Official DFI LanParty UT X38-T2R(and LT) Discussion/Review/Overclock/Guide Thread

[zanzabar]

u need the thinnest layer that u can get, and the best way for most things that ive found is to use a small amount in ball then smash it with the sink and it will spread out

[thezfunk]

Anyone using this board have one of their LAN ports go bad? The first time it went out I just reloaded the bios and that fixed it. Now it seems to be completely dead.

[novey]

there is a bug with "execute disable bit" fonction? i cannot see this fonction if it is on disable, i need to load optimized default to see it again

[Tuthmose]

Hey all,

My apologies for posting on this old thread, but I could use a little help here. No, that’s not true. I could use more than a little.

I’ve got this X38-TR2 that I’m trying to overclock. Please bear in mind that I am a noob at this. I understand the basics, but I don’t have experience under my belt, so I end up floundering when it comes to deciding if some settings are reasonable or not.

Long story short, I’m not able to get this board past 400Mhz at 9x stable. It often won’t even boot at 450Mhz (tried at 8x in case 9x was too much), and when it does, it fails Prime95 in fairly short order. Ok, stop laughing, I know my 450Mhz goal is very low by Xtreme standards, but I’m aiming low here. Just want to have her stable and running reliably.

The guts (same as in my sig):
DFI LanParty LT-X38-TR2
Q6700 G0 with a 1.3125 VID
TRUE with twin 120mm fans in push/pull
PC Power&Cooling 1KW SR
OCZ PC2-8500 DDR2 RAM: 5-5-5-18 @ 2.2V
Custom push-pull 50mm fan set-up over PWM to keep that little beasty under 60C
Twin fans on NB
Sapphire Vapor-X 5870

It passes several hours of Prime95 on all cores at the setting below. CPU cores never go about 60C, nor does the PWM, and the NB stays in the low 50s. Cores are measured with RealTemp, PWM and NB with DFI SmartGuardian. I’m thinking it isn’t a heat issue, since those temps don’t seem too bad for aircooling. I’ve set my GTLs at the recommended “little bit over 67%” – I think I understand that bit well enough. Maybe.

Ok, now that that’s out of the way, here is what I’d like to know:

1) Where am I going wrong?
2) Why, and what do I do about it (so I can learn something here)
3) What settings would you guys recommend to hit 450Mhz with this stuff, either at 8x or 9x? (Frankly, 8x would be just fine)

Thank you very much in advance for helping a noob learn something,

your gtl settings are way off
try 125 or 120 or 115
120 115 110
110 105 100

[Tuthmose]

Thanks for the feedback, Zsamz.

I’m confused, though (yeah, I know, that’s obvious). Do you mean I should change the GTL’s in my working 400MHz setting above, or I should use the GTL’s you listed to get stability at 450?

If you mean the ones I posted for my working 400MHz config are too low, could you clarify? Aren’t the GTL values for a Quad supposed to be set just a tad higher than the 67% referenced from this chart? According to that, the 67% values that correspond to my current 1.42 VTT and 1.479 NB would be 97/96 and 102 respectively. What did I misunderstand?

Thanks,
-Tuthmose

EDIT: Still have no idea how to get to 450MHz, but I did get it running stable at 400*9 with lower VTT and NB (1.36v each) along with commensurately lower GTLs, dropping my temps. The failures to boot at anything above 400Mhz FSB throw a C1 error, so that's something I've not set right with memory, right?

just set em and test
or read the whole thread
the right gtl setting will get you stable highest fsb and lowest cpu volts
you should hit around 450fsb

[Tuthmose]

LOL - believe it or not, I HAVE read the whole thread. My eyes crossed a couple of times wading through it I've tried some of the settings folks posted that are close to applicable for my cpu/memory/cooling, but no dice. I don't know enough to know why, is the problem.

When it won't boot, it's a C1 error, for whatever that's worth.

I'll just keep hammering away at it. Am I in the right ballpark with the 68%-71% GTLs?

Thanks,

[AKHandyman]

I just resurrected the DFI LanParty X38-T2R board for a friend. Board will NOT go into sleep mode. Just won't ... I can't remember if there was a patch or fix for this problem ... anyone remember?

Flash from the past ...

[zanzabar]

do you have speed step and s3 enabled?

[AKHandyman]

I have S3 enabled but the speed step (ESIT) disabled. I've tried a various number of combinations but all to no avail ... Sorry, but at my age, I forget a lot. I just vaguely remember something about this issue and I can't figure it out.

Hopefully someone will remember or give me some directions ... BTW ... thanks for replying ... old board, I know, but this is for an old friend and I don't want to throw a $$$ or time into this build.
