    Default Re: 1st time poster would like to overclock my E8600 while waiting for Sandybridge!!!

    so, quick question. If my memory settings are too high, will the bios throttle them back before i even get into memtest? I had tried a setting at 440fsb w/no problem, but at 450fsb w/performance level 8 w/2.00D when i went into memtest 2.15b the memory settings were back at 333mhz.

    So,when i adjusted to perf level 9, they worked successfully. I guess my question is as i increase my memory speeds, which settings are most likely the ones to adjust first?

    Did the system perform dual or multi boot after you set 450MHz FSB?
    This is a sign that the settings didn't take. To be sure always return to MIT after changing settings to make sure there is no problem. If there is a problem you will get a warning, and the BIOS will chose some good settings that are known to work.

    The bios will fall back to default (safe) settings when it can't apply the settings.
    Incorrect settings include improper voltages, memory/cpu settings and/or settings that are too aggressive.
    As stated above, going into the MIT bios section after you've rebooted will show if your settings are "acceptable", but not necessarily stable. A red warning box will appear in the MIT section if your mobo barfed on your settings. ;)

    Chike,

    from what I remember it only rebooted that one time and then went straight into memtest as i had set it to boot to cd first. However, when I got into the program, i noticed that memory speed was not at 450, but 333 if i remember correctly. I then changed the performance level of 4-4-4-12 perf 8 to perf 9 and everything was ok.

    profJim,
    per my second question, "I guess my question is as i increase my memory speeds, which settings are most likely the ones to adjust first?" Do u have any recommendations on which settings to look at first? Obviously performance level is a big one, but do i look to keep the 4-4-4-12 settings as long as possible or progressively change them in a certain order?

    General guidelines for your setup:
    • 4-4-4-12 memory timings are generally ok up to 875 - 925MHz with 4GB of memory and probably less with 8GB of memory
    • tRD = 8 is generally OK when using the B-memory strap from about 420 - 470MHz
    • tRD = 9 is generally required when using the D-memory strap from about 420 - 500MHz
    • some find that it's easier to get stability when using the D-memory strap with FSB = 400MHz or higher
    **edit** Sometimes the tweaked memory timings will work, even after the reboot has to do the boot loop dance, but this is the exception, not the rule.

    profJim,

    thanks for the more specific info. I will continue to try 4-4-4-12 up to about 465mhz w/2.00D timing and tRD=9 (perf lvl, right?) --still stay about about 2.02-2.04vdimm

    Next, at some point I would begin to change memory timings closer to a 5-5-5-15 or similar w/2.00D and tRD=9 if i wanted to go higher?

    Finally, I know we talked about this before, but for the game I am currently playing (WOW--unfortunately--complete time sink) CPU speed is really the ultimate focus, not memory. So, does it make sense to go to more relaxed memory timings and lowering the multiplier? I would think that some quality testing around 440-450 and then some voltage changes for the CPU--up to 1.3625 as u stated previously, would be my best best for running somewhere between 4.2-4.5Ghz, does that sound correct?

    Yes tRD = PL (performance level), aka Static tRead Value.
    Some have reported that gaming performance is virtually the same when using:
    - 800MHz with 4-4-4-12 timings
    - 1066MHz with 5-5-5-15 timings
    where the difference will only be 1 - 2 fps

    Using an intermediate memory speed, you'll need to find the optimal timings.
    With my system's memory speed = 984MHz, my optimal memory timings are 5-5-4-12. YMMV

    You will probably find that maximizing FSB (CPU Host Frequency) will work best.
    My best guesstimate is that your optimal performance will be with:
    - FSB = 500MHz
    - CPU multiplier = 8.5, cpu speed = 4.25GHz
    - Memory multiplier = 2.00D, tRD = 9 or 10, memory timing = 5-x-x-x

    You might find that you get similar performance with FSB in the 450 - 475MHz range with an appropriate cpu multiplier.
    Even if you you o/c higher than 4.25GHz, the improvement in game play will probably be minimal.

    I recently bought an MSI N460GTX Hawk (1GB) video card. HOLY SH*T!!!
    Many of the higher end 460 1GB cards will overclock to 900 - 920MHz or a bit higher.
    With the current holiday sale/rebate pricing, you can pick up one of these for $180 or less.
    Check out the GTX 460 reviews where they have gaming benchmark results that include scores for older cards.

    nice card!..i have heard good things about those...ive been saving up for my next system...hopefully with a mobo just like this...

    man is that thing of beautiful or what!!!

    that combined w/a geforce 570 and a decent ssd is what im shooting for.

    Guess I'll have to check out the P67 that you're drooling over.
    I did a little more overclocking with my Hawk and it was 10 minutes Kombustor stable using:
    • DX9, 1920 x 1080, AA:16XQ (Quality) CSAA
    • 935 - 1870 - 4400 (QDR) MHz (gpu - shader - memory)
    • +0.100 - +0.040 - +0.000 volts (gpu - memory - auxiliary overvolts)

    Not too shabby when I know next to nothing about video cards ;)

    BTW, stock settings for the Hawk are 780 - 1560 - 3600 (QDR) MHz
    ps: Using 950 - 1900 -4400 (QDR) settings, I only got about 8 artifacts during the 10 minute test, so close and yet so far....
    final bit of trivia: I don't normally give my hardware nicknames, but the MSI Hawk is now called Missy (get it? MSI....Missy....oh never mind)
