I have two of these boards, a 1.04 and a 1.06
I would like to use the 1.06 more often but I keep preferring the 1.04 because it has 1mb cache.
What chips do I need for the 1.06?
How much of the 1.04 can I use as reference? And is 2mb (or more) possible if I get the right tag chip?
I have never read that 2 MiB L2 cache are possible on Aladdin V and I think it's useless. 1 MiB + external TAG + internal TAG gives you a cacheable area of 4 GiB. There is no motherboard that can be equipped with such an huge RAM capacity.
You need these chips and some resistors:

I ordered them from a supplier in Hong Kong directly last year.
I used them here for my Jetway 542C. I will post an updated electrical diagram soon.
Your Rev 1.04 board has also only 512 kiB L2 cache.
Do you have a flatbed scanner? Would you make a high resolution scan of your P5A Rev 1.04 and 1.06? You can use mainboard spacers to position it on the scanner.

Can I upgrade the tag chip to more bits?
I don't think so. When you take a look at may DFI K6XV3+/66, you see it has 2 MiB L2 cache and a 10bit TagRAM. The Tag has 32 pins whereas your board offers only 28 pads for soldering of a TagRAM.
I don’t have a scanner.
Sweet! So those are the part numbers of the best chips that will fit this board (in the pic)?
What areas do you want to see? I can take good pics of them or the whole board from afar. My phone is high res so you can see whatever you want probably in the pics
Crap, hold up, edit:
You know what,
On this board it skipps past the screen where you see the cache size so quick and I was distracted trying to figure out the stability issues, memtest doesn’t show l3 size and whenever I started cpu-z I was overclocked with cache disabled that I guess I just assumed that having a tag chip and meant that it had 1024k but I was wrong. I’m sorry, both of these boards are actually 512k
Well, mark that down as even more motivation
