First foray into overclocking a 1055T

[Global_Inferno]

So I managed to get hold of the following kit last week:

- Asus Crosshair IV Formula AMD 890FX (Socket AM3) DDR3 Motherboard
- AMD Phenom II X6 Six Core 1055T "95W Edition" 2.80GHz (Socket AM3)
- Corsair XMS3 4GB (2x2GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit

EDIT: Oops, I should probably mention what type of cooling I'm running; an Akasa Venom.

I've got it all installed and running Windows 7, and I'm starting to look at the OC potential of the kit.

So far I've managed to get:

- FSB: 250MHz
- CPU: 3.5GHz
- CPU-V: 1.325v
- HT: 2000MHz
- DDR: 1333MHz (as the 1666MHz divider caused it to fail P95 on stock RAM volts).

However, on an overnight run, one core failed on Prime95 (after a few hours) while the other 5 worked flawlessly.

I've only changed the voltage on the CPU, nothing else, so where should I be looking to go from here? Add more CPU voltage and try to get all 6 cores stable? Try to get the RAM working closer to 1600MHz? Do I need to increase the NB voltage?

I'm not too sure about what to do now!?

EDIT: I'll post some CPU-Z screenies later as I'm at work atm.

A quick update, I've got it running at 3.9GHz now, using the following settings:

FSB: 300MHz
CPU: 3.9GHz
CPU-V: 1.344v
CPU/NB-V: 1.75v
HT: 2100MHz
NB: 2100MHz
DDR: 1600MHz

And it's been tested with Prime95 Blend for over 4 hours, I'll probably give it an overnight run as well at some point. The 1055T would easily go faster too, however I don't want to push the temp's much higher than they are currently under full load (60*c~).
