    I believe it was after a SetCPU update (2.0.3) when I noticed underclocking to 125MHz was no longer optional. Instead, the lowest setting currently available is 250MHz. I'm using Chevy's 1.2ULV kernel. Any help getting it back to 125? MHz

    the setcpu version I downloaded this morning is 2.0.3 and has autodetect.

    I dont see a feature to autodetect.

    My lowest setting is 250 as well.

    ok i just downloaded the kernel, the 7 slots are : 250/400/550/800/1000/1100/1200
    so 125 just isnt a slot on this kernel

    hmm ok thank you.

    i was using the 1.25 for a while but changed a few days ago once restarts became somewhat frequent. i must have overlooked the absence of the 125 slot.

    any idea what other chevy kernels have a 125 slot?

    all of his kernels are titled as 7 slot, but which uses 125?

    I may be wrong; however, I'm pretty sure 125MHz was dropped a while ago.

    Some phones don't like the 125 lower slot. They would be hard to wake up. I run a P3Droid kernel that has a 125 and my phone does well on it. YMMV!!

    Droid (1) stock FRG22D rooted and overclocked.

    P3Droid has Kernels with low voltage and standard voltage which featured 7 slot starting at 125mhz and 250mhz. I tried both low voltage kernels and worked just fine. I use SetCPU to autodetect and to govern the CPU. I don't have the "set on boot" checked. Reason for that is if the phone has issue with the kernel setting, it's tough trying to get to setCPU before it freezes. (I experienced this with 2.1 only) You just have to hit the widget to open SetCPU and the governing begins. I have it set to "ondemand" with the 1ghz kernel. CPU jumps to 1ghz when it needs to and then sets back to 125 or 250 depending on kernel. However, I have switched to Chevyno1 Kernel. P3Droid kernel as of a couple of days ago was not allowing SetCPU or TempMonitor to read the OMAP3 temperature (CPU Temp). Chevyno1 I am using is a 7 slot which starts at 250mhz and goes to 1000mhz. It allows CPU temp monitoring. Both Kernels worked fine, otherwise. P3Droid Kernel at 125mhz low voltage did not give me any problems. From what I have read is that the FRG22D "handles wake ups better with the low mhz settngs. I set these Kernels to run at (125)250-550 when charging or sleeping and (125)250-1000 when the phone is awake and not charging. Battery time has not been a real issue.

    thanks for the information. did you notice any battery improvement with the p3 125mhz vs. the chevy 250mhz? I used to run a similar profile to yours before 125mhz was dropped.

    my setcpu profile consisted of a 100% priority for screen off 125/125 to improve battery life. do you think the ULV chevy 250mhz kernel uses less power than a p3 LV 125mhz in terms of standby?

    I didn't play with both kernels enough to comment how long the battery lasts. Temperature of the CPU was very important to me. So is the battery. When setting SetCPU overheating monitoring should have priorities.... all the others should follow. I will try ULV kernel in a day or so.
