Nevets Posted December 24, 2006 Share Posted December 24, 2006 I am a bit inexperienced in OC'ing (OK I'm just a newbie in dual core OC'ing who has OC'ed a single core CPU) and I am trying to OC the FSB on the EPoX MF570SLI AM2 board. I am using the latest BIOS and the only significant changes that I made on the memory page was to change the 5-5-5-18 timings to 5-5-5-12 as the stick should have been read. I enabled the PCIex Spread Spectrum, CPU Spread to center. I have the memory set at 800 instead of auto, interleaved, and I have set the VDimm to 1.9 instead of auto. I also have the CPU Clock set to 11, and I have stock FSB (In this BIOS it is called 'CPU Overclocking') which I beleive to be the FSB. When I increase the CPU Overclocking to 10 (it ranges from 1 to 250) and reboot the POST indicates that I am running at 2310 (210X11) with DDR2 800@385Mhz. However when windows starts and I check with CPU-Z, it shows the board in the default clock mode of 2211.8; 11 X 201.1. The memory change that I made to the BIOS memory page going from 18T to 12T sshows up in CPU-Z. The same results are given when I am at 11 +25 which the POST reads as 2475 (225X11) DDR2 800@412Mhz which is what I expected. But CPU-Z and CBID both indicated that I am still at 11 and 201.1. At 2970 (270X11) POST with DDR2 800 @495Mhz 5 5 5 12 2T. No change in CPU-Z. I played this game last night and went all the way up to 3025 (275X11) POST but no change in CPU-Z. Now this board has a nice Thunder Heat Probe that I placed on the side of the CPU Heatsink and there has been no increase in the temperature of the CPU. This is confirmed by Ghost Monitor that shows the CPU at 38C throughout the experience. This leads me to believe that either the POST is wrong and the CPU-Z is right and that I have not done anything at all to the FSB or I actually clocked the CPU at 275X11 for 3025. The only other obvious thing is that I am off in never-never land and I really don't have a clue. :D: Also, if this memory is PC6400 800 why is the POST defaulting to 386Mhz instead of 400Mhz (DDR 200X2=400 X 2 = 800 for PC6400 800)? How do I resolve this so that I can get to OC'ing. TIA Link to comment Share on other sites More sharing options...
