Questions bout ASUS P6X58D-E XMP profile#1

Hi there, im kinda new here, so forgive my lack of knowledge with these stuffs so im hoping you guys with experience can enlighten me with this. I have some questions with running my mobo in XMP(overclock tuner) profile .

current memory modules used are: 6GB(3x2GB) gskill F3-12800CL9T-6GBNQ(9-9-9-24).
processor: i7 950
vid card: gtx 460
current monitor: 1660x900 will changed to hdmi 1980x1200 later

1. Is there any significant improvement in performance(especially in games) in using this profile? I think the native speed was 1066 when selecting Auto.

2. When using the Auto mode in AI tweaker, it said that the ram speed was 1066MHz, and it only changed to 1600MHz when i opt for XMP. Also in windows, epu-6 engine said that it does not support the current setting..Is xmp already in OC mode cause it only said that it will optimize the cpu amnd memory?

3. Will this wear out my memory modules if used constantly?

    Welcome Newcomer!

    1 Running your {verifed XMP} DDR at 1066 vs 1600 will cost you about 3-5 FPS loss.
    2. Use XMP for this memory, and it should work correctly for your {F3-12800CL9T-6GBNQ} DDR.
    3. It is designed to run and is rated for 1600 MHz, so no it will NOT wear out, and should constantly be running at it's 1600 MHz. This is NOT an OC for your DDR, 1700 MHz+ is an OC for your DDR.

    BTW - Great MOBO!

    QVL {Memory Support List}:
    DDR3 1600
    6GB(3 x 2GB)
    Heat-Sink Package

  2. Thanks jaquith, that's reassuring coming from a veteran. Yes, its a great mobo, although it was my second choice after the ud3r which was unavailable when i assembled my cpu. :)

    Although im still able to play games at max settings using the factory default settings, maybe ill keep it at factory settings for now until i experienced some bottleneck in memory, besides my vid card is 5~6C cooler with the default settings though and less power. I just check the bios again, the 1066MHz(8-8-8-20) was the factory default settings from the mobo.

    just a followup question:
    1. How come epu-6 engine(some software for power saving included with the mobo) does not support the xmp bios settings? when the said memory module was included in the memory supported list? :(

    Then be very thankful!

    RE: {epu-6 engine} -
    Uninstall it and most every BIOS invading/modifying App, while ASUS is not the worst it is way up there in causing oddball behavior {less = more}. Any changes to BIOS need to be done - in the BIOS. {GA Utilities are so bad that 1/2 of the overall trouble is cause by them} MSI Afterburner is about the only BIOS utility I trust, and work fine on ASUS {GPU accelerator}

    Testing Utilities are another story and only "read" BIOS data:
    Testing & Benchmark Tools: Prime95, CPU-Z, CoreTemp 0.99.6, Memtest86+, & 3DMarkVantage

    1. Prime 95 as a "Stress Test"

    2. CPU-Z for Settings Summary
    link -

    3. CoreTemp 0.99.x

    4. Memtest86+ to check memory corruption
    link -

    5. 3DMark for Benchmarks
    link -
  4. Nice link, lucky. I guess getting this mobo was worth the extra bucks. :)

    Regarding the epu-6 engine, yes, im planning on removing it as i dont need it anyway, currently using cpu-z and gpu-z to check my settings. I've also read bout the msi burner, best oc software for the gpu's. Btw, will it work for vid cards from other companies like palit?

    Thanks fro the list! Only used cpu-z so far. Im gonna try the others right now. :) Another newbie question, what does stress test do and what will be the results?
  5. Pretend {MSI} is missing - "Afterburner" will work any nVidia or ATI {AMD} GPU {it cannot read the sticker on the side}.

    A Stress test is primarily to determine the overall stability of your system {MOBO, CPU, RAM*}. Example: Prime95 places a Full Load on the CPU: all Cores + Hyperthead (if appl), and in doing so if the system becomes either unstable or unstable via overheating the test is considered a failure. Stock settings should never cause a failure, and if does then either you have installed components improperly or the components are "bad/faulted." Generally, Prime95 is use in conjunction with CPUz/CoreTemp to monitor & test OC. Pass - is considered to run Prime95 for at least 12~24 hours.

    {*} OC of RAM when CPU is under full load - can aide to instability; Memtest86+ is used to diagnose errors in RAM.
  6. I see, then i'll use it for OC'ing my gpu someday.

    Tried out the stress test for about a 5min using the factory default settings. The temp went up as high as 94C for the first core, with 98C as the max. Is that considered as a failure?

    I guess i need to add other cooling device for my cpu case for the stress test but i dont think with just gaming, i can reach that full load though.

    Yeah - BIG Failure! That's not good! Did you apply Thermal Paste on your CPU, and is the CPU fan running?

    All stock should be ~ 35C normal running, stress 40+ - 50C± maybe 60C MAX @ all sock. Don't let it get above 80C for very long and STOP @ 90C.
  8. I just used the stock cooler and the paste with it. Should i apply more?

    At boot up, the temp is already at 40~45C, and with game it rises to about 55C. Btw, may case is and i only added 1 140cm fan at the top, which makes it a total of 4fans, 1 intake (front) and 3 going out.
  9. First, pull the side panel of the case off and run tests. You want only a slight negative pressure; CFM Exhaust > CFM Intake + good airflow; the CM 690 II is a great case.

    Next, I would suggest to remove the CPU Heatsink and remove the old thermal paste using a paper towel and isopropyl alcohol with cotton swab. Reapply fresh thermal paste.

    See video -
  10. hi jaquith, thanks again for the suggestions, been out for a while, busy with my job.

    I tried out what u suggested, while using the default heatsink and fan for the processor, the temp still went up to around 80C+.

    bought a cm v6gt cooler last week and installed it last night, this time the temp went down to around 65C, 70C at max when running prim95. its quite an improvement, but based on the benchmarks, its quite high while using the cooler.

    is there something wrong with my processor? Also i noticed while using the default bios setting, CPU-z and core temp sees the frequency at around 3.22MHz when its default clock speed is 3.067MHz. This might have caused the *additional heat*.
  11. i believe this is for a different thread already. thanks a lot for the help sir jaquith.
