What happens if a 650 TIB is OC'd extremely?

Um. The magic smoke will probably be released from your GPU, and warranty won't cover it.

It'll just shutdown the PC because it wont receive enough power to run the card at that speed. However, if you adjust the voltage control too aggressively, you will cook the card. I suggest not playing with the voltages unless you are experienced at overclocking.

you said it yourself that you are new to this. With that, it's a bad idea to be even thinking of "extremely"

If you did what you just said, you don't know what you're doing. Unless your intention is to fry hardware.

I also extremely OC'd my GT630 and it's now gone.

You destroyed your card by OCing it too far. I don't call that a blue screen, or data loss.

But then what happens is your games won't last more than 10 Minutes though they will have weird flashing objects and serious graphical errors.

AKA artifacts. A serious sign that you are damaging the silicon.

Also, you haven't mentioned the words 'stress testing' once.

IMO the op is being retarded. A person who does not learn from his/her own mistakes the first 2-3 times clearly is short a few rocks.

This is what you should do op.

1) Research overlocking to the full extent to where you don't need to goto forums and ask why the smoke came out and how to put it back in.

2) start with small mine-ute advances in the clock speed the stress testing for no less then 24 full hours.

3) heed the advice of others who are for all intents and purposes godlike to your own intellect.

4) Understand that while there are various versions and re-iterations of this card due to it being voltage locked on the hardware side there's is a very limited range to which the card can be stably overclocked. Of Which you should Never Need to Exceed!

A) Core Clock of +150 (NOTE SUFFICIANT COOLING AND 110% POWER IS NEEDED)
B) Memory clock of +300. All memory to current date is DDR (Dual Data Rate) this means that there are multiple IC chips that run in parallel hardward configuration giving the illusion that it runs at a 6Ghz speed. This is a marketing ploy and you should not be trying to catch that mark as you will fry the chips.
C) Set a User defined fan speed curve. It should be a rather dramatic curve since you clearly do not know what you are doing. I highly recommend using the following four points. 40/30, 60/50, 80/70 and lastly 100% @ 80c. This gives you the default fan speed at a cold idle of 30c of 40%fan and will increment 20% every 20degreesC. With this control set you should never breech 60c and you still wont notice the fan at 70%.

Finally; Start with a simple over clock. The GPU shouldn't need to be overclocked at all. While you can you only reduce the life of the card when you do. Start with 3100Mhz Memory, Leave it at that. Go in to what ever game you wish to play and turn up the texture settings to the max. Play for a bit and see if you notice any lag if you do then you need to turn down the video settings a bit, start with lower shadows as they are always the main source of video lag. Then turn down from 8x/16x to 8x/12x , 6x/12x then 4x/8x. At no point should you be trying to clock your card to reduce the amount of lag while under ultra high settings in any game. Once that is stable you might try a Small increase in the core clock +25-30Mhz should do but no more then +50Mhz Remember This Card Is Voltage Locked and it will only try to draw more current the higher you clock it with no further voltage coming in it will either over heat and melt some solder points or it will crash to a memory dump. Either way its extremely bad!

Always Er on the side of Caution and carefulness when over clocking.
