1st Time PC Builder Ram Problems

[jdmccarter8]

I am a first time PC builder and thought I had done all of my research but it seems that my ram isn't compatible with my mobo. Everything else works fine but my 3200 mhz kit is only running at 2133 mhz because when I try to enable the XMP 2.0 profile, I get a blue screen saying my PC needs maintenance or something similar. I then I have to use the Clear CMOS button and then I'm back to the 2133 mhz. The Corsair Ram Kit is Intel Compatible according to their website and my CPU is a Ryzen 7 3700X. So my question is, is there a way for me to manually change the RAM settings to allow me to use the full speed of the RAM or am I stuck because it's not compatible?

 

Thanks!

When you choose the XMP profile in BIOS does it say DDR4-3200 16-18-18-36 1.35V? Also, are your BIOS updated to the latest version?

I am on the newest BIOS, Ver. 2.10. When I choose the XMP profile it does change the speed to DDR4-3200. I'm not exactly sure what the timings and voltage get set to when I choose XMP 2.0. But, when I reboot the system, I get blue screened.

You might want to check your motherboard's QVL for compatible RAM. If your model isn't listed there, it may just be that particular kit isn't compatible with your motherboard/cpu combo. Personally, if XMP isn't working, I'd probably return it and get a kit that's listed on the QVL. You should be able to find it on AsRock's website. Just look up your board, click on support, and you should be able to find the compatibility list.

Yeah my kit is not on the x570 Taichi QVL list. I was hoping there was a way to manually change settings and get the kit to run at 3200 instead of having to get a different one.

You might be able to get it running at different settings, but it gets pretty complicated. I just finished memory overclocking on Ryzen and it took me almost a whole week. The best advice I could give if you're going to go that route is to download Thaiphoon Burner to find out what die type your memory is (Samsung B-Die, Micron E-Die, etc.). Then download DRAM Calculator, punch in your memory information, and then make the changes to the settings it churns out for you. That was the most helpful for me. I had a 3866mhz 18-19-19-39 kit that I down clocked to 3733mhz 15-16-14-28. I probably wouldn't have been able to get a stable clock going without those two programs. You have your speed and main timings which are pretty easy for the most part. You have to match your memory speed with your infinity fabric. Since it's "double data rate" memory you'd divide the memory speed by 2, which in my case, the infinity fabric ended up being 1867mhz to match the ram. Then you have to worry about sub-timings which is where it really gets difficult. That's where DRAM Calculator really shines. And don't forget about voltages and other power regulation settings.

 

If you're just looking to quickly set XMP settings, it would probably be easier to return that kit and just buy a new one on the QVL list. Otherwise, you're going to have to go down the rabbit hole that is memory overclocking. Although maybe in your case you could just reduce the memory speed or increase the DRAM voltage if you don't want to worry about timings too much.

Thanks! I will try this out!

Good luck! And make sure you know where the clear cmos jumper on the motherboard is.

I finally got around to messing with all the timings and your help was invaluable! I got the kit running at 3200mhz and all is well! 

 

Thanks again Vortex88
