overclocking a geforce 2 TI
(Click here to view the original thread with full colors/images)
Posted by: jacktheripper
HI,
i got a prolink geforce2 64mb TI and was wondering if anyone knows the safest levels to overclock it to as i dont want to kill it?
the overclocking facility built into it allows alteration to the cpu and memory settings currently at 250mhz core clock and memory clock 401mhz.i`d like to try it to see what it can do on madonion 2001 benchmark as when i ran it the scores were pretty average compared to some comparable systems with the same card..
also can the open gl settings be altered to improve performance?
CURRENTLY CHECKED:
enable buffer region extension.
allow the dual planes extension to use the local video memory.
THESE ARE UNCHECKED:
use fast linear- mipmap-linear filtering.
disable support for enhanced cpu instruction set.
other settings are:
DEFAULT COLOUR DEPTH:use desktop colour depth
BUFFER FLIPPING MODE:auto select
VERTICAL SYNC: on by default
ANISOTROPIC FILTERING:disabled
USE UP TO (5mb) FOR TEXTURES IN PCI MODE
DIRECT 3D SETTINGS:
MIPMAP DETAIL LEVEL:best image quality
PCI TEXTURE MEMORY SIZE:
use up to 31mb of system memory for textures in pci mode.
3D ANTI ALAISING:allow applications to control.
MY SYSTEM SPEC IS AS FOLLOWS:
xp 1700 with
256mb pc2100 ddr ram.
thanks....

Over-clocking is an art, no two cards over-clock the same.
I'd make sure you have good air flow through your case, and possibly consider adding a case fan blowing air down onto the card.
I would just over-clock your card a couple steps each way, then try your benchmarks and some games, make sure everything still works good.
If after some really strenuous gaming everything still works, push it a little harder and do some more heavy gaming.
BTW, it is theoretically possible to fry your card just attempting to do this.  And you will void your warranty.
Eventually, you'll find a point where your system will do one of two common things.
One: the whole system freeze's at some point, commonly, either just after loading into Windows, or after you just start playing the game.
This can also wait some time, and kick in say, after 30 mins or so of game play.
Two: when gaming (even in Windows sometimes too) the screen starts to look really screwed up. Random multi-colored lines or specs show up on the display, showing you that the hardware can't take the clock settings.
It will take some time to find your cards sweet spot.
After you've taken' your card to the breaking point by pumping both the core and memory a couple steps a time together, back em' both down a couple notch's, (and I don't mean the notch's that are graphically displayed on your screen, I mean a couple clock frequencies, like 2) then try pumping them up individually. Chance's are one of em' is gonna' give before the other will. (Usually the memory.)
As far as the settings, 16bit color will most always be a little faster than 32bit color.
Enabling the "Use fast linear-mipmap-linear filtering" option should speed things up a bit at the sacrifice of quality.
For speed, Anisotropic Filtering should be left off. Any other setting will increase texture detail at the sacrifice of performance.
Under the D3D tab, try setting your Mipmap detail level to "Best performance".
Let me know if I was un-clear on anything.
And good luck, just take your time.

or 3.) It overheats to the extent where it fries.
