i7 840QM - Temps only 2 cores

Recommended Posts

I did all my driver updates to my new ASUS G73JW A1.

AIDA64 can only show me 2 cores in the sensor menu, and sidebar gadget.

It showed me 4 core temp readings when I first installed... but now it shows only 2, even after AIDA64 re-install.

cpu : QuadCore Intel Core i7 840QM

Duno if these would help...

Have you disabled core parking in the windows registry?

Ok yeah I just tried that also, but still no change. AIDA64 still reads two core temps. Weird though, first time use it had 4, but now only 2.

It's a new laptop too, not even a month old.

I’ve been getting “Error sending end of post message to ME†messages at start up.

So I’m thinking that’s why the Date, desktop arrangements, are never saved, and are always changed when rebooting too... I don't know if this could be part of it. Thanks.

Indeed that could be the issue. The BIOS is unable to inform ME of POST end and that can cause several issues.

Possible solution: BIOS upgrade (with ME) or RMA

So I restored using the F9 feature, back to settings. then updated the BIOS from 202 to 203 successfully... booted into windows fine.

Managed to get online and post this, so it's ok. But the Error message is still coming up at boot up.

I guess an RMA? This doesn't really affect my work, but I'm just worred if it will give me problems in the future, or I just don't want no error msges.

Thank you for all of your help.
