I am currently running 1.25Ghz[LV] Fascinate w/voodoo on my fascinate but i wanna make sure if my Set CPU is working correctly, as we speak my device is running 1250 max and 100 min on conservative with set on boot. I am not able to research much since i am at the hospital, thanks

did you just flash the 1250 lv? If so I would stress test it and then try and run some apps first before setting on boot.
If you've been running it with no problems than conservative with set on boot should be fine

As aforementioned those are the proper setting and you should be good to go if you havent had a problem yet. Im sure you auto detected to get the speed and slide the sliders. I would tell you to make sure you don't check the set on boot box yet. Many SF's cannot run the 1250LV stably, I cant. So to avoid a vicious boot loop dont set it yet. This does mean each and every reboot you will have to manually reset the speed but that takes a few seconds.
Im most curious by your hospital comment. I suppose at the hospital is different from in the hospital. I can just see it now..."Doc can we hold off on that surgery for a little while longer I just flashed a new kernel and need to run some Linpack and Quadrant."
Thats funny, i was diagnosed with colon cancer and i am trying to keep myself busy with the openness of android. by the way how do you Auto detect, my friend was kind enough to help me with flashing the kernel. you are the best Saps. At the bottom of the screen of the set CPU it says set cpu 2.0.3 autodetectAs aforementioned those are the proper setting and you should be good to go if you havent had a problem yet.

sorry to hear about your illness, but wish you a speedy and successful recovery!
as for auto-detect just click the menu-button on the phone (when in setcpu) and device selection, then autodetect speeds.

Wow, I certainly wasnt trying to make light of that circumstance. My thoughts and prayers are with you there. I just had a family member go thru that same battle.
By all means if this forum can offer you any distraction that is a good thing.
To address your questions, from the main secreen of SetCPU, hit the Menu button and then Device Selection. Scroll down and press Autodetect Speeds. Hit OK. You then will have to slide the sliders to the max 1250 in your case.
Be aware if you have not previously done this you are not at 1250. You can check this under scaling conservative it should show 1250 max, if it says 800 max you didnt autodetect and slide the sliders. Further some people like me freeze upon setting to 1250. So if you dont have another kernel on your phone you might not wanna do this from the hospital till you have a second one available. Or could do it and if you lock up just pull the battery. When you re-boot as long as you dont check the set on boot box the kernels boot at 800Mhz and you will be fine there

Then it is set right, I believe.

hope saps doesnt mind me grabbing this one
just click the setcpu widget and drag the slider all the way to the right on max, thats it

The Voodoo Toggle (free one) app did the trick. I'm now rolling in full form again, FINALLY! Custom wallpapers are working. I'm still polishing the one I'm working on. Mr Armageddon sent me an actual MP4 of the video file to pull my frames from. It will be a lot better quality now.
I'm going to test the SV 1200 kernal for a few days. If it works, I'll give the LV version another try. Like some of you mentioned, the LV 1100 was lackluster at best. Quadrant scores where in line with what you'd expect, and stability was there, but battery life sucked for some reason I can't explain.
Oh, and the widget shouldn't affect your battery life too much, but it's easy to remove and replace later if you want to be sure. Having less widgets and less home screens total certainly won't HURT your battery life!! Make sure you've got your screen all the way to the dimmest setting. Should still be plenty bright indoors, and it will sip battery for you.

SetCPU widget has little drain but honestly I would not use it just set it and forget it. As Battery Life King GoBruins shows us the 1000LV is an undervolted kernel and as such gets ridiculous battery life. Now I wont promise you nearly 4 days but certainly a lot more than stock. If you can get that one on there you wanna use it for max battery life. In fact what you can even do if you are obsessed with battery life is put the low voltage kernel on there and then run it at 800Mhz. There's a lot of tricks to maxing out battery life.

ok, how much voltage difference between 1250LV and 1000LV
i thought all the LV's ran teh same voltage

No but Im not going to debate Dirrk on his use of the term LV
His four DO2 kernels are as follows:
1Ghz=1225mv
1.1Ghz=1225mv
1.2Ghz=1250mv
1.25Ghz=1275mv
His 2 SV run stock 1300mv

I'm back to the LV 1100 kernal. It didn't give me the best battery life, even quite as good as the SV 1200, for some odd reason, but so far it's been the most stable on my phone. I got 5-6 lockups while testing the LV 1200, 2 while testing the SV 1200, and so far ZERO while testing the LV 1100, even though it's had the most time testing overall - used it both before my Odin restore and now using it after.
I can't explain why it doesn't get as good of battery life. May have just been a fluke day, but I'll keep testing and reporting the results.

Good stuff SK. Keep those reports coming. So true to say there is no universal best kernel, only best for you

yeah very good feedback sk! its always interesting to see that phone to phone, kernel to kernel there are so many variances in performance, stability, and battery life.
Dirrks 1200 sv has just been a rock for me. Never one lockup, reboot, and with moderate usage and taking the phone off the charger at 530 am (1 hour on the web, 20 mins on the phone, 10 texts, 30 mins of angry birds, some baseball superstars 2010, and a nes rom for 15 min, which btw i dont know how i get any work done looking at that!) I get home at 5pm with over 65% every day without fail.
In similar circumstances with my inc on an oc/lv kernel id be around 30-45% daily and it couldnt handle baseball stars at all with its gpu, and I thought that was great. My DX on stock speed would be in the same range as my sf 60% or so.

so do all the DO2 kernels have voodoo with them? Would the more stable LV 1100 or the slightly stronger 1200LV Be the better bet? It seems that whichever your phone seems to take better is the one to go with 
skibum1983

also does sv show more stability overall than LV? I would also assume that battery life is much improved on the LV kernels over the SV?

i cant really speak to performance on lv, saps, d13, sirkonan and others could better than me as my phone wont take low voltage.
from what ive seen some of the sfs out there (in the very small minority) wont run 1200 sv either. I will say all the sv kernels (all the kernels on dirks spreedsheet from his voodoo post are voodoo) 1000, 1100, 1200 d01 and do2 run completely stable on my phone.
lv was easy to see as a failure on my phone just by stress test in setcpu. within 2 minutes on all i was rebooting. the 1250lv would cause my screen to flicker and freeze.
