I just had a thought, since it's looking like running beyond 200MHz is slim... has anyone had any success running at a 66MHz bus w/ 1/2 PCI divider? Even 66MHz x 2? Which RAM and cache are you using to achieve a stable 66MHz bus? AMD x5-133's only have 3x and 4x operation, so personally I cannot …

Very nice history! Funny how you went from a 633Mhz -> 2Ghz... night-and-day I'm sure! I started with an IBM PCjr that my grandmother gave me in 1992 (I was 8 ). I tore it down, cleaned it out, and had all the pieces on my parents dining room table. Needless to say my mother freaked out because I …

I'm having a hard time getting both UNIFLASH and AWDFLASH to run in DOS... I hear it begin to load, then just stops, cursor blinking on the screen. Anyone experience this before? I can't see why these programs are refusing to load. I'm trying DOS 6.22 and pressing CTRL during Win98 boot (DOS 7.1)... …

@ feipoa, you're playing Q2 with no sound? I found that only gives me .5-1.0fps on average, so I kept it. Yeah, I'll give the L2 cache a shot... even at grandma timings... 😵

What motherboard are you trying to plug everything into? If we can get a picture of the board, or a schematic, I'm sure we can point ya in the right direction on what-to-plug-into-where.

Well, the full version of Q2 came in. :evil: FWIW, with all the tweaks in the Q2 book (in OpenGL basically everything is off) I received: OpenGL demo1 640x480: 10.2fps SW demo1 640x480: 4.9fps OpenGL demo2 640x480: 10.5fps SW demo2 640x480: 4.8fps This is my baseq2\autoexec.cfg to get the 10fps+: …

Have fun guys, I'm going to have to revisit this - Quake 2 will be at my door later this week. @feipoa - no, I'm sure I can run @ 640x480, but something is buggered with this demo. I'll try it regardless and I'll post the results. It's just that not being able to optimize the config is a real PITA. …

Wish I could test it that way, as I've put a good 4 hours into troubleshooting, no luck. All I have is the Q2 demo and any change to the config.cfg, it crashes on load. If I create an autoexec.cfg it doesn't load it. Pressing ~ and typing "exec autoexec.cfg" it says it couldn't load it.... lol I've …

Well, now with the battery replaced, the 8433UUD board I have is much more stable than the M919, so I'm using that now. Setup is: AMD 5x86 @ 180Mhz (60Mhz x 3), disabled L2, 0/0WS 64MB DRAM (I found 1 stick to be more stable than 2) Fresh install of Win98se, DX 7.0, Diamond TNT Drivers (yet to find …

TBH I'd even say an Intel DX4/100, Cyrix 4/586 100-133, and AMD 4/586 100-133 were even more common than the Pentiums then (and IMO were more fun to mess around with). Most of those CPU's were equivalent to Pentium 60-75's, not overclocked, if that's the particular speed you're after. EDIT: However, …

For my interests, the benchmark results are not of interest until the system is demonstrated stable. While I can respect where you're coming from, I disagree. A benchmark is exactly that. Many of the best 3DMark systems in the world are only stable long enough to run 3DMark, usually due to thermal …

The latest version I tried is 8.05, the earliest I tried is 5.22. It isn't stable though, IMO, not even enough to run some benchmarks. However, the driver properties themselves are fantastic.

Well my 8433UUD board is dead (RTC), so I swapped it's BIOS with the M919. MUCH better BIOS! (I forget how awesome it was). So as of now I'm using the M919 w/ the 8433 AWARD BIOS, not the AMI. It's actually quite stable and feels faster... preliminary benchies! AM5x86 @ 60Mhz bus, 3x multi, ~187Mhz, …

What if am5x86 works fine at higher frequencies but is just sensitive to higher bus speeds? Without an interposer it is not possible to test this theory unfortunately. Are there any socket3 boards that have a 1/2 FSB to PCI divider? If so that would help a ton. I know what you're saying regarding …
