Consider target RAM speeds based on your system needs.
Hey everyone, I'm trying to build a new PC in a short time and want everything to work perfectly. I've been learning about latency lately, but it's still hard to grasp. It seems speed is more important than low latency, yet finding the best balance is ideal. (From an important article) So, I'm thinking about buying the Corsair Vengeance Pro RGB. My choices are: 3600 - 18 - 22 - 22 - 42, 3200 - 16 - 18 - 18 - 36, and 3000 - 15 - 17 - 17 - 35. All three options cost the same. Do they really differ much in performance? I checked Reddit and found a chart—everything looked pretty similar, scoring around 10. I'm hoping to pair it with a Zen 3 CPU when it comes out.
The faster the RAM clock speed, the greater the impact on performance, especially when considering the interface latency. For every nanosecond of delay, you can expect a performance boost of roughly 0.5% to 1%. I’m not sure how important RGB is for your setup, but the Crucial kits are worth considering because they can be easily upgraded to higher speeds. They don’t match Samsung B-die in latency, but they’re usually more affordable and simpler to obtain. I’m unsure about specific Corsair models using Micron E-dies, but that’s something to look into further.
lower timed chips might be rounded down more, yet delay remains the same for all three. Basic memory latency calculator https://notkyon.moe/ram-latency.htm
Well, initially it's important to note that when listed with speeds like 18-22-22-42, the data refers to timing rather than delay. Delay measures how long actions take, whereas timing indicates how many cycles are required. For example, a 3600 CL 18 sequence completes in fewer cycles than a 3000 CL 18 one, since the 18 cycles finish quicker. If all achieve identical delays, the faster rate is better overall.
I've been influenced by these suggestions and prefer that RAM, even though I want top performance. I'll have to compromise on some features for the one I like. Thanks for the insight! The calculator matches the numbers from that Reddit thread. I believe 3600 would be ideal. I considered it carefully just to confirm.
