CPU and GPU underutilized...

[ExalyThor]

Hi! I have a 2600k - 980ti system. But I have a problem... The cpu sits at 60% utilization and gpu at 80% utilization in most of the games that i play...(far cry 5, dying light, 7 days to die etc) the cpu is overclocked to 4.6ghz and the gpu to 1500mhz core/2000mhz mem. Ram isn't a bottleneck either - 16gb 1600mhz 8-8-8-24 (frequency isnt high but latency is very good).

Don't need to be at 100% TOTAL CPU usage to have the IPC bottleneck show.

 

It's case and point being 1-2 or 1-4 threaded titles,.. only two cores being fully tapped isn't going to max your CPU usage, even if the Windows scheduler can mitigate some, spreading those 2-4thread loads across all cores and threads more,..it can't cure a game engine threading/optimization 'issue' when those games are not 8-thread aware, and Singlecore IPC is good when the 4-6thread games can unleash it a bit better but not great for the needs of the game in question in those situations,..

 

Not all games are multicore aware beyond 2-4 threads (many exceptions but it's not universal)

The weird thing is, far cry 5 and dying light do scale with 8 threads, and they even had big gains from going from 4 to 8 threads. (20% for DL and 30% for FC5)

they might benefit from more cores, but doesn't mean that they treat all cores equally, most likely there's a few cores that are pegged at 100% while the other ones are at 30-40% for example, and because of that you get a total CPU usage that isn't 100%

You can possibly bring up minFPS values and cure some GPU usage drops a bit if your successful in Memory overclocking (or have the options to) for 1866Mhz/2000/2133Mhz at slightly worse timings,. it couldn't hurt to try anyway. (Few hours or less should cover finding out)

It'll be a bit of testing with stability with apps,..chasing higher memory bandwidth vs similar or looser timings vs faster speeds you want to attain.
The latency is still good when loose because your already low with 1600Mhz at CL8.
Read guides/Watch Videos.

Important.Link both Sticks using your OC menu area.

Try for 1866Mhz at Auto timings or or slight manual values to the first 4 options,..then +1.test

Stock,..iE 2T 8.8.8 auto everything else should work similar to how you have it now.

2T 9.9.9 or 2T 9.10.9, 2T 10.11.10 and such...read what other sticks of (speeds you want) and their CL values and voltage. (it'll vary a bit, but combinations exist that many can share)

1.5v or 1.65v some kits can do 1866 on both, try 1.5v first, if not try 1.65v and see if you can keep chasing 2000/2133.

I recently got 1866Mhz to 2200Mhz on a decent board with ample options.

Still weird considering its only a 4 core with ht enabled, not some crazy 6 or 8 core..

Not really weird.. not all games utilize hyperthreading

Its a 4 stick config, and i couldnt hit 1866 at 8-8-8-24 with other timings on auto even at 1.8v. Tried to train the mobo for like 6-8 times before giving up. Also sandy bridge is limited at 2133.

Sandy can OC Ram beyond Rated 2133Mhz speeds, as most processors can today. Depends on Board and OC methods.
4 sticks can introduce errors compared to 2, mostly in Phenom2 and prior timelines,.. trying for 1866Mhz with TIGHT timings won't cut it.

1600Mhz can come in CL9 as standard and CL8 you have is already tight, and 1866 aint happening.

1866Mhz at CL10.11.10 (try 1.5v before 1.65v) is likely to boot and work,  and you can expand from there.

CL11.11.11 and 1866/2000, it's not a fast process.
CL-8 looks good, is fast, but 1600Mhz frequency is a bottleneck on your machine (chasing higher hertz FPS almost (Good GPU) with Higher CPU loads the faster ram makes way more sense, i'd put money on it (if I was chasing it myself) I'm that confident)

Don't think CL-LOW is everything.

No, sandy is rated for 1333. It litterarly hits a brick wall above 2133. I might try higher frequencies at looser timings though.

Sandy will do 16GB of G-Skill SniperZ 2400Mhz Ram CL10.11.11, I ran with it for 5 years at those speeds.
I did have an expensive board but facts are facts.

 

I have little doubt you couldn't get 1866Mhz/More out of CL10-11 or a Hybrid 11/12.
