Well, only if you consider a 286 to be useless.

Last time I tried disabling cache in my 300Mhz P2, it made even using a dir command in dos a slide show. If I turn turbo off and disable L1 and L2 caches in my 486 33Mhz which is about same speed as 286 6Mhz based on benchmarks, it was much more usable in dos than my P2 with cache disabled. If others have had different experience, it could be that something else was wrong with my P2 system.

That sounds a bit slower than typical. Interesting.

On my 486, which has a DX4-100 OverDrive installed, I have bat files that load the cacheoff and cacheon commands that I made using the MS-DOS Debug program and it makes my system run as a 386SX (or DX) 33, maybe a bit lower. I will check that with another program to see what the speed actually is.

When I disable the L1 and L2 cache on my Socket 370 board, it ran as an 8088 4.7MHz, whereas my K6-2/300 ran at 20MHz or so.

I have an AT board that might have potential for this. If you could do a bit of reading here, https://www.tomshardware.com/reviews/600-mhz- … et-7,210-4.html, tell me what you think about it. I may get back into it and try some things out myself , if i get time.
