DDR3 1066 worth it?

Now that I have my 2nd hard drive installed I am looking at the next feature I wanna upgrade. I have a G50V-X1, now going through the Device Manager and Asus website, it's sayin the chipset is a PM series as well in the device manager I'm seeing mobile intel chipset 45. I believe I was given 4 gig of DDR2/800 Mhz last time I checked. Now I'm wondering, I went through the intel site (which is the second link) and found the PM45 series chipset and under technical documents, then database it's sayin I can handle up to DDR3 1066.

My question is, am I looking at the document?
Has anyone done this yet?
If so is it worth upgrading to the ddr3 1066?
Will there be any overheating issues I would need to be worried about or any other type of issue?
I'm looking at Patriot 4Gig (2 sticks) mem. for 100.

Thanks for the help.

I do not believe your laptop can support DDR3 memory.

 

As Euquility mentioned, the G50 series can not support DDR3 ram.

 

The G50 series laptops, while they have the PM45 chipsets that can support DDR3 memory, are only built with 200-pin DDR2 slots. DDR3 ram SO-DIMMs are built with 204 pins, so it physically will not fit.

 

hmm lame, thanks for help guys

 

You can't stick DDR3 RAM into a DDR2 Slot, but it doesn't matter. DDR3 1066 from what I've heard has high latencies and you're probably better off with DDR2-800 for now

 

hm good to know

 

I wish Asus had equipped it with DDR3, but only because of the potential battery life gains.

 

You won't find any noticeable battery life gains w/ DDR3 compared to DDR2 in real life tests.

 

of course you will though it should be nothing to write home about maybe 5-10 minute gains on battery life.
