    Did you change the timings to match the bandwidth ? I very much doubt you'd manage 936 on 4-4-4-12 @ 1.9v.
    Have you run Memtest86+ to ensure the RAM is stable at DDR2-800 and default timings ? If so, I would suggest you loosen off the timings to 5-5-5-15 (you can leave the advanced settings on Auto to start with) at DDR2-936 -you may also need to bump the voltage. Try with 1.9v first and if the RAM stalls out then you'll need to go to 1.95 (or higher) although with loose timings you shouldn't need to crank up the voltage to high.
    The G.Skill Pi kits might look the goods but they're not the best overclockers. DDR2-1000 at standard 5-5-5-15-2T should be attainable, although DDR2-900 at 4-4-4-12 would give better performance. The main difference here is that your Static Read Value (also known as tRD or Performance level) could be tightened up from 9 (in DDR2-1000) to 7 (in DDR2-900).
