Thanks for your post. I suspected as much but thought I would post anyway given that all my hardware is spanking new.
I did call OWC to ask if they knew of the issue and if they had any work arounds. The tech that I spoke to claims that no one has reported the problem. I had him search their knowledege base for the words "filker" and "thunderbolt" and he found no hits.
I know other users have had discussions with OWC (i purchased 24Gb of RAM from OWC) but it seems they have not taken notice. Here is what I got from OWC to no avail...

I recommend trying to clean the memory module. Take a clean pencil eraser and gently rub it along the metal contacts on the memory and follow that by using a microfiber towel along with rubbing alcohol to clean the metal contacts on the memory, this should insure that the memory is getting a solid contact with the computer
If that doesn't resolve the issue, I would try both and SMC and PRAM reset.
SMC reset: http://support.apple.com/kb/HT1411
And
PRAM Reset:
1) Start the machine while holding down the Option-Apple-P-R keys
2) Wait until you hear the 3rd startup chime, then let go of the keys and let the machine boot up.
Lastly if the issue is still unresolved, I recommend running an application called Rember. Rember is a free download at http://kelleycomputing.net:16080/rember/. Once you have it downloaded please run a 3 pass test. This application will let us know if any issues are present on the memory modules.
I look forward to your reply.
Sincerely,

I guess I will need to live with the flicker for the next 6 years (that is how long I had my mac pro) and then be a bit more carefull when I purchase my next system.
