Alrighty, here is your answer folks. I went to MSI, EVGA, Intel and Finally Nvidia to get to the bottom of the error. You will notice if you do a fresh install of windows or completely delete the nvidia drivers, the problem will go away. I confirmed with Intel support that the issue is definitely deriving from the PCIE bus, but rather than the bus itself it is whats plugged into the PCIE root. I came to this suspicion because I only get two of the following errors:
A corrected hardware error has occurred.
Component: PCI Express Root Port
Error Source: Advanced Error Reporting (PCI Express)
Bus:Device:Function: 0x0:0x2:0x0
Vendor ID:Device ID: 0x8086:0x2F04
Class Code: 0x30400
and
A corrected hardware error has occurred.
Component: PCI Express Root Port
Error Source: Advanced Error Reporting (PCI Express)
Bus:Device:Function: 0x0:0x3:0x0
Vendor ID:Device ID: 0x8086:0x2F08
Class Code: 0x30400
both of the buses above are filled with nvidia cards but the 3rd slot
Bus:Device:Function: 0x0:0x1:0x0
Vendor ID:Device ID: 0x8086:0x2F02
is filled with my Soundblaster ZXR and of course.....no errors.
So I went to Nvidia, and low and behold it's a known issue. Something has changed with x99 and the way PCIE works, so nvidia is working on a new driver that will fix these WHEA errors. See the log below of my convo:
Karthik: Hi, my name is Karthik. How may I help you?
Matt Guy: hey how are you
Karthik: I am fine thank you Matt, hope you are doing good too :)
Matt Guy: Well sorta, I have an issue I hope you can help me out with
Matt Guy: are you ready cause it might be a tough one
Karthik: Sure, bring it on. I will try my best.
Matt Guy: Alrighty. So I bought the new x99 Sli plus motherboard from MSI as well as an i7 5930k. I have 2 EVGA gtx 680's in Sli that I transferred over from my old z77 intel 3770k build. For some reason as soon as I install the latest nvidia drivers, my computer starts producing the following error code about 25,000 times a day.
Matt Guy: A corrected hardware error has occurred.
Component: PCI Express Root Port
Error Source: Advanced Error Reporting (PCI Express)
Bus:Device:Function: 0x0:0x2:0x0
Vendor ID:Device ID: 0x8086:0x2F04
Class Code: 0x30400
Matt Guy: under windows system event logs
Karthik: I am checking..
Karthik: This seems to be related to the kernel issue of the PCI express architecture (the error occurring randomly through the motherboard)
Matt Guy: Any idea on how to fix it? is it a hardware issue or something that a motherboard or Graphics card bios can update?
Matt Guy: or do I need new nvidia drivers that are more compatible with X99 hardare?
Matt Guy: hardware*
Karthik: It does not seem to be a hardware issue but checking this for now, it seems the issue could fix with the next software update from our end.
Karthik: Yes it needs a newer driver update for the compatibility with the NVIDIA card & X99 hardware
Matt Guy: alrighty thank you, yea the last thing I would want to do is send my motherboard back and wait for a new one to run into the same issue LOL
Karthik: you are welcome Matt, hopefully everything should be fine & working. You may watch out for the new releases.
Karthik: Thanks :)
Matt Guy: Are you 100% sure on this answer? Just because I am in contact with many people in the forums having this issue
Matt Guy: if you are sure I can provide a response to all of these Nvidia customers and help out quite a few people who are in the dark
Karthik: Yes I am sure, I do not see any other issue apart from this. The hardware is just fine & the problem is SLI specific only. You can wait for the newer updates & test this again. It should work.
Matt Guy: ok, when I disable Sli though, I still get the errors :S
Matt Guy: the cards are still plugged in physically together, but I disable Sli in the nvidia control panel, and I still get the error
Matt Guy: sorry I'm not trying to be difficult, I just want to make sure that there is a fix coming, because im going to let quite a few people know that something is comig
Matt Guy: coming*
Karthik: Yes, there is no information on this further due to compatibility or other issues. You can keep updated that the future driver release should work for this issue Matt (specifically with x99 motherboards )
Matt Guy: OK good stuff, I'm glad you guys are working on it! do you have any type of eta on a beta driver release date for this fix?
Matt Guy: also is there something different in the way that x99 handles the PCIE bus that makes nvidia cards fail with it?
Matt Guy: that was the last question i promise LOL ^^^
Karthik: I am sorry, the driver releases are all scheduled by the development team. There is no specific ETA for now but you can check this from the GeForce.com site & the I have no access to QA details that test the way x99 SLI Plus PCIe is compatible or certified with the NVIDIA cards. So this will be internal data.
Matt Guy: but you do have knowledge on your end that this is a known compatibility issue at least?
Karthik: Yes, I have seen issues reported on this model compatibility hence one of our updates should fix it.
Matt Guy: alrighty good stuff, that's all I needed to know, I shall wait for an update, thank you very much, you've been most helpful
Karthik: you are welcome again & thanks for your time as well.
Matt Guy: is it ok if I copy and paste this to the EVGA and MSI forums for the people that are having this issue (there are other people with the same problem). they will be very happy that a fix is in the works
Karthik: Sure you may post it, no problem.
Matt Guy: Thank you and have a great day
Karthik: I would be happy, if this helps.
Karthik: Thanks, Goodbye!
Hope this helps all of you others that are having the issue. Cheers! hang in there and keep clearing your logs for now LOL
