AMD Ryzen Compatible Memory List

From my own testing experiences which is now pretty extensive testing boards from 2 different manufacturers I can say that if you want to play things as "safe" as possible make sure the memory you buy uses Samsung B-die ICs, and is CL14 or 15. If you are lucky, you will get 3200MHz off the bat, if you are unlucky, you should still get at least 2933MHz with some very nice timings. In a twist of irony, steer away from the "geared for AM4" FlareX modules and instead buy some TridentZ or RipjawsV kits.

That might be a case of the Silicon Lottery effect, as you said. Does that other guy have the same CPU OC that you do? Same CPU?

I wonder if the lottery effect can apply to memory too. The memory chips are binned to work at least at the highest OC speed, but there must be some +/- for each memory chip I imagine. All it would take is say one of the memory chips on a DIMM to not be as good as the others, just barely into its bin level, and it limits the speed of all the memory. How could we ever know if that is true?

Say that guy let you try his memory, I wonder what would happen. Or let him try your memory and see if it will work at his speed and timing settings.

If he could run your memory at the higher speed and better timings, and you could not get his memory to work at those settings, then if all else is equal, it would seem the memory controller is not as good in your CPU.

After looking at both the AMD list of supported memory and the ASROCK site, it doesnt seem to appear on the list. Could this be the issue i am having? The person who i bought the computer from said he took the memory out of an intel build just to get the computer going. I have the ASRock x370 Killer & Ryzen 5 1600X

make sure the two sticks are placed in slots
a2 and b2

make sure both sticks are firmly6 and fully pushed into the socket
it is very easy NOT to have them seated correctly

this is usually the issue

Can someone confirm that the Corsair Vengeance LPX would  work with the Fatal1ty AB350 Gaming-ITX/ac board

Thanks.

ON RYZEN ONLY USE DUAL CHANNEL NOT 2*SINGLE

ON THREADRIPPR ONLY USE QUAD CHANNEL NOT 2*DUAL


inside ram,(hardware ,IC and pcb )single,dual,quad not same ,completly diffrante ,, many people think = dual =2*single channel ram or quad =4* dual ram



you must use only ram, write on box QUAD for threadripper (dual for ryzen)

if you put wrong ram your system cant start , even if start , hiccops rip in windows, harm your cpu

in amd thteadripper ,change your ram to this
gskill ri4*8 3200=250$
or
gskil ripjaws4 4*4 2400=150$

www.amazon.com/G-Skill-Ripjaws-2400MHz-PC4-19200-Channel/dp/B00N1OZDPO

for ryzen use only ram write on box DUAL CHANNEL
gskill RGB trident z 3200 2*8 =180$
geil evo x 3200 2*8 =120$


not , only use 2400 or 3200 (best frequency stable) not 3000mhz
