Is my parts bottleneck ?

I got A-data 800mhz

and I got an Q9300 CPU from intel and want to OVERCLOCK to 3.6ghz or 3.7ghz with aftermarket cooler

I try to oc it , but the max I can go is 3.2ghz 426 x 7.5 FSB 1.35v , memory @ 1023mhz 2:1 ratio 5-5-5-15 timing 2.1v ( default is 800mhz )

I got asus p5e motherboard

should I get better ram for overclock ?

I was planning to get

^ 1200mhz

or

http://www.newegg.com/Product/Prod [...] 6820231166

^ 1066mhz

which 1 should I buy ?

Thanks

Max i can go with my ram is 1066mhz , but it will auto reboot b4 loading into windows xp

Before you go off and buy memory first wonder if it's worth buying memory? In real life applications there is no difference between 1066 C5 and 800 C4. Also are you sure your memory cant go higher? My DDR2-800 modules wouldnt go above DDR2-1030 C5, but as soon as I set DRAM CLK SKEW to advance 150ps I can happily run DDR2-1200 6-5-6-15.
