I'm asking myself a question for a long time now. Could it be done to use tulip socket to insert caps? Or is something wrong with that. That question came following a thought about having a way to easily replace all components prone to fail on old hardware. I got capacitor who inflate to the point …

@HanJammer. Yep Would means VRC, but for me, except one is embedded, it's the same. But yes, for latter 486 till Pentium Pro, plugable voltage regulation modules was great. I'm asking myself a question for a long time now. Could it be done to use tulip socket to insert caps? Or is something wrong …

Finding a game box in the collection or the right bag of CD, then finding CD in it, then swapping CD when needed is, indeed, a true experience, but not especially the best one. As a kid I had plenty of time, but now, for my retro passion, I often take more time searching for a game than playing it ( …

I think the slowest I had was sold as a 500Mhz but had a 650Mhz core. Back then, most of them had higher rates cores than they were sold as. The ones sold as 650Mhz were often 800 or 850Mhz rated. Pop off the heatspreader plate, check the engravings on the CPU core and then move the 0-ohm resistors …

I just checked because I was not sure but the Athlon 550 MHz is a first gen, not a Thunderbird. My mistake. But it never got very hot. If @cyclone3d says Slot A Athlon are heating up a lot, maybe that is the ones with high frequency. I don't know, never had one.

To remove a capacitor as they pass through the motherboard, beware to not damage the gates (the little cylinder that makes the link between the different layers of the motherboard). I recommend using a desoldering gun. Easy and fast. To remove SMD like the voltage regulators, it require more …

To test a capacitor, it must be removed, yes. I remember Socket A Athlon and Athlon XP are getting hot, that's normal. But as they have no overheating protection they need a good cooling. For Slot A, I don't remember them getting hot. I have an Slot A Athlon 700 MHz in a machine. It have a radiator …

Indeed, can be capacitors. I have two dead "waiting to be repaired" ASUS motherboard of the same era (2000-2003). A A7N8X Deluxe that have a track who literally melt because of a dead cap. And another CUW-AM who got abnormally hot on the CPU area for a few days before stopping to work. It has …
Re: S3 805 color depth mystery
Posted on 2021-09-12, 19:21
It fails due to 640x480x32 (1,228,000 bytes) requiring 2 MB+, 32-bit color are 4 bytes for each pixel. That is what I said previously. But it failed too with 24-bit because it is not supported. So I'm limited to 16-bit on this PC. And that's fine as I want to use it for DOS apps only. But I'll will …

That said, if the card supports 32-bit it haven't enough memory to unlock it. I haven't check the VESA modes supported by the card. I have to see that to be fixed.
Re: S3 805 color depth mystery

AFAIK, early S3 cards only supported 32-bit color (this is more noticeable if you check the list of VESA resolutions, there may be some exceptions) instead of 24-bit and it's actually for performance reasons due to alignment. If the Diamond Stealth24 RAMDAC supports 24-bit color it should appear at …

Hi. I just upgraded the VRAM from 512 KB to 1MB (max supported by the machine) of an HP Vectra 486/25N. That is 4 chips 256x4 60ns embedded + 4 chips 256x4 60ns socketed. The card is an Elsa VLB with a S3 86C805 embedded into the motherboard. The VRAM is fully detected by the BIOS and Windows 95 is …
Re: Can this Pentium 100 motherboard accept Pentium MMX CPU?

So5 and So7 are almost identical. The biggest differences are that So7 supports two multiplier pins (for 1.5x, 2x, 2.5x and 3x) where So5 only has a single one (for 1.5x and 2x), and that So7 optionally supports split voltage - but early So7 boards rarely implement that. Given that a P233MMX …

@SquallStrife First of all. Many thanks for having created this web site. It is very useful. The only real small weakness is that the user manuals are not structured as the drivers are.

The P6 micro-architecture (Pentium II and Pentium III) include information that a voltage regulator IC can read to set correct power output. Before that, for the P5 (Pentium) and P6 (Pentium Pro only) CPUs where produce with different voltages and need a voltage regulator accorded to their specs to …
