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

If your memory allows to set Performance Level to 9 or 8 it will drop down your latency, but you may lose stability and even can show you a nice blue screen

Altered my sig to reflect correct bios.

quick question about a psu I see in your sig...
isn't it noisy? because I have the same and DAMN...

[ChrissTi]

What do you think about that guys ?

Yes, very noisy....but a quality PSU none the less

That pic is of the 965-DQ6 mobo, there is no Rev 2.0 X38-DQ6.

Still bios problem ...

[century child]

Well I finally found a place that has the XFX 780i board in stock so I pulled the trigger on it. Should have it by the weekend at the latest. I've got high hopes for the board and am looking forward to seeing how it compares to this board with my hardware.

[Caped Crusader]

HOLY CRAP!!...i got a MASSIVE boost when i altered the subtimings using memtest:

With default subtimings i was always just under 8000MB/s

Thanks to CapedCrusader for the guidance:

good for you dude glad I could help.
since you have the same sticks as me, I don't think you'll have any problems getting the same speeds I'm getting here. My mems always run with 'performance level' 7 at 1080Mhz, so you can tighten those babies a bit more

I also dropped the vDIMM to 2.05 (from default 2.10) and they're running great!

[Frostybyte]

Well it's a new day and more strangeness... btw thanks for the input guys!

Last night, I just shut it off when I couldn't get the thing to post while overclocked... then went to sleep.

Today I tried it with exact same settings (and each stick of ram seperately including the single good crucial) and they all work stable in memtest for 10 minutes. This leads me to believe my motherboard is giving me this problem and it could well be heat related.

You guys reckon my northbridge could be overheating ? I could easily connect a block I have to it using my second water-cooling loop if that turns out to be the case.

[Frostybyte]

Hey guys, I just noticed my naked ram is getting so hot at 500 mhz 5-5-5-15 that touching it even briefly will burn my finger!

I don't remember d9gmh getting that warm, is this normal ?

Also, I reckon you're probably right about the CPU needing more voltage Chrissti. I've upped it to 1.5v for now, going to test for stability tonight.

[ChrissTi]

WOW I've seted my memory timings to the timings like Richard Dower's on memtest (mine were tighter) and now it works on 1080 Mhz . So it seems that the SPD timings are the problems on the memory modules. Other memory manufacturers, just have the memory timings more relaxed. Now I have read and write over 8MB . Now I'll do more testing to see if it's stable.

[ChrissTi]

Found a bios bug. If I set some working timings in mutilpier 2.4B (1080Mhz), when I set the multiplier to 2.0B (900Mhz) the system doesn't boot

[MightyAA]

Is there any trick to get all four sticks of my Mushkin PC2-8500 to work with this X38-DQ6 mobo? I've tried several bios's back to the F3.. but found F7h most stable.
Right now, I'm sitting at:
Q6600 (g0) @3690 (410x9) @1.55V
two 1gig sticks of PC2-8500 @ 546.7 MHz, 3:4, 5-5-4-12-2T @2.250V

stable with 24hr OCCT run.

If I put in the other two sticks in, OCCT will crash within a couple minutes and I'll get errors in memtest almost immediately if it makes it to windows vista's desktop at all. The closest I've got to stable with 4 gb was dropping down the strap to 2.00 and the FSB clock to 360-380... I've tried loosing ram timings and increasing voltage beyond spec, but that didn't help. Any trick to this? I'm ready to throw in the towel...

[ChrissTi]

MightyAA try rising voltage by 0.1-0.2 and you have to set more relaxed timings ...
You should've bought 2x2 gigs instead of 4x1.

[ChrissTi]

MightyAA set cpu to standard frequency, then try to rise the mem strap till you get close enough to your desired mem freq, and do a memtest, then rise cpu voltage till you got stable mem.

[ChrissTi]

MightyAA forgot to tell, try rising MCH voltage with 0.100 at least

[Caped Crusader]

Damn, the cold boot bug has gone! I left the PC switched off overnight for the second consecutive night (one night PSU off, last night PSU on) and it's gone!

I did as recommended by someone here (sorry I'm bad with names) and switched my Enermax to a PC Power & Cooling 750 unit and it's working like a breeze. I'm even able to lower the vcore and still boot into Vista and run apps and games stable! Thank you! PCP&C rulez yeah!!

[century child]

Glad that worked out for you too Caped Crusader. I noticed the same things when I changed PSU's.

[ChrissTi]

Caped noise levels under full load?

[ChrissTi]

Found what is the problem that we have to increase the cpu voltage ...
This mobos take the CPU current from all PSU rails 3,3V, +5V and +12 V.
The power neded to overclock the CPU is more then 135 W. So the rails must give minimum 100 A ( I=P/U= 135/100=1,35V (The CPU voltage ), otherwise we have to increase the voltage to compensate the current neded by CPU . So a better PSU is this:

Interesting...could somebody buy this thing (only 499,99 $ ) and then tell us how it performs? Must be nice to have a 90 ampères 12V-rail, but 32 to 44 dB is a bit loud...

[Caped Crusader]

Caped noise levels under full load?

Well, I don't have any db sensor to properly evaluate, but I can tell you this: I didn't noticed any noise increase from my Enermax, which had a 120mm fan. Noise is pretty much the same when playing games/stressing CPU+RAM or whatever. I didn't noticed any fan speed increase when on load either. Doesn't bother me too. Right now, what's making the most noise inside the case is the intel stock cooler, but I'll change that next month or so...

GA-X38-DQ6 - BIOS Version F7

Its not up there yet, but it seems F7 is about to be released

[ChrissTi]

and another very good PSU

I would buy one of this babyes but unfortunately I couldn't find in my country ...
