ASUS Maximus Formula SE

[Majoram]

My Mobo temp is 38°C under full load at 3.6ghz ( 8 x 450 ), nb and SB temps around 40-45°c...

Is your case well ventilated ? becasue these temps at stock indicate something is lacking with your airflow, wich case do you own ?

I have the Antec P180. I think I will check things with my case open and see how it goes.

Full Specs:
Mobo: ASUS Maximus Formula SE
BIOS: Version 0505. All default. No changes.
RAM: 4 x 1GB PC8500 Crucial Ballistix
CPU: Intel Quad Core Q6600
CPU cooling: ThermalRight Ultra 120 Extreme (Dual Fans).
Video: eVGA 8800 Ultra
Case: Antec P180. Top and Rear fans set to exhaust. Front set to intake.
OS: XP Professional 32bit

Just checked my Memtest86+ v1.70:

25 passes, 7 errors:

In Red it says:
Test 6
Pass: 17
Failing Address: 0003c81e5cc - 968.8MB
Good: fff7ffff
Bad: fdf7ffff
Err-Bits: 02000000
Count: 7

Any idea what this means?

"Case: Antec P180. Top and Rear fans set to exhaust. Front set to intake."

Have you tried leaving the front door of the case open? I'm just looking at that case on Newegg and it doesn't look like you can get much intake with the door closed.

Yes the front door is open at all times. I'm gonna try it with the side of the case removed, just to see what happens.

PS: Would 4GB of RAM cause XP (32 bit) to be unstable? Just wondering. I have 4GB because I plan to dual boot to Vista. I know that XP only recognizes 3.5GB
