Sprawdzenie ilości pamięci RAM
#1
0
Od pewnego czasu miałem wrażenie jakby system stał się bardziej ociężały niż wcześniej.
Po pewnych sprawdzeniach zaskoczyła mnie ilość pamięci widziana przez system.
Faktycznie na płycie są dwa sloty i w każdej po 1 kości 4Gb DDR3.
System widzi jakby było w granicach 4Gb i tu następna ciekawostka, po każdym uruchomieniu ta ilość jest trochę inna.
W BIOS-ie widać po jednej kości 4096 w każdym slocie. Po uruchomieniu komputera wybrałem "Mtest" i wykonał test bez żadnych błędów (również widział 2 x 4096).
Poniżej co widać po komendzie inxi -Fxz

A w dmesg widać coś ciekawego?
Kod:
dmesg | grep -i mem
Jak masz starszy kernel to można spróbować czy na nim będzie widział całe 8GB RAM.
Można też spróbować z parametrem startowym mem=

Nie grzebałeś w BIOS? Jakieś zmiany napięcia? Timingu? Nie przydzielałeś dodatkowej pamięci dla karty graficznej - zintegrowanej?

Można zainstalować z menadżera oprogramowania Hardinfo (System Profiler and Benchmark) i zobaczyć w Devices > Memory, ile widzi.

Ja bym zaczął od próby przełożenia kości między slotami i/lub prób z tylko jedną kością w slocie.

Od takich eksperymentów oczywiście zacząłem. PC-tami zajmuje się już prawie 30 lat.

Sprawdziłem kości na innym komputerze. Tam ten wykrył w BIOS-ie tylko jedną kość. Wymienię obydwie na inne.
