Video Description

Does RAM choice really matter for AMD Ryzen X3D CPU’s? In this video we are going to find out. In the "Is It Worth It?" series we’ve been helping you make the right choice by showing you just how much you can expect to increase performance with a drop-in upgrade. In this video, our focus will be on measuring the impact of memory speed, latency, rank and infinity fabric speed on AM5 based Ryzen X3D CPUs. In addition to showing you benchmarks across 10 games, I will also demystify the AM5 memory architecture, and show how the three core clocks impact system performance. And if you stick around, I will show you how to optimize your core clocks, something every AMD Ryzen CPU user will definitely not want to miss. --------------------------------------------------------------------------------------------------------------------------------------------------------------- Skool Community: https://www.skool.com/blackbird-pc-tech-4230/about?ref=67e6a7048d9540fe87cbdf1b69bd47f3 --------------------------------------------------------------------------------------------------------------------------------------------------------------- 25K Channel Giveaway Link: (InWin Prism + 9800X3D): https://www.youtube.com/post/UgkxafrC9kLkFHQ3U6ApDlQ5YXbwiVnv57hf --------------------------------------------------------------------------------------------------------------------------------------------------------------- Key Component Affiliate Links: G.Skill Trident Z5 Royal Neo DDR5-6000 CL28 32GBGB (2x16GB) - https://amzn.to/46zCVLW G.Skill Trident Z5 Royal Neo DDR5-6400 CL30 32GBGB (2x16GB) - https://amzn.to/46ozaKn G.Skill Trident Z5 Royal Neo DDR5-8000 CL38 32GBGB (2x16GB) - https://amzn.to/3IkDwZX G.Skill Trident Z5 Royal Neo DDR5-6000 CL30 64GBGB (2x32GB) - https://amzn.to/483HZum G.Skill Trident Z5 Neo RGB DDR5-6000 CL34 128GB (2x64GB) - https://amzn.to/4gGAUCp AMD Ryzen 7 7800X3D - https://amzn.to/4pNfeZw AMD Ryzen 7 9800X3D - https://amzn.to/4gM2jmn AMD Ryzen 7 9950X3D - https://amzn.to/42bn1Gd --------------------------------------------------------------------------------------------------------------------------------------------------------------- Title: What's The Best Memory for AMD AM5 Ryzen X3D CPUs? 🔥 Speed vs CL vs Rank vs FCLK 🔥 --------------------------------------------------------------------------------------------------------------------------------------------------------------- Chapters: 00:00 - Introduction 00:20 - Video Focus (Speed vs CL vs Rank vs FCLK) 00:52 - Demystifying AMD AM5 Memory 01:37 - Which Memory Kit Should You Buy? 02:12 - AMD AM5 Ryzen CPU Architecture 03:13 - Optimizing AM5 Ryzen CPU Core Clocks 04:40 - Test Setup & Components 05:26 - Ryzen 9 9950X3D CPU Optimization 06:15 - Test Methodology 06:44 - Benchmark Methodology 07:27 - DDR5-6000 Benchmarks 08:32 - DDR5-6000 Observations 09:18 - DDR5-6400 Benchmarks 10:23 - DDR5-6400 Observations 11:13 - DDR5-8000 Benchmarks 12:18 - DDR5-8000 Observations 13:05 - 6000 vs 6400 vs 8000 Benchmarks 14:56 - 6000 vs 6400 vs 8000 Observations 15:38 - How Do You Select the Best MCLK, UCLK and FCLK Combination? 17:31 - What About Higher Capacity Memory Kits? 19:10 - What's The Best Memory for AMD AM5 Ryzen X3D CPUs? 20:21 - Cost & Value Comparison 21:29 - Final Thoughts 22:08 - Wrap-Up --------------------------------------------------------------------------------------------------------------------------------------------------------------- Blackbird PC Tech Links: Website: https://blackbirdpc.tech/ Store: https://blackbirdpctech.store/ Membership: https://www.youtube.com/channel/UCQwpOG-l1nYHtX2alMFdLFQ/join Twitter: https://x.com/Blackbird_PC Skool: https://www.skool.com/blackbird-pc-tech-4230/about?ref=67e6a7048d9540fe87cbdf1b69bd47f3 --------------------------------------------------------------------------------------------------------------------------------------------------------------- AMD AM5 Test Platform: CPU: AMD Ryzen 9 9950X3D - https://amzn.to/42bn1Gd Motherboard: Asus ROG Crosshair X870E Apex - https://amzn.to/4lG0xot GPU: Asus ROG Astral GeForce RTX 5090 OC Edition - https://amzn.to/3KnEJjE CPU Cooler: Asus ROG RYUO III 360mm AIO - https://amzn.to/3FqnT1B Storage: 4TB Samsung 990 Pro NVMe Gen 4 M.2 SSD - https://amzn.to/4kLsZVe PSU: Asus ROG Thor 1200W Platinum II - https://amzn.to/4mbzwce
