What do you mean buggered??? You broke it and how? Or just a problem with defective board?

Hello,

I have a qestion about the voltage settings:

SB 1.05V Voltage
SB Core/CPU PLL Voltage
NB Core Voltage
CPU VTT Voltage

what are the highest "safe" settings for these voltages?

I try to get 500MHz FSB on my DFI P35 T2R but when I dont increase these settings my system only posts C1 on the diagnostic LED. When I increase the settings my system starts Win but is not Orthos stable.

^ You only need to play with NB Core Voltage and CPU VTT Voltage, 1.53-1.57v NB Core and 1.4-1.6v CPU VTT is the sweet spot for most.

Did you guys noticed whistling sound this mobo makes when you set CPU VTT Voltage to something like 1.5-1.6v? It's very annoying and loud, I can't seem to find where it's coming from.

[C-N]

I had troubles running ram with EDT and EA set to FAST. If you run into stability problems, then it is an idea to try these set at NORMAL.

Yes but you will take a big hit in memory bandwidth, I would recommend trying to tweak around theses functions on fast.

Unfortunately my DFI is buggered Waiting patiently for a replacement.

Oh no what happened

Unfortunately Yes. The sound seems to be memory related, getting loud everytime it's stressed. On mine the whistling was most noticeable doing something like a blend or memtest.

Yes but you will take a big hit in memory bandwidth, I would recommend trying to tweak around theses functions on fast.

Yes, v.true. However, I did find that blend stable was very difficult to achieve on fast. Especially at cas 4. Just my experience

What do you mean buggered??? You broke it and how? Or just a problem with defective board?

Oh no what happened

Board just started playing up.

First indications were memory problems, slow pi runs, memtest failure etc. Thought the board had killed my ram.

Took it back to the shop. They did a great job, spending a good hour or so testing everything.

Tested my Gskills in a DFI 965 and they're just fine , but the board's a dud

Just thinking aloud here. need.for.mhz mentioned the whistling sound at 1.5-1.6vtt. Hope this isn't related to my boards failure.

The quads need 1.5v+ to run stable. I almost corrupted my OS trying to run lower than that.

Makes me wonder whether DFi actually tested quads out or not? Given the late release they certainly had time

Hopefully better luck on the next one. Took two IP35 pro's before I got a good one

This is what I have to contend with in the meantime.



I call this run "who ate all the PI". (forgive me)

The only 2 boards that have ever gone bad on me that I really didn't think were owner induced were both DFI's.

The IP35 Pro has made me aware of Abit again & because of it I will be considering anything they release from now on. I love my IP35 Pro imo an amazing board for the money.

I am impressed with the build quality on the DFI P35 & hope for my sake you just got a duff board & we are not starting to see a trend here like the ICFX & 680i with there C1 & 88 errors.

Edit: Its funny you mention your P4 I just pulled my old DFI 875P-T out of the loft yesterday ok its socket 775 but ill PI race you if you like LOL.

Guys, sorry about the double post, but I was wondering if you need to do anything special to get into the ICH9R RAID menu. I am familiar with the ICH9 with the IP35 Pro and figured the RAID setup would be the same. However, I am unable to get the CTL + I menu to come up.

I have a 250G on SATA0 (or 1) - BIOS is setup for RAID and Jmicron as Native IDE. I can see my drive comes up as port 00 - correctly identifying my drive, however, I am unable to configure the drive in the RAID BIOS and/or get the CTL + I message.

Typically I'll install one drive on the RAID controller as JBOD, thus I can setup my real RAID later w/ an image.

I was able to install the OS and it properly identified the RAID driver as being used. When I navigate to the Matrix RAID in the OS, it launches properly but flags my drive as a NON-RAID disk????

Maybe this ICH9 iteration is a newer firmware and does not allow creation of JBOD, or assumes it if only 1 drive is connected w/RAID enabled?

[Praz]

Makes me wonder whether DFi actually tested quads out or not? Given the late release they certainly had time

Although I did not inquire as to the specifics I do know that Quads were tested on this board at DFI.

EDT and EA set to Normal can result in as much as a 8-10ns loss in latency time depending on other settings.

[Lestat]

the whistling is the pwm/coil packs
it has nothing to do with memory, it has everything to do with stressing the board.
if its more predominant when running mem benches then that indicates that the coil around the ram area would be at fault, possibly. but not definately.

this is the same 'ol squeeling we been dealing with for a long time its nothing different.

but its not good, its not BAD per say, but not good.

some companies are doing RMA's for squealing boards.

Please tell me this is not a faint high pitched frequency sound almost like a dog whistle frequency sound? Because if its like that and this $300.00 board does the same thing that every motherboard as of late that I have owned does then its just something involved with Intel boards and quite honestly its been driving me nuts and if that the case I swear I will get rid of everything Intel related and never by their platforms again! I mean this is bull sh@t it seems as if everything the past year built from Intel motherboard related outside of the server end of thing is just crap and fails miserably and has a life expectancy of only a couple of months and its back to square one again.

You know I ran my D.F.I Expert Overclocked 24/7 for a year strait with 3 different cpu's and it never once failed and broke down and I still have it and could pull it from the shelf and P.U right where I left off and it still runs like a raped ape on steroids and is server class reliable and solid. I am really just starting to think that anything Intel related is designed to fail because as it appears we have all gone through half a dozen boards just trying to get back what we had with our AMD systems


This will make Intel Motherboard #6 for me in only 4 months

[cantankerous]

Why do I always hear of issues AFTER I order the board? I asked about squealing weeks back as I was worried of this turning into another P965 'Dark' fiasco where that board whined and whistled like no tomorrow. I heard nothing on such a noise so I placed the order last week. Now I am hearing the board may actually squeal under load plus a board that went belly up in only a couple weeks? I know it is random and could happen to anyone but this is exactly the kinds of problems that starting surfacing on previous DFI releases in the past year. Not good at all. I sure hope my board comes out alright, and I do hope all of your boards continue to work fine if they are not yet acting up and for those whos board is borked get a good, working replacement.

[Brother Esau]

I am with you on this one cantankerous! I am sorry but like I said originally when I was still on my AMD system and even when running the new Intel current to date AMD is a SUPERIOR Platform and I am even more thoroughly convinced of my original statement and stance on the matter considering how much crap I as well as everyone else has endured just to run Intel's new processors and I don't are what anyone say's this is just as much fault as Intel's as the motherboard manufactures! Think about it if you're name was featured on all of this equipment would it not stand to reason that YOU would provide a working solution to ensure that you're name was not tarnished? Obviously Intel does not care and is only about feeding the machine with more and on that pretense alone.

[Praz]

Most any board, server class or otherwise, has the probability of the above mentioned squeal. The reason we as enthusiasts see this so much is because of how hard we push the hardware and the options available that allow this push. The only real solution is higher grade and/or additional components. It's doubtful the market would bear the price point that would be required for the components that would have to be used. The second solution of additional components would be less of a cost issue but the needed real estate on the board doesn't exist.

[Brother Esau]

Good morning, John nice to see you Like I said its Intel's fault and we are not asking these motherboards to do anything that a server stress environment does not create for any given hardware! Excuse me I do not push my stuff to out of control voltages like allot do in theory and in practice I find the max and back off 200-300 mhz Dependant upon how much voltage was needed to find my ceiling.
So in actual fact whats the problem on my end? I am very level headed when it comes to O.C and not unrealistic in the sense that I don't run electric chair voltage through my equipment and expect it to last and not to fail!

[Praz]

Nice to see you about also.

The conditions you are indicating you will run your system at I'd be surprised if you get the squealing. I've yet to get this one to squeal. But then I never saw the problem with the 965-S or QuadGT either. Now my 8800GTX on the other hand sounds like a cat fight when I push it.

[RLM]

That's my ignorance showing Letsat. Possibly adding 2 and 2 and getting 3.

Had the same squeal on my Quad GT. It came from a coil just under the memory slots. However the machine ran stable as a rock and gave me months of 3d rendering without a hitch.

On the commandos I seem to remember people were coating the coils in silicone sealant to prevent the noise.

Although I did not inquire as to the specifics I do know that Quads were tested on this board at DFI.

I read a thread the other day, where a guy had written to DFI about problems with his 8500 memory. Allegedly DFI replied to him saying that they hadn't tested 8500 sticks with the board.

It was this response in part that fueled my speculation.

If they have been tested with Quads, and I hope run of the mill quads, then that's reassuring.

The last couple of weeks, along with running my own copious tests, I've spent a lot of time trawling forums, including babelfished Japananese, German and Italian ones. It's been difficult to find any decent info for running a Q6600.

What's needed or wouldn't hurt is some sort of guildelines. For instance as I say with my quad findings, too little voltage in the VTT seems to be just as detrimental as maybe too much. I want details Or is that maybe too much too ask.

EDT and EA set to Normal can result in as much as a 8-10ns loss in latency time depending on other settings.

Did a lot of tests with EA and EDT set to both Fast and Normal. Yes Normal is quite a bit slower. However on both my Geils and Gskill I could not run them at 1000+ cas 4 with fast settings, stably. That was irrespective of performance levels, trfc, clk, voltage or loosening other timings.

Not knocking DFI for this, I just put it patiently down to early bios.

Not trying to sew the bad seed here. I've had some decent results our of the DFI, and optimistically I'm hoping that my replacement board will be all good. Just hoping I don't have to wait too long

I am very level headed when it comes to O.C and not unrealistic in the sense that I don't run electric chair voltage through my equipment and expect it to last and not to fail!

A wise choice for a 24/7 system, good voltages keep things alive. One of the worst things a person can do is run a system continuously on, or near benching voltages 24/7 and expect things to last, ram is usually the quickest thing to fail.

Since I didn't ask details this is just a guess on my part. With the quadcore results that have been posted so for compared to the tone of the conversation I am under the impression the testing has been done with average processors and no sub-zero cooling. But once again this is just my opinion.

I have found the same as you concerning voltages. Too much is as bad as too little and they are to an extent interdependent on each other. People that push everything full throttle and then back the settings down for 24/7 are going to be in for a rough ride. Finesse is what this board responds to.

I am not so sure its an Intel deal... I have had the annoying high pitch squeal when heavily overclocking on several motherboards, including my AMD based DFI lp ut nf4 sli-d.

Now for the good news, I have a DFI LP UT P35-T2R (ugh, too many letters) and it does not appear to squeal under heavy OC load.

'least I'm enjoyin' the ride !

[Grinch]

I have noticed some slight squeling as well...only when I am priming small FFT's...any other time it is silent...

[ACE76]

Overclocking can be a little hit & miss sometimes & hopefully a bit more play time will get you going.

The Abit suffers wicked vdroop when you start pushing a quad perhaps you just need to juice up the CPU or maybe do the vdroop mod although I haven't done it on mine & I can still pull 3.8 prime stable for hours.

Anyway if you have got a DFI LP P35 on the way I cant see you being too bothered about playing with the Abit & quad, as someone that cant help my self tinkering about with things I cant help but keep buying DFI's I can tell you now if you are anything like me you are going to love the DFI's BIOS settings.

I do love to see a bit of Phase action good luck & don't be shy to show us what you can do with it

CN

The phase is coming in tomorrow....but I'm going away until next Tuesday so I will have to wait to play with it until then ;(

I do have the DFI board up and running...OCing it has been fun so far....no issues whatsoever...I love the fact that droop is under control with this board unlike the Abit board...I have both the Thermalright Ultra 10 Extreme and Tuniq Tower 120 with a 95cfm fan...I will test/compare both coolers tonight because I think my Thermalright is not performing the way it should be.

[Brother Esau]

I am going to install my Tuniq Tower 120 on the D.F.I and more than likely sell this CoolIT Eliminator which is just a awesome cooler I got a really good one so I was lucky!

last night I run 2 hours of Prime @ 3.8GHz DDR1190 on air @ 1.52vcore @ 2.27vdimm so I think you are going to have a lot of fun on phase

The voltage stability is outstanding on this board the only problem is now I have experienced this level of accuracy I have been spoiled & am going to expect it from now on.

I have both the Thermalright Ultra 120 Extreme & the TT 120 for me the Thermalright wins bye a few degrees as long as you use 2 high cfm fans push pull otherwise they are about the same with just one high cfm fan each.

I have lapped both my TT & Ultra & it helped them both shave a few degrees off my temps with various CPU's. My Ultra 120 was very concave & took a lot of lapping to get flat, its not easy with such a small base to hold onto either. BTW there is nice copper under the silver when you start lapping.

I am going to build up my decent watercooling later next week when I get hold of a D-Tek CPU block & see if I can push my Q6600 a little more just for fun. If my Q6600 will go a bit more I may just lap it too

[Solarfall]

you guys that own D.F.I LanParty UT P35-T2R board .. is it true that this board has no or almost no Vdroop ????
