Since this article will not require a lot of explanation - I will "cut the crap" (so to speak) and get right to the point. Just to clarify, we were given this advice from a visitor who figured out a solution and we cannot grantee that this information hasn't already been published on the Internet - After searching the Internet I did not find an article of this kind... Apologies to parties involved if it already has been published online. This is why I'm going to avoid the words "exclusive" and "scoopage" purely because of the reasons stated above.
In previous beta and leaked versions of nVidia Detonator3 drivers, nVidia have given us the option of overclocking our TNT and GeForce graphics cards with a registry hack called coolbits.reg which enabled an option in the Windows Display panel to allow for core clock and memory clock overclocking adjustments (more information can be found here about overclocking your GeForce or GeForce2 graphics card). God bless the person who created coolbits, for the life of me, I cannot remember the creators name. When I downloaded the latest Detonator3 6.50 (and above) drivers and activated them, I realised that nVidia has in fact removed all overclocking options (thus trying to disable overclocking), even when the coolbits hack was executed again and again into the system registry. So, I set about hunting the registry for an option to re-enable the overclocking option, but to no avail after a long brutal stalking of the system registry.
The Oh-So Wonderful Cure
Whilst in slight frustration, I posted a quick question on the TT main page (10th January 2001) asking our visitors if they knew a cure to the problem I was experiencing. After this, I continued to try and find a solution, with still no luck. But, with a drastic turn of events, I got an e-mail from a TT visitor (Kerim) a few hours later which gave me all the information needed to enable the overclocking option in all Detonator3 6.50+ drivers. Here is what the user kindly e-mailed me:
"Using and older version of nvqtwk.dll is all you need to do for coolbits to work again."
So, you were expecting the cure to really painful and time consuming? As you can see this not the case and the solution is really quite basic.
IMPORTANT - The user did fool me a bit at first, after a little experimenting, I also found out you have replace the file "nvcpl.dll" to get this solution working!!!
I now know the files which handle the Windows Display overclocking options is nvqtwk.dll and nvcpl.dll - I should have really picked up on this a long time ago as it is really quite obvious, now I know about it. Anyway, to successfully re-enable "coolbits" and overclocking options with Detonator3 6.50 (and above) drivers all you have to do is replace the latest version of nvqtwk.dll and nvcpl.dll with an older version of nvqtwk.dll and nvcpl.dll (eg any version below 4.12.01.0649 - "0649" denotes the Detonator3 version, in this case it would be Detonator3 6.49). If you only have the latest leaked Detonator3 version stored on your HDD (which is 6.67) we have mirrored nvqtwk.dll and nvcpl.dll on our server for Windows 9x (ONLY) for individual download which will save you time instead of downloading a complete set of older Detonator's when you only need the two files, nvqtwk.dll and nvcpl.dll.
Once you have downloaded the new version of nvqtwk.dll and nvcpl.dll, you will need to place them in the following Windows directory... C:windowssystem - First, delete the original nvqtwk.dll and secondly replace it with the new (overclockable) version and thirdly reboot your PC for good measure.
PLEASE NOTE - If you have never executed coolbits into your system registry you will need to do so by downloading coolbits.reg and opening and click "Yes" to the prompt. You will again need a reboot. Also note, other Detonator versions can be found at 3Dchipset and Zoiah - I consider these two sites the best places for finding latest driver versions.
Windows 2000, NO GO!!!
Please note that is modification did not work in Windows 2000 during our in-house testing. After trying various versions of Detonator3 drivers, we had no luck with the modification on Windows 2000. With the modification in place, we experienced an error when trying to change the screen resolution... You are welcome to try this modification, but our testing shows it does not work, you have been warned. If you do decided to try out it anyway, we will not be held responsible if anything which may happen to go wrong with your system. However, you may be lucky and be able to get it working and If you do please let me know!
We hope this article will give you lots of hours of overclocking fun, with all versions of Detonator3 above 6.50. After all this, you may be wondering what all the fuss is about to get overclocking options enabled in the latest Detonator3 drivers? The simple answer being (generally speaking) all new Detonator drivers which hit the Net, be it beta or "leaked", perform faster then old drivers. And finally, has this downgrade in nvqtwk.dll and nvqcpl.dll versions got you wondering if it will equal less 3DMarks or Frames Per Second in games like Q3A? Well the answer is simply... NO. For the reason that these two files have no impact on Direct3D or OpenGL drives as they only serve as control panel files. We hope you enjoyed this article, do have some fun now kiddies! :)
