Question; 8 of one or 16 of the other? (1333 vs 1866)

Which would be more useful, 16 GB of 1333 ram, or 8 GB of the Kingston 1866?

I'm thinking that 8 GB of the 1866 (assuming it will run at that speed) will do more to speed things up than the 16 of 1333 will work more efficiently, because more than 8 GB of ram is wasted, or so many people say.

BTW, I use Photoshop CS5 a lot.

What do you think?

if you use photoshop a lot IMHO it would be more useful 16gb of ram
My work is Adobe CS 5 photoshop, illustrator, dreamweaver, fireworks, a lot of flash and premiere! YOU WANT 16GB RAM!

+1 I definitely think more RAM would have a much greater impact.

Maybe we'll get a BIOS to make 16 GB of 1866 work at full speed..... 😄

More is better. Unless you're also upgrading the hard drive to an SSD, you'll be exchanging fast memory reads/writes for slow (very slow) reads/writes to disk cache. With 16GB in my computer, it doesn't have to ever write to disk cache, so everything is loaded into memory and available almost instantly.

Summary:
1) For Sandy Bridge, higher memory bandwidth (i.e. higher MHz rating of your sticks) does not translate into meaningful real-world performance
2) For SB, lower CAS latency does not give any real world advantage over higher latency (ahem, cheaper) counterparts
3) There is no value in more expensive memory kits on the Sandy Bridge platform.
4) Sweet spot is 1600 MHz for SB's memory controller. A slight performance gain is seen going from 1333 to 1600 MHz DDR3, but going from 1600 to 1866 nets you essentially nothing in real-world performance on Sandy Bridge.

So, if someone has 4x4GB sticks of Kingston's 1600 PNP DDR3 and all 16GB runs at 1600 MHz in the G74SX, I'd buy that stuff.
Me personally I have just bought 16 Gb of Samsung 1333 CL9 stuff for my G74SX.

Definitely 16GB of 1333, I've run an 8GB box out of memory with Photoshop. 🙂

CS4 I bet. lol It was less memory efficient. But still, my daughter used to run CS4 on 4GB and never ran out of mem. What did you do to max it out?

Doing HDR or other photo merge processes sucks up tons of memory since it has to load all the images at the same time. Of course, it helps to resize the source images before doing this but even without doing this my source images are less than 20MB each and when I run the box out of memory it was merging 8 individual images, so on the face of it it didn't seem like it would use much but Photoshop killed it.

it sure was nice to have a bios update to support 16gb 1866 or even 1600.. or even 32 gb.. in the next 2 years i would buy 32gb..
