I accidentally cracked the core of my Athlon XP-M a few years ago. 🙁 I don't miss the bare die days. I still have a Athlon XP 1800+ (palomino), an Athlon 900 (thunderbird) and a Duron 800 (spitfire) around though.

What the heck, my post disappeared. well my first home pc was a p2 system wich we had upgraded. The computer guy said the mobo couldn't handle the p2 so it was under clocked from like 400 to like 333 it had xp and probably 384mb ram. Not till 06 did i get something decent wich was 1.8 ghz socket 939 …

But I knew a few people who went from something like a PII 266 or K6-2 to a Duron 650 or so and it really blew their minds. Not only is a Duron/Athlon CPU vastly superior to any K6 (particularly for games), but so is the entire system platform, and it really added up. It was fun to see that. I went …

This is unfortunate - I can't successfully boot up the mobo, because the CMOS battery inside the Odin RTC block is dead. When the mobo displays its BIOS POST messages, it says that the CMOS battery is dead. I did a search for OEC12C887A (seen on the RTC in the photo) on ebay, and I can find one …

After some googling I've come to the conclusion that this ODIN chip is the same as the DALLAS DS12887 I recommend buying them from www.futurlec.com, have bought some of these evil chips in the past and their service has been excellent

OK thanks a lot! I'll get one or two, and then continue my testing on this board... I had a look at the BIOS options, and there is something called "Host clock / PCI clock". Is that something which is useful? The mobo's BIOS datestamp on the BIOS POST screen says March '96, so it's quite "modern". : …

Before buying a dallas chip, why don't you try to hack yours? I've done it twice, and both chips worked fine. Here's the RTC chip I fixed yesterday on a 386 motherboard, which was useless before. Uploaded with ImageShack.us

Believe me, the hardest part is to "cut" the plastic, where you need to find the connectors... Most motherboards I've seen use the DS12887. But that particular 386, when I desoldered the chip, it had DS1287 written underneath. I don't know what difference a number(8) can make, but 2 spare 12887 I …

I have got this mobo working well. Tweaking its BIOS settings to the max, I get 83.3 in 3DBench, using a 1MB PCI Trio64V+ card. That's using a 5x86 P75 chip, running at its native speed of 133 MHz. I'm using 1 stick of 16MB EDO RAM.

I ran Doom shareware 1.9s, and set the screen to full size. I then ran doom -timedemo demo3, and I get 2134 / 1667. I ran Quake shareware 1.06, and set the screen to default, which is "2 notches" below full size. I then ran quake timedemo at the command console, and I get 14.2 FPS. I wonder if my …

That's quite good performance actually. Perhaps you would see 1 or 2 more frames you used something like a Matrox, but it really doesn't make much of a difference does it? If you add more RAM you'll get less swapping, because the system deletes bytes from RAM much less frequently.

Very pretty motherboard. Did you check bios settings stability under Win95? I love 486 boards based on UMC chipset. I think those are the best! (:

That is really magic jumper, especially during finding undocumented FSB settings. (;

Thanks a lot for the info, people. I haven't got a W95 HDD at the moment, but I have got W98 and also Wme. I'll try them as soon as possble. Also, I will try to find some undocumented bus speed settings. I'll see if I can get all of this done today. I've already increased the RAM from 16MB to 32MB, …
