Here's the story;
 
finished this build Sunday;

Z97 Classified with latest bios on the board
4790k (Silicon Lottery 4.8)
32GB of GSkillZ 1866 that does 2400 10/11/11/27 1T at 1.65 volts on a HERO/Extreme 6/Z97 Classified 24/7
EVGA 1200 P2 
2x evo 840 1TB with fresh 7 Pro install
1x XTX 360 kit with another XTX360 and XTX240 all P/P
2x EVGA 980 KPE
Case Labs S8

Fired it up no issues - installed all the latest drivers at 44 at 1.25 42 at 1.20 volts no issues. Ran FS/FSE benches (no OC on the SLI) no issues. Formatted the 2nd Evo. 

Bumped to 4.9 at 1.30 volts ran the benches again no issues.
Bumped to 5.0 at 1.35 volts ran the benches again no issues.

Decided to run FS loop over night at 5.0 setting..... in the AM the screen was blank, would not wake. 

Moved it to where it's gonna reside..... plugged it all up and nothing. All the fans power up, pump is running. 
I swapped DVI cables, nuthin, tried HDMI nuthin.... went to work scratched my noodle all day  tryin to finger it out. 

Came home checked the codes 62 found out it's actually b2. 
Check around for b2 meaning CPU? Tried with 1 stick of ram nope, swapped with my 4770k from my other box on the Extreme 6 same thing. Yeap, I check the pins nothin outta wack there. Reset the bios a couple times throughout all of this.

I can't believe the cards are trashed but have yet to try my 980 AMP Extremes from the other box yet. 
 
AFTER I removed and tested each card separately I had the same issue. I then installed another set of 980's I have on another system running perfectly in the same box.... BINGO boots and runs fine. I then installed each KPE in the other box.... same b2 code. I then removed each ACX cooler and replaced the TIM with Artic Silver and tried again.... same b2 with each card in every slot.
 
I sent EVGA a RMA request at 7ish AM central time and by the time 9 AM rolled around I had RMA's on both cards!
 
Top notch service!
 
I'm only posting here to possibly help others with b2 code issues.

You are saying that overclocking your CPU fried the KP cards? Both of them? 

Nope.
I'm saying they both failed in SLI someway somehow not sure. I'm saying that I ran the same setup (the EVGA bridge does light up on a non-EVGA card BTW) with the same settings doing the same test and it was fine this morning. I'm saying I tested the KPE's in the box the other 980's I used last night came from and got the exact same results in single card or SLI regardless of the slots the cards were installed. I'm saying that EVGA provided the fastest response to my issue I've experienced on the web.
