Thank You (:

Let us know if the cache on your board is real or fake.

I can feel the smell of those "cache chips" all the way from here... no way those are real.

But as long as the traces are connected to the chipset it should be possible to install sockets and real cache chips.

Looks like the north bridge has bent legs on the side facing the cache chips.

...and JP47 is wired in a way that makes BIOS report "256K cache" at the POST summary screen.

I'm 14 what is fake cache?

How do I know? What is the difference?

I will take a screen shot boot up picture.

Those DCA chips on you motherboard are supposed to be the cache. Cache is a little bit of faster memory that allows faster execution of programs.

Several times before mainboards have been made that reported to have cache, yet in reality the chips where either fake, as in they looked like chips but there was nothing inside of them and the bios was programmed to report an amount of cache.
One of the two retroweb links reports that your motherboard might be one of those with fake chips.

There are programs available on the internet which allow you to verify that they are real or just placebos.
Cachechk is one of those and can be found in the archive available here -> https://www.philscomputerlab.com/dos-benchmark-pack.html
Another option is the use of the speedsys benchmark.

Just don't worry too much about it if (when) the cache turns out to be fake.

The motherboard works just fine without cache and those Octek boards with the "DCA" (Direct Cache Architecture) label are usually speedy enough even though they lack cache.

Octek sold special (and very expensive) memory modules that somehow improved the latency and that's how they got away with labeling their cache less motherboards as boards with Direct Cache Architecture. I do not really know why they bothered with the fake cache chips but I guess those were targeted at another audience than those who read their marketing. Or perhaps more likely they sold the same board with actual real cache on some markets.
