Is Asrock RAM Compatibilty chart accurate?

Hello. I have an Asrock Z270 Extreme 4. I bought G.SKILL Ripjaws V Series 16GB (2 x 8GB) 288-Pin DDR4 2800 (PC4 22400) F4-2800C15D-16GVRB. According to G.Skills site. https://www.gskill.com/en/product/f4-2800c15d-16gvrb, this RAM is compatible with the Z270 Extreme 4 and that's why i bought it. I just checked Asrock's memory chart for the Z270 Extreme 4, and these modules aren't listed http://www.asrock.com.tw/mb/Intel/Z270%20Extreme4/index.asp#Memory/

Been having some memory problems where it isn't passing Memtest 86 (booted from USB) with both modules installed and even with both of them installed singularly. The same thing occurs with Windows Memory Diagnostic. I am getting BSOD's a couple times a day such as FAULTY_HARDWARE_CORRUPTED_PAGE, SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION, DRIVER_OVERRAN_STACK_BUFFER, PFN_LIST_CORRUPT. Since this is using Win 10, there are no stop codes. Here's a whole bunch of pictures I took w/ cell phone. https://photos.google.com/album/AF1QipOveMZOf_5ahOdDZWfrSSM5YiGs1x_wNpszb5ue

I purchased the main board, RAM, a new heatsink, and a 7700K. Using my old PSU (Enermax Liberty Eco 720W) and my old GTX 660 MSI Twin Frozr. Fresh install of Windows 10 on a brand new 120 GB SSD. Updated all drivers with Driver Booster, which I quickly uninstalled and manually clicked on EVERY single thing in device manager and made sure they were updated. Took a looooooooooong time. However, drivers don't explain the RAM failure that occurred in the tests booted from USB.

The reason I am questioning the reliability of Asrock's compatibility chart is that there is no Mushkin or PNY RAM that is listed as compatible. I find that odd. as well as the discrepancy with G.Skill's site.

I want to return the RAM to Newegg but I am not sure if I should get the same ones since they are not listed as compatible by Asrock even though G.Skill says they are. Is their compatibility chart accurate or should I trust G.Skill over them? Should i get different modules? Help. :-)

If G.Skill says it is compatible, it is. ASRock's QVL is only a listing of what they, ASRock, hand on hand in-house, and the not a complete list. Just what they tested. Always always look at the mem manuf's site.

You don't say, is this with the mem running @ 2800? My guess it is.

If the memory is not passing Memtest or the Windows Memory Diagnostic, that is the sign of one or more bad DIMMs. That is a sure sign it is time to RMA.

If you were over clocking the memory beyond its rated 2800 speed, then the errors could be caused by the OC.

Compatibility problems are shown by the memory not being able to pass POST, and the PC won't boot the OS. Or the memory only being able to operate at its default speed, which is never the advertised OC speed.

Memory is not compatible with a mother board, it is compatible with the memory controller that is part of the CPU in both AMD and Intel processors. Yes, the UEFI/BIOS of a board plays a role in compatibility, but the main aspect of compatibility is between the memory chips and the memory controller.

That is great to hear, it's always nice when a store takes care of you!
