Tested 13 cycles of TestMem5 Absolut + 3x OCCT 1 hour memory stress test
Hynix CJR/DJR kit (2 – 3 years old but I still have no idea which)
ProcODT can go down to 40 ohms, but not sure what this does? I read somewhere it allows for 'cleaner signals' but when I set ProcODT lower the Read/Copy variation between runs in AIDA64 increases.
VDIMM will go down to 1.44V, but I guess the 0.01V doesn't really do much so I've left it at 1.45V.
tRFC *can* go all the way down to 427 cycles (228ns) but will corrupt files very quickly. 434 – 435 cycles has passed 6 – 7 hours of TestMem5 and OCCT GPU + RAM, so I think it's mostly stable?
tRC at 57 cycles is the lowest this kit will do, also saw multiple kits stuck at tRC 57 online, although one user had tCL at 14 (how?) tRAS is ignored when tRC is set this high, tRCDRD and tRP could not do 18 cycles.
Are any of the timings potentially rounded due to GDM? i.e. tRC at 57, tWTRL at 7, tWRRD at 1? Could loosening timings potentially increase performance and decrease latency? In before, my 5600X did 54ns at 3800MHz, now this 5800X3D does 62ns?
