Valami zabálja a memóriát.
Sziasztok, a gépemen fut már jó pár éve a "ZoneAlarm Security Suite" tűzfal, antivirus és antispyware program. Kb egy hónapja figyeltem fel arra, hogy megnőtt a memoria felhasználása. Míg eddig cca 200-450M között mozgott a memória szükség, most 900-1600M körül mozog. Ha kikapcsolom a ZA programot, leesik a foglalt memória 350-40M-ra. Kérdezném a ZA programot használókat, mi a tapasztalatuk? Illetve bárkit, aki magyarázatott, megoldást tudna adni. János.
UTP csatlakozó

Üdv!

 

Jutányosan hozzájutottam CAT6 F/ UTP földkábelhez, (4x2x23 AWG PE) amit be is húztam a helyére, de az UTP csatlakozót az istenért sem tudtam rátenni, nem tudom kellően beledugni a csatlakozóba.

Próbáltam CAT5-ös és CAT6-os csatival is elméletileg. Már ha a boltba jót adtak.

Milyen csatit tudok erre rárakni?
