    Default E8300 + GA-EX38-DS4 OCing

    Hi all. Got a new E8300 installed to replace my grossly-problematic Q9450. This was gonna tide me over until I saved for an X58 system, but when I heard of LGA1156's arrival later this year, I've decided to wait.
    Anyways...

    Here is my BIOS. Currently, the E8300 is running at stock everything (bios optimized options). What should I change to get the E8300 to be 3.4Ghz (1:1 with ram) or higher?
    (Note: some options may have ?? next to them, because I forgot what they are currently - I was in a hurry to see how E8300 benchmarked)

    Advanced Bios Features
    HDD Smart: Disabled ??
    Limit CPUID to 3: Disabled ??
    No Execute Mem Protect: Enabled ??
    C1E: Enabled
    TM2: Enabled
    EIST: Enabled
    Virtualization Tech: Enabled
    Full LOGO: Disabled
    Init Display: PEG

    CPU Smart Fan Control: Enabled

    M.I.T.
    RGB: Auto
    CPU Clock Ratio: 8x
    Fine Ratio: +0.5
    CPU Freq: 2.83ghz (333x8.5)
    CPU Host Frequency: 333mhz
    PCI-E Freq: 100
    CIA2: Disabled
    Performance Enhancer: Turbo
    Sys Mem Multi: Auto (shows 5:6 in CPU-Z)
    Mem Freq: 800mhz (because of the 5:6 strapping)
    DRAM Timings
    Primary Timings: 5 - 5 - 5 - 12
    Sub Timings: I'm unsure what these are at the moment
    ACT to ACT Delay: ??
    Rank Write to Read Delay: ??
    Write to Precharge Delay: ??
    Refresh to ACT Delay: 42
    Read to Precharge Delay: ??
    Static tRead Value: 7
    Static tRead Phase Adjust: Auto/0
    Command Rate: Auto (probably auto'd to 2T)

    Voltages: All currently at Normal, LLC at Auto
    DDR2 OV Control
    PCI-E OV Control
    FSB OV Control
    (g)MCH OV Control
    CPU Vcore

    So what should I change to test for 3.4Ghz stable, and possibly above that? I hear dual-cores are better at OCing than quad-cores.

    Please give me a link to your ram and tell me how much of it you have installed.

    Then I can best advise you. C1E and EIST Should be disabled for sure

    Problems with Q9450? What issues did you have? Wow, I have never heard of E8300

    Here you go: Patriot Memory - Products

    C1E and EIST off. Gotcha!

    Yes, the Q9450 was the source of my OCing woes before. Not to mention that it was also the source of my BSODs and RSODs too.

    The E8300 is a dual-core CPU. I suppose you could say it's the dual-core counterpart to the Q9550 (minus 2 cores, they seem to be the same). Haven't had problems with it, and hopefully I never will.

    *sigh* Sorry. Got 2x2GB.

    Been upping the E8300 by 10mhz. Currently at 3Ghz (353x8.5). Temps, for once, are decent (given Australia's summer weather): low/mid 50s when under load. Low/mid 40s otherwise.

    Well for 2x2 you should set your voltages as I noted above. Also, you can use 2.40B multi for 850Mhz for the above speed if you like. Those are 444-12 @ 800 sticks, so at 555 timings you can easily do 900-1000 once you set your voltages

    Good luck, looking good so far. I have three pages of posts to get to so I will catch up with ya later

    Thanks man.

    Speaking of the RAM, a review I read did major testing of my chips and others. The Patriots, shockingly, could do DDR2-1200mhz with 7-7-7-11, and DDR2-800mhz with 4-4-4-4, both at 2.2v. But whether my particular pair can do this is not known...yet.

    You think my E8300 would be okay if I upped the 10mhz boost to say 20Mhz?

    Ya, with high/loose timings most all will do 1200 with 2.15-2.2.

    Ya, I think your CPU can do 4Ghz likely. I use a E3110 (Same as E8400) and mine will do 4.4+, I see tons of E8400's doing 4.5+ all day long

    So you can for sure go higher, just keep your ram loose until you are done with your CPU. And you may want to use the D strap after 400 FSB

    The very advice of a mate I speak to on WLM. Overclock one component at a time. That's why the memory timings are still all set to Auto. Once I'm happy with the E8300's max potential overclock, I'll move onto the memory, and then onto my HD3870X2 (via Rivatuner).

    I'm using the 2.00D strap now mate. It's underclocking the memory too, which is a good thing I guess, because I know it won't be the memory that stuffs up. If I try for 1200mhz and 7-7-7-11, I'll have to change though. Going 1:1 for that memory speed would mean a 600mhz FSB. Sounds risky to me!

    Currently at posting time, the E8300 is at 3.17Ghz (373x8.5) on stock Vcore (well, "Normal" Vcore setting w/LLC still on Auto).

    Just quickly, lsdmeasap, what would be more performing: 1200mhz w/7-7-7-11, or 800mhz w/4-4-4-4?

    Update
    Got the E8300 to 3.4ghz on stock Vcore (memory is still loose). Tested with Orthos, but one core failed in less than a minute (weird). Went back to Bios, raised Vcore by one increment, and I also adjusted the other voltages too (should have in the first place).
    Temp wise, it's pretty good today, as my area of Oz has a nice cool breeze. Last time I checked with RealTemp, the core temps were in the mid-high 30s! :D

    Update #2
    Was doing some Orthos tests but they failed kinda quick. Funnily enough, after setting the NB voltage to what lsdmeasap recommended, Orthos didn't fail and went to the 15 min mark.
    Decided to test 410mhz (3.48ghz) too. Went to benchmark Far Cry 2 but it caused a BSOD just as the benchmark was going to start. I kind of took this as a sign not to go any further (at least for the time being). I mean, I don't want another CPU going ass up! The E8300 is doing well anyways, at 3.4Ghz, and the 2x2GB memory at 800mhz and 4-4-4-12-2T.
    For reference, here is my BIOS as it is currently set...
