Does RAM speed REALLY matter?

Now that we have RAM modules capable of up to 4266MHz, we need to find out... does high speed RAM ACTUALLY make a difference?

Buy DDR4 RAM

Ok, we need a remake, its been more than 2 years

Who needs performance when you got *RGB*

[GarbageTVoriginal]

Human eye can only see 4 gbs of rgb ram

Problem: RAM is SO FUCKING EXPENSIVE RIGHT NOW

I haven’t watched the video yet but I’m guessing he’s going to say it depends

Accurately reflects modern ram prices.

Imagine being Linus’s neighbours.
Looking out the window on a nice morning, taking a sip of joe.

And all you see is Linus going full crackhead smashing his keyboard all throughout the cul de sac.

I tried to explain to an old friend that faster ram doesn't really make a difference but he didn't believe me. This is the same guy who's buying two 1080ti for his 1920*1080 60hz display though...

Anyone else not know wtf was goin on in the graphs

When you find RAM that is RGB and it's the same price.

Who cares if it matters or not? IT'S FREE! All you have to do is download more!

I love how we can just refer to computer companies with Red, Blue, and Green, and PCMR will understand

The CPU eats 1's and 0's and poops out games, etc. Interesting way to look at

Speed matters, but it is dependant on CAS latency.
3200mhz DDR4 CAS-14 is pretty much the best thing commercially available right now.
As speed increases, typically CAS latency increases as well, so much so that something like 4266mhz DDR4 CAS-19 is actually SLOWER than 3200 CAS-14 memory.

You can do the math: [L/(0.5*S)]*1000=E
L= Latency (CAS),
S= Speed (in Mhz),
E= Effective Rating (lower E value = better)

So for 3200mhz CAS-14 ram the equation would be:
[14/(0.5*3200)]*1000=8.750

For 4266mhz CAS-19 it's:
[19/(0.5*4266)*1000=8.907

If you could get 4266mhz ram with a CAS latency of 18 THEN it would be slightly faster than 3200mhz CAS-14 RAM... unfortunately it doesn't exist (or is not actually available for purchase).

Hi Linus - My Commodore 64 only has 64kb of ram. Should I upgrade to the much more powerful Commodore 128 or does ram really matter? Please respond as I'm trying to get more than 16 colours while playing Flimbo's Quest. Thanks.

Remember when RAM was the cheapest component? Ah, those were the days.

That guy got scammed, Linus only gave him one stick.😂

[adamdanilowicz]

Can you make a video on keyboard over-clocking?

[tls]

Also instead of getting RGB Ram just get regular RAM and use more LSD and that problem will be fixed

[diamondninja]

Would be cool if there was a quick revisit on this
