Running two cards in 2 and 4 should have a minor impact to temperatures. I've run two 760s right next to each other before upgrading my motherboard, and I saw a 1-2 degree difference in temperatures under benchmark loads once I had space between the cards. If you have good airflow, the spacing won't be a problem. 
 
Slot 1 should still run at 16x with a single card in the system.

Regardless, the board should work the way it was/is marketed and people plan a build around. I bought it cause I was wanting to run a second 780 ti in SLI 16x/16x...Slot 1 and slot 4.
Yes, the board seems solid other than a few lil issues, but still solid. In the end, I paid almost $400 for a board for a one specific reason that is not there now.

ehh, of course not. it will come down to 'we made a typo on the lane reporting and you have to use slot 2 and slot 4 for dual SLI 16x/16x, not the primary slot 1(common) and slot 4'. And btw, if you bought two cards for $1000+ and $380 board to run dual 16x mode and do not fit due to wrong slots having to be used...we are sorry but oh well, you understand...right?' :-/

Exactly

I agree, there should be a tech or more keeping us up to date. Im sure they know what they did wrong etc by now. I have 10 more days left to send it back to Amazon for a full refund so if in 5 days no info or more it will go back and an A**s will be bought. Thats all ilI have used up til this and will go back being Ive never had an issue...never.

Hey everyone, sorry it took so long for an update. I confirmed that there was a misprint in the manual about Lane 1. For 16x/16x, lanes 2 and 4 are the proper lanes to run your cards in, and I was told an update to the manual is forthcoming. I'm very sorry for all the confusion.

I might be interested rchapman, it looks like your in the UK?
I'd send you a pm, but I don't have the post count yet! 

Lololololololol.....

So it took 3 weeks for that? You order a board in for testing, when someone around there could have easily said... No, that's a misprint, the board can't do that??

Thanks the help jaeson, I know you are just a messenger. There is a sad state of affairs over at evga lately... What's going on?

My video cards are unable to be put in slots 2&4 because of another un-disclosed design flaw with another one of y'all's products... The 560ti 448 core classifieds. So I bought this board specifically because the manual stated I could use slots 1&4. Only to be shafted again...

Fool me once, shame on you... Fool me twice......... You're not gunna fool me again... President George W Bush 😆

I'm not going to whine or request a refund... I have learned my lesson... But if EVGA are honorable business folk, they would be discussing some other means of compensation. Maybe evga bucks or something. I'll hold my breath.

I will get new video cards soon that will be able to run in slots 2&4. Or may be just get 1 card.... Some evga bucks might go a long way toward parting with my hard earned money to evga for that purchase. I will be looking at other options.... That is fuuuuuuuuuuuuuuur shhhhuuuurrrr!!!

It pains me to say that... Oh well...

hello
 
test on my FTW97
gpu R280X 2x
test slot 1 and 2 8x 8x read in bios
 
test slot 1 and 3  16x 4x read in bios

Try slots 2&4. That's what is 16x/16x on the classified.

Am having the same issue. Got it runing 1st & 4th slot read 1-8x/4-16x 3Gen, course when I move it to 2nd & 4th slot it read in the bios 2-16x/4-16x 3Gen, but to my understanig slot 1 runs of the CPU. I been following this thread for a while hoping they come with a solution on the bios, other wise I'll be requesting for a refund and move to and Asus or MSI. This is the main reason I boght this board to have crossfire at 16x/16x not 8x/16x.

Mine went back for a full refund with Amazon. What most of you here that are making comments about 16x/8x etc. do not get is us that are disappointed are cause not being able to use the correct slots (1/4) makes it very hard or impossible to run certain video cards in SLI cause they will be way to close or will touch. Plus, the fact we were told a board was being tested to see what was causing the lane reporting to be wrong and ' THREE WEEKS' later we are told it was a typo in the manual. Maybe three hours but not three weeks. Second, the sound was horribly unstable. I was either losing it completely or it buzzed and crackled causing a reboot to fix it. I had the latest bios and Sound Blaster drivers so there was nothing else to do. Finally, I would get random boot failure saying no memory installed causing me to do a clear cmos to get it to boot. And yes my memory was/is compatible. Just way to much going on for a $380 board. I bought a ASUS Z97 Deluxe and it has run flawlessly for a week. I have always used ASUS and decided to try an EVGA being I use their video cards and power supply, guess I learned a valuable lesson

Well said. I have actually never heard of a board having to not use the the primary slot as a slot in dual SLI. That is when I know something was jacked up. Now they may do a revision and fix it but to say the issue is a typo in the manual is really surprising to think they would actually believe us consumers would say "oh ok, no problem". It honestly makes me second think any of the products, regardless of them having a great video card. I have always used ASUS everywhere possible unless they didnt make a part, too bad they do not make psu's. When the 800 series video cards come out I will go back with an ASUS. I have a Supernova 1300w psu also, it has worked fine so far, they carry a nice warranty also.m

I've been with and have had Excellent EVGA products since 2008 always using their First run Motherboards, Graphics cards and accessories, But changed to an ASUS RIV BE for my X79 Platform due to all the ORIGINAL problems shown in the Forums associated with the EVGA X79 Classified and Dark Motherboards.
Although I'll still be using my original four EVGA GTX 780Ti KPE's with an X99 System, First I'll probably wait and see a few reviews on who comes out with a product that will run out-of the-box with no serious drawbacks, But I'm really going to have a tough time trying to decide whether I will put my money on an EVGA X99 MB or go again with another Brand.
 
I can only wait and hope EVGA releases a Truly Great X99 Product.

Thanks, dude, but I think think we've covered all the bases already.
