(riješeno) Memorija - razlike u SPD i DMI očitanjima
 

Pozdrav,

CPU: i7 920
MOBO: Gigabyte EX58UD4
RAM: Corsair 3x2GB 1333 DDR3 - detalji u nastavku


Nedavno sam uzeo Corsair 3x2GB kit DDD3 1333, nakon instalacije i boot-a POST screen je izbacio svih 6GB OK, BIOS također vidi svih 6GB ali prilikom provjere memorije pomoću CPU-Z i SiS Sandre na DMI read levelu nedostaje jedan stick.

CPU-Z export (timing odrezan zbog dužine post-a):

Kao što se može vidjeti, na SPD levelu je se OK ali na DMI fali jedan stick.

Isto očitava i SiS Sandra:

Na memory controler tab-u fali jedan stick.

Napomenio bih da Windows task manager vidi i koristi svih 6GB kao i main screen u CPU-Z koji ne pokazuje nikakve devijacije:

Zaključno, devijacije se vide u detail exportu i CPU-Z i SiS Sandri na DMI očitanjima, sve drugo ne odstupa od normalnog.

Bio bih zahvalan kada bi netko prokomentirao rezultate i dao mišljenje o uzroku devijacija (možda neispravan memory controller na procesoru ali ne bih htio ništa sugerirati).
Naravno, da nisam imao viška vremena i radio exporte i kopao ne bih ništa primjetio obzirom da task manager i CPU-Z ne očitavaju nepravilnosti u standardnom view-u i kanta radi stabilno , proklete moderne teNhnologije.

Btw, ovo bi mogao biti problem dokazati u procesu garancije. :stoopid:

Hvala unaprijed

Problem riješen. :goood:

Flash BIOS-a.

Eto quick fix za korisnike Gigabyte EX58 serije ploča ako se nađu u sličnoj situaciji.
