ARMORED CORE PSP RETROPIE PC
I am well versed in standard pc manufacturing but I have not really delved into arm architecture aside the occasional whitepaper but I am assuming we have something very similar going on with the arm chips on the pi's. And those higher level instabilities are managed with cooling the more you ask the more you have to cool. Which is where all the overclocking stuff comes from your increasing voltage to a chip and providing above standard cooling which will bring it up in speed at the risk of unstablizing it. Meaning the I7 processor you buy at 2.80 Ghz for 100 dollars more the the 2.4 ghz proc could have come from the exact same wafer that the less expensive one came from one can just handle higher voltage at the same level of cooling while staying under a certain error rate. This is just something from the world of physics and properties of silicate that happens. Then what they do is apply steps of voltage to them and run burn-ins on them as they increase the voltage certain chips from the same wafers will begin to have errors at that voltage where as other chips will not. Say you were building a Pentium processor it is one big wafer that is manufactured then cut into pieces like a brownie. The instructions are built ad etched etc etc. When chips are made they are all cast on a single wafer. When I talk about different behavior I am talking about the dynamic of different properties of silicon even silicon from the same chip. J-Tek Acrylic case (It is well ventilated) Aluminum heatsinks that have been thermal epoxied on, And an active case fan that is oriented to blow cool air over the heatsinks and away from the chip. A Pi 3 by default will throttle cpu_down at 85C I set my config file 5 degrees under thatwith temp_limit=80 just to be more conservative because I am using an aggressive overclock.Īll of my Pi 3 setups are identical. Have U a heatsink AND fan? Is Pi in a closed case? Ceramic do not believe heat to be the issue.
the more you OC then the more likely this happens. the Pi3 thermally throttles once CPU hits 80C. I am actually going to try some Immersion cooling on one of my pis in mineral oil, but not enough overclocking experts have pushed their pi's so Im lost on voltage settings I need to get to 1600 MHZ but im sure we will get there soon. I have yet to test all the permutations of messing with these variables are but I am getting promising results thus I have had about 5 diff pi'(3)s underneath my fingers and have had the ability to test them against each other. Ppsspp_unsafe_func_replacements = "enabled" Ppsspp_gpu_hardware_transform = "enabled" Ppsspp_texture_anisotropic_filtering = "off" If the options are already there just edit them to reflect what I have below. Go ahead and add the following to the bottom of your /opt/retropie/configs/all/ retroarch-core-options.cfg I am actually going to try some Immersion cooling on one of my pis in mineral oil, but not enough overclocking experts have pushed their pi's so Im lost on voltage settings I need to get to 1600 MHZ but im sure we will get there back at it again with some emulator improvement settings.
As I continue to work on game optimization I will let you know if I find anything that brings it up to a better performance.
Just don't drive yourself crazy chasing something that the hardware can't perform and believe me I push every bit of performance out of the 3 that I can get. Only things that are going to push that game up is more video processing power. For example 1 or 2 that would not take the 1400 overclock.ġ pi that when using the same sd card played Star Wars Shadow of the Empire terribly but switching to others it worked fine.īut Birth by Sleep, even on my pi that I consider to be my most rock solid still has some slowdown. I have had about 5 diff pi'(3)s underneath my fingers and have had the ability to test them against each other.
