Don't you need a Dirty RAM in the 22-pin socket next to the tag RAM? Maybe you can temporarily set up a jumper wire to do an "always dirty" configuration just to get it working?

Ah, what exactly should I search for to obtain whatever you have mentioned?

Hey everyone, I have been attempting to get the L2 cache to work as I have installed it in the correct orientation and know that these chips have been tested to work. I went to turn off the cmos battery for ten minutes, played around with the jumper settings. I am clueless how to remedy this.

The cache in question is 256k L2 sram

Hello,

I never heard of "MAGIC" 64kx8 sram chips. Are you sure these are not fake?
Where did you test those chips?

EDIT:
I found a reference here:
LS486e trouble booting with L2 cache on(2x66)
so I might be wrong.
Seem to be rare though. I don't know.

MORE EDIT:
I read that you have a lot of 32kx8 sram chips.
If yes, remove those Magic chips, and put 4 times 32kx8 inside instead in order to check if 128kB is working correctly!

I have received the dip22 chip. Once Installed it next to the tag ram, the cache was detected and shows 128k. Man does the computer feel quite a bit faster and more responsive.

So you did remove those "Magic" chips? And put back the 32kx8 chips?

Nope. The cache check tool does not even tell me they are fake. It says it detected l1 and l2 cache so it is real cache.
