The 40% improvement in 5%low in baldur3 using Die2Die and Ring improvement is crazy!
still far from the 9800X3D but still impressive.

You know when ddr3 first came out they're 1.65v and can be daily use for 1.8-1.95v with fan over them.

Can you post the before and after screen shots for the memory tweaking between XMP "defaults" and the XMP plus tweaks? It's a large latency improvement before the bus updates. Also what is the settings that the ring and d2d updated to?

@ir_cow I guess on page 1 capacity should show 2x24gb, not 2x16? Just nitpicking, thanks anyway.

You just want a screenshot of the default timings?

It's a large latency improvement before the bus updates. Also what is the settings that the ring and d2d updated to?
For this one it was 42X ring and 32X D2D. NGU had no improvements at all. I also observed that if you go higher in memory frequency the lower the overall multiplier for Ring and D2D is. For example at 9600 MT/s, I couldn't get passed 30x on the D2D without some unhealthy amount of voltage applied. Idk if this is normal, or just the motherboard i'm using.

Also this memory could run 9600 MT/s, but it wasn't really worth a mention in the overclocking section.

Yes please!

Did you have to increase voltages for ring and D2D? I know it's mileage varies but overclocking has gotten complicated.

I did not. The Ring already had 1.3v applied from the SA rail (by default) and the D2D worked at 0.75v. 34X D2D needed 0.90V so I just left it alone to show that you can still get good results without voiding warranties.

It feels overly complicated at first, but it is really just new names and what voltages to go what is the learning curve.
