Performance Series? Can you mention the specific name? Depending on the ram chip, most people get between 230-240 with 1 gig of ram. I had 2*512 of OCZ pc3500 EB PE. I had to use Tictac's D10 4x4 Turbo BIOS, ran 2.8V through them at 3-2-3-10. Hit my boards max at 236 with the gig. That's the problem with the NF7, it doesn't overclock well with a gig kit in. I went with a 2*256 kit later, and I'm at 255 right now. I'd still go with a gig though, the high fsb can't compare to the gaming performance that you get from having a gig kit. Personally, look into some OCZ pc3200 plat. rev.2's that have the 2-2-2-5 timings. Get a gig of that if you can, because it has the TCCD chip in it. Excellent overclockers.
