Hey, I have a Forex 386 board too. It came with 20Mb RAM so it should be pretty sweet, alas, it is very unstable, and freezes continuously during various tasks (running linux, freebsd, qnx, and most other stuff too). Tried every possible bus clock setting. Memtest is okay. Interesting. Might put …

If so, I might have to whack in a SATA controller card. I think that Mau1wurf1977 had little or no dramas setting one up in his rig according to his YouTube vids. Yea they work really well! Just keep in mind to stay with a single 30GB FAT32 partition to avoid any issues. You have to partition it …

Another day, another motherboard. Tested this board with a set of 8x1MB 70ns memory and 256KB 15ns Cache. It's not as fast as the FX-3000 motherboard, but also no slouch. The jumpers are all labelled which makes life easy. Motherboard on Jason.org: http://stason.org/TULARC/pc/motherboards/F/FOREX- …

I'm currently playing with another board. Also I'm kinda in the wrong thread 😀 I will update it in the FX-3000 thread when I get to it 😁

The frequency gets halved from 80 to 40 MHz. So it runs at 40 / 6 = 6.7 MHz. But it is set to Auto Configure, so not sure what it actually runs at :) I tried 40/4 and that worked fine and gave me an even better score. I don't think it's 80/4 because the cards simply wouldn't work anymore. I have no …

ISA controller cards - Winbond not working

Hi all! Got a bunch of ISA controller cards and encountering something weird. The GoldStar (5 cards) and UMC (2 cards) cards all work, but NONE of the Winbond cards. Now this is odd and likely I'm missing something obvious, maybe a jumper setting but I couldn't find these cards on Jason.org or …

what scores do you get for the doom timedemo? I will find out! Currently busy playing around with the SX-33 board. I replaced the battery, quite proud of myself considering I'm not good when it comes to repairing stuff. Video in the process :) I don't have any 30pin 60ns SIMMs, just 72pin. But I …
Re: Best VLB motherboard for AMD 5x86?
Posted on 2013-12-03, 04:34
The other option is to just stick with an IntelDX4. They are also available as 5V Overdrive chips. BIOS support and motherboard compatibility is quite a bit better. In terms of performance you aren't missing out much because the Intel is slightly faster clock for clock. On my Biostar MB-8433UUD-A I …

Why is that battery still on the board? 🤣 De-solder it. Clean it with vinegar and then assess the damage with a magnifying glass.
