What ultra resolutions do you see that happens (corruption and issues)? 1024x768 is not that high. 1280x1024 is borderline, but 1200x1600 and 1920x1080 are ultra high resolutions. Ironic that people are trying to do it at high resolutions with a older video card that is not up to this performance …

Since had worked with electronics, and little research on line, photos was invaluable of a original Deskpro 386/25e, I needed to map out the pin out of power supply on this motherboard received from ebay seller. Mystery of the 2 pins can be explained, one of them is for HD LED activity signal input …

The code date on the chips is 1989 will help narrow this down to either late 286 or 386 Nec computer era. Certainly not 486 for sure as it tend to get better than this video card. The years most people bought 286 usually due to cost of 386 machines. By the way when my father bought a PC it was a …

Have anyone currently or had these models? All of these feature cache built in. I'm looking at getting boards and cards to rebuild a 386/33M or 486/33M. Or a XL based on 486/66 XL and use PCI video card in it. Only thing about Deskpro M series is sourcing a memory expansion card. Not going to use …

Yes the motherboard's chipset is what determines the windows support the most. Hence we had to have few machines to cover the areas. DOS for pentium or 486 using ISA or PCI video, WIndow 98se for 440BX/815/865 and some socket 462 boards and mostly are AGP. XP can span from fastest P3, P4 and Core 2 …

Find a place where they clean stuff like jeweller shop ask them to clean these in ultrasonic washer and toss them in and final rinse with 99% alochol in a tupperware. Many of these parts including fuse, switch, fuse holder and, high quality 9 pin connectors, DIN jacks can be sourced new from ebay …

I seem to remember someone saying that the motherboards that have the 4pin P4 plug are not entirely safe from this issue either and you still need a powerful 5V line. Has anybody ever looked into that? OP, are you running the original Thoroughbred 2800+ or a Barton model? Phil's Computer Lab tested …

CAD is about 50 to 80 plus shipping north of 30 to 50. And that's truepower 550W with 40A. I'll just wait and get one. Would like to know about other brands that seasonic made for others as well with fat 5V current? Remember, exchange rate is lopsided. Cheers,

I checked ebay and see used Antec with 30A and other with 40A on 5V but price is high. Is there other quality alternatives other than Antec? Seasonic is thin on this. Cheers,

Barton 2800+ is typically 68 to 70w. Needs very strong 5V current. High quality PSU is a must. Seasonic 750W will do this. Cheers, Jason

Typical. TNT2 series even the strongest one usually manage 286 texels per second and that's Pro. Low end Geforce2 starts at 350 and up on other models of Geforce2 series. Still, I'm curious about what need for TNT2 even Pro for what? I'm talking about how much of games that is not speed sensitive on …

3.3v is taken from un-rectified 5V winding on the PSU via another inductor sized correctly to produce 3.3V. So you will have problems still. Needs fatter QUALITY 5V PSU. Cheers,

Try to find another fan made by OEM brands that has much lower current, this will be much quieter. Your fan is generic. https://www.ebay.ca/itm/NIDEC-U40X12MLZ7-53-12V-0-05A-40-40-10MM-3Pin-Cooling-Fan/264392891917?hash=item3d8f0b5e0d:g:-PwAAOSwSmJdJLv4 https://www.ebay.ca/itm/DELTA-EFB0412MA-4CM-40 …
