Processors

I recently switched from a 1600x to a 3700x. Update my bios, put the cpu in and... no booting, just a loop of turning On for a few seconds only to turn off again a few seconds later. It appears that I cannot boot the pc with all 4 modules of ram, as just using a single one works, no matter the slot I put it in. I tried reseating the ram, as well as trying to up the voltage in BIOS (was able to do that with the singular stick in) but no matter what, more than 1 stick of ram doesn't boot. They worked before so, I have no idea what's going on.

Components in question are:

Ryzen 7 3700x/Ryzen 5 1600x

B350m Pro4 (bios is 7.40)

2x8gb 3000mhz, 2x8gb 3200mhz of Corsair Vengeance

If only using one stick of RAM instead of 4 sticks to be able to boot up is a good indication that your RAM Set is not compatible with the new Ryzen 7 3700X.

Another factor in your RAM incompatibility is that you are using 2 different set of RAM sticks, 3000mhz & 3200mhz which is a no no for Ryzen processors.

Try using the 3200Mhz 2 RAM Sticks together and see if it boots up or not.  In BIOS you can change to speed from its SPD to 3200Mhz.

Go to ASRock Support and purchase RAM set from your motherboard's QVL LIST for the Matisse processor from here: https://www.asrock.com/MB/AMD/AB350M%20Pro4/index.asp#Memory

I wanna run them at 2800mhz so the sticks shouldn't be an issue. Besides, even if I use the same sticks it still doesn't boot, not with the 2 3000mhz, not with 2 3200mh.

Just to be sure I now tried to run the sets of two, and nope, still boot looping (would send an image but the limit is 3mb so it's not that easy)

When you updated the BIOS on your ASRock AB350M Pro4, did you first upgrade to the bridge BIOS version 7.00 before upgrading to the 7.40?

With the original CPU and four DIMMs boot into BIOS. Load BIOS optimized defaults, save and exit. Power down and swap the CPU.

Yes, I did update to 7.0, then 7.4 and now I updated to the new version 10. Something.

I will try to do that, but I just got 3 beeps from my motherboard after I updated the bios. Will need to check what that means

I just got it to boot with one 3000 in A2 and one 3200 in B2
