is installing 24GB RAM ok in a 3 x 8GB configuration?

[caramelicecream]

Hi everyone...just wanna ask if doing a 8gb-8gb-8gb [strike]setting[/strike] configuration is ok?cause i currently have a DDR4 16GB(8x2) Ripjaws V and just recently my friend gave me a brand new Ripjaws V(8GB) stick same specs..is it safe to have a 8-8-8 setting?or will this ruin my system?

thanks in advance

It will run just fine, if all specs are the same for the 3 RAM modules they will be no performance issues, just be aware that you will lost the dual channel function.

The loss of Dual Channel can impact game or application performance. Unless you edit video there's probably no benefit to having more than 16GB anyway.

The actual loss might be almost nothing for most games, and over 20% in some demanding tasks but it would depend on the CPU, memory bandwidth, and program being used.

It's best to avoid the potential loss of performance especially if you have no need for more memory.

im doing both video rendering and 3d modeling/rendering...so is it beneficial for me to use a 24gb memory??im using a i7 7700 for my processor btw...im so sorry im not a tech guy but i really dont get the performance loss for the "dual channel"..so is it better to use the dual channel 8x2 than going for a 24gb memory??

Yes it is, most of the software used for rendering and modeling demands a lot of CPU and memory resources, I thing is a good call to use it and the performance you can lose in games is lower than the benefic you get in rendering/editin etc

It's difficult to say how much performance you'll lose. Possibly less than 10%, possibly close to 20% in some rendering scenarios but I doubt that for your setup.

A serviceable test would be to run Prime95, and monitor your CPU in the task Manager. If you're hitting 100% CPU usage then it looks like there's sufficient memory bandwidth.

I don't even know how fast your memory is, but for the above link it showed:

1) Handbrake was just over 4% slower in Single Channel
2) Adobe AE was 6% slower in Single Channel

I've seen higher but probably that was with slower memory. However, the CPU used for this test is a lot slower than yours (yours requires more memory bandwidth). I did look up other testing but the results vary so much between programs it's difficult to be specific thus you need to create a test on your own system like Prime95. Again, if the memory was too slow the CPU would be left waiting and thus couldn't run all eight threads to 100% usage.

*I would say the difference for you is probably small so there's no big need for Dual Channel, but it won't likely be nothing.

(FYI, the way Dual Channel works is that data is split between two sticks of memory thus you have 2x the potential bandwidth. However, how much bandwidth you require depends on how much processing the CPU is doing. Games rarely use 100% of an i7-7700. You really look at the worst-case scenario so Prime95 would be close to that. If the CPU can be shown at 100% usage then it's not bottlenecked by the memory.)

Also:
In video editing sometimes you are held back by the drive speed (i.e. SSD vs HDD). It depends what you're doing, how much system memory is used etc. That's beyond the scope of this though.
