Overclocking nVidia Cards.
Overclocking nVidia Cards.
Most of us own a nvidia card and want to get max out of it. So.....why not overclock it??
Is overclocking dangerous?
Most people think its dangerous. But well..... let me tell you its only dangerous if you do it, the wrong way. So just follow instructions and you won't blow your card.
What do I need for Overclocking??
Things that you need to get/download before you start overclocking.
1)A nvidia graphics card. Duh!
2)Foreceware Drivers. (I recommend v92.91 for best performance)
3)CoolBits. [ *downloads.guru3d.com/download.php?det=815]
4)Riva Tuner [*downloads.guru3d.com/download.php?det=163]
5)rthdribl [*www.daionet.gr.jp/~masa/rthdribl/]
6)NV Temp logger (google
)
7)3D Mark 05, 03
8)ATi Tool [*downloads.guru3d.com/download.php?det=725 ]
What is gfx card overclocking dependent on???
Like processor overclocking depends on various things like ram,motherboard etc...Its said that graphics card overclocking is not much dependent upon anything,however you do need a better SMPS and cooling.
Things to do before overclocking. Check if your card is capable of getting Oced!
1)Start nv temp logger.
2)And run rthdribl or a game like NFS for about 1hr and check the highest temp. If it exceeds 75 degs then read no further, without better cooling!
3)Run 3D Mark 05 and note down the score.
Finally, “Overclocking”!
So this is out to OC your card.......
Method 1 :- CPL
1)Double click on CoolBits (the .reg file you downloaded) And confirm “yes”
2)Right Click on desktop--->Properties------->Settings Tab---->Advanced---->gofore xxxx (xxxx will be your cards modle number).----->Clock Frequencies.----> Manual Overclocking.

3)Increase the clocks by 10MHz each time and clock on “Test Changes”
4)Now run rthdribl for about 10mins and check the temps and Stability.
5)If the temps are under control then repeat the step 3),4)
Method 2 :- Ati tool.
Its designed for ati cards but works well with nvidia card if you stay away from options like “Find max Core/mem”
1)Start Ati tool.
3)Move the “3D Perf” sliders and Hit “Scan For Artifacts” let it scan for about 5mins.
4)Repeat the step 3). if you get through.
5)After you get a sweet spot. Scan For Artifacts for about 2-4hrs.
When Should I stop?
You should stop when you see any Artifacts in games. Or if your system freezes. Or any kind of texture corruptions.
Cooling????
Third Party graphics card coolers are available but may be expensive and may not be easily available . So you may make use of normal 80mm fans. Just fix it on the card.This may be a test of you moddin skills!
But it will really help to bring down the temps.
Core>Mem or Mem>Core?????
Well....it depends from card to card. For eg> Cards whose memory is not passively cooled ..go low on the memory. But for card's with heatsink over the mem it shouldn't be a prob.
Is there any performance gain???
So....you finally Oced your card and want to know the performance gain??
Run 3D Mark and tally it with your previous score.
Caution: Dare to do this at your own risk. I,digit or the manufacture don't take any responsibility for any damage caused to your card!!!
