Intel Core 2 Duo E6300 + Gigabyte GA-965G-DS3 OC problem

post #1 of 18
Thread Starter 
Hi all, I am new to overclocking and have come across some troubles. I have read through many posts about overclocking and have been trying the past two days before i decided to ask you all for help.

As the title says, i am currently using a
Intel E6300 running at 1.86Ghz (7x266.7) and Gigabyte GA-965G-DS3(rev 1.) Mobo with latest bios F10m

I am able to get into the bios and have been able to change the FSB to 400(FSB:DRAM 1:1), switch the ram multiplier to 2 (800mhz), PCIE frequency to 100Mhz.

in addition i turn off EIST and C1E.

However, when i save and exit these settings, the computer would reboot twice, and reset all the overclock settings i have done.

From my readings from other forums and posts, it seems that i would be able to run this overclock easily at stock voltages and i even manually set it at 1.4V to ensure that it wasnt the problem.

I have done all sorts of remedies I found online such as reflashing from Qflash and then clearing the CMOS, however, I cant get past the double boot that resets the settings.

I have tried changing the FSB in small increments and it will work at 270, but would not go past that with the same double booting results.

Can anyone help me with this problem? Please ask me for more information if i am missing something.

Can you post up your other BIOS settings (use the MIT enclosed) and complete your rig builder, so we can see the other gear you have.

Thanks again. As i said previously, i cannot find those values. i navigated through my bios to the best of my ability in search for anything similar to those titles. searching briefly online states that i may not have those available for me to change.

here is a screenshot of my bios.

Try enabling your CPU host frequency. This will allow you to increase your FSB.

You have a ton of room to move with your Vcore.

Id suggest as a start, increase your FSB to the next notch and leave your Vcore as is, then boot.

If it boots, repeat increasing your FSB until unable to boot.

Now increase your Vcore by one notch and repeat increasing your FSB.

Once you have hit the OC you want, save bios and test for stability with Prime.

If it continues to fail to boot, move your FSB down to the last setting and test for stability.

We can fine tune from there. thumb.gif

Thanks for your help and quick reply.

This is what i have done previously.

I am unable ot go past 270 for FSB. at stock vcore
i tried 275 @ 1.4V and it will still just double reboot itself.

Are you going straight to 1.4v or are you increasing it a step at a time?

Have you enabled your CPU host clock control yet?

Thanks. as you said i did went straight to 1.4v.

With your method of slowly increasing voltages i was able to get the fsb to 330 and unable to go any further as i couldnt find the proper setting. In addition, while increasing the FSB, i wasnt too sure what to set my DRAM multiplier to.

I was able to boot past the gigabyte screen without double reboot to reset my settings however, unable to boot into windows. The reason being that i could not detect any of my hard drives. I went into bios and tried to detect my hard drives but was still unable to find a way past it.
Now i have reset it back to default settings and am able to boot again.

I am not sure if overclocking will lead to issues such as the one i stated above.

With regard to you DRAM multipler, ideally 1:1 should be the aim but sometimes, its just not going to happen with certain setting combinations - dont sweat that at the moment.

Id suggest you go to your last bootable OC (fsb 330) and test for stability with Prime

I have no other suggestion to assist pass this, sorry frown.gif

Hopefully, someone else my be able to help from here...
