Got this VLB card the other day. Nothing special. Was advertised as NOS but is clearly used as it is covered with a fine dust. It works and it wasn't too expensive so I am happy to have it in my collection. PXL_20241129_020432769.jpg I have that exact same card, but it has the 1MB memory chips …

If You read the manual on the retroweb it will answer Your questions. Just get the FK chips. Chances are the writing on the chips has been reprinted, but there seems to be no datasheet for a K only cache chip. The Tag according to the manual is the same as the other chips, even the photo shows that. …

I've had my Diamond Monster Rev D card running as high as 57mhz in the past. I wonder if the memory is what is limiting some of the cards, or were later revisions of the chipset ic's capable of better speeds due to improved silicon?

That's C5 on the socket, which is VSS (GND). Maybe a cpu has been plugged in the wrong orientation? i just checked, so if the cpu was plugged in 180 degrees then that would be VCC going directly into the GND pin on the motherboard. 90 degrees either way is A29 (Address pin) or BS8# which is an …

Are they 3.3v or 5v cpus? D3 is just a data pin, and that's whether it's socket 1,2, or 3. I would say it's a motherboard issue. You could measure the pin to gnd with a multimeter, either connected in the socket or not. This is a very weird problem to have, maybe attach a photo?

What refresh rate are You running at? That's the effect You would get on a crt if It is out of sync. Maybe try setting the monitor driver as LCD not CRT. Try 60hz if not already at that frequency.

I have a bunch of XT motherboards, most NOS, then a massive jump all the way to 486 and beyond. I've never felt a need for 286 or 386 systems. The XT is necessary to play all those earliest 4.77mhz speed sensitive titles, like what was on the apple 2 and other 8 bit computers. I remember playing …

Line 38 of the parts list says 74F245 then at the end 74HCT245 in the Mouser part number. I know the F series are the fastest so the question here is does this card need the 74F245 or will a 74HCT245 suffice?

I highly doubt that would cause any issues. You haven't told us yet whether Any Dos 3DFX games work yet? like Tomb Raider for example.

You are correct. Check more sources of information I guess. EF is at the end though, setup pages, whatever that is. Anyway, more information on the hardware will be helpful.

The Bios size on the downloads from The Retro Web are 1M bit or 128k bytes, so as the photo shows a Winbond chip, it's likely going to be a w27c010, w27e010, or w29ee010. My opinion on the sticker is just pull it off and be done with it. That's just my opinion though.

You wouldn't have a DVI port on it if there was no Digital video out. is there no LCD monitor You can try? I Assume You've tried 1920x1080 60hz as that would be the most compatible. Either it's a compatibility problem or the Digital video out on the video card is dead.

Maybe try it with a LCD monitor, not a tv, could be a compatibility issue. When You say You tried with a DVI to VGA converter, are You talking about an actual powered converter box or just one of those dvi to vga adaptors that used to come with the video cards, as they just route the 4 pin analog …

Make sure the files are not set to read only. This most often happens when copying from a cd to hdd. The proper way to run Dos games is from a Dos boot, not msdos mode or reboot to Dos, but that can be very time consuming and complicated to setup.

I assume from the 3dmark score You are running this on something period correct? Does You monitor support higher than 60hz? You can force the refresh rates to 60hz in the control panel. Voodoo 1 cards sometimes don't work on higher mhz systems. Dos 3dfx version of Tomb Raider is a good test as it …
