Cyrix 5x86 120 Comments:
This system is stable and fast. I have never had it crash. If i tighten the DRAM wait states any further and take them to 0 the PC will not POST and I have to Jumper JP30 and clear CMOS to boot.
This system has successfully run 5 passes in Memtest86 v4.0 + loads himem.sys without issue and has had hours of testing in Doom, Heretic, Duke3d, Hexen and Quake.
The UM8810P-AIO motherboard along with a Matrox Millenium/Mystique video card appears to be a solid choice for a Cyrix 5x86 based system.
Cyrix 5x86 133 Comments:
This system is extremely fast. Windows 98 is very responsive and It's easy to forget your using a Socket 3 system.
The SCSI interface really makes testing between these two systems unfair as it completely blows away the other systems IDE interface for load time on almost every piece of software tested.
This PC has successfully run 10 passes in Memtest86 4.0 + loads himem.sys without issue and has been tested extensively in Doom, Heretic, Duke3d, Hexen, CPUBURN, Prime95 and Quake.
Since making some minor adjustments I have had the system crash a few times while playing Hexen today 🙁
I'll continue to try and ID this problem
