So from my tuned 6400 gdm on to tuned gdm off I had to loosen:

Tras +1 - 31 tras is weird could've set to 126 but eh I like low numbers and 31 works. 30 causes issues.

Trrdl +2

Twtrl +1

Trfc2 +1 -might loosen more but seems good for now

Trfcsb +3 -might loosen more but seems good for now

Rdscl +1

Trtp +1

Trdrdsd+1

I have also minimised voltages so 1.3 soc is unfortunately needed here but my fclk 2133 doesn't care at all so it's fine.

I've tried for CL26 with gdm off using high voltages but my memory was not happy at all.

Also I've found that tuning with gdm off @6400 64GB greatly increases the risk of corrupted files lol I was able to fix them all as I regularly scanned throughout the tuning process. One time I logged into windows the screen flashed grey with lines everywhere😆

56.8ns not too shabby for 64GB standards was hoping for sub 56ns but that's just not possible for my setup. Latency killer was not used as my budget motherboard doesn't support such features.

I am using a 7800x3d same stock frequencies as seen in y-cruncher. fgr and mixed are basically tied for latency in PYPrime 2.0 with normal being slowest on average. However, the most noteworthy thing I'm showing here is the huge bandwidth gain from mixed mode in y-cruncher pi 1B being 2.6 seconds faster than fgr and normal with a properly tuned 16gb m die that benefits most from mixed mode out of all dies because it can run super low trfc2 288 trfcsb 178😆. The refresh modes im using are shown in Zentimings.

My Kit is 16gb m-die 64GB. I ran 5 tests for each mode on both benchmarks and just grabbed the best results. For cs2 dust2 I ran 1440p low preset on both modes with an overclocked 5080 +345mhz on core +6000 on mem (yes it's stable) using GCC instead of MSI ab as MSI is capped at +3000 wink wink. For OCCT it gives around 10ns worse latency results than aida64 which I don't like as it shows just how inaccurate any software can be with memory latency. Mixed mode gives 2ns better latency on average than normal with my kit for both Aida and OCCT. Mixed is faster for m-die as you cannot go below 150ns normal. If you could do 90ns trfc1 normal it would outperform 90ns mixed but not possible for m die.

For the Testmem5 config I raised voltages to be 100% that if I error it would be a timing issue and not a voltage issue. I will minimise voltages but for now not a problem I have good cooling. Please let me know what other stress tests to use if you are not convinced.
