Yes, reflowing is in order. Wanted to get some feedback before i start baking the PCB in case i am missing non-physically invasive options.

local storage devices not recognized on a 386 motherboard

I have this 386 motherboard that is in pristine physical condition. Everything seems to be all right with it except that no local storage devices (HDDs, CF cards) get recognized. I am using trusted components that work just fine in all other cases. Tried few different BIOSes from working mobos with …

Doh. You are right. Sorry. So all good there. LW3D can easily be influenced by win98 vs 3.11/95 that i usually test 486 hardware.

Here is what i meant. In your last post you reported Quake 1 reaching 18 fps which indicates great overall system performance. But the 3DS and LW3D results are 150 and 1454 seconds. They should be around 110 and 1290. This is what i found contradicting.

@riplin Assuming you are talking about that Asus PVI rig: The two motherboards use the same chipset stepping, so it could be a BIOS issue you are facing. There are multiple BIOS versions of the Soyo board - it is a mess really. Not sure which one you are using, but you can use the Asus PVI BIOS as a …

Try these: Filename 20230528_212500.jpg File size 704.17 KiB Views 161 views 64Mb 60ns FPM. Overclock well. Work fine with the SiS chipset version on the Soyo board. (both sides look identical)

I would simply remove it. No point to be there in the first place given the presence of PGA132 socket.

Nice. Some of the results seems to be contradicting each other. For example: 18 fps in Quake 1 suggests well optimized system, but the 3DS test suggests otherwise. Both of them lean heavily on the FPU. Wonder if a different VGA BIOS will help the DOS pixel pushing (Wolf3D, Doom) ? You probably saw …

Wouldn't option B cause the CPU to still draw electric power ? Asking because recently was affected by less than ideal 5V rail issues. Do you know ?

Synthetic tests are mostly meaningless, but if 3DMark is inline with the expectations, then it can be a Q3 specific issue of some sort. Maybe test with few more games/apps and compare results with known measurements. Just thinking out loud here. Hope you figure it out. Things are shaping up pretty …

These numbers are unusually low. Something is not right. With Q2Pro + Vanilla Q3A SMP you should be around 200 fps in Quake 3 (1024x768, highest settings). Or can be the motherboard (BIOS microcodes, etc) that is not ideal ? SuperMicro server boards are not very fast in general, focus is on …

Updated my post with the ISA bus frequencies. I use 50ns rated RAM chips (4x4Mb modules) that work well under much more extreme conditions. The problem is not the memory itself, but the motherboard. Simple DOS tests/apps/games work fine at 2 wait states, but the system is not fully stable and the …

Not into games ? A dangerous statement. Kidding aside - i relate to what you said. Recognized early that making is more rewarding than consuming, so the playing part was short.

Hey, that’s great. Thanks. Will try soon. Did you do other preliminary tests ? Anything out of ordinary ? Will link you from the other thread.

Voodoo graphics cards are mostly outside my areas of interest, so never tried actually. The “coolest” Voodoo card i have is V3 3000 PCI, can give it a try if you want, but you should ask in the video forum or point some of the Voodoo fans to this thread - good chance they will be able to clarify.

No idea about the V cards. Just wanted to comment that the built-in multi-cpu support always worked for me. But i stay on NT4. Story can be different in XP.
