Crucial Ballistix MAX RGB 4000 MHz DDR4 DRAM Desktop Gaming Memory Kit 32GB (16GBx2) CL18

Right out of the packaging this RAM looks really nice in my hands. Good shape, the heatspreaders are solid and the sticks have a low profile clearance. Very attractive and looks great inside my case. RAM clicked right into the slots with no issues.Turning on my computer, I POSTed and went right to my desktop. Nice! Default RGB is a rainbow wave that looks pretty cool. Quite bright and vibrant but not overly so, just perfect imo. LED's are spread out nicely. I decided to change the RGB's using MSI's MysticLight software. No issues there, settings worked perfectly and stayed after reboot.To get the speed advertised I booted into the bios and enabled my XMP profile (using an MSI B450 Tomahawk Max MOBO, for reference). I went to POST with no issues and it ran 3200MHz CL16 timings, as advertised. Did some MemTest64 for about 15 minutes, zero errors👍Happy with the timings and speed but still curious I decided to do some manual overclocking. This essentially consists of going beyond the advertised speeds by adjusting frequency and tightening the timings in the BIOS manually instead of using a default XMP profile. Wow, I was impressed. For reference here, I am using a Ryzen 5 3600.These sticks of RAM are Micron E-die, known to have great overclocking potential and be of excellent bin quality (its good silicon). With this processor and my aforementioned mobo, I was able to actually achieve 3600MHz and CL15 timings and speed 100% stable! This is with only 1.39V as well. Quite impressive IMO! Zero errors on the MemTest again. Insane value considering the premium price of comparable 3600 MHz sticks (usually coming with worse timings too). Im confident with more voltage I could even achieve CL14 stable, but im quite happy with this.I've included a picture of the RAM in my system and my current timings/frequency. In the CPU-Z picture, note that because it's DDR RAM (double data rate) we multiply that figure by two to get 3600MHz.With this overclocking potential and the beauty of the RGB and design, this RAM is an unbelievable value and a 10/10 choice. Whether you are a plug and play type or an overclocker, I highly encourage you to purchase this. Fast RAM for a gaming rig or any kind of productivity with a great price. Great product Crucial!PS: Sorry my pictures aren't properly aligned!

XMP 2.0 instantly registers correctly on an MSI X470 Gaming Carbon Pro with a Ryzen 7 3700X.I used DRAM CALCULATOR and tweaked the timing tighter to 16-16-16-36 (CL-RCD-RP-RAS) on 1.3V and these are the best performing DRAM modules I have ever owned - HANDS DOWN.They are at least as good (if not better) than Samsung B-die and are high quality Micron released in week 20 of 2020 and can keep up with any Ryzen 7/9 on any X470/X570/B550/B450 platform.Temps stay really low. Great quality heat sinks, and Crucial has an app that will turn on any color of the rainbow. I use their app to turn off the RGB completely (which is what you will need to install if you want to turn off the RGB). I did not use the RGB. It come on pulsating by default.This is the most reliable DDR4 3600 DRAM you can get for the price as of Fall/2020. The reason it is out of stock all the time is because it does exactly what it says it will do and is rock steady DRAM at the advertised speeds. Very easy to O/C this dram, but recommend at least the X470/X570/B550 VRMs for O/C.FAST! on the Ryzen 3700X @ 4.3Ghz

Want low profile RAM? Want it in RGB? Here you go. This memory is barely taller than the Corsair LPX and the difference isnt even noticeable. So if you have something like a Noctua NH-D15 and want some glow this is your memory. The colors fluctuate between solid colors stock setting instead of a rainbow effect. You'll need crucial software to change this effectUnfortunately this RAM didn't play well with my wife's Ryzen 3600 and X570 board. For one it wouldn't boot with both sticks and couldn't hold an XMP overclock. I tested them on my 8700K build they worked as advertised. Unfortunately I already have good Samsung B-die memory for that build while these Crucial sticks were for my wife's Ryzen build. So I had to return them. Were I looking for low profile RGB memory at an affordable price I would snatch em again up in a heartbeat

RGB is bright, installed easily, both sticks worked, have an H470 board so RAM is speed limited anyway. It is speed limited to (I think) 2933, but My mobo is only able to run these at 2600ish without POSTing in safe mode. I'm not sure if this is a RAM or mobo issue. I don't really care because I'm not going to notice a difference anyway.Maybe this is an uninformed complaint, but the RGB control software (MOD) does not "save" your settings to the ram sticks. Maybe all RAM RGB control works this way, but it would be nice if you could open the program, set the rgb, then never have the program open again (disable it at startup) until you wanted to change the RGB pattern again. I don't like extra crap running in the background, so this would be great, but like I said maybe this is just how RAM RGB works. It does default to a rainbow pattern, which is fine, and I have a perforated non-glass case (NR200P) so the pattern is subtle anyway but I guess just an FYI. A related positive, the MOD software is very lightweight and not a bloated disaster like most similar software, so that's pretty awesome!
