Overclocking
Disclaimer: Overclocking is never guaranteed, so the results may vary depending on certain conditions and various hardware configurations. I am not recommending overclocking if you do not know what you are doing. High voltages may damage hardware, and the warranty will not cover it.
Considering that two 48GB modules are in use, they overclock pretty well. Few laptops or desktop motherboards with SODIMM DDR5 slots will support RAM overclocking or additional options. If we are lucky, we can improve the performance a bit, but I wouldn’t count on anything spectacular.
Our motherboard won’t let us adjust all timings and won’t support higher voltages on a regular RAM series. Crucial uses very popular Richtek PMIC, but voltages are still locked on our test motherboard.
The memory kit could reach DDR5-6200 CL42-41-41 at 1.10V VDD/VDDQ. It’s a respectable result and already a significant improvement over the SPD profile.
The used IC is similar to what we could test in desktop, full-size DIMM modules from Crucial. Assuming a similar scaling, we can count on up to DDR5-6400 and CL36-38 at a 1.35V. What surprised us was the significantly lower tRCD and tRP on the SODIMM memory, as we could lower it to 41, while on the desktop modules, we couldn’t set it below 44/45.
If we set tREFI at 65k, we can count on about 8GB/s higher bandwidth and 10-12ns lower latency. However, on our test PC, the memory kit wasn’t stable at anything above auto tREFI (so each training was around 5k).
No brand offers faster 96GB DDR5 SODIMM memory, so it’s the way to go if we need high-capacity RAM for a mobile or SFF PC. If we have a computer that additionally lets us overclock the RAM, it’s already a win-win situation as we can improve the already respectable performance.
