It will definitely still work with B450+RyZen if someone is curious about the ultimate limits. Although I was lucky with this one, I didn't update the UEFI/BIOS, there may be problems with the newer one. Drivers are solved, there is also a modified patch for the VCache error, but with newer UEFI it …

Was that a 2.2V MII at 2.5 x 100? Because it's odd it didn't score level with the 6x86mx at 2.5x100 otherwise. We've been speculating as to whether the core shrink added some latencies to try to get higher clocks. No, 2.9V black. Back in the day it was Gold for me, but now I was curious about the …

Epox boards of that era rock! I have the Baby AT version of yours but I didn't test the W2 on it. I made a comprehensive S7/SS7 test from 100-617MHz, which is why I used Epox. FSB/multiplier can be practically varied + a video card that didn't even exist back then, I like such extremes. I have the …

Are those 128mb sticks single sided? If not, try that. I’ve noticed that there is a ram size/speed sweet spot at 384 mb of ram single sided three sticks. Technically many mvp3 support 768 256mb double sided x 3 but it is slower than 384. I’ve also noticed mvp3 seems to more stable single sided. …

Any other suggestions? :D I see APU is a 2D card. Maybe something is missing from the system drivers or the installation is incomplete? DX9.0c 2004-2006, which also supports 98. Is there a Win98 driver for the APU? Although if it's ok with 1 card, it should run with 2. I tried it on a more modern …

Do you plan on leaving the labels on the CPUs? The presence of the labels may leave permanent discolouration on the ceramic over the years. I was looking at your Cyrix 5x86-80GP and thought the font was a little off, like the '0' was remarked. This is what my 80 MHz chip looks like next to yours. …

Its not a 7600GS its a 7100GS. Its been a couple of weeks since I was messing about with it... But the idea is the same. Like I said I think its super situational to get Win98 to work properly on a 775 board because most of them dont work properly. S775? By default, the modded X58 drivers are …

The Cyrix 5x86-100 was a pretty common one. The -120 not so much. The -80 is pretty rare though, and yours is in excellent condition too. What kind of interposer is it using? Well, I don't know exactly, I think it's a converter/voltage regulator, I haven't tried it yet, but as you can see in the …
