I'm going to do another roundup but at 250mhz, with a mvp3 motherboard with wider voltage support, if anyone is interested. I have come concern about the chance to overclock some cpus, so I'd like your opinions: The cyrix higher voltage i'm going to use is this one: https://cdn.cpu-world.com/CPUs/ …

There is not much to say, it's a cyrix rebranded, usually ibm cpus were a little more overclockable compared to cyrix ones but that's the only difference.

You might try testing it as a ST M48T128V which is another DIP32 128kx8 cmos SRAM with nearly identical pinout (except missing the second CE, has that pin listed as NC), the software may not like that choice but it would be worth a try. A few of my oddball cache chips I used a specific other choice …

Sorry for the necropost. I'm messing around with this mb. Apparently it doesn't like to work with 1024kb of cache, it makes up to the post screen but then it hangs, I was able to make it work with 512kb (128K x 8 ) with 128k as tag, chinese IS61C1024-10N.

Thank you for the tip. I noticed that even if they complete the test successfully, but when put on the mb the cache chip isn't detected (when a faulty chip is on it says no cache, while with a working chip it gets detected fine). Can you please elaborate the adapter part? How should it be done?

I just received a bunch of l2 cache (IS61C1024-10N), as always some of them aren't working, I remember that the TL866 allows to try the sram chips but I can't find the right options, apparently the max supported is 512? There are several brands and a Standard SRAM list, but it lacks the Integrated …

Yes the system is oc, but the pci express bus is locked at 100 or 101 mhz, also as posted before, I tried to load the default setting, so undone the overclock but it didn't help.
