Best RAM for my setup?
Best RAM for my setup?
Hi, today I own Corsair Vengeance LPX Black 64GB (2x32GB) DDR4 / CL16 / 3200 MHz / DDR4 SDRAM (CMK64GX4M2E3200C16). I’m curious about improving performance by switching to faster RAM like 4000MHz or 4400MHz with better timings. A 64GB capacity is sufficient, and I have two 16GB modules in four slots, leaving room for future upgrades. My system uses an MSI Meg Z490 Ace with an i9 10900k processor and a 2080 Super graphics card.
with intel depending on cpu core overclocks you actually want to be with ddr4 4000+ If you dont do manual overclocking you are fine with that dirt 3200 cl16 kit. But if you increase your CPUs core clock each step requires more bandwidth. 5ghz is fine with ddr4 3600, 5,2ghz is fine with ddr4 4000 Bandwidth / latency performance always scales linear unless you are bandwidth bottlenecked.. If you have faster ram your CPU will become faster depending on how well the application you use it for can utilize cache. If a CPU spends 50% of it's time waiting on ram, and you make the ram 50% faster then the CPU will become 1/(.5+.5*.5)= 1.333 times faster. If it spends 10% of it's time waiting, then the speed up is 1/(.9+.1*.5)= 1.05 times faster. The benefit is always positive, but depending how well the application can use cache, it may be large or small. This is scientifically proven since 1988 and is called Gustafson's law. https://en.wikipedia.org/wiki/Gustafson's_law Ignore plebs that dont know it better. Fortunately you can get ddr4 4000 cl15 kits nowdays, a year ago this wasnt actually even that easy to get from manual OC, so if you are overclocking your CPU i recommend looking into a 3600cl14 kit atleast with manual overclocking, or buying the expansive 4000cl15 kit if you want enough to not worry about and tweak a little.
Find benchmarks on YouTube about how popular apps perform under different memory speeds. If you mainly use your PC for gaming, your FPS might improve a lot if you play CPU-heavy titles. Based on the game, resolution, and graphics settings, you can boost performance with quicker RAM.
I support this product: CMK32GX4M2F4000C19 https://www.corsair.com/eu/en/Categories...M2F4000C19 Perhaps I'll choose the CMK16GX4M2K4000C19 since it's similar but offers 2x8GB instead. If I purchase four 8GB units, I could save 100 euros compared to buying two 16GB sticks. Is this a solid RAM configuration? Right now I own: CMK64GX4M2E3200C16 https://www.webhallen.com/se/product/311...M2E3200C16 The 3200GHz models have CL16 while the 4000MHz ones have CL19.
For RAM verification focus on RAM QVL rather than board QVL. Listings for Board QVL tend to be less precise and omit confirmation that RAM operates at its advertised rate. Consider checking the G.Skill F4-4000C15Q-32GTZR.
