I am running a MSI P67A-GD65 (B3) LGA 1155 board with an i7 2600k cpu, not overclocked.. I currently have 2x4GB DDR3 1333 (PC3 10666) 7-7-7-21 CAS Latency 7

Would 2x4GB DDR3 1600 (PC3 12800) 8-8-8-24 CAS Latency 8 be an upgrade?

As I understand it, the timing/latency on the 1600MHz is slower, but the transfer rate is higher at 12800. What would be the difference in performance?

Im interested what others have to say as I dont have an opinion of my own. Still working out the differences between the two though for all my own stuff I prioritize RAM voltage and latency over clock.

 



But... I did find some helpful articles.








"Knowing all of these results, it is obvious that highest speed DDR3 memory only makes sense for serious enthusiasts, or for those with unlimited budgets. Everyone else should focus on mainstream clock speeds of DDR3-1066 or DDR3-1333, and go for a trustworthy brand and the quickest timings their budget allows."








"We tend to favor running low-latencies at any given memory speed to ensure the best possible performance and as such we tend to stray from any of the CAS8 or CAS9 kits below DDR3-1866, unless they are capable of running much lower timings on like voltages."




"You really do not give up that much performance with DDR3-1066 when compared to the more expensive alternatives and that is a good thing to know when putting a system together on a budget. As such, there is still great value in using it."

You might be able to tell in benchmarks, you wouldn't be able to see the difference in games.

There's no point in doing that. Better off putting that money to a better graphics card or SSD if you are looking for an upgrade.

In reality, not much.

For example, my friend has DDR3 1600 at 9-9-9-24, and I have DDR3 1800 at 10-10-10-27, and performance is virtually identical.

Thanks for the responses guys, looks like there won't be any significant advantage for me.

beavo451 - My intention wasn't to go out and buy this as an upgrade, I already have the extra RAM from another project.

Thought about just popping  those in alongside my existing RAM but I hear that may potentially cause issues due to different MHz and timing.

Wouldn't hurt to try it. It should run at the slower speed and higher timings.

In games you won't see anything.  In programs outside of games, maybe second is saved here and there.  Only into the high 2,000's where it will cost you hundreds of dollars worth of ram will you notice anything.

RAM is only as strong as the weakest link





Meaning...it only runs as fast as the slowest clock and highest timed DIMM
