divider to test my 2x1GB Gskill PC6400PHU2 HZ Micron D9s @4-4-4-12 4 timings. I set bios to:

    fsb = 334fsb
    vcore = 1.35v
    vdimm = 2.20v (AI Booster reports 2.3v)
    fsb = 1.3v
    mch = 1.65
    ich = AUTO

    334fsb with 2:3 upclock had the memory running at 501mhz 4-4-4-12 at 2.2v. It failed Systool dual 32M PI (cpu test) near the end. So i dropped fsb from 334fsb to 333fsb via AI Booster app so that memory was running at 500mhz 4-4-4-12 at 2.2v. At 500mhz 4-4-4-12 it passed Systool dual 32M PI test fine. So ran single and dual Super Pi v1.5 32M tests with the following results @9x333fsb = 3001Mhz:

    Super Pi @9x333fsb = 3001Mhz 2:3 500mhz 4-4-4-12 at 2.2v
    32M Single = 16min 21.859s
    32M Dual = 17min 42.062s / 17min 39.641s

    ----------------------------------------------------------------------------
    Now from quick memtests and Systool dual 32M PI (cpu tests) with 2.3v vdimm in bios, memory found it's stable mark at 513mhz 4-4-4-12 at 2.3v.

    vcore = 1.35v
    vdimm = 2.30v (AI Booster reports 0.00v heh)
    fsb = 1.3v
    mch = 1.65
    ich = AUTO

    Super Pi @9x342fsb = 3082Mhz 2:3 513mhz 4-4-4-12 at 2.3v
    32M Single = 15min 55.500s
    32M Dual = 17min 14.547s / 17min 12.328s

    ----------------------------------------------------------------------------
    Bump memory voltage to 2.35v vdimm in bios, and managed to get memory to 525mhz 4-4-4-12 at 2.35v.

    vcore = 1.35v
    vdimm = 2.35v (AI Booster reports 6.54v LOL buggy heh)
    fsb = 1.3v
    mch = 1.65
    ich = AUTO

    Super Pi @9x350fsb = 3154Mhz 2:3 525mhz 4-4-4-12 at 2.35v
    32M Single = 15min 30.609s
    32M Dual = 16min 51.375s / 16min 48.594s

    ----------------------------------------------------------------------------
    Bump memory voltage to 2.4v vdimm in bios, and managed to get memory to 533mhz 4-4-4-12 at 2.4v. systool dual 32M PI (cpu test) failed near end of run at 534mhz 4-4-4-12 at 2.4v, so using clockgen bumped it down to 533mhz 4-4-4-12 at 2.4v which passed fine.

    vcore = 1.35v
    vdimm = 2.4v (AI Booster reports 0.01v)
    fsb = 1.3v
    mch = 1.65
    ich = AUTO

    Super Pi @9x355fsb = 3200Mhz 2:3 533mhz 4-4-4-12 at 2.4v
    32M Single = 15min 20.453s
    32M Dual = 16min 36.657s / 16min 33.500s

    So looks like for Super Pi v1.50 32M at least I've managed to get 2x1GB Gskill PC6400PHU2 2GBHZ Micron D9GMH to 533mhz 4-4-4-12 at 2.4v.
