**NOTE**

This trick does not work under Windows Vista

Here's what you need:

-A video card with Turbocache (duh). It pays to get a card with more onboard memory, like 256MB

-The latest nVidia drivers. You might already have these. I use Forceware 93.81, but I think the latest stable will work too.

-Rivatuner

Now, down to business:

First, install your video drivers. You've probably already done this, but if you want to make sure that you have something recent, do the following:

-Right-click your desktop and click Properties

-Go to the Settings tab

-Click the advanced button

-Go to the Adapter tab (note the Memory Size under Adapter Information)

-Click on Properties button

-Go to the Driver tab

-Check the Driver Date and Driver Version to see if it's at least November 2006 and/or 93.71

-Close the dialogs.

-If your version isn't up-to-date, then download and install the latest nVidia Driver.

Install Rivatuner

-Just download it from here: http://downloads.guru3d.com/download.php?det=163

-Run the installer

Hey, that was easy, right? Now comes the important part:

-Disable Turbocache

-Open Rivatuner

-Go to the Power Users tab

-Click on the Open Matched Database button. It's one of the little ones on the bottom.

-Find and expand the nVidia...System entry in the list

-Find RMDisableRenderToSysMem and set the value to 1

-Close Rivatuner

-Reboot the computer

Double-check to see that your card is "normal" and not using system memory anymore. Repeat the "Verify your driver" steps to view the properties of your video card and see if the memory listed is only what's onboard (up to step 4).

And that should be it! I noticed a performance gain on my system. Probably because it wasn't paging to the system memory. Probably just one less thing the CPU had to keep track of.

If this makes matters worse for you (which I can't imagine that it would), the just go back in and delete the 1 value for the entry in Rivatuner, and you'll be back to the way you were. Just remember my standard disclaimer: you did it, it's your fault!

Q&A

*Q: When I click on the "Open Matched Database", the program says that "Riva Tuner cannot find the database for Forceware XX.XX. Do you want to open database for the closest driver version?

A: Click on "No" and skip that step.

**Q: When I click on the "Open Matched Database", the program says that "Riva Tuner cannot find the database for Forceware XX.XX. Do you want to open database for the closest driver version?

A: Click on "Yes" and procceed.

*94.24 Forceware

**Below 94.24 Forceware

I have gotten myself a GeForce 7300 GS 256MB DDR2 with Turbocache that enables 512MB, and like always when I get new things, I was excited to try out my new video card, so I went and test it out on Battlefield 2142 and it turned out to be extremely horrible, same goes for FEAR, Battlefield 2, Counter-Strike: Source, and Doom 3. Now with the Turbocache disabled, I am now able to run almost everything on high running at 1280 X 1024 and I'm not joking here and heres proof on my DxDiag: untitled39ww3.th.png

1280 X 1024: untitled1ip7.th.png - 50FPS

1024 X 768: untitled2es0.th.png - 30FPS

1024 X 768: untitled3ki1.th.jpg - 30FPS

1024 X 768: untitledvt9.th.png - 40FPS

CPU Score: 951

Please no negative comments, I'm still learning.

and then jump to

i was looking for that option:

RMDisableRenderToSysMem

and never found it also expanded and looked on all tabs and cant find it

my forceware version is 94.24 under this system:

Pentium D 3.20 Ghz

1024 MB RAM DDR 400Mhz

250 GB HDD SATA

NICE! 30fps on bf2142 with that 7300 GS Card, i need a new card and might consider that one! i have bf2142 and i get lag all time, even on LOW ALL!

But is turning of Turbocache any better or does it actually loose performance, i suppose if your a high gamer:

Turbocache ON

If your just working on the desktop etc..

Turbocache OFF?

The option should look something like this: untitleddv5.th.png

If you still can't find, try installing an old Forceware and if the problem still persist, we'll have to manually disable it.

Yes and no, it depends on game wether it uses 1GB of RAM or not. If the game does use 1GB of RAM and you have Turbocache enabled, your game will stutter and major FPS drop, but on games like Counter-Strike: Source that uses around 512MB ( I believe it uses 512MB ) then Turbocache should improve the FPS by 1-5, so thats not much. To me, a high gamer should turn it off.

If your just working on the desktop etc..

Turbocache OFF?

If you are asking is it good to leave Turbocache off when you're only using the desktop, yea, it doesn't matter. Or if you're asking if you disabled Turbocache will it still be off when you're only using the desktop, yes, it will still be off.

This is what Turbocache does, if you have 512MB of RAM on your system, the video card will steal 128MB away from your 512MB, thus making your RAM 384MB and your Video Card 384MB. If you have 1GB of RAM, it will steal 256MB from it and making the video card 512MB and your RAM 768MB, so games that requires 1GB of RAM is better off disabling Turbocache while other games that uses 1MB-512MB its okay to leave it on but it will still stutter once in a while.

Hello again :) thanks for your support and i finally make that work installing an old version of the Forceware and easily change the option. My video card now says i have only 256 vdeo memory, but i have another problem: windows properties keep saying i only have 768 MB of RAM i guess when i enabled this option only says i have 256 but still keep using my RAM as Video Memory! anyone know something about this? or i did something wrong? thanks for the answers :)

If you have 1.5gig of ram. Does TC improve or hurt ur gaming? I play Counter strike source

7300gs

Since you have 1.5GB of RAM Turbocache will improve your perfomance a little so if I were you don't turn it off.

The 8500GT doesn't have Turbocache which is extremely good, so your card itself holds all the 512MB

My laptop has 2gb of ram and the video card is an 8600GS with TC. The card itself has 256mb of ram, and it says that when you have 2gb of ram it will let it use up to 1gb of ram. Should I turn it on or leave it off?

The 8500GT isn't on the Turbocache list: http://en.wikipedia.org/wiki/Turbocache

If you're using Windows Vista it would be better if you turn it off, if your using XP just leave it on.

I finally had time to do a benchmark with Turbcoache disabled and enabled and here's the result:

Turbocache Disabled

669 3DMarks

SM2.0 Score: 252

HDR/SM3.0 Score: 222

CPU Score: 951

Turbocache Enabled

680 3DMarks

SM2.0 Score: 259

HDR/SM3.0 Score: 224

CPU Score: 952

Though I still say that if you just meet the mininum requirements for a certain game on RAM I'd say disable Turbocache.
