I usually start at 1000MHz first at stock voltage then 1100 at stock again if not raise voltage. Thereforth and so on.
My first 7850 would crack 1450MHz mem but not the second one ... i RMA'd it at least it gave me a card with a full 10C lower temps

this is mine at 1002/1503 just running the benchmark settings..

for testing use heaven 4.0, 3d mark 2013, valley 1.0. once you arrive at stabe max clocks test in games. if you are not stable in games reduce clocks a bit to find 24/7 game stable clocks.
Thanks for the help guys. I currently have it set to 1200/1600/1200 on Trixx (core/mem/volts). Heaven 4.0 for benching.
It seems stable, until I got very minor and rare artifacting in BIoshock. Would you recommend upping voltage, or lowering a clock?
My system is:
Asus M4A79XTD EVO
Athlon II 630 (my 965BE @ 4.0 died last night, so I have to RMA it) - will this low end CPU bottleneck me much in Heaven or BF3?
4x2gb 1600 cas8 (ocz black edition)
Samsung 840 250gb SSD
X-Fi Titanium HD
