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

[rioja]

Just entertain me for a moment, put the PCI-E frequency back to 100 & the NB voltage under 1.65v & see if slot 1 runs at 16x.

I had a similar thing with my P35.

no, it wont run as x16 in first slot with these settings, perhaps becoz of little overclock (400 fsb)
also i've found it may run as x8 in middle if i set 1.25v on nb

do u have 3870x2 and p35? have u seen any lockups sometimes?

[Bikerz]

I got 3.8ghz on my Q6600 stable, but any more and the system temp gets too much, CPU fine as in under water and only needs 1.44V for 3.8ghz

Never had any lockups with VGA sorry.

I only get lockups when I push the CPU too far & they can be virtually eliminated (within reason) by tweaking the NB GTL.

Hello gents (I would say ladies and gents, but let's be realistic),

Just curious- how high of a memory clock has anyone achieved with 2x2gb ram on this board? Most of the benchmarking I've read in this thread seems to (understandably) be with 2x1gb sticks. I'm running 2x2gb gskill 1066 sticks on the X48 board, and I can run the memory at 1128mhz semi-stable; can't seem to push beyond that no matter which strap I use. Haven't gotten crazy with the ram volts though...

Thanks for any input

Are you cooling the sticks with any kind of active cooling solution? And what volt settings are you currently using?

[drnick79]

I'm using the corsair ram cooler to actively cool. Stated manufacturer's volts are 2.1 for the sticks; I think at 1128mhz I set ram at 2.15 volts (my board undervolts a bit). I think I've gone as high as 2.3 volts but was leery of going any higher as I'm not sure what the memory chips are in this RAM and how well they tolerate overvolting...

It would be wise to stay where you are until you find out what chips are used by your sticks. Try loosen tRFC to around 50-52 and see if that does the trick.

Hey guys, a buddy of mine is having C1 Error read out on the mobo. He can't get any video signal or get it to boot at all.

DFI LANPARTY DK X38-T2R Quad Q6600 Kentsfield 2.4GHz CORSAIR XMS2 DHX 4GB (PC2 6400) GeForce 8800GT 512MB PC Power & Cooling S610EPS EPS12V 610W PSU hec RA455A00 4U chassis

We can't figure out what the C1 error is... searching leads me to believe it's either video or RAM (which doesn't narrow it down much). DFI's site is having problems (under construction)

Thanks guys.

reset cmos boot with 1 stick
then shut off from power supply +reset cmos n try till u get it

chek all power connections might be 1 pin not making contact properly

[TouGe]

Hello everyone. I have a quick question. I'll be getting my UT X38 this afternoon, ordered it from NCIX, and I was wondering if anyone here is using an Areca 1210 controller?
Does it matter which slot you use and is there anything I have to enable in the BIOS in order to get the card recognized?

Thanks.....

[Bikerz]

C1 is a memory problem. This board seems very picky with ram, wont boot with my OCZ ALpha no matter what you do, 1 stick, up volts nothing, just C1's so got some G skill now.

TouGe - 9 X 400 is 3.6 not 3.8.

[OnDborder]

I've been running this mb throught the ringer, for some "forumwars", and when I get the c1, due to too much or too little of something, I just turn it off/ restart it. Goes through a couple of startups then boots sometimes. If it doesn't, reset the cmos, and reload one of the "saved" bios configs.
Sometimes it hangs on "52", then I have to reset/cmos.

[ic3m4n2005]

OK flashed 111 Bios and played a little...
got me some nice results, but a a point i can't go further.
3200 are ok at 1.23 ..maybe a bit higher for the long run.
3400 not even stable with 1.4v, tried even very high vtt (1,6) and vnb (1,56) voltages, but it did not help
After a few mins prime i got a bsod.
Checked for fsb wall -> 8x345 no problem at all... so what's next ?
Any hints or maybe some presets to test ?

Quoting myself, maybe someone has an idea

Hey all. I just got a second 3870x2 that I installed on my DFI X38 mobo. With one card installed I got between 13300 and 13400 3DMarks. With the second card my score only went up by about 500 points.

Is there any way I can make sure both cards are working? I ran the Shader Mark test with both cards in and got around 1275 fps. Under "Details" in 3DM06 under "System" I saw this:

DirectDraw
Version 6.0.6000.16386 Primary Device ATI Radeon HD 3870 X2 Linked Display Adapters false

Unfortunately, I never noticed if it was on for one cards, but IIRC it was on for dual 2900XT's.

System info:
Q6600
DFI X38-T2R
4 x 1GB G.Skil PC_4200 HZ's
Two 3870x2's
4 x 250 GB Seagate 7200.11's
Thermaltake ToughPower 850W
Vista Business SP1

[ElAguila]

Are you oc'ing any at all? I have a Q6600 at 3.5GHz and both my X2 gpu's at 860/955 and I am getting 18K in 3DMark06.

[zanzabar]

whats your oc u need a high clock to feed the cards since the grafix benches are single threaded

[t_ski]

No OC yet. I played around with the CPU @ 3 GHz, but a jump to 3.6 GHz was not stable. I haven't been able to get it stable with multiple setups copied from this thread.

set memory subtimings dont assume auto is ok
in fine delay set timings dont use auto use relaxed n work your way up

i found clunk's gtl setting way better board is more stable n more responsive but gets hotter
for 1.52 cpu vtt
gtl1:125
gtl2:120
gtl3: 95
heres another chart

[Boyu]

update my mb to new bios but if i set CPU VID to auto or under 1.3 volt the option to select CPU VID special add become gray and can't be selected.But if i set CPU VID to anything beyond 1.3 the CPU VID Special Add can be access again.
Anyone having this problem as well?

anyone???

yes the board verry picky
i got 2 identical sets kingston with d9gmh only 1 will boot
2 sets of d9gkx 1 is flawless other 1
loves my ballistix 8500
like promos too
i know it gonna love your gskill

[Jor3lBR]

anyone???

Hey Boyu, thats perfectly normal in the new bios, stock volts they assume you don't need special add, only when the volts goes up a little that the special add becomes available...

The best way to know if they are working is to run GPU-Z and see if XFire is Enabled and then toggle between both cards on the sign...

Yeah, they're working alright. Problem is my CPU isn't fast enough (yet) to power them. Gonna work on the OC some more...

if that so,i can't make use of c1e auto vcore adjusting between idle and load when overcloking that need high vcore?.coz it's only work when vcore was set to auto.

What you mean?! As soon as you hit 1.30vcore the vid option will work.

As for C1E function combined with Special Add it won't work below a certain voltage (when undervolting)... It assumes your cpu already has the minimal amount of vcore to work.

If you unhappy why don't you just use the older bios that suited your needs?
