[SOLVED] Can't get Bios - is it a RAM mobo mismatch?

[trbrisbin]

I'm building a NAS system and am using the following mobo, processor, and RAM. The system powers up (no beeps from the speaker attached to the mobo), and stays on. (The ethernet port's indicator light powers up too). However, I don't get any display off of the mobo's video outputs. (No GPU, multiple output types/cables tried). I've tried all the normal troubleshooting and am wondering if it is because I am having RAM/MOBO compatibility issues. The Mobo claims to only support DDR4 up to 2133 with my 6th gen skylake processor. However, I've got DDR4 2400 plugged in, and the intel B250 chipset of the mobo isn't listed under the supported chipset in the RAM's specs...

Is my failure to post bios a compatibility issue or something else?

No the RAM isn't probably causing this. Almost every RAM kit out there is perfectly capable of working at lower clock speeds. So something else must be going on.

1)Try to clear the CMOS.
2)Try to use one RAM stick at a time in every available RAM slot.
3)Try to re-seat the CPU and also check the CPU socket for bend pins.
4)If you have a speaker attached to the motherboard, remove both RAM sticks and try to boot. If you are still unable to hear beep codes then the motherboard is probably faulty and you need to replace it.

That's what I suspected, but have been grasping at straws. It does sound like a mobo problem. I tried 1-4 with no luck. I may attempt to get a new mobo speaker - the one I'm using is several years old.

Thanks!

Memory modules sold as Singles have no guarantee to be compatible in any configuration other than as a Single module.

I suggest getting a kit of two 2133MHz modules.

Yes you are correct but I believe that he tried to use them in single mode and they still didn't work. So in this case something else is probably going on.

Yup, tried with both sticks in single mode and neither worked. Tested my speaker on a functional system and got a beep. Time to exchange the mobo for a new one.
