Thread: E8400 Safe Voltage Help




  1. #1

    Default E8400 Safe Voltage Help

    (See Specs in my Sig.:)

    I'm up to 3.95GHz with vCore @1.35000V. (Everything below is in reference to both of those two values.)

    Is it safe to set vCore higher than 1.35625V and 1.36250V?

    Or are those two values the 'End of the road'?lol

    I want to reach at least 4.0GHz and I'm 'running out of track'.lol (sry)

    Or do people consider the following Voltages also safe to try:

    1.36875V
    1.37500V
    1.38125V
    1.38750V
    1.39375V
    1.40000V

    I can finish "Super PI0" no problem (1m,2m, and 4m).

    My "CPU VCORE" in "HWMonitor" after running "Super PI0" reads:
    1.31 Value
    1.30 Min.
    1.31 Max.
    (Seems cool.)

    And my "Temperatures" in "HWMonitor" after running "Super PI0" read:
    Core #0... 37 Value... 35 min... 54 Max...
    Core #1... 30 Value... 27 min... 48 Max...
    (Seems cool- no pun intended.)

    But I can't complete the 3rd simulation in 3DMark'05. (It CTD's towards the very end where the Dragon opens its mouth to swallow you whole.lol)

    I bet 3DMark'05, and my games will work @1.35625V and @1.36250V. I'm just hoping to hear that it's safe to go higher. :) *fingers crossed*

    Thanks!

    Default Re: E8400 Safe Voltage Help

    The Intel Spec Finder for your E8400 shows: VID Voltage Range: 0.85V - 1.3625V

    Older C2D chips have a max rated voltage = 1.50 volts and it's recommended to keep their voltage below 1.40 volts for normal operation.

    When you factor in vdrop and vdroop, it might still be safe to set the cpu vcore as high as 1.40 volts if needed.

    Your temps look good. Running higher than specified voltage will shorten your cpu's life. It's recommended to run the lowest voltage that provides system stability.

    FSB DeOverVoltage Control <-- is this a typo?
    Have you included all the bios voltage settings in your post?

    Don't get too hung up on the "magical" 4.0 GHz setting.

    See what other E8400 overclocks are running by using the forum SEARCH feature and search on:
    E8400+overclock

    Running close to 4.0 GHz might be as good as it gets.
    What is your highest stable cpu speed?

    Really nice post with your template. It's easy to read, includes your specs, and doesn't have the normal comments clutter. We should make you the bios template editor for all posts.

    There are some memory timing tweaks that will improve system performance, once you have a fully stable system.

    Please include a link to your ram's specs.

    The "FSB DeOverVoltage Control" is correct ProfJim. I'm guessing from a picture I took of my Advanced BIOS screen that its still set at "Normal".

    (I can only see it in the Advanced Menu after hitting Ctrl+F1 at the main BIOS screen.)

    What is it? It won't hurt me will it? (jk lol)

    hehe. Your too funny ProfJim!

    Did I thank u for first post?

    Well, thanks for it, and your 2nd one too ProfJim!

    (Warning ProfJim! All below is just clutter! sry)

    Because FSB DeOverVoltage Control @+0.1 is set normal I'm confident it will help at +0.1. (*fingers-crossed*) But more importantly, it increases the number of permutations I have to go with! Or to be more accurate, it will help enormously by replacing many failed ones!(YES!)

    And running out of voltages and or permutations, is exactly what I was originally afraid of and why I made this thread. (Thanks again ProfJim!)

    Telling me to reduce the MCH from +0.3 to+0.2 is just awesome news, too!

    Because +0.2 has always helped enormously at lower vCore Voltages (and MCH @+0.2 is a "must-have" at higher vCore values), it makes sense now that MCH @+0.3 at higher vCore voltages hasn't helped.

    MCH @+0.3 had been sort of a last resort. Or something just to do in order to cover all possibilities. But now I know its unnecessary. (right?)

    And I can replace "
    MCH @+0.3" with "FSB DeOverVoltage Control @+0.1", in my list of combinations to try for each vCore Value.(?)

    So, the higher the vCore, maybe the more
    MCH @+0.3 contributes to reduced stability?

    Also, the plan I came up with yesterday; based on ur 1st post ProfJim, sounds better now when I thrown in, "FSB DeOverVoltage Control @+0.1" and "MCH @+0.2 and I removeMCH @+0.3).

    The Plan
    basically consists of covering all possibilities with vCore up to, but no higher, than 1.35625V or 1.36250V. And then after not worrying about the "'magical' 4.0 GHz setting"; because ProfJim suggests seeking out stability over speed, I can move on to tweaking the memory timings just down the road; in order to improve performance.

    Thanks again for all the help and advice ProfJim and any additional!

    PS
    As far as the Memory Link to add to my sig like u said in ur 1st post, all I can find is:
    http://www.corsair.com/products/go.a...X4096-8500C5DF

    I searched and search and cant find anything else. Is it cool? All it shows is that 5-5-5-15 and 2.1v is suggested by manufacturer.

    And the kit includes, an Airflow Fan, to weigh down paper on your desk. ;) (sry, i had to sneak that in.)

    Last but not least, I've got MemSet installed if needed too.

    Default Re: E8400 Safe Voltage Help

    It worked ProfJim!

    -FSB DeOverVoltage Control @+0.1V
    -
    MCH @+0.2
    -CPU @3,950MHz!!!!
    -RAM at 1054Mhz 5-5-5-15
    -CoreVoltage+1.35000
    -FSB Voltage +1
    -FSBDeOvervoltage +1

    (w00t!!!
    )

    And my "Temperatures" in "HWMonitor" after running "Super PI0" and 3DMark'05 read:
    Core #0... 37 Value... 36 min... 54 Max...
    Core #1... 30 Value... 29 min... 46 Max...

    25,610 3DMark'05 Score! (Highest score ever of course.)

    Now I'll attempt to crash with Crysis on Very High 2XAA, 1920X1200.muahaha

    Edit:

    After 30 Minuets of playing "Solitaire"... oops I'm mean "CRYSIS" LOL.... CPU @3,950MHz is stable as a rock. w00t!

    And Max temps remained same as above.

    Edit:

    I can restart and BIOS remembers my "3.95GHz" Profile. :D

    But if shutdown, then restart, BIOS forgets the settings. :(

    (Note: And if BIOS forgets a profile of mine or changes I've made to it, I always Load Optimal, Apply Optimal, Exit BIOS, then go back to BIOS before attempting changes.)

    Thanks!

    It sounds like your mobo's battery is failing. Check it's voltage in EasyTune or other programs that monitor system temps, such as SpeedFan, Everest, HWmonitor, etc.

    Check out this post for saving bios settings using the bios PROFILES features.

    Awesome!

    I'll definitely do both!

    I hope ur right about the Battery! It would be too too nice and I have a couple new batteries already. (*Bee Prepared!*)

    I needed the Profile Link last week. I didn't know it existed.

    Thanks!
    _____________________________________________
    Edit:

    The New Battery Fixed IT profJim!!!!
    The Victory Link!!!

    Your brilliant ProfJim!
    (*I'll have whatever he ordered*)

    TYTYTY!!!

    I've shut down completely for over 20 secs, then restarted, and shutdown for over a minuet, then restarted; and BIOS remembered my 3.95GHz Profile each time.

    Now, I'll read the Profiles link that you were so nice to suggest just above. And study it! (this post)
