but does performance improve too? your cache seems a tad bit slow, so maybe settings are wrong?

if i disable L2 cache, system is slower. i followed the manual informations
i even swapped cache ram (not the two cache tag srams) 15ns without
improvement

so everything is generally ok, just look at the settings; i dont remember the numbers but i do believe l2 might run faster

a lot faster? what should i expect ? maybe i am wrong and everything is ok

see an example - imho this looks similar to yours - https://socket3.files.wordpress.com/2016/11/speedsys-486.png
just find cache settings in bios and check them;
the speedup will not be huge anyway - to be specific - by a quick google i found one example where l2 did 50MBps

thank you very much !
