Using force_turbo=1 I was able to get to 1200. Two notes on that overclock: First, I could not push it any further with an over-voltage of 8 vs 6. Secondly, I could not get it to boot at anything above -30C. You may be able to use difluoroethane(air duster) to replicate this as it has a boiling point of -25C(have good ventilation and find cans that don't have a bitterant).hojnikb wrote:How far can you push it on 1.4V voltage ?
Duh! Why didn't I think of that?!? Thanks for the idea!dom wrote:I know the 1.8V supply runs pretty close to the core voltage (the 1.2V-1.4V supply), and James Adams had a pretty neat mod to run the core voltage off the 1.8V supply...
Great find. I haven't had the time to collect as much data as I would like to. The guy in your link did a great job. It looks like his data is in line with yours. He was able to boot at 1166, but was only able to get it stable at 1100. I wonder if I could create a script to automatically bench and collect data as it is so time consuming to do manually. Something with privileges that could automatically tweak values and reboot... Just thinking out loud. Thanks for the clocks as well. I'll have to figure out an elegant way to collect and display data, maybe a box-plot with successful clocks vs voltage.SteveRPi wrote:This person documents overclocking Ppi2 to 1200 MHz using a standard set-up:

My RP2 is stable at 1100 MHz, using a standard 1A(? I think) power supply, no force-turbo required:
Temperature: 44.9 C
Voltage: 1.39 V (+0.19 overvolt)
Min speed: 600 MHz
Max speed: 1100 MHz
Current speed: 1100 MHz
Using the same instructions, I have managed to boot to 1166 MHz, but it is less stable.
PS: apologies for repetition from another thread.
Record or aquire a demo/replay file for it and then open the console (~) and type:Last thought before I run off to bed. Does anyone know how to get OpenArena working as a benchmarking platform? There are a lot of guides out there but they seem to be dated and don't work anymore. OpenArena still works, but I can't get it to count FPS and total frames rendered.
