1066 or 1333?

Whats the difference between the two types of memory and is it worth the 200 dollars to upgrade to 8gb 1333 or should i stay with 8gb 1066?

 

Still haven't figured out how to use Google huh?

Because I have sympathy for your ignorance of Google and your laziness, which I found in less than 5 seconds since it was the first search result...

Game benchmarks comparing DDR 1066/1333 and Latencies

Applications Benchmarks

Conclusion of the comparisons

 

Oh look the first search result for DDR+i7.

Isn't that amazing what information you find when you aren't lazy to type two words in Google?

DDR3 Round-Up: Core i7 Performance Analysis

5 Seconds to read, i7 does make use of speeds. The i7 720QM does support 1333. But conclusion showed a low latency 1066 would be on par with 1333 high latency. Latency seems to be a bigger factor than speed.

I feel like a parent spoon feeding a baby....

 

I was kinda looking for someones personal opinion. Thats why i didnt look on google. But thank you.

 

In day to day tasks, you won't find any differences between 1066 and 1333MHz ram speeds. If you have $200 to spare, it would be more beneficial if you invested in an SSD instead of the ram.

 

Okay thank you very much. Thats what i was looking for.

 

Yeah benchmark figures aren't always the best representation of what goes in real world. but the little performance boost as said above you won't notice. SSD or buy a nintendo ds or something..

 

Just chiming in that an SSD is a hilarious performance improvement.

 

Hilarious?

 

i dont understand whats so funny...

 

hilarious:
1823, "cheerful," from L. hilaris (see hilarity) + -ous. Meaning "boisterously joyful" is from 1830s.

Used in a 1830s style sentence:
I say old man, I just have to chime in and say that SSD is a boisterously joyful experience with a, jolly good performance improvement.
Cheers!

 

Lower speeds=lower latency. Buy a SSD like everyone else said.

 

That's not exactly true. RAM timings are measured in clock cycles, and the clock cycles are shorter the faster the RAM is.

For example, a CAS latency of 6 with 533MHz RAM is a latency of ~11.25ns, while a CAS latency of 7 with 667MHz RAM is a latency of ~10.5ns.

However, that doesn't really matter anyway, because faster RAM still makes little difference in Intel's recent microarchitectures, lower latency or no.

 

Opinion doesn't change reality and fact. Be honest, typing two words in Google, and then having to read the article was too much effort...
