did i get the right ram?

Last month I bought PNY RAM at best buy.(http://www3.pny.com/8GB-2x4GB-PC3-10666-1333MHz-DDR3-Notebook-SODIMM-P3018C321.aspx)

and ever since I've gotten this RAM and replaced it.
I've been getting kernel panic, and many other errors.

I'm using a mac book pro mid-2009 running 10.6.8

If you're getting kernel panics, it probably isn't the right RAM. If you put the stock RAM back in, do the kernel panics stop?

I actually have 2 x 4GB of 1333MHz RAM in my mid-2009 13" MBP, and it works fine. It actually runs at 1333MHz and I can honestly say I felt a SLIGHT improvement in my graphical performance. It's just Corsair value select that was on sale a couple months back for ~$30.

RAM that is rated at higher speeds does not run at those speeds if the FSB or chipset isn't set at that. It will run at the lowest speed of the chipset, in this case, 1066MHz. Apple's system just reports the designed speed of it; doesn't mean it runs at that.

Thats what I thought too, but when I boot into Windows 7 and run CPU-Z it reports 1333MHz.

Check again that it is the actual speed. Remember, the only way to achieve those speeds are through overclocking as those Intel chips are designed for 1066MHz not 1333MHz.

I'm very familiar with how CPU-Z works.

The mid 2009 13" MacBook Pro uses the nVidia MCP79, which supports 1333MHz FSB. I know most chipsets are able to run the FSB and the RAM out of sync, I'm sure this one can to.

Yet you still don't see 1333MHz because the FSB of the CPU is still at 1066MHz so for all speed that RAM has, you won't see it.

I have late 2001 MB Pro. I had the same problem. Took it to the Genius bar and they could not find anything wrong. It started after about 2 weeks. I returned it and put original RAM in and everything works fine. Just ordered from OWC and now waiting for delivery.
