ok, than i will install unigine-heaven (AUR) now. ohh failure hmmm than i try glmark, important is: #benchmark
-> phoronix-test-suite
phoronix-test-suite install unigine-heaven
phoronix-test-suite run unigine-heaven
I combinate it with psensors in a seperated window, so i can check the temperature, too. (CPU ~56°C)
have someone a additional hint about uefi-firmware, too?
yesterday i wanted to RAM OC 3200->3466 MHz. Problem, Grub (hmm or UEFI-grub) is not available on booting.so i can not select start uefi. later than i broken grub and have to repair via chroot -.-
that what i am now thinking, the problem is HDMI-0 , Display-Port or the combination of Display-Port and Display-Port->HDMI-Adapter. I do not know. That what i am mean is.
If I boot: Arch Linux kernel drivers and Login, but before just black screen. Grub is set timeout=5 and in uefi is csm off and full logo off.... that i do not see: press del, press esc, press f11 ...
[now i have replugged again cables \o/ I see press f11.... (atm over display-port, before hdmi-0) i think, it is not normal and a failure of a confused x300-firmware[1.79]. <-- that "trouble" i have just because if i want to visiting UEFI-settings, so that normal times, it is unimportant. Im just ***up we all know that A$r0ck can not build good firmware!
