**Official DFI LanParty UT X48-T2R(and LT) Discussion

[cstkl1]

eh...
try this
reduce ure vtt back to 1.1
change ure nb gtl to 60
cpu 1/3 to 90
cpu 0/2 to 85
nb voltage at 1.4 since ure running 4 sticks
enable vdroop control
then just adjust vcore until occt passes..


445 bus on 45nm's c2d vtt at stock is still okay..


clunk do u know when dfi x48-t3R is coming out??
going to ddr3 ..

[xcluded]

anyone with 45nm quad , can you go above 420 FSB?

anyone???

thanks

thought this might be usefull for 45mn

All these GTL charts are great but what are our GTLs supposed to be? I understand that all boards and CPUs are slightly different but a good starting point would be fantastic. I've been all over the spectrum from 75-120 on my GTLs and i've been stable for a period of time in P95 in the whole range. I've upped my CPU VTT and Vcore to points that I think "should" work and then try adjusting the GTLs to dial it in but there seems to be no rhyme or reason for failure if I go up or down.

I had a really hard time getting my chip stable at 4ghz but after doing some numbers using the anandtech's chart for 1.16v for vtt i got it rock solid now.

Are you using the quad that's in your signature? There is a chart on anandtech, somewhere, that has VTT settings for quads that is a guideline for how much vtt to apply at a given FSB. You could probably find that and then get a good idea what your VTT should be in range wise then dial in your GTLs per the chart as well.

I just have a quick question.

When i start up my pc it powers on for about 4 seconds with nothing coming up on the screen. Then it turens off and powers on again about 2 seconds later. Is this normal? I am just worried i have changed something in the BIOS that i wasn't supposed to.

Thanks

That's usually the motherboard trying to recover from a bad overclock. You can set the option to how many times it tries in the bios.

that chart is for 45nm

every board every cpu is different you gotta test gtl settings
if you dont wanna put in the time to do so get an asus board
for 45nm its 61-63% for 65nm its 66-69%
gtl settings have to relate to each other by % +-1
you can alse go auto till you reach the max then you need to set them manually
some people have got upto 485fsb with auto i couldnt go past 440fsb on auto
gtl settings have to relate to the % +-1
dual cores are forgiving with quads you gotta be more precise
when i get my board back first thing i will do is measure all voltages n gtl voltages

[karateo]

can you please explain this?
thanks

[zanzabar]

can you please explain this?
thanks

the dfi takes time and tweaking to get your oc the asus gives u your clocks right away but ti wont go as fast or be as rewarding

[zsamz_]

5 months i still tweaking
when i get my new board i gotta start over
every board got a sweet spot
every board got different volts gtlvolts +-1-3%
1 thing for sure its not boring
hopin to break 555fsb but i dont do suicide runs lol

this is subjective
rewarding may be high stable overclock within 2hours of playing with bios

so, how asus works needing less time?
do the GTL's change dynamicly according to fsb or is it a fixed value set?

lol 2 hours not even after 2 months
yes i found my 24/7 long ago just lookin to make it better
you can set gtls to auto till you hit the wall then you gotta find the setting that will get you to the other side
setting the right gtl setting @ any speed manually will get you more stable
asus board is like driving atomatic tranny dfi like a stickshift
mind you i seen better performance on the asus
dfi gotta get its bios on track

I had to disable GTL to get stable but when i had a lower vtt i got crashes as with a nb volt of 1.4 but this could of been because i had GTL enabled with bad settings maybe.
It was late when i finished last night and was just glad to pass @ 3.917Ghz but 4Ghz is my goal.
Is anybody using GTL enabled with 1.16 or lower vtt and if so what settings have you got as cstkl1 & zsamz_ have given some answers but both are different values and with it needing to be disabled to pass its gotta be related .

[CoolZone]

any tests and temps with the UT version?

As previously mentioned I had problems getting 4Ghz stable but went up in VTT to 1.16v and used 82,79,63 (straight off the anand chart for 63%) and i've been stable since.

If your GTLs are way off you won't be able to boot usually.

I suggest having pen & paper and a boatload of time on your hands

[wilson]

@Pnot
I will try it and see if it helps ,also can you tell me what your nb and v-core is pls as we both seem to need the same vtt.
Cheers Paul

update
Ive just tried them with 4.0Ghz and got a code 4 2mins in i also got it with GTL disabled? Colud it be my vcore needing 1.38 insted of 1.36 but it seems high for a 4.0 Ghz oc.

hmm best way to eliminate ram and nb gtl/voltage and vtt
is by setting it in bios
and run WDMT or memtest86
until that is stable than only use occt
keep upping the vcore until u find stable with minor adjustments on cpu gtl.

i find this is the best way to clock on this board.

Thats not accurate at all. If a person does not keep the system on a ups, unplugs the computer, or loses power, the system does the reboot to reset the registers every time on a cold boot. Not caused by a bad clock at all.

This would be accurate were it a reboot, or the board never lost power.

Can anyone tell me what happens when the GTL are disabled? what is the default setting`s if any.

I'm pretty sure a page or 2 back someone answered this, may have been Praz. Just going by memory, I "think" its 67 for all 3, but don't quote me on it.

ah thanks mate u just worked something out for me . im memtest /occt 2hrs stable and prime.
but sometimes i have to turn pwr of at psu and pp, to drill holes, mod etc
then it reboots a cple of times when i start . i was thinking it still wasnt 100% stable, but now im sure it is. thanks.

Your welcome These boards can get confusing.

Yeah, I didnt understand why that was happening after my cold boots also. Thank for explaining.

That statement would be dead on if he was having bad overclocks as well. No one mentioned it being a cold boot with lose of power.
