oc'n question -> uncore/nb

post #1 of 8
Thread Starter 
hey guys im new to the stuff and recently read lots of articles due to oc'n i7s and from what i got i always have to push nb/uncore speed to double of dram speed.
this has something to do with up and down speed for my ram controller right?
could someone pls explain to me?^^

so if my uncore would run below double ram speed it will just kind of bottleneck the ram right? and not do any damage?

Hi,

This rule about double of ram is only for s1366 ( bloomfields )

Lynnfield's i7 have always x18 for uncore and i5 ( 750/760 ) have x16 so only way to increase this is raising blck.

Don't cause bottleneck if cause is a little, don't affect gameplay.

I do many benchs in games with low and high uncore, 133x30 ( uncore 2400) , 200x20 ( uncore 3600mhz) , 160x25 ( uncore 2890mhz ) and i can't see much difference.

sorry for my bad english

thanks for the information on s1366 and lynnfield
hmm ok mb no bottleneck but it still doesnt make sense to use ram on 2000mhz if uncore is only 3000mhz right?^^
so its time for some more bclk oc

With your i7 870 you can ignore the uncore speed. Just focus on getting your bclk as high as possible, tweaking vcore and vtt along the way. If you can run your ram at 2000 mhz stable, that's great, it doesn't matter what your uncore is. The system will be fine.

hmm ok but from what you guys say it is only a 1366 thing to keep uncore= 2x ram speed? how comes?
