Hmm dabei ist tasker so bequem :-D
Kann jetzt nur von mir ausgehen , wie gesagt Fancy_r32 mit per Trickster dezent runtergetrimmt auf gerade knapp über ein GHz , Display-Einstellungen im Trickster auch die fast niedrigsten Werte genommen uuund in den normalen Device-Einstellungen die Display-Helligkeit auch auf ca 1/3 gesetzt , sodas man gerademal nicht mit den Augen kneistern muss um noch etwas erkennen zu können.^^Kann ich gar nicht glauben das ihr nur so wenig Akku verbracht.
Oooha-Doch ist schon so einiges was da installiert ist - mom ca 117Habt ihr nichts drauf auf dem Handy?![]()
Hi,
I have optimized the device's LPDDR RAM timings. I was able to increase the throughput by ~10 %, in my opinion a fairly good improvement for the fact that no overclocking is happening. Here are benchmarks (performed with RgBandwidth RAM misc benchmark; threads: 1. 20 benchmark instances each, best result wins):
Why I want you to test this has the following reasons:Code:Stock Tweaked Copy 1249.9 MB/s -> 1373.0 MB/s --> 9.86 % improvement Scale 1084.8 MB/s -> 1188.1 MB/s --> 9.52 % improvement Add 938.4 MB/s -> 1050.2 MB/s --> 11.91 % improvement Triad 923.0 MB/s -> 1043.5 MB/s --> 13.06 % improvement
1) Lower RAM timings can cause system instability. As chips are all different, it may be working just fine for most users, but might as well not work for others. I want to find reasonable values that increase performance on the one hand, but are also stable on the other hand.
2) I'm not sure if this is actually true, but there might be a slight chance that more aggressive RAM timing eat some battery. I personally think this should not be the case, but we will see.
So what have I changed? People who have tweaked their computer's RAM timings might find some of the variables familiar. I changed the RAM timings from
toCode:tCL = 6 tRPab = 21 tRCD = 18 tWR = 15 tRAS = 42
The test version is here: http://boypetersen.de/fancykernel/tst/fancy_kernel-tuna-4.2-r32-tst01-ext.zipCode:tCL = 5 tRPab = 14 tRCD = 14 tWR = 10 tRAS = 30
