Welcome to the forums kalamar182!
My 3770K's (three of them) could get to 5GHz stable for 24/7 operation, but I never left them there because the voltages were way too high for my comfort level.
They run comfortably at 4.7-4.8GHz.
Delidding doesn't really seem to bring much in terms of increased overclocking potential, but it does dramatically lower the operating temperatures which will substantially increase the lifespan of your already over-stressed CPU (because it is overclocked/over-volted).
Great... i am follow your steps rigth now, im traying to figure it out how to separate 2mm from the cpu water block and the cpu i have a rasa cpu waterblok. Thatsthe only thing thats stopme. I.m excited to se the my temps. I oc my i7 to 4.8 stable with 93 max temps i really need to get low that temps.
Sorry but can you sendme the link of the complete tutorial??? I am only with my phone and ints not easy seee sow many pages and comments.
Thanks and again....sorry my english
