Hello,
I recently purchased a PC Chips M919 on eBay. It arrived yesterday and thankfully it posted right away. It works and is stable and all. There is just one problem. It does not use any of its available L2 cache. At first I tested with my Cyrix 5x86 (which I suspect is a little broken, I think I inserted it the wrong way around in the socket when I was a lot younger anyway) and on POST it only tells me that 64k of cache are detected. I switched to an AMD DX4 NVT8 and now it tells me on POST that 256K cache are detected. All good so far. Problem is neither cachechk nor speedsys detect any L2 cache. I'm baffled on how the board can detect the cache on post but than just not use it. All 9 chips to get warm, so there is at least something happening. If attached some photos of the board, the module and the socket. Dont know if they are good enough, I can try again with my DSLR if necessary. The socket does look a little wierd but I don't know if that could be the problem and I'm not sure on how I could “fix” it.
So if somebody has any ideas or input, please let me know 😀
A little off topic: How hard and expensive would it be to produce new cache modules with some sockets on it (because it would be nice to have another one of those to test with)? There probably wouldn't be a high demand but the prices people ask for this module on eBay is and I can't imagine it would be to costly to produce given how small it is and how little components are used.
Update: The Cyrix started to also "detect" 256K on POST. I guess thats progress.
