Okay, I see. It's still interesting to see cache breakdowns where applicable. Thanks. You perhaps are able to save the chart with SpeedSys' save function. It will generate a .pcx file which can be converted to .png and a .txt file too where I can see the abysmal performance in detail then :) Sure! …

j^aws , these (s)s.7 motherboards with "turbo" switch functionality are not so common. I see that for some of your test results table you've manually disabled L1, L2 and L3 caches and switched to "de-turbo" mode for even slower CPU speed. Does this mean that the "turbo" switch in "de-turbo" mode …

Wondering if this could be done to reach the "sweet spot" for old games requiring 286'es and such (reason for the turbo button) Yes, indeed this does occur with the range of speeds available. Something to also consider is the VGA speed where animations can be too fast still, even with the correct …

Are there any bugs in editing and submitting posts on the forum where you get double posts? I'm thinking if you don't 'preview' the edit before posting, a new post happens rather than an edit? May need to test this and keep an eye out as I had a triple post when editing and submitting earlier. …

Impressive chart. Yes but SpeedSys shows now 9.26 and not the 0.45 from above. Has this low value not been reproduceable? Yes, it's reproducible - the test just takes a very long time to complete. The 0.45 Speedsys is with all caches disabled (L1, L2 and L3), so there isn't a cache graph from …

Speedsys Please may you post the cache chart of SpeedSys? (You can skip extended memory test of course) Sure, luckily managed to grab these at the time: K6-III+ at 100MHz with Turbo enabled: 100mhzturbo.JPG K6-III+ at 100MHz with De-Turbo enabled: 100mhzdeturbo.JPG Wow! Very nice! Thanks!

Still waiting for someone to hit 7mhz core clock on socket 5/7 I tested this configuration a long time ago, even slower than 7MHz using Socket 7 board with working Turbo header on a K6-III+, slower than an IBM XT, measured using various benchmarks: https://www.vogons.org/viewtopic.php?t=53479 …

Hello! I understand that I am writing quite late, but maybe you still remember. What is your motherboard for this K6-iii+? And maybe you remember what clocker was on it? (chip) I make the assembly on the GA-5AA and, unfortunately, the minimum is that I can do 60MHz, and the maximum that I can …

Could you please share how you do this, meaning what tool, what commands? This could be of interest for "slow down" projects and helpful in getting old games to work a bit better :) I don't think I've come across a software tool that does this, but maybe one exists and is lost in time...?

Thanks! So did you compile any list of compatible games, cause I cannot find it if so, maybe on another thread ? It is actually easier to make a list of *in*-compatible, which consists of this: - Quarantine The system I used in the OP is very flexible with CPU slowdown (VIA Ezra-T); besides …

... Guys, what's borderline for you? Or maybe you are still excited with new computers and the charm is still here? The 'PC' was never soulless. Biggest thing to happen to the original IBM PC standard was the cloning of it by Compaq et al that opened up a flexible 'open' standard for its hardware. …

For slowdown machines, you can pair slow ISA VGA cards with fast PCI cards in the same machine; much like using slow PCI cards with fast AGP cards in the same machine. With a slow ISA VGA card matched to a 'slowed' down fast CPU, you can get appropriate speeds in speed-sensitive games where certain …

I think this is a mistake. The NV18 is the GeForce 4 MX 440 AGP x8. The NV18C is the MX 4000. Also, the defining factor between the FX 5200 and the 5600 isn't the clock speed but rather the lack of color and Z compression. This was a terrible bastardization in the name of product segmentation. The …
