**Official DFI LanParty UT P35-T2R Review/Overclock/Guide Thread**

[kberguy1]

I just setup a new system around this motherboard, and found that Speedfan, TAT, and Core Temp don't work at all. I did download the new Smart Guardian software from DFI, but I don't know if I can "trust" it, and also don't like the fact it does not show each cores temp.

Ideally, I want to get Speedfan or Core Temp working. Does anyone know how to do this? I know when I installed Speedfan 4.33, it actually caused my system to reboot, and I was not happy about that!

[Praz]

Don't know what to say mate. Speedfan and CoreTemp work fine here. TAT works on vey few boards other then Asus and Intel. And no software can be trusted.

Guys, which is the best ram to use with this board?
I was thinking about the Crucial Ballistix DDR2 PC8500 5-5-5-15.

If you have any other suggestions , I'd like to read them, thanks.

Read away. This thread has posts with just about every memory configuration you likely to think of.

By the way I just figure out that the power button on my Thermaltake Armor its indeed wierd and I think that is also a problem. What I mean is when I press the button it goes inside and when I press it again its hard to pop out... I need to use more pushing power and press it harder in order to get out...


Also when I just tap the power button and it does not even go in the computer starts right up

If this is so, disconnect the case switch from the board and use the onboard power button.

Hey guys, for anyone who thinks their system is stable as a rock can you do me the following favour? Loop 3DMark01 overnight with all title screens disabled and let me know what you come up with? Ever since my old NF2 based days I have always found that looping 3DMark01 with title screens disabled has always proved whether my system was stable or not. While everything else would pass with flying colours that would always freeze the system if it wasn't 100% stable. That is the problem I am having with this board. I am run OCCT for hours at a time, run Prime95 for 9+ hours without a single crash however looping 3Dmark01 will freeze the system anywhere from 30 mins to 5 hours. Completely random. Raising volts across the board does nothing to remedy this. I have not noticed a single issue or crash during day to day use, even after hours of gaming but it really urks me to know that that one app crashes when it should. To see if it was my video card at fault I looped 3DMark06 overnight with maxed settings to put the load onto my GPU instead of my cpu/ram and it too went for over 9 hours before I stopped it myself. This is really starting to bug me. If anyone could do this favour for me I would really appreciate it. See if your system really is stable as to me OCCT and Prime95 aren't the end all, be all. To put some strain on the video card I raised AA to 8x from within the 3DMark01 configuration. Thanks.

I have some initial results with this board, and am pretty impressed. I have just done basic configuration in BIOS, yet my Q6600 B3 processor seems 100% stable at 2972 MHz/330 FSB with temperatures in Speedfan 4.32 being almost 15C (50 C 50 C 48 C 49 C) lower than the same setup on my Asus P5W DH motherboard as reported in Speedfan 4.33.

Just to verify, the temperature reported in Speed fan 4.32 and 4.33 are both accurate? As a cross check, Smart Guardian shows these temps under load (Prime 95 on all 4 cores):

CPU = 54 C
PWM = 53 C
Chipset = 54 C

Once I get verification that these are accurate temperatures, I will turn up the speeds a bit

cantankerous: Sounds Like Power Supply issues. If you listen closely to your computer during 3dMark01, you'll hear a kind of screaching/whining coming from your Power supply. This is huge PWM current transients vibrating the coils in the transformer and filter coils in the supply. Basically long story short, you computer doesnt use current in nice easy steady streams. It demands current in hundred of thousands of pules per second. Depending on your power supplies filtering, this "ripple" voltage caused by the fluctuating current demands can cause instability due to the noise this fluctuation creates.

The regulation circuits on your Mobo uses current in pulses. If your power supply cant provide the current fast enough, or it is at a frequency that resonates (oscillates) the power supply output, then you'll get voltage fluctuations (oscilations) which are caused by current fluctuations which leads so instability.

One specification that is not mentioned anywhere in computer power supplies is transient response. This tells how fast current is delivered into a load. Switch-Mode power supplies are fantastic at delivering steady current at a steady voltage, but their transient response is the worse out of any power supply design. Computers demand current in split second pulses, if the power supply drops the voltage low enough for a millisecond during a surge in current, that equates to current that the CPU/memory/videocard regulation must compensate for. The regulation for the CPU/Memory/Video card is also switch-mode regulation (PWM whatever you wanna call it) which isnt known for fast transient response. SO you have a power supply being asked to deliver split second current with NO voltage drop (which isnt gonna happen with the relatively cheap power supplies used in computers) and also the regulation circuits must keep up with current demands for that split millisecond also. Say the voltage drops to an unacceptable level for 1 millisecond. during this millisecond, there have been hundreds of thousands of clock cycles in your computer and it only takes a few of these clock cycles to be corrupt enough to lock up your system.

Computer power supplies are dirt cheap compared to industrial units designed for perfect mission critical use. I've got a 75 watt 12 volt Switch mode power supply thats over half the size of my PCP&C 750 and costs $450. The specification sheet has 30 specs that deal with step timing, transient response rise and fall times and different load lines, regulation ratings, derating curves etc. This power supply has the regulation of a linear regulator but the transient response of an unregulated unit... No Matter how expensive your computer power supply is, it aint nothin special. Plus most computer geeks arent geeky enough to know that transient response is even important or even exists.

In all reality, I wouldnt worry about it tooo much. Your silverstone power supply is adequate for real world use. If it bugs you enough (which is understandable considering this is your hobby and your striving for perfection, which is good!) get something rated higher watts wise. Your most likly not drawing the limit of your current supply, but switch mode power supplies (and anything technological) work better when not loaded to near their max. If the supply is designed to have reasonable transient response and filtering into 1000 watts, it will perform even better in these specifications when loaded 40-50 percent. A good power supply will be able to provide THE NEEDED current twice as quick when loaded to 50% compared to 100% load. The transient response doesnt change, but since your only asking it to deliver half the current, it reaches this half current point in half the time (very simplified expanation though)

But back on topic, Whats the difference between the UT P35 T2R and the LT P35 T2R? is it just the heatpie and transpiper thingy? My XBX2 has given me an ulcer with all its problems and now wont run 4gigs of ram even at stock settings so Definitely looking at the DFI line.

Good thread though. this is still my favorite online forum for computer nerds!

@Praz: how come when i run SpeedFan, my system crashes?

Don't know. Maybe the version you are using?

Thanks a ton for the lengthy and detailed response. I am unsure what to make of it however as 99.9% of users use power supplies such as my Silverstone. I know there is nothing wrong with my unit whatsoever. Yes I have heard my psu whine, it has done that since day one and this has been brought up with Silverstone who believe or not has mentioned that this noise IS because of the VERY FAST transient response that their OP/DA line of psus supply. This noise is apparently only heard to those of more sensitive hearing than others due to high pitched the noise is when the unit is changing in transient response. I also know that my unit still has lots of room left. I have my system hooked up to an APC UPS which monitors how much load the UPS is under with my system in use. At full load my system is pulling 450w from the UPS but that is included 2 20" LCD displays which probably counts for about 90w when totalled together. I would say I am barely using half of what my psu is able to deliver at its 750w rating. If no one else has an answer on their experience of doing what I have done (if they even bother to try it at all) I may play around a bit more or just give up and live with my system being the way it is when looping 3DMARK01 since day to day use seems to be fine.

Thanks again.

Using this tutorial, I flashed my bios to 1019.
http://csd.dficlub.org/forum/showthread.php?t=1136

But now when I turn on my computer, post will hang for a few minutes before loading windows. It's a nightmare to reboot the os or gain access to the bios.

I searched this thread for any answers but wasn't able to find any help. Does anyone have any ideas?

BTW the LED error code usually got stuck on 75 and 52. 75 seemed to be the sticking point for the most part.

Are you using that abortion Vista?

Why is it People "Refuse" to take good advice? Once again there is still great worth in that Out dated (Viable) Floppy Drive that people tend to bash these days because its been around for ever but Proven and Reliable, yet people refuse to spend $6.00 on a Floppy Drive and keep it simple!

[x6700]

No I'm not using Vista, why would you even ask? What does the OS have to do with posting?

BTW way to go on the double post. Is the edit button broken?

[n00bstorm]

I was able to fix the problem and now my PC seems to boot right up... so I connected all the HD well most of them... and started to transfer files from one to another and the PC keep crashing randomly for no reason? Ill let it idle for a while and see if it happens again but what can be the cause of that? THanks

[Brother Esau]

No.......I did it just for you because we told you the other night to keep it simple and buy a Floppy Drive as to avoid complications with Flashing Bios.

BTW....Way to go....I told you so

Brother Esau any new on the dfi x38?
i see you guys havin so much fun with this one i wanna join in with the x38

[extol1337]

im ortho'ing right now at 325x9 1.3v on my E6700 on the P35 T2R board strap @ 266/667.

stock cooling right now till i save up for my WC stuff.

temps are 59C load right now in my extremely hot room.

lets see if my chip sucks or not haha.

I don't know man we have been told 12-19th for release date thats what I hear any way.

When I say we I mean Public announcement not me directly Praz or Raja would know more

[n00bstorm]

Now even when I'm just surfing the net or listening to music it just randomly restarts after showing a blue screen with some kind of letters all over it for less then a sec. Even when I try to install a game or something keeps saying windows error etc...

ok here goes.
try raising the v-dimm to manufacturers spec. probably 2.2v.
raise n/core to 1.5v set memory timings to auto.
use 333/667 strap for 1:1 timing
raise cpu core to 1.35 (just for testing) unless you are already higher.
f10 and reboot, try these settings to get you running. (others @ auto)

like others have said, this board needs some knowledge to tweak properly, take it slow and read the entire thread. the ENTIRE thread. there is more than enough info here to get you up and stable.

I gotta go to work now. hopefully you can get it going good today.

btw. the reason i suggested what i did is it sounds like a ram issue to me.

[n00bstorm]

I'm sure it is but thanks for your replay ill set those settings and see if is stable... then I'll indeed look over the whole topic as I would like to also overclock my Q6600 a little! Thanks again!

By the way just a quick question should I keep my Corsairs Dominators 1066 or Crucial Balistixs 800? THanks!

[Praz]

You know me. The only release date I'll quote for anything is when the item is actually available to the public. Too many variables in this industry to to be stating future release dates.

@n00bstorm

Try both sets and keep what works best.

[Brother Esau]

OK........Listen man create a signature of you're components please so we know what you have in order to help you better.

Do me a favor also list what version of Windows you are using too.
