  1. Nobody wants to touch this issue. It's sad that EVGA will not even address it in their own forum...
  2. After a call to EVGA I can confirm that all EVGA X99 motherboards have a part 1 and part 2 product manual. Part 1 is specific to the individual motherboard while part 2 is a general X99 installation manual that comes with every X99 motherboard.
  3. Not to mention I had it running in x16/x16 when I had the 2 EVGA 780ti SC running on the board.
  4. I see what your talking about page 10 of the part 2 manual. Interesting it contradicts part 1 of the manual. I am pretty sure the part 2 is a generic manual for all of EVGA's X99 boards. It says X16 on slot 1 and 4 stamped on the X99 Classified motherboard. Only the EVGA X99 Classified and FTW motherboards supports x16/x16.
  5. What about it ? It is part 2 of the manual. Part 1 has the PCI-E lane distribution chart. Product manual Part 1 https://www.evga.com/support/manuals/files/151-HE-E999_Part1_v2.pdf Part 2 https://www.evga.com/support/manuals/files/151-HE-E999_Part2.pdf
  6. Please guys check out the other thread there is a ton of info and pictures on there already. It is not a long thread.
  7. Here is a picture of my 780ti's in x16/x16 all the same hardware only difference is the 980ti's.
  8. No slot 4 is a x16 slot. My 780ti's ran x16/x16 with all the same hardware . Check out the thread I linked above. Here is the product manual. PCI-E Slot Breakdown PCI-E Lane Distribution (40 Lane Processor) PE1 – x16 (x8 if PE2 is used) PE2 – x8 PE3 – x8 PE4 – x16 (x8 if PE3 is used) PE5 – x4 (Gen 2 only, 4 lanes pulled from PCH) PE6 – x8 PCI-E Lane Distribution (28 Lane Processor) PE1 – x16 (x8 if PE2) PE2 – x8 PE3 – x8 (Slot is *NOT* functional with a 28 lane processor.) PE4 – x8 PE5 – x4 (Gen 2 only, 4 lanes pulled from PCH) PE6 – x4
  9. I found a problem with EVGA 980ti Classified's ! It seems they do not support x16/x16 PCI-E bandwidth on the EVGA X-99 Classified motherboard even though the board is suppose to support x16/x16. This is a problem with both the 5930K and the 5960X which both have 40 PCI-E lanes. I have not been able to test it on any other motherboards. Below is my original post on the EVGA forums and here is a link to the thread http://forums.evga.com/980ti-Classified-2way-SLi-PCIE-lane-issues-X99-Classified-MB-NO-x16x16-m2399449.aspx I am hoping somebody here can help figure this out or that the Linus Media Group could talk about this in a video or on the Wan Show. System info : EVGA X99 Classified E-ATX motherboard Intel 5930k custom water loop 16gb G. Skill 2666 DDR4 RAM EVGA SuperNova P2 1000w power supply 2x EVGA 980ti Classified I installed 2x EVGA 980ti Classified GPU's a few weeks ago. They are installed in slots 1 and 4 EVGA's product manual says these are the proper slots for 2way SLI on this board and they should be x16/x16 with the 40 PCI-E lanes from the 5930K. I have the extra 6 pin power plugged into the motherboard for the PCI-E slots. For some reason slot 1 is reading 3.0 x16 but slot 4 is reading 3.0 x8. Why is slot 4 x8 and not x16 like it is suppose to be?? Is it that the GPU just can't use the bandwidth ? I tried pushing the cards with Heaven benchmark, 3d Mark, Furmark and it stayed at x8. I have tried disabling the other PCI-E slots. I have both the m.2 slots disabled. I have no other hardware in any other PCI-E slots. I also noticed that in the Nvidia LED configurator that the card in slot 4 is reconized as card 1. I am not sure if thats normal or just a bug in the software. When I had my 780ti's in they always read x16 on both slots. I just can't wrap my head around this. I know there is no real performance gains from x8 to x16, but I bought the 5930k specifically because it had 40 PCI-E lanes. I would like to be able to use the lanes and hardware as stated in the product specifications. If anyone else can confirm this with a similar set up please do so. Any help or input would be appreciated!!! I can post any pictures or info needed.
