Re: 486dx/2 100MHz Test

Yes fully agreed. I did all that. And at the end it works but very unstable w/ L2. Without seems ok. Anyway the benchmark results were so close to the dx/2 80 with highest speed settings that I was really surprised. The synthetic mem and l2 benches of course even lower. So at the end no need to go …

Re: 486dx/2 100MHz Test

Sorry just saw that below the die there is nothing and the heartsink i won’t remove right now CTCM reports CPUID: Cx486??/ Typ:00 fam:04 mod:00 step:00 FPU i487 type L1 Cache 8KB 4-way WT Version 1.5. Update: system runs so far at 3,4V Update: System quite stable w/ 3,6V. But only with L2 disabled. …

Re: 486dx/2 100MHz Test

Sorry for my misunderstanding. Thanks so I will provide cpu and ctcm Data later and check again all correct jumpers. My board supports cpu voltage selection 3.3/5V by >2 jumpers thus there might be hidden non documented settings behind. But that’s for Phase 2 maybe :) Besides NW I don’t have any …

Re: 486dx/2 100MHz Test

Yes I will now ensure that I choose the right cpu type plus voltage and test it. Only using one vlc gpu trident tgui9440. Remember the Limitation could also come from my 486dx/2 66 cpu itself. But now a bit confused. Should I overclock the CPU voltage to 5V or not? Seems quiteeeee a lot from 3,3v ;) …

486dx/2 100MHz Test

Im Running an amd486dx/2 66 on my chicony 471b MB rocket stable at dx2/80. Then I thought let’s try 50x2. Said done. System unstable but enough for some dos benchmarks. Disappointing mainly due to low mem settings I had to set. Interestingly Bios posts Am486DX4100 :) I also tried this one with a …
