hello, what's hidden refresh and slow refresh on bios settings, and what does they exactly do? I have an asus VLI 486sv2gx4 rev 1.7 with an intel dx4 which i plan to overclock, but i dont know if these settings are crucial for that, any suggestion?

thanks in advance guys

lo-fi fingers...

Hidden refresh is a method to do a refresh cycle as part of normal access cycle to a DRAM chip rather than needing a dedicated refresh cycle which will be slower, it helps to increase memory bandwidth. All 72pin SIMMs support hidden refresh and most 30pin SIMMs should too, at least 1MB and bigger ones.
Slow refresh is extending the time period between refresh operations to reduce bandwidth needed on refreshing the memory to increase performance. Data corruption can happen if the memory cannot handle it, you will have to experimentally verify that things are stable.
