G.SKILL TridentZ RGB Series, 32GB (2 x 16GB) 288-Pin DDR4-3200MHz CL14 Desktop Memory

Running two kits (64GB) on Gigabyte X570 Master. Enabling XMP ran a single kit at advertised speed and timings as expected, but didn’t perform any better than an inexpensive 3200 CL16 kit. You really need to push the speed to 3600-3800 and manually tune timings to realize the performance this memory offers.Make sure your Infinity Fabric FCLK matches memory frequency, e.g. for DDR4 3800, FCLK must be set manually to 1900 Mhz. A single kit of this G.Skill would only overclock in the DIMM slot furtherest from the CPU socket. Not unexpected for a daisychain memory layout.After an hour of tuning, I got a single kit running at DDR 3800 16-16-16-32, tRC 48, tRFC 294, 1T at 1.38V and 1900 FCLK. These setting measured 64.0ns latency in Aida64 and reached max theoretical memory bandwidth. Attempts to reduce timing latency further didn’t improve performance, so I stopped here. I believe ~64ns and 60GB/s is about limit of the Ryzen 3000 platform.I didn’t expect the system to POST when I installed the second kit into the remaining two DIMM slots. But to my surprise and delight, it did. All four sticks installed (64gb) performed about the same as a single kit (32gb) and passed all four passes of MemTest. Stability seems good in Win10 too.In summary, this kit is VERY expensive and probably unnecessary. Benchmark scores improved only a few percentage points. But if you insist on running the absolute fastest RAM in your system, the famously overclockable Samsung B-die delivered the goods for me. I plan to take these sticks along with me to run on a future upgrade to Threadripper, so viewing this as a long term investment.

I’ve built many computers for myself and friends, but never had a problem that new RAM solved. I ran a 6700K with a 980TI using 2x16GB G.Skill 3200MHz CL18 that I purchased in 2016. I upgraded my processor to the 7700K and 8700k and my GPU to the 1080, 1080 TI, and 3080 over the years using the same RAM and never had a problem until I bought the 11900K with my 3080. I bought a used 360hz monitor and figured I’d have no problem getting 360+ fps on Overwatch since my previous build with the 8700K and 1080TI got 300+ fps on that game. To my surprise I was getting 230 fps average in Overwatch on my 11900K and 3080 which is way worse than my old build. I’ve been confused and frustrated for the past 6 months troubleshooting this. I got some tips that it was my RAM so I tried some 4000 MHz CL19 Patriot RAM and had the same issue with crashing. I tried G.Skill CL18 3600MHz RAM and had the same issue. I think that RAM was still a few model years old though. I came across this and saw it advertised it as “Made for the Z590 and newer chipsets” or something along those lines and the Z590 is exactly what I had. I bought this RAM and now I’m getting 370+ fps in Overwatch out of the box. Never thought a RAM upgrade was necessary until this moment. If you have 3-5 year old RAM you should probably upgrade. Also timings seem to make a bigger difference than clock speeds. Im not sure if this RAM is better just because of timings or if it is because it is newer manufacturing than my old set. It’s still DDR4 so I’d imagine there isn’t any architectural differences between old and new DDR4. Some extra information. I did play other games without problems on my old RAM. The most demanding thing I played was Guardians of the Galaxy. My computer had no problem playing it. It seems RAM plays a bigger part on low graphics-high fps games than high graphics-low fps games.

I've put these kits on a variety of AMD 500 series MBs but I know they work with 400 series too, at least part of them, and they always work by setting the XMP profile. I imagine if you set memory to manual timing you could adjust the tertiary timings to get a little better performance, but I just don't bother because I think you're likely to get more years out of them running on what gets set from XMP.For AMD Ryzen, Zen+ - Zen 3 (2nd - 4th gen) these are about the best it gets IMO. For Zen+ this is really about the fastest you can push the memory controller, for Zen 2 and Zen 3 you can run the controller at 3600 and it will be OK and most 400 - 500 series MBs will run 3600 no problem, but you start getting into temperature issues in my experience. These CPUs have to balance different metrics to determine how fast the cores can run, and when you run the memory controller at 1800MHz (3600mt/s), the infinity fabric needs to run at the same speed. This means the chiplet that deals with the memory controller and input/output for the CPU (IOD) is running at a higher temperature and using more power. The CPU has a TOTAL power limit and TOTAL heat limit, so when the IOD is running hotter and using more power there is less capacity for the cores, and this affects some models of Ryzen more than others. There are some models that can still push the cores to higher clock speeds and others can't.In other words, running 3200 CL14 and especially this kit which has great timings at 14-14-14-34 is a really good balance. You get really good memory timings but don't consume too much power for the memory controller and the infinity fabric and memory controller are running at 1600MHz instead of 1800 for 3600 memory. The IOD doesn't get as hot and doesn't consume as much power and the cores can then be pushed to their limit. But the other issue is heat and power consumption in general. If you have a room where the temperature is 76+ F, you probably don't want to run 3600 memory at ALL and then this kit becomes the best you can get.So after all that, I find these to be the best you can get without having to worry about the MB, specific CPU and how warm the room is the desktop computer is in.For Intel based systems, I got nothing for you. I don't use Intel so I can't give detailed information but in general the same pattern is true. The faster the memory kit, the more heat is generated and more power is consumed and at some point it will start affecting how fast the cores can run. But Intel CPUs can consume more power in general.

So far I’m having stable performance and problem booting up into the BIOS or booting into windows. Enabled XMP with no problems. No tuning just plug in play. Love it! Love the appearance as well. Black in the front and sliver on the back. Very nice G.skill.
