I have a slight dilema. I had a Gigabyte board that had a SiS748 chipset with a XP 2500+ and 512 mb of PC3200. I was able to run stable 11 x 200 with no problems. I was not able to go higher due to PCI/AGP lock. Plus mobo had no multiplier option. So after hearing about how great Nforce was, I purchased the mobo in my current profile. Well, nothing but bad luck. The best I can currently do is 10.5 x 200. I have 2 x 512mb PC3200 running dual channel. My FSB/RAM divider is set to 1:1. My RAM is running 2.5-3-3-6 w/ 2.7 vdimm (no options in BIOS to go higher). I have tried to go higher with looser timings and vcore at 1.75 but still no go. I cant' even get this board to run 11 x 200 stable. I do have a piece of crap power supply and wonder if that is the problem. Actually not the one in my profile....350w at the moment. What settings do you all recommend?
