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.

It sounds that your PC800 memory cannot work at 4*133MHz. 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.
There's a reason PC1066 cost more than PC800, let's see if I can remember what it was...nope, sorry.
