I'm running an experiment with VIA MVP3 boards and I have yet to get an MVP3 board to run at AGP 2x with any Matrox card. Let me preface this by letting you know , I don't need to know what cards will work or that early VIA chipsets have problems with AGP, or that there is very little real world performance difference between 1x 2x and 4x. The experiment is to get one running at AGP 2x. Sisoft Sandra shows that before I install the driver, the board and the card are running at AGP 2x. But as soon as I install ANY version of PowerDesk drivers it drops to 1x. It's not a chipset issue since it shows 2x before driver install (I have tried 8 different versions of VIA 4 in 1's just to check) I have 5 different MVP3 boards. I have tried G200, 400, 450, 550 Milleniums and Marvels... same result. Recognizes 2x before driver install and drops to 1x after! Google searches don't show anybody mentioning this problem and yes, the cards operate fine at 1x but are all 2x or 4x capable. Also I have tried powerstrip but it only lets you lower AGP speeds. All higher speeds are greyed out once the driver is installed. I was wondering if anybody else has got a Matrox card to run at 2x on an MVP3 board?
