December 2020 (updated review) > my original review from August 2020 is at the bottom of this thread.
<<I have been using this pair of DIMMs while overclocking my CPU to 5.1GHz / 5.2GHz for days now and I can confirm that I have had no issues with them over the last 4 months, as far as functionality. I have noticed that under heavy CPU stability test (Aida64 / Prima95 / Intel Burn / LinpackExtreme), with CPU temperatures going up to 95 / 97 Celsius at 100% full load on all cores for hours, the RGBs lights at times dim, or shut off altogether but then come back to life after the stability tests are completed. I can't tell whether this is a case isolated to this specific model (I really doubt it) or whether the PCB's circuitry and/or RAMs' slots have something to do with the RGB lights' unusual behavior, specifically given the high voltages and heat injected into the circuitry and MOBO. This may be a PCB issue, rather than a RAM issue. When you stress test a CPU at full load and at 92+ degrees for hours, anything is possible. I have not modified the 'Cl' timings, though, or the voltages fed to the RAMs via UEFI.
I will try to overclock these RAMs to over 3600 again (starting from 3800MHz), along with CPU OC, and see where that leads. I am not sure it's safe in terms of RAMs' degradation to keep any RAM at higher XMP than advertised / tested by the RAM's OEM, however. I tried overclocking these RAMs to over 4000MHz - but only for a brief period of time - and then eventually reverted back to 3600MHz in XPM. It worked then. Do not attempt anything over 3600MHz in XMP, if so advertised by the OEM, unless you are adventurous / understand the overall implications of higher V loads / dose the higher V loads accurately and are willing to take that risk.
Finally, I purchased these RAMs to pair them with a 10th gen Intel CPU with Z490 chipset. These are NOT designed for laptops, MacPro notebooks, or even most of the generic HP / Dell desktops. I get a lot of questions on Amazon about using these RAMs with laptops/HP, Dell desktops. These are overclockers' RAMs. I tested them with the most 'extreme' overclocking settings and temperatures for over 150 hours in a short span. If not into OC, they're overkill, or altogether unusable because not supported at their full capabilities >>

I use the 3600MHz Kingston HyperX, dual channel, 2 DRAM sticks of 16GB each. My PC is even capable of running them at 4133MHz at very low CL (17-22-22-38), very stable. MemTest provides clean, error-free results! I'll run them at the advertised 3600Mhz frequency, but apparently they give you much more than what you need, unless I just got lucky with these, or know how to overclock well: I spend hours tweaking and adjusting voltages and different values, based on basic principles of electrical engineering. So far, no complaints... I hope they last (at the advertised speed of 3600Mhz).
One suggestion to the end-users, before buying RAMs: Make sure that the configuration and frequencies match the QVL from your motherboard. I wanted to purchase G.Skill Trident RAMs because of the cool-looking RGB lights, but these were the only set of 16BG X2 at 3600Mhz that looked compatible with my motherboard, so I followed the QVL suggestion. The RGB lights on these RAMs are actually surprisingly very cool. So far, I am very happy with my purchase. I might consider buying a higher frequency set when the motherboard's QVL is updated, even though right now I enjoy these RAMs and they give me more than I need.
