If you make a category for ISA Bus, VLB bus and PCI motherboards then I can enter my computer benchmarks for each motherboard type.

The Intel Chipset motherboard I am using has a Turbo button but it does not seem to work. So I just disable cache in bios and with SetMul utility. With the AMD K5-100 running at 75mhz I have been able to slow down the CPU to fast 286 levels. Maybe 40mhz. I am not sure. But it is definitely slower …

Or get a Pentium 90, which will do 75 MHz (25 x 3), 90 MHz (30 x 3), and 100 MHz (33 x 3) with no issues. Running a P75 at 100 MHz is quite a stretch and most likely not reliable. No, let me re-phrase this. I want to use one CPU. I just want to be able to down clock it to 268@10mhz speed. I want …

I got a couple Pentium MMX 75mhz CPU’s for my Ultimate DOS gaming computer test build. I found the 486dx4-100 too slow for NEWER DOS games so I am experimenting with the Pentium CPU now. I want to find the sweet spot between the CPU speeds of the 286-10mhz thru Pentium class CPU. Using just ONE …

Yeah, I am going to put the Pentium on this Intel Motherboard and the K6 on the Via chipset motherboard. Then I will compare performance at various speeds.

I doubt you would be able to achieve this level of performance (or lack thereof) with a Pentium-class CPU. But for all means try something that runs at 50 MHz FSB. You can actually jumper your Pentium 100 (66x1.5) to run at 75 MHz (50x1.5). My feeling is that it would run roughly as fast as 386 SX- …

Yes, that is a really nice computer. A dream build for some back in 1993/94. It would have cost allot of money back then about $5000. But still would not have meet your expectations as modern DOS games play better on a Pentium CPU. That is my primary to have a good computer for playing DOS games as …

I am doing just the opposite. I am starting with a Pentium and seeing how slow I can clock it down to. Currently I am using this setup with an AMD K5-100mhz CPU. By disabling all the caches on the CPU and Motherboard I have been able to slow it down to a 386@40mhz. My goal is to take a Pentium CPU …

Fixed. I added an CF card reader to this build and the CF card was causing it to hang. I used the tool “Clearhdd” to setup the CF card and it worked fine after that.

I am currently testing an AMD K5-100 CPU build because I found the 486dx4-100 just to inadequate for playing modern DOS games. By disabling the CPU caches I have been able to slow the K5 down to a 386dx@40mhz. My goal is to go as slow as a 286@10 mhz which I was able to do with my 486dx4-100 CPU. …

Okay right now I am testing this Motherboard with the AMD K5-100 CPU. By disabling CPU internal and external cache I have been able to slow down the CPU to a 386dx@40mhz. I want to be able to go as slow as a 286@10mhz. So I guess I will have to try a slower speed CPU. What do you recommend ?
