I'm running a MSI Z975 SLI Krait Edition motherboard and I'm having a bunch of issues trying to pull my full internet speeds. I have 250 down and 20 up but my PC is only pulling average 60/20. I have testing it many ways. All my other devices when running speed test I'm pulling 250 over my wifi and ethernet to my server pc. I tried to run it directly into the modem by itself to see what I get but I'm still only pulling between 40 and 75. I went online to buy a PCI NIC and updated all the drivers and software for everything, and still pulling the same thing. The only thing I didn't do was update my bios but that is my last resort. I also have refreshed my PC and the same results. This was to make sure I didn't have any programs sucking it up. Any Idea's? I think my motherboard might be failing.
