win 7 bsod - okvara matične ?

Računalnik mi je delal brez problemov nekaj mesecev - pri istih nastavitvah, brez navijanja. Sedaj pa mi, največkrat v igrah (orginal) vse skupaj zašteka, pojavi se bsod, vendar samo kadar imam vstavljena dva ram modula 2x2 gb, z enim pa dela. Neglede z katerim ramom od teh dveh in ne glede v katero režo sta vstavljena. Rama sta v redu, preiskusil tudi drugi nov komplet drugega proizvajalca, ista zadeva.Preiskusil z drugim napajalnikom, drugo grafično, disk je v redu, posodobil bios in vse gonilnike. Naložil zadnje gonilnike za grafično. Sistem se ne pregreva. Prosim za pomoč, kajti na servisu niso ugotovili nič.

windows 7 64 bit
AMD Phenom IIx4 955
M4A79XTD EVO - matična
A-DATA DDR3 1600+ (cl 8-8-8-24;1,65-1,85 v)-ram
LC6600 600W - napajalnik
SAPPHIRE HD 4890 -grafična

v dinokompu poglej za plate z 890GX chipsetom. Tale 770 je ze dokaj star.

Če vstavim eno palčko rama - katerokoli od dveh, mi dela v redu, v kolikor pa vstavim dve se mi sesuje. V biosu sem nastavil voltažo na 1.66v, kar je priporočeno, vendar ne pomaga. Poiskusil tudi z drugimi rami (Patriot) isto sranje.

Zakaj ?

procesor ima memory controller ze integreran kaj pa ce je to?

Bolj natančno prosim.

Kako naj pa to ugotovim; niser ravno ekspert. Ampak, meni je zadeva delala nekaj mesecev brez problema.

Jast se še kar matram. Flešal sem bios, ročno nastavi tajminge in voltažo. Če vstavim palčki v različno obarvane reže, mi zadeva dela, seveda v single channel, v kolikor, pa jih vstavim v dual channel, pa mi sistem pri zagonu zamrzne pri windows logu.
