LinX with more than 6Gb of RAM

Using the latest Biostar bios, and using hw monitor and Biostar's monitoring utility to check temps. Just put a desk-fan blowing at the MB on full power and the temps peaked at 77c on stock settings.

Just put the 80mm fan on 2400rpm, ran linX, it reported 83c, touched the NB heat-sink and it was cool to the touch, almost no heat, so either it is not making proper contact or the sensors are talking rubbish.

It doesn't sound right like I said earlier the X58 chipset is just a PCI-E hub and I can't imagine it reaching that temperature unless the heatsink falls off or ridiculous voltages are somehow (bug?) put through it.

I can only think that maybe the sensor is for the VRM's which are being pushed harder with all the extra memory installed.

Think I have nailed it. After a linX run I had a feel of the memory, it was roasting hot.

(This is the GSkill ripjaws with the big heatspreaders)

Have now attached a 80mm fan right above the memory and the IOH? reading has not gone past 53c at stock settings. I am beginning to think the sensors on this MB are very strange and that maybe the IOH reading is actually both the NB and the memory chips.

Very very strange that doubling the ramsticks resulted in such a huge jump in temperatures, obviously with the sticks so close to each other they were getting no airflow.

It's not possible to monitor memory temperature.

I still think it's more likely to be some sort of VRM sensor if not a bug.

Hmmm according to Everest Extreme edition the temperature probe that is causing the problem is the motherboard temperature not the NB.

Apparently the probe represents the CPU socket temperature, I wonder how to try to cool that down

Well I was able to drop the temps at stock speeds using two fans but trying to run past 4Ghz just proved impossible due to the 88c temperatures on what indeed turned out to be the Northbridge. 12GB is running nice and stable at 4.2Ghz however, and the 6 spare GBs will have to be sold.

Thanks for the tips and hints btw.

You'd be better off replacing the motherboard then imo as Asus/Gigabyte etc have no such problems, it must be some sort of bug that is unnecessarily overvolting it.
