I changed L2 cache to AUTO and the results in games jumped up considerably...Cachechk scores now normal (compared to 486 Benchmark scores): Auto probably set the correct dirty bit (7+1), which you otherwise do not have manual control over. If the system has it set to 8+0 for WB cache, I too get …

The document Cyrix Register Enhancements Revealed would have been able to answer your questions on this. There is a chart on page two which lists out typical default settings on the Cyrix 5x86. These are default on most motherboards, USE_SUSP, WT1, LOCK_NW, USE_WBAK, DET_E, MEM_BYP = 1. The document …

I am currently playing with a SiS board. I have witnessed this funny RAM speed slow down if the L2 cache is set to write-back mode and if the TAG is set to 8-bit. Did you put your L2 cache onto write-through mode? If that doesn't fix it, try putting 256 KB cache back and jumper the board for 256 KB …

A well configured AMD X5-150 should be faster than a Cyrix 5x86-100. If the L2 and RAM timings need to be dropped too low, then I suppose the Cyrix 5x86-100 could be faster. The Speedsys score is not necessarily indicitive of real world performance. Are you using 'cachechk -d -t6' to check your …

Meaning, a system configured with the maximum amount of L2 cache possible, memory possible, best graphics card within the reasonable limit of a user who still might have still upgraded, best CPU of an era, such as a 5x86-133/4x being the best production socket 3 CPU. Best Socket 7-GXM Cyrix …

Does anyone have any framerate comparisons for identical hardware in Win98SE vs. Win95 OSR2.x for 486 through Pentium 133 systems? I am wondering if the bloat of Win98SE cuts in to framerates at all.

The unofficial Win88SE service pack is everywhere online. It is even on those annoying download sights which have 10 "download" buttons, whereby you need to figure out which download button is the correct one. I think an AMD X5-150 is faster than a Cyrix 5x86 at 100 MHz. Are you using a VLB/ISA-only …

I've noticed the memory read speed to be really slow like this when the dirty bit is not set appropriately in write-back mode. Try setting your L2 cache to write-through mode and run cachechk again. I suspect this will give a proper speed reading. Are you able to pass MemTest86 4.00 with L2 in write …

Maybe VLB/ISA-only boards were designed with 40 MHz operation as a primary objective? Which chipset is on that board? I wonder if POD-100/40 cache/dram timings are naturally less sensitive than Cyrix 586-120/40 timings...? Your BIOS is missing one of the cache options in some SiS 496/497 chipsets I …

Ill do some reading and testing and get back to you. Why do you use Windows 98 to test your cpu is stable and not Windows 95 C? Everything runs a little slower on Win98 compared to Win95. The slower the OS, the higher the CPU strain. I find that Win98 is forgiving on some stability issues, so NT4.0 …

Vetz, I think you noted some of my benchmark scores incorrectly. For the POD100, it should be: L1 / L2 / RAM 195 / 56 / 44 L2 is at 56 MB/s. What L2 and DRAM timings are you using with your 1024K VLB board? I've noticed recently on a SiS 1024K board that the timings need to be reduced at 40 MHz …

Perhaps. But, I have two -100HF units. One of them overclocks to 133 MHz at a low lower voltage the the other. One needed 4.0V, which makes it run too hot, while the other did pretty well at 3.75 V. To be honest, I only used a generic 486 heatsink/fan on the -100GF unit, so I cannot really comment …

Is there a difference between a 100HF and a 100GF? The biggest difference I can see is that the HF has a heatsink attached and the GF doesn't. That is the main difference I noted as well, however in my actual tests, I found the -HF models to overclock to 133 MHz quite a bit better. It may have just …
