can anyone tell me the basics of GPU OCing?

[theholylancer]

anyone? like in cpu i need to set jumper or go into bios and set fsb or multiplier until can't boot and increase VCore Voltage then redo, now how about GPU OCing? i'm trying to get a evga e-Geforce6800 GT 256 MB one and looking to OC it with stock cooling or some cga cooling (no idea what is good in this area please recommand)

um are they software or hardware adjuestments? as in where to se this speed? (i think i try wikipedia for the names ya mentioned )

Just remember to not go to high on the vcore or it could,and if high enough damn sure will burn out your chip and melt everything around it lol.

Stuff like coolbits doesn't let you change the GPU's voltage. for that you need either a hardware mod or a reflashed BIOS, depending on the card.

hmmm ok, i think i run my vid card fisr on stock speeds and see how hot it gets and i come back here and ask ya guys

 

[tenaciousleydead]

Ya well you can usually change the voltage in the bios(depending on motherboard) my other MSI board went to 2.4 volts.

Hey! a man can dream! and couldnt that ozc thing up the voltage for ram to 3.2? sometimes its better to not know what im talking about so i dont care, have fun!

No motherboard BIOS allows you to increase your Gfx Card's core voltage. A lot let you adjust the AGP voltage, but that don't do much really.

Overvolting a GPU is a lot more 'hands on' than any stuff on the mobo (RAM, Chipset, CPU, etc).

awww crap i hope i don;t need to be wusy to do this...... [/scared]

 

[theholylancer]

well first i will need to get a melting stick thingy (soldering gun?) as that i'm not big on these things.... and hopefullt it won;t melt through the damned card!

 

[tenaciousleydead]

buy it back when what? great price thought got the mobo and barton plus a volcano 11? for 30 bucks.

wusy ur linky don;t work

o and my card is a 6800GT and my mobo is a DFI lanparty UT NF4 ultra-D so i think that hte extra power pins for elite graphic card will help me if i want to OC to ultra speeds<P ID="edit"><FONT SIZE=-1><EM>Edited by TheHolyLancer on 08/04/05 01:28 AM.</EM></FONT></P>

I think - and no doubt someone will correct me if I'm wrong - That the 6600GT you're talking about will actually only involve flashing the BIOS, and not soldering... Which is a good thing.

I wouldn't worry too much about voltmodding just yet. just see how far you can push the card at stock voltage first - you may get lucky..

Oops. I read in the first post that you were looking at a 6600GT, but you later say a 6800GT... well, my previous post still stands....

I did just notice in that first post you say you want to stick with stock cooling. In that case I wouldn't do a voltmod. Only do so once you've improved the cooling, if ever, IMO.
