Overclocking

[gordesky1]

guys i got this coolbits for overclocking i just like too know whats safe too raze the card too like in core and memory? this is a geforce 4 420mx with a fan?

[Daishi]

wut i usualy do is i keep overclocking till i see artifacts then i usualy go down a few mhz till there is no artifacts then go down another 3-5mhz on core and mem to be safe.

[gordesky1]

what is artifacts will they show when i hit the test button? i just dont want too blow out the card the defalt setting is 250 core and mem is 338

[gordesky1]

what whould you think whould be safe for this card?

[mikedick6969]

You wont know til you try it. Every card is different. You'll see artifacts. You wont miss em. When your screen looks garbled, anbd theres stuff there that isnt supposed to be, thats artifacts.

[gordesky1]

will it hurt the card if i see them than turn it down?

[mikedick6969]

It might if you just left it like that. If you change it after seeing it, you'll be fine.

ok thanks

ya ull notice right away. if theres like a person and they got some crap stickin out their head thats not supposed to be there ull know heh.

typically its harder for you to blow a card cause they get too hot and stop functioning and will work when you start your system back up.. if you over overclock it you would get garble on your screen in which you know you went too far.. at least thats what i expierenced with my geforce and voodoo

ok i got it a 320 core and 350 mem and it play good but will the fan on the card keep it cool?

I have a Chaintech, GeForce FX5200 128mb (Nvidia) card.

 

When I was having problems, I emailed tech supt at Chaintech. Here is a copy/paste from their reply email on MY card:

----------------------------------------------------------------------------------

Try and clock your system with a core that is 10% of the orginal value

and 20% for memory if you have a default fan.

 

Than run 3dmark2001se and see what you get.

----------------------------------------------------------------------------------

 

I am not sure how that relates to your model # card but I thought it might give you some ideas. BTW I do have a fan on my card also.

 

I read somewhere that you should never overclock the core more than 10% (I will try to find that quote and post it).

 

I have experimented with my card and got in trouble a few times. Be carefull to only notch it up a few #s at a time. When you start seeing stars or snow flakes or lightening bolts shoot across the screen that don't belong there STOP and ratchet it back 3-10 points. It's safer to experiment the memory than the core.

 

3dmark2001se is an excellent test for your card. Make sure that you use something like that to test it.

 

If you go too far, you can screw up your BIOS and and all kinds of wierd things can happen. One time, I went too far and the monitor blacked out suddenly. I rebooted and it seemed to start the rebot process oK, then all of a sudden, black monitor. No matter what I did, I could not get into my BIOS, safe mode, nothing. I had to go out and buy a new hard drive, install my OS and programs. I could then boot onto the new HD and transfer my files and settings.

 

That was an entire day and $70 wasted because I went too far with overclocking the card. It didn't hurt the card at all. All I am saying is, you can do a lot more damage then just hurting your video card. Be careful.
