Intel Core i7 3820 not run in EVGA X79

^^^ FF means the board is failing to post.  Please test the motherboard outside the case on a non-conductive surface. Only plug in the 24 and 8 pin connector, the CPU and the CPU heatsink/fan (nothing else).  And let us know if you still get FF.

i checked right now the pins on the CPU and seems they are ok...i never heard about so many failure on intel CPU..
 
So what's the next step to do for u?
 
 
PS i did connect 2x8 pin 12v power connection on the M/B is that correct or is better to start with only one?

ok...i did put M/B outside the case on non conductive surface just 24pin and 8 pin power supply and cpu with heatsink and i get the same issue....
 
....damn FF code
 
so what now? make harakiri?

use this troubleshooter

the problem still...

Your in the same boat I was... So I called EVGA did an adv RMA and also got a bios chip sent to me. I still got the FF code in both boards with the new chip.... So for me it was the CPU. You can do the same thing if you want. Give EVGA a call. Or call your retailer and have the CPU replaced.

i'm reading on intel forum that they have many problems with intel DX79SI board. Seems that they cannot star the computer because of an old bios and they dont have the chance to upgrade.
would like to know if i change processor like 3930k i will have the same problem..
I found on evga.com a compatibilty list where is written that x79 boards are compatible only with 3930k and 3960x, is that possible?
 
X79 Series Motherboard (LGA 2011)

• Sandy Bridge E
  • Core i7 3960X - 3.30 GHz
  • Core i7 3930K - 3.20 GHz

FYI, anyone can ring the US number, as long as you don't mind paying the international fee. I've done it once before and whomever answered (this was probably around 5 years ago) was very helpful with the issue I was having with my GPU.
EVGA went well out of their way to help me with my issue.

I did try 3820 CPU on an asus P9X79 delux and was working fine so is a mobo bios problem...
EVGA is sending me a new bios chip hope this will solve my problem.
 
thx a lot to everyone

Hi Jelial80,
 
let us know the result 

I'd be surprised if a new BIOS chip didn't fix your issue then if the CPU has no issues in another board.
Enjoy your system when you get the new BIOS :)

i've read intel forums that they have teh same issue with intel boards...but they are unlucky because is not possibl to change the bios chip so they have to find someone that will borrow them a 3930k or a 3960x chip to run the new bios and fix it!! that is insane!! a new intel CPU that doesn't work on an intel board?
 
btw my new bios chip is movng from germany to italy right now it will arrive next week...hope this will fix everything because i want to build my new desktop!!!
 
i will let u now soon!!!

in my classified with bios 35 one of my xeons running fine and with the 3820 the same bios 35 is ok for I7

Ok....or not? not because my desktop still dont work and I dont know what to do right now...i already send an email to the EVGA support but right now i really dont know what to do....

Hi,
 
Jelial80, look at new release Bios 36...maybe could help you. 

Ok look at the big deal now:
I sent back the M/B with the CPU to drako.it official dealer and they try it with the 3930k CPU and it works correcly!!! they update the bios with the last one (36) and the 3820 doesnt work!! how is possible that the CPU works on certain motherboards and other not? and we are talking about only on different EVGA boards!!!
 

Yes, I believe that the X79 Classified is only compatible with the 6-core processores. I purchased an X79 Classified and a 3820 cpu - it does not work, producing the same behavior you are seeing posts an FF to the onboard display for about 20 seconds, then resets itself.
 
Pretty frustrating - this is not called out anywhere in EVGA docs.
 

Followup 6/8: just talked with evga tech support, and the word is that with the latest bios, it will work.  Given the serial# from my unopened box (from newegg) they say it has the latest bios and it should work for me, and if not, various RMA/cross-ship/bios replacement options are available.  It would be real great if evga can document this somewhere (CPU compatibility list, the pdf docs for the three X79 models, ...) to avoid this hassle for all involved.  However, hats off to evga tech support.  Looks like I'll be building this weekend after all!  (watch this space as the drama unfolds, my last build was in 2005 and is still my main computer, I'm hoping to get 7 years outta this build as well.)

Can anyone from EVGA state specifically for the record if the 3820 is or is not compatible with the X79 Classified.  I have just bought both from newegg, not seeing that this crazy incompatibility may exist, and I do not want to open either box until this issue (or non-issue) has been clarified.  This will cost me either the restocking fee on the mobo or the $300 CPU is worthless and I will have to buy at $550 CPU.  I can't understand how the X79 classified can only work with 2 CPUs, one of which is $550 and the other approaching a grand.
 
EVGA Please state for the record what the situation is.

I'm having the same issue tonight. EVGA X79 & 3820. One thing I want to mention is as soon as I remove the 8 pin power the board stays powered on. No more on/off mumbo jumbo. Def a 3820 issue in my eyes on MOST X79's. Guess I need to get a 3930???

Dropped a 3820 in my RIVF and bam..........about three minutes later I was stable at 4.5ghz. :P 

I have an i7 3820 on my X79 SLI vanilla motherboard and it works very well

Here is my result... EVGA sent me a 'updated' BIOS chip and I put it in with the 3820 no go. I went out and purchased a 3930 - BINGO it works! Then I look and the chip they sent, it was only flashed to 032? Sooo I flashed to 037 with the 3930. Then pop in the 3820 with 037 and - BINGO it works! So if EVGA would have sent me the most 'updated' 037 chip, I wouldn't have had to purchase a 3930k. Happy and frustrated.  

EVGA Tech Support told me my 3820 WOULD NOT work in the SLI even after I was given a NEW bios... I was sent a brand new updated MB...

What will a new board do if they are stating the 3820 wont work with the SLI?

If you are getting FF and have tried your chip in another system and/or another chip in your system to narrow it down to the board we can replace it. Please email me matth@evga.com and I can set it up for you.

Geez rather lame being 100% disabled and after spending about 2K ER in this build:

I get the FF nonsense also, I am so tried with this, I just have no idea what to do, making pdf's of payment papers is impossible since I have no printer, so that is out of question.
 
I just need a simple solution I even plan on selling it all, this has truly been the last 1CPU build in my entire life, just due to similar bad experiences low quality hardware parts, it explains it all, this should not be accepted for a 350 EUR motherboard, just unacceptable.
 
It's all too unpredictable and too unreliable.
 
All the parts are brand new, not even 8 days old, even that DOA is possible, it seems most unlikely, sorry but I am very upset at this very moment
 
Great news I got it working :)

it's all there my friends, after switching the bios switch to the middle and doing a reset CMOS I got it working :) Bios ersion I have is 0.32 the i7 3820 is neatly detected in my bios, happiess!!!!

As Tech Support told me its something about the microcode. My USB 3.0 did not work, I had NO Lan. I was told that there were hardware corrections that were needed to INSURE that the 3820 will work. It does work in SOME cases, JUST not mine. It is what it is and Tech Support has been EXCELLENT and while I am still working through other issues I am sure everything will be fine in the end!
