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

[Dakkahun]

Hmm. Did you try higher FSB speeds?

The board should be able to support them. Also, relax the timings as much as possible on your memory.

[danielniel]

yes now 425*9 vcore 1.38 fsbv +0.1 MCH v +0.175 ddr 1:1 5 5 5 15 @ v2.3 same problems

I´m thinking on changing board to a ga ep45 ud3p

[Dakkahun]

Well, I overclocked my E6750 to 3.6 GHz on X38-DQ6, with the settings provided by http://www.jzelectronic.de/jz2/index.php on the second page, "Overclocking Tipps mit Gigabyte™ X38 Boards und OCI 2GB HQ Speichermodulen"

[Fakum]

I'll keep this short. I am trying to find the setting in the bios to disable HyperThreading. Nothing that fits that description. Hyperthreading is not the setting " CPU Multi Threading " is it ?? Thanks

Thanks for the heads up.

Is the update to the AHCI version the only thing that has been changed from BIOS F9f or is there something else?

Thanks.

"new" beta bios F9J

[-Acid-]

after two hard years my board died,

its locked in the reboot loop of death
I tryed for 3 days to get it to post but to no avail

going to unsolder the main bios and solder the backup bios in its place to see if i can get it to boot

I was running bios 9h

or you might try this ? I UNBRICKED IT!! tht was from an x48T, but I did the same with a p45 extreme, after a bad flash, the x38 should be the same.

"new" beta bios F9J

some information about F9J? or only cpu microcode update?

[Sambe]

Hi all, i am a noob with this processor(QX9650 and GA-X38-DS5 bios 7d). i want to oc it to 4g or more if possible but i can not get it stable, now it is 3.8(400x9.5) with 1.375 vcore in bios but when i run prime95 i get errors of expected 0,0004 get 0,004999 .
Also have 8 gb of adata vitesta extreme 1066 5 5 5 18 @ 1066 v 2.2 (memory specifications uses 2.1-2.3)
Temps may not be a problem since as i am watercooled

I had same problen(Q9550) 8x449@1.35v is 8h OCCC stable but 8x450 not boot . I have tried raise MCH voltages etc. Mem running 890. i using newest bios version.

I've been having issues with the Lan controller on this board. Sometimes, the OS would lock after start or a long session download, and following reboot, the controller would disappear from both Device Manager in Windows, and Integrated Devices page in BIOS. Only solution I found was to load the fail-safe defaults in BIOS, completely stop the system, unplug the PSU, wait a few minutes, then boot, enter BIOS, set custom settings. After this, the controller is again present.

I am using BIOS F9b and normally, I use the second controller.

Onboard H/W 1394 [Disabled]
Onboard H/W LAN1 [Disabled]
Onboard H/W LAN2 [Disabled] line is missing when I have the problem
> SMART LAN1 [Press Enter]
> SMART LAN2 [Press Enter] line is missing when I have the problem

Tried the Gigabyte Global Technical Service, but they just stated the obvious and said to contact a supplier, for further testing. I'll try updating the drivers, and then the BIOS to the last version and see how it behaves.

[Salty]

Dakkahun, that prob is in my x48-DQ6 too. Have read of others with this as well. Flaky network adapter disappears and reappears for no obvious reason. Once, tried installing old network card but no drivers found for vista, rebooted and onboard network was back anyway. Suspect only permanent cure is a separate network card.

sadly the board looks dead

i had already unsoldered the bios chip when you posted lol

still to solder on the backup one tho

too bad. luck with spare

I'm still using f8d on my x38 DQ6. I notice I am really FSB limited. Also I can't find the setting for Speed Step in my BIOS. Even with ctrl-F1 I only have C1e and Thermal monitoring. And can not get CPU-z to recognize my q9550 as running at 8.5 even with Prime runnning all 4 cores for an hour.

Should I try the new F9J? I have 2x2G Corsair Dominator 1066. It will not even run at spec on some straps. I can get the CPU to pass all Prime running at 3.77 at 2.25v with the ram waay underclocked. I can run the RAM at stock 333 strap with the CPU running stock, but no matter what voltage I run through both I can't even get 3.77 stable with RAM at stock - 5-5-5-15, let alone pushing the CPU to 4.0.

I tried adding .1 to PCIE, .15 to FSB, any thing to MCH and computer won't boot. I even set GTLref to +3%.

You think a flash to new BIOS will help - or just time to upgrade to http://www.newegg.com/Product/Produc...358-_-Product?

PS water cooled system. CPU primed never hits 50C.

I used to run 8x400=3200 stable and perfect all day. Today my PC wouldn't post randomly. I take out the CMOS battery and it reset my mobo settings. I tried to set everything back to the way I had them. I'm 99% sure I got them exactly the same. Now, I can overclock at all. As soon as I even enable "CPU Host Clock Control" and then save/restart, my system reboots/crashes and goes to default settings. It posts and then when it's doing the "memory test" when the PC starts up, it crashes and reboots. The system works fine and is stable if I leave everything on auto and don't overclock. I want my 3.2 ghz back and not 2.4...

What could be causing this? I've been googling for hours with no result. My default ram timings are 5-5-5-15. I've tried putting it all on auto. I've tried putting it to 5-5-5-15, 5-5-5-18, and 6-6-6-18 manually and nothing works.

[tj007s13]

I ran memtest and I didn't get any errors, I think my ram is fine.

I did discover something, it seems if I unplug all my USB devices besides my mouse and keyboard it passes the memory test and boots fine at my set overclock. I have a USB Headset, several USB external hard drives, etc...

I've had USB things plugged in and overclocked fine for almost 2 years now. Should I just try a different firmware version? What firmware version do you suggest? I have tried the latest beta BIOS (F9J) and I am on F5H right now with no luck.

[Dakkahun]

The fact that unplugging some USB devices allows you to overclock suggests that it's a power issue, that the MB cannot supply the required power for the overclock with these extra consumers. Consider that after 2 years of overclock, the MB components are now aged, and may not perform to spec.

[tj007s13]

What could I do to fix this issue without buying any new hardware? Give certain parts or settings in the BIOS more voltage?

[Dakkahun]

Do you have access to a more powerful PSU for some tests?

[papatsonis]

eventhough 775 socket systems, seem a bit "Retro" (especially in this forum :P), i made this simple excel for checking allowed tRD , based on Anandtech's article

edit: put back RAM Divider selection "style".

[papatsonis]

i gave up on using this "usability factor" cause i found on some "difficult" PLs, i couldnt post no matter what... so took it from start and altered a bit.. the article's constants (till 465mhz), which gave me "realistic" results of POST or NO POST when tested on X38-DQ6
