My water cooled GTX 280 story.

I wanted to make an update boy's...

I found the program LinX which runs the IBM LINPACK Test I believe...
It is a CPU heat generating monster for sure, and a stability checker all in one.

It didn't like my 3.8GHz setting, even though Prime and OCCT passed fine.

I set my FSB back to 414 to give me 3.7265GHz, as reported from cpu-z.

I lowered my BIOS CPU voltage to see the lowest that 3.7GHz could run LinX successfully.

BIOS voltage 1.48125v failed in Prime given 25 minutes.
BIOS voltage 1.48750v failed in Prime given 43 minutes.
BIOS voltage 1.49375v passed Prime and OCCT, but would not run a LINPACK Test error free.
BIOS voltage 1.50000v, or 1.48v in Everest runs everything I throw at it including LinX.

With me running at 3.7GHz, and lowering my core voltage down from 1.53750v in the BIOS to 1.50000v, my GPU idle temp reads 37C.
I consider this good given the CPU load that is on the system.

I think the entire temp of my loop likes the lower CPU voltage?

63C was the highest temp any CPU core hit during this test...
