Just booted pqmagic for dos and extended the 8gb partition all the way to 140gb and got this now. I’m shocked. I thought windows 95 would never do this..

Almost certainly this is a memory density issue - but to be sure we need to know what chips are on the DIMMs you are trying to use. Via MVP3 chipset can handle max 128Mb (note the little b - you need to be sharp & consistent on capitalization as chip densities are indicated in bits whereas DIMM …

Btw, feiopa. If you wanna open up my latest screenshot in paint and draw the traces on that overhang it would save me time when I get a chance to mess with it again. (Save me from having to study the datasheets to see what goes where on that fet lol) Don’t draw any traces for vcc5, vcc3 or gnd. Just …

Looking really slick. yes, I was planning on finding a way to get a more precise measurement either this evening or the next. EDIT: How much of an overlap does it say there is? Not much, about the width of a processor pin. It is entirely possible that the courtyard is wrong. Just get me your …

I found the mobo in question which I thought I had stored with ram installed, unfortunately It was removed. What I remember is this: stick one 256mb double sided stick two single sided 128mb Max board ram seemed to be 384 and not all sticks matching that description worked on it. So it is best to …

Can’t believe I got it to format a 128gb partition. In fdisk it was saying 13gb but took forever to format. I went and formatted it in windows and boom! 128gb (probably because of limitations of fat32) I am still using a primary 8gb partition for windows 95c

Try other sticks. You are probably going to be wanting to use double sided. You may have a max of 384mb I have a similar board set up for 384, I can show you the sticks I used in it. You could try ordering them? I had to go through a pile of sticks to find the best configuration for 384mb which was …

I’m in favor of a three pin fan header if it will fit, but it’s not the end of the world to not have it. I like how a three pin plug will hold more firm to the header than a simple two pin will and the fact that most of us have drawers full of three pin fans already. Those wanting to use a two pin …

Yeah, those cooling/center tabs are sometimes live. We may be energizing the processor heatsink. Which is what may happen to a clip on heatsink also of course. Moral of the story, don’t let tab or things touching tab touch metal stuff Okay if we are aiming for a specific spot left vs right and …

Now that it seems I worked out the bugs, I reassembled the gateway 2000 in all its upgraded glory! I ended up having to change the scsi dma channel to 7 after moving the card to the psu side with a network card below it.

Here's another image. I don't think we'd want to make the overhang any larger. So perhaps either rotate the caps around, or using the smaller 1206 size noted on page 13? image.jpg I assembled as you suggested and then did a little re sorting to make things fit better. Thoughts on this modification …

Okay. Just so you know though, there isn’t really a need to have the caps over there if they are in the center already. I’ll throw that design together so you can take a peek.
