Issue with DDR4 memory response time delays
Issue with DDR4 memory response time delays
You have a 2x8GB Corsair Vengeance RGB Pro with 3600MHz CAS latency and 1.35V. It's functioning properly. Switching to a kit with CAS 16-19-19-36 would require adjusting for slower latencies. Overclocking your current setup to match those timings is challenging but possible. Running both kits at CL17 or even C18 would depend on compatibility and stability. Let me know if you need more details!
Unless you're using a quad channel setup, achieving the performance of the lowest-rated unit won't be feasible. Adding more memory and sticks per channel increases CPU strain and slows down operation. Manual adjustments to timing settings can help, but it's far from simple or straightforward.
If the timing varies, it doesn't mean they're identical kits. It's better to purchase the exact same one rather than mixing RAM.
It's late for that joke, but I messed up by ordering the CL16 version instead of the CL18. I thought only the CL18 was available, but now I'm learning from the experience. I'm based in Ireland and ordered from the UK, which means I have to send it back after Brexit complications. Thanks for the reminder!
Using the same kit isn't reliable; only guaranteeing stability comes from a double-capacity set. That means one kit at a time.
Using XMP doesn't always ensure compatibility. However, they should function together at the slowest timing settings you choose manually. You might need to adjust the settings between 3600Mhz and a range of 18-22-22-42. There are many secondary and tertiary timing options that may not work well with different hardware. These can often be configured per channel—if the above doesn<|pad|>, try matching sticks in the same channel.
