I have no idea what Blast QE

I have no idea what Blast QE is.  Certainly not a distributed computing project. There are no BOINC applications that leverage a Cross-fired or SLI'd gpu configuration that I know of or heard of.

I wanted to update the

I wanted to update the community on the results of my tweaking.  I accomplished the goal of reducing the temps in my hotter running GPU card with a combination of two things. 

I reduced the peak core voltage of the hotter running GPU from the default of 1.15V down to 1.1V using Afterburner.  If I go any lower, the card starts to become unstable and crashes.  This helped reduce the GPU temp across all w/u types.

The other thing was, I robbed some CPU computing power from the 1.22 G/R w/u when they run.  I had the utilization factors set for 0.5 CPU and 1.0 GPU.  Using those factors, when running 2 G/R w/u, 1 of my 4 CPU cores was set aside to assist with the GPU computing.  I changed the CPU factor to 0.3.  Now the system doesn't set aside a full core.  It does take a little longer to complete a G/R GPU w/u, but my temps are more reasonable.  I'll accept that trade-off.

OBTW, I still have crossfire disabled.

Thank everyone for their help.

OOPS!  Sorry wingmen!Just

OOPS!  Sorry wingmen!

Just looked at my completed w/u.  I seem to have a bunch of Validate Error w/u isolated to the computer in question (12771426).  I bumped up the under-voltage on the one GPU card to see if that solves the issue.  Keeping my fingers crossed.

EDIT!

OOPS again!

Looks like the issue was with #2 GPU card.  I may have over-clocked it a little too much.  Dialed it back a little.  Lets see what happens.

Solved!!!  Corrupted GPU driver update!
