Today I purchased a MB 486, I thought it was an EISA ISA, in reality I discovered that the EISA is an OPTI, I honestly don't know what the difference is, could it be the same thing? It already has some 30 pin RAM, some L2 cache chips, I think it's 128KB, and an Intel 486DX2-66 CPU, I don't think …

Hi, Welcome to the forum 😀 Please provide photos of such card. Maybe you just happen to have 4Mb variant? Have you checked datasheet of Ram chips?

Hello there! I think you're trying an ESS cards that doesn't have DOS support. I'm not an expert, but from what I remember, there was a video that Phil from Philscomputerlab did, and he mentioned about something that ESS cut support starting from the Allegro card and onward, so the last DOS card …

Do you have an ESR meter? Some multimeters will measure Capacitance. Also there are those cheap cinese LCR-T4 testers that are quite good for testing capacitors. Maybe you could pull out 3-4 capacitors at random, especially those near the CPU are and see if they still are good. The board is from the …

From my testings the Virge/DX cannot run 3Dmark99, you can use Final Reality (on board accelerator) if you want to test the card.

@Karbist Thank you so much!! @Horun Yes, indeed, need to do that, but writing everything on a piece of paper seemed more "professional" 😀 @CharlieFoxtrot we're on the same boat brother 😜

Hi all, I had previously received this lovely and quite rare AM2 Motherboard with AGP slot. Unfortunately it had many bulging caps and decided to recap it. The new caps have now finally arrived but I can't seem to find the piece of paper I wrote the values :( I kindly ask if someone has this board …

I changed it this morning. Found the component on a broken board and replaced. It worked on first try. Again thank you very much!!! Given the limited space and my cheap soldering tools it came out ok 😁

In my opinion the Voodoo 3 3000 is best served on a S370 board (Via Apollo Pro 133A chipset) with a Pentium III (800-1000MHz). One good example is the ASUS CUV4X but might be on the high price. Similar boards with that chipset can be found easily and for better prices.

You could also try the old hack of thermal paste with acrylic super glue. Big blob of thermal paste on the center and 4 small blobs of glue on each corner that makes contact with the CPU. Hold it in place for a few seconds and you're good to go. It hold surprisingly well and it's not that permanent, …

It could be a problem of the Ramdac. If you have another ISA card you could try. Usually these Ramdacs even though are different parts, most of the time they are just clones of each other, just look for another chip with "476" on top.

Sorry to hear, don't worry though, it can happen. It was a board used for testing in the end, it's what was meant to be used for.

Yes, that is the one, be very careful. It is very easy to break that socket if you do it to fast or apply too much force.

Have you tried reseating the BIOS chip? It's legs are often corroded from time and it won't make proper contact to the dip socket. Try removing it gently by applying tiny force on both sides with a screw driver (be very patient because often is very hard and when it finally gives up it tends to bent …

There is a video of PixelPipes on YouTube where he changes a couple of caps on what seems to be the same exact card. So when increased the resolution, and stopping the video just at the right time you can almost see what the value is. I believe is L42 like you said. See attached photo

And I must say I didn't encounter the problems described. I've tried plenty with various chipsets (Intel, SiS, VIA) and so far they have been rock …
