why does my pc3200 ram run at pc2700 speed?
i have the stock samsung pc3200 ram, 256x2, that came in my dell dimension 4600. i opened cpu-z, however, and it reports that the ram is only running at pc-2700 speed, while its maximum is pc-3200. they are matched dual channel ram, and i cant see why they will not run at the higher speed.

If you only have a 533MHz FSB it won't run at full speed. What processor do you have?- Have you added RAM to the system? If so, is it CL-3? If it's faster, the system will downclock.
Or, do you have a 533 MHz FSB CPU? If you do, the memory will run at 333 MHz, not 400. Only if you have an 800 MHz bus P4 will the RAM run at PC3200 speed. FREAKNASTY8297

thats why its running at 333MHz is cause of your processor and bus speed.Message Edited by neobrucelee on 06-12-2005 09:52 AM

and if you upgrade to 800MHz front bus speed you HAVE to upgrade your memory to be compatable with HT technologydrew-and-not-u

Are you sure? I'm pretty sure that such is not the case, but I could be wrong. Where did you hear that? Not trying to lock horns, but I've never heard that before. :smileywink:
