Does RAM Timings Affect Performance?
Does RAM Timings Affect Performance?
I checked the availability of the RAM models you mentioned. The version with 16-20-20-38 is currently out of stock, while the 16-18-18-36 model is in stock. For your i9-9900k processor, you might want to consider the timing differences between these options. If the faster timing RAM isn't back soon, purchasing the slower one could be a safe choice. You can find more details via the provided links.
The variation in the XMP profile for the RAM you're checking is minimal, so it likely won't affect things unless you decide to adjust it yourself.
I meant the 16-18-18-36 sequence. I wasn't sure about the timing, but I assumed it was because the numbers are smaller the car runs more slowly.
