NEW Ram causing boot loop

Hello,

So I updated my [8 GB Trident Ram](https://www.gskill.com/en/product/f4-3200c16d-16gtz) and added [16 GB Trident RGB Ram](https://www.gskill.com/en/product/f4-3000c16d-16gtzr) hoping to run a total of 24 GB of ram on my Gigabyte GA-Z170X-Gaming motherboard . But when I added the new ram my PC would just shut off and on continuously. I then took off the old ram and kept just the new 16 GB ram and the same happened. So I just put the old 8 GB ram back in and it is fine now. Any idea why this might be? Is the new ram incompatible/defective ? I read that either updating the bios or resting cmos might help. I dont have a usb drive right now so I haven't tried that, figured I try here see if its something else im missing before buying a usb stick.

When you installed the new modules, by themselves, did you populate them in the A2 and B2 slots, and did you THEN pull the power cord, remove the CMOS battery for five minutes, press the power button for 30 seconds, put the CMOS battery back in after five minutes, plug the power cord back in and then power on?

Did you also allow the system to train the memory by rebooting for no more than five times, while it trains?

If not, do that, and see what happens. If you can POST after doing that, then try powering off, installing the old module in slot A1, do the same thing with the CMOS battery again, and see if it will POST. If not, then it may simply be that those modules are not going to "play nice" together. This is not uncommon. It is...

If not, then it may simply be that those modules are not going to "play nice" together. This is not uncommon. It is why it is always recommended to purchase ALL memory together, in matched and tested sets.

You can also try, with whatever memory configuration DOES allow you to go into the bios, to bump the DRAM voltage up by .020v, save settings, exit, power off, install the rest of the memory (Do NOT reset the BIOS in THIS case) and see if they will POST. Often, with more than two modules, especially if you are trying to run them at their XMP values, you have to increase the DRAM voltage to get the memory controller to stabilize the configuration. Occasionally it's also necessary to slightly overclock the CPU if you are trying to run memory faster than 2400mhz, again, especially with two or more modules.

Thanks for the detailed answer, really appreciate it and no i did not try that. I will have to give this another go again tomorrow.

Adding the new ram in the primary slots and then clearing crom it booted, then went back added the old ram and it booted again. Thanks again for the help.
