Hi I'm newly build 1 PC with budget of RM3k

i5-8400, GTX 1050Ti, 8gb 2666mhz RAM, casing, motherboard asus B360M-K and others adapter/PSU/misc..

Right now i feel 8gb RAM is fully utilized and i plan to add 1 more RAM on my motherboard. my motherboard got 2 slot and able to support up to 32gb ram..

However, i plan to add another 16gb RAM and make it to 24gb.. But whether it isnt okay to do so or must be 8gb + 8gb? can i have 8gb + 16gb?

as a person working wit big data there not enough ram in the world (plus gpu memory)...
other than that its fine...

suppost no problem as long as same speed (mhz) RAM.

Simple answer:
No problem.

Elaborate answer:
The RAMs can have different clock but the mobo will down-clocked the faster RAM to follow the slower RAM speed.

More technical answer:
Mixing RAM might not work properly if you have RAM with different timing. Those RAM should have same CAS latency, timings and recommended voltage. However, this is not guarantte that you will experience BSOD (blue Screen of Death). The RAM might hate each other or your mobo might prefer the other RAM.

So, the safer bet is to have both RAM from same maker as well.

You can mix and match the ram but just to take note that the motherboard will only take the slowest speed among the mixed of ram kits. For example now you have a 8GB 2666Mhz kit, then you have another 16GB 2400Mhz kit, the motherboard will only run BOTH ram at 2400Mhz instead of 2666Mhz speed. The ram speed is not much noticeable in real world performance as the capacity is much more important..

All of the above =D

My 24GB of RAM is 8+4+8+4 with 3 manufacturers =D

been running 24/7 for the past year, no prob even when 90% RAM Usage =D

It called dual channel or quad channel?

Haha, should be dual channel, for both pairs.

(8+8 and 4+4)

I did manually go into the bios to match ALL RAM timings
to the slowest (after it boots up and you can check and compare the auto-detected settings),
for banks A and B, for better stability.

Of course i will get same brand and same speed 2666mhz DDR4 16gb to match with my kingston 8gb 2666mhz ram..

too bad i'm not sure whether got any impact or not.. my friend told me to get another 8gb will do.

so your experience tell that 8gb + 16gb in same speed should be fine right?

Yup.

Timing will be lowered to the common one as well.

Did you run TASK MANAGER to check how many % of your RAM used?

Also run TASK MANAGER to see whether you have any other resource hogging applications in the background.

If you feel the computer is sluggish it doesn't necessarily mean your RAM is an issue.

Also, are you using HDD or SSD?

This part unfortunately is only relevant to Intel systems, which fortunately this thread is Intel related.

On AMD systems, the RAM speed and timing will affect performance.

90% of my ram occupied.. Actually i bought to play game & install emulator.. it hog a lot of RAM from my PC.. then i want play PUBG & Chrome.. Actually no lag performance issue yet, just wonder whether it isnt good to make my PC RAM always at 90%

At 90% level, good time to add more RAM.

See the result of this benchmark and which applies to you.

Is the 90% at idle or when doing things? When you have small amount of RAM it is advisable to run single big task without having any other big program eating your RAM at the background. Means if you play games, don't let Chrome running in backgound, you know from all the Chrome meme floating around it eats tons of RAM.

I too have 8GB of RAM, I tweaked Windows 10 to eat around 1.5GB-2GB RAM at idle and even so I still don't have any other background processes when running games. The only game that maxes out 8GB RAM is Rise of Tomb Raider and Shadow of Tomb Raider, this is with Vega56 with 8GB of VRAM. I can't run them at maximum detail even at 1080p, it would run for a while before some background processes started to crash because lack of memory.

me running android emulator for Ragnarok M Eternal love. I just ran 2 emulator and basically already 6.5gb/7.9gb of my ram.. if i open chrome then almost max it out.. hwoever, the performance didnt slow down yet.. I will play PUBG through steam with medium graphics (closed chrome). also max out.. if i going to record the game definitely will feel the laggy.. that's why i plan to topup with another RAM somemore.

even on none apu also have an effect?

Recording in real time is resource intensive, you need a beefy system to record in real time without lag. reduce quality and resolution helps as well.

i have 8GB ram. No problem running RotTR at 1440p with my GTX1070. No crash.

Everything on ultra?

Yes.

Show me memory usage when playing it?

Sorry. I already uninstalled the game.

Not sure if relevant for AMD RAM speed,
Left, 840 EVO with RAPID mode enabled, right is 960 EVO, RAM speed is 2400/2666mhz


840 EVO, Ram oced to 2933MHz, it's whooping 960 evo ass, i dont use the SSD much except when playing Doom, because the capacity is too small for another game lol

5.3GB. everything ultra at 1440p except using SMAA,
SottR use much less RAM though.

5.3GB for one game plus background processes really very close to 8GB limit so the recommended of 16GB is true.
