Pros: Great ram. If you're on AMD and can't get over 3200mhz, it's probably not the memory at fault. See below.
Cons: Other brands like Corsair have an easy to find guide on setting their ram up for Ryzen. I found Patriots competitors guides to be helpful in this case.
Overall Review: Ryzen 3600 Asus Tuf Gaming x570 This was the most challenging experience with setting up DRAM I've ever had. I knew what I was getting into with non-qvl sticks but I was hoping I'd get lucky. Default speed was 2133 mhz on setup - ok Used the timing calculator to try and hit 4,000 - not a chance even at 1.5v. Also learned from forums that 3800mhz with tighter timings is preferable to 4400mhz Found out DOCP = XMP. - couldn't break 3000mhz Found out people with this board have had issues with memory speeds in the A0 B0 slots - switched and could hit 3400 mhz with errors in memtest86. Hopefully a bios update will fix. Used Corsairs PDF for Ryzen memory and found out that 1T and gear down mode OFF can cause instability - and instability it did. 3800mhz on 2T with gear down mode ON no errors. Also used ProcODT of 48 as suggested by the guide. Went for tighter timings like CAS latency 14 - No luck on 14. Final settings with 0 errors on a full memtest86 run are as follows: Use the 1.45v XMP profile. Set to 3800mhz. FLCK auto (1800mhz). Now 15 15 15 15 34 50 for the first 6 settings. ProcODT - 48ohms, Cmd2T - 1T, Gear Down - Enabled. All others on auto.
Pros: This memory is a beast. I was able to get it to 4400Mhz HOWEVER Performance is not real good because of loose timings and how Ryzen handles anything over 3733. Best setup that these work with is Set your FCLK to 1900 Mhz and your memory to 3800Mhz Then set the Memory voltage to 1.5 volts and you can get CL14 timings which will out-perform 4400Mhz on a Ryzen system. If that makes you nervous you can set the voltage to 1.45 volts and set it to CL16 timings at 3800Mhz which will still out perform 4400Mhz. One thing to note I have now purchased 3 pairs of these and I got all three to work exactly the same way and I purchased them 6 months apart so this is not a fluke in the timings that I am saying and I got it to work on an ASUS x470 and an ASUS x570 motherboard with the same timings. Use the Ryzen DRAM Calculator.
Cons: None
Overall Review: Works exactly as advertised
Pros: Was able to boot up XMP on the ASUS X570 ROG Crosshair VIII Hero with a 3800X. Runs 4400 Stable and passes Memtest86. Seriously Install the newest BIOS, set everything to defaults and enable XMP.... Not hard. Optimal results are 3800 CL 14-15-15-15-34-50 T1 @1.45v Passed Memtest86. I was also able to push it to 4500 before extra tweaking and care to the SOC / IF voltage was needed.
Cons: Nothing!
Overall Review: I see a lot of people complaining they can't go above 3600 or even 3200 on AMD. Well that is not the memory fault, it a combination of auto settings on the motherboard and CPU. Not all Ryzen 3000 chips can reach FLCK 1900. I would say 99% can do 1800 Mhz which matches DDR4 3600. So either you are buying this kit because you are trying to go for 3800 CL14 on AMD or you are a Intel user. Don't complain that you cannot get this kit to boot above 3600 on AMD unless you know what you are talking about. Manually setting memory timing is a annoying, but anyone buying this kit should already know that anything above DDR4 3800 on Ryzen 3000 chips is counter-productive.
Pros: One of best RAM kits available for the price. I bought this knowing it would either max out or exceed my 9900k memory controller ability, hence no point in buying more expensive higher speed RAM than 4400.
Cons: Many current cpu memory controllers (intel ie 9900k, ryzen) cant do 4400 yet so requires setting speed/timings yourself if your cpu did not win silicon lottery for memory controllers. Future cpus from intel (10900k and rzyen 4000) should have higher percentage that can run this at rated speed.
Overall Review: One of the best RAM kits for the price. My 9900k's cpu memory controller wont post at 4400, will bench only 4266, 4133 will run memtest stable but only at high 1.4 vccio/vccsa volts. But 4000 rock stable for 8 hours memtest with reasonable 1.27 vccio/vccsa. Instead of stock 4400 19-19-19 at 1.45v, I was able to run 4000 17-17-17 and tight secondary timings with 1.4v dram, 1.27 vccio, 1.27 vccsa for 8 hours memtest stable. 4000 with tigher timings got nearly same aida64 speed with better latency vs 4266 C19 (secondary xmp setting). I tuned my kit by booting 4400k XMP (failed), then 4266 (booted but failed memtest in seconds), then 4133 (failed memtest until incremently raised VCCSA/VCCSI to 1.4 which is too high for my taste for 24/7). Settled on 4000 max for my cpu memory controller and then manually set volts to reasonable 24/7 of 1.4 dram, 1.27 vccio/vccsa. Then tightened primary timings to 18-18-18, ran memtest for 20mins, then to 17-17-17 passed. Tried 16-16-16 and 16-17-17 both failed. Then ran 17-17-17-37 which passed for 2 hours of memtest. Then booted at stock without xmp 2133 and wrote down all secondary timings and booted to xmp and wrote down all secondary timings. Then with 4000 set manually XMP off, voltage manually as above, was able to walk down secondary timings all close to or at 2133 level, left tertiary alone. Then memtest overnight 8 hours with 850% coverage no errors.
Pros: Solid memory with heat spreaders that are not too tall. I was able to overclock these quite a bit, awesome Samsung B-die memory works very well. I tried at various clock speeds using DRAM Calculator 1.7 (4000, 3866, 3733, 3600) and the best results for me were to set them at 3600MHz, CL14 at 1.38v. I followed all the DRAM Calculator settings for 'Fast' timings and it worked like a champ in my MSI X570 MPG Gaming motherboard. YMMV
Cons: Can't think of too many. Guess I wish it were cheaper, but not complaining for the performance I was able to achieve
Overall Review: Highly recommend, especially if you can get these on sale. Forget about using 4000MHz CL19 speeds. Even though that is fast, you can do better - much better. Start with that timing from the XMP profile, but then tune these to run much faster by doing some research online and put in some time to tune and test them. Worth it!
Pros: - This kit hits Diamond Standard for Ryzen 3800MHz 14-14-14-14-26 - B-die - Heat spreader looks nice aesthetically - Black/silver color - Lower profile - No RGB - Impressive performance 3800MHz cl14 62.3ns (AMD) - cost
Cons: - heat spreader a little cheap - packaging little cheap
Overall Review: This is high quality B-die. The performance has been unexpected. This kit hits the Diamond standard for Ryzen 3800MHz cl14. - AMD 3800x 4.4Ghz 1.3v, Asus Crosshair VII x470, 3800MHz 14-13-13-13-26-39-238 1.5v - 61.6ns, 57000wr, 54000cpy - AMD 2700x 4.35GHz 1.375v, Asus Crosshair VII Hero x470 3666MHz 14-14-14-14-26-238 I def recommend these for Ryzen builds...
Pros: price low timings
Cons: fragile radiator
Overall Review: So far this result has turned out: 3600MHz 16-15-15-15-30 CR1 1.37V, SOC 1.05V. AMD RyZen 5 3600 4.2GHz 1.2875V + MSI X370 GAMING PRO CARBON Bios 7A32v1NV. I will continue to try to lower the timings :) UP. The final result - 3800MHz 16-16-16-16-30 CR1 1.38V, SOC 1.075V. Everything is stable.

Pros: - Please read this review carefully before you decided to buy this product. - 4400Mhz is a very high frequency, no one can guarantee it will run XMP on any system. - Unbelievable price for 4400Mhz RAM, some 3200C14 RAM cost same as this one. - Pass memtest 1000% at 4400Mhz after some voltage tuning.
Cons: - This is not a RAM for beginner!!! Simply enable XMP is not enough. - Really Carefully choose CPU and MB for this RAM, otherwise it will not reach 4400Mhz.
Overall Review: - For Intel User - I personally use MSI Z390I edge and 8700K with this RAM - For CPU, I only recommend 8700K,8086K and 9900K/KS/KF, the IMC in those CPU normally have good quality to support RAM running 4400Mhz and above. - For Motherboard, very few motherboards are capable to run this memory. I only recommend ROG ROG MAXIMUS XI APEX/GENE, ROG ROG MAXIMUS X APEX, MSI Z370I GAMING PRO and MSI Z390I GAMING EDGE. Those motherboard are high-end board with 2 DIMM slot, maximum the chance for this RAM to work at 4400Mhz. - It is important to adjust CPU SA, CPU IO and DRAM voltage for RAM stability. I use 1.5V for CPU SA, 1.35V for CPU IO, and 1.5V for DRAM voltage. This can be a good base line if you want to minor adjust voltage for your system to achieve higher stability or performance. - For AMD User, - First and Second Gen Ryzen will not support 4400Mhz RAM. - Third Gen Ryzen with High End ITX motherboard that support 4600Mhz+ may support this RAM.
