ATI CATALYST AGP DRIVER



AGP problems can cause random crashes or hangs in 3D modeimmediate crashes or hangs upon entering 3D mode, image corruption, turning ATI Catalyst AGP your monitor, freezing your computer, and just about anything else you can think of that involves a video card.

AGP causes problems most often in 3D mode but it can sometimes get into trouble in 2D mode. On most computers, it works fine. But a surprisingly large number of computers have unreliable AGP ports. If you are seeing just about any kind of reliability problem which could possibly involve an AGP card, you should always try to slow down your AGP port to see if it solves the problem. The reason that full speed AGP and fast writes tend to be flakey is because they are transfering data like a bat-outta-hell. Basically, that's pushing the envelope, electronically speaking, if you're talking about low-budget consumer hardware where they're trying to shave every nickel off of their bill of materials.

If you've ever seen high-speed scope traces of that data, it ain't exactly perfect ones and zeroes. If your board is laid out and decoupled properly, and the CPU, northbridge, and GPU are all nice and cool, and the power supply is keeping the rails relatively smooth, then it probably works just fine. But if any one of ATI Catalyst AGP links in the chain ATI Catalyst AGP a little weak, then you've got problems. There two main things you can adjust to try to stabilize your AGP slot are: If you have an overclocker motherboard then you can probably also increase the AGP signaling voltage. Technically, there are many more AGP adjustment tricks, but those are the main ones which are most likely to solve problems and most of the rest require diddling obscure options in your BIOS.

By default, most AGP cards are initialized to the highest multiplier supported by both.

Unfortunately, that speed can be flakey, especially if it's 8X. There are various programs described below which allow you to select the AGP multiplier. Just take ATI Catalyst AGP AGP multiplier down to the next lower speed and then test for a while to see if your problem is solved. If not then move down to the next multiplier.

Most of the programs also allow you to disable AGP mode altogether by offering a "PCI" option sometimes called "off" when selecting multipliers. Do not take ATI Catalyst AGP multiplier to a higher value. The point of this exercise is to see if slowing down your AGP port can improve stability.

It's not to see if you can speed up your AGP port. Only use multipliers which are at or below your default multiplier.

If it turns out ATI Catalyst AGP using a lower multiplier solves your problem, then you have to accept that it will cost you some performance to use that solution. And even cutting back to AGP 2X isn't exactly going to devastate your game performance if your video card has a fair amount of RAM on it. And outside of games, the speed of your AGP port makes very little difference. Fast writes have acquired a fairly bad reputation. They can be the cause of quite a ATI Catalyst AGP of flakiness.

On top of that, ATI Catalyst AGP most cases, they don't improve real-life performance by very much. If you really want to play it safe, you can just disable them and forget them.

My opinion is that if fast writes are currently enabled then you should leave them alone while you try reducing the AGP multiplier. Fast writes transfer data at the same speed as the AGP multiplier so if fast writes are flakey, there's a good chance that the real ATI Catalyst AGP is that your AGP multiplier is too high. Once you lower the AGP multiplier, fast writes may start working properly. If fast writes are disabled by default, then don't try enabling them. They may be off for a good reason. If your fast writes are currently enabled and your problem isn't solved by trying the slower multipliers, then disable fast writes and run through the multipliers starting at your default multiplier again.

In a lot of cases, lowering your AGP multiplier to ATI Catalyst AGP stable value will make disabling fast writes unnecessary. Please note that there are some cards apparently some kinds of Radeon s and possibly others which have performance problems if you disable fast writes. If you find more than one combination of AGP multiplier and fast writes which is stable, then just run some benchmarks and pick the combination with the best performance. The AGP signaling voltage is the voltage of the signal used to transfer data between the AGP card and the motherboard.

You can sometimes stabilize an AGP port by increasing the signaling voltage.

Only motherboards designed for overclocking are likely to support increasing it. There are two voltages which may be supported by motherboards: If you have a very old motherboard then it probably supports only 3. ATI Catalyst AGP newer motherboards support both 3. Most newer AGP motherboards support only 1. ATI Catalyst AGP Catalyst™ Driver Download for AMD Radeon™ AGP Graphics One of the following errors may occur during installation of the AMD Catalyst.
