It's already 52 according to memset.
I'll post a pic of memset when I get home -- hope to get you folks' input.
I hope it's not my ram :( I'd have to get rid of it and get me some 2x $$$ ram
THe mobo and CPU seem like they are winners :)

How are you guys getting by with your VTT so low???
I cant even get my computer to boot at 8x450 with my x3350 unless I upp my cpu vtt to 1.4
Unfortunately I don't even really know what VTT is... lol, other than anandtech's review said that for 450+ FSB requires vtt of 1.58 ? How are you guys cruising at 1.1v?
any ideas?
I actually just read anandtechs review... Really trying to figure out why I can't break 425fsb... I think it totally has to do with my VTT/GTL settings. I've been up to 1.5v and I can just get into windows @ 450fsb... That was last night when I didn't realize that VTT/GTL was that important... I was scared to push it past 1.5v but i guess its safe to up it more.
What is a safe high range for the VTT for 24/7 use?
Don't beat yourself up my friend there all on dual cores, quads need a bit more.
If you want to bend your head trying to work out what vtt is TTR have a good article that may help here http://www.thetechrepository.com/showthread.php?t=87
CN :)
Quad cores generally require higher VTT then dual cores. There is also less of a margin of error with GTLREF with quads.
This seems useful ... http://www.anandtech.com/showdoc.aspx?i=3129&p=13
i wouldnt use that anandtech article other than the performance levels
reasoning is
i had the maximus and rampage
their gtl is way off.. and hence higher vtt...
same proc on rampage i needed 1.184 vtt
oops wrong article
yeah that article is pretty good.
I've seen a lot of people got their hands on the DFI LT X48.Can anyone tell now which is the best board with ddr2 and X48 on the market in terms of overclocking for the QX9650?What should I choose?

Is it worth watercooling the southbridge on this board?
As i was thinking of fitting a Enzotech - Low profile Chipset block SLF-1 on it.
I will be buying mips blocks for the northbridge and mosfet.
Ok thanks for the imfomation :)
Just need to double check these blocks are the right one before i order them.
Northbridge.

I found I wasn't stable with x3350 (q9450) at 3.6 (8x450) until I had NB Core at 1.58v , is that consistant with what you guys are seeing?
I managed to barely squeeze my TUE120 vertically on the board and still get my entire IHS covered. It is a tough fit but it does work. I was going to mount it horizontally like in the pics i've seen here but i have a 120MM fan that pulls the hot air from the cooler out of my case. I'll take a pic when i get home with some more details.
I would like to know what aftermarket NB cooler to get for this just so i have some piece of mind.
Yeah I thought it was a lot!, just for testing I have my multiplier at 6x, so its not my cpu. Getting stable at 450FSB requires me to use that much voltage! (1.58v), could it be my memory? I have set the basic settings pretty relaxed, (5-7-7-18) could I be missing a setting that needs a lot of NB volts in order to run, (i tried upping my memory volts, but it didnt make me stable at all, only the NB volts made it stable.) BTW, I have my CPU VTT at 1.6v (because of reading anandtech P35 review and copying their settings for 445FSB)
It is interesting to see how does the TR 120 Ultra Extreme fit vertically after installing a Noctua U6 on the NB!
Has anyone with this configuration mounted vertically the TR extreme?

now with tweaking
awesome to get those 4 sticks at those low trfc.
CPU and NB GTL at 75,75,74 ( That should be default)
Reduced Vcore ( noticed theres a lot of droop on this board.. around 0.02v-0.03v on c2d.. must be more on quaddies.. any pencil mod?)
Ram setting change only 3-3-3-8 TRFC at 23 and performance level 6
ran memtest86 overnight 5 passes without a hitch..
Well, got my board in yesterday and it posted into the bios without issue. But, I was unable to ever get it to install Vista 64. It would hang, most of the times right after it initially loads it's first files (when the cursor comes on the screen for the very first time), sometimes right after I put the serial number in, but always a hard lockup. I tried it stripped down with one stick of ram, with the Areca 1210 in the 4X and 16X slots, with no usb mouse or keyboard attached, with nothing but the video card and 1210 installed. All with lockups. I had the bios at stock settings only, no tweaks, although I tried tweaking voltages to see if that would help (it didn't). I put the EX38 DS4 back in and it installed it without issue (and OC'd to 3.33 ghx as well).
Seems I might have recieved a bum board from newegg, unless someone else knows what the issue might be?
Shawn
Using the 9650 with Vista 64 be sure "PPM (EIST) Mode" and "Virtualization Technology" is disabled in the BIOS during the install.
I'll defer to Praz' wisdom. :D
I never tried disabling the Virtualization mode. If Praz' advice doesn't help I'll chime in.
I would say disable both the Intel and JMicron hard drive support though.
This X3350 seems to be an enigma...I was running it on my DFI LT LP P35 T2R and it is a bear to get stable at 3.6GHz (450FSB) without really cranking up the voltages. What is really interesting is if I run P95 small ffts it ran for an hour but as soon as I stopped and tried blend it failed immediately. That is when I started to up the NB core and vtt voltages. Finally I could get it to run blend for a while. And even more interesting is my Asus P5K-Premium runs it at 3.6GHz (450FSB) with only 1.3vcore increase and all other settings at their respective minimums.
Question about a Memory timing on This board. Has anyone changed the "Write Recovery Time" in bios, and had "Write to Precharge Delayed" change at the same time to the same value??
Both Memset and Everest show them both changing with the setting of TWR in bios. Problem is, my setting/s are both 13 at the moment with the G.Skill pc8000 2x2gb kit, and I am trying to tighten up my timings but only 1 at a time.
Is this a bug in the bios or...? I've searched in the memory section to no avail. Also, anyone have any sub-timings in which to compare for this ram? I'm only running them at 8.5 x 500.
Larry
Thanks for the advice, but it did nothing for me at all. No matter what I do, I cannot load Vista, period. I tried PS2 keyboard and mouse, different video cards, ram, with the Areca and without, disabling J-Micron, ide and ahci mode and nothing. It still freezes. It would appear the board is not right.
Shawn
I am seeing that exact situation!
I got too worried cause at 3.6 i needed 1.6 vtt and 1.62NB voltages in order to get stable, but at 3.5 (8x438), I have dropped voltages to 1.4V VTT and 1.4v NB so far and no problems, I'm still dropping the voltage as we speak and testing stability. Why is 450 FSB so hard? would a 333 strap vs a 400 strap be better? or what if we went straight to 460? maybe something is up with 450FSB on this board. Kinda like when the P965 chipset came out and the 380-400 FSB range was iffy, but 401 and up was fine?
My board I received Friday will not post at all :confused: :( , all my parts, CPU, Ram and so on are recommended by DFI for this board. I put everything back on my DFI P35 and all is well. The X48 seems to boot but I see nothing, running XP. Anyone else have this?
Note: Im running G Skill on the LT not the CellShock you see in Sig.
My mosfets were a bit hotter than I would have liked them to be. I took 3hours to take the whole rig apart (ifx-14 is such a pain in the...) and took off my stock mosfet heatsink.
I was disgusted by what was under the mosfet HS. I should have taken a pic. There was a ton of hard crusty grey thermal compound of some sort. It was fully crusted. I picked it off in chunks with the center post of a q-tip.
After cleaning up the dump that DFI took under my heatsink, I put a think layer of OCZ Freeze on it. My temps are down 20degrees.
If your mosfets are hot, go check your hs!
Yes, I did. I always disable those two things right off anyways. Like I said before, I really have tried every possible setting in the bios, swapped out hardware, tried different Vista install disks and nothing helps. I plan on rma'ing the board, so hopefully a new one will work out better.
Shawn
Shawn I think I'm going to have to go that route also. My board is just real flaky.
I guess this is the risk we take when getting the very latest and newest hardware. Sometimes it just doesn't work well the first go around. I am just hoping the newegg still has these available when I return it...
Installed vista ultimate 64-bit with no issues.Loaded optimized defaults in bios.Bumped up ram voltages.Disabled eist,c1e and vt.
not to start a flame or anything
but noticed two of u up there having gigabyte mobo's
if ure expecting this to be a plug and play mobo like gigabyte.. ure going to be disappointed..
takes a lot of work and patience with this board.. but the stability of it just amazing.. hands down.. awesome board..
not to start a flame or anything
but noticed two of u up there having gigabyte mobo's and wanting to give up on this board.
if ure expecting this to be a plug and play mobo like gigabyte.. ure going to be disappointed..
takes a lot of work and patience with this board.. but the stability of it just amazing.. hands down.. awesome board..
but i still dont get the purpose of the vdroop control.
if enabling it u get more droop.. then whats the point??
at least the maximus stops the drop almost entirely.
I could not install Vista x64 with the newest BIOS unless I underclocked. It froze at the first screen with a mouse.
Performance in Vista seems to quite poor. Everything is real jumpy and menus can take a while to load. Horrible compared to my Gigabyte P35 board.
:rofl: :rofl: gigabut :rofl: :rofl:
i gave up on gigabut last year " gave the crap board to my son"
terrible vdroop
terrible voltage control
terrible bios
most boards like driving automatic
not all people can drive n change gears
you want performance you better learn to tweek:p:
i tested 3 os systems today on dfi the best was xp64
i installed vista64 in less than 30 min
i think vista64 suks xp64 much better
dissable all cpu features but your cores
well no idea whats going on ure board
but no issue with any from of installation of os..
but again afaik usually failure of installation of OS is due to ram normally when ure installing on default..
seen this on multiple computer configs whenever i troubleshoot for ppl.
90% of the time.. its always been the rams.. either voltages, faulty rams, installed on the wrong bank, etc.
wait u said u didnt touch a thing but raid...
on jmicron or ich9r??
also have u tried first installation on HDD without raid..??
i am running mine on ahci on jmicron
and raid on intel ich9r.. no issue.. except i used the drivers on my usb floppy which was from the maximus since i already had a disk with it.
There is a hell of a lot of misunderstanding of Vdroop, what it is and why it's there. Vdroop is not a mobo problem, it's actually a design feature of Intel cpu's so therefore is part of the power delivery system of all Intel chipset mobo's. It's there to make shure the cpu get's the right vcore for what it is doing. If you have Eist, C1E and Vdroop control enabled at the same time your cpu will NEVER be in a position where it is being overvolted. You will also find that your PWM temps stay very low, in my case 38c under full Orthos load on stock cooling. Dissabling Vdroop control leaves your cpu open to large variations of vcore, hence the reason people complain of very high PWM temps.
This article helps explain vdroop & what it does/is, well worth a read.

I'm really glad a few of you have been able to install Vista 64 without an issue, but this doesn't mean that there isn't something wrong with our boards. So, go ahead and come on down from your pedestal.
As far as what board I am currently running, yes it happens to be a Gigabyte. But you might want to learn a little bit about someone and there experience before saying things like that. I have owned and operated almost every motherboard out there and have recently used the DFI P35 and the X38 motherboards. I know how they work and how to set them up. I just sold off the X38 last week, figured I had played with it enough. Also, DFI motherboards can operate at stock settings without tweaking. This is a fact, deal with it. If a simple OS install makes it freeze, at stock settings with kniown good hardware, then there are issues and believe me, they are not ram related either. I installed Vista 64 on the DFi X38 last week with the EXACT same components in my sig, but the X48 will not work? Board problem, not ram. Besides, apparently user cstkl1 didn't bother to pay attention to my posts. Go back and read them, you'll actually learn what I have done to troubleshoot.
Now, to pauldovi, sounds like we are having the EXACT same failure. Interesting. I'll let you know when my replacement board gets here how it works out. I'm willing to bet it will be just fine after that. DFI boards can be a bit finicky, but not like this, this is different.
As a side note, one good thing to report about the DFI X48, the Areca ARC-1210 raid card is recognised at 8X in the 2nd pci-e 16X 2.0 slot. In the DFI X38 it was hit or miss, but not in this board, so that is good news.
So the fact that at first it wouldn't even fire up is somehow my fault? The fact that I've tried every setting for the past 5 days with none working is my fault? The fact that my RAM worked perfectly in the GB but I'm now down to one stick in the DFI is yet again my fault? I've been on 4 seperate forums trying to get any setting that will work for me but nothing will. When can I say that the board is to blame? I have been building computers for 10 years now and have worked with 3 DFI boards so please don't tell me this is my fault. I'm glad your board arrived perfectly. When I got mine the battery was dead and when I replaced that the board still won't allow me to boot into it with anything but one stick of RAM. Everything is default the only thing right now that is changed is voltage in order to allow me to at least get into the BIOS and also into my old install of windows which is crashing about every 30 minutes.
I almost picked up 4x2gig G-Skill for my new rig too, until I read this:
"we don't recommend it to run on DFi X38 and P35 for now. it has problem."

After reading that, I decided to go with Muskin
Folks this is not a flame or rant forum, its a place for folks to come and get help and/or contribute. Leave the attitude out of the forums. Shawn and Clunky have legit questions and issues.
Bottom line, at stock settings all mobo's should work fine. I experienced this same exact problem, (when trying to use AHCI or RAID with Vista 32 or 64), on the DFI UT P35 with any bios newer then 11/07. I tried setting after setting except for turning off Virtualization support, which we shouldn't have to do btw.
I always ended up going back to 11/07 to do a clean install. BTW I experienced this on 3, count them, 3 different DFI P35 boards. Other then this one issue the boards worked great and I use them in my wife's machine, my work machine and my game machine. Unfortunately I killed my game DFI P35 and I'm replacing it with an Asus Rampage primarily because of this problem.
Any suggestions on running this memory at ~900mhz? I'm pretty lousy with mem timings so the only thing I've tried is upping the voltage on the NB to 1.4 (default voltage for @ 800mhz). I also upped the vdimm to 2.2 (from 1.8)
I have 4x 2GB stick (8GB total) @ 1:1 800Mhz
Here's a pic of memset:

Anyone else have problem with Everest? Eberytome i start it the system crashes. I have reinstalled it without any luck.
again i wasnt trying to flame or anything..
u could have corrected me anytime and hence u have..
sorries..
but i am amazed with this board..
way better than the maximus or rampage..
as good as the dfi p35 LT...
only only quirk with it in the beginning was the achi when i tried my 2nd installation with the dfi drivers on that disk. which is y i asked.
well hey i hope its just ure board issue and the rma solves the os installation..
this board definitely a keeper..
waiting for dfi fae to come with a bios to get the asus hd3870x2 top working.....
sishh that card only doesnt work on the foxconn p35 mars and this board..
i havent realize what difference there are between UT and LT...
there perfomance DIFFERENCE ?
or its only cooling ?
which is better ?
I will have my LT in the morning. :)
I canny wait.
I am having poor performance and stability issues. Not sure if it is this board or not. I have not touched the BIOS yet as I prefer to get Windows up and running before I do any overclocking.
Computer is 1 hour stable using Orthos (100% on all 4 cores, 4GB memory use).
However the second I start up ATI tool or Windows Performance Index the computer crashes. No BSOD, just a loss of video. I have tried changing video drivers and underclocking, but same exact problem.
I noticed today that DFI has newer INF files as well as SG files on their site in case anyone needs them.
Quick question to all, for running just sata opticals, do you guys have the JMicron enabled or not? I have them in IDE mode right now which is why I ask. I'm running a SCSI setup right now, so no sata drives installed yet.
Larry
Is anybody using corsair ram in this board like dominators 8500c5d ?
The UT (P35 Style heatpipe) has not been released yet & if the X38 is anything to go bye it may never come at all.
The LT (X38 Style individual SB, NB, PWM Heatsinks) is here now.
Both the LT & UT are the same basic board only the cooling mechanism changes so they should clock equally well.
As to which one is best well thats different for everybody, I personally like where poss to run simple & on air so the UT would be the board form me however water cooling fans prefer the LT's individual heatsinks.
Hope this helps.
CN :)
Ok I think I've reached what seems to be the max my mem will do: ~DDR850
3.4Ghz @ 1.2vcore (425FSB)
I could always exchange my ram for something better but the likelyhood of squeezing another 400mhz is slim, I think.
I COMPLETELY forgot the FSB on these chips is 1333 so I bought ram like it was 1066 :(. Live and learn, I suppose.
found a issue
cant get 800 CL4 1:1 TRD 7 to work..
weird cause i can get 800 CL3 1:1 TRD 6 stable.
on strap 400 and strap 333.
ahh ok :)
so LT have individual HEATSINK ??
and UT a more performance AIR COOLING life Rampage formula all in one ? ^_^
That's what my initial thought was but:
What I bought:
http://www.newegg.com/Product/Produc...82E16820231122
What I WOULD buy:
http://www.newegg.com/Product/Produc...82E16820231166
$159.98 VS $289.98! :eek:
Unless someone has some better ram for a lot less. I wouldn't consider downgrading from less than 8GB, though...
given up on strap 400..
it always comes at a cost of higher trd.
Newegg not so friendly returns anymore, now 15% restocking fee and you pay return shipping even if item is defective. I received my DFI X48 from them DOA and can not get refund even with the fact that its one day old, replacement only. On top of that I must pay return shipping. I understand the restocking fee and shipping fee on a new product you do not want but why do I pay return shipping on a defective product.:down:
If you know how to exercise you RIGHTS as a consumer and talk to the right people and documents all your letters to and from the store you will find that almost all of their return policy s are bullocks and they WILL pay for return shipping and they WILL send money or another exact item and they WILL not charge you restocking fee (this made me laugh do, Restocking Fee over a defective item, what do you think they gonna restock a defective item for).
Best of luck!
I'm slowly working my way up but I'm up to 3997Mhz @ 1.28v on air. I've left everything at default other than the volts on the cpu and 1 bump on the NB.
I'm trying to take a screenshot with SnagIT (my favorite tool) but i have black and grey lines running through the screen when i hit the print scrn key.. bleh.
Hey guys,
I am going to be purchasing this board soon along with 4x1GB OCZ Reapers HPC Edition 6400.. but i would like to know how would this perform with 4 sticks of ram? would it be OC'ing a bit better? Im also new to DFI and coming from a asus owner, had a few asus boards, p5k deluxe etc.. Want to try something different :)
or would i be better of getting some Kingston HyperX 1066 mhz stuff to give it head room hence 4 sticks?
Thanks guys
Can anyone post some photos with the Thermalright Ultra Extreme 120 mounted?
Anyone here also said they succeeded to mount this cooler vertically with the stock cooler on.Can I see some photos please?
Thanks in advance!
I just put mine together yesterday and the TRUE does fit well when mounted horizontally. It also allows you the option to run the NB HS passive as the TRUE 120mm fan will draw air through the NB HS fins. This is assuming you have a push system going on your TRUE. Mounting it vertically can be done but it comes at a cost. It won't mount in stock form, the top "shelf", of the NB HS, hits the outer heatpipe on the TRUE. I actually ground one side of that "shelf" by a few mm and it fit fine. The problem I then noticed was that getting good airflow to the NB HS in this configuration would be VERY challenging unless you moved your GPU to one of the lower PCIE X16 slots. This also comes at a cost of lack of good air to the SB HS. I decided that horizontaly would be the most ideal postion. Mounting it this was does decrease the aiflow to the PWM area but the heatsink is cool to the touch so I think it's ok.
I saw those,they are cool,but you have a case with the power supply mounted down,not up,like most of us.It is not very recommended to draw hot air into the power supply.If you mount the fan to push air into the NB cooler,you overheat the video card,which is already heated up.
Any other solutions to this?I wonder if all the motherboards with X38/X48 have this problem and cannot mount the Tr 120 Extreme vertically.From my oppinion,the vertical position is the ideal one.You have one fan that draws air from the case,cools the CPU fan,the PWM area,and then the air goes out with the help of the fan that is mounted on the back of the case.
If I choose to go with Noctua NH-U12P,will I have the same problem,or I could mount it vertically without a hitch.I am aware that the Thermalright 120 Ultra extreme is the best on the market.
Also,if I decide to replace the stock cooling with a Noctua U6,will I have the same problems or the mounting problem will be solved?
wasup, anyone are using the Thermalright HR-05 SLI/IFX NB cooler on this mobo ?
Hey Guys,
For these DFI boards, are there gonna be any new X48 from them? better then this one? and what is the average FSB you guys have clocked with this board?
thanks
Probably no future boards from DFI with X48.
One question:
which one of the P35,X38 or X48 is better with a quad?
There will be a DDR3 version of the board.
tnks zsamz_ nice pic ! u think this cooler is better than stock "heatminator" ? and what about the SB cooler, is fine the stock or change with the sli version :confused:
