Checking RAM response time Query about RAM latency
I’m considering replacing my RAM and have a preference for the Corsair 32GB (4x8GB) DDR4 Vengeance RGB Pro SL C18 3600Mhz model. I’m unsure if the timing specifications are suitable. My system runs a Ryzen 5 3600X B-450M Tomahawk (likely the Gigabyte variant). For context, the current RAM timings are 18-22-22-42.
The schedule averages out. 3600 CL18 is normal, 3600 CL16 is solid. But I’d be careful using four sticks at 3600 speed with a 3000 series Ryzen. It usually works, though sometimes the memory controller gets strained. DDR4-3600 is reliable about 99% of the time with two sticks, but four might push it a bit too far. Overall, the chances are still on your side, just remember it’s not a certainty.
These clock speeds are average, not the worst I've encountered yet, but close to it. Typically you should steer clear of Vengeance RAM (especially for DDR4) because it's costly for performance and has poor binning for dimensions. Unless you're particularly drawn to its appearance and only have a strong interest in looks, opt for Trident Z instead, ideally at 3600MHz CL16.
I can operate at lower frequencies, as low as 3200mhz. I’m currently running it, and I’d like to know if that would be effective.
With 3200 speed RAM, the main purpose of upgrading might be performance rather than appearance.
You're focusing on improving your setup for better performance and a more enjoyable experience. It's great you're considering 32GB RAM for modeling work. Just keep an eye on how the games affect your system—high visuals shouldn't come at the cost of stability. Enjoy the process!
Higher RAM speed can boost performance when timings match or improve. If your RAM is DDR4-3200 CL16 or slower, upgrading to DDR4-3600 CL18 still offers a benefit since 3200 CL16 and 3600 CL18 share the same CAS latency. Clock cycles are measured in cycles, so at 1800MHz DDR4-3600 completes its 18 cycles in 10ns, while 1600MHz DDR4-3200 also takes 10ns for 16 cycles. The difference lies in bandwidth, which is enhanced with the faster speed. Usually, performance gains from memory bandwidth aren't huge, but some apps might see improvements. If you prioritize speed and can afford it, upgrading to DDR4-3600 is a smart move. Regarding running multiple sticks at that rate, I didn’t intend to discourage you—just wanted to let you know there’s a small risk if your CPU or board isn’t suited for it. The chances are favorable, but I wouldn’t suggest it without considering possible hiccups.
