If you keep within those limits and ensure sufficient cooling, you should have no problem running your card 24/7.

yes i know that because that is stock voltage, but im wondering how much v i vould run 24/7 on gpu and memories?
i have zalman ramsinks on memories and artic cooling vga silencer on gpu

Well thanks for all of your help. I finally got the rocks out of my head and laid down some serious graphite between pins 18 and 20. I got the voltage to about 1.8 which is fine for me, I was looking to get it above 1.58 which is really low if you ask me. My overclock is not stupendous (440/365) but it is faster than a stock xt which is where is was aiming at. One thing that I learned about this whole experience is that it is unwise to overlook the power supply as the culprit for low voltages and poor overclocks. With my old 420 I couldn't even get to stock XT speeds before or after the volt mod. Now with a new power supply and the pencil trick look where I am. I picked up a thermaltake purepower 420 for $36 (US) and it also helped with the Doom 3 speckle problem.

Again thank you to all who posted to help me.

Sorry, i didn't read your post properly.

With Arctic Cooling VGA silencer, i guess the highest voltage would be around 1.8v. as for the memory, 3.2v should be fine

Remember, i can't guarantee that with these voltages you won't kill your card running it 24/7. Some cards fry within a week with only 1.9v. Some feed their cards with more than 1.9v for a few months and the cards are still running fine

no problem

Glad that it works

runnin 1.95 for a month now

Remember, don't go over 2v even you are watercooling your card If you do, you are very lucky if your card lasts 2 months with that voltage

yeah i know that you cant guarantee that but its god to know how much i can run so i will probably test 1.8 and 3.2 and se the diffreses and then if i can oc much much more i will reduce it down to a good level
