September 9, 201411 yr First core ~100% is okay, however, the other cores at zero is odd. P3D is multi-threaded, maybe there's room for improvement, but the other cores should be at least at ~20-30% in flight. If not I'd check if there's an Affinity setting or some external program/tool hindering P3D to use the remaining cores (check and maybe try to reset in Task Manager). Kind regards, Michael Thank you for your reply! I was being a bit dramatic I'm afraid.. the other cores are indeed between 25/30%. Does it matter though that CPU 1 is in a way 'over 100%'? What I mean by that is that instead of the top load being around 99/100% (with a spike), the load is flatout 100% .. which makes me assume that it wants much more. EDIT1: Well I just answered my own question! I overclocked my pc to 4GHz, which has the effect that the CPU count on core 1 never approaches 100%, but sticks around 95% at it tops at most. Which is good, except for the fact that this really means my GPU is bottlenecking me.. (HD 6950).. overclocking GPU here I come! "If flying was the language of man, then soaring would be it's poetry"
September 9, 201411 yr You can lower the first core from 100% quite easily with the known trick to (i) uncheck the first core in Task Manager, (ii) check it again. This gives me a quite even load distribution overs cores. However, one of the LM developers (Zach Heylmun) advised against this as it damages P3D interal thread management.

This make each core independent how it will be throttled. Spirit
September 9, 201411 yr I don't know if "per core" OC is possible with your MoBo. This make each core independent how it will be throttled. Spirit I actually have the Asus P8Z68-V/GEN3 motherboard with the 2500k so I have pretty much all the OC possibilities I want, including individual core clocking. However, I have never read anyone actually saying that it is better to do that instead of balanced OC'ing.. Do you have any experience with it?

September 9, 201411 yr However, I have never read anyone actually saying that it is better to do that instead of balanced OC'ing.. Do you have any experience with it? Well, just had it done and the temperature is a bit more moderate with "per core" OC. Now I'm back to balanced OC because of checking some AM settings. But I'm only playing around a bit with latency monitoring etc. I may go back to "per core" because of our climate here in Thailand. Spirit

Playing with the affinity mask is not advised anymore. And I myself always get problems with texture loading if I do not let P3D use all cores (as 2.3 does by default now). OC'ing per core seems a but useless and it's not what pmb or lrcghost were talking about so I don't know where that came from...? because of our climate here in Thailand. Totally OT but I can imagine the climate over there may force you to take a different approach on IC'ing: I just been to Thailand for a week and it was hot indeed. ^_^

September 9, 201411 yr OC'ing per core seems a but useless and it's not what pmb or lrcghost were talking about so I don't know where that came from...? Sure you know this? Your MoBo may have this feature too. If one don't try - one will never know, remember? Spirit
September 9, 201411 yr Sure you know this? Your MoBo may have this feature too. If one don't try - one will never know, remember? Spirit My mobo has that feature, yes, but I don't understand what the benefit of it should be...? Right now all my cores run at 4.5 Ghz on my PC using the 'All cores' option in the BIOS, so why would I want to seperately OC them to 4.5 or set one to 4.5 and another tp 3.5 or something like that...?

Hi Jeroen, well, you didn't understand that's true. Understanding things is essential for improving or changing processes. If you run your CPU permanently on full speed then it's indeed useless to OC 'per core". But I guess that you run your CPU dynamically so it will be throttled when idle and the speed will raise depending on the load. If you do now OC "per core" then each core will be throttled or accelerated upon the load separately. This helps me to reduce the temperature significant. Give it a try because it doesn't hurt but then you may see the difference and understand the benefit of doing so. Spirit
September 10, 201411 yr Ah, ok, I understand, thanks. But well, actually my CPU is running permanently on full speed. Heat is no problem at all and I don't like the cores to be throttled: I want to be sure I get all they can give all the time! ^_^ So I do understand the benefit now, and I also see it's of no use to me.

Hi Jeroen, of course, at your country heat shouldn't be a problem and I wouldn't throttle my CPU either. Spirit
