Soft Modding ur old Consumer Nvidia video card.(Geforce 6800 and prior)
Disclamer-This tutorial is only for educational and testing purposes (mod only for testing).I take no responsibility if u damage ur video card during the process by messing up with settings.
Facts(first things first)-
Nvidia and Ati sell the same GPU with different names.The difference between these models is the number of vertex shaders and pixel shader pipelines or hardware\software masked units locked on them along with different fillrates(Higher fillrate=higher performance).This applies to geforce 7900 cards and perior.The actual thing is that during the production of video cards some hardware units turn bad resulting in graphical corruption or unstability so they are done away by locking them.The same is not the case with software units but they are locked due to pricing issues(higher software units=higher performance and same with hardware units).The good news is that u can unlock these for higher performance without the need of hard modding or bios flash.This works on Geforce 6 series(revision A1)or prior.(If the revision of the geforce 6 series card is A4 or newer it won't work.)
Second step-
Download rivatuner from www.guru3d.com
Install rivatuner(operating system must be Windows xp X-86 or 98se)Must have a supported driver
Run rivatuner-Then under customize click on low level system settings-Click on nvstrap driver click on install.Reboot the system.
Run rivatuner again then again goto nvstrap driver click on Use rom straps for PCI deviceID programming if u have a geforce 5 series or newer card this results in the loading of a driver prior to the video card driver during boot which acts as the video card's bios.Under graphics card identification select custom.Now u can select a custom card that has as additional pipelines which are locked on ur card.
E.G.-U can select a geforce 6600gt for a geforce 6600 or 6600le card.This will change the fillrate too resulting in higher performance.But if u experience graphical corruption in games u should select a lower series video card.
If u wanna manually unlock the pipelines then u can select customize under Active pixel/vertex units configuration(from the drop down menu to the right).Select Allow enabling hardware masked units then click on customize.Here u can manually select the unit to unlock.
Reason for this not working on Geforce 6 series cards with revision A4 or newer is laser locking which is nvidia's new technology to overcome modders(don't know how long it will stand).It severs the connections between the internal circuits rendering the pipelines non unlockable.
In case of hardware masked units the success rate is very low but for software masked units success rate is 97%.
I hope u like this information
and look forward for replies.
Is this a very common information or unuseful why not any replies??
Guys this is not that dangerous and u might get an excuse to buy a new card.
Please Let me know if u felt that this post was too long or something is wrong with it.
