DDR5-5600 64GB SO-DIMM RAM Benchmark Results (ODROID H4 Ultra)
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.

Used to upgrade UGREEN NAS - no compatibility issues
Installed without any issues in my Ugreen DXP2800 NAS. Allowed me to upgrade from 8gb. Matched the speed that was supported at 4800mhz and has been running stable for about 4 months now.

Perfect for UGREEN NAS
Got it to replace/upgrade my Ugreen NAS stock ram. Easy to replace it - just watch a video on youtube or follow instructions carefully provided with the NAS. Great quality memory stick. Works flawlessly and it's super fast.

Very happy with value of my purchase. Bought at the perfect time
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

Made a noticeable difference in laptop speed
I ended up buying this Crucial 8GB DDR5 SODIMM (5600MHz, CT8G56C46S5) even though it cost more than I really wanted to spend — but honestly, it was worth it. After installing it, I noticed a real improvement in overall laptop speed, especially with general responsiveness and multitasking. It just feels snappier. Install was straightforward (standard laptop SODIMM upgrade), and it’s a known brand so I felt good about reliability. This module is DDR5 SODIMM, 262-pin, 1.1V, so make sure your laptop actually supports DDR5 before ordering. Bottom line: Had it been a bit more affordable, I would have given it 5 stars. Not the cheapest upgrade, but if you’re running low on memory and your laptop feels sluggish, this one can make a significant difference.

Beklentimi karşıladı
Asus A15-FA506NF Ryzen 5 7535hs işlemcili 8gb DDR5 ram'i olan laptopa 2.slot için aldım taktım gayet güzel çalışıyor,her ne kadar üstündeki samsung olan ram 4800mhz ile kısıtlansada buda tabi aynı frekans ile çalışıyor.her ikisinide 5600mhz de çalışması için bios ayarlarındaki menüden ayarlamak kalıyor ama gerek yok 4800 ile 5600 mhz farkını hissedemeyiz zaten,satıcı ve platforma tşk.
