Intel has had there share of ssd problems and their not the fastest, so I don't see how they could be the best. No one knows how long the actual life cycle of a ssd is, I have a 1st gen Agility and Vertex and they are still working great after 2-1/2 almost 3 years. Will they last for 10 more years? Who knows but right now there is not enough data to say whose drive will last the longest. What I do know is I have and or tested and gave away 7 OCZ drives of various models and I didn't have a problem with any of them and they are all still working.
I chose the Agility 3 over the Intel mainly because of the extra 40 GB's and then the speed, I chose the Agility 3 over the Patriot because of the speed.
It might be a heat problem.
Thinking more about your memory, what modules are you using? Are they all rated to run at the same Speed, Latencies and Voltages? Have you tried bumping up the DRAM Voltage a little when your using all of them?
I had a LGA 775 system that would run two sticks of DDR2 1150MHz just fine, but if I added two more sticks of the same memory it would only run at 1066MHz. I later found out that it was a limitation of my mobo.
