Do RAM speeds actually matter

Me having an OEM PC with RAM speed locked at 1333mhz, does it make noticeable or significant differences when using a higher speed? I can't upgrade my RAM or overclock because of it being an OEM so I just wanted to know if im missing out on anything because I've seen many videos showing a 20-30 fps increase with 2400mhz and other videos showing 0 increase in performance so I'm not sure .

 

My processor is a non k i7 2600 and my gpu is an RX 570 4gb

Memory bandwidth matters in gaming, higher frequency equals more bandwidth. Dual channel, of course, also increases bandwidth, so if you are only using one dimm a second one will improve performance.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

Dual-channel matters more than speed IMO

CPU: AMD Ryzen 5 3600  Heatsink: ID-Cooling Frostflow X GPU: Zotac GTX 1060 Mini 6GB RAM: KLEVV Bolt 3600Mhz (2x8GB) Mobo: ASUS B550-F ROG Strix (Wifi)  Case: Fractal Design Meshify C PSU: Deepcool DQ-M-V2L

at ddr3 , which is your case, typically no diff fro 1333 to 1800mhz

the video you see may be for 1st gen ryzen ddr4 paing with a very high end gpu

I forgot to mention, I have 4x4 mixed ddr3, 2 of them are Samsung memory at 1333 and the other 2 I got from a friend which are 1600mhz, but I know it will run at 1333 because it's the max my mobo supports
