your findings were true eva . today I tested this kit, and managed to get 925 6-6-6-20 32m stable at 1.8v bios set vdimm / around 1.792v real /
1000 6-9-6-20 1.84v win boot ok, but 32m stability is far even with 1.88v bios set vdimm ish..
seems, not trcd is the limiting factor
i think i"ll go cold with them
