GIGABYTE GA-X99-UD4 and I7 5820K

[davidst99]

Hi, I'm looking at the Gigabyte GA-X99-UD4 and the I7 5820K. I'm looking at the specs and wondering if I can run 3-way SLI and use the bottom port for a thunderbolt adapter or Wifi card or will that port be disabled? I think it can do 8/8/8/4 but not %100 sure. Could anyone double check my math Also, does the M.2 WiFi slot take away any of hte PCIe lanes? Thanks

with that cpu i would be very dubious intel 2011 cpu`s are restricted in their pcie lanes with certain processors no matter what the board is capable of....as point of interest google..the cpu and look at its pcie lanes that it can manage in your case it needs to manage 28 lanes ....on another note it is a board for use with dd4 ram look into that if your cpu can deal with it as well......i am not going to do all the work for you but if the chip,ram and pcie lanes are a go then you should get your 3 way sli....the m2 i am not shure about...if the cpu has 30 lanes you should be ok

Hi, thanks for the info. Its very helpful. I'll do some more research.

Yes, you can do it, with 8/8/8/4. 3-way SLI is supported. These charts will help you:

"Gigabyte chose to connect the M.2-slot through two PCI-Express 2.0 lanes from the X99 chipset: so a maximum throughput of 1 GB/sex. The marketing department has indentified the slot as 10 Gigabit/sec (which is factually correct due to the 8/10-coding), presumably to make it sound faster. However be aware that fast M.2 SSDs like the Samsung XP941 and the soon to be introduced SandForce SF-3700 models will not be able to work at full speeds on these slots. Another disadvantage of this solution is that the M.2 slot can not be used in conjunction with the first SATA Express connector or SATA port 5 and 6. Gigabyte call their solution "dual M.2", but this is more of a marketing thing. All Gigabyte boards feature two M.2 slots, but the second slot can only use a maximum of one PCI-Express lane, so not suitable for a hard drive. On the more high ends boards this slot is used for a M.2 WiFi module, something that it is suitable for. The only exeption to this is the Gigabyte XZ99-SOC Force, as this has what Gigabyte call a "Turbo M.2" slot, connected to four PCI-Express 2.0 lanes on the chipset. This is a slightly better solution but still not on par with the competition, as they implemented M.2 slots with four PCI-Express 3.0 lanes."

As long as you use the M.2 for WiFi, instead of an M.2 SSD, you'll be fine.
