I recently built a system for my daughter for her birthday using the following primary components:
- AMD RYZEN 5 1500X 4-Core 3.5 GHz (3.7 GHz Turbo) Socket AM4 65W YD150XBBAEBOX Desktop Processor
- ASRock AB350M-HDV AM4 AMD Promontory B350 SATA 6Gb/s USB 3.0 HDMI Micro ATX AMD Motherboard
- Samsung 850 Evo 256GB SSD
- SAPPHIRE Radeon RX 460 DirectX 12 100409-2GOC-2L 2GB 128-Bit GDDR5 PCI Express 3.0 CrossFireX Support Video Cards
- EVGA 430 W1 100-W1-0430-KR 80+ WHITE 430W Power Supply
- CORSAIR Vengeance LPX 8GB 288-Pin DDR4 SDRAM DDR4 2666 (PC4 21300) Desktop Memory Model CMK8GX4M1A2666C16
I ran Passmark's PerformanceTest 9 and all tests came back with relatively good results with the exception of my memory. All numbers were extremely low (in the bottom 2% in latency and bottom 20% in all other categories compared against the same memory model in PerformanceTest). I know this system isn't a super high performance machine, but I feel like I should see much better numbers versus my exact same memory module that are probably in much older systems, or that at least the latency number indicates a serious issue. What could cause this?
I installed the AMD All-In-One drivers that came with the MB, as well as the newest Radeon software and all the drivers it recommended. The MB reports the ram as running at the rated speed (2666). Is there a potential BIOS setting or driver install I missed, or does this just indicate a bad stick of RAM?
