DFI NF4 smoking&burning

[amduser]

I`d be tempted to blame the board over the PSU, but thats just me.

the seasonic s12 he has bought is a pretty good psu. too the too tagan's he had before. it's just the throught that dfi is too not the BEST BOARD ever. it quite good. but it'S slow and i know a lot of peopel haveing serious trouble with that board.

EPoX nF4 or MSI K8N Neo4 paired w/DDR BOOSTER might be a good combo. My board gets 300HTT fine (Neo4 Plat REFURBED ).

[Primoz78]

What about a BIOSTAR Tforce4 SLI ...anyone have it or have some tests?...

Epox NF3 and4 boards dont work with the DDR Booster. The Epox 9NDA3+ can be voltmodded very well for extra DIMM coz it uses the +5V rail for the derivation, but not the 9NPA+. That uses the +3.3V rail. Just saying so noone kills their board that way..

The Epox boards will do 315+ (CPU limiting and I cant be bothered to drop the multi to find out the HTT limit)

I dunno, i'm not motherboard engineer, but that doesn't look like a power supply problem. If something overvoltaged from your PSU, your other hardware would be damaged as well, hard drives, memory, ect - also i think those caps near the voltage regulators would have popped - see the Y looking etch at the top of the cap, that is where it is supposed to open if it is overvolted. It looks like the regulators overheated, fried and became shorts - the land that is fried on the bottom of the pcb looks like it is under one of those regulators, the 2 leads just to the left look like that is where the caps are (and look fine)...

It is not the PSU.
In Germany we had a great PSU test a few months ago and the Seasonic passed. Raisl were stable and the Ripple was within specs!
The Seasonic shpuld do great. I think you had bad luck with your motherboard.

Its threads like these that 'scared' me into buying the new Asus board.

Unfortunately, thats not how it works. I've had bad boards from just about every company. The biggest blow out of all (actual flames) was on an asus p4p800 2 years ago. Stuff just happens.

[da-key]

Oh man I had to order a ultra-d just to see if I can make it burn

How can I call 3 time RMA for DFI boards in 4 months...I don`t call it bad luck but bad boards . The seasonic was new and it ran about 10h...so I think it was the PSU the cause...I have tryed the ram and it is OK...but don`t know for the CPU, VGA and HD yet... I have send the Seasonic back to the shop cause I`m afraid to connect it to a new MOBO...I`m going on a Enermax Liberty 620W now...

p.s. I have written an e-mail to DFI Netherlands now I`m waiting for respond...cause have made a post on DFI-street but noone from DFI has answered...

[hipro5]

My water cooling?...the water cooling is ok and there was no water in the case! And I can run it now and it is ok!...here are some pics of my board...So DFI has respond to RMA...and told me that this kind of situations are not covered by the guarantee...so I can go and buy a new MOBO...which I thik it will not be a DFI They said this is an voltage and PSU issue...I have tested my ram for now and it is ok...the CPU and GPU wansn`t tested yet...So here are some pics:

So here it is...the PSU (brand new...about 4 days old) is going back to the shop, cause I`m afraid to connect it to my new board!

Showing the pictures you have uploaded, it seems to me that the VCore Mos-fets has blown up......I think that the heatsink that is on the Mos-Fets for cooloing them down, DIDN'T have a good "contact" with them.......Maybe the company which builds and solders the components for DFI, didn't use much presure on the heatink when they puted it on for soldering, so it didn't attached the VCore Mos-fets well OR not at all.....

I DON'T think that it is related to the PSU........

You R wright...the PSU seems to be ok after a few tests in the shop...but I have received an e-mail from DFI...

Dear Customer,


Thank you for taking time submit us the query. As per your photos posted on forum, improper usage might be the root of why reseller rejected your RMA request, we assume it’s from JP17, and that kind damage of burnt also caused your on-hand motherboard(s) become not repair-able. Enclosed captured page from User’s manual please find for your reference.

If you still have interest to purchase our product. We may still evaluate and provide you the direct service and special discount, please send us the information as below to confirm the products you had purchased.



1. A copy of your purchase invoice and from your reseller.

2. The Serial Number of the motherboard.

3. Your postal address and contact details.

4. The price of your purchased products (might also states on purchase invoice).

5. The reseller you purchased the motherboard from (also the retailer's website address if available)

As I understand it was an JP17 error or a "bug" as I read on other forums too...but also they now about the bug they don`t accept my MOBO in RMA...

Primoz

You need to invest in a good psu. IMHO

The 520 or 600 are great.

He has one already, as good if not better than the OCZ.

I'm glad someone agreed with me

To original poster: companies will always look to blame the customer during failure analysis, not just motherboard companies though. I've worked at a semiconductor company for about 7 years in the past, they will always look to pass the blame. I wouldn't take that excuse of a bug, and not being covered by rma.

[Primoz78]

Finaly got an answer from DFI...and they said that I will be grant with an "special discount" only if I can prove that has 2 or more of DFI MOBO`s before...they call this kind of people "DFI enthusiasts"... So as I send my two MOBO (I had 3 of them) in RMA I do not have the invoice any more . And the best part is...the offerd me a "special price" of 320 USD for an DFI SLI-DR Expert...shipping included... ...WTF...this is a lot much than prices in EU!

But here is the worst news....my Opteron 146 0540 FPMW has gone

How it is possible as the DFI said it was the JP17 jumper the fault...I thought if the JP17 cause the burn out of the MOBO the ram should go with it too...but not the CPU...

p.s. DFI has lost one costumer today...

The PSU wasn`t the cause...It was tested and it seems OK...but I gave it back in RMA for precausion...I`m waiting for an Enermax Liberty 620W...Hope will get it next week...

It's not the jumper......The VCore Mos-Fet blowen up and it may had pass 12Volts to the CPU's VCore

[Primoz78]

Thx for the explanation...Now I`m looking for a new MOBO...and it won`t be a DFI I promisse!...

Stop overclocking NOW!


Sell your gear and take up knitting while you still can.

THREE BOARDS IN A ROW!!
What are you doing to it?

[MadMikeSS]

You wanted to go extreme so thats what you get man, live with it, move on , stop complaning. If you had left everything running at stock non of this would have happend. Three in a row? I dont buy it, sorry man, most if not all pc related problems like yours are from user-error. No offense, just my opinion.

I have to agree with you there. I could see one board, but not 3 in a row.

[Primoz78]

What are you doing on this forum?!...The name it`s Xtreme systems and not stock systems! As I said before the DFI boards are used to be overclockers boards and there was not an extreme overclocking on my system the boards had bad components and thats it! Noone of my friends that has systems like mine but more OC`ed don`t have this problems...I mean a "screaming board"...For one board was my fault but two of them has gone for them selves!...Just look at the mails I have attached that DFI send me...

Regards and no offense!
Primoz

p.s. I think it this theme it could be locked now...!

[B5I8]

Same thing happened to me. It killed my CPU. You're lucky you can RMA. I can't RMA the board because it is covered with insulation from my phase change, and I can't RMA the proc because it is out of warranty already (Damn OEM warranty's).

[fareastgq]

Here's some info in one of my threads about my opty 175, it has a mini review of 3 m-atx boards. biostar 6100 T series is one if them, I recomend that one, but really only if you plan to build an actual M-ATX system. The asus is nice in every way EXCEPT u might hate the v-core limit.

[Primoz78]

Thx fareastgq!...I will look at your review...I will receive 7 Opteron 146 0540 APMW this week and I would like to have an MOBO till today...So I have to decide quick Thanks for suggestions!
