I picked up a Corsair 4gb (2x2gb) XMS2 DDR2-800 set today. My board is an XFX with the nVidia 610i chipset (two DIMMs), and it supports up to DDR2-667. The ram auto-tuned to 667 when I booted up, and it runs Vista 64 and UT3 better than my 2gb 667 stick did, but I'd love to get it "overclocked" to stock speed. The stickers on the ram say a timing of 4-4-4-12 800mhz, and they're defaulting to 5-4-4-14 at 667. My processor isn't overclocked or anything, just a Pentium Dual-Core E2200 with 800mhz fsb.
To get the ram to 800mhz, can I just change the timings, or do I need to increase voltage? How much risk is there in this kind of adjustment?
