does ram throttle?

[Snowarch]

in minecraft, seus shaders gets double the frames(50-60) bsl shaders gets(25-ish) on same high settings. i noticed bsl fills more of the ram, so could it cause a throttle? my cpu isn't at 100% usage consistantly on even 1 core, so i know thats not an issue, and both use full graphics card, so that leaves ram. 

 

is it a throttle?

RAM doesn't throttle based on how full it is, but using more RAM means there's more of it to read/write which might cause memory throughput to become more of a bottleneck. So in the end it comes down to how these shaders work. Apparently one of them does more than the other which requires more performance.

 

If they're both doing the exact same thing, then it would appear that bsl is less efficient at it than seus. But it's also quite possible bsl is simply doing more than seus (e.g. more details) which might explain why it also uses more resources.

okay probably bsl is more detailed.

my ram speed is 3000mhz, so will adding more ram help with my fps at all?

If throughput is the issue, you'd need faster RAM, not more of it. As long as everything fits into RAM and your PC isn't swapping more of it isn't going to help.

 

However, it's not that trivial to determine whether your performance is actually limited by RAM throughput or some other component (GPU/CPU). It's also not a given that an upgrade would improve performance linearly (i.e. 50% faster RAM doesn't mean 50% more performance).

 

If your CPU and/or GPU are already at ~100%⁽¹⁾, faster RAM isn't going to do much. If your CPU is at ~100% and your GPU isn't, then it's possible your CPU is the bottleneck. If your GPU is at ~100% and your CPU isn't, then a faster GPU might help. If both are underperforming then memory speed might be the cause. You could try to verify that by increasing/decreasing memory speed. If that changes performance accordingly, faster memory could help (up to the point where something else becomes the limiting factor).

 

1) Take this number with a grain of salt. It'll be hard to optimize your system so that everything is running at 100% at all times. I'd say if usage is fluctuating between 80-100% you're probably not looking at a (significant) bottleneck. Whether an upgrade is a worthwhile investment or e.g. lowering settings is the better solution is up to you.

 cpu cant even get 100% usage on a single core.(since im on linux, we get usage by thread % percent, not a single percent like windows) so hard to guess. i assume less than 60% cpu usage since not even one of the 12 threads gets 100. 8086k at 4-4.3 ghz depending on boost.

 

3600 mhz is the fastest speed that isnt overclock on ram in general. my ram is rated 3000mhz with xmp, so speed isn't an option.

 

and my gpu is a 1060 6gb essentually. 

 

ill (possibly) have a 1070 soon. my 1060 gets 30 fps on high bsl 4k shaders, and 25-30 on 1080p but way more stable. so, likely my gpu. 

 

but will a 1070 even help with bsl shaders? my 1060's memory isn't fully used of the 6gb. the 1070 is faster right or just 8gb memory?
