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

ok so i received the DDR2 bios that has working half multies based on F3

here it is

beware this is for X38-DQ6 DDR2 boards

I DO NOT TAKE RESPONSIBILITY IF YOU KILL YOUR BOARD WITH THIS BIOS >> MINE WORKS BUT IT DOESN'T MEAN YOURS WILL SO PROCEED WITH CAUTION

[freqy]

there was a catch with this half multi bios wasnt there? only for dual core? not for quad? or something?

Ok, I have been watching this thread for sometime now and have some questions.

Let me give some background on my setup.

X38-DQ6 w/F7 bios currently
E6750 with Tuniq Tower 120 for a cooler (replaced fan with higher speed)
Mushkin 4-4-3-10 2x1GB PC6400
PC Power and Cooling 750watt
MSI 8800GTS 512 (stock OC version)
TONS of case fans in a LianLi full tower.


Currently im running 450x8 using the 2.00D , which is running 1:1
Timings are 4-4-3-10

Voltages
DDR2 +0.25
PCI-E +0.05
FSB +0.20
MCH +0.10
vCore is at 1.44375


Temps (when ambient air is 71F)
idle at 27C
load at 53c MAX


Here at my questions

1. What are the dividers and straps? I dont understand the A, B, C and D things. I just picked one that gave me 1:1 ratio (i read it was suggested to run core2 at this ratio)

1-(Part B) What really is the best ratio for the core2s? what gives the best performance?

2.how are my voltages looking? am I too low or too high on anything?

3. I plan to get to 4.0ghz, think ill make it on air if i lap the cpu? (HSF is already lapped)

4. Should I get a fan on the northbridge heatsink?

5. should I worry about vDroop? some people say its ok, others say its bad, im confused


Ok, that should be good for now. I just want to thank everyone that has posted so far. I have learned alot about this board thanks to all of you! keep up the great work!

After many many efforts and trial and error combinations , having in hand the excellent X48 Rampage Formula Anandtech's REVIEW i found a 24/7 stable setting with minimal(or what i thought minimal...) Voltages for my parts , 400fsb 6:5 divider(4x1gb 960mhz ram 4-4-4-12), tRD=6, with all subtimings very aggresive.Had done many tryouts to tighten the tRD increasing MCH voltage, in this , or other combinations , with no luck , so i had left it on "Normal"... The problem was that a cheap thermistor was showing 55-57 Celsius , and i couldnt even touch my finger for more than 3-4 seconds..on X38. Strange cause someone in this/or other x38 based mobo thread mentioned he got mid 40's C!!! .A while ago in another thread here ,pardon my "amnesia" again , i saw an asus motherboard that with auto setting in some voltages the bios was setting much more Voltage than nominal defined.. .Guess what.. DQ6 (at least with F8c bios..) at "Normal" vMCH in fact sets +0.250volt !!!! , when leave all voltages to AUTO ,it defaults to 1.25volt but when set to "Normal" i measured about 1.485volt!!!! (+0.025 volt measures about 1.268volt) .Finally it seems for the above settings i need about 1.36vMCH :/ for Extreme Bios setting , but eventually ill be happy with Turbo and +0.025vmch only (it still gets too warm :/) .Does anyone know where to measure CPU VTT (fsb voltage?) and vPCI-E on the motherboard? cause in another forum i found a reference for another gigabyte intel mobo that overvolts also FSB voltage and vPCI-E and its highly possible that does the same overvolt here at "normal" setting

p.s.> afterwards i saw in bios a message "voltage will be raised when overclocking " or smthng like that, but get me nuts this "big brother" behaviour of DQ6

[dinos22]

ALL/MOST good motherboards when set to auto will most likely overvolt

you are overclocking FFS
if you don't have control over it you should stick to stock otherwise use auto for initial testing and then determine values and in particular volts for 24/7 systems

i have mine set on 24/7 machine of course

Has anyone already tried tihis bios?How does it work?

What, things are different from original F3, other than half multis ?
I like F8C

[*GiZmO*]

It would be great,if the new F3 would be like the old one (high FSB,speed...)+ the corrections in the F8c!

[road-runner]

I got a X38 DS4 today and under the sticker it says X48 DQ6, I wonder can this board be flash to a X48 DQ6 latter on?

No, because it has different PWM, maybe Dual Triple Phase (as I see in the picture), not a Quad Triple Phase as a real DQ6.

So the power circuit of the CPU is different, that means that the bios is not changable with DQ6's.

Hey dinos - how is this bios going on your board? Similar to the original F3 for overclocking etc? I could really use the half multis for my benching

i've only tried max clocks and was a bit tricky getting the CPU to do SPI at 5.3GHz and 5.2GHz

i have to stick some LN2 on the chip to eliminate cooling issues and will report back but it seems fine
