DFI NF4 Cold boot issue?

I have a DFI NF4 Ultra-D.

I've had my mobo over a year running fine no problem with my Old Opty 148. Recently I installed a dual core opty 170 and am now having boot problems.
The problem is the computer will not turn on when pressing the power button. In the morning, afternoon, night, even after having the computer on all day, then turning it off and on again (nothing).
The only thing I can do to fix it is turn the PSU on and off about a half dozen to a dozen times.
I've searched the cold boot problems, but they all seem different. When I put my single core CPU back in, it works.
I tried a new PSU, it worked fine initially (off/on) until one time I turned the computer off, then on again, and it didn't fire up. This sat in my mind that it couldn't be a PSU issue.
The Standby LED is always on, the Dram LED is only on when the computer starts. The DRAM LED does come on after switching the psu off and on a bunch of times. When I see the DRAM LED lit, that's when it boots.

Anyone got a fix? This board has been fine for a year, now since switching to dual core its having this problem. I've tried other Bios, nothing. I would think a Fortron 500w would be enough to power a dual core, 6800gs, (1) optical drive, and 2 HDD's in raid.

Thanks for the help everyone.
 
i've built a number of ultras--some were super PITA about psu's . just because you tried a new psu with enough amps/watts isn't a sure thing with the dfi's.


i also had one that the bios chip died in--just before the bios chip conked out the mb was having a hard time starting up .

you might try removing/moving the ram chips around --you may have a bad stick of ram--or a bad ram slot --or low power to the ram thats causing the issue . a small batch of these mb's had very low volts/amps on the v-dimm--they had to be recalled/rma'ed as no psu-ram combination could fix the problem .

it could be a number of things-- it might be the result of a bad bios flash as well--some of the nf-4's had problems after being flashed--the bios wouldn't clear all the old data--it would just write over --one of the things that this would cause would be hard starting --sudden out of no-where crashing , rebooting and sudden mb-death .

just keep at it as it could be a small item --like a bios overwrite that caused the issue .
 
Thanks for the response.

I have tried 4 different bios's, same thing.

Remember, this system has had zero problems for a year until I dropped in the dual core.

Putting in the opty 148 fixes the problem immediately.

I'm about to buy a new PSU, tonight I'm doing a long cmos clear and that's my last straw.
 
Just got done with a 46 hour long cmos clear, and the problem is still there. So I'm thinking that the 500w Fortron Blue Storm is not enough power for this dual core chip. Which shocks me. So I just ordered a OCZ OCZ700GXSSLI and this better fix the problem.
If this problem is still present after the new PSU gets here, I'm tossing this computer out the window :)
 
I had the same cold boot issue when i first had the board. The problem was due to the ram voltage. THe mobo allowed you to oc the voltage via jumpers to 2.5v .Setting the ram voltage jumpers to back to default fixed it for me.
 
The system has run fine for a year, once i put in the dual core it changed.
It's not the Ram voltage. If i put in the opty 148 it works fine. So its an issue with the dual core and power. I just ordered a 700w ocz and this better fix the problem.
 
these dfi mb can be very fickle about psu's . on my infinity 975x some of the expensive 600w psu's gave problems. hard boot ups. crashes-ect. but on a lark installed a chepo 500w roswill and the damned thing ran fine . go figure!

the problem is with the v-dimm undervolting on start up most likely . i can't recall but i think fortron , antec and some other psu's had major problems with the ultra d .

it's been a while since i ran the ultra d's --but it seemed they ran fine with the old antecs, but had problems with the new made in china antecs.

if it was me--before i bought any psu--i would search the net and find a list of psu's that work with this ultra d mb. DFI's generally hate some psu's .

my ultra d would run fine with a old tp-450 antec and the old tp-550w with 20pin --but it had boot up problems with the much newer tp-2 550w/24pin . the dfi's need a high quality power more than they need high wattage . but one with plenty of amps on the 12v line helps.
 
I think everyone is ignoring the fact that I keep mentioning that this PSU has had ZERO issues for over a year. Once the dualcore went in, that's when it started. Its not like i just bought this PSU and it gave problems from the beginning, no.
The situation is the CPU, heres a quick breakdown.

Dualcore installed = boot problem
Singlecore installed = No boot problem

And I dont believe its the CPU cause it's prime stable when its working. Which leaves me the PSU as the last culprit. If it was the mobo, it wouldn't work with the singlecore.
 
considering i run my system on a 450 watt and i have no problems, i dont think thats the issue. i know my board sometimes doesnt like to restart properly, but the cold boot issues i had were fixed by an rma of a ram stick. try running memtest with your 148 in there, and then try with the 170. either there is a bad mem controller, or the 170 is more picky than the 148
 
Does anyone feel this could be a NF4 Chipset Driver issue? I believe I'm using 6.53.
Should the NF4 Chipset driver be updated to something newer? Does the chipset driver need to change to support dual core chips?
 
I am having the same issue with my DFI board, the problem only appeared when I upgraded from a single-core opteron to a Dual-Core.

Switching the PSU (Hiper, there is nothing wrong with it when i swap the single-core back in) off and waiting 5 secs then switching it back on fixes it for 1 boot.
 
sounds like we are in the same boat. Try puttin in your single again, mine works fine when I do that.
I will give you a heads up when this new PSU arrives. Hopefully it will solve the problem.
 
Update:
Got the OCZ 700w yesterday, installed, zero problems booting so far. Every time I have turned the system off, it has powered on the first time I've hit the button. So I believe its solved for now. I was really worried thinking if this didn't work, then it had to be a mobo issue.
Thankfully everything has been cooperating. Maybe a weird side effect is the fact it seems that my load temp has dropped a few degrees. Not sure why, I do have the sides off the case, but I dont think that will make that much of a difference.
I will have to rewire this badboy here soon, this PSU is a mess with wires, they are everywhere! Will keep you posted, thanks for the help everyone :)
