GA-EX38T-DQ6 boot problems after bios flash

I have an identical setup to you with the same memory, processor, and motherboard (the X48T-DQ6 is the same as the EX38T-DQ6 except the chipset is validated to run at higher clocks) and experienced similar problems at my first boot.

Of course, make sure that you first clear your CMOS by unplugging your PC then shorting the pins for 5 seconds.

After that, if you get the computer to start and display a boot screen (The Gigabyte logo) then crash, you probably have the same problem that I had. The problem is that the BIOS defaults to 1T timings for 2GB sticks of memory. Go into the BIOS configuration then into the M.I.T. (Motherboard Intelligent Tweaker) options and set the memory timings configuration to MANUAL instead of AUTO. Then go to the command rate setting and change it from AUTO to 2T. The memory is not rated to run at 1T which is the AUTO setting and this causes the computer to crash.

Also make sure that the DDR3 overvoltage is set to +0.40V. The normal setting is 1.5V while this OCZ memory needs to run at its manufacturer specified 1.9V to achieve its rated timings.

After changing those settings it should work.

Also, I have a request for you since you have the same configuration as me. I am having trouble even slightly overclocking the processor even though the configuration is stable at stock speeds. Changing the CPU Clock Host Control to even 334 MHz (1 MHz overclock) causes the computer to refuse to boot. I think that the memory may be the issue as GIGABYTE has no 2GB sticks DDR3-1333 or higher in its validated memory list for these boards. If you experience the same problem, please tell me so that I can confirm my hypothesis. I think that this may be fixed in a future BIOS update, but for now I am just running at stock speeds.

Anyway, I hope this fixes your problem. Let me know of your results.

No looks like I should not have flashed my bios in windows using that **** @bios from gigabyte. The flash is bad and the backup seems gone.

Going to send it back I think.

Well it is trying to spin the dvdplayer when I turn it on. But the problem for me is that the dvd that came with the mb has only drivers etc on it.

Or another idea, if you have a flash stick, flash your bios from it, i used it , worked great, plus i liked the idea, if i had a issue, i could put the flash stick into my other computer and get a diffrent bios on it and give it another whirl.

If the gig mobo is new enough, its gonna let you put the flash on the card, and then when you get your splash screen at boot up, you will have a f option to load it up.

Flashing the first bios shouldn't affect the backup. If it posts, the backup may not kick in automatically because it thinks the first bios is working, as it does post. There should be a button that lets you switch to backup manually. I forgot which one, but it should display on POST screen.

Powers on for a few seconds and then powers off from what ive gathered dagger.
