Does Cas Latency Matter?

I was shopping for ram, and I accidentally bought 11 cas latency ram. I was planning on buying cl9. Will it make a difference when gaming? If so, I will return the ram and buy cl9. The ram is Patriot viper extreme 8 gb 1600mhz if that helps.
Thanks

Anyway, I think it is pretty clear, lower CAS Latency is bad. It depends on if you can still get your money back on the sticks, but it is worth it. If my 16GB of ram was CAS 11, I might not notice it (as much) but with 8GB I would want more speed, especially when running memory intensive applications.

It will be slower. The latency is how fast the RAM executes. I would return it and get CL9 for the same price.

Does it matter? I guess it depends on how important this is to you. If you were to run a synthetic benchmark it would be able to tell the difference. If on the other hand you took two identical machines, with the only difference being one had memory with cas 9 and one had 11, no, you wouldn't be able to tell the difference.

That depends on what you do, if only running a single app at a time, and not memory intensive, then prob won't tell, but that's a favorite test of mine and use with my clients quite often, same system(s), OCed the same, only difference is the DRAM (and it's sight unseen as to which DRAM is where (or when) and over 85% like the setup w/ the faster sticks ;)

I'm sorry, but there is simply no way that your clients (or you for that matter) can tell the difference, really world, between a system running 1600mhz cl9 vs 1600mhz cl11. It's a difference of 2 billionths of a second.

Put them side by side and run video, muti tasking, etc, yes you can, it generally takes a heavy user and one that is used to high performance, but you will see/sense it's running faster. If you're a gamer you might see a couple frames a second, but if you really USE your rig and know it, there's a difference. From the looks of your CPU-Z, try running your DRAM at CL13-15-15-33 and you two might notice, if you really use the rig
