IVIYTH0S Posted January 24, 2011 Posted January 24, 2011 have you prime 95'd it a couple hours at 3.4ghz?? what's your memory speed?? Share this post Link to post Share on other sites More sharing options...

dario_92 Posted January 24, 2011 Posted January 24, 2011 I am running prime 95 just now i do this till 2:30am/3:00am (uk time) Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted January 24, 2011 Posted January 24, 2011 I think your memory speed is what is causing the instability at 3.5ghz as it's over 1600mhz and they may not like going too far above their factory rated (it's at 1768mhz at 3.4ghz) 3.5ghz would have the ram running at 1842mhz which would most likely cause the it's instability Share this post Link to post Share on other sites More sharing options...
dario_92 Posted January 24, 2011 Posted January 24, 2011 would raising the multiplier to 20 and then the blck to 175 = 3.5GHz. Im sort of new to this overclocking so i need as much help as i can Share this post Link to post Share on other sites More sharing options...

IVIYTH0S Posted January 24, 2011 Posted January 24, 2011 is there anyway i can change this ? should be. Can you get some screenshots of you bios, there should be a way to lower your ram speed. Though if you lower the bclock and raise the multiplier that will lower your memory speed in a different way than I was suggesting. Why aren't you at the 21x??

dario_92 Posted January 24, 2011 Posted January 24, 2011 profile memory is in X.M.P Share this post Link to post Share on other sites More sharing options...
dario_92 Posted January 24, 2011 Posted January 24, 2011 Ok, so i managed to get 3.48GHz with my RAM at 1660MHz Is my ram speed ok as it is 1600MHz ram i have ? Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted January 24, 2011 Posted January 24, 2011 yeah I mean if it runs stable over it's rated speed awesome, i just think that the memory divider before made them run too high a speed and that's why you'd crash. Now you may keep going to your known ram limit Also STRESS TEST! Share this post Link to post Share on other sites More sharing options...
dario_92 Posted January 24, 2011 Posted January 24, 2011 yeah i got it to 4.0ghz last night but it wasn't stable to i just put it back to 3.20ghz with 1600mhz ram. i love this chip lol Share this post Link to post Share on other sites More sharing options...
