So to start my system specs are as follows:
9800x3d
g skill ripjaws m5 neo 6000 cl28 2x16gb
gigabyte aorus b850 elite
9070xt
seasonic 1000w
I've been on bios version F7 for awhile running Buildzoid easy Hynix timings cause I didn't want to go down the rabbit hole like I did with ddr4. Time is something I don't have anymore. Everything was running smoothly. Did all the test Tm5 with all configs including x3d, vt3, Adia64 cpu fpu cache, hci memtest, prime 95 etc. Also have a per core undervolt which have vetted too. So I updated the bios yesterday to F11. Started trying to teak the memory further just to mess around. I can't for the life of me to get anywhere. Even my solid previous settings are failing in vt3 after like the 4th or 5th iterations. I've tried gdm off, nitro mode 1/2/1, 1/3/1 and nothing. I've messed with some voltages and even went back to 1.4v on the dimms. Before on F7 the refresh was normal in stead of mixed. I've tried going back and switching it back to normal but that yeilds the same results. I haven't even tried with upping the mclk/uclk nor the fclk. I've turned of integrated graphics and bankswap group is swap apu. With nitro mode at 1/2/1 and trefi maxed out I had 17,000% coverage on Karhu with no errors and tm5 no erros, but vt3 10 mins in and everytime it's coefficient to large. I'm at a lost. No I do not know what every timing does or means, but I have and idea and I'm good and narrowing stuff down. In my testing I disabled pbo and still same results. So the cpu as far a I know is not the issue. My goal is pretty modest. I just want 6200 1:1 with faster than 2000 fclk and gdm off lol. It has posted every time even with gdm off and nitro mode 1/2/1 at 1.4v on the dimms and soc 1.25v. The memory aslo runs around 45c or below.
