Hi,

I’m checking the jumper settings of my “new” asus vl/i-486sv2g mobo and I’m seeing a weird combo of jumpers that shouldn’t be possible to configure the L2 cache settings. (i.e. the combination is not mentioned in the manual) So I need to correct it, but I’m not sure about the capacity of the sram installed.

How do I determine the correct cache size of my sram? I did a search for “ um61256fk-15” and it seems to be 32KB. Is that reliable?

Thanks!

The chip size is normally in the name: um61 256 ak-15. So 256 Kbits / 8 = 32KB. The 15 at the end is the speed.

When doing a sanity check, um61512ak-15 was a suggested search string, those would be 512, so 64KB modules.

Super clear, thanks a lot!
