eon_designs Posted January 6, 2008 Posted January 6, 2008 This may have been asked before - apologies if it has: Most of the overclocking guides say that you should have your ram running in sync with your FSB at a 1:1 ratio (at least to start with) I am using Corsair PC2-8500 ram (speed 1066Mhz) Currently I have my ram running at 890Mhz with my FSB at 356 so my ram ration is 4:5 - the question is - is it better to have the ram running at a lower speed but at a 1:1 ratio with the FSB or as I have done put it as high as it can be without overclocking it? Many thanks. Share this post Link to post Share on other sites More sharing options...
kingdingeling Posted January 6, 2008 Posted January 6, 2008 If you are not going to be adjusting the timings (essentially overclocking), then you should run it as high as is stable. If you're going to be adjusting the timings, running medium FSBs at better timings might be the better choice for performance Share this post Link to post Share on other sites More sharing options...
Comp Dude2 Posted January 6, 2008 Posted January 6, 2008 lol, i am a little confused with the 4:5 thing, maybe i dont understand ram dividers properly but on my board you just set it as a multiplier (i guess you could call it 1:2 instead of 2x etc) but you appear to have you ram at 2.5x (356x2.5=890) so i would bump it up to 3x because that gives you 1068Mhz which is pretty much stock speeds. And i'll assume this is a Core2 rig so speeds are more important than timings Share this post Link to post Share on other sites More sharing options...
kingdingeling Posted January 6, 2008 Posted January 6, 2008 Comp_Dude, the way RAM dividers are set up is different for every board, for example on my Blood Iron, it goes from 266/800 to 333/1600 or something weird like that. First being the chipset strap, then the frequency, but I might not have fully understood that yet Share this post Link to post Share on other sites More sharing options...
Comp Dude2 Posted January 6, 2008 Posted January 6, 2008 lol, thats a bit of a jump. But yeah, i know what you mean, my point is though his is set at 2.5x, whatever way it is done in the bios, and raising it to 3x would be the way to go Share this post Link to post Share on other sites More sharing options...
kingdingeling Posted January 6, 2008 Posted January 6, 2008 There's settings in between man! I was just giving an example Share this post Link to post Share on other sites More sharing options...
Comp Dude2 Posted January 6, 2008 Posted January 6, 2008 (edited) oh lol, those are the max and min speeds! i thought that was one step to the next and though "that wouldnt be much use" lol that would take you from Edited January 6, 2008 by Comp Dude2 Share this post Link to post Share on other sites More sharing options...
kingdingeling Posted January 6, 2008 Posted January 6, 2008 The lowest is even lower when I think about it... something like 266/533 or so, but don't take that for sure... Share this post Link to post Share on other sites More sharing options...
Comp Dude2 Posted January 6, 2008 Posted January 6, 2008 yea, the lowest on mine is 2x so at stock speeds it would be 400mhz (i dont think ddr2 goes that low lol) but 667 at my current speeds. which i guess is fine unless you wanted an fsb greater than 400mhz lol.
