CL9 VS CL11, Extra CL9 Price worth it?

[Crafting]

Hey guys.

 

So I wanted to upgrade to 16GB of ram (don't tell me why I don't need that much)

And i saw these 2 deals.

2x8GB CL11 DDR3 462 DKK 

2x8GB CL11 DDR3 538 DKK

 

The DKK is the currency in my country, and it's around 12$ difference in dollars.

 

My question is, is it worth the extra money for lower latency?

Both are 1600MHz

 

I can't buy the same RAM stick as i currently have, since it is not sold anymore.

Not really worth the extra money for latency.

Just buy the CL11 kit and run it at CL9. 

 

easy peasy.

If you already have an 8gb stick, you can just add another one. Regardless of being the exact same or not, it'll work just fine. You can save some cash by doing that.

 

But to answer your question, no, not really.

Not worth it.

 

You wouldn't even notice if you bought the better kit, built your computer, used it for a month, and then I sneakily switched out your kit for the slowest DDR3 kit i could find.

both run at CL11 no difference

no difference, get the cheapest

If you are going to be spending large amounts of time doing massively memory intensive operations - e.g. video encoding and such -  then yes the latency matters.

 

For all other mortals, not so much.

 

The chart on this page will tell you what the differences work out to be for every given RAM speed.  Yes, those differences are fractions of nanoseconds.  But given enough operations those nanoseconds can add up to real time differences.

You want to try? My eyes sees 144 FPS, and my calculating speed is faster than a Commodore!

Ahh, thanks alot.

 

But the DDR4 Memory having latencies much higher than standard DDR3's is a bit weird, but I guess the increased standard frequency acoomodates for that.

Latency, in it's core, it's a difference in time, measured in seconds. However, the advertised "CL9" actually has no correlation to that. What it is actually measuring is the number of cycles, not the fisical time in s.

 

And why am I telling you that? Because there's one little difference between DDR4 and 3: the cycles are "faster" in 4 than in 3. This means that, while DDR4 seemingly has higher latency (so it takes longer to respond), the reality is that the actual time is around the same as DDR3, and sometimes even faster! In other words, actual latency is just as good, if not BETTER than DDR3!

Heya

 

I saw one key difference, between the RAM I have, and the RAM available on the market.

 

The RAM I have is PC3-12800 or something like that, and I can't find any others who have that number, is the number irrelevant in my situation? Can I just mix PC3-12800 with PC3-xxxxx? or is there a small margin I have optionable?

PC3-12800 is just another way of labeling DDR3-1600mhz. DDR3-1600 refers to the speed the RAM runs at, whereas PC3-12800 refers to the actual transfer rate of 1600 RAM (1600*8=12800).
