okay so why will a 32 gig system get more fps than a 16 gig system even tho the game isnt using all 16 gigs?

No, as long as your capacity is not maxed you will gain NOTHING from adding more RAM.

Current Specs:

CPU: AMD Ryzen 5 5600X - Motherboard: ASUS ROG Strix B550-E - GPU: PNY RTX 3080 XLR8 Epic-X - RAM: 4x8GB (32GB) G.Skill TridentZ RGB 3600MHz CL16 - PSU: Corsair RMx (2018) 850W - Storage: 500 GB Corsair MP600 (Boot) + 2 TB Sabrent Rocket Q (Storage) - Cooling: EK, HW Labs & Alphacool custom loop - Case: Lian-Li PC O11 Dynamic - Fans: 6x Noctua NF-A12x25 chromax - AMP/DAC: FiiO K5 Pro - OS: Windows 11 preview - Monitor: ASUS ROG Swift PG35VQ - Mouse: Logitech G Pro + Powerplay - Keyboard: Logitech G915 TKL - Headphones: Beyerdynamic Amiron Home - Microphone: Antlion ModMic

Well for 1, the first one is 1x8 so he's not making use of dual-channel.

 

For the jump from 2x8 to 2x16 I would assume it has to do with the 16GB sticks being dual-rank.

I have 32GB of RAM, and I got it because I run a huge amount of tabs and programs while gaming. All that the extra ram does if you are purely gaming is improve the 1 and 0.1% lows, and even that is a small improvement

Ok i might have exaggerated a bit by saying "nothing".

 

I've seen several reviews from reputable sources, such as HardwareUnboxed and JayzTwoCents at show, most of the time the difference is marginal (if not in margin of error).

If you're saying 2-3 fps or whatever is different enought go buy a 32 GB kit.

The dude in the video has no explaination as how he is doing his testing.

you will see a jump from 1 stick to 2 because then you have dual channel.

When you already have 2 sticks there wont be a difference.

I looked at the youtube page and I didn't see anything about the CL ratings of the memory.   CL ratings will play a role in how quickly memory responds.  We also don't know how he tuned each set of memory in the BIOS - just used XMP for all tests or did his own overclocking to the system to use 3200 MHZ ram.

 

The video in question leaves too many variables unexplained for me.   If you can find more information about how each test was run, that would help.   I also found it weird that the memory usage was different.  The 32GB tests always show a higher usage of memory over the 16gb but neither are using enough of the memory to really explain why that would be.

All else equal, there is a performance gain moving from 2 ranks to 4, although smaller than moving from single channel to dual channel. I would be interested to see how 4x4 GB does.

Windows will just decide to use more ram instead of using the sawpfile if it sees you have it.

I understand that, but the game is using barely half of the 16gb and a fourth of the 32gb.   Just seems wierd to me is all.   It is consistently larger across the games in the video I reviewed.   We don't know what all was running on the PC that could cause the jump in memory and affect the FPS.  

 

I prefer reviews where they show the exact configuration of the PC, Memory including timings, etc...   I am not saying this video is wrong.  I just don't have enough information to make a conclusion.

One possible explanation could be that the game scales it's use of memory based on how much memory is available overall. If more memory is available, it'll use more of it as a cache, which could improve performance a little bit as you have to reload data from disk less often.

 

However there's quite a bit of variance in the frame rate and e.g. in Assassin's Creed you can see the 32 GB system sometimes dips below the frame rate of the 16 GB system. To reduce the variance caused by background programs running in parallel, I'd really like to see a result where each test is repeated multiple times and results are averaged to minimize the margin of error.

it will on some games but not just because it has more to use it helps that everything else running in the back ground now has enough ram to use so it not choked by not having ram i just went from 16gb to 32gb the other day because i saw warezone using 13.5gb of my 16gb so that left 2.5gb to run windows and what ever else yes there is virtual ram but that is being used off a hard drive or ssd and not as fast as having more ram
