Interesting, I OC my DDR 5 5600 CL36 (samsung die) to 6000MT/s (kept the same timings, otherwise it won't boot) via MSI try it and use their MSI Hyper Efficiency Mode. Curious how a 5600 CL36 set perform compared to 6000 CL30.
MSI try it is pretty good, isn't it? Makes it easy to see how far your RAM goes. Once you found the fastest one that is stable, you can use that as a baseline to OC further.
Yeah, I just enabled it and chose for 6000MT/s 36-36-36-36. I tried lower timings (saved BIOS before), but PC wouldn't boot. Fix it by taking CMOS battery out for a few seconds and loaded the previous BIOS settings.
About 7% additional maximum memory bandwidth - so if you were in a 100% memory bandwidth constrained situation that would be the maximum performance uplift. But being 100% memory bandwidth constrained is extremely rare so it's probably a marginal improvement. But hey, any extra performance for free is a good thing.
