So I'm dicking around with my SL2C board, using some old cache chips I had to upgrade it. It now had 128k, but none of the actual tag chips I had would recognize it. Out of curiosity, I tried one more of the cache chips, and surprised, it worked, making it read 128k.

SO is there any difference betwee na TAG chip and a cache chip? If not, why are they always labled different?

They are all SRAM chips

I think the main difference is their access time since tag memory is accessed before every cache memory access

I have once remove cache chips from a dead 486 mobo to upgrade some other
Tag chip was rated 15ns and cache 20ns
