I'm upgrading my PC and planning to continue using my old RAM.
I am getting i5-4670K, Sapphire R9 280X Dual-X, and Asus Z87-A.
My current RAM is 4 dice of 2GB each, DDR3 1333MHz, CL 9, tRCD 9, tRP 9, tRAS 24, tRC 33, CR 2T (noname from Dell).
If your mobo can support the 4 sticks go for it! There will not be a huge difference in speed and if you are building it for gaming you won't have problems because gaming doesn't use all that much ram. I would keep the sticks you have now and spend the extra cash on something else! Hope this helped!!!!
Nope, he linked some G.Skill 2133 and wants to know if it will give a performance improvement over his current 1333. He doesn't need to OC the CPU to run that 2133 memory on an ASUS Z87-A (great board by the way). I've built a half dozen with that board and its just a quick memory bios setting.
I agree that you should see a performance increase. HERE is a good article on memory speed and timings and you can see the increased performance of 2133 over 1333 at CAS9.
Thanks a lot for an informative read!
According to that article, increasing memory speed and/or timings brings no noticeable improvement for single-GPU gaming:
While memory speed did not necessarily affect our single GPU gaming results, for real-world or IGP use, memory speed above these sinks can afford a tangible (5%+) difference in throughput.
Of course, cost is a factor – price raises more with MHz than with tCL, thus the ‘work benefit’ analysis comes in – if buying a kit boosts your productivity by x percent, how long will it take to recover the cost? In single GPU gaming, for our setup, the benefits seemed to be minimal, but I can see workload improvements going for something faster than 1600 C9.
Since I am going to use a single GPU, my money is probably better spent elsewhere?
Yup, that is the conclusion for gaming. My guess is that for gaming the bottleneck was somewhere else (most likely the video card), although I would think that some very new games like BF4 might show some difference in performance, but that's just my speculation and memory is currently pretty expensive. You can revisit the idea of the 2133 when the price comes down since you already have the 1333.
