Memory testing, round 3.. fight! 🧵

So, first of all, the Pacman PC passed its tests with flying colors! Woot! I'll leave it at 1GB for future fun.

As such, I've moved on to the CompUSA PC. It has an Intel SE440BX-2 motherboard. Oh, here we go again, that i440BX chipset. Also, looks like the manual and The Retro Web disagree here on max memory, but I bet with the right kind of 256MB chips, we could hit 768MB.

Alright, let's be obnoxious and pop in these PC133 256MB DIMMs. That didn't work. So I popped in some PC133 128 MB DIMMs (not pictured, sorry! I forgot to snap a pic, and am being lazy šŸ˜‚)

So far, MemTest86+ is off to a good start! As I write this thread and look at the screen, it's at 37% , so I think we will be ok!

While I was here, I wanted to see if I could put that really goofy chip in, but alas, as @Sparcie2 noted earlier, it's different. I've put a standard PC133 DIMM on top, and we can see that one of the holes is "one pin different." Okay, I guess we don't get to test it!

@Sparcie2 Well, anyway, that will do it for today. I'll take one final pic as I very lazily sit in my recliner in the back of the room šŸ˜‚. This PC is about 40% tested, and I might just let it run over night and go to bed 😓. Thx for following along!
