Slot-1 is also an L2 cache module. They just added the CPU on there for convenience :) I mean, technically, you could say that. What about when it gets to the Coppermines? I've went ahead and put a little dab (BB size or so) right where the die would be, and pushed it down. Seeing as ~75% of the …

My Pentium board has a COAST module for L2 cache: https://en.wikipedia.org/wiki/Cache_on_a_stick So that's what some of those Socket 7 boards with the Slot-1 knockoff connectors use. :lol: I always was confused as to why it was there, because I knew they couldn't take Slot 1 CPU's, but this …

Sorry I vanished for a bit. Thought I overreacted to me being wrong, but I guess I didn't, anyways, I wanted to take some space for a bit in case I had overreacted. Anyways, the lack of L2 is something I feel like I should've known in the first place. Why does my motherboard have soldered on L2, if …

I'm a bit confused - ceramic Pentium MMX 200 MHz? :exclamation: I'm pretty sure that only the MMX with 166 MHz was ever available as ceramic. The 200 MHz one had a plastic package. No, it does not. No socket 7 CPU ever had L2 cache, apart from the AMD K6-2+/3. The L2 cache is on the mainboard. Are …

There is no L2 cache in Pentium MMX and the CPU die itself is less than 12x12mm in size. The CPU does have L2 cache, a massive 512KB of it. I know that seems odd for a Pentium MMX, even I was taken aback by the presence of it, let alone the amount, but it's there, according to Intel themselves. …

Just a dab of paste in the center of the CPU will do. Let the presser of the heatsink spread it. a pad? well these CPU's don't make much heat so that might work. That's what I did earlier before I made this post, actually, but I felt like it wasn't enough. The surface area of that CPU has to be as …

Just use a graphene thermal pad :-) I probably would if I had one at the moment, but I don't. All I have right now is some Artic Silver MX-4 that I'll probably put on it when I get home. Right now I have some el-cheapo stuff that the school has, and it probably would be good enough for something …

Better monitors have magnetic shielding cage around the tube so that they are much less sensitive to external fields. Neck area is the most sensitive part since small change there gets amplified dramatically by the deflection later on. These screwdrivers shouldn't cause any sort of pulsations …

I know most ceramic Pentiums didn't use thermal paste at the time- but I'm starting to work on a Pentium MMX 200MHz, and I'd rather play it safe than sorry. The problem I'm having at the moment is a question of how to apply the thermal paste to the CPU. A pea-size dot in the center, more, less? The …

It seems that this was caused by a set of magnetic screwdrivers I was storing somewhat nearby (approx. 1.5ft away from the monitor) in a little plastic organizer. The fact that they could cause something like that never even occurred to me, and bringing them far away (now approx. 10-12ft away, with …

I don't get it, does raster stretch out vertically or horizontally? What have you tried to remedy the issue so far? Better post a video of the fault.

If you don't have any 50/60Hz transformer nearby the rear of the monitor (they create a changing magnetic field that could cause such a jitter) there's likely some electronics problem in it and if capacitor change is as good as dead, all other things involving testing and swapping stuff in it are …

It sounds like blooming, this phenomenon happens on most shadow mask CRTs and is absolutely normal. What happens is that whenever a bright image is displayed, the mask "expands", on some tubes it isn't noticeable on others it is. @Horun You seem to be forgetting that most if not all 4:3 LCDs have a …

The mod looks pretty nice at the first glance, but you sure have more than just a couple things left to do in order for it to be finished properly and completely. OK, lets start from the beginning. 1. I would've discouraged you from cutting the riser board, but the deed has been done. Riser board …

Just as I was heading to install MS-DOS on my 486, I noticed that, with a bright image, at typical "DOS resoultions," (the BIOS screen of the PC, scandisk, etc.) the horizontal edges of the screen move back and forth a couple of millimeters or so, but the center stays solid. The top and bottom edges …

At the moment, I don't have any pictures of the inside of it yet, as I recently moved, and still have yet to get some screwdrivers moved over. All of this work was done at my local technical school with the aid of my instructor, as I've been attending there for a couple of months now and crazy …
