Indy RAM

After my Indy refused to boot, I figured out that the only way to bring it back up is to remove 4 out of the installed 8x8MB modules. I did try and clean both the RAM modules and the sockets themselves. But no luck so far. I am stuck with 32MB RAM.

I tried looking on eBay, but I really don't see a lot of true parity, non-EDO RAM being sold in set of fours, which I need now. What would you guys do and where would you buy compatible RAM?

I did check out SGI Depot, but didn't come up with anything there either.

You can identify whether a SIMM is parity and FPM by reading the part number on the chips. See http://www.chipmunk.nl/DRAM/
Companies that service old Macs may have them in stock (but they mostly would not be parity).
If you can't find it elsewhere you can use a company like MemoryX that carries all types of memory at pretty decent prices.

Have you already checked Ian's Parts/Spares page?

Did you try the ram you removed, in place of the 32mb ? ( Just to make sure )
If you did, try each of the 4 in combination with 3 of the 4 known working, to see how many modules failed ( no point in buying 4 if just one is faulty, by example )

robespierre, those are excellent resources, thanks!

johnnym, when I first took a look, I didn't find anything. I see a couple of RAM parts listed for the Indy now. I'll email him and see how to get this going.

mazzinia, I did that. And I also think out of the 4, there is one in particular that is faulty. I see some corrosion.
