I wanted to find out if anyone else has experienced/noticed this.

I have an ASRock H67M-GE with a i7-2600, 16GB of RAM, a simple 750GB Barracuda ES (enterprise) hard drive, all powered by a Seasonic SS400FL (400watt, 80 Plus Gold) power supply.

OS: Natty Narwhal 64bit
The test app: "mprime" from mersenne.org running Stress Test, #3.
With the motherboard that was recalled, the power consumption maxes out at 105-107 watts

With the new B3 replacement motherboard I got today, the power consumption under the same tests runs at above 135 watts (a jump of over 25%).

Anyone else experienced this lil' oddity?

I'll try to tweak the BIOS tomorrow since the I was in a hurry and only did basic tweaking.

Only other difference is the thermal compound (I ran out of my AS matrix and had to use the venerable AS5).

But still....25%?
