cswit Posted June 26, 2008 Posted June 26, 2008 i have a foxconn 946gz7ma motherboard that is supposed to go up to 667mhz i have 2 gigs of ram one 1gig of pc2-4200 and i gig of pc2-5300 each one is only running at half the speed that they are supposed to i hae no clue why and wat does 1:2 fsb:dram mean Share this post Link to post Share on other sites More sharing options...
hardnrg Posted June 26, 2008 Posted June 26, 2008 PC4200 = 262.5MHz = DDR525 mixing RAM sets both sticks to the same speed, the lowest of the two, or sometimes even lower than that... 1:2 is the ratio of speeds comparing the FSB to the RAM... so the RAM should be at twice the speed of the FSB next time, make a more descriptive topic than "RAM", imagine if everyone did that for all topics...

cswit Posted June 27, 2008 Posted June 27, 2008 (edited) the box says pc2-4200 is 533 and 5300 is 667 they are running at 266 and 333 respectivly i am very confused Edited June 27, 2008 by cswit Share this post Link to post Share on other sites More sharing options...
hardnrg Posted June 27, 2008 Posted June 27, 2008 google, download, run: CPU-Z CPU-Z > Memory that tells you the speed... they are not running at different speeds Share this post Link to post Share on other sites More sharing options...
Comp Dude2 Posted June 27, 2008 Posted June 27, 2008 DDR double data rate, they are running at 266, but effectively at 533. And as hardnrg says, they will both be running at the same speed (266Mhz me thinks) Share this post Link to post Share on other sites More sharing options...
cswit Posted June 28, 2008 Posted June 28, 2008 cpuz was the one that told me they were running at the speeds said before Share this post Link to post Share on other sites More sharing options...
cswit Posted June 28, 2008 Posted June 28, 2008 could the fact that my mobo is dual channel be the problem Share this post Link to post Share on other sites More sharing options...
hardnrg Posted June 29, 2008 Posted June 29, 2008 cpuz was the one that told me they were running at the speeds said before you are reading the SPD tab and not the Memory tab... the Memory tab has the Timings information including the DRAM Frequency... THIS is your current RAM speed Share this post Link to post Share on other sites More sharing options...

hardnrg Posted June 30, 2008 Posted June 30, 2008 the SPD tab tells you information that is inside the RAM... this SPD information sets the timings according to the speed... the standard speeds for your RAM are 266 and 333, but they are not running at those speeds, that is just the speed *rating*... you can run the RAM at a different speed, and you can see on the Memory tab that your RAM (all of it) is running at 322 MHz with the following timings so one stick is overclocked 266->322 and one is underclocked 333->322 Share this post Link to post Share on other sites More sharing options...
cswit Posted June 30, 2008 Posted June 30, 2008 (edited) now that we got that cleared up why does my box say different? it says 533 and 667 and my mobo paper says fsb 1066 oc but right now its only at like 644 or something like that how can it go up that high and why when i take it up to about 700 does windows dump memory Edited June 30, 2008 by cswit Share this post Link to post Share on other sites More sharing options...
hardnrg Posted June 30, 2008 Posted June 30, 2008 1) read post #5 in this thread 2) overclocking Share this post Link to post Share on other sites More sharing options...
