Not posting after ram upgrade

[mikeybal]

I have 2x8 gb 2400 MHz ram running in my PC right now, and my friend got a ram upgrade and gave me his old ram. It's the exact same ram, 2x8 gb with the same latency, same brand and type, even same heatsink, but it's 3200 mhz instead. I tried adding it to the 2400 mhz I already have in my computer and it wouldn't post. Computer would turn on with fans and power LED for about 10 seconds, then turn off for about 20 seconds, then back for 10 seconds and continue like that until I forced a shutdown. After I removed the new ram, it worked fine again. What can I do to be able to install the new modules?

 

Update: both time I wrote 2x8 gb, I meant 2x4 gb. Also, my motherboard manual says that when using 4 ram slows, the max speed is 2133 mhz when all 4 are SR, and 1866 mhz when two are SR and two are DR. I think those mean single and dual rank but I'm not sure what those mean.

Try manually setting the speed to 2400 MT/s before inserting the higher speed DIMM's.

clear CMOS after installing new sticks. Will lose previous settings so you may want to save a profile before doing so

I can't do anything after installing new sticks, nothing comes onto the monitor so I cannot configure.

Can you check my updated post. Does that mean that I have to set it to 2133 or 1866 before installing new ram? And if so, which one?

clear CMOS is done by pressing a button or shorting two pins or removing the CMOS battery and let it sit for a while, no need to enter the BIOS at all. This is "hard reset" while applying factory defaults in the BIOS is a "soft reset", they are different

Oh sorry my bad I didn't know about that. I will look into that right away thank you.

I haven't changed any configurations in BIOS so far, will a CMOS update affect the settings on my PC?

BIOS chip holds the BIOS like an app while CMOS holds the settings of the BIOS, so a clear CMOS makes the BIOS start fresh apart from the profiles which will stay
