I installed PAC(KitKat, latest nightly) on my GT-N7000(Galaxy Note) which has 778mb available RAM, and I get around 380mb used after clearing recents, and 355-ish after the phone has been at rest for some time. Mind you I haven't got too many apps installed which have background services, though. But I'd still say it's good RAM management.
But as for what you should do, I think you should take @iamashwin's advice...He knows what he's talking about. :cool:

I also suggested the same thing(to use stock rom) if you have read my post carefully.

In recovery, do factory reset and data wipe. Should help.

As my friend @AA1973 once told me, a full wipe is a last resort option...'last exit Brooklyn' ;)
But yeah, it should solve kernel-flashing problems...and since you can't boot, it's probably your best option now...:good:

Follow these steps , so that it will not cause bootloop :
1) reboot into recovery
2) do not wipe anything otherwise you will loose all your installed apps(if any) as you have cm 10.1.3 already installed
3) flash cm 10.1.3
4) flash gapps
5) flash agni kernel that is for android 4.2.2 not cm 11

6) wipe cache and dalvik cache now

    Thanks for being always here to here . As I told you I'm an amateur and I don't know how to install it . I'm also afraid from Ram usage of this rom ! My brother have a samsung galaxy s4 with 4.3 android and its ram usage is 700mb while it is stable and in galaxy tab 2 I only have 769mb ! So would I have such a ram usage if I Install this rom ?

    Bro stock rom is know to have battery issues and ram leaks as it has a lot of apps and unwanted files (commonly called as bloatware )
    1st i noticed tha tu have 769mb ram so you are still in stock kernel (i guess) first flash a new recovery from here http://xdaforums.com/showpost.php?p=51314025&postcount=296 next flash Slim Rom(u can use any rom but as the name suggest it is verry fast and smoot and also hasa good battery management) from here http://www.slimroms.net/index.php/downloads next flash gapps from there itself .next flash a kernel such as Agni (highly recomended)

    First thing you should know, you don't havta say thank you all the time, just click the Thanks button, that's what it's for. :D
    And I actually installed PAC ROM today. It's an awesome ROM with a lot of cool features...
    As for RAM usage, I dont think that should be a problem. The ROM should be optimised for your device, so it won't use 700mb at rest. :)
    Give it a try, if you find it's slow or laggy, I can suggest more ROMs. :good:

    (<---Remember to Thank me if I helped)

    "Borther. I would like to quote one thing first of all; all kitkat based ROMs are battery suckers. So you will not get good battery backup as you might have seen in 4.1.2 or 4.2.2. Xposed framework consumes lot of RAM,i prefer not to use it. PAC ROM is just like another KITKAT ROMs that provides loads of features but with an inefficient battery backup. You will see huge battery drain yourself. I did tried all Kitkat based ROMs. Even all kitkat based ROMs have shuttering/noise sounds while playing some games like Real-Racing 3 etc. I suggest to go with Stock ROM 4.2.2 based on your region or cm 10.2 based ROMs(if available). Root it(if stock) and remove all the samsung bloatwares from it. Then you will not get any kind of battery drain or Lag while playing high-end games. But ultimately choice is all yours."
    Thats why am still confused ! So what is the usage of ram at rest ?! You install pac rom kitkat or lower version ? What about battery , did it drain too fast ?!
    And how did you install it please !? Am running sg tab 2 p3110 with SuperSU root and the latest version of philz as a custom recovery :)
