Benchmark Scores They're pretty good, nothing crazy.
it's hard to run 32gb at a very high speed on a dual channel board right now. 4 dimms of 8 will limit how far you can push the ram and 16gb high density dimms are slower by default, so 16gb faster > 32gb slower unless you need it for work.

I have never used up more than 10 GB of 16GB. Been running 16GB since December 2012. For gaming, its a matter of 8GB not being quite enough for all circumstances, and 16 being more than enough for all circumstances.

I have 16GB since 2014, I only see 24-64+ being for video editors

Ive noticed something regarding RAM usage that I dont fully understand. All 3 of my pcs have 4x4gb ram. My old Phenom Ii (1333Mhz) uses around 12GB Ram when launching FIfa 19. My i7(2400mhz) and Ryzen(2666Mhz) use less than 8GB. Not sure if its because of ram speed, chipset, or GFX memory. Ive started assuming that you need more RAM if its slower, but an actual explanation would be welcome.

That'd be strange, assuming you're using the exact same Windows version on each machine and that there is nothing running inmediately after startup.

Yeah the PC is 10 years old though. Even at idle on desktop it uses more RAM than my other two. All 3 of my PC's run the same settings, with everything possible disabled including background apps, and windows and microsoft store updates paused. In fact I was running 8Gb ram at first using matched Vengeance sticks. The RAM is mismatched currently but running in dual channel. In fact I only added the extra 8GB because FIfa was using all the available Ram and I thought adding some could help FPS. It didnt help; 35-40FPS is all such an old CPU can do. The only noticable improvement after adding ram was alt tabbing. Gaming performance seems to be limited by CPU already with 8GB only, which I confirmed with GTA V and BF1 which maxed the 8GB as well, used more than 10GB when 16GB present but FPS and general gameplay felt the same. I was actually quite surprised that the games dont stutter when all the RAM is being used. For reference I had only 4GB in my Q9400, and GTAV ran at 50FPS with lowest settings. Same GFX card too. Ive had this card (Asus R7 260x 1GB) since 2012 popped it in my i7 to make sure it wasnt the bottleneck, it held 60FPS at all 3 games on lowest settings. Im sure some Ram must be shared with the card, because GTA V shows 2300MB/1000MB yet the game runs smoothly.

Does the Phenom II system have a hard disk drive? Wonder if Windows disk caching might be responsible for the higher Ram usage.

Yeah it does. In fact its an old Seagate Momentus 640GB from a laptop. Could that be the cause of the excess RAM usage? The other PCs do have SSD's as boot drives.

Honestly it was just a lucky guess about hard disk drive. I thought I seen my parent's older HP Phenom II exhibiting the same behaviour, and they don't play any kind of games on it.

Ah I see. Well ill be gifting the PC to one of my best friends as a housewarming gift this weekend. His Xbox One is broken, and I told him not to buy another one , and that the PC would run FIFA so he should only spend when the next generation is out, so I'm gonna try trade the CPU and 2x4GB sticks for at least a FX6300. Should run Fifa 19 and 20 easily.

16GB is more than enough for 4K gaming at present
that will change in the future, but it hasnt happened yet.

Most games are designed and optimised for 8GB systems at 1080p, and the system ram usage doesnt jump up that much as the res goes up (unlike VRAM, which does)

Years ago DX9 games shadowed GPU ram into system RAM, but that was corrected with DX9 and slowed down the increase of RAM needed for gaming systems

Ive noticed something regarding RAM usage that I dont fully understand. All 3 of my pcs have 4x4gb ram. My old Phenom Ii (1333Mhz) uses around 12GB Ram when launching FIfa 19. My i7(2400mhz) and Ryzen(2666Mhz) use less than 8GB. Not sure if its because of ram speed, chipset, or GFX memory. Ive started assuming that you need more RAM if its slower, but an actual explanation would be welcome.
I typed my above comments before seeing your post, but its probably the level of DX support on the GPUs, making a guess that the newer systems also have the newer GPUs

If you can afford it it is time to get 32gb prices never been this low for many years. And I do have a feeling they will go up soon again pretty soon.

Running more than 2 sticks (assuming going from 2 x 8 to 4 x 8 from different packages) may put a damper on RAM speed, timings or even your CPU your OC.

As someone once said: "nobody will never need more than 128k of ram" (yea I know who said it :)) hahahaha
The quote is 640K and Gates said it's apocryphal.

Pick most any hardware specification and software bloat will exceed it at some point. Game developers learned much from Crysis marketing. The idea has been to get used as a benchmark by all the review sites by going further than other games in terms of hardware demands. Since there is a marketing incentive to push the limits of hardware one can rest assured that RAM bloat will be an issue, likely before the games become advanced enough to truly need all that RAM. Do an EA and claim that the game has special secret tech that is really really advanced (remember SimCity 5 having to be always-online because of all the super-duper calculations EA claimed were being done by its supercomputers?).

It wasn't very long ago when 8 GB of RAM was considered plenty for gaming. Prior to that it was 4 GB. It doesn't seem really so long ago that the 1.5 GB buffer of the normal GTX 580 seemed like plenty.

Gates understood that hardware is always advancing. The only people who should take that quotation seriously are those who don't realize that tech insiders are highly-familiar with the way hardware is always advancing. No software or hardware guru would ever claim a certain amount of RAM is enough for anyone going forward. Claiming it's enough for them at that point in time and in the near future is another matter.

I mostly agree, but 8GB has not been considered plenty for some time. In the Sandy Bridge era, 8 years ago, 16GB was the recommended amount. System ram needs haven't increased very much on an individual application basis, but in the time since, there are now a lot of peripheral apps now that are considered a must have for many in online gaming such as OBS, discord, etc.


In a gaming sense, in your example of bloated ram usage, often this applies more to VRAM, but hopefully the truly bloated games that are worth playing can be tweaked in their settings to reduce the bloat for lesser provisioned systems. Generally one can get by with a really minimal system for years by running lower settings, sometimes by modifying ini files. A lot of the demanding settings are actually very subtle visually, and gameplay does not suffer as a result of disabling them. However, you generally can't go wrong with getting a higher VRAM card if the option exists.

Right now, because ram is relatively cheap compared to the last 4 years, I'd probably go with a 32GB system if building a new machine, just to extend my system's useful life.

Thing is, 8GB of ram and that 1.5GB GPU can actually still run modern games just fine, if you're happy with 1080p at lower settings.

While we do get the hardware creep of needing new harwdare over the years, it seems like that creep is slowing down - year on year we may need 5% or 10% more RAM, but thanks to the nature of doubling in size, we get a hefty time gap in between

Right now 12GB of ram would easily be sufficient for gaming systems, but we cant get that with just two sticks of ram

Should run Fifa 19 and 20 easily.
I sold all 4 DDR3 1600Mhz sticks for a FX 8320 CPU. Popped in 3 random sticks of 1333Mhz totalling 8Gb. The PC is far slower when navigating Windows. Gaming FPS has improved in every title, and the PC can run FIFA 19 just like I promised. That said the lack of RAM is an issue, my PS4 controller randomly disconnects. (Ds4windows gets forgotten in the background) Thankfully he uses a wired XBox One controller which has no such issues. A far better idea would have been to have kept the matched 4GBx2 Vengeance(1866Mhz using manually set XMP timings) and paying a bit of cash for CPU, but i didnt want to spend money on a PC put together from obsolete/spare parts.

lack of ram wont cause programs to close in windows or wireless controllers to disconnect, everything is designed to prevent that

The PS4 controller or the bluetooth dongle is the problem there

Whearas i do agree somewhat, its specifically the program that stops working, the controller remains connected via bluetooth to windows, but stops being recognized by DS4windows, I have to alt tab to have it recognize the controller again. I suppose I could look into it, but it never happens on my other 2 PCs. Does it matter that "Background Apps" is off perhaps?

you've still got 1.2GB of ram free, being used as cache in that image - you aren't low on ram there.

Whatever the problem is, its got to be related to the controller itself (in your case, the software)

I see thanks, I will try and reinstall the software. I have changed a fair amount of hardware since it was installed. Either way Im the only only one with a PS4 controller, and I play FIFA on Keyboard so it shouldnt bother my friend.

Benchmark Scores Faster than yours... I'd bet on it. :)
Do you guys have a good guide recommendation for optimizing windows 10 to be more efficient?

I remember finding one in the past which listed the services which were safe to turn off and other tweaks as well
Don't. It's not worth it.

16GB is the sweetspot. It only becomes a bottleneck if you can use more than you have.

When you hit 2000+ tabs. 32gb fixed it for me.

You're fine. 16GB of system ram will be good for at least the next 3 years.

16GB is currently optimum standard for gaming. I can't imagine any scenario, except memory leak, where any game would hit 16GB of ram usage. There is plenty of games which utilize/allocate over 10GB of ram at 1920x1080 and higher resolutions but none actually hitting 16GB. I have some odd memory leak, i assume it is a memory leak, in rise of the tomb raider as this game can utilize on my pc with radeon r9 380 up to 14GB of ram. I assume it is a memory leak because when i tried the same game at the same settings at friend who owns 1080ti ram usage was under 10GB and that made me wonder wtf is going on.

Anyway, with 16GB of ram you are safe for next few years. If you are considering to go with more than 16GB then, purely for gaming, the only reasonable thing to do is to utilize extra ram as ramdisk where games work way better than from ssd. BTW, x570 is the first consumer chipset to support up to 128GB of ram and i would love to go with such amount of ram for ramdisk but that's too expensive to me at the moment.
