Gigabyte GA X38 DQ6 Blog

This refers to the X48T CPU GTLREF but their basically the same as far as gtlref & bios go.

OK but the X38 doesnt have this option right?

Im going to my girlfriend now

She's not going to be happy ?
Yes it does
Their hidden you need to press [CTRL] + [F1] from the bios main menu to access them.
Thought you'd read the note at the bottom of the Gigabyte GA X38 DQ6 when you posted your settings, sorry

[StyX]

lol i checked your post at her place

I still cant get to start. I does get to the windows loading screen but hangs in the process. Stupid thing is that when i raised the CPU voltage to 1.3500 it wouldnt even show the loading screen...

These are the most maxed settings i have tried until now..

Normal CPU Vcore : 1.2500

Suggestions anyone?

[supershanks]

try

FSB OverVoltage Control : +0.10v

to +0.15v
also might try
Just try GTLref1 at -3 Gtlref2 at normal

If those don't work then try these:-
CPU Clock Skew Control : 100ps
(G)MCH Clock Skew Control:100ps

Are the settings as i described above a bit over the top for 24/7 use if i get it at 3.6? I mean; it's all a lot more compared to 3,4ghz... and for just 200mhz more....

[supershanks]

basically depends what your temps are, not sure how or what your cooling is ?
Somme can get 3.6k on air others can't. Depends on you basically. I generally top out with load temps at around 65C on prime.
With current stability as you describe it's not yet a 24/7 clock , but should be doable given your equipment and good cooling.
If you get 3.6k stable, but with high temps, it's easy to back off a bit to 3.5k say, whilst you persuade your girlfriend that you need water cooling

Thing is; the temps arnt the problem. I got a Thermalright 120 Extreme ontop of the quad and it keeps it nice and cool. @3,4 ghz it idles at around 30C and load doesnt even get near the 60C. It just seems like to get it to even start at 3,6 ghz, i have to raise a lot of volts everywhere...

i finally got it to start @3,5ghz but with the following settings:

Normal CPU Vcore : 1.2500

I got to login and do things but i completly hanged after a couple of minutes of Prime95.... Perhaps i should give up and wait for the next new bios. In comparisation to the 3.4 o.c these are quite big raises in volts for just 100mhz extra and its far from being stable....

Could still try the 100ps... you recommend those in combo with the -3% at the GTLREF?

[supershanks]

I'd put

CPU/PCIEX Clock Driving Control : 100mv

back to 800~900mv
try the
CPU Clock Skew Control : 100ps
(G)MCH Clock Skew Control:100ps

also try 1~2 extra turns on

(G)MCH OverVoltage Control : +0.125

If it's freezing , this is most likely to stop it.

If it's still unstable try an extra step on vcore.

Upping the MCH and the 100ps still didnt make windows startup at 3.6 ghz.... think i just need to start hoping the next bios will bring some improvements!
