ASUS Maximus Formula SE

[Fixxxer]

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?

ASUS MAXIMUS FORMULA has several problems with RAM. I have Ballistix PC8500 and I can't boot at 1200MHz (and my sticks pass superpi 1M at 1400MHz).
