Unstable after RAM upgrade

I installed 4GB of Patriot RAM from Fry's. The specs are:
2 x 2GB, DDR3 PC3 8500
Model: PSD34G1066SK
This is the same set at newegg:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820220338&Tpk=psd34G1066SK
During various operations, including SuperDuper, downloading files and watching YouTube, the machine froze and I had to restart by holding down the power button.
I've run memtestosx in single user mode and it didn't turn up any issues.
Should I return the RAM and get a replacement set? Should I go with a different brand?
Thoughts?

One quick correction: Looking at the superduper log, it seems that the backup was completed before the crash, which means nothing but the screensaver was doing anything interesting at the time of the crash.

After several crashes today, I decided to do a clean OS X install, hopefully ruling out any software problems. The computer froze approximately 3/4 of the way through zeroing out the HD.

Swapped in the original 2GB. Everything seems fine. Guess I should have bought online and gotten the $150 2GB upgrade. The Apple Store tells me it would cost $400 to have a genius do it.
Has anyone successfully upgraded the RAM with something off the shelf?

Have you tried reinstalling the new ram? Perhaps one of them was not seated properly the first time around.

That's one of the reasons I buy Apple branded memory.
I usually buy brand new pulls from new machines.
Placing like OWC etc. sell brand new pulled memory modules from new computers that customers are upgrading the memory on. Check around on the net.

I swapped the 4GB back in and I'm testing now. I'll leave some video and audio running overnight and see what happens.

Thoughts?
If it's less hassle you could try a replacement set from the vendor first. If that doesn't work then try another brand. As with everything else no brand is perfect and it's quite possible to get a bad one.
Just curious, what brand of memory comes with the new macbooks? My iMac came with Hynix but replaced it with 4GB of Kingston.

FYI... if you buy your RAM at OWC, they will give you $15 for your OEM 2GB RAM chips which knocks the price down to about $125 for their 4GB kit which is warranted for life.

Hi!
I'm planning to buy the MacBook aluminum soon and would like to upgrade the RAM with the RAM I got for my current PC.
Do you think these specs will do the trick?
Corsair Value Select SO DIMM DDR2 PC5300/667MHz 2GB VS2GSDS667D2
No the new MacBooks use a DDR3 RAM.

FYI, resetting PRAM and NVRAM did not help.

I don't see a brand name. There is an M symbol with a slanted oval around it... Maybe that's the manufacturer's logo?
