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

sorry mate i meant the 333/667 strap bios 1/11
just trying to run cas 5 @ 500fsb
i tried 400/800 get errors in memtest

what the best strap for running 1:1 @ 500fsb eva2000 ?

dfi x38 can't select straps themselves - what divider you use determines the strap you use.. not sure which one is used at 1:1 sounds like 266FSB strap ???

what settings you using ? template at http://i4memory.com/showthread.php?p=86150#post86150

if you set clock fine delay manually on other dividers, you need to use different clock fine delay values when you change dividers. So set them all to current value for clock fine delay, and then power down system/power off psu. Then turn back on and boot up at 1:1 will have different clock fine delay current values. Start at a lower stable 1:1 clock i.e. 480FSB or 490FSB and take notes of the current values as per http://i4memory.com/showthread.php?t=4743.

I find with E8xxx on DFI X38 at higher FSB and mem clocks, you need to be tuning the clock fine delay values in conjunction with tuning GTL ref volt values + CPU VTT. Errors and/or freezes in memtest86+ v2.00 when using E8xxx can be related to either or both incorrect clock fine delay values and/or incorrect GTL Ref + CPU VTT combinations.

Very tricky with E8xxx on DFI X38 to get fully stable at certain FSB/Mem combinations. Some combinations I luckily dialled in right settings for stability some combinations tried days to get right with no improvement heh.

It's a fine art hehe

Clock fine delay is very powerfull ... but it wasnt much rewarding for me, I guess I didnt use it properly ... nvmd,

Which strap(s) are the most stable ones and best for highest FSB?

[flexy]

i had bent the heat pipe was still getting contact i dont like contact lol and i wont bend the fins on my true
i get 32c idle on e6850 @ 4,0 and 34c on nb 36c on pwm

i just bent the pipe of the small NB heatsink, its doable. Its only a matter of 1/3 of an inch or so and the pipe is not that stiff. So you can move the whole NB heasink a bit back, carefully. Didnt have to bend any fins on the NB or the 120.

I've got a problem with my Cooler Noctua - it is impossible to install it, the same with AC Freezer 7 Pro.Heatsink of NB is too big, so I just instaled Noctua this way:
Is this ok?

[t_ski]

Yes, it should be fine to install that way, but people usually have the fan pushing the air through the heatsink. It looks like you have yours pulling the air through.

[flexy]

i sometimes wonder if i had better temps if i use my old XP-120 instead (with the fitting retention part)....since my case has a side vent. Then the CPU fan could draw in air right off the side vent.

[t_ski]

I have three 120mm fans sucking cool air in from the top across the CPU heatsink. That way I can swap the fans to the outside of the case and throw the radiator on top of them when I get the waterblocks out.

i think 5:6 then 1:1 is easiest to get high FSB

Does anyone know how the Zalman 9500LED will fit on this mobo with that NB heatsink? i mean i've searched then entire thread with no success.

Fyi distance from center of CPU to edge of the 9500 is 53mm if anyone can measure it for me.

yes it should the 9500 much smaller than my true

[Russian]

Thanks alot! Now, do you think that i could fit a fan on there? or am i screwed?

[zanzabar]

just put the fan over the 1st pci-e2 slot there is the same bandwidth on both, and the 9500 fits fine i had one before the enzo and it fit both ways with the fan and hs installed normally

[sparks]

zsamz I see you also have an antec 900.

I just ordered the board and a 120 extreme.

can you put a fan on the NB and the bottom of the 120 facing up ?

any room for the side case fan with the 120 in this direction?

got a pic LOL

Wait, so i can put it over the first PCI-E slot and put my videocard in the middle one and it will work the same? Sickkk. I love you!

[sparks]

I thought the middle slot was 4x ?

yes just gotta bend the nb heapipe a bit and cut 1 corner of the fan on side window:the window fan touches the fan on the true so i just cut it

Which is considered the higher end board? the UT or LT?

[GripS]

Which is considered the higher end board? the UT or LT?

Normally it would be the UT but since the UT never went into production for X38 it's the LT.

[Sparda]

Which is considered the higher end board? the UT or LT?

Yes UT is the high end board like DFI UT NF4 Expert/Venus. But for the DFI P35 LT and UT it just the nb/sb heatsink that differ. You can use same BIOS for both board.

i just moved my 8800 today one lower from PCIE1 to PCIE3 - gives me much more airflow from the intake fan. Otherwise the huge card literally blocks air to the CPU where its mostly needed (My case is weird)

the x38 has two PCIE slots with both x16 PCIE speed - so it doesnt matter. In addition i now have room for a 6cm fan on the NB heatsink, earlier the card was so close to the NB heatsink there was noway to put a fan there, not with the X-120 mounted vertically.

any change in performance?

I need some advice real quick.
I have a lt on hold and was finishing the order and 2 friends said NO get the Asus Maximus Formula.
I have an E8400 and wanted to get 4G everyday.
They said both boards are more than capable but you need to get the Asus because its an easier oc board. DFI settings are a pain.

True??


what do I get.... H E L P

If you wan't a easy overclock go for the Asus. Having extensive bios options is what sets DFI apart from the rest and would make a better choice if you want to get the max from your chip.

[Mikael4a]

how do you set tREF in the bios? or can it only be done by memset? and if so I guess you can´t use memtest to test stability sence with memset the settings aren´t applied before windows boot.

[flexy]

uh..AFAIK memset sets those in real time also right in windows.
