Newbie looking for OC help

Hey all,

I've been tinkering with OC for the past couple hours and feel I'm at a bit of a stopping point as I haven't done anything manually yet. All my OC has been through windows using tools. I'm hoping someone who has this hardware and/or is familiar with it, can point me in the right direction to as exactly what I need to do and where it needs to be done:

- AMD Phenom 1090T black edition
- ASUS Crosshair IV 890FX
- ATI 5870
- 8gb (4 x 2) DDR3 SDRAM DDR3 1600 (PC3 12800)
- Noctua NH-D14 CPU Cooler
- 1000w PSU

So far I've done the following:
- Pushed the OC and unlock buttons on the front of the motherboard
- Hit 4 on computer start to unlock cores
- Ran the ATI Overdrive utility to go to 900/1300
- Ran the Turbo V Evo auto-tune which took me to
CPU Freq: 232
CPU Volt: 1.35
CPU/NB Volt: 1.15
DRAM Volt: 1.6
-- I bumped it up to 250 ok, then 260 BSOD'd me. I found posts where people were able to achieve over 4ghz, but you have to up the multiplier. This is what made me stop as I'm not entirely sure how to do this as it sounds like it has a dependency on the memory? I'm really not sure ... I'm still reading though.

I realize I have a lot of learning to do, and there is plenty of info out there. As I said though, I'm hopeful to get someone's attention that is familiar with this setup and can kind of just point me in the right direction in regards to what has to be done, and how far I can push it. I'm just very fearful of ruining my system as I've never dabbled in the OC world.



Thanks!
