My current set up consist of a P4 506 CPU (stock H/S and fan)- MSI 915P NEO-F and a Sapphire X1600Pro 128mb PCI-e all of this is contained in my powermax case with 3 fans. As of now I can only get this processor up to 3.0Ghz @ 148 fsb. I try to push it higher but the system will not POST and I have to reset the BIOS. I've heard that this processor can overclock higher, but I am having difficulty. Also I find that this mobo doesn't have the overclocking features I've had on my previous mobo (MSI 645 MAX-E). Does anyone in this forum own a 915P mobo? I am looking for the memory divider and voltage control for the CPU, I can't seen to find under the BIOS "cell menu". Please help if you can or give me any other info that may help me overclock the configuration I have to higher speeds.
