The answers to all of your questions are already in the forums, albiet, perhaps not all in the same place. I'll try to put them into one spot for you. The M919 does not work well with a 66 MHz FSB. 60 MHz seemed to be the fastest it was stable at. You will not be able to run 66x2 reliably. Some …

Please do yourself a favour and be sure that the ASUS mobo can feed the Voodoo 3 card with the needed current. If not you can damage your system. What is the max current draw from a Voodoo3-2000/3000 on each 5V and 3.3V rails? How does one determine the motherboard spec. for max current to the PCI …

Thanks for the test results. It seems like the G200 is just that much slower than the Voodoo2 in Quake II. To me the interesting aspect of the G450 was the PCI version because it contained a DVI port. It seems like not a lot of consumer-class graphics cards at the time of production had a DVI port.

For this experiment, I would say any G200 will do. But if you have, both, the AGP and PCI versions, testing each would be most beneficial in determining if low frame rate is due to the PCI bus. My benchmarks were on a PCI bus.

If you meant the results with the G200 are detailed in that document, I could not locate them. I do see, on the other hand, that you used a DFI K6XV3+/66 motherboard based on the MVP3 chipset and obtained roughly 66 fps at 640x480 with a single Voodoo2.

Mau1wurf1977, what fps do you get at 640x480? What motherboard/chipset did you use for testing? While I realise the Voodoo2 is certainly the preferred card for gaming compared to the Matrox G200, I did not realise the performance obtained would be nearly double. Mau1wurf1977, if you have a G200, …

Some boards run slower with a K6-2+ K6-3 than with a K6-2 plain one. Because of some bug or chipset / bios incompatibility, so you might face this problem. Is this phenomena not specific to the ALi Aladdin V chipset-based Asus P5A-B motherboard? Do you know which other 100 MHz FSB-capable …

JaNoZ, There aren't any GeForce cards which will work on UMC 8881-based motherboards that I have tested, that is, they did not even POST.

Mau1wurf1977, which desolder station do you have? JaNoZ, which hot air rework station do you recommend? JanoZ, why do you want the AM5x86 to run at 2x? I do not see much value in running such a chip at even 2x66 when 4x40 has better performance. At 160 MHz using a 27 MHz PCI bus, the 160 scores 17.3 …

Obtain an appropriate soldering iron, use the sharpest tip you can find, probably a Weller ETS tip. Use approx 440 C temperature to your iron for approx 3-6 seconds on the solder pad, then quickly use a solder sucker to suck out the solder. It may take 2 or 3 times per solder pad. Use care to ensure …

Every ADZ-marked X5 chip I've tested has run fine at 160 MHz. If you are having issues with an ADZ chip, it may be related to your CMOS timings.

I would recommend running the Quake 1 DOS benchmark for 3 rounds. If that is successful, try for an install of Win98SE. There was one user here who got that Biostar board running at 200 MHz and it seemed stable enough to install Win98SE and run several benchmarks without fail. He had to use 5 V to …

Those ALI and MVP3 boards are a bit of a disappointment compared to the FX, TX, and HX Intel boards. Have you maxed out all the CMOS performance setttings? Could you add a 2 MB cache MVP3 board to the mix to see if it can get a little closer to the TX's performance?

I beleive Amptron was PC Chips. Aside from them using a fake cache scheme, PC Chips 486 boards were not as bad as some people have made them out to be. The M919 v3.4 performs OK. It has some SCSI bus mastering issues that are tolerable as they are mostly an issue with W2K installations. The v3.4 …

I've programmed all 4 with different dates (same date, with 1-year offset) and disconnected them from the system. They'll be kept in storage for a few …
