I've just built myself a new PC based on the ASRock X99M 3.1 mATX motherboard with a i7-5820K CPU and 32GB of Kingston HyperX memory (kit HX426C15FBK4/32)
One of the first things I did was go into the BIOS and check how everything looked, the BIOS was V1.0 so I updated it to the latest version (V1.30).
I then proceeded to install Windows 10 and had various problems, but eventually got it installed, but upon logging in I kept having problems, Windows would collect data and I presume send it off with a very short error message - these generally varied and were typical of memory/driver problems.
I then noticed that I only had 24GB of memory showing, and going into the BIOS also showed this - slot D1 was showing as empty. I checked the memory was seated correctly and it was, but it still only showed the three sticks.
So then I took out D1 and swapped it with C1, but it stilled showed that D1 was empty, so I was now thinking it was a motherboard fault.
Then I decided to try the backup BIOS, this was still at V1 and showed all four slots populated with memory, I tried several reboots and every time it showed a complete set of memory.
Switching back to BIOS A shows only three slots populated, even after multiple reboots, back to BIOS B and everything is OK again.
So this clearly seems to be BIOS related, anybody got any suggestions? As I would prefer to be running the latest BIOS as it improves over clocking compatibility.
Is it OK to flash BIOS A back to and earlier version so I can see how that performs?
PS. Full build log can be found here.
