Official GIGABYTE X38-DQ6/X38T-DQ6 Info/BIOS Thread

[Isepick]

@Sobek: I have the T version (1.0) and had similar problems, also could not get the board prime stable at ALL on any settings....until I removed the Gigabyte Sata driver...and now it is rock solid, although I cant get the FSB over 375, think it has something to do with the NB getting hot, will let everyone know when I get all my watercooling gear in after the holidays whether or not that helps...My problems were only apparent when I had 2nd 3870 in the computer...didnt matter which board was in which slot and whether or not I had the crossfire cable attached, just having two vid cards in the slots seemed to do it. I get windows wanting to install new hardware everytime it boots, but since I am not using those 2 sata ports atm, I ignore it...I had tried removing the JMB ide controller, but that didnt work. It took me a WHILE to finally make it fail to the point where win xp refused to see the 2nd card until I started removing drivers out of the system...I also removed the EasyTune utility in all of that, since I do all my OCing in the bios anyway...But since those pcie 2.0 slots go through the NB directly I think there may be a bug either in the NB itself or just in all the fubared bioses we get from GB...anyhow thats how I solved my problem, hope it helps you and others....

interesstening that your jmicron sata controller also seems fubar, i have the same probleme here (Rev 1.1 X38T).
I had my optical drives controlled by the Jmicron but everytime i installed the drivers my system began to stutter while starting windows or shuting it down...
I removed the drivers and disabled it in bios -> rock stabel since than...

But its strange, cause on my old 965P-DS4 has the same Jmicron controller and it works without a problem...
