I've been doing some bench marking on my socket 3 motherboards and I am consistently getting low memory bandwidth from speedsys. I am using mostly the same components when testing these boards. Example, the MS-4144, I was using a 100MHZ OD Intel and decided to try the POD83 and it made no difference …

I have this AGP Fusion 16MB that freezes and has lines when trying to use. I noticed 5 capacitors are missing on the back of the card, I don't know what the values are or the best place to buy them. These are ceramic capacitors I think? I've never replaced these type before. Edit: I also have a …

I have two VLB cards I would like to upgrade the memory on and I was wondering if there is more to it then that? On this Mach32 the capacitors are there but I don't know if anything else is needed? On the Hercules I was wondering if I can just solder on the 4 x 256Kx8? Thanks.

When I run my ELSA card at post the vertical lines are barley visible. After about 5 mins or so they are at their worst. What could be the cause of this? I replaced the surface mount capacitor that was on the middle of the board because it was leaking a little bit, but that made no difference. The …

I've never really done this before even though I've collected a lot of stuff of the years and I want to get started in sorting out my graphics cards by comparing the results of them. I have a few motherboards to do …

Sweet haul, congratz guys! I've always had a soft spot for Pentium Pro and Slot 2 stuff because I never seen much of it when I was a kid. I remember finding a dual socket 8 computer with NT on it at an estate sale in the late 90s, I had no idea what it was until a friend of mine that fixed computers …

Just my 2 cents on the Voodoo5 5500, I have noticed there is one user that bids on almost every single 5500 on ebay, the user has 1531 feedback and when you look at the bid history there he is on literally every singe one. Looking at the completed listings that user has won like 4 of them, it's …

Your thread has got quite subjective... it seems to go in different directions every time I go and comeback... and being 386 related, I like it! In answer to the thread title though, "the best 386 motherboard"... you have touched on one of my flagship projects. I believe the answer to this would be …

I did everything you suggested, it's just my luck and technique that's not very good. I know I'll never attempt this again. I did try and trace most of where they go, I was thinking of trying to fix it but I just don't want to spend countless hours wiring it up now. I guess my best option is to wait …

Here they are, not a pretty site, I'm sure if anyone else but me did this it would have been fine. The thing I noticed as I was cutting some of them were pushing and ripped really easy, maybe the problem all along was cold solder or the solder came loose off the pads, I probably should have tried to …

I tried my best but ruined the board, must have ripped about 20+ traces. I was so happy when I finally got a hold of this board, I've been wanting one for so long, now I'm sad. Do you know if it Is safe to run the board without the chip installed? will an ISA serial port card work without the chip? …
