    Unhappy EX38-DS4 will no longer overlock!?

    I've been running a Gigabyte EX38-DS4 for a couple months now on a Q9450 OCd to 3.44Ghz. I verified my CPU was running at 3.44Ghz (with CPU-Z) several times as I was doing my stress testing. A couple days ago I fired up CPU-Z only to find my CPU was at 2.66Ghz (8x333). So I go into the BIOS and see nothing has changed, Freq is at 430x8. I change back to defaults, boot up at I see the name number 2.66Ghz in CPU-Z. I go back into BIOS, change the setting to 430x8, boot up and still 2.66GHZ. I have EIST, C1E and all that turned off. I reflashed twice and I loaded settings from my baseline 2 months ago to no avail. I also tried using another Q9450 with the same results. My BIOS version is F3 (latest). What is going on here????

    You could try reflashing the BIOS, and be sure to load optimized defaults then save and apply, reboot then come back in BIOS to make your changes again.

    Other then that, If you have already tried this then your stable overclock may not be so stable as you think and so the board reverts to defaults. Even if it WAS stable months ago, that does not mean it is nowadays. Or you could also have failing memory, I would test your ram on another board as a starting point before anything else

    What ram is it?

    Can you test something for me? Save the settings you are wanting to use that you think/know are stable as a BIOS Profile using F11 on the main page, name the profile and hit enter. Then clear the CMOS with a hard drive or optical jumper on the Clear CMOS pins with your Power supply unplugged for about 10 minutes. Then remove the jumper, plug back in your PSU and then load the BIOS, hit load optimized defaults, save and appply and reboot back into BIOS again, then hit F12 and load the profile you saved and see if it works now.

    Also, be sure you have Init First Display set to PEG2

    Hello. I tried all these steps and still get the same result. No overclock takes at all not even 334 which is only 1 Mhz higher than the default 333. The BIOS correctly saves the setting but the initial boot up display screen always shows 333x8 (And so does CPU-Z, Vista, and other tools). These tools used to report the same values from BIOS (430x8/3.44Ghz), now they don't. Is this board fried?

    You say you do for sure have C1E, EIST, TM2(optional) and C.I.A.2 disabled?

    Have you tried flashing back to a older bios, or is there only one that supports your CPU?

    Do you have external USB devices? If not, be sure Legacy USB support is disabled as well.

    What settings are you using in MIT, maybe something there is causing defaults to load on you? >>>>

    Just a template I use to ask people there settings, pay no attention to the numbers in it, replace with yours

    Hello,

    My RAM is 4GB of G.SKILL F2-6400CL4-1GBHK. The 4-4-3-5 timings supported under EPP #1. I relaxed the timing to 5-5-5-15 but same result. Yeah, my Q9450 C1 stepping requires the F3 BIOS. I ithink it can run with F2, but it's not officially supported. C1E, CIA2, and EIST are turned off. TM2 is on (but I've tried it off as well).


    What settings are you using in MIT, maybe something there is causing defaults to load on you? >>>>


    That's the problem. Defaults are *not* being loaded. Going into the BIOS shows 430x8 (the correct setting). Booting up from there however , everything shows 333x8. I noticed some slow performance when I was encoding some videos, so when I checked CPU-Z i noticed it was running at 2.66Ghz (333x8) even though BIOS still shows 430x8.


    I filled in the details below..

    Thanks.

    You may need at least +0.1 or more for 2x2 sticks, and you should manually set the refresh to act delay as well to 52-62

    Everything else looks acceptable. What PSU do you have, and are you using the 8pin CPU plug?

    Ok, i'll change those settings. I have a corsair 620W. Yes, 8 pin CPU plug being used. I have a load monitor and its showing 118W at idle.

    K, just wondering about the PSU.

    I will be back later today, good luck with testing

    I made the changes but still shows 333x8.
