One of the RAM sticks could be problematic. It's been known to happen.
For this discussion, we'll call the new sticks A and B, arbitrarily.
Remove stick B and see how things go. If it doesn't panic, then stick A is probably good.
If it does still panic, stick A is suspect, so remove stick A and put stick B back in. If it doesn't panic, then we can assume stick B is good.
Now, if one of the new sticks A or B is suspect, leave it out for a bit and put one of the original sticks with the probable good new stick. If the machine panics, you may have a memory slot problem. Hopefully that is not the case and you can now contact OWC to get a replacement stick for the one that is causing the panics. One good thing (of many, IMHO) about OWC has been their customer service.
As an aside, you probably want to repeat the troubleshooting process at least once with each new stick just to increase the confidence in the result.

To eliminate RAM being the problem, Look at this link: Testing RAM @ http://guides.macrumors.com/Testing_RAM Then download & use Memtest & Ramber.
Do you have an Apple Hardware Test disc (the AHT is on the Install/Restore DVD that came with your Mac)? Running the Apple Hardware Test in Loop Mode is an excellent troubleshooting step for finding intermittent hardware problems. It is especially useful when troubleshooting intermittent kernel panics. If Loop Mode is supported by the version of the Apple Hardware Test you are using, you run the Extended Test in Loop Mode by pressing Control-L before starting the test. Looping On should appear in the right window. Then click the Extended Test button.The test will run continuously until a problem is found. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure.In some cases, RAM problems did not show up until nearly 40 loops, so give it a good run.

I installed some new RAM from OWC a few months ago and, as with the OP, things seemed fine. Then I started getting Kernel Panics with the time between ranging from just a few hours to a few days. Initially I didn't think it was the RAM and strted gettinmg help from people regarding my panic logs. I de-intsallled Sophos and Parallels for example and thought I was ok but no, the panics came back but I could go a day or two with everything ok.
I ran memtest from the command line and also the GUI version - member. I did 5/6 passes with each and both RAM chips passed.
Because I kept getting Panics I finally decided to take the new chips out and put the original chips back in. For nearly three days now things are fine. I'll give it a few more days then look towards OWC for some refund I think!

Your post is interesting to me. I tested with memtest and member but with only 5/6 loops. Both chips passed but panics continued. Swirching back to my old RAM appears to have fixed the problem...so I'm thinking my new RAM is faulty although, as you point out, discovering that is not simply a case of running the Loop a few times ..
