    Do you know what would be cool.
    I video showing the best ram out of the box for each CPU no playing with overclocking and timings.
    Some ppl just want to know the best options out of the box with no playing around with things.

                Stop talking everyone. He's saying that if you put the latency in your BIOS . literally whats on the box of purchase. and youll get 20%. This is what ive been doing since Intel core 2 Quad and AM3+ motherboards. It'll do 90% of the charm

                  If you are lucky Samsung b-die @ 3600 1.35volts will just go 3800 @ 1.35 volts with the same timings. This depends on IF1800 or IF 1900. It really does not matter what speed or IF you have. It's the tightened RAM timings that give your Ryzen cpu its great in game fps. A 3800x IF1900/3800 (decent tightened timings) RAM 4.4GHz all core will hit 11800 time spy cpu score. Not bad for a cpu that is 100's less than a 9900ks.

                  Can't be bothered overclocking the RAM or want a good place to start tightening the timings, https://www.gskill.com/community/1502239313/1564640918/G.SKILL-Releases-Optimized-DDR4-3800-CL14-Memory-Kit-for-AMD-Ryzen-3000-&-X570-Platform

                          Hi, can I actually use my 2400 Mhz DDR4 RAM into my motherboard that says the supporting speed is 2667 - 4133 Mhz? Please help!

                              I've got the msi x570 a-pro, an amd ryzen 7 3800x and G.Skill Ripjaws V 3200 mhz dual(to be precise the "F4-3200C16D-32GVK") and changing anything about the ram, even just Enabling a-xmp, causes my pc to not even boot into the bios and i have to manually reset the bios.
                              What could be a cause? I figured first that my 430w power supply could be the reasen but I should be fine with a 430w atleast according to the bequiet power calculator.
                              When I installed the 2 ram sticks they were set to 2133 mhz and some timings changed according to the mhz speed, but I specifically bought that ram for their 3200mhz since that is pretty good.

                              In the table for supported ram sticks my specific ram isn't listed, is there a way to still get my ram to 3200 mhz like i'd like to?

                                @Seawolf1988 the bequiet calculator says it is atleast enough, since the 1060 doesn't have that high of a power consumption, but in a month i will look for a new psu and look then
                                I've also looked up the supported ram for my msi x570-a pro, and my exact g.skill ram isnt on that list. That list only shows the ram they tested though doesnt it? I guess since my ram atleast works it should be supported somehow

                                Erich Pelzer 430W PSU with a dedicated graphics card is definitely a bit on the low side of things

                                          Guys, sorry for the noob question, new builder here. Should I go for 16gb (2x8GB) (dual) ddr4 3600 CL16 G.Skill Trident Z Neo or Corsair VENGEANCE RGB PRO 32GB (4 x 8GB) DDR4 DRAM 3600MHz C18. Motherboard would be x570 Aorus Elite ryzen 5 3600 and 5700xt GPU. there's a $20 difference between vengeance pro and trident z. Both brand new. Would you go for the corsair 32GB CL18 RAM if there's only a $20 difference?

                                            The 4x corsair is better value.

                                            Ryzen only installs on Windows 10. For help https://community.amd.com/community/support-forums/general-discussion

                                            You can use a small screwdriver to put one rice-grain-size blob of thermal paste on the CPU near the center and it will cover the two or three areas where the processor dies are as the paste will spread out when the cooler is placed on it. Thermal paste was designed to fill in the tiny cracks between the heatspreader (CPU casing) and the cooler, not as a primary heat-transfer compound. Too much paste does more harm than good so it's not needed in the corners. Use the small screwdriver to straighten any bent pins too. Renew the paste every 12–18 months. See https://binged.it/2ZL6INa

                                            (If you get the 3600, 2600, 2200g, or 2400G the Wraith Stealth is a bad cooler. Try the Cooler Master 212 evo or the smaller Antec a40 pro. Thermal Grizzly Hydronaut is a very good paste.)

                                            A new Ryzen user wrote: “make sure windows 10 allocates enough space for virtual memory because my computer was stuttering for a while”. (I think they mean the page file/swap file. It really means they didn't do so with their old processor.)

                                            “My ONLY point of frustration came from some instability I experienced that took me a while to troubleshoot, first thinking it was probably some sort of memory incompatibility. It ended up being an incompatibility with the Windows 10 Ryzen power plan that was installed. Switched to the regular "Performance" plan and its been rock solid ever since.”

                                            If the processor idles at a high temperature: in the BIOS disable all 3 options for Precision Boost Overdrive (PBO). Set Windows Power Plan (not AMD's one) for "Balanced".

                                          is it better to buy a G-skill 16GB( 2x8 ) 3600Mhz ( f43600C16D-16GVK )B-Die or a G.skill Flair X ( 3200Mhz ) cause of 14/14/14/34?

                                              I think that it's interesting that the by the looks of it the max difference between a 3200 CL14 without tampering with FCLK and 3800 CL18 FCLK1900 is in metro exodus, coming in at 8 fps. In all the other tests it is 1-3 fps difference. So to sum it all up, go for the cheapest of the follwoing; 3200 CL14, 3600Cl15, 3800CL16 if you want max or near max performance. 3600cl14 is also available, but atm extremely expensive, i could only find the "G.Skill G.Skill TridentZ Neo DDR4 3600MHz C14" which here cost 235% more than the 3200CL14 ram from Gskill, this would at best give a 5% fps increase in metro exodus.

                                                            P.S. Linus, I don't mean to poop on you by quoting you here. It just helps to convey what I am referring to in the video. I've got nothing but love for ya <3!

                                                            My thoughts:
                                                            - According to the stats in the video, contrary to what Linus said, you may not be "getting darn near the full experience" (8:07) by using a 2133 OC as a 3800 OC seems to offer noticeably better performance (which I know is subjective).
                                                            - If you are tightening the timings from 3800 CL16 to 3800 OC and getting "holy shmoly" (6:14) performance, I think it's safe to say that faster RAM (based on both MHz and CL) will yield better performance.
                                                            - Regardless of the RAM you have, crank FCLK as much as possible. Then, the faster the RAM (based on both MHz and CL), the better the performance.

                                                            Based on these stats for SOTTR with FCLK 1900:
                                                            - At time 4:06, FCLK 1900, DDR4 2133 OC, FPS 87, 135
                                                            - At time 6:13, FCLK 1900, DDR4 3800 CL16, FPS 87, 136
                                                            (similar to above DDR4 2133 OC)
                                                            - At time 6:13, FCLK 1900, DDR4 3800 OC, FPS 106, 149

                                                            Observations:
                                                            - For the same FCLK (in this case FCLK1900),
                                                            - DDR4 3800 OC > DDR4 3800 CL16 = DDR4 2133 OC
                                                            - In other words, for the same FCLK (in this case FCLK1900),
                                                            - DDR4 3800 CL16 performs similar to DDR4 2133 OC.
                                                            - DDR4 3800 OC performs better than DDR4 2133 OC.

                                                            Conclusions:
                                                            - For the same FCLK, faster RAM (based on both MHz and CL) will yield better overall performance.

                                                            Implications:
                                                            - Regardless of the RAM you have, crank FCLK as much as possible. Then, the faster the RAM (based on both MHz and CL), the better the performance.

                                                            Can anyone correct me if I'm wrong?

                                                            P.S. again: Since 3800 CL16 performs similarly to 2133 OC, we can predict what CL timing the 2133 OC was tightened down to. Using CL/MHz*2000 to calculate total latency in nanoseconds (ns), 3800 CL16 has a total latency of 8.42ns. Since 3800 CL16 performs similarly to 2133 OC, we can plug in the 8.42ns into the equation, rearrange for CL, and we get CL8.97, rounded up to CL9. Therefore, the 2133 OC used in this video was tightened down to CL9. Correct me if I'm wrong :).

                                                                      If you run 1:1 using the base clock of your RAM and matching the infinity fabric speed, (2400 RAM and 1200 IF, for example) you will get a very stable performance that will improve as you reach higher RAM speeds. If you go over/under the 1:1 ratio, then make sure to adjust your RAM timing to compensate for latency.

                                                                            I'm about to get MSI B450 TOMAHAWK MAX and Ryzen 5 3600. What (2x8GB) RAM would work the best with these two?

So I looked and found that the limiting factor isn't the board itself, but the CPU ICM. So I thought sweet, I can run 3600mhz with that motherboard. But then I checked the AMD website, which says Ryzen's maximum memory frequency is 3200mhz. I am confused, can anybody help?
