DDR3 1333 will it work?

Didn't work when I tried it.

 

Make sure that it is the same number of pins / SODIMM form factor. It should work, but the speed the RAM is being run at is determined by the motherboard, not the stick of RAM itself. So even if you put in RAM that is rated for a higher speed, it will still run at the default.

 

Get it online, it should be much cheaper and you should be sure to get something that works.

 

Judging from the situation on Intel PCs (and from previous Mac models), if you put higher-clock RAM into a board, the RAM will work, but will run at the slower speed of the board, not at its capable speed.

Since 1333MHz RAM is more expensive, and wouldn't run at full speed anyway, it's unlikely you're going to find any concrete information about this particular scenario, since few people would bother.

 

That's how it works on any computer. The RAM, regardless of clock speed (when higher than the spec'd bus speed), will run at the bus speed.

 

I can't imagine it could possibly be any different than what these guys have said.

Save your money and get the 1067mhz DDR3.

 

If one says it definitely doesnt, and another says it might, I'd go ahead and assume you should just go buy the right type of memory.

 

Buy from newegg or tigerdirect, it will almost always be cheaper than a Retail/Big Box Store.
