lakroquette Posted March 7, 2005 Share Posted March 7, 2005 i own an Asus P4P800SE motherboard, i installed 2 memory modul (256mb PC4000 XMS). In the bios, memory modul are properly detected, but when i open windows XP, memory work only at 200MHz (instead of 400MHz) The PC4000 memory modul is made to work at 500MHz but the P4P800SE motherboard is limited to 400MHz i will try to update my bios version help please... :(: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 7, 2005 Corsair Employees Share Posted March 7, 2005 DDR memory would be 200 MHz X 2 = DDR400. So what application are you using to see the frequency? Chances are that is correct. You can also use http://www.memtest.org to see that it's running at DDR400 as well. Link to comment Share on other sites More sharing options...
lakroquette Posted March 28, 2005 Author Share Posted March 28, 2005 the application I use is CPU -Z what is strange is that memory modul are shown to run at 400MHz in the Bios but it display 200MHz for each memory modul under Windows ( with the CPU -Z application )...

leeghoofd Posted March 28, 2005 Share Posted March 28, 2005 Well don't worry about that it's the real speed of the memory, that's why they call it double data ram 200x2 = 400DDR Just bench them with eg Sisoft sandra or Everest home and you will see that the memory is working at it's correct speed. These rams give you some more headroom when overclocking. Don't worry about CPU-Z reading your system is fine :laughing: Link to comment Share on other sites More sharing options...
Wired Posted March 29, 2005 Share Posted March 29, 2005 You'll need to manually set the memory to 250 Mhz to reach its full speed, but the motherboard and/or CPU may not be able to OC that high. Link to comment Share on other sites More sharing options...
