Hi @chris89, thanks for asking; yeah I had to lower the memory clock to 2085 mhz, because higher values give me some errors in hwinfo and I prefer to be as close as possible to 0.

There is something I would like to ask the community please:

I want to create my custom strap for hynix 8gb, so
I have decoded 777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB030000001B162C31C0313F17 thanks to r_timings

I want to improve this timing strap
is there a guide/tutorial/pdf which explains what all these lines and values mean,what the possible range of values is etc etc..., please?
I've read the PDFs in its topic but I could not find an answer.

Thanks
