The game is hammering 4 of the 12 cores in my cpu while in time trial mode. Spikes all the way up and just heavy usage of those cores. They are running at 70 ish% Overall usage between all cores of cpu is 10-20% This is on a ryzen 9900x 12 core 24 threads Playing 90 fps in VR I have not tried ai or mp race lately, i hope they will use the other cores. If not i think it will be a problem. I don't remember it being this crazy on the cpu EDIT. I do have many of the graphics settings cranked up. I have not tested it on lower settings. Can you tell me what graphics settings are most demanding on the CPU?
I don't think this is much of an issue anymore and i think it is mainly meant for cpu that has one ccd with v-cache but please correct me and enlighten me if i am wrong.
As i suspected We tested Core Parking on the Ryzen 9 9900X and actually got worse performance - PC Guide Thanks for trying though
Interesting. I have a 5800X3D. I must say it's been an amazing chip. Was such a huge upgrade from the 3700X I had previously. From the article... "Core Parking is supposed to pseudo-deactivate the CPU cores that aren’t in use, reducing CPU power draw and allowing the cores that are active the headroom to boost higher. We can see how this makes sense for X3D chips, but not for the 9900X and 9950X"
hmm, this is interesting. SMT 'On' = crazy cpu usage graph spikes and uneven distribution of workload across the cores. SMT 'Off' = high smooth usage graph on top cores that evenly distributing the workload down to the rest of the cores with a obvious decline in usage the higher the core count. Seems we may have a problem with multithreading? Multi-core workload looks very nice but with threads enabled it turns into something not so nice
It doesn’t look like your cpu is boosting , unless this is some idle state . I had this problem up to a couple of weeks ago. I updated my bios and chipset and only made sure rebar and memory profile were enabled , and now get 4.2ish ghz. but I discovered this would get stuck at base 3.6. If I turned on some “enhancements” in bios . and wouldn’t correct itself unless I reset bios to default again .
Thanks. It was idle. I just had AMS2 open in the background, sitting in the pits. Last night I also installed all the AMD chipset drivers. Not sure if I had done that after installing the 5800X3D. I went back to balanced power option, which is now parking my cores. Rebar and memory profile are on. After reading Dmand's link I went down the rabbit hole, watching some video's on JayzTwoCents YouTube channel and some others, and decided to go back to normal parking. After running a few stages in EA WRC all looks good. No stutters, no issues. Edit: Just to be sure I reset my BIOS to default and turned on Rebar and selected my memory profile. BIOS was up to date for my board.
Things working much better now. Thanks for pointing out my CPU speed @Kuku. This is how it looks now, with core parking enabled. Parking seems to be working well with consistent spread of processes and speed is boosting.
oh did you reset your bios ? I literally ran stuck at 3.6ghz for about a year . don’t think it made a big difference to be honest.
Yeah, ran the AMD chipset driver install, reset BIOS to default, turned on Rebar and selected memory profile. Set Windows 11 performance profile to Balanced. It's been a year since I put this chip in and I had no idea, so you aren't alone.
