How much more of an o/c do you want on your mem? lol. 8000 is already ddr2-1000.
are you trying to set a WR, are you using a 7x chip?
for most people the ddr2-1000 should be more than enough.
like i said before, i got some crucial ballistix 8000's that i can run 5-3-3 @ 600mhz 32M with something like 2.3 to 2.35 volts.
for 24/7 use, i run them at stock ddr2-1000 with 4-4-4 timings with 2.13-2.15 volts.
