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

[zsamz_]

It happens because youre using dual channel. Ill bet if you set your memory to single channel you'll not only be able to run the ram at higher speeds, but also never get the cold boot issue.

Theres a bug with this board in the way it handles dual channel and adjusts TRD. Gigabyte is working on it, and should release a working BIOS as soon as its sorted out. Until then, run your ram in dual channel below 950mhz, or in single channel at higher speeds. In most cases, you'll get the best performance with tight timings and below 950mhz anyway, so..

Most ddr8500 memory should do just fine on this board at 2.3v 950mhz 4-4-4-4 timings. Adjust up to 4-4-4-7 if unstable. Make sure TRD is 8 or above no matter what. Also, Use standard or turbo on the performance enhance setting,- extreme is unstable in most cases in dual channel mode.

Most of us are having trouble making this board run stable at ddr8500 with just optimized defaults, just because of this bug. Just reset bios and boot with a single stick so you can set TRD to 8 manually. After that youll be set...

Ive also noticed unstability when upping FSB and MCH voltages. The board seems stable at default values up to 475mhz, so no need to touch'em anyway unless your multiplier is below 8.

for 950mhz 4-4-4-8 you only need 2.1v -2.2v max and 2.2 can get you to 1040 easy i wouldnt do 2.3v 24/7 on a gigabyte board unless i needed to
i lost 6 gigs @ 2.26v
with 2.26v i did 5-4-4-9@ 1150 on the dq6

Ok here are my specs again:

The one and only Gigabyte X38 board with bios F7d now
Q6600
OCZ Platinum 2 x 2GB memory
Corsair 620W ps
Antec P182 case with 3 fans
Scythe Mugen
Leadtek 8800 GTS 640
Hauppauge HVR1300 DVB-t tv card
Creative X-Fi extreme gamer sound
1 x 74 GB Raptor
1 x 500 GB Samsung
1 x 500 GB Thoshiba external, not connected on boot
G15 keyboard
G9 mouse
G35 steering wheel, not connected on boot

I just got home and tried to boot again, loaded 9 x 400 settings.
Boot failure.
I changed the strap, which i did before without succes, to A266 and it booted without problems.

I will see what happens tomorrow when i cold boot again.

You ran 5-4-4-9@ 1150 in dual channel mode for 30 minutes in OCCT on the dq6 ?

What brand was this, and what bios ?

[freqy]

Make sure TRD is 8 or above no matter what

>hi do you mean static tread value set to 8 will everything else on advanced timing control be o.k at auto?

glad gigabyte is on the case of a more suitable dual channel bios.

peace.

Yes, thats the one. The rest is fine at auto apparently.

[ps3 is great]

I get an error message when i try to install the drivers for my bgears soundcard, they're the latest drivers for my o/s (xp). It's inserted correctly and securely and completely into a pci slot.

it says please plug in c-media oxygen hd and try again.

is this a common issue?

does anyone have any suggestions before I try the other pci slot?

onboard is disabled and no audio drivers are currently installed.

i'll appreciate any help.

memtest passed 100% f3 bios
memory was my crappy mushkin xp-8500
my ballistix 8500 are way better
but i couldnt do 1200+ i could do 1300 on my p35
i only played 3 weeks with the dq6 before i gave up on it thats over 150 hours of testing

guys
Performance Enhance : Standard
it will hurt your performance at expense of little more stability

make sure you also test Turbo mode as it really improves memory performance a lot


Static tRead Value: USE LOWEST POSSIBLE STABLE VALUE HERE

i was mostly running @ extreme but to be more stable i started running @ turbo
you right dinos anything lower than turbo is verry slow

[freqy]

Static tRead Value: USE LOWEST POSSIBLE STABLE VALUE HERE

>
coool ..huh hu yeah hmm ....(bevis impression) ...

at what value do you set static tread value? ..roughly?. does it make the memory run better? i have it at '8' at present. someone on here said dont take it any lower.

also testing my memory with turbo performance enhanced.in memtest as you sugested. seems o.k so far. at 1066 (400fsb)with pc-800 dominators..

peace

[Alcibiades]

I have tried ALL bios revisions like most ppl
I SWEAR by bios rev. F5G and F5H
No other bios rev's allow me to achieve the same high performance and stability.

I clock in at 460fsb x 8, 333 strap @ 1104Mhz 5-5-5-14 trd 7 extreme
or 460fsb x 8, 400 strap @1224Mhz 5-5-5-14 trd 7 extreme

can't reach these high settings on other bios rev's

F5H is what I use now and no cold boots

[freqy]

Static tRead Value :

yeah if i have this set at 5 it wont boot at 6 its o.k .
i'm only running 400fsb x7 1066mhz 5 5 5 6 timings

im drooooling for water cooling..

.....i would use my droool but its a bit warm.

hi zicada

how did you find out there was a dual channel problem and that gigabyte are to release a bios to fix this?

[dinos22]

Static tRead Value depends whether you are running a quad core or a dual core

it also depends what your 24/7 FSB MHz settings are as well

basically this value seems to be part of the PL(performance level) value you see in maxmem but i'm not 100% sure it's completely the same

i don't actually use a Gigabyte machine as my 24/7 system so i don't really set the same thing i am suggesting you guys

what i do on benching setups is loosen it up to 8/9 and then tighten back in windows....reason for that is that i've found a FSB boot wall on yorkfield for example while setting a lower value and it was doing my head in why i could not get the damn thing to boot past 410Mhz FSB in last set of testing for example.....after loosening it i was able to boot and bench at 450Mhz without any issues on water heh

Yes, i was wondering about these settings that are listed in memset that are not in the bios. Like the "refresh period" or "tref" in memset with a number like 3120T.

I think these are changed with "performance enhanced" setting in the bios, bcoz if you change it in the bios, memset will show different results. Memory timings seems to be the biggest issue to get this board running right.

Although i had some problems at first with this board, after a bios flash and a little tweaking i really love this board.

Guys, to use lower static tread value with high end video cards installed, back off on the sub timings particularly tRFC, tRTP, tWTR and tWR with all 4 values in bios set to 42, 5,8,5 respectively i can use static tread = 6 no probs so far

To go tighter on subtimings and/or lower static tRead you need more memory and GMCH voltage - alot more!

8x400FSB 3:4 533Mhz 4-4-4-8 on memory

[freqy]

this may seem a silly question

is it possible to get a failed over clock ( prime or memtest86) with your timings to loose?? as in 7 7 7 20 are there situations where just a little tighter will make it work?

[freqy]

hi i posted my question before i saw your post ..thanks for your reply im gonna read it through properly now

[merlin76]

Most important thing is to set tRD manually as the BIOS has bug when tRD=Auto. Although showing tRD=8 in BIOS for example it uses tRD=12 which kills performance.

Here's 400x8 1:1 tRD7:


Settings:
400x8
2.0A Turbo
4-4-4-12-3-3-6-42-3-7-Auto-2T

460x8 1:1 tRD7:


Settings:
460x8
2.0A Turbo
4-4-4-12-3-3-6-42-3-7-Auto-2T

Board voltages are set to Auto but board overvolts Vmch automatically.

If you are having issues with F7 BIOS that your SATA optical drives are not recognized correctly set "SATA Port0-3 Native Mode" to "Enabled".

[Wakuwaku]

This morning i had a good cold boot again wow!!!!! Seems i found the solution now.

[freqy]

great waku waku!! glad for you ....now y can tune away! and then get some real use out of it at last.

you certainly were pateint with it. hope it meets all your expectations and more...

[freqy]

just read on a forum

Performance Enhanced > change the value (turbo or extream) only if you have EPP RAM.

[kernkrafter]

Hey, ive tried to search for my problem but havnt found any good answers.
im currently using the f7d bios, but my problem has been there since ive got the motherboard. The optical sound out isnt working for me at all. analog is working as it should.. My vendor told me that they heard that it could be bios related. Just wondering if other has experienced the same as me. thanks in advance. (sorry for bad english)

[freqy]

sync internal on computer. frequency must be the same on both devices.
44.1k or 48k ect..

your amp or reciever must be on the correct optical input ( some have more than one.

what i would do is reinstal the drivers..but im sure you've done that ten times already. maybe there is a conflict somewhere?

re install windows from scratch ( dual boot so to keep your present xp)

if you can get the optical to work in a clean windows. then you know there is something on your other xp conflicting.

it could be your receiving device? the amp or desk your pluging into? can you test that with a mini disk player or something?

test with coaxial?
