RAM not being seen in bios or Belarc. is there an online Ram/motherboard diagnostic tool?

[trinityx]

Hi All!
My wonderful computer is finally put together and running. I ran Belarc and saw that one of the ram sticks wasn't showing up (slot 2), so I took it out and put it back in again. Ran Belarc again and it still shows only the stick (in slot 4.)

I looked at the bios and again, it only shows slot 4 being filled and not slot 2....is there a diagnostic that I can run that will see if the slots are all ok or if there is a problem with them?

This is what my rig:
This is the spec of my system and the ram:
Board: Z170a Pro
BIOS: Version/DateAmerican Megatrends Inc. 1.C0, 7/23/2016
Video Card: MSI Geforce GTX 1060 6gb
PSU: EVGA 500B
CPU: Intel Core i7-6700k Skylake
RAM: 2x8GB 3000MHz G.Skill Ripjaws V F4 3000-C
HDD: WDC WD10EZEX-08WN4A0 [Hard drive] (1000.20 GB)
COOLER: Cooler Master Hyper 212 EVO
Keyboard: Logitech G710
Mouse: Logitech gaming mouse (I don't remember what # it is)
OS: WIndows 10 64bit Home Version.

So the slots go A2, A1, B2, B1.

Try putting both in slots B2 and B1.

Also try A2 and B1.

If A side slots are bad you probably have something wrong with the motherboard. I had a bad pin in the CPU socket which threw the B side slots on my board.

You can use memtest86 to see if any errors are thrown by the ram, which means the ram is actually bad.

If the one stick isn't working, try putting that stick in slot A1 and see if it works too.

Thank you Staplergun It was weird, it sorta resolved itself. I took the sticks out, put them back into their slots (fully expecting an issue and was going to do what you suggested), I ran the memory program that windows uses (memsys? not sure because that was this morning), rebooted the machine and then it all worked, both of the sticks were ok and active. I think that maybe they weren't sitting exactly how they were supposed to...or something. I can't even blame it on a full moon... Thank you again

Sometimes ram is picky.

Could still run Memtest86 on them to ensure the ram sticks are not bad. Never hurts. I just got new ram in yesterday and ran memtest on them to make sure.
