I have attached some screen shots of SpeedSys and Cachechk.
[NOTE: filenames of the first and second cachechk image are slipped. I can't seem to correct it -- perhaps some bug with this forum's software.]
The measured cpu clock speed from Cachechk 4 does not agree well with that of Cachechk 7. Cachechk 4 reports the correct speed at ~120 Mhz, whereas Cachechk 7 reports it as ~107 Mhz. Both agree well on the L1/L2/RAM speeds though. Has anyone else noted this with Cyrix cpus?
SpeedSys reports the cpu speed at 109 Mhz. I suspect the speed discrepancies are due to some kind of software timing algorithm used to measure the speed. I've run a dozen bench utilities, some say 89 Mhz, some say 120 Mhz, 107 Mhz, 109 Mhz. This occurrence is not isolated to this particular motherboard/cpu combination. Identical hardware on my Biostar MB-8433UUD ver. 3 shows similar cpu clock reporting conflicts. Nonetheless, the data from the actual tests is what is important.
For the poster of the AMD 200 Mhz cpu, could you also include the sub-screen on the memory speed tests, its option M on SpeedSys. I would be very interested if you can stably run Windows NT 4.0 on that system.
I get a 3dBench score of 76.9 frames/second. I am not sure if this is good or bad. I do not play games.
I use this computer as my daily E-mail machine, web browser (IE6, Opera8.5, and Firefox2), mp3 player, MS Office, LAN server and HTTP server. Several of the nexgen enhancements will need to be enabled if your motherboard doesn't natively enable them. For example, enabling Fast FPU Exception Handling reduced cpu consumption by 15% when playing unreduced 128kbit mp3s in Winamp 2.85 with the waveout Outout (best not to use DirectSound output on a 486 as it is much more cpu hungry). The FPU in the Cyrix 5x86 with enhancements on is about that of the Pentium Overdrive 83. That was really the only advantage in the iPOD-83. Have you compared your AMD 200 Mhz with the FPU of the iPOD83? That would be an interesting showdown.
