Please post a good picture of the video card.

Here with the simm included.

Here without

I saw online that the Rage pro memory is clocked at 100mhz.

The memory simm I bought is rated at 125mhz...

Is this the problem?
Can I update the bios of the card with a new one?

That module should work just fine. Have you tried cleaning the contacts?

How can I clean them?

(cleaning) Alcohol should do the trick. Sometimes I also use naphtha.

Isopropyl?

Yes isopropyl and a q-tip should do the trick. Use the most pure you have, 90% or higher is best.

Also you can use the eraser of a standard no. 2 pencil to clean the contacts, just rub gently until they shine.

You can even rub it with your fingers. Works with old ram sticks

Sorry to write in an old thread but I wanted to know if the problem was solved cause I've also that video card model but only without TV outputs and on a sticker there's the compatibility notice to upgrade to 100-401012 4MB rams but I could find only the same modules code above or the specific 10ns version but still different code. How to be sure they are compatible?

Hello, it never worked

Thanks. It'd be interesting to know what they changed cause SGRAM modules themself seems like similar. Maybe different PCB layouts who knows.

Don't know if it'll help figure out why the module didn't work, but here are some photos of a 4MB module from an AIW Pro.

[edit: I've done a quick comparison of that 1024200400 with my 1024200300 and the top side looks to be very nearly identical. Only difference seems to be the size of what I guess are the pick-and-place location identifier marks, and the physical size of some of the capacitors (though that might just be an illusion caused by different lighting). I would try the card with just the on board 4MB, to test if it auto-detects how much RAM there is, but the machine it was living in hasn't been turned on for <mumble> years so I'd need to check it out first.]

It'd be interesting to know if those modules works, even if I suspect it might depend also on the bios version of each card. I've got a 08/1997 bios on my Rage Pro PCI.
