Problem when overclocking 800 to 1066 P4T533-C Tags: CPUs Overclocking Memory Last response: November 6, 2002 12:06 AM in CPUs Share peterjedi November 3, 2002 10:52:43 PM I am having trouble overclocking my Asus P4T533-C, 2.53 P4 with 4 PC800 256MB 184-pin Samsung memory, 800-40, MR16R1628DF0-CM8. Evertime I change my RDRAM/FSB frequency from Auto to 4 my computer will only reconize 391 MB (should be 1GB). Sometimes my computer freezes. If I change my memory back to Auto, all is fine. I think I am using the latest BIOS, Rev 1008. Am I doing something wrong? Do I need to change the jumpers? My advance BIOS settings are: CPU Speed -> 2.53 (Using Dacris, CPU tested at 2.25) CPU Frequency multiplier -> 19 X CPU/PCI Frequency -> 133/33 RDRAM/FSB Frequency -> Auto (Had problems with 4) When I tested my memory using Dacris software it said my memory was too fast for my CPU. Should I change the mutiplier? Any help would be much appreciated.

Therefore you should go to BIOS, Advance menu change RDRAM/FSB Frequency Ratio back to 3X. Your memory modules are not so good to work under PC1066 mode.
