I am pretty good at fixing PC's and figuring out problems, but I hear alot about "overclocking" video cards. How is this done? Does it really make a difference or does it shorten the life of the card? I wanted to try it on my "Toolbox PC" and see what happens. System specs.......... Emachine 667IR Celeron 667 CPU 40 GIG Hard-drive 256 RAM GeForce MX4000 PCI 126MB video card Creative Soundblaster sound card Windows XP Professional SP1 If it is not worth the trouble, then I won't do it. This PC will play Desert Combat at 800X600@60 resolution with settings on "low" at 50FPS, but I was just wondering how "overclocking" was done since I hear you guys talking about it alot. I know for a fact that the MB in this machine will not allow me to overclock the CPU though.

Usually Overclocking a video card is done through the drivers, or a downloaded program like Rivatuner or the ATI Tool. Since you have a Nvidia, you should already have the Nvidia Overclocking tool already built into there drivers, its called "Coolbits". You just have to enable it in the registry (Google it). It can shorten the life of the card, how much depends on how much extra heat its putting out.

I installed extra cooling fans in the case to keep the heatsink on the card cooler. Maybe I will try it.

Right click on your desktop, click Properties, click Settings, Click Advanced, then click "Geforce MX4000". If you have the latest nVidia graphics drivers installed, there should be a page for Temperature Settings. Check the temp of your GPU, and if its at a reasonable temp (check google to see what 'reasonable' is for your card), then google "coolbits", download and install the program. Go to the same page (properties-settings-advanced-GeforceMX4000), and there should be a new tab added called 'Clock speed settings'. Run the auto overclocking utility and your off.....

I am downloading Rivatuner to do it. I will try that first.

Here is a shot of Rivatuner utility. What should I set the core clock and memory clock to? I am kinda scared that I will mess something up! :uhoh:

It all depends on the temp of your GPU. Look in the nVidia utility page (showed you how to get to it above) and check the temps. Google your card to see what a safe temp is, or email nVidia. You can keep increasing the GPU speed as much as you want as long as the GPU temp stays well within limits. I still reccomend you use coolbits though, as it has an auto-overclocking utility that takes the GPU temps into concideration.

Yeah Coolbits has a nice Auto-Overclock feature, it can set your card a little high sometimes, but it will give you a idea of what you can expect to get out of it. After you set your overclock, run a game for awhile and see if you get any artifacting, if you don't get any after awhile your card should be good for the settings it was at.

Holy crap!dropsjaw.gif I set the setting up to about halfway up and I could not believe the performance! :naughty: I checked my FPS on Desert Combat and they jumped from 45 to like 65-75 FPS! Thanks for all your help guys! I would never have done this without your guidance! I am VERY pleased with the results! Someone told me that the MX4000 is based on the FX5200 and overclocking will not hurt it as long as you keep it cool! I have installed a 80mm fan on the back to draw heat out of the case to keep it all cool anyway!

Zalman http://www.zalmantech.com/ produce heatpipe coolers for graphics cards im not sure if yours is listed, and there may be other coolers such as Artic http://www.arctic-cooling.com/vga1.php
