Ditch this board while you can.......

Also there is some juicy information about to come out about the DFI boards....i cant say anything just yet until i get the authors permission....but OH MY GOD are DFI users going to cry and jump ship.

I've got three different DFI boards, both of the NF4 have been running 24/7 for several months overclocked with high voltages. I have used the 5v jumper on several occasions testing OCC VX and other UTT. I've yet to have any issues with the boards,....NONE !

topboy, I think you like to stir things up :D

I'm sorry that you had problems with your board

sorry if you think im stiring things up Major.......It seems your experaince is a good 1.

All im saying is that DFI have admitted there is a problem with the board.

Stick you head in the sand Major if you wish.....but i feel it only right to let other users know what DFI have told me.....and what technical information is going to be released very soon regarding the tricks that DFI are playing with its users.

Just sit back Major and watch. The information will be out soon, and will upset SO SO many people.

He has had 4kits of VX and 2 kits of twinmos BH5...all have had one module killed. This is just one guy....i have story's from many more.

Now i know you all love this board...i do to, issue is i don't like it killing memory, if it hasn't killed yours and you are on the 5v line, you ain't used it long enough yet....thats how I feel about the situation at the mo and im working VERYhard to help solve this problem.

All those people who are saying it has to be user error, go read on multiple forums to see what people are having issues, see how they set their rigs up and you wuill see they are just as thorough as you are and as I am.

Im going to say this again, come off the 5v line, tweak your 3.3v rail and enjoy your memory and your motherboard.

Hipro seems to think his maximizer works well and we have found the booster does also...maybe this could be another answer.

Now i know most will blame my lack of knowledge or something but here is what has happend to me

two DFI SLI-D boards (on my third will be here monday)
two OCZ PC3200 VX kits(my new PC4000 VX arrived from OCZ overnight Fedex thanks OCZ!)

Both Boards ran for roughly 3 weeks and then died all had the jumper set to the 5v line. Each memory kit had one stick die.

Both Boards the DIMM closest to the CPU (orange) was dead. the boards would run fine as long as i only ran one stick of ram in slot 3&4.

My point is i've had 2 sets of ram and 2 DFI boards and with the 5v jumper selected, all have killed DIMM 1 and the stick of ram in it.

For the record i ram my ram@ 3.4v 2-2-2-5 1T 250

To be safe i am just going to use the 3.3 line from now on, hopefully i will be able to run 2-2-2-6 250@3.2 volts with my PC4000 VX....

Out of all these posts Bigtoe seems to "just get it" and realize something just isn't right about this situation.

Thank you DGeNeRaT3

I was starting to think i was banging my head against a wall.

When will people wake up and realise that there is a serious problem with these boards and the 5 volt jumper.

Move boards or move jumpers people...

Zero problems here, just to add my personal experience, I've been running on the 5v jump since my ultra-d was first installed, I moved to 5v before ever powering up the board for the first time so that I wouldn't have to screw with changing later on.

I bought this board when zzf got their first order in around the end of Febuary I believe it was so its among the first batch and it runs 24/7 day in day out, not intermitent, I use this computer largely for doing cad design work all day long, doesn't miss a beat at all.

I don't run high vdimm, only 2.8vdimm, since it has run perfect for a long time now on the 5v rail at 2.8vdimm I don't see a reason to change it.

Anyways, I agree that there must be some boards out there with problems but I know for a fact my board has at the very least lasted more than 3 months of 24/7 operation overclocked with zero hardware related issues to date and continues to work flawlessly.

So I don't think its true by any means to say there is a definitive problem with "all" boards since there are still a large number of us that have had zero problems with 24/7 operation even on the 5v rail.

This is with a Ultra-d, 3700sd 10.5x260, XP120, OCZ 2x1024 Platinum 3200, Antec Neo480, xfx6600gt, 24/7 operation.

Before I got the 3700sd I had a 3500 claw that I was running 11x240 which also was left running 24/7.

I'm sure there are allot of people paranoid after browsing this thread which shouldn't be, this is not an issue with everyone using a dfi nf4 board running memory off the 5v rail.

Err why are you running the 5 volt jumper when you run your ram at 2.8 volts.

I agree there maybe boards out there that are all ok.....BUT the fact remains that DFI admit that running this board on 5 volts can cause ram to die and chipsets to fail

So why dont we run on the 3.3 volt jumper until they fix it....i cant see the harm in this....makes perfect sense to me....and when/if DFI fix this....then we can all jump back onto the 5 volt jumper

I've had no issues with my board as well at 3.5v for three months.

But I do feel that's it's sound advice to move back to the 3.3v line (if possible with your RAM)

honestly topboy, you seem almost "gleeful" that there is a problem.

Umm well because my system has been running flawlessly, why would I want to change something. :confused:

There wasn't any info regarding the 3.3 vs 5v rail issues when I originally setup my ultra-d, before it was screwed to the mb tray I switched it to the 5v rail.

If in the future I do run into an issue I will definitely post something about it but going on 4 months strong I just don't see it happening at this point.

Very true - however it also opens up liability for the company. :nono:

As far as I can see - the issue affects a small percentage of the "enthusiast" market that the board is targeted at.

I agree

Im also yet to see ANY solid comfirmation from DFI that there is a problem.

I say it AGAIN and AGAIN, if this board is voltage spiking enough to kill Ram it will blow the on die controller before the Ram, this (contray to DFI board killing Ram) has been proven with the early Shuttle boards.

Im getting increasly p!ssed off with ppl bleating about boards killing Ram with NO evidence.

Lets ALL just wait until some serious testing has been done by ppl that ACTUALY know what thier talikng about :stick:

its not the boards imo....people are just mad because they actually had something die (which is half expected when you overclock) and they are looking for somewhere to point their finger. the dfi nf4 is probly one of the most popular boards so why not blame it on that? lol ill almost guarantee the UTT is the problem. its new and dies a lot. heck, twinmos stopped warrantying any UTT based product they sold. if that doesnt tell you something then i dont know what will....yes you can test it to 5v at -85c and it will survive for under a min without problems. but running 3.5v at 40c for days on end is where the product fails. i agree with jiff, it would kill the memory controllers if there was a voltage spike. ive yet to see a case where the memory controller was killed along with the ram....

Switch it back to the 3.2 IMMEDIATELY. You've been lucky not to have any issues yet, but you're gonna run into some in the future with that much of a discrepancy between your 2.8V and the 5v rail. IIRC, the bigger the difference between the two voltages, the higher chance that a particular IC which is fed by the 5v rail is going to fail.

:confused: Running 3,72 Vdimm from 5-V-rail for more than 3 month, no problem at all.

Don't blame DFI generally ppl - they replaced my first DOA Ultra-D with a SLI-D without extra costs!!!

Fine customer care.

HCC, 3.72 is MUCH safer to run than 2.8:
5V-3.72V = 1.28V which is better than 5V-2.8V = 2.2V ;)

Yeah I relealize there is more heat generated for running it this way but I'm comfortable with it running this way, I also have a 80mm fan cooling the upper mosfet on the corner of the board, the xp120 seems to do a decent job around the socket.

I guess what I'm trying to say is that I'm going to just ride this pony till she falls for the sake of research, takin one for the team, at least then I can positively say my ultra-d only lasted xx months at 2.8vdimm on the 5v rail before it kicked.

If it does fail I won't hesitate to buy another one but I will be sure to leave it on the 3.3v rail next time, that is if I do in fact have problems in the future.

If I don't have any problems well then we'll all have a better idea of durability of these boards stepping down the vdimm way down under the 5v rail.

Hey, NP, I totally understand. You're just lucky you got a board that worked for as long as it did. Me? I'm on my 6th board :p:

exactly. its a linear design and the extra power is just dumped into the mosfet as heat. thats bad when running something too low. you are taking 5.1v (around that) adn changing it to whatever you set it to. the lower you set the voltage, the more heat and the more room for error. anything above 3.3v is pretty good, but should always have a fan blowing on the top rigth corner of the board when using the 5v rail jumper no matter what...

;) Yep - now I remember Oskar told us some time ago to use not the 5-V-rail when the Vdimm is below 3,2......

BTW - where is the point using 5-V-rail with only 2,8??? :confused:

exactly...and the 3.3v rail would be more stable in that case

No point in it anymore but originally I thought I was going to be pumping allot more voltage to the memory than I ended up using. In the end the memory just didn't respond very well to higher vdimm so there I was, been on the 5v rail since.

Since there where little to no information on the 2gb kit of ocz platinum memory I figured I'd have the extra juice available from the getgo.

;) So Stephen is right - if You're satified with the 2,8 save the board's life and switch back to the 3.3-V-rail......

Just remember this, even IF...i'm just saying IF.... DFI found the board is to blame for all those dead rams out there, do you really think they'll admit it then announce and release the bad news to the public that they'd screwed up?!?! :lol: think about the consequences if they're stupid enough to do that....can you even imagine how many people going to start requesting coverage for all those dead rams out there?!?!

I'll be using the 5V line tomorrow. For a refreshing newbie taste to this post, what should I set the voltage to before switching the jumper :wasntme:

Nice to see you again HCC, haven't seen you for a while :)
