Frametime and memory speed correlation?

[Gangstahfresh]

Okay so quick backstory:

For the last 2 months of my life this issue of microstutter has been consuming me. Dumped a ton of money on my rig only for it to microstutter every few seconds. This issue happens in all games that heavily depend on the CPU such as Fortnite,LOL, and CSGO. While the issue does not happen in games that depend on the GPU such as AC:Origins,farcry, tombraider etc... So that right there is what is really confusing. Naturally I thought my CPU was the issue so I went ahead and replaced my 4690k with a 4790k (shittest and most useless upgrade of my life) and the issue stayed so this made me conclude that the issue was not on my CPU's fault. So then I went through crazy amount of time diagnosing issues left and right and hell I even made a list of the stuff I have already tried and that did not work:

Went back to older Windows 10, 2016 LTSB 1607 version

turned off all 3rd applications and only kept monitoring program and game up *

did the whole windows 10 memory standby clearing (I really thought this was going to fix it) but sadly even when I clear memory standby and memory cache resets, the problem is still there so I doubt its a windows 10 issue * * *

disabled full screen optimizations *

turned gsync off/on *

tried uncap vs cap fps *

fullscreen vs windowed *

Hell I even started using vsync with the input delay and still no help. *

used ULMB mode,fast sync everything... *

Thought it was my monitor with its Gamemode and turned that off and nothing *

Turned off xbox game DVR *

played around with different refresh rate 120,144, overclocked to 165 hz and nothing worked. *

Turned windows into high performance and same issue.

Tried on another PC in the same house and same issue

Overclocked and stock speed my CPU and cache

So when I tried on another PC this made me think that hey the issue is probably not my hardware and its either power or internet because that's the only 2 things my 2 Pcs share. Its not the internet because when I unplugged the ethernet cable the microstutters were still there so then it must be power right? Nope I used my laptop and its not plugged to a power socket and same issue. So the fault has to be on these games and not me or am I crazy? I guess most people don't complain about microstutters and frametimes is because they don't spot it and so even though this issue is happening to everyone who plays on the CPU bound games, most don't even notice the stutter to even report it.

So I had a lot of freetime and decided to play around with my ram speeds and this was shocking, heres a frametime graph of around 10 mins for each graph while running Fortnite:

800 MHz ram speed: https://prnt.sc/lbladi

1600 (XMP) mhz ram speed: https://prnt.sc/lbl9z6

1800 mhz ram speed: https://prnt.sc/lblaab

So at speeds of 800 mhz the frametime spikes were at around 26-30 MS and at speeds of 1600-1800 they ranged from 16-20 MS, so i can't believe i am saying this because how the fuck could ram speed cause this but is it possible that the higher the ram speed is the less and less you will notice stutters? FOR CPU BOUND GAMES ONLY Again at ultra settings triple A graphics games i was not seeing this issue, but when i played these multiplayer games i started seeing it, idk it has to do with texture filtering or assets loading or something along those lines. But yea what are your guys's thoughts on this? Should i even bother buying 3000 MHz ddr4 ram compared to my 1600 ddr3 ram or is this a more serious issue and i should do more tests? if i should do more tests then please link em below. Thanks! Also any forums or subs suggestions to ask about this issue? I could just simply copy paste my issue so more people could see it and hopefully we can find a solution to this shit.

if you tried a whole new system and it still micro stutters... something is seriously wrong.. i am on a old laptop running csgo and i get stable 70fps.... my wild guess: viruses... try clean installing windows after a backup

Nah not virus

Considering time between spikes appears to be more or less the same, I'm more inclined to think there's something more fundamental going on and slower RAM just happens to exacerbate it.

You probably hit it on the spot, the problem is always there whether I have fast ram or slower ram, obviously faster ram seems to heal the problem by lowering the spikes from 30 something MS to sub 20 MS however its not curing the problem. I said that games like AC Origins don't have this, well guess I was wrong heres a frametime graph of Origins if you don't mind seeing:

I had an FPS cap of 60 on that game with freaking gsync enabled and yet every time my FPS hits 61,59,58 my frametime spikes to the 40s... I don't know what to do anymore, this is driving me nuts, any suggestions I am open.

Visible and record-able fps drops are not network related. I am just gonna give you a list of suggestions in no specific order.

-change priority in task manager

-change the power setting to max performance in nvidia control panel (in league, high end nvidia gpus are so heavily cpu bound that they have a tendency to switch to lower p-states, or even 2D clocks, causing severe stutters, I don't own or play the other games mentioned)

-try just two sticks of ram

-make sure your cpu isn't throttling in any way

-make sure your power delivery (vrm's) are not throttling in any way

-if youre still having issues and you have the tools and know how, make sure the electricity from your psu and wall are consistant (a non technical way to test would be try at a friend or family members house)

Actually great suggestions, haven't tried many of these, had some questions on some though.

 

- Not sure how to check my power delivery is not throttling I can send you graphs of say power% in afterburner or would that not show us what were looking for?

 

- Again not sure how to see if electricity from psu and wall are consistent - I could prob take my PC to a friends house and test there.

VRM throttling would usually result in a drastic power drop. If it is thermal, then more airflow over the VRM would likely fix the issue, if its raw power, you may have to tone down the OC on your CPU a bit, but since you said this happened at stock too, this one seems highly unlikely unless the VRM's on your board are hot garbage
