Memtest & error

[Harris Kosmidhs]

Τελευταία παρατήρησα διάφορα crashαρίσματα στο Ubuntu μου. Πετούσε και 
στο gnome-terminal και στο kern.log κάτι του στύλ:

Με τα πολλά έτρεξα ένα memtest. (v.1.68)

Το αποτέλεσμα μετά απο 7 ώρες ήταν το παρακάτω:

WallTime	Cached	RsvdMem	MemMap		Cache
--------------------------------------------------
7:06:36		1024M	88K	e820_std	on

στην ίδια γραμμή
Ecc	Test	Pass	Error	ECC error
---------------------------------------------------
off	std	13	5	0


απο κάτω:

Test	Pass	Failing Address		Good	 
----------------------------------------------------
3	4	000008c1c8-0.7MB	0808808

Bad		Err_bits	Count	
----------------------------------------------------
08084808	00004000	5


μπορεί κάποιος να μου αποκρυπτογραφήσει το μύνημα;; :-)

Ευχαριστώ
