    • DDR5-5600 64GB SO-DIMM RAM Benchmark Results (ODROID H4 Ultra)
Size: 64GB Style: 5600MHz
Works great without issue, but it's only been a few days. Couldn't find another brand or 64GB SO-DIMM RAM and I'm glad I won't need to seek any alternative as I'm having no issues with this. I'm using it for an ODROID-H4 Ultra which only supports a single channel, despite this the performance of it is great. Test System: Board: ODROID H4 Ultra CPU: Intel Core i3-N305 (8-core, Alder Lake-N) RAM: 64GB DDR5-5600 SO-DIMM (single stick, single channel) OS: Ubuntu Linux Benchmark Tool: sysbench 1.0.20 🔧 1. Single-Threaded Write Test (1 KiB blocks) - Bandwidth: 6.27 GB/sec (6274 MB/sec) - Total Data Written: 100 GiB - Threads: 1 - Block Size: 1 KiB 2. Multi-Threaded Write Test (4 threads, 1 KiB blocks) - Bandwidth: 7.31 GB/sec (7313 MB/sec) - Threads: 4 - Block Size: 1 KiB - Total Time: 10 seconds - Total Data Written: ~73.1 GiB 3. High-Efficiency Write Test (4 threads, 1 MiB blocks) - Bandwidth: 31.6 GB/sec (31633 MB/sec) - Threads: 4 - Block Size: 1 MiB - Total Data Written: 20 GiB - Total Time: ~0.65 seconds 4. High-Efficiency Read Test (4 threads, 1 MiB blocks) - Bandwidth: 89.8 GB/sec (89836 MB/sec) - Threads: 4 - Block Size: 1 MiB - Total Data Read: 20 GiB - Total Time: ~0.23 seconds Summary Despite being limited to single-channel operation due to the ODROID H4 Ultra's single SO-DIMM slot, this 64GB DDR5-5600 module delivers excellent real-world performance. Large-block sequential read/write tests show bandwidth well beyond expectations for an embedded system, while even small-block performance is solid. The RAM operates efficiently across various workloads and shows no sign of throttling or instability. ... show more

    • Very happy with value of my purchase. Bought at the perfect time
Size: 48GB Style: 5600MHz
I am so happy I bought this ram before the price skyrocketed. Works perfectly fine on my Asus vivobook 15 OLED. It only has 1 ram slot and this was the biggest I could put in. So I'm happy. I was able to sell the 16gb that came installed for more money than I paid for this. Lol. Free upgrade
