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

does anyone know how low should set fine delay to? is lower better? and should i have it on "more aggresive" while its unstable or would it be better to have it on auto till its stable?

is there any official review on UT X48-T2R ?

Thanks

It's not officially out yet, should be around June along with the P45 UT :D

I asked DFI EU and they told me, that the board will be available tomorrow. If they told me the truth, my board will arrive next week :)

my question is wouldnt setting fine delay to relaxed have the same effect? or am i better of reducing memory speed abit then reseting fine delay to match stable settings?

edit* relaxed settings didnt do anything, so forget that q's . still unstable with occt. im trying what u said and i reduced my memory speed. but i had to reduce fsb to reduce memory speed. how can i reduce memory speed only? it doesnt seem to have a separate setting for reducing memory speed? i overclocked using strap settings and increasing fsb i didnt increase memory manually.
also is occt to strict? seems stable with prime but looses out with occt.

Clock fine delay isn't a performance setting like subtimings. The lower clock fine delay values don't mean loose settings at all - they're just values which need to be tuned to match your memory/mem divider/mem timings optimally. OCCT and prime95 test different things only way for true stability is test every app you use.. you can only say a cpu is OCCT or prime95 stable if you only use one app heh.

Lowering fsb to reduce mem speed is fine in finding clock fine delay values.

They were waiting for parts for the coolers, maybe they came in stock earlier than expected, but the ETA was June :)

Is there any gain between the LT and the UT or the only difference resumes to more work to take the heat sinks apart on the UT? :ROTF:

what the max FSB Touched ??????????

this motherboard can do more than 600 with liquid on chipset ?

no diff between LT and UT only NB/SB/mosfet cooling heatsinks being different

just need to replace bios file n an older awdflash
x48 bios n x38 bioses are the same with x48 bios you get more juice to nb

Just did this one, getting there :)

very nice info clunk, read that whole thread :up:

I also saw your review of the board with the geil black dragons (2gbx2). Anything past 3.6Ghz lands me either into code 1 with OCCT or corruption/firefox crashes. Would that be the RAM timings? I have gotten it to boot into windows up to 4.1 though. Any suggestions for 3.9+ stable?

Hello all,

I am considering buying this board as it seems to be the best clocker and I am using water.

I am not sure however which brand of memory is best for DFI, since I never bought DFI in the past and have been using asus always.

For some reason, I like corsair ram and quality and been think to get 2 kits of 2x2GB 8500C5 dominator for a total of 8GB RAM.

Do you think with 4 sticks will be harder to overclock? Do you agree that corsair will work nice with DFI (and this board) or should I get something else prooven to work better (no experience here).

Finally, I have -NO- clue how to tune/setup this board and I keep reading about GTL and LOTS of settings you guys change and tune and being an asus newb myself (and AMD!) I feel lost.

In summarry,

Is this the "best" overclocking board for now?

Is corsair a perfect match for this board?

Is a Q6600 or Q9xxx or X3xxx series cpu fully compatible and will overclock best with this board?

Thanks for your input as I trust the experience of members here to decide on my parts :)

thanks, ive lost my stable overclock now anyway. having 4 sticks its damn hard to get stable past 450/1080 ive tried everything i can. i read that edge of stability , but couldnt understand any of it. it really needs to be translated into english lol.
my pc had a nervous breakdown and has reset its bios. i even lost my raid0 for a while but i have it back now. i guess its back to the drawing board.
if it doesnt work ill have to get rid of those cheap and nasty crucials.

are there any guides around for clock fine delay? like a "clock fine delay for dummies" guide? i really cant get my head around how it works. gtl isnt a problem becuase i just follow clunks chart but clock fine delay is a bit of a mystery for me. i did google it but this thread is the only thing that comes up.

so has it been established that the dfi x48 can clock better than the x38 mobo?? im thinking about buying this one.. but i own the x38 now... any advantage at all?? thanks

I own both and this is what I can say:

X48 can clock same OC with less voltages (nb and vtt) then the X38.

OC is slightly better but I suppose it may be due to other factors.

great info guys thanks for sharing.

I'm now running 8GB and 9x420 and I think I'm also "getting there". Previously I would get random BSODs, but after tweaking all I got was one core failing in prime (FATAL ERROR: Final result was xxxxxxx, expected: xxxxxxxxx), the other 3 are still running after 13 hours. I upped the NB voltage to 1.555 from BIOS, set the latencies a bit more loose, and upped the cpu voltage a bit. I'll try tweaking the NB GTL value now if it has any impact.

Did a 5130Mhz one here.

Nice way to end the review :D

Hello everyone!
I just got this board today but im having the same boot problems that i had with my Asus Rampage. Board beeps when i put memory at slots 1-2 (1-2, single 1, single 2, 1-3 or 1-4 etc... all fails to boot C1 error) but if i put the memory at slots 3-4 or just single 3 or 4 computer boots and works great.

Both board i tried this memory were x48 and i tried on other board and memory works great, so i guess its this a x48 non-compatible issue?
Memory is Geil Evo One PC8500 4Gb pack (2x2Gb).

What can i try? :down:

Send the memory back and get a different brand?

Edit: There is a problem with some OCZ modules and ths DFI X48 and they provide a fix whereby you have to reflash the modules yourself, so maybe this is a similar issue, might be worth contacting Geil to see if they have a similar solution?

closest would be my info at http://i4memory.com/showthread.php?t=4743

Just think of clock fine delay like GTL tuning only difference, is there is no set table to go by like GTL. each memory module, different mem divider, mem clock speed and timings will alter the clock fine delay values. The info at http://i4memory.com/showthread.php?t=4743 just sheds some light on what to do when you hit a memory clock speed/instability ceiling.

Use http://i4memory.com/showthread.php?t=4743 with memtest86+ v2.01 to figure out initially what clock fine delay values will help lessen or eliminate memtest errors.

Weird part is, now i tried QX9650 first time on DFI LT X38, i find it helps stablise FSB too 9x445FSB 32M pi stable so far at CPU VTT 1.28v - no need for crazy CPU VTT volts >1.5-1.6v :)

I was going through some FAQs in the water cooling forum, and one of them mentioned not WCing the NB. Now maybe it's a few years old and attitudes have changed, but if I'm going to WC the CPU and I want to hit at least 450 FSB (anything higher is just gravy to me), would WCing the NB be a very good idea, not really needed because of the stock NB air cooler, or a certainly can't hurt and looks better idea?

I have my northbridge watercooled, seems like common sense when the MCW30 northbridge block is only 25$ or so. Helped lower temps on my chip to around 30c with a terribly sloppy mounting job (put it on with hoses connected :X).

i not have problems in connected my MCw30, I used hard mount, and the temps around for 30c

Newbie question here guys, apologies & feel free to laugh & point at the idiot:

I've just bought the LT version of this board this morning & have only just put it together. I had a small problem in that my OCZ RAM cooler was in the way of fitting my 8800GTX into PCI-E slot 1, I've now fitted the card into slot 3 which I believe is the other full width slot.

Never having had to do this before does anybody know of any issue's it could cause or am I fine using this as my primary & only graphics slot?

I've got a lot of reading to do on this forum so thanks in advance to all the people who're going to give me advice in the last 34 pages :)

I think I read somewhere here that you should keep Graphic Card on either PCIe slot 1 or PCIe slot 2. But I might be wrong.

Why can't you use PCI-e slot 2?

Cool, thanks for the photo Clunk, I'm assuming that I'll be fine then? :)

@ Jor3lBR: Briefly reading through the manual it seems that you'd never get an 8800GXT to fit into PCI-E 2. I think we're talking about the same slot anyway; the 4th physical slot down.

Yep, that's how I had it set up for most of the test in the review.

Great review it is too! So many different settings compared to my old Maximus Formula, I didnt know where to start to get to my 24/7 3.6GHz. You did me a big favour there! :)

yeah thanks i did read threw ur guide , its good info . but the problem is this bios wont allow me to set it the previous stable settings. sometimes the settings could be more that 50 in difference. i tried setting them as close as possible but it just became even more unstable.
other thing is it was stable at 40. 200 etc very low settings. i increased fsb and used similiar settings. then it was unstable. now i started again and got to the same fsb and every setting was identical. but fine tune delay was stable at oposite settings ie 1246 311 etc. its weird that it can be stable at a low 40 or so then another time be stable at a high 1246? with the same fsb and volts and timings.
anyway im at 475/1140 again on occt but only for 2hours after that i get a 12v error which i heard is related to nb . so ill up my nb to 1.6 and see if that helps. i have my vtt at 1.553 i just couldnt get stability any lower.

High VTT:s could kill your CPU. 1.45v was the maximum amount, recommended by Intel engineers. More on that subject here: http://www.xtremesystems.org/forums/....php?p=2923870

wow thats good to know. i didtn know that . i might set it back to 1.45 even though i know i couldnt get stability at that settings. im just trying everything i can to get this system stable with 4x1gb. seems almost impossible.

Got my kit arriving tomorrow. Cant wait to have a play.

Will let you know how I get on! I'm already very tempted to get active cooling on the northbridge.

Why would I want another P35? the P35 does not support pci-2.0 and the 2nd pci-e 16x slot runs at 4x. I like to run my areca card at the full 8x speed.

hey clunk i saw ure review

hmm i have the same proc

for 500fsb u used 1.2vtt??
nb???
and left the gtl on manual right??

cause i seriously think the gtl on auto is way off...

will post my result soon to show this..

thanks for the guide, makes it easier trying to work this stuff out when theres a guide. but i have to say, that it would be really good if manufacturers released there own guides with motherboards that are promoted as overclocking boards.
i know i would pay an xtra $100 for a detailed guide on how to get this thing stable. if i had to choose between paying an extra $100 or the stress of hearing that duck noise every night after two hours of occt and waiting to see if uping the nb worked. id choose paying the xtra money anyday.

yeah 1/11 and above bios don't have manual exact clock fine delay values to the current/auto values but just set it a bit above or below.

While you haven't found your optimal values, it still illustrates that tuning clock fine delay can effect stability of your memory clocks. Just need to play with it more.

Another tip is swapping the memory modules around in same dimm slots as well and playing with optimal clock fine delay values

Wow, nice guides Clunk, this'll give me some reading to do before I slap it together on Friday.

edit:Oops, I was actually sitting around at work today thinking...did I typo the name in that message? :)

hmm memset doesnt detect tRTP properly for this board.
everest reads the same as memset

set tRTP = 2 memset reading 4
set tRTP = 3 memset reading 5
set tRTP = 1 memset reading 6

FeLix hmm i tested it a few times..
memset and everest reading is wrong for this board

i thought for 4ghz u would need atleast 1.4v thats amazing. and a 500fsb/+4x1gb @1000mhz? thats pretty cool, ill have to take ur advice and lower my vtt. i thought the higher vtt the better for getting above 450fsb. guess i was wrong.
any chance of getting template of ur settings? not to cpy but to see where im going wrong.
there wouldnt be a huge difference between an e8500 and and a x6800 when it comes to voltage needed? ive got mine at 1.49v im not happy about having it so high but i want stability.

well yes but the problem with the vtt voltage for 500 fsb is not the CPU GTL's
its the NB Gtl's
will post my template and u sill see what i mean.

Example for Default leaving it at auto i need 1.4vtt and NB at 1.67 voltage
changing GTL to 70 i need vtt 1.2, NB at 1.63v
and the current gtl as follows
so i guess mess with lowering the NB gtl.. not too sure as how the 65nm would work on this board as i dont have any left..

Felix here is another one
Set tWR to 11.. memset reads as 10
Set tWTR to 14 .. memset reads as 13

Well this setting is rock hard stable.. kekeke..
when i ran occt for 4 hours it was running 99.60% CPU load

for others 45nm C2D.. just change the vcore my guess
and for ure rams if 2x2gb just change to 5-5-5-15 Performance Level 8 and Leave the tRFC to auto
This board gets better and better once u know what ure doing ..

oh man thats like gold to me right now. ok im going to start again, i might have to keep a higher vcore than urs though as i doubt my x6800 will like 1.31v. i noticed ur fsb is much higher than mine to so ill up that even more.
i thought u meant cpu vtt i see what u mean now. ill reset my nb vtt see how it goes.
thanks alot for that .
ps- im also shocked that ur core temp is only 15c ! im on water and occt on 90%plus load has it at almost 60c!!

update.. i was a bit suspscious of the tWR and tWTR setting as i coudlnt remember what i was running at for the OCCt 4 hours..

checked and rechecked
that memset reading 9 and 12 is unstable..
so the last two benchies is actually unstable.3dmark06 and everest

changed to setting 11 and 14 memset read 10 and 13

those thats .. thats the coolit freezone elite on mid setting working..
heck i usually have to run it at low..for 24/7
and for benching at those voltage mid

living in malaysia.. so will get serious condensation issues

will post my result soon to show this..

Yes, you don't need a lot of VTT for a Wolfdale. I was using the stock 1.1v right up to 500FSB and at that point it needed 1.2v.

No, the GTL was set to disabled for these tests.

The GTL ref values are intended as a ball park figure, because your own board will probably measure slightly different to the one that DFI used to get those tables.

If in doubt, grab a DMM and measure the voltages of your board, it's the only 100% way to do it really :)

ok ive got my vtt set at -
-1.453
-130
-120
-for nb gtl i have 70 instead of 100. i lowered it somewhat .

vore- in bios reads 1.49 in smart gaurdian its alot less its 1.47
nb -1.52 smart guardian
vdim -2.2
i had these volts alot higher and they gave me occt stability for 2hours. but now i lowered hoping its still stable. occt is running now.

new here!
with the latest official bios, it seems that the special vid add is not enabled. Am i right?

The vcore needs to be above a certain amount before you can access the Special VID now.

It appears to be when the numbers change colour, then you can access it.

When my UT board gets here I'll ask that the Special VID Add is changed back. Oskar was able to do it for the P35 board when I asked.

my mushkin xp8500 are a pain on it "d9gkx" c1 on coldboot and can only run cas 4
my kingston hyperx 8500 "d9gkx"getting c1 on coldboot

What heatsink are you guys using ??

That's a bit odd mate :confused:

I used a set of Tracers and a set of Ballistix, both 8500 D9 and they were fine, the only problems I had on my X38 that were similar to yours were when I had a dying stick of RAM.

Don't know anything more then anybody else as to a firm date. What little I've heard puts the board around mid May.

The Special VID Add is a big deal for me. Except for benching I'm a believer in using VDROOP the way Intel specs it. Makes life much easier on both the processor and the power section of the board. But without Special Add idle voltage is unnecessarily high.

I got the board today with a new WD 2500AAKS hard disk.

I have connected a raptor-x, 2x 2500KS, 1x 2500AAKS and a seagate to the ICH9R set as RAID in bios.

Now, my problem is that I cannot make all of my drives to perform at maximum (talking about random access time).
Sometimes my new drive gets 13ms but most of the time 16ms
I tried to swap a cable with another drive but then the old fast one got 16ms and the new "crap performer" scored 13ms.

I thought it was the sata cables...nothing changed when changing ALL of them.

This is my 3rd dfi motherboard! Two P35 and this one (X48 LT).
Has anyone else experienced something similar? Can someone reproduce my problem?
If I can't get it work by tomorrow I am going back to ASUS :(

for my proc i can use it above 1.2v
here is the catch if u guys want to use it rather than increasing the stock vid

example for my case
go higher than stock vid auto setting
then increase the special vid
and then change back stock vid to auto..
kekek it works..

but the vcore still overvolts on bios and cpuz reading
vmm shows different story that its about 0.02-0.04v less

I just spoke to Jimmy at DFI and he said that the reason they set the Special VID to work >1.2v is that when the Vcore is under 1.2v, there can be additional ripple caused if the Special VID is used, so to avoid any power issues, they decided to only allow the Special VID after 1.2v.

That's all the info I have, hope it fills in some blanks :)

all my sticks 100% mate my board just too picky
i'll run the ballistix if they die i'll just get some gskills
i'm running 4x1 now 511fsb need only 2.1v 1226mhz

this board just loves my balistix tested 2.1v for this

Ok, got my hardware in today, thumbing through the manual, I had 3 questions.

1) This is my first water cooling job, will the system freak if it sees no RPMs on the CPU and NB fan bus?

2) I assume the port marked LAN port 1 is the one I want to be using? Whats the difference between the 2 marvell chips?

3) Regarding the 2 FDD connectors on the mobo, if I'm using 1 video card, should I have 1 or both plugs plugged in?

Thanks.

QFT! :up: I also believe in safe overclocking for 24/7 use. Except for benches having Vdroop makes sure the processor gets the right amount of power.

Hey guys,

I'm having some problems with subtimings with these 2gbx2 pc28000 g.skills. I cant pass stable at 500 without errors or corruption. I'm almost positive its my subtimings, since I set some to auto because of countless options for memory on this board. Any suggestions for some of the finer ram timings?? Using 333/800 strap for now, but would like to move to 333/667 after I figure out these timings.

eh u do realize the the amount of NB and ram voltage u going to need at the lowest trd for 333/800 at 500 fsb 1:1..heck i even wont go there unless the latencies are right...

i suspect all ure voltages is unstable.. NB and VTT..and VCore..

500fsb 1:1 333/800=1200mhz i doubt they gonna do that speed slight chance if they were pc2-8500

Hey Clunk. Great job with the review....
Just shows that your hard work and good information
is much appriciated.

Top Notch :up: :up: :up: :up: :up: 5 thumbs

can anyone confirm that the Corsair CMXAF1 ram cooler fits ok after installing a TRUE on the CPU?

"DFI is proudly to announced this great honor from Clunk.org.uk ....."

If they could only bang out a sentence right we'd be set =P

Great work Clunk! I've read all your reviews and settings for a while now and i'm about to start playing with my system again.

hey clunk since ure in dfi's good graces
can u ask frankie etc
1.whats with the ovevolt reading on the vcore..
the x38 didnt have this issue.. atleast the board i tested didnt on the same proc

if it wasnt for that would have rated this board the best board i ever had
till the then maximus se flashed to rampage bios still rocks.
the striker formula 2 is not bad also

My X38 had it, and so did the P35 that I had.

I'm going to have a poke around later and see if it is just the software that is reporting wrong, I will report back with my findings later on tonight hopefully :)

I will ask DFI for you as well.

thanks
another weird issue just cropped up
1:1 500fsb CL4 TRD 7..

it suddenly didnt work and was causing so many failures
heck even cant boot

tried 3 different sticks..
Team Xtreem PC2-6400 CL3's
Team Xtreem PC2-8500 CL5's
OCZ Flex PC2-8500 CL5's

even at 2.4vdimm also no effect

all of this had no probs with the maximus running at 1000mhz CL4 at 4.5ghz!!

it start with some boot manager issue on boot from restart
then it had trouble entering windows
then i reran windows mem diagnostic tool.
it failed in 9%
all of the sticks. from 1 stick to 4 stick config since i have 2 pairs of each with the same batch serials
so had to back it down to 1000mhz 5-5-5-8 TRD 8 rest same as the template 1.5vNB, set 2.00v dimm.
passed 10 passes for Team Xtreem PC2-6400 CL3
2.03vdimm for ther other 2 at 5 passes..

trying to figure out what happened.. it all started after sleep mode last night i booted up.. restarted and just loaded one of the profile i had for 500fsb saved..

till now cant get CL4 to work ..

update
heck now even the proven 3.8ghz 400x9 266/667 1000mhz CL4 2.3 also is having failures.. what the hell..

will be reflashing the bios

I'm desperately trying every strap, because I'm having troubles even posting with 5-5-5-15-64 trfc at ddr2 1000. I have also tried other straps but no luck. I KNOW its the memory though, as I think auto is setting some of these settings too tight, even though only 4 or so settings are on auto.

If all the sticks are doing it, it sounds like you could have corrupted the CMOS.

A battery out CMOS clear fixed that for me, good luck :)

Congratz Clunk and thank you.... :up:

Well done clunk :up:

Its real nice to see DFI back big time in the UK, I was only moaning a month or so ago that it was imposable to get any DFI in the UK.

Well done DFI :up:

Have been playing with the new parts all day and have my E8200 running at 4Ghz although its not quite stable yet. I think I need to learn and understand some of the more mystic settings in the BIOS.

Very impressed with the new DFI board so far. Havent had to do a manual CMOS reset once yet :)

Havent had this much fun since the last time I built my AMD setup!

Lots of X48 UT pics -> http://www.pcgameshardware.de/aid,64...=641312&page=2

Looks so cool.......i love this board

thanks clunks..
sishh so used to the asus rog mobo's
cant remember the last time i took out cmos bat
must have been when i was using my 939 nforce 4 mobo

Great job Clunk, you definitely deserve it, along with some upcoming mb comps. :D

Axis

Great job Clunk! You are the best ! You helped lots of us !

I have another little question.From where do you think these guys got the UT version from?

http://www.pcgameshardware.de/aid,64...=641312&page=2

just booted the board for the first time and I like my NB temp with my mc30.

i think that this motherboard totaly suck.

i tryed boot with my e8400 ( that can do 620 fsb on commando)
all ok first boot.

450 OK
480 OK
500 FIRST PROBLEM ---> no boot, i tryed 1,65vNB - 1,45 VTT - 1,6 vSB - NB GTL 80 ---> OK BOOT
510 NO BOOT
520 NO BOOT
ecc...
over 500 i puts the chipset on liquid cooling to be more safe, i give em 1,88 vNB - 1,7 vSB - 1,6 vcore - 1,6 VTT!!!!!!!
ram was 400/800 1040mhz 5-5-5-18 2,3v ( crucial pc8500)

OMG

this is not overclocking
this is lotto!

i can boot at 500ish with 1.15 VTT with E8400

yeah ok. and VNB how much ??

GTL voltage ??
