To me the SX955 is the ultimate DX2-66. I've got three of them. They all do run fine art 3,3v and without fan they keep cool to the touch. WB does require bios support. If the bios does not explicitly support it, chances are high the CPU runs WT (nothing wrong with that, runs just fine, but a waste …

I have one SX807 that is "SL" version but not WB, instead SX955 is "SL" and also WB. So it is the one to have? Hi AlessandroB, Just a side note, but I had a recent interesting experience with those two DX2-66 variants. I upgraded a small 486 system board with the SX807 and all worked normally, I …

I have a 486 with a vlb slot, as a cpu I have intelDX4, POD83, Cyrix 5x86 100. I noticed that Doom does not use the pentium instructions much so the POD83 is not used, but it doesn't matter, the DX4 is more than decent. Things are different with Screamer. Here the POD makes the difference and …

Probably 1998-2002 stuff - at best. I'd settle for 2000 minimum for true period gaming though, p4 1.5's indicative of someone duped by the big marketing, ignoring the big disappointment, and going to play the can't-possibly-be-disappointing Tribes 2, Red Faction, Black & White, everything on …

You could cover those last few dos games that don't like your 486 if you use a compatible PCI card but it'll be a compromised experience. Where as a P4 has enough power to run dosbox and play those same games somewhat ironically. What will limit you next is the graphics card. You can either get say …

It runs fine if you have a good build with a fast Video card. It can get a little laggy though. "little laggy" is what you could say in 2000. With fastdoom you have actual fps meter and there is no need for subjective adjectives :) 36fps at 50MHz with late Trident VLB card https://www.youtube.com/ …

I not able to modify the integrated voltage converter, and honestly I don't want to change this piece of computer history. There is no other way right? i thought if it was really unstable it couldn't pass the speedsys test
