AMD Radeon HD 6990 Review: Sumptuous Dual-GPU Power

I think it simply comes down to being unable and unwilling to put in the hard yards is setting up the system. Most of my customers realize that they can auto-overclock, and most also realize that it isn't conducive to long-term system stability (or longevity)- but when they see me spend 30-100 hours fine tuning the system for overclock and low voltage, trying out different RAM timings, cooling orientations/combinations etc. I think they get a little overwhelmed but still want to put their mark on the machine -if you know what I mean. Some sort of proprietry statement.
Consequently I get emails from customers who push the boundries a little further and are elated that the system boots into OS. All good, as I always leave a little performance on the table. Unless I'm water cooling or using a chiller I never push a system to 100% if it's going into the hands of someone who will seldom if ever open the panels to clean the damn thing- unfortunately, a little success makes the budding uberclocker somewhat reckless.

BTW that HD5970 is basically toast. I told the owner to remove the card and give it a blast of contact cleaner every once in a while to clear the cooling chamber blocks. Not only did he neglect that chore but cooked off the VRM's. The screenshot is a furmark run I did AFTER I backed the clocks down- he had them at the stops on the right hand side.

I believe he was trying for the Minnesotan Overclocking Technique

....ummm helloooo!

****How about this here critter? I came across it today.

Are you using it ? ( the app, not the GPU as space heater! )

Not yet, just found it. I am going to see if I can patch CF for FM 1.8 (The multi GPU version would never run more than 2 GPU's)
