Gigabyte GA-MA790FXT-UD5P Thread

[Akamu]

Hey wutup, I'm new here and after reading a ton of reviews along with this thread I bought this UD5P board.

Couple of questions:

1_/) I would like to know if it's possible to overclock to 4.0ghz stable with DDR3 G.Skill ram (2 gig sticks 4gig total)?

2_/) If I increase the NB frequency will it keep me stable at 4ghz?

Here is my system specs and my overclock:

CPU - AMD 955 Phenom x4
Heatsink - Megahalem (switching to Megahalem shadow)
Mobo - Gigabyte UD5P
Ram - Blue G.skill 2gig sticks (4gig total)
HD - Caviar 500gig blue 16mb cache
PSU - 1000watt ultra x3
Case - haf 932
GPU - GTX 280
Dvd drive - sony
OS - windows x64 / windows 7 rtm 7600 x64


Overclock:
(I don't have pics because I'm waiting for the heatsink, so I'm going off of memory)

955 Phenom @ 3.8ghz with 1.44volts
Bus Speed = 200mhz
HT Speed = 2000mhz (bus/ht speed is at stock I did not touch them or the ram)
Ram Timings = 9 9 9 9 30 (I forget the rest but it's at stock)

Idle Temps 29c
Load Temps 45-46c
(The Ambient Temps were from 60-70c It was in about a month ago when it was hotter)
Primed 95 for 3 hours stable


955 Phenom @ 4.0ghz with 1.55volts
Bus Speed = 200mhz
HT Speed = 2000mhz (bus/ht speed is at stock I did not touch them or the ram)
Ram Timings = 9 9 9 9 30 (I forget the rest but it's at stock)

Idle Temps 31c
Load Temps 47-49c
(The Ambient Temps were from 60-70c It was in about a month ago when it was hotter)
Primed 95 for 5 minutes then blue screen'd

I noticed when I up the gighertz to 3.9 to 4.0 the computer start-up stays pitch black longer right before the desktop screen shows up.
