Re: Trying Hard for that Record SuperPi 1M run? Here are few tips.
Nice Info , It did help me learn something.
Shripad said:Generally its seen all over that though people share how to overclock, how to get stable overclocked system, I havent seen many overclockers sharing how to get those illusive record breaking runs at insane clock speeds out of their systems. And honestly most of them DO NOT want to share how they got it to bench at such speeds.
System stability is never a criteria here. All you need is a successful superpi run. Everything is fare here. All tricks in the book are fair as long as your processor finishes that run.
Here are few tips for fellow TEites who are looking for such tun.
Most of experienced overclockers will already know most and all of this. If you have anything to add, please do so.
I am not going to explain all those regular CPU - NB - VTT voltage stuff as I expect that whoever is going to try this already knows basics of overclocking. the 5th tip is most important one as many people never try this.
1. If you are having problem booting into windows with whatever CPU, NB, Memory voltage you are tying, play around with GTLREF voltage ratio. This seems to help in giving additional stability. Not all motherboards have this option in voltage settings.
But if yours does then try settings from 55-80%. There is no rocket science there. Good ratio varies from setup to setup.
2. If benching in windows, download royal noir theme and use it or simple Royal theme instead of windows basic or Standard windows. This theme for some reason uses least amount of system resources and thus less chance of system crash.
3. Run the benchmark multiple times. You will observe the time improves usually on 2nd run.
4. You can also try to end explorer.exe process from task manager after launching superpi and then do a bench run. Helps sometimes.
After run is complete you
restart explorer.exe from WIndows Task Manager Application Tab by clicking New Task button and typing explorer.exe in the space provided and hitting enter.
5. On multi core CPU usually one of the core is better than the other. SuperPi is not a multi threaded benchmark. It only needs 1 core.
If SuperPi run is failing then using task manager, Rightclick on the SuperPi process, click on Set Affinity and only select 1 CPU. Say CPU0. And see if your run completes. If it fails, then only select 2nd core by selecting CPU 1. And so on ( for quads ).
This gives you best chance of getting the best run on the stable core.
6. You can also Try setting the priority of Superpi to Realtime. I havent found it impacting the scores too much to be honest.
7. Try to lower your resolution to as low as possible. I personally dont bother with this as it hardly makes any difference at all.
8. Disable the onboard Sound and Lan from the bios.
9. Try to keep as less processes on startup as possible as many can crash the system at insane clock speeds.
10. Memory timings and Memory speed DO NOT matter much for SUperPi 1M run on todays large L2 Cache CPUs. So make sure your priority if to get max Mhz out of your CPU. You can sacrifice on the memory speed and timing.
Thats all for now. if i can think of anything else I will edit this post.
Feel free to share and I urge those OC gurus out there to share the knowledge with others.
