Nice FPS increase going from Ryzen 1600 to 5600

[FT]

Using the same settings and same areas/time/direction-facing; I seem to have gotten a 25-50% FPS increase in the Skyscraper (I think #3), and roughly a 2X zed-increase at the same FPS in a small tester map.
Previously it took 50zeds to drop me down to 50-60fps, but I just spawned 100 with the new 5600 (non-G) and FPS stayed right around 60...only occasionally dipping to 58.


Next I'm going to see if adding another 2x8gb of RAM will do anything.
In some situations/games Ryzen (and Intel) can get a nice performance boost from dual-rank memory (I might not be using the right word there). Not to be confused with Dual-Channel (where there's 2 or more matched sticks), Dual-Rank has something to do with the RAM being able to interleave which normally either required sticks with chips on BOTH sides of the PCB (usually only found in certain models OR mostly in high-capacity 16gb+ sticks) or it may also be accomplished by using all 4 memory slots...unless I'm misunderstanding the HardwareUnboxed video about it from over a year ago.


Sidenote, I remember AMD making a big fuss about how difficult it would be to add support for 4th-gen Ryzen (aka, fulfilling their earlier promise to support it) on older boards with smaller bios memory. Some of the threats included dumbing-down the bios options and/or losing support for older CPUs and most/all APUs to "make room".
Because of this, I was worried about updating my cheap DS3H V1 board and potentially losing options or CPU support (it does have a small bios memory...it's old).
Turns out the newest bios update is still relatively tiny AND jam-packed with tons of new options along with all of the old ones. It also still worked fine with the 1600 and didn't have any listed incompatibilities.
I'm guessing some boards with really overly dressed-up bios GUIs may still have an issue with memory/space, but it looks like that doesn't HAVE to be the case.
Neat.

So, I'm not sure you grasped the whole picture on Single Rank and Dual Rank memory. Here is a link that explains it pretty well.
https://www.cgdirector.com/single-rank-vs-dual-rank-ram/

Note, they also tell of some situations where single rank can be better--mainly in OC'ing. In general, Dual rank will give the system more memory bandwidth.....which is a good thing. More 'bandwidth' when it comes to communications is always better. Also, almost all RAM sticks of 16 GB or larger is usually Dual rank. It's the smaller and / or older DDR that did / still uses Single Rank. Back in the old days, some motherboards wouldn't work correctly if they didn't have Single Rank Ram. But, I'm pretty sure mobo manufactures don't make that mistake anymore?....at least, I haven't experienced the issue in a long time building pc's.

But, I don't like all weather in all game in the world, so when I can do it like with 7DTD & in single play of course, I use dev command to desactive all weather (mostly the wind where it moves grass/tree).

And, that maybe making the difference. If you're modifying the game, like disabling weather, you can get a performance boost. Besides that, the Intel I5 you're using is a great gaming cpu vs multi-threaded AMD cpu's with extra virtual cores. A cpu with ONLY physical (actual) cores will outperform a cpu using both physical and virtual cores......IF they are close in comparison in most other ways.....In games I mean ofc.

So far it looks like adding another 2x8gb of RAM (so 4x8 total) hasn't changed performance in this game for me.


Does anyone know how to check if the system is using the RAM in dual-ranked configuration?
It sounds like 4 sticks basically guarantees it'll be dual-ranked, but I don't see a way in bios to tell whether or not all the sticks are running at the same timings or if they're trying to run at two different timings and maybe that (or something else) is forcing the system to treat the RAM as single-rank.

i got the fps increase mod and that helped a lot

@FT..... Unfortunately, there isn't anything that will tell you how the system is handling your RAM other than to display it's 'reported' timings and if it's in single or dual channel mode. The bios (when in advanced mode) should have a place where you can check timings / settings for each slot on the board. So, you'd see whether or not all the sticks are running with the same timings. Normally, the bios would downgrade all the RAM sticks to whatever the timings are of the slowest RAM module. If your RAM sticks are double sided....meaning there's memory chips on both sides of the RAM stick......then they are 'dual rank' and since you have all four slots filled, it is running in dual channel mode. There's almost no reason it wouldn't be.......aside from some badly mismatched ram modules maybe. However, most mobo's will throw beep codes if RAM is badly mismatched. So, yes....it should be 'interleaved' running dual rank (if both sides of stick) and in dual channel mode.

[FT]

That sounds promising. These are all Hynix AFR cl16 8gb sticks...just the first pair are 3000mhz XMP with slightly tighter secondary/tertiary timings while the newer pair is 3200mhz XMP with slightly looser s/t timings.
There are 2-3 different places in the bios where you can manually tune the RAM (a little redundant) but all of them seem to just show a single row of timings at least for the manual/editing part (the main section shows a pair of non-edited rows but I think one is just to check against). Setting the XMP appears to roughly split the difference between a couple of their timings instead of jumping to the lowest of the two options, which is kinda interesting (I, too, figured it'd just grab the slowest options).
Sorry to go so far off-topic on a RAM rabbit-hole.

Pfft - I have an RTX 3080, 64gb ram. i9. SSD and can barely get 20fps near or in city with medium settings. might have gotten lucky with the amd

Get the 'windows fix' mod on Nexus then. It should help in your situation. There's 2 versions. The first is the better choice for looks, the 2nd is if you have a potato pc and need every ounce of performance. You may need to check some things on your system. A system that beefy should be having no issue running 7d2d. I have about half that system and can run a steady 60 fps throughout the game on 'Medium' preset--slightly modified....reflections off, shadows medium. That's with Dynamic Mesh, Dynamic Music, and Occlusion disabled.....but, Occlusion enabled maybe better--still have to test with it.

2X8gb and only taking about 60 fps?? Are you just trying flex or dont know about pc optimization? Also do you know this game has severe perfomance issues?

Did you think something about 2X8gb would push most games well over 60fps? What made you think that?

Adding 2 sticks of matching (or near matching) RAM to ensure dual-rank functionality can add 5-10% performance to many games 1%/0.1% lows in non-gpu bound situations (where 7Days tends to have most of its FPS issues).


Not sure how anything I've said here could be considered a "flex" with how cheap and easy it is to add DDR4 (or a 5600) to an AM4 system right now.


I recognize the game is actively receiving optimizations as updates happen, along with the farther ahead hope of more optimization after content-lock. There are currently quite a few areas where the game's performance should probably be improved.
Why? What about it?
