Need Help On Overclockin My P4

rollier0401 · 21-April-03, 11:51 PM

Ok, heres the deal, i've got my p4 oc'ed from 2.2 to 2.54 right now, my fsb is at 154. I know I should be able to go higher, but i cant lock my pci/agp. I've heard of 100,133,166 fsb speeds being magic numbers in that they keep the pci/agp at 33/66. Does anyone have any suggestions other than getting a new m/b or proc. My vcore is set at 1.6, and my temps are good at 38C load. When i go from 154 fsb to 155 i'll run 3d mark03 and 01 and a little ways into it the screen will freeze. Any suggestions will be appreciated. Also what do you think about jumping from 154 to 166 fsb, in hopes of reaching that magic number. I just hope i'm not at the limit of my proc, i dont think i am.

The lock that you talk about is a BIOS setting which will force the AGP/PCI buses to be at 66/33 mhz. If your bios doesn't have a little option for that, just moving to 166 won't actually enable the setting. And since I'm assuming stock was 100 mhz, that sounds fine to me with (assume) stock cooling

The stock fsb on my board was 133, when i talk of the pci/agp being at 33/66 i had just heard that if you cant lock them, keeping your fsb at 100,133,166 will keep the pci/agp at 33/66
