The settings are applied when you boot Windows, and should therefore provide a much safer method than the motherboard's C'n'Q operation. Hopefully it will fill all your needs...
A little late now don't ya think............... I've tried Rightmark on several boxes with little success........
I wouldn't know...............Quote:

thx perc,
Ok. So far, so good. Building a new system using expert board with my old 3200 and OCZ rev 2 TCC5, running 10x250 at stock volts. Had no problems with initail start up. Haven't yet had a chance to see if I can get a higher overclock, still installing all my apps. This chip was 3d stable at 2.8, and prime stable at 2.65. Using shipping bios. Temps do seem way low, though. My case temp is 26C and SG is showing idle at 22C, lolQuote:

How the latter plays with the cuts we have seen on some but not all Experts I'd say is a good question/
No, I don't remember where exactly that posting was. But "expert" and 'revision" as search terms might do it quickly.
What board revisions are there so far?
I just received my Expert and i think...if i'm reading the right spot at least my revision is AAO? :S
Well once the board goes up in smoke and takes a 170 with it, it's a little late........ Read the rest of the thread.Quote:

why? id just like to know how many people with dead boards there are, we all know that most boards work totally fine, but nobody knows how many boards have died already. 12? 25? 40?Quote:

its not that theres a fixed percentage of boards that goes belly up, at least thats not what it looks like if you ask me.
Instead of letting this thread slide off topic or get conjested with alot of "I haven't had a problem" post, how 'bout someone just starting a poll thread we can monitor.......:)Quote:

I wonder if DFI engineers have been able to reproduce this issue yet on the Expert? At this point I guess we aren't really sure what excatly the issue even is. Can anyone at X possibly get some sort of interim statement from Oscar Wu? Even a "don't do this" or "set this to xxx" while they are investigating would go a long way to help.
Yea so I am new here, but not to computers....
I just bought an Expert board before hearing about this issue with it killing cpu's, so I want to know what to do.
I won't be able to complete my build anyways until Christmas day, or the day after anyways, but what should I do: A). Use the board and not overclock until problem is solved, or B). RMA the board and get the Regular Lanparty UT nF4 SLI-DR mobo?
Is the problem coming when people try to overclock their boards? Or does it just happen the first time you start your PC? I read the thread but people had different statements about that.
Also, is the new "Official Bios" out yet, and will that even fix the problem?
Thanks,
-Mitchell

the chance that this happens to you as well is not that high, but its there...
Thanks for the bios file pcdoc1. I flashed my mobo with it and my rig would not boot. Heh! I was pi$$$ed! I pushed the power button & reset unplugged the PSU, cleared the CMOS and repeat about 4 times still nothing...I the removed the CMOS battery and re-installed it and tried again and BLAmmmoo! It booted...wheeew!:eek:
I still can't get much of an OC I have yet to get my Corsair 2gig to its rated 250fsb. I had some sucsess by lowering the LTD to 4x & setting the fsb to 240 but the mem bandwidth suked.
I guess we are just gonna have to wait it out. i do remeber the SLI-DR having teething problems for the first month. All that was solved when Oskar released a bios for it. I guess its the same situation here.
Patience for an OC'er is rare....heh!
so a cmos reset didnt help but taking out the cmos batter did?
lol... but you arent supposed to take out the cmos battery anymore because it might kill the board and cpu... weird...
how come a normal cmos reset didnt help but removing the cmos battery does?
Well i have raised vcore a bit, just in case, but am worried about how high i can go, so i won't be doing much overclocking right now.Quote:

then dfi will have tons of boards rmaed to them because the bios was updated or some setting changed and the system crashed and wont boot again.
but the bios couldnt be resetted because its too danerous to remove the bios battery :D
and what will dfi do with those boards?
remove the battery to reset cmos i guess :D
this is all very confusing :D

I would love to buy an Expert, or better put ask for it for Christmas, but hate to risk my cpu and ram. Being in college doesnt leave room for the hardware to take all my stuff in one big boooom.
Its one thing if I kill it myself while overclocking, its anything for it to send up enough smoke to signal the Cherokee Reservation down the road. Obviously the board isnt smoking literally....just a funny pun for a not so funny situation.

Might be that this only happens when changing BIOS settings. If you run at stock your prolly alright, but who's gonna do that on an Expert ;)
@Saaya, I agree. If you need to remove the battery and thats what DFI is claiming is the source of problem its a little scary.
Very confusing indeed! DFI will NOT honor any warranty if you replace battery - funny thing is that the boards I received from RMA DFI must have had the battery replaced - cause I had the voltage problem with those boards - rofl. Bunch of dodosQuote:

Also is AMD going to approve warranty of a fried chip caused by this faulty motherboard?

if you tell amd the board most likely was faulty and killed the cpu they might point you to dfi...

I sure would sleep better though if DFI would do something to put this issue to rest..... I would think they'd be somewhat in a hurry to get this behind them as I saw a post in AT's forum tonight pointing to this thread... Not exactly good press! :cool:

Funny thing - considering that taking out cmos battery is IMPOV the industry standard of clearing cmos - (and required for previous NF4 boards...), now it's a nono - guess soon we'll see a new offical bios that will take care of that, yet the DFI p[eep who sent me 2 tested RMA boads - also removed the batteries - cause I had the bug from the first time I booted the boards- so it only took me 5 mins to find the bug - not days...

I am thinking v-code=v-core, i am using the expert with the 4400+ X2 & yet to face any issues. I will have to do a lot of cold booting & shut downs & see.
I cant see how its user error in my case , hell it didnt even make it to bios before killing the cpu , nothing at all on the screen before it died, mine died instantainious, and i know it was not my fault. But after flashing bios that board is fine ?
waiting to see your result on the eXpert Naser.
btw, Naser, your page's one of my fav. source and reviews before i bought any hardwares while i was in abu dhabi. :)
I am glad we could be of help.Quote:

That said, I have no idea why anyone takes the battery out to clear the cmos anyways. I've never done that in my life....and I've cleared the cmos on boards like 20,000 times. Obviously, if the battery is dead, you got to remove it. But, if that's not the case, why are people taking out the battery? Powering down the board and using the jumper should be enough.
I never used the battery either, jumper always works. As for me I will try to switch out batteries just to see what the problem is but regardless board is going to RMA and im switching it with the a8n32 sli dlx. I am not too impressed with this board.
@ Crash
Asus Boards with NF4 are not free of bugs either. U'll have problems with timings 2-2-2-5-1T over 200MHz FSB for RAM - tested on TCCD and BH-5 like Geil Ultra-X 2x512MB (old and new) and Patriot XBLK 2x512MB and 2x1GB and few other brands.
mike, on my dfi nf4 ultra-d i could somestimes only get the board to boot again if i set the jumpers to reset and waited for 30mins. when i didnt want to wait i shut down the psu, powered it on again, shut it down again, waited for the leds to go out, powered it on again etc. after 10seconds of this the cmos was fresh and fine again...
so im not surprised there are people who have problems resetting cmos, seems the design is the same and it takes a while before cmos is reset properly.
after hearing about all this wouldnt recommend anybody to do what i did with my dfi nf4 ultra-d with their cf or expert boards though!
I had NEVER had to take out a battery until I got this Ultra-D( I heard other folks have, but I never did AFAIK), TBO I still don't know why I had to take it out, but I did.Quote:

Pretty tough thing to deal with IF there is an issue with the battery.
I'm gonna keep digging, but the word has been put out there.
BTW IF you are waiting for an OFFICIAL statement from DFI about something like that you may be waiting a LONG time...
Then you can wait some more.:D
There is a SUPPOSED statement about the RDX200 and battery removal at post 185.
I am aware that the RDx200 is not the Expert, but even still, that BS...
there is indeed a statement from dfi engineers concerning the RDX200 CF-DRQuote:

Thanks for the input.
BTW WHY would they state to MFM that it MIGHT be the battery, when his WAS ( notice how I said WAS) an Expert that killed an FX/ 2gb Patriot ram..
not to mention the Expert died along side it.
If it were my board I'd have put a screwdriver through it like the POS LP NF2 board that killed my Barton.
I'd have to agree with you. If I read those tips, I'd have removed the battery too. These DFI boards have certainly introduced a whole lot of wierd $hit to the equation.Quote:

I am not a fan of Asus, cuz the worst board I ever owned ( stability wise) was an Asus.
They also tend to be very slow with updates ( even though they need them), and they don't give you sqaut for voltage options.....
I was hoping their MVP board would be better, but it's still an Asus with very limited voltage options..
I use my Ultra-D for my HTPC, cuz I need to OC like crazy if i wanna run heavy settings using FFDSHOW ( cpu eater)...
I am an AMD fan, always have been... the P4's rule FFDSHOW, so AMD chips need to be rockin' to make up the difference..
I'd hate to have to buy a P4 to do well in my htpc, I've only owned 1 Pentium chip, the original 233 mhz that i built at Computer school...
Which i fairly quickly got rid of for a 400 Mhz AMD K6-2 :D
Sorry for the OT...
Now back to our scheduled programming...

Boards that do not have them in series can still hold their bios settings with the reset jumper set to clear, with the jumper removed, OR with it pulled to ground.
A full reset would be performed by UNPLUGGING THE PSU (from the motherboard), removing the CMOS battery, AND placing the jumper in the clear/ground position to absolutely drain all capacitors and circuits of any power left in the board while the PSU is off.. This will take a minimum of 30 seconds. Unplugging the power supply is a crucial step with this board possibly seeing as removing the battery with the psu connected can cause problems....
yeap done that plenty of times already and didn't kill anythingQuote:

Back on topic. If its true that DFI are playing games with regards to this whole CMOS battery thing, then they ought to to be reported to the BBA. This is BS. What kind of crap is that? I will not mince words here. If thats what they told mike (he is one heck of a patient dude!), it is absolutely unacceptable! This is shocking stuff.
On this whole CMOS Clearing issue with the NF4 Ultra D/SLI DR, I believe the very mention of the fact that the PSU Cable has to be unplugged says something about how the CMOS is discharged (none-too flattering if I may add).
Where the heck do the capacitors/CMOS discharge to???
Logically, all discharging is done via GND (Ground). Now, this would imply the Mobo GND (both digital and analog) are FLOATING! Now, a FLOATING GND by itself is not a problem and is quite often used without issues, discharging is always via the true GND. Unless they are single point tagged to the supply GND (which is the true GND going to your building's GND pit), its not good for noise performance and other conditions. The charge should dissipate in a matter of milli/micro-seconds, given that there are no huge capacitors on the CMOS.
Now, I have personally waited for > 30 min in one case to discharge the CMOS. To me, this points to a horrible design, where charge has to be dissipated by AIR, since the power chord is unplugged. Since then, I left the Power chord on, but turned off the supply (surge protector), so my GND pin is still connected to the true GND. It takes about 5-10 min.
Discharging via a "bleeder" resistor with small caps should take micro-seconds or less! I don't know what the deal is with their design.
if i got it right what killed the boards, according to dfi, was that people removed the battery and did NOT set the jumper to reset. does somebody understand how this could kill the board?Quote:

In brief, this alone cannot and should not kill a board. It simply doesn't make sense. I cannot see how this could kill a board. A CMOS battery alone does nothing, even if its being used as a unipolar device (-tve as GND), I don't see how removing the CMOS battery could kill anything. :confused:Quote:

There has to be some mechanism of actual discharging. So, what happens to the charged cap? Its still live and can hold charge for several years (believe me, I've been shocked like hell when I had an old Television Cap discharge on me!). Why hold the charge when it can be bled off? I have NEVER had this problem with my ASUS A8V. Reset was almost instantaneous. No need to jump through hoops.Quote:

10min is still pretty long if you ask me...
my guess is it may be a wiring/pcb fault.. somewhat like boards that do not have a choke and capacitor near the 4-pin P4 connector or 6/8pin that some have now.
Can give a thumbs up to split rails for causing problems there.
Why do you think its the split rails?
Also, what do the chokes do? Are the mini-isolation transformers?
