Asus P5N32-E SLI - NB Core Voltage Settings ?

Hi Guys

What should the NB Core voltage be set at, in my BIOS I have it set to auto but I have just installed Asus PC Probe and it says 1.52V is this too high ??

I have mine at 1.45v (currently running at 3.4GHz).

mines at 1.45 as well I think - the NB on mine seems really unstable - if the NB heatsink is on too tight it will randomly lockup within 5 minutes of booting, if it gets too warm it will lockup within a couple of hours and if the voltage is much above 1.48 or so it will also lockup constantly

hence why I swapped to a Gigaabyte P35 DS3R for my gaming PC...

^^Yeah it's gets ridiculously hot.

Which is why I've ghetto modded 2 fans on the side of my case.

Mine ran on 1.55v no active cooling with zero problems, but I've lowered it to 1.5v now as it performs the same. Very very hot though, those heatpipes make me wonder. If it's running 1.52v by auto then that's fine, mine was on 1.55v auto.

So should I leave it on Auto then guys

If your not overclocking, just leave it on Auto.

I rather suspect that the NB is the root of the prpblems I've been having for the last two months, but I've been unable to prove it. Currently I'm at 1.50V, but dropping as low as 1.35 doesn't stop the problem - random gfx lockups. It's not the gfx themselves (three different gfx cards do the same thing).

As for the temp, the heatsink seems to reach about 50oC, suggesting the NB itself is about 10-20oC warmer than that. Not nice, but probably not fatal.

Q: Wasn't this board supposed to have a clip-on fan cooler included? Because if I got one I can't find it, and I can't remember if I ever had one (bought the board in March).

No it doesn't come with a clip on fan, but there is one designed for the MOSFET by Asus (heatsinks near the CPU).

I didn't get a fan. :confused:

Meridian · 18 Sep 2007 at 09:14

The mosfet heatsink gets just as hot as the NB one...

Wait a minute, I was thinking of my P5W DH Deluxe (as it comes with one).

P5N32-E SLi = no fan
Striker Extreme = fan

Sorry. I'm in the middle of revision and my brain is frazzled.
