Immortal 0 Posted September 22, 2002 Hi all, I was wondering, can i use PC133 SD-RAM when my motherboard has a 400Mhz FSB (QDR 4x100) with my P4 mounted on a Jetway P4XFA? If i set my FSB @ 100, but set my DRAM clock to 133 what will happen? This is becuase i dont know what RAM to get; PC100 or PC133. One more question, my mobo supports PC2100/2700 DDR RAM, is there any real world gain by using DDR RAM over SD-RAM? Thnx! Share this post Link to post
sapiens74 0 Posted September 22, 2002 A lot to be gained if you use DDR instead of SDRAM. As to your other questions. THe PC133 setting is for the memory alone and not for the FSB. So at 100 or 133 the FSB will remain 400 Share this post Link to post
Immortal 0 Posted September 22, 2002 Thnx a lot mate, that helped a lot. What kind of differnce can i expect from using DDR tho? Share this post Link to post
sapiens74 0 Posted September 27, 2002 Pentium 4's are much more reliant on the memory bandwith then are the Athlons So you will see some big improvements Share this post Link to post
