That is a very good improvement. Have you tried to lower your 1.45v
@ 3150mhz to see if it may be stable and possibly get your CPU temps
down a bit? That would give you a great OC for the E4300. Even at 72c,
if that is the absolute max temp, isn't bad at all if it stays stable.
Orthos with small FFTs seems to stress my E6600 more than anything I do
including A/V rendering and much more than 3DMark 06 or any
gaming/simulation. I would doubt that you would ever see 72c with any
apps you might run in normal usage. I am really interested in seeing how
your CPU will OC with liquid cooling. Are you still thinking about doing
that?
I found that after running my system a few weeks that my temps
gradually creeped down and I had to add a couple of ounces of coolant. I
may have had a little bit of air that may have been in the system that
gradually worked it's way out. I am going to install the Striker Extreme
that Asus sent me to replace the P5N32-E-SLI that the SATA contoller
died on. We had company over the weekend so I didn't have any time to do
it. I am not sure I like all the bells and whistles of the Striker, but
I will give it a go.
