Should these Corsair Vengeance DDR4 RAM be compatible with this build?

[j.lodberg.hansen]

I've tried a set of these ram (Corsair - Vengeance LPX 8GB (2 x 4GB) DDR4-3000 Memory) in the below build, but they didn't work properly - sometimes the PC would start up, but most times it wouldn't at all. They've been RMA'd once, and the new identical pair received still have the same issue it seems.

Should the RAM be able to work with this build?

I don't see the memory on mobo's support page:
https://www.asrock.com/MB/AMD/A320M/index.asp#Memory
and corsair's page:

is equally empty.
Not sure what to tell you. I'd probably contact asrock to confirm since their list may be a touch out of date.

I have that kit on my ryzen build, but with a b350 motherboard. Won't go past 2666. Hynix based ram kits dont play to well with ryzen. Considering you have an a320 motherboard, i wouldnt try going past 2666. Does the system work @2133mhz?

Hi. The problem is the pc won't even start to BIOS. All the lights and fans start, but nothing shows on the monitor.

Can you clear the CMOS? try removing the battery for a minute while power is disconnected.

I have tried clearing it with the "switch" (small contact you move between 3 pins). Should it work better removing the battery?

 

[daswilhelm]

The switch should do it. If not try removing the battery. If that doesnt work, looks like you have a bad part somewhere.

We tested it with Crucial 16GB Kit (8GBx2) DDR4-2133 UDIMM and the PC worked fine with that pair, even when using just one of them. So it seems yeah, it works at 2133mhz.

I thought RAM were supposed to downclock its mhz if neccesary?

 

[daswilhelm]

They do clock at 2133, until you enable XMP. Sedivy posted above that your kit is not on your motherboards QVL. Try ram that your motherboard manufacturer recommends.

So it is possible that my motherboard just isn't compatible with my RAM?

Well...but it should be able to downclock to 2133 according to:
http://www.corsair.com/en-us/vengeance-lpx-8gb-2x4gb-ddr4-dram-3000mhz-c15-memory-kit-black-cmk8gx4m2b3000c15
as is mentioned in the tech specs. You just have to go to bios and turn off xmp which seems to be turned on by default and so bios resetting isn't helping.
But personally if you're able to return that memory or exchange for a price difference, I'd get something else. 3000mhz rated memory that's run at 2133 is a bit o a waste.
