Weird issues with Skylake setup
Hi,
I've recently built a new Skylake based setup, including following components:
CPU: i5 6500
Mobo: MSI H170 PC MATE (BIOS ver. B5)
RAM: Crucial 8GB Kit (4GBx2) DDR4-2133 CT2K4G4DFS8213
SSD: Samsung 850 EVO 120GB (latest fw)
OS: Geniune Windows 10 Pro 64bit
No discrete VGA card or any other PCI(e) device.
From day one I experienced several critical issues during operation, that is: numerous unexpected service termination errors in a row in the system log, BSODs on logon or shutdown with random messages. I reinstalled Windows 10 from scratch and immediately got same bunch of problems, without even manually installing any drivers (all drivers were correctly installed by OS) or software. Ok, then I suspected, this could be a HW issue, thus, downloaded memtest86 6.3.0, and went checking it. No errors were detected, so far, except for test 13, which has registered about 35 errors. Additionally, I ran Windows 10 built-in memory diag tool, and it indeed detected hardware problems in extended test. Unfortunately, I didn't have access to other RAM modules to try to swap them, but I had access to another SSD of same model and make. Just to be sure, I swapped it and repeated Windows 10 installation, but again observed the same problems. I then tried with one stick of RAM, then the other, with CMOS reset, from a different installation media (a USB drive), even Win 10 N edition. Always ended up with same problems! Eventually, I decided to give Windows 7 Pro 64 bit a try, and, magically, all problems just vanished away! Its been seven days already, but I yet to see a single issue! No error in log, no BSODs, just rock solid system! I ran verifier, sfc, mem diag tool, Prime95, Intel CPU diag tool and some other stress tests - no problem at all!
I've contacted MSI with this issue, but they could not reproduce it, since did not have access to this exact RAM, thought it is listed as compatible on both MSI and Crucial websites. However, they tested with same CPU and SSD, but did not find any problem. Had chat with Crucial supprot as well, and they did confirm, that if tests 1-10 of memtest86 are passed without an error, then RAM is considered non-defective. Test 13 is not on their routine test.
Now, my questions are: could this be a RAM issue, after all, but, then, why does it show up only under Win 10? I would like to hear your expert opinion. What is the difference between Win 7 and Win 10 in terms of interacting with HW? Could this be a SW conflict between UEFI, RAM and Win 10? is that possible?
Thank in advance for any input!
