So I made this thread a couple of days ago.
Again, MOBO is B450M-A
One kit of 2x4gb Kingston and one kit of 2x4gb Adata (Summing up 16gb)
CPU is Ryzen 3200g.
After trying almost everything, I had lost any remaining hope, but suddenly a solution came about unexpectedly.
On the BIOS I went to advanced > AMD Overclock > DRAM Timing overclock
And switched DRAM Frequency from AUTO to 1333 MHz
However, on the Ai Tweak options I manually set it to 2400MHz, because I already knew that whenever I put 2666MHz on Ai Tweak while all 4 ram slots are being used, my PC just wouldn't boot. Yes, even if I put the DRAM voltage to near 1.4v even If I loosened the timings.
So all I did was that and OC a little bit my CPU an iGPU (CPU on 3.7GHz, GPU on 600MHz), increase the DRAM voltage a little from 1.20v to 1.25v, just in case it might help.
I exit the BIOS, turn off pc, install the remaining 2 rams, boot PC normally, enter task manager and go to memory, and it says memory is working at 2666mhz. ALL 4 STICKS. Same in CPU-Z.
I was, and I still am, astonished.
My theory is I tricked the BIOS out of some compatibility issue (perhaps related to the Daisy Chain topology and/or even the different RAM kits) making it think I'm running the RAM at 2400mhz when I'm actually telling the IMC to do the job the BIOS can't do properly (making the RAM run at a certain speed).
Now I'm just afraid of entering the BIOS, touching something and going back to 2400mhz... So what I basically want to know is if this
[Advanced > AMD Overclock > DRAM Timing overclock > DRAM Frequency 1333 MHz] is what did the trick. I'm a little new to all of this so I will thoroughly appreciate any 'for dummies' explanation.
[SOLVED] - Can't get 4 DIMMs running at 2666MHz on B450M-A
I have two Kingston 4GB 2666MHz and two Adata 4GB 2666MHz, and am going for quad-channel. My MOBO is an Asus B450M-A. CPU is Ryzen 3 3200G with stock cooler. Everything is brand-new. I tried all sorts of combinations for the DIMM slots, always after a CMOS reset, but no matter how I did it, I...
